When I do this, the stdout looks as expected:</p>\n<p><code>[0] mem.local: [1694367396.133191260, {&quot;Memstats&quot;=&gt;{&quot;Mem.total&quot;=&gt;2006712, &quot;Mem.used&quot;=&gt;1899256, &quot;Mem.free&quot;=&gt;107456, &quot;Swap.total&quot;=&gt;2744316, &quot;Swap.used&quot;=&gt;737692, &quot;Swap.free&quot;=&gt;2006624}}]</code>, so it does successfully add the Memstats key.</p>\n<p>However, on my remote syslog server, I see blank logs appear. The same is noted when I run fluent bit on this remote system with syslog input (to receive from the sender). At first I thought perhaps there may be an issue with the parsing or receiver configuration, but when using the logger command to send a test nested JSON, I still see it show up on my syslog-ng server.</p>\n<p>Observed Outputs:</p>\n<pre><code>//Using Mem.total as syslog_message_key:\n&lt;date&gt; &lt;time&gt; &lt;IP&gt; 1 2023-09-10T19:14:01.132671Z - - - - - 2006712\n\n//Using the Memstats with Nest Filter as syslog_message_key OR using no key (not setting anything):\n&lt;date&gt; &lt;time&gt; &lt;IP&gt; 1 2023-09-10T19:14:33.133314Z - - - - - \n\n//Using logger command to send a simple test nested JSON to the syslog-ng server:\n&lt;date&gt; &lt;time&gt; &lt;IP&gt; 1 2023-09-10T14:01:33.708649-04:00 UbuntuVM vboxuser1 - - [timeQuality tzKnown=&quot;1&quot; isSynced=&quot;0&quot;] {&quot;Memstats&quot;: {&quot;test&quot;:&quot;hi&quot;, &quot;test2: &quot;hello&quot;}} \n\n</code></pre>\n<p>I have also tried using the record_modifier and modify but I get backend failure, and using the following LUA script has resulted in no difference; I don't even see a Memstats key added with it.</p>\n<pre><code>[FILTER]\n Name Lua\n Match *\n call append_record\n code function append_record(tag, timestamp, record) new_record = record new_record[&quot;Memstats&quot;] = record return 1, timestamp, new_record end\n\n[OUTPUT]\n Name stdout\n Match *\n</code></pre>\n<p>I would preferably like to resolve this using the Fluent Bit plugins, as they are geared towards achieving this sort of task. If anyone has done this before or knows how I may be able to send the entire record with all memory data rather than just an integer value for a single key, I would appreciate the help!

For example, when editing my Python files, I call the following formatters, each of which handles a specific part of code:</p>\n<pre><code>vim.api.nvim_create_autocmd({ &quot;BufWritePost&quot; }, {\n pattern = { &quot;*.py&quot; },\n desc = &quot;Auto-format Python files after saving&quot;,\n callback = function()\n local fileName = vim.api.nvim_buf_get_name(0)\n vim.cmd(&quot;:silent !black --preview -q &quot; .. fileName)\n vim.cmd(&quot;:silent !isort --profile black --float-to-top -q &quot; .. fileName)\n vim.cmd(&quot;:silent !docformatter --in-place --black &quot; .. fileName)\n end,\n group = autocmd_group,\n})\n</code></pre>\n<p>Don't forget to add each auto-command to an auto-command group that has the <code>clear</code> flag set to avoid repeatedly loading a command every time a file is resourced. You can read more about auto-commands via the manual <code>:h autocmd</code>.</p>\n"^^ . . . "nvim-lspconfig"^^ . . "<p>I am using lsp-zero &amp; mason to install LSPs, formatters and linters.

"<p>I'm planning on implementing scripting support to embedded project coded in C. I have never done such thing before and found out about eLua.</p>\n<p>My goal is to get a scripting support to my existing C based system. I would like to keep the C code running and doing its thing 'on the background' while the user script is running as well. The user script does not need to directly interface with any hardware, but is intended to build logic, like conditions, loops and timed events and the HW control is all handled in the C side.</p>\n<p>In my use case the system is basically automation controller where the script would be user implemented logic and the C code would handle the interfacing with various interfaces and protocols (already implemented in C). The script can then just say 'turn on lamp number x' and the C code actually does the heavy lifting, packs and transmits the message to the correct lamp.</p>\n<p>The problem I face is that all the examples I've found all either do everything in Lua, or the script is run to completion before any other things can happen. In my case that won't work because the C side needs to listen for inputs to uart for example. UART and the HW in general will be interrupt driven so its ok if the lua side takes some time to process its things.</p>\n<p>I've read the documentation and looked at examples but cannot understand how (if it is possible even) to run a lua script while also running other C code.</p>\n<p>Is there a way to do this in eLua?

If there was some easy way to set it to <code>nil</code>, Lua would have to change the values stored in a million places to <code>nil</code>). You can however set some internal data in your userdata to <em>mark</em> the circle as &quot;destroyed&quot;, and you can write your <code>__index</code> metamethod / all your methods accordingly that they check for this and error on an invalid object (for example, Lua will mark closed files as closed, and any attempt to use them will error).</p>\n<p>(*) resources like files or database connections are an exception here, as it may be important that they are released timely, so newer Lua versions offer the <code>&lt;close&gt;</code> annotation to release variables as they go out of scope using the <code>__close</code> metamethod; in older Lua versions you'd have to manually call <code>:close()</code>.</p>\n"^^ .

Make sure you use { remap = true }.\nlocal make_repeatable_keymap = function (mode, lhs, rhs)\n vim.validate {\n mode = { mode, { 'string', 'table' } },\n rhs = { rhs, { 'string', 'function' },\n lhs = { name = 'string' } }\n }\n if not vim.startswith(lhs, &quot;&lt;Plug&gt;&quot;) then\n error(&quot;`lhs` should start with `&lt;Plug&gt;`, given: &quot; .. lhs)\n end\n vim.keymap.set(mode, lhs, function()\n rhs()\n vim.fn['repeat#set'](vim.api.nvim_replace_termcodes(lhs, true, true, true))\n end)\n return lhs\nend\n</code></pre>\n<p>(Note: this does not implement <code>opts</code> for such as <code>buffer</code>, <code>nowait</code>, <code>silent</code>, etc., but it should be straightforward to extend)</p>\n<p><strong>Example</strong>: If you want to make a keymap <code>&lt;leader&gt;tc</code> mapped to a lua function (or any keymap sequence string) repeatable:</p>\n<pre class="lang-lua prettyprint-override"><code>vim.keymap.set('n', '&lt;leader&gt;tc', make_repeatable_keymap('n', '&lt;Plug&gt;(ToggleComment)', function()\n -- the actual body (rhs) goes here: some complex logic that you want to repeat\nend, { remap = true })\n</code></pre>\n<p>This will:</p>\n<ul>\n<li>Create an internal keymap <code>&lt;Plug&gt;(ToggleComment)</code> that does the job to make the internal keymap repeatable.</li>\n<li>Map <code>&lt;leader&gt;tc</code> to <code>&lt;Plug&gt;(ToggleComment)</code>, which will execute the desired body (rhs).</li>\n<li>Note: Make sure you use <strong><code>{ remap = true }</code></strong>.</li>\n</ul>\n<h3>More detailed explanation and breakdown</h3>\n<p>So in order to make vim-repeat work, in general one should have a keymap (or a command) like:</p>\n<ol>\n<li>BEGIN: A keymap (or command) starts, say <code>&lt;Plug&gt;(MyKeymap)</code>.</li>\n<li>(body -- what is going to be repeated; this is the body (rhs) of the keymap)</li>\n<li>END: call <code>repeat#set(&quot;&lt;Plug&gt;(MyKeymap)&quot;)</code> to mark the <em>keymap</em> sequence to repeat by <code>.</code>.\n<ul>\n<li>Note this is just implemented by <strong><code>feedkeys</code></strong> under the hood -- so need to use <code>nvim_replace_termcodes</code>; also an anonymous function cannot be used.</li>\n</ul>\n</li>\n</ol>\n<p>For keymap, it is very recommended (although not mandatory) to use <a href="https://vimhelp.org/map.txt.html#%3CPlug%3E" rel="nofollow noreferrer"><code>&lt;Plug&gt;</code></a> to create an <em>internal mapping</em>, because this will make key repeat much, much easier to write and understand.</p>\n"^^ .

"<blockquote>\n<p>Is my solution right?</p>\n</blockquote>\n<p>This is not a correct Fisher-Yates shuffle, and the results are not equally probable. This is not obvious, but easy to show with some well-known math.</p>\n<p>Let's call the length of the list <code>n</code>. In each iteration of your loop, you choose a number between <code>1</code> and <code>n</code>. There are <code>n</code> iterations, so there are <code>n^n</code> equally likely ways that all the numbers can be chosen. The number of permutations of the list is <code>n</code> factorial. (Except in trivial small cases), there is no way to divide <code>n</code> factorial permutations evenly into the <code>n^n</code> outcomes, thus it is impossible for all the permutations to be equally likely. For example with <code>n=4</code>, there are 24 permutations, but 256 ways the random numbers can be chosen. 24 doesn't divide into 256 evenly, so there is no way to assign an permutation to each of the 256 random outcomes so that they all appear the same number of times.</p>\n<p>To get the proper Fisher-Yates algorithm, change <code>j = math.random(1, #list)</code> to <code>j = math.random(1, i)</code>. This means that the previous counterargument no longer applies: the first random number is from <code>1</code> to <code>n</code>, then <code>1</code> to <code>n - 1</code>, etc. So, the number of ways the random numbers can be chosen is also <code>n</code> factorial. This doesn't automatically prove that the algorithm works properly; you need to think about it and realize that each permutation can be reached by exactly one way of choosing the random numbers (or you only have to prove that each permutation is possible since the numbers are the same).</p>\n<blockquote>\n<p>One thing I noticed is if I add <code>math.randomseed(1)</code> [...], I always get the same results[...] Why does that happen?</p>\n</blockquote>\n<p><code>math.random</code> is a pseudo-random number generator. This means that it has some hidden internal state, and each time you call it, it does some mysterious but deterministic operation to modify its internal state and return a mysterious number. But, it is not actually random (because common computer operations are inherently always deterministic) (hence &quot;pseudo-random&quot;).</p>\n<p><code>math.randomseed</code> sets the hidden internal state. Because everything is deterministic, if you start with the same state, you will get the same result. This feature can be useful, e.g. to reproduce the same result later, but it is not useful if you just want &quot;random&quot; numbers.</p>\n<p>In Lua 5.4, Lua tries to automatically choose a different starting seed value each time you run the program, so there is not any great need to manually provide a seed when the program starts (but also a no-argument version of <code>math.randomseed()</code> is added to allow this behavior to be invoked explicitly). In earlier versions of Lua it is common to do something like <code>math.randomseed(os.time())</code> so that you get a different seed each time (well, it will be different if at least a second of real time has passed).</p>\n"^^ . . . .

Assuming you want to match <em>exactly</em> the test strings you have given, where the filename may vary in the prefix, but the suffix needs to be <code>_config.json</code>, and the name of the <code>project</code> folder may vary in the suffix, use the pattern <code>^/tmp/project[^/]+/([^/]+)_config.json</code> for <code>string.match</code>:</p>\n<pre><code>print((&quot;/tmp/project[^/]+/server_config.json&quot;):match&quot;^/tmp/project1/([^/]+)_config.json&quot;) -- server\n</code></pre>\n<p>Note also the nuances in the patterns by the other answerers:</p>\n<ul>\n<li><code>/tmp/project%d+/(.-)_config.json</code> misses <em>anchors</em> (<code>^</code> and <code>$</code>). (Assuming this is unintended) this is a frequent mistake in Lua patterns. This will match anything that has something matching <code>/tmp/project%d+/(.-)_config.json</code> anywhere in it; it will also accept the <code>*_config.json</code> file being included in a subdirectory of the project. The following will match, for example: <code>/foo/bar/tmp/project42/subfolder/server_config.json.blah.blub</code>, and the match would be <code>subfolder/server</code>.</li>\n<li><code>.*/(.+)_config.json</code> effectively matches just the filename, and removes a suffix of <code>_config.json</code>. Note that this also isn't anchored. A <code>^</code> anchor isn't needed here, as <code>.*</code> being greedy already suffices to start at the start of the string, but this pattern will allow arbitrary suffixes after <code>_config.json</code>. It will also allow arbitrary parent folders as it matches just the filename. <code>/blah/blub/server_config.json.blah.blub</code> would match as just <code>server</code>.</li>\n<li><code>/tmp/project[1-9]*/(.+)_config.json</code> is similar to the first pattern in that it isn't anchored.

If you reach a certain line point, you will want to create 5 (in this case) new tables in mZ.

But since pandoc 3.0 there is the new <a href="https://github.com/jgm/pandoc/releases?page=2" rel="nofollow noreferrer"><em>complex figures</em></a> approach and, so far, I couldn't figure out how to change the LaTeX macro used for the captions with this new behaviour.</p>\n<p>I tried something like that (Adapted from <a href="https://stackoverflow.com/a/71296595/19647155">here</a>:</p>\n<pre class="lang-lua prettyprint-override"><code>if FORMAT:match 'latex' then\n function RawBlock (raw)\n local caption = raw.text:match('\\\\caption')\n if caption then\n raw:gsub('\\\\caption', '\\\\sidecaption')\n end\n return raw\n end\nend\n</code></pre>\n<p>But nothing happened.</p>\n<p>The main challenge for me are my more-or-less non-existing lua skills. I just never had to use it for my daily tasks. I thought about using <code>awk</code> or <code>sed</code> to edit the <code>.tex</code> file itself using a regex-substitution, but that should remain an absolute stopgap, since it makes the whole workflow less portable.</p>\n<p>Thus, I'm hoping for a hint/a solution in form of a pandoc-lua script which 1. helps me to achieve the goal, and 2. improve my understanding of lua and the <em>complex figures</em> approach for similar future tasks.</p>\n<p><strong>Edit</strong></p>\n<p>The plain LaTeX solution suggested by Julien is not a real option. The <code>\\caption</code> macro is very complex in the backend and cannot be copied on the fly via <code>\\let</code>, <code>\\NewCommandCopy</code> or something similar. Even after doing so with e.g. <code>\\NewCommandCopy{\\oldcaption}{\\caption}</code> and then setting <code>\\RenewDocumentCommand{\\caption}{o m}{\\sidecaption[#1]{#2}}</code> nothing changes and the definition of <code>\\caption</code>, checked with <code>\\meaning</code> or something similar, stays the same as before (even <code>\\DeclareDocumentCommand</code> doesn't work).</p>\n<p>In the end, it might be possible to somehow change the <code>\\caption</code> macro itself. But the effort might not be worth the result (and its more of a question for TeX.SE).</p>\n<p>There must be a simpler solution using Lua. Maybe the writer option also suggested by Julien is worth a try. But for that, my missing Lua skills remain as an obstacle. Right now, I'm using a sed script, which works just fine. But it limits the usage to Unix-Systems. Thus, a plain pandoc solution still is the goal to go.</p>\n"^^ .

One way to do it would be using a &quot;right curry&quot; which appends arguments to a function call:</p>\n<pre class="lang-lua prettyprint-override"><code>function curry_right(f, ...)\n local args, n_curried = {...}, select(&quot;#&quot;, ...)\n return function(...)\n local n = select(&quot;#&quot;, ...)\n local concat = {...}\n for i = 1, n_curried do\n concat[n + i] = args[i]\n end\n return f(table.unpack(concat, 1, n + n_curried))\n end\nend\n</code></pre>\n<p>Then you could just do:</p>\n<pre class="lang-lua prettyprint-override"><code>chaincall(range(0, 100),\n curry_right(List.filter, isEven, numbers),\n curry_right(List.map, double, evenNumbers),\n curry_right(List.iter, printNumber, doubledNumbers))\n</code></pre>\n<p>similar to F# (assuming suitable definitions of <code>range</code> etc.)</p>\n<hr />\n<p>As is often the case in Lua, it gives you the power to implement this yourself, pushing tradeoffs and design decisions on you.</p>\n<p>Even with the simple implementations I have provided, there are discussions to be had:</p>\n<ul>\n<li>How to namespace these functions. For simplicity, I'm just &quot;polluting&quot; the global namespace here.</li>\n<li>How to implement these functions. You could consider directly implementing a <code>compose_multiple</code> using a table of functions, for example. You could consider using the identity function and making a fold which requires a vararg with at least one element.</li>\n<li>How / whether to optimize these functions. I brushed performance concerns aside here.</li>\n</ul>\n<p>A related library worth mentioning is <a href="https://github.com/luafun/luafun" rel="nofollow noreferrer"><code>luafun</code></a>, which provides functions like <code>filter</code> and <code>map</code>. That library also showcases another frequently chosen way of (emulating) this &quot;chaining&quot;: By means of &quot;methods&quot; on &quot;objects&quot; (tables with metatables) which in turn return the objects. For example you could have an &quot;iterator&quot; object. Calling <code>iterator:filter(f)</code> would return a new iterator, on which you could then call <code>map</code>: <code>iterator:filter(f):map(g)</code> etc.</p>\n<hr />\n<p>Using Lua's metatables, you could even get some syntactic sugar. Let's repurpose the right shift operator (<code>f &gt;&gt; g</code>) for &quot;flipped&quot; function composition:</p>\n<pre class="lang-lua prettyprint-override"><code>debug.setmetatable(function()end, {__shr = function(g, f) return function(...) return f(g(...)) end end})\nfunction square(x) return x^2 end\n(square &gt;&gt; print)(4) -- 16.0\n</code></pre>\n<p>(In older Lua versions, you'd have to use a different operator. Also note that this probably isn't the best idea in &quot;serious&quot; code due to performance and readability concerns; such &quot;abuse&quot; of the debug library is usually frowned upon in &quot;serious&quot; code, and many &quot;safe&quot; environments may remove or restrict the <code>debug</code> library altogether. Static analysis tools might also get confused.)</p>\n"^^ . "1"^^ . "@LucRiffault Huh, that is strange. What is the platform that you're using?"^^ . "1"^^ . . . "0"^^ . "0"^^ . . "debugging"^^ . .

"<p>To write and read to and from an open file:</p>\n<p>Whenever you successfully perform any <em>read</em> or <em>write</em> operation on a file - regardless of the <em>mode</em> the file was opened with - the <em>file position indicator</em> for the file will have changed.</p>\n<p>For <code>r+</code> (read extended), the <em>file position indicator</em> is initially set to the start of the file, and both reading and writing are allowed<sup>1</sup>. Starting by reading the entire file then places the indicator at the <em>end of the file</em>. Immediately following this with a write operation will then appear as an append, and the file position indicator will <em>still be at the end of the file</em>. Attempting to read at this point will not return any data from the file - you must first <em>seek</em> to a position with data.</p>\n<p>This can be done with <a href="https://www.lua.org/manual/5.4/manual.html#pdf-file:seek" rel="nofollow noreferrer"><code>file:seek</code></a>. For example,</p>\n<pre class="lang-lua prettyprint-override"><code>file:seek('set')\n</code></pre>\n<p>places the file position indicator at the <em>start</em> of the file.</p>\n<p><sup>1.</sup> Note that because Lua's I/O is a very thin wrapper around C's I/O, we should refer to documentation on <a href="https://en.cppreference.com/w/c/io/fopen" rel="nofollow noreferrer"><code>fopen</code></a> to learn the order in which operations may be performed on a file opened for both reading (input) and writing (output):</p>\n<blockquote>\n<p>In update mode (<code>'+'</code>), both input and output may be performed, but output cannot be followed by input without an intervening call to <a href="https://en.cppreference.com/w/c/io/fflush" rel="nofollow noreferrer">fflush</a>, <a href="https://en.cppreference.com/w/c/io/fseek" rel="nofollow noreferrer">fseek</a>, <a href="https://en.cppreference.com/w/c/io/fsetpos" rel="nofollow noreferrer">fsetpos</a> or <a href="https://en.cppreference.com/w/c/io/rewind" rel="nofollow noreferrer">rewind</a>, and input cannot be followed by output without an intervening call to <a href="https://en.cppreference.com/w/c/io/fseek" rel="nofollow noreferrer">fseek</a>, <a href="https://en.cppreference.com/w/c/io/fsetpos" rel="nofollow noreferrer">fsetpos</a> or <a href="https://en.cppreference.com/w/c/io/rewind" rel="nofollow noreferrer">rewind</a>, unless the input operation encountered end of file.

Latex environment in the output file without any error messages. Thus, the method seems to work, but I just can't figure out how to access the field values of the Figure block.</p>\n<p>The test file ast-test.txt only contains a few lines:</p>\n<pre class="lang-markdown prettyprint-override"><code>---\ntitle: A title\n---\n\n# Einleitung\n\nSome text\n\n![caption *to* an image](counter_plot_new_periods.png)\n</code></pre>\n<p><strong>Edit</strong></p>\n<p>I tried an approach using a Lua filter instead of a Lua custom writer (inspired from <a href="https://stackoverflow.com/a/66982937/19647155">this answer</a> by @tarleb):</p>\n<pre class="lang-lua prettyprint-override"><code>function Figure (elem)\n raw_elem = '\\\\begin{figure*}\\n' ..\n '\\\\centering\\n' .. \n '\\\\includegraphics[width=0.9\\\\textwidth]{' .. elem.content ..

"<p>I am attempting to decode PNG files in Luau, and so far I have made great progress, to the point of being able to make out the image in the final, decoded result, despite clearly being incorrect. The one thing I need to fix is the de-filtering (reconstruction) process.</p>\n<p>So far I have correctly parsed the different chunks of the file, and decompressed the IDAT chunk with an external library. I have also converted the raw data to the format I need (a table consisting of numbers between 0-1, 4 for each pixel, each number corresponding to an RGBA channel), but the data is &quot;filtered&quot; before being compressed in order to optimize the compression. This of course means that I need to reverse this process (de-filter) in order to view the correct results.</p>\n<p>For every scanline, I am correctly getting the byte used to determine which <a href="https://www.w3.org/TR/png-3/#9Filter-types" rel="nofollow noreferrer">filter function</a> was used on the scanline.

That &quot;method&quot; can take parameters <code>i, j</code> then: <code>arr:get(i, j)</code> desugars to <code>getmetatable(arr)[&quot;get&quot;](arr, i, j)</code>. You just need to set the metatable up such that <code>getmetatable(arr)[&quot;get&quot;]</code> resolves to your <code>array2d_get</code> function (for example by setting <code>__index = {get = array2d_get}</code>).</p>\n<p>I would also argue that this is probably cleaner as you add methods to your 2d arrays. Otherwise, something like <code>arr:push(42)</code> will always first have to check whether <code>&quot;push&quot;</code> is a valid index, then resolve to the method if it isn't. This is also not great for performance (of method calls).</p>\n<h4>Array of Arrays</h4>\n<p>Move from your &quot;2d array&quot; userdata back to &quot;1d array of 1d arrays&quot;, then everything will work naturally, albeit with somewhat more memory overhead (and negative implications e.g. for cache locality and GC pressure, so this also comes at a runtime cost).</p>\n<h4>&quot;Row&quot; Type</h4>\n<p>You could make <code>arr[y]</code> return a &quot;row&quot; userdata object for the y-th row (effectively just a fancy pointer) which, when indexed, would give you the x-th element in the row.</p>\n<p>Creating such &quot;row&quot; objects for every indexing operation might be a problem performance-wise, however.</p>\n<h4>Compound Index Type</h4>\n<p>For the sake of completeness, you could also use a table (or a userdata object, or a string, or a closure...) to implement something like <code>arr[{x, y}]</code> or <code>arr[Index2D(x, y)]</code>.

This is relatively simple. However, this method would have its downside when you have a complex game loop/system. It could be quite complex to handle where players are and teleporting the correct players and then respawning the correct players back to the lobby. Also, if you have multiple game loops running simultaneously you could end up with timing and lag issues.</p>\n</li>\n<li><p><strong>The second approach is having each game/map in a different place.</strong> This could make it slightly more difficult to start off with, however if you have a complex game, you would be glad you went through the slightly steep learning curve of handling players and place teleports.

It also has the extra advantage that all players on the same map are in the same server, as well as the advantage of making it easier to have different lighting/environment settings for different maps.</p>\n</li>\n</ol>\n<p>So, I would recommend if players separate in your lobby to play different maps you should use different places, but if you game is like Murder Mystery 2 or Arsenal for example you should keep all players in the same place and teleport them to the selected map.</p>\n"^^ . . . . . . . "<p><code>acc_1:deposit(100.0)</code> is syntax sugar for <code>acc_1.deposit(acc_1, 100.0)</code>. The immediate issue you have is that <code>acc_1.deposit</code> is <code>nil</code>. First off, <code>acc_1</code> is empty. This is sort of by design -- it is a <code>proxy</code> returned by <code>AccountProxy:new</code>. Because the key doesn't exist, it will check the metatable. The <code>__index</code> method looks in the corresponding <code>account</code> table, but this only has <code>balance</code>. There is nothing connecting <code>acc_1</code> to <code>AccountProxy.deposit</code>. You could call <code>AccountProxy.deposit(acc_1, 100.0)</code>, but this is not really a traditional object-oriented pattern.</p>\n<p>You want <code>acc_1.deposit</code> to be associated with the actual method, so you must either put <code>deposit</code> directly in <code>acc_1</code>, or else make it accessible via the metatable. I think these are both fine, but I probably prefer the second given that you don't want to access any local variables defined in <code>new</code> from your instance methods. E.g.</p>\n<pre><code>function AccountProxy:new()\n local proxy = {}\n -- ...\n function proxy:deposit()\n -- do the deposit ...\n end\n -- ...\n return proxy\nend\n</code></pre>\n<p>or</p>\n<pre><code>function AccountProxy:new()\n local proxy = {}\n setmetatable(proxy, {\n __index = AccountProxy,\n })\n -- ...\n return proxy\nend\n</code></pre>\n<p>Using the metatable for this purpose could interfere with your existing metatable, but I think your existing metatable is sabotaging your purpose. Supposedly the purpose of the proxy here is encapsulation -- to prevent outside code from accessing <code>balance</code>. The metatable you give just allows any code (inside or outside) to access balance. (Yes, it is the kind of metatable used in the referenced example, but as I see things, it is just an example of forcing access to go through a certain path rather than specifically making that path use metatable.)</p>\n<p>Without the metatable, you need another way to retrieve <code>balance</code> from <code>proxy</code>; and you have already partially implemented this as suggested by the exercise. Given <code>proxy</code>, you can lookup <code>accounts[proxy]</code> e.g.</p>\n<pre><code>function AccountProxy:getBalance()\n return accounts[self].balance or 0\nend\n</code></pre>\n<p>Assuming outside code doesn't have access to <code>accounts</code> (which can be enforced by lexical scoping), it then can't directly interact with <code>balance</code> except through the provided methods.</p>\n<p>(Using <code>accounts</code> is not the only way to do such a mapping or get this kind of encapsulation.

"<p><a href="https://stackoverflow.com/a/77281716/2505965">Oka has pointed out</a> that <code>a.b[o] = d</code> contains two index operations, so you have to create metatables for each array. BTW, as I commented under the previous deleted question, I suggest that you use third-party libraries to complete the binding, as it is quite complex to implement. I will put aside the <code>pf</code> field for now, the basic principle is the same. Let's begin with a mistake:</p>\n<pre><code>lua_pushlightuserdata(L, ms);\nluaL_getmetatable(L, &quot;mystruct&quot;);\nlua_setmetatable(L, -2);\n</code></pre>\n<p>This looks quite reasonable, but I believe the result is not what you want, that's because from <a href="https://www.lua.org/manual/5.4/manual.html#2.4" rel="nofollow noreferrer">the manual</a> you can read:</p>\n<blockquote>\n<p>Tables and full userdata have individual metatables, although multiple tables and userdata can share their metatables. Values of all other types share one single metatable per type; that is, <strong>there is one single metatable for all numbers, one for all strings, etc</strong>. By default, a value has no metatable, but the string library sets a metatable for the string type.</p>\n</blockquote>\n<p>If you set the metatable <code>mystruct</code> for your struct, you cannot set another metatable for other arrays. The solution is to create full userdata to store the struct and the arrays. You just need to save pointers, so I write two functions to simplify these operations.</p>\n<pre><code>void newpointerud(lua_State* L, const char* mt, int nuv, const void* data) {\n auto p = (const void**)lua_newuserdatauv(L, sizeof(void*), nuv);\n luaL_setmetatable(L, mt);\n *p = data;\n}\n\nvoid* getpointerud(lua_State* L, int idx) {\n return *(void**)lua_touserdata(L, 1);\n}\n</code></pre>\n<p>Next, you need to write the corresponding meta methods for <code>int[]</code> and create a metatable.</p>\n<pre><code>// ..options[idx]\nint mt_c_int_array_index(lua_State* L) {\n int* options = (int*)getpointerud(L, 1);\n int idx = lua_tointeger(L, 2);\n if (idx &gt;= 0 &amp;&amp; idx &lt; 20)\n lua_pushinteger(L, *(options + idx));\n else\n lua_pushnil(L);\n return 1;\n}\n\n// ..options[idx] = value\nint mt_c_int_array_newindex(lua_State* L) {\n int* options = (int*)getpointerud(L, 1);\n int idx = lua_tointeger(L, 2);\n if (idx &gt;= 0 &amp;&amp; idx &lt; 20)\n *(options + idx) = lua_tointeger(L, 3);\n else\n luaL_error(L, &quot;Out of index&quot;);\n return 0;\n}\n\n.....\nluaL_Reg mt_c_int_array[] = {\n { &quot;__index&quot;, mt_c_int_array_index },\n { &quot;__newindex&quot;, mt_c_int_array_newindex },\n {NULL, NULL}\n};\nluaL_newmetatable(L, &quot;mt_c_int_array&quot;);\nluaL_setfuncs(L, mt_c_int_array, 0);\n</code></pre>\n<p>Third is to use full userdata to package your struct and arrays. Here, you usually don't want to create a new userdata every time you access the <code>option</code> array. You can use the user value of the userdata to pre save the userdata of the option array.</p>\n<pre><code>newpointerud(L, &quot;mystruct&quot;, 1, ms); // 1 user value\nnewpointerud(L, &quot;mt_c_int_array&quot;, 0, ms-&gt;option);\nlua_setiuservalue(L, -2, 1);\n</code></pre>\n<p>Finally in your <code>mystruct_index</code> function, return this user value.</p>\n<pre><code>....\nelse if (strcmp(field, &quot;option&quot;) == 0) {\n lua_getiuservalue(L, 1, 1);\n}\n....\n</code></pre>\n"^^ . . .

"<p>There are two relevant Lua quirks, one of which I would suspect to be at play here:</p>\n<ul>\n<li>String - number coercion, but strict equality checking;</li>\n<li>Use of floats, but printing them inexactly, hiding rounding errors</li>\n</ul>\n<p>Let's first simplify your example:</p>\n<pre class="lang-lua prettyprint-override"><code>function f(x)\n if x == 1 then\n return 0\n end\n return 1\nend\n</code></pre>\n<p>So <code>f(1)</code> is <code>0</code>, and <code>f(x)</code> is <code>1</code> for <em>every <code>x</code> that does not equal <code>1</code></em>.</p>\n<h4>Strings that quack like numbers</h4>\n<p>Lua has a controversial &quot;feature&quot; where it coerces strings to numbers if you do arithmetic on them, and coerces numbers to strings if you do arithmetic on them; <code>print</code> just calls <code>tostring</code> internally, which doesn't quote strings, so strings very much &quot;quack like numbers&quot;. However, testing for equality (or table indexing) is &quot;strict&quot;; it also requires the types to match. See this example:</p>\n<pre class="lang-lua prettyprint-override"><code>-- Oops! This should be a number.\n-- In practice this might be something less obvious like a function returning a string.\nlocal x = &quot;1&quot;\nprint(x + 2) -- 3, we can do arithmetic as if it was a number!\nprint(x) -- 1, it looks just like it was a number!\nprint(type(x)) -- string\nprint(&quot;1&quot; == 1) -- false, the types don't match\nprint(f(x)) -- 1, because &quot;1&quot; ~= 1\n</code></pre>\n<p>The solution here, assuming <code>x</code> is a string which comes from a file or similar, is to <code>tonumber(x)</code> (or equivalently: <code>x + 0</code>, which behaves roughly like <code>assert(tonumber(x))</code>).</p>\n<h4>Rounding errors</h4>\n<p>Lua uses floats to represent numbers. Floats can represent integers up to 2^53 accurately (without loss of precision), so very often this is not an issue when working with integers. However, you can construct floats that are very close to integers, but aren't integers under the hood. Unfortunately Lua <em>rounds</em> numbers when printing them, so you don't see this if you insert debug prints. Consider:</p>\n<pre class="lang-lua prettyprint-override"><code>local x = 0.2 + 6 * 0.3\nprint(x) -- 2.0\nprint(x == 2) -- false, what? how does 2 not equal 2?\n</code></pre>\n<p>To uncover this, print <code>x</code> to 17 digits of precision:</p>\n<pre class="lang-lua prettyprint-override"><code>print((&quot;%.17g&quot;):format(0.2 + 6 * 0.3)) -- 1.9999999999999998\n</code></pre>\n<p>If you know that you're working with inaccuracies, you should do comparisons with some &quot;room for error&quot;. So instead of testing <code>x == 1</code>, you would test <code>math.abs(x - 1) &lt; 1e-6</code>, where <code>1e-6</code> would be your (absolute) margin for error in this example. (Note: A relative margin for error may be more appropriate sometimes; floats in particular guarantee certain relative errors).</p>\n<hr />\n<p>Side note: In many languages with <code>switch</code>es, pattern matching or similar, a function and a <code>switch</code> + <code>return</code> may be an idiomatic way to implement this. However, given that this is just a mapping from some numbers to other numbers, you would usually use a table in Lua:</p>\n<pre class="lang-lua prettyprint-override"><code>local mirrored_numbers = {\n [2] = 8,\n [3] = 7,\n -- ... and so on\n}\nlocal function mirror_number(x)\n return mirrored_numbers[x] or 99\nend\n</code></pre>\n<p>(also, there seems to be a simple correspondence between &quot;mirrored&quot; numbers and <code>x</code> (<code>if angleNumber &gt;= 2 and angleNumber &lt;= 8 then return 10 - angleNumber end</code>), unless you just simplified it for this example; why not leverage that?)</p>\n"^^ .

"<p>Hello Stack Exchange Community,</p>\n<p>I am facing a challenging issue with a project that involves interfacing between C and Lua code. The project utilizes Lua for scripting and C for certain critical computations. However, I'm encountering errors that seem to occur within the C code but are triggered via Lua.</p>\n<p>The primary snippet causing the issue involves an xpcall function in Lua that wraps a C function call:</p>\n<p><code>xpcall(function() ffiC.gkyl_range_init(r, r._ndim, r._lower, r._upper) end, function() print(&quot;Error in gkyl_range_init&quot;) end)</code></p>\n<p>Despite using <code>xpcall</code> to catch errors, I am still experiencing C errors without the corresponding print statement. This raises questions about how I can accurately trace the Lua-C interface to pinpoint the exact source of the error.</p>\n<p>**Specifically, my challenge is:\n**</p>\n<p>Obscured C Errors: Even with <code>xpcall</code>, the error messages originating from the C library aren't being properly captured or displayed, leaving me unsure about the exact cause. I can fix the errors, but I ultimately want to work out how the code can error in a graceful way rather than spitting out an error in the C code with no context of what called it in the Lua scripting.</p>\n<p>**An Alternative Approach I've Considered:\n**</p>\n<ul>\n<li>Using GDB for debugging: I've attempted to debug the code using GDB. However, the backtrace provided within GDB seems limited, indicating &quot;No stack&quot; and referencing missing debug symbols for specific components (openmpi040101-cuda111-gcc-runtime-4.1.1-126.sdl8.mellanox.x86_64). Our code is run on servers that, it seems, don't support the GDB interface. I've filed a ticket with the machine I work on. It seems nobody working on our code has attempted to use GDB to debug it.</li>\n</ul>\n<p>**Seeking Solutions:\n**</p>\n<p>I'm reaching out to the community to gather insights and possible solutions to effectively debug and trace errors occurring between the Lua and C codebases. Any advice, debugging strategies, or thoughts on what might be causing the obscured C errors when triggered from Lua would be greatly appreciated.</p>\n<p>Thank you for your time and assistance.</p>\n<p>What did you try:</p>\n<p>I've been working on a project where Lua scripts interface with a C codebase using the foreign function interface library. However, I encountered issues where errors originating from the C layer were not adequately traced back to their corresponding Lua code, making debugging challenging.</p>\n<p>To address this, I attempted to implement error-handling mechanisms within Lua using the xpcall function. Despite wrapping critical C function calls within xpcall to capture errors, the C errors persisted without triggering the specified error-handling function.</p>\n<p>Additionally, I used GDB for debugging to trace these errors further. However, I faced difficulties as the debug symbols seemed to be missing, resulting in incomplete or unhelpful stack traces.</p>\n<p>What were you expecting:</p>\n<p>Ideally, I was expecting that by using xpcall, I could intercept C errors originating from Lua-invoked C functions and subsequently handle them gracefully within Lua. I anticipated that this error-handling approach would provide more informative error messages, allowing for easier identification of the source of the problem within the Lua codebase.</p>\n<p>Moreover, when employing GDB, I anticipated having access to the complete stack trace and debug symbols, which would help pinpoint the exact location or function in the C code that triggers the error. This would have enabled a more detailed analysis and debugging of the issue at the C level.</p>\n"^^ . . "0"^^ . . "neovim"^^ . "lookup"^^ . "0"^^ .

"<p>The technical term for what you're trying to do is called &quot;<a href="https://en.wikipedia.org/wiki/Function_overloading" rel="nofollow noreferrer">function overloading</a>&quot;. And currently it's not possible in Lua or Luau. An <a href="https://devforum.roblox.com/t/luau-function-overloading/736109" rel="nofollow noreferrer">engine feature request</a> was made for it back in 2020, but that didn't get much traction.</p>\n<p>You cannot have multiple functions with the same name with different signatures. In your example, think of the table <code>var</code> as as a collection of buckets. When you define the <code>get(a:number):any</code> function, you put it into the bucket named <code>get</code>. The next time you try to define <code>get():any</code>, you empty out the bucket named <code>get</code> and replace it with the new function. You can only have one thing in each bucket, or more technically, you can only have one value defined on any key in a table.</p>\n<p>However, if you want to achieve something <em>like</em> function overloading, vanilla Lua does allow you to <a href="https://www.lua.org/pil/5.2.html" rel="nofollow noreferrer">call a function with any number of arguments</a>. This is called a variadic function, they are very useful and <a href="https://luau-lang.org/typecheck#variadic-types" rel="nofollow noreferrer">Luau supports them</a> too.</p>\n<pre class="lang-lua prettyprint-override"><code>local var = {}\nfunction var.get(...):any\n local args = {...} -- store all the extra arguments in an array\n --print(...) -- print out the arguments provided to get\n\n -- figure out how people have called this function\n if #args == 0 then -- called as get()\n print(&quot;get() called with no arguments!&quot;)\n else if #args == 1 then\n print(&quot;get() called with one argument : &quot;, args[1])\n else\n print(&quot;get() called with many arguments : &quot;, ...)\n end\n\n return args\nend\n\n-- allows you to use it like...\nvar.get()\nvar.get(&quot;hello&quot;)\nvar.get(&quot;this&quot;, &quot;is&quot;, &quot;a&quot;, &quot;test&quot;, 123, false)\n</code></pre>\n<p>Personally, I wouldn't recommend doing it this way, this is a scenario where just because you can doesn't mean you should. The flexibility to call your function any way you want doesn't justify the amount of headache needed to make this work. If you're using Luau, you won't get any code assistance from the linter. When an error is thrown, you'll need to do more investigation to figure out how the function was called. It is cleaner to simply create multiple functions for the different signatures.</p>\n<pre class="lang-lua prettyprint-override"><code>local var = {}\nfunction var.get()\n print(&quot;get()&quot;)\nend\nfunction var.getOne(n : number)\n print(&quot;getOne&quot;, n)\nend\nfunction var.getTwo(n : number, s : string)\n print(&quot;getTwo&quot;, n, s)\nend\n</code></pre>\n"^^ . . . . . . . . .

Developers looking to display loading progress should load assets one at a time (see example below).</p>\n</blockquote>\n<p>This means that certain assets may be re-added to the queue if necessary, which means that the code for your callback may run twice inside, that could be a possible cause of your error.</p>\n<p>The first link is related to a bug report that marks the unreliability of .IsLoaded, with a follow-up that it hasn't been fixed yet.</p>\n<p>To give you a potential solution is, to instead of using a callback function, get the assets from the queue and check it's status intermittently, like so:</p>\n<pre class="lang-lua prettyprint-override"><code>local retryLimit = 12\nlocal retryCount = 0\nrepeat task.wait(2) retryCount+= 1 until ContentProvider:GetAssetFetchStatus(DayTheme) == Enum.AssetFetchStatus.Success or retryCount &gt; retryLimit\n</code></pre>\n"^^ . .

(We saw an example previously in this chapter, where we prefixed a return to an expression being loaded.) Write a function loadwithprefix that works like load, except that it adds its extra first argument (a string) as a prefix to the chunk being loaded.\nLike the original load, loadwithprefix should accept chunks represented both as strings and as reader functions. Even in the case that the original chunk is a string, loadwithprefix should not actually concatenate the prefix with the chunk. Instead, it should call load with a proper reader function that first returns the prefix and then returns the original chunk.</p>\n<pre><code>function loadwithprefix(prefix, chunk)\n\nlocal prefixflg = true\nreturn function(...)\n local x = select(1, ...)\n local env = { x = x, __index = { _G = _G } }\n\n if not prfxflg then\n prfxflg = true\n return load(prefix, nil, nil, env)\n else\n return load(' return ' .. code(), nil, nil, env)\n end\nend\nend\n\nlocal line = io .read()\nlocal f = loadwithprefix('local x = ...; return x ', function(...) return line end)\n\nfor i = 1, 10 do\n print(string.rep('*', f(i)()))\nend\n</code></pre>\n<p>I get : bad argument #2 to 'rep' (number expected, got nil) meaning i cannot evaluate the local x = ...; return x to actually return 1 from the for-loop statement.

The <code>local</code> keyword should only be used when defining the variable, not referencing it. Additionally, you seem to be attempting to compare <code>face</code> to the first entry of the table via <code>face (t1)</code>, this is very wrong, and should be done via <code>face == t[1]</code>. Note that <code>[1]</code> is used to retreive the value at position <code>1</code> from the table <code>t</code>, and equality is checked with the equality operator, <code>==</code>. Finally, you have not closed your <a href="https://www.lua.org/pil/4.3.1.html" rel="nofollow noreferrer"><code>if then</code></a> statement. Lua, unlike other langauges, does not support single-expression statements, and <strong>must</strong> be closed with an <code>end</code>.</p>\n<pre class="lang-lua prettyprint-override"><code>if local (t2) then print (&quot; :) &quot;)\n</code></pre>\n<p>This contains many of the same assumptions as the previous line, though for reasons I cannot assume, you have neglected to include <code>face</code>. Additionally, this <em>should</em> probably be an <code>elseif</code> statement, rather than just another <code>if</code> statement, if the behaviour is intended to be exclusive.</p>\n<p>All together, and with additional formatting, your code should now read</p>\n<pre class="lang-lua prettyprint-override"><code>print ('Hello, make a face, ')\nlocal face = io.read()\nlocal t = {&quot;:)&quot;, &quot;:)&quot;}\nif face == t[1] then \n print (&quot; :0 &quot;)\nelseif face == t[2] then\n print (&quot; :) &quot;)\nend\n</code></pre>\n<p>I strongly suggest reading up on the <a href="https://www.lua.org/pil/1.html" rel="nofollow noreferrer">Basics of Lua</a>, or even some tutorials, as you seem to be just guessing about the syntax.

If the sandboxed code's &quot;own functions&quot; are simply these functions, things are easy. We can detect when new functions are added via a <code>__newindex</code> metamethod and immediately add them to the <code>validfunc</code> set.</p>\n<p>However, the sandboxed code you give as an example doesn't have any functions of this kind -- so we see that this fails for functions that aren't added to the environment table like local functions, or inner functions.</p>\n<p>Also, this method is potentially insecure -- the file can whitelist any function simply by adding it to <code>chunkEnv</code>. (This already seems like a vulnerability in the existing code if <code>validfunc</code> is used later, but adding immediately would allow any read-accessible function to be used inside the <code>f()</code> invocation, not just later. But also, it is already allowed for a newly defined function to call a forbidden function as long as that call doesn't happen when the hook is in place (at load time), but maybe that is intended?)</p>\n<p>Although a lexical closure is philosophical linked to the environment in which it is instantiated, I don't think we can use this in Lua. The only accessible link of this kind a Lua function has is via upvalues, and functions in the sandbox do not need to have <code>chunkEnv</code> as an upvalue -- they may define a new environment, or they might not use <code>_ENV</code>. (And in general, there is no guarantee a forbidden function can't end up using <code>chunkEnv</code>.)</p>\n<p>In terms of book-keeping, then, we are left with debug info. The <code>source</code> field of the function debug info record seems like the most appropriate thing to check here. However, depending on the threat model, I would be somewhat worried about the possibility of a forbidden function ending up with a valid <code>source</code> -- do the file system and loading model allow two files to end up with the same <code>source</code>? Does the attacker have access to <code>package.loaded</code>? (With loading binary chunks this is an even bigger problem, but loading binary chunks is also a bad idea for other reasons, and not in play here.)</p>\n<p>(If you know that only C functions are forbidden, I guess some safety can be gained by checking whether functions are C or Lua.)</p>\n<p>I would really want to whitelist a function immediately after it is created (by the <code>CLOSURE</code> bytecode operation) at which time we could check that the currently executing function is allowed to created whitelisted functions (e.g. if it is itself whitelisted, which would always be true if we can only execute whitelisted functions). But, I don't think there is a way to hook this event (at least, not without a lot of work and probably breaking some abstraction barriers like e.g. executing in a software VM at which point the problem is trivial anyway).</p>\n<p>Note also that things like inner functions can't necessarily be whitelisted at the time the file is loaded because they may not even exist until runtime. (The prototype exists, but the prototype is not the Lua function object.) But, if there is no hook protection at runtime, there is nothing that would prevent these from executing at runtime since there is simply no protection at all about calling any kind of function (as discussed above).</p>\n<p>This is also a problem with whitelisting inner functions from trusted APIs. For example, how do you make <code>string.gmatch</code> usable? Each time you execute this function, it returns a new C closure. You would have to hook and whitelist such functions. (And, now we should worry about running out of memory, so maybe using a weak table is prudent.)</p>\n<p>I think sandboxing in this way seems dubious -- not only because of the difficulties above, but also because an attacker may cause trouble by a means other than calling a function like modifying some globally accessible table. (A natural way to fix this is to avoid giving access to sensitive data, but then we could also avoid giving access to sensitive functions...) I haven't read the book, so I don't really have an informed opinion on what kind of answer it is expecting and maybe I don't really understand what kind of protection it is trying to provide. In the context of an exercise, I wouldn't worry about it if you understand the issues.</p>\n"^^ . . "1"^^ . "1"^^ . .

When a button is pressed, it runs a script that triggers a remote event to all clients, saying the button has been pressed, along with the name of the camera as an argument.</p>\n<p>On every client, after recieving this message, this function is ran:</p>\n<pre><code>local function onCameraEvent(cameraName)\n print(&quot;Clicked&quot;)\n for _, child in game.StarterGui.CamerasUI.Cameras:GetChildren() do\n if (child.Name ~= cameraName) then\n child.Visible = false \n\n for _, descendant in pairs(child:GetDescendants()) do\n descendant:Destroy()\n end\n\n end\n end\n\n game.StarterGui.CamerasUI.Cameras[cameraName].Visible = true \n\n\n local cam = Instance.new(&quot;Camera&quot;, game.StarterGui.CamerasUI.Cameras[cameraName])\n cam.Name = &quot;Cam&quot;\n cam.CameraType = Enum.CameraType.Scriptable\n cam.FieldOfView = 70\n\n game.StarterGui.CamerasUI.Cameras[cameraName].CurrentCamera = cam\n \n \n local model = Instance.new(&quot;WorldModel&quot;, game.StarterGui.CamerasUI.Cameras[cameraName])\n model.Name = &quot;World Model&quot;\n \n\n\n for i, minimapObjects in pairs(game.Workspace.Map:GetChildren()) do\n if minimapObjects:IsA(&quot;Sound&quot;) or minimapObjects:IsA(&quot;SoundGroup&quot;) or minimapObjects:IsA(&quot;SoundEffect&quot;) then return end\n minimapObjects:Clone().Parent = model\n end\n local camPart = game.Workspace.Cameras:WaitForChild(cameraName)\n\n\n game[&quot;Run Service&quot;].RenderStepped:Connect(function()\n local camFr = game.Workspace.Cameras[cameraName].CFrame\n cam.CFrame = camFr\n end)\n \nend\n</code></pre>\n<p>Essentially, it finds the SurfaceUI within the starterUI, then enables the viewport frame for the camera who's button was clicked. Also disabling any other viewports that were enabled previously. Then it adds a camera object and a copy of the map to the viewport frame. I did make sure that the viewport frame's &quot;CurrentCamera&quot; property is linked to the newly created camera.</p>\n<p>This creates a copy of the map within the viewport frame, with its camera in the same position as the real physical one would be. The goal is, for the viewport frame to just be an image of what the map looks like from the perspective of whichever camera you clicked on.</p>\n<p><strong>The UI tree looks like this:</strong></p>\n<p>Starter UI &gt; Surface GUI &gt; Folder &gt; Viewport Frame &gt; Camera &amp; Map Model</p>\n<p>(ViewportFrame.CurrentCamera = the camera it parents)</p>\n<p>(SurfaceGUI.adornee = Workspace.randomPartToDisplayCamera)</p>\n<p><strong>Final Question</strong></p>\n<p>After completing all this code, everything looks as if it should function correctly. For example, when I click a button, the correct viewport frame is activated, the map and camera is added to it, and everything looks fine. But, for some reason, no matter what I do, I just can't get the viewport frame to show up on the surface UI. I've tried going and making a separate frame with just one part in it and it works fine, but this just won't show up. Can anyone help me figure this out?</p>\n"^^ .

The first is that I don't fully understand how my script works.\nMy script is simple.\nThe player presses W twice in quick succession to sprint.

"<p>There's deceptively a lot going on here and this is really tougher than it should be... in your original map, <code>:m '&lt;-2&lt;CR&gt;gv=gv</code>, vim is going to basically simulate all these keystrokes similar to a macro. You can press all of them yourself and get the same result. What you will notice in particular is when you have a visual selection and you press <code>:</code>, you will get <code>'&lt;,'&gt;</code> inserted automatically and you will lose the active visual selection. But <code>'&lt;,'&gt;</code> is a <em>range</em> that acts from the <code>'&lt;</code> <em>mark</em> to the <code>'&gt;</code> mark. (These are the &quot;marks&quot; it's referring to in the error message, which we’ll get to later). From <code>:h '&lt;</code> and <code>:h '&gt;</code>:</p>\n<pre><code>'&lt; &lt; To the first line or character of the last selected\n Visual area in the current buffer. For block mode it\n may also be the last character in the first line (to\n be able to define the block).\n\n '&gt; `&gt;\n'&gt; &gt; To the last line or character of the last selected\n Visual area in the current buffer. For block mode it\n may also be the first character of the last line (to\n be able to define the block). Note that 'selection'\n applies, the position may be just after the Visual\n area.\n</code></pre>\n<p>So, we no longer have the visual selection active, but this is precisely what allows that range to work, because it refers to the previous visual selection that was active. Since the area we just had selected is now considered the previous area, it targets the right section. So the desired area will be moved to the line of end of that area plus one. <code>gv=gv</code> will activate the previous visual selection, format it, and then activate the selection again.</p>\n<p>Now that we've explained why the original works, we can move on to fixing your lua version.</p>\n<p>Part of the issue is that neither <code>vim.cmd()</code> nor the <code>&lt;Cmd&gt;</code> part of a keymap simulate the <code>:</code> keystroke in the same way that your regular <code>vnoremap</code> does, but rather they just execute the command. This is the same reason you don't have to manually enter the <code>&lt;CR&gt;</code>. As a result, we don’t get that range automatically added to our <code>m</code> command like we did before, meaning it will only act on the current line by default. This also means that the visual selection won’t get deactivated before the command is executed, so if this is the first selection you’ve made in the buffer, there will be no “previous” selection as you still just have the current one active. I strongly suspect this is why you get the “mark not set” error as the <code>'&lt;</code>/<code>'&gt;</code> have no previous visual selection to hook to yet.</p>\n<p>So, to replicate this behavior using lua commands, we can either simulate the <code>:</code> keystroke properly, work around it by escaping visual mode and using the <code>'&lt;</code> and <code>'&gt;</code> markers manually or by just getting the lines of the visual area while it is still selected and working with those. I'll be showing you how to successfully use the second method in this list and I'll include the code I attempted to get working using the third method as well if you'd like to tinker with it and fix it.</p>\n<p>Simulating the escape keystroke:<br />\nWe'll write a helper function that will simulate the user pressing the escape key so as to leave visual mode.</p>\n<pre class="lang-lua prettyprint-override"><code>local function simulate_escape()\n vim.api.nvim_feedkeys(\n vim.api.nvim_replace_termcodes('&lt;Esc&gt;', true, false, true),\n -- It is essential that you include &quot;x&quot; in this string; without it, the '&lt;\n -- and '&gt; marks won't get updated correctly after &lt;Esc&gt; is simulated.\n 'nx',\n false\n )\nend\n\n</code></pre>\n<p>Next, we'll implement the actual moving:</p>\n<pre class="lang-lua prettyprint-override"><code>local function move_linewise_visual_area(move_up)\n simulate_escape()\n\n if move_up and vim.fn.line(&quot;'&lt;&quot;) &gt; 1 then\n vim.cmd(&quot;'&lt;,'&gt;m '&lt;-2&quot;)\n vim.cmd(&quot;normal gv=gv&quot;)\n elseif not move_up and vim.fn.line(&quot;'&gt;&quot;) &lt; vim.fn.line(&quot;$&quot;) then\n vim.cmd(&quot;'&lt;,'&gt;m '&gt;+1&quot;)\n vim.cmd(&quot;normal gv=gv&quot;)\n else\n vim.cmd('normal gv=gv')\n end\nend\n\n</code></pre>\n<p>This is more or less just replicating the behavior of your original keymap but also checks for start and end of file.</p>\n<p>Now, onto the keymaps. <code>vim.keymap.set</code> should be your go-to function for lua keymaps. It provides a better experience than <code>vim.api.nvim_set_keymap</code> as it has some extras built into it. Once we make that change, then instead of calling <code>'&lt;Cmd&gt;...'</code> in your keymap, you can just replace that string with the actual lua function itself.</p>\n<p>So then your keymap would become</p>\n<pre class="lang-lua prettyprint-override"><code>vim.keymap.set('v', '&lt;C-Up&gt;', function() move_linewise_visual_area(true) end, opts)\nvim.keymap.set('v', '&lt;C-Down&gt;', function() move_linewise_visual_area(false) end, opts)\n</code></pre>\n<p>Note that we have to define a function inline to call the function since we're passing the inner function an argument. Without wrapping it with a function definition, we would just call it once when the init.lua reads it, and it would return a <code>nil</code> to the actual keymap function. If we didn't require an argument to our inner command, we could just pass it <em>without parentheses</em> to achieve the same effect.</p>\n<p>Here's the final result, with the other method I attempted just for reference.</p>\n<pre class="lang-lua prettyprint-override"><code>local opts = { noremap = true, silent = true }\n\nlocal function simulate_escape()\n vim.api.nvim_feedkeys(\n vim.api.nvim_replace_termcodes('&lt;Esc&gt;', true, false, true),\n -- It is essential that you include &quot;x&quot; in this string; without it, the '&lt;\n -- and '&gt; marks won't get updated correctly after &lt;Esc&gt; is simulated.\n 'nx',\n false\n )\nend\n\nlocal function move_linewise_visual_area(move_up)\n simulate_escape()\n\n if move_up and vim.fn.line(&quot;'&lt;&quot;) &gt; 1 then\n vim.cmd(&quot;'&lt;,'&gt;m '&lt;-2&quot;)\n vim.cmd(&quot;normal gv=gv&quot;)\n elseif not move_up and vim.fn.line(&quot;'&gt;&quot;) &lt; vim.fn.line(&quot;$&quot;) then\n vim.cmd(&quot;'&lt;,'&gt;m '&gt;+1&quot;)\n vim.cmd(&quot;normal gv=gv&quot;)\n else\n vim.cmd('normal gv=gv')\n end\nend\n\n-- Key Mappings\nvim.keymap.set('v', '&lt;C-Up&gt;', function() move_linewise_visual_area(true) end, opts)\nvim.keymap.set('v', '&lt;C-Down&gt;', function() move_linewise_visual_area(false) end, opts)\n\n-- Other attempt\n\nlocal function get_visual_area_line_range()\n -- Line that cursor is on (one end of the visual area)\n local cursor_line = vim.fn.line(&quot;.&quot;)\n\n -- Line opposite the cursor's end of the visual area\n local opposite_line = vim.fn.line(&quot;v&quot;)\n\n -- Return the start and end lines of the visual area in that order\n if cursor_line &lt; opposite_line then\n return cursor_line, opposite_line\n else\n return opposite_line, cursor_line\n end\nend\n\nlocal function move_linewise_visual_area_2(move_up)\n local start_line, end_line = get_visual_area_line_range()\n if move_up and start_line &gt; 1 then\n\n vim.cmd(start_line .. &quot;,&quot; .. end_line .. &quot;m &quot; .. start_line - 2)\n vim.cmd(&quot;normal =gv&quot;)\n elseif not move_up and end_line &lt; vim.fn.line(&quot;$&quot;) then\n vim.cmd(start_line .. &quot;,&quot; .. end_line .. &quot;m &quot; .. end_line + 1)\n vim.cmd(&quot;normal =gv&quot;)\n end\nend\n\n\n-- vim.keymap.set('v', '&lt;C-Up&gt;', function() move_linewise_visual_area_2(true) end, opts)\n-- vim.keymap.set('v', '&lt;C-Down&gt;', function() move_linewise_visual_area_2(false) end, opts)\n</code></pre>\n"^^ .

Please be understanding and not too critical of my lack of maths skills.</p>\n<p>The premise is one aircraft will maintain it's course (target) and the other (interceptor) will alter it's course to intercept with the target aircraft at some point in the future.</p>\n<p>The formula/code I made for that is this in lua below (It was based on a simulation page tutorial on calculating lead shots for firing a bullet in an FPS and where it will hit a moving target - obviously that works in an FPS as you intend to only shoot when pointing at a target, but here there is a change of asking for an intercept that can never happen):</p>\n<pre><code> -- Point intercept(Point const &amp;shooter, double bullet_speed, Point const &amp;target, Vector const &amp;target_velocity)\n -- {\n -- double a = bullet_speed*bullet_speed - target_velocity.dot(target_velocity);\n -- double b = -2*target_velocity.dot(target-shooter);\n -- double c = -(target-shooter).dot(target-shooter);\n\n -- return target+largest_root_of_quadratic_equation(a,b,c)*target_velocity;\n -- }\n\n local targetMINUSInterceptor = TVF.VecSubtract(interceptorVec3Point, targetVec3Point)\n local targetVelocityDotProduct = TVF.VecDot(targetVelocityAsVec3, targetVelocityAsVec3)\n\n local a = interceptorSpeedAsNumber * interceptorSpeedAsNumber - targetVelocityDotProduct\n local b = -2 * TVF.VecDot(targetVelocityAsVec3, targetMINUSInterceptor)\n local c = -TVF.VecDot(targetMINUSInterceptor, targetMINUSInterceptor)\n\n local result = TVF.VecAdd(targetVec3Point, (TVF.MultiplyVectorByNumber(targetVelocityAsVec3, TVF.GetLargestRootOfQuadraticEquation(a,b,c))))\n</code></pre>\n<p>Now, that all works perfectly, but only IF both aircraft are travelling in directions and speeds that CAN intercept (even with required turns for the Interceptor).</p>\n<p>However, if you have, for example, the target aircraft heading West, and East of that target you have the Interceptor aircraft heading East (i.e. moving away from each other and already are tail to tail to each other), and allowing for the fact that the interceptor can't go fast enough to catch up and overtake the target aircraft, then the above calculation/formula still gives a position vector, however it's either 'off the map' or in some weird direction and massive magnitude that makes no practical sense.</p>\n<p>I need to know when this calculation (or a modified version of it) gives a possible interception point, and also when it can't give an interception point. This will allow me to make a branching decision in my code to warn the players when an interception is not possible and the target aircraft would have to change it's direction and/or speed and try again.</p>\n<p>Could someone please help? My maths level is very basic trig, so I'd really appreciate it if you could spell it out for me or give me the corrected formula with explanations words for all the terms please.</p>\n"^^ . . .

But, being a flexible language, we can achieve something <em>like</em> classes through clever use of metatables. So let's talk for a moment about how the <code>__index</code> <a href="https://www.lua.org/pil/13.4.1.html" rel="nofollow noreferrer">metamethod</a> works.</p>\n<p>When you ask a table for a key that doesn't exist, it will return <code>nil</code>. But, if you set the <code>__index</code> property to another table, the lookup will fall-through to that table.</p>\n<pre class="lang-lua prettyprint-override"><code>local a = {\n foo = &quot;hello&quot;\n}\nlocal b = {\n bar = &quot;world&quot;\n}\n\n-- ask b for &quot;foo&quot; which isn't defined on 'b'\nprint(b.foo, b.bar) -- returns nil, &quot;world&quot;\n\n-- set the lookup table to 'a'\nsetmetatable(b, { __index = a })\n\n-- ask again for b, which still isn't defined on 'b'\nprint(b.foo, b.bar) -- returns &quot;hello&quot;, &quot;world&quot;\n</code></pre>\n<p>In this example, <code>b</code> did not become a clone of <code>a</code> with all of its properties, it is still a table with only <code>bar</code> defined. If you were to ask for <code>foo</code>, since it does not find it in <code>b</code> it then checks <code>a</code> to see if it can find it there.

"Try ```os.clock()``` and use variables to set or reset your timers depending on the runtime."^^ . "comments"^^ . . . "<p>As I like to quote, &quot;Lua gives you the power, you build the mechanisms&quot;. It is no different for OOP in Lua. This is probably what's leaving you confused.</p>\n<blockquote>\n<p>I want to use real OOP, like for example Java or C# have.</p>\n</blockquote>\n<p>I think this is the first misconception we need to eliminate: Java / C# OOP isn't &quot;real&quot; OOP. It is a particular implementation / variant of OOP called &quot;class-based OOP&quot; which has good language support both in Java and C#. It is as real as Lua's (or JavaScript's, for that matter) prototype-based OOP implementations are, though these tend to leave you more degrees of freedom.</p>\n<p>Let's get started. First, we'll look at some ways to build class-based OOP in terms of metatable-based OOP. For that, we first need to understand what a metatable is.</p>\n<h3>Metatables</h3>\n<p>Consider the following snippet:</p>\n<pre class="lang-lua prettyprint-override"><code>local my_math = {tau = 2 * math.pi}\n...\nprint(my_math.pi) -- oops, nil!\n</code></pre>\n<p>Suppose we want to throw an error if we try to access an absent field. We can't do that, right? Because <code>.</code> is not a normal function. It's built in to the language. We can't change what it does. We could introduce a function, but writing <code>get(my_math, &quot;pi&quot;)</code> or <code>my_math.get&quot;pi&quot;</code> or similar would be pretty verbose. No, we want to keep the concise <code>my_math.pi</code> notation, but we want to change what it does.</p>\n<p>Enter metatables: They let you do just this - change the behavior of <code>t.name</code> (technically, more generally the behavior of <code>t[k]</code>; <code>t.name</code> is just syntactic sugar for <code>t[&quot;name&quot;]</code>).</p>\n<p>When you do <code>t[k]</code>, Lua actually does the following work behind the scenes:</p>\n<ol>\n<li>Look up the value corresponding to key <code>k</code> in <code>t</code>. If this is not <code>nil</code>, <code>t[k]</code> evaluates to this value.</li>\n<li>Otherwise, look up the metatable. If no metatable is set, <code>t[k]</code> evaluates to <code>nil</code>.</li>\n<li>If there is a metatable, and this metatable has an <code>__index</code> field which stores a function <code>f</code>, call <code>t[k]</code> evaluates to <code>f(t, k)</code>. This lets you customize what happens when absent keys are accessed!\nThat's exactly what we want. <code>my_math.tau</code> should do nothing special, it should just give us the value of 2 pi.</li>\n</ol>\n<p>But if and only if we access an absent field - as is the case for <code>my_math.pi</code> - the <code>__index</code> &quot;metamethod&quot; of the metatable of <code>my_math</code> will be called! This lets us throw an error:</p>\n<pre class="lang-lua prettyprint-override"><code>local metatable = {}\nfunction metatable.__index(tab, key)\n error(&quot;no such field. if you're looking for pi, it's not here!&quot;)\nend\nsetmetatable(my_math, metatable)\n</code></pre>\n<p>Now, if you access <code>my_math.pi</code>, you'll get an error. But <code>__index</code> is more powerful than that even. You can return another value. The most frequent use for <code>__index</code> is for &quot;defaults&quot; however, which is why Lua provides language support for this: <code>__index</code> can be a table <code>mt</code>, in which case <code>t[k]</code> evaluates to <code>t[k]</code> if <code>t[k]</code> is not <code>nil</code> and <code>mt[k]</code> otherwise. Consider the following example:</p>\n<pre class="lang-lua prettyprint-override"><code>local defaults = {x = 1}\nlocal t = {y = 2}\nsetmetatable(t, defaults)\nprint(t.x) -- 1, default! without the metatable, this would be nil\nprint(t.y) -- 2\n</code></pre>\n<p><code>__index</code> is not the only metamethod - there are also metamethods for arithmetic, concatenation, comparisons, table length (<code>#</code>), each with their own rules (see the <a href="https://www.lua.org/manual/5.1/manual.html#2.8" rel="nofollow noreferrer">metatable</a> docs in the 5.1 reference manual) - but it is the only one that's really necessary for implementing metatable-based OOP. Some scripting languages, like JavaScript, <em>only</em> have the equivalent of <code>__index</code> (called <code>__prototype__</code> in JS).</p>\n<h3>Some syntactic sugar</h3>\n<p>It's also helpful to be aware of the following frequently used syntactic sugar:</p>\n<ul>\n<li><code>function class:method(...) ... end</code> is equivalent to <code>function class.method(self, ...) ... end</code>: It adds an implicit <code>self</code> as a first parameter. (As my naming suggests, this is frequently used for methods.)</li>\n<li><code>instance:method(...)</code> is roughly equivalent to <code>instance:method(instance, ...)</code>. This is usually used for method calls, passing the object as the first argument (note how this corresponds to the <code>class:method</code> syntactic sugar in the function definition: the <code>instance</code> is passed for <code>self</code>).</li>\n</ul>\n<h3>Your first class</h3>\n<p>Now we can get back to the core of the issue: How can we implement a class? Well, what is an instance, if not a table where absent keys should be looked up as &quot;method&quot; names - as opposed to fields - in the parent (class) table? Since you're interested in gamedev, let's start work on a rudimentary 2d vector class. I will meticulously separate all tables here to make it clear which is which. There are various variants on this. Some variants conflate metatable &amp; class table. Others conflate class table &amp; method table. All of this works, but is not helpful in understanding it.</p>\n<p>First, let's make the tables. They are all closely tied: The methods may need to call constructors or other &quot;static&quot; (using Java terminology) functions, which are stored in the class table. The constructors will need to set the metatable. The metatable needs to have its <code>__index</code> field set to the methodtable, such that accessing <code>instead.method</code> gives us the proper method:</p>\n<pre class="lang-lua prettyprint-override"><code>local vector2d = {} -- &quot;class&quot; table\nlocal methods = {}\nlocal metatable = {__index = methods}\n</code></pre>\n<p>Let's start with the method table. This will be the table behind the <code>__index</code> field in our metatable. Now we can write the constructors.</p>\n<pre class="lang-lua prettyprint-override"><code>function vector2d.new(x, y)\n local instance = {x = x, y = y}\n setmetatable(instance, metatable)\n return instance\nend\nfunction vector2d.new_zero()\n return vector2d.new(0, 0)\nend\n</code></pre>\n<p>Let's have a method to add two vectors, and a method to multiply a vector by a scalar.</p>\n<pre class="lang-lua prettyprint-override"><code>function methods.add(v, w)\n return vector2d.new(v.x + w.x, v.y + w.y)\nend\nfunction methods:multiply(scalar)\n return vector2d.new(self.x * scalar, self.y * scalar)\nend\n</code></pre>\n<p>Et voilà! Your first class! You can now do:</p>\n<pre class="lang-lua prettyprint-override"><code>local v = vector2d.new(1, 2)\nlocal w = vector2d.new(3, 4)\nlocal u = v:add(w):scale(2)\nprint(u.x, u.y) -- 8 12\n</code></pre>\n<p>This is really the fundament of metatable-based (prototype-based) OOP. You can now build on this, adding support for:</p>\n<ul>\n<li>&quot;typeof&quot; checks (just compare <code>getmetatable(instance)</code> against <code>metatable</code>)</li>\n<li>&quot;inheritance&quot; (effectively set the metatable of <code>methods</code> to the parent's <code>methods</code> table) - I'd urge you to consider &quot;composition over inheritance&quot; though;</li>\n<li>operator overloading (just define the respective metamethods in <code>metatable</code>);</li>\n<li>even fancier features like multiple inheritance (prototype-based OOP is more flexible than any class-based OOP systems)</li>\n</ul>\n<p>Note that you get polymorphism &quot;for free&quot; through the metatable, and field access &quot;for free&quot; through the fact that your object is just a table.</p>\n<p>But, this is indeed not the only way to implement OOP. Another popular way is what I call &quot;closure-based OOP&quot;, which has its advantages and disadvantages. Many consider it simpler to understand.</p>\n<h3>Closures</h3>\n<p>Lua has first-class <em>closures</em>: These functions hold references to the variables surrounding them (&quot;upvalues&quot;), allowing them to read &amp; write these &quot;upvalues&quot;. A simple example:</p>\n<pre class="lang-lua prettyprint-override"><code>local foo = 1\nfunction set_foo(x)\n foo = x\nend\nfunction get_foo()\n return foo\nend\nset_foo(2)\nprint(get_foo()) -- 2\n</code></pre>\n<p><code>set_foo</code> can write <code>foo</code>, and <code>get_foo</code> can read it. <code>foo</code> is what I call a &quot;shared&quot; upvalue of <code>set_foo</code> and <code>get_foo</code>: Both could read &amp; write it, and the changes are visible in the respective other closure.</p>\n<p>Closures - and with them, the (fresh) set of upvalues - get created by <code>function</code> definitions. Closures are what allows Lua's lexical scoping to work so seamlessly.</p>\n<p>We can use this to write a vector class using closures. Here's how it looks:</p>\n<pre class="lang-lua prettyprint-override"><code>local vector2d = {}\nfunction vector2d.new(x, y)\n instance = {x = x, y = y} -- you would usually call this &quot;self&quot;\n function instance.add(other_instance)\n return vector2d.new(instance.x + other_instance.x, instance.y + other_instance.y)\n end\n function instance.multiply(scalar)\n return vector2d.new(instance.x * scalar, instance.y * scalar)\n end\n return instance\nend\nfunction vector2d.new_zero()\n return vector2.new(0, 0)\nend\n</code></pre>\n<p>This lets us change the way we call methods; we no longer have to pass the instance, because the methods already know the instance as an upvalue:</p>\n<pre class="lang-lua prettyprint-override"><code>local v = vector2d.new(1, 2)\nlocal w = vector2d.new(3, 4)\nlocal u = v.add(w).scale(2) -- note: . instead of :\nprint(u.x, u.y) -- 8 12\n</code></pre>\n<h3>Comparison</h3>\n<p>I'll let you be the judge which of these two approaches you consider simpler. Since you're still new to Lua, I would recommend starting with that one. After that, learn the other one; you should know both.</p>\n<p>The metatable-based approach shines in terms of performance: You don't need to create many upvalues or closures for each instantiation. It also enables operator overloading further down the road (you will likely want this for vectors, for example). I'd prefer this the more objects and instantiations you expect there to be (for example I would prefer it for vectors, which may be used very frequently).</p>\n<p>Where metatable-based OOP doesn't shine is encapsulation: There are no &quot;private&quot; variables. You can only have &quot;private by convention&quot; table fields. In the closure-based approach, you can use <code>local</code> variables as true private fields only accessible to the set of closures (methods).</p>\n<p>(There are some more nuances, but this is the gist of it.)</p>\n"^^ . . .

Both solutions are equivalent due to the way pandoc constructs filters from global functions if no explicit filter table is returned.</p>\n</li>\n<li><p>The <code>RawInline</code> function does nothing, because <code>return el</code> and <code>return nil</code> do the same thing in this case. Not returning anything from a filter function causes pandoc to keep the object unaltered.

The first capture will then be used to index this table. If the resulting value is <code>nil</code>, no substitution will happen. Otherwise, the entire match will be substituted with the value.</p>\n<p>Using this, you could just write:</p>\n<pre class="lang-lua prettyprint-override"><code>local name_to_colorcode = {\n [&quot;red&quot;] = &quot;#FF0000&quot;,\n [&quot;blue&quot;] = &quot;#4C9FFF&quot;,\n [&quot;purple&quot;] = &quot;#C33AFF&quot;,\n [&quot;green&quot;] = &quot;#53FF4A&quot;,\n [&quot;gray&quot;] = &quot;#E2E2E2&quot;,\n [&quot;black&quot;] = &quot;#000000&quot;,\n [&quot;white&quot;] = &quot;#FFFFFF&quot;,\n [&quot;pink&quot;] = &quot;#FB8DFF&quot;,\n [&quot;orange&quot;] = &quot;#FF8E1C&quot;,\n [&quot;yellow&quot;] = &quot;#FAFF52&quot;,\n -- TODO add more colors\n}\n\nlocal text = &quot;&amp;whiteHello&amp;white World&quot;\nprint(text:gsub(&quot;&amp;([a-z]+)&quot;, name_to_colorcode))\n</code></pre>\n<p>This solution is pretty much <em>strictly better</em> than repeated substitution: It is more performant (linear time O(n) vs O(nm) where m is the number of words in your &quot;map&quot;). And yes, for a map of this size, the difference will be measurable in practice.</p>\n<p>It is also less error-prone; there are no issues with substitutions happening &quot;in the wrong order&quot;. Suppose you had <code>&amp;rose</code> and <code>&amp;rosegold</code>. This one-pass solution would greedily replace <code>&amp;rosegold</code> with the appropriate color code. In the multi-pass replacement solution, you would have to be careful to first replace the longer names, then the prefixes of those.</p>\n<p>That said, it has the limitation of requiring some kind of (implicit) delimiter. I would argue that this is not much of an issue in practice. Most sensible &quot;escape&quot; codes have this - consider for example string (backslash) escape codes or HTML escape codes (&quot;entities&quot;). If your spec requires you to treat <code>&amp;greenhelloworld</code> as <code>#00FF00helloworld</code>, I'd argue that that is quite confusing to tokenize for a human and thus probably a bad idea.</p>\n<p>If you wanted to write an optimally performant single-pass solution, you have two options:</p>\n<ul>\n<li>Use some kind of proper regex engine (Lua patterns are <em>not</em> regex) for Lua. Then you could write a pattern of the form <code>&amp;(red|green|blue|...)</code> and substitute based on that. This is very likely to be more performant. In particular, it can be linear time, where the constant factor is not influenced by how many colors you have.</li>\n<li>Do it yourself, manually, using a trie (prefix tree). This is indeed probably not worth your time.</li>\n</ul>\n<p>If this is the case and you can't change the spec to require color names to be delimited one way or another, you should probably just go with the multi-pass solution until you have demonstrated a performance issue; do not optimize prematurely.</p>\n<blockquote>\n<p>Also, if there's a more efficient way to implement this code, I'd appreciate your input.</p>\n</blockquote>\n<p>Your code has three <em>very minor</em> issues:</p>\n<ul>\n<li>You don't use a capture, so you resort to substringing. This is unnecessary.</li>\n<li>You prepend the <code>#</code> to the strings on-demand, rather than having them pre-prepended in the table.

"Immediately break the loop when condition is not met and go to next line"^^ . . . "watchmaker"^^ . "<p>The point of the <code>&lt;const&gt;</code> local variable attribute is to allow Lua to check, at &quot;load&quot; time (when you call <code>dofile</code> / <code>load</code> / <code>require</code> or similar), whether a local variable is not being mutated - that is, whether the only assignment is the initial one at declaration time. It is a tool to help programmers (1) express intent (2) get slightly more &quot;load time&quot; checking than just syntactic checks.</p>\n<p>This works for <code>local</code> variables precisely because they are local. They are visible only within function scope. This means Lua has all the information it needs when you load a &quot;chunk&quot; of code (effectively a function body) to check whether it abides by the <em>static</em> (load time) rules of <code>&lt;const&gt;</code>.</p>\n<p>&quot;Globals&quot; / &quot;environmental variables&quot; (as I like to call them) are effectively just syntactic sugar for accessing fields in the <code>_ENV</code> (usually <code>_G</code>) table. As such, they are much more dynamic than local variables. You could do <code>_G[some .. complex .. expression] = 42</code>, for example. With global variables, just as with any other table fields, Lua does not have all the information it needs at load time. To begin, it does not even know which fields your code will set or get. Even if it knew this, or limited itself to the <code>&lt;name&gt;</code> syntax, that would still be insufficient. Consider loading a file where a certain global variable that was not set yet is used (perhaps in some callback where the author knows it will be available in time). Lua can not warn about this at the time the file is loaded. (It could, at best, try to warn when the file containing the conflicting constant definitions was loaded, then warn when subsequent files are loaded.)</p>\n<p>As ESkri has said, you can implement run-time checks to guard against accessing constant global variables via a metatable. That could look something like this:</p>\n<pre class="lang-lua prettyprint-override"><code>local constants = {pi = math.pi}\nsetmetatable(_G, {__index = constants, __newindex = function(_, key) error(&quot;attempt to change constant global variable &quot; .. key) end})\nprint(pi) -- runs fine\npi = 3 -- errors\n</code></pre>\n<p>However, this is probably a bad idea:</p>\n<ul>\n<li>It's likely to confuse (future) you as well as whatever static analysis tools you may choose to use. (This could be alleviated to an extent using a different implementation however.)</li>\n<li>It incurs a performance penalty.</li>\n<li>It's still only a runtime check. If you don't hit a code path in your testing, you don't get an error or warning.</li>\n</ul>\n<p>Instead, I would recommend the use of <em>static analysis tools</em> such as <em>Luacheck</em>, which lets you specify [<em>read-only global variables</em> in its <a href="https://luacheck.readthedocs.io/en/stable/config.html" rel="nofollow noreferrer">configuration file</a>, and also supports a <code>new read globals</code> inline option to add read-only global variables, similar to a &quot;constant&quot; definition. Example:</p>\n<pre class="lang-lua prettyprint-override"><code>-- luacheck: globals pi\npi = math.pi\n-- luacheck: new read globals pi\npi = 3\n</code></pre>\n<p>it should be noted that while options are limited in scope to files, the <code>read_global</code> configuration field is per-&quot;project&quot; (folder) you're running Luacheck in. To establish <code>pi</code> as a read-only global project-wide, you could set <code>read_globals = {&quot;pi&quot;}</code>, then use <code>-- luacheck: globals pi</code> to make an exception where <code>pi</code> is defined (followed by <code>-- luacheck: new read globals pi</code> to revoke that exception afterwards).</p>\n"^^ . .

Here's an example:\nX Size {0,10}\nY Size {0,10}.\nThe reason why this won't scale proportional to the screen's size is because I set the size values in <em>pixels</em>, but I have to set it in percentage of the screen's size, so, instead of doing this:\nX Size {0,10}\nY Size {0,10},\nI do this:\nX Size {0.1,0}\nY Size {0.1,0}.\nBy moving my size value to the first number, it will scale according to the screen size.

"<h4>Hash sets in Lua</h4>\n<p>Yes, a table with string keys and truthy values (usually <code>true</code>) is the idiomatic, and most likely most efficient, way to implement a hash set of strings (or numbers, or &quot;pointers&quot; (like functions or tables, which are compared by reference)) in Lua.</p>\n<h4>Method - data name collisions</h4>\n<p>This however:</p>\n<blockquote>\n<pre class="lang-lua prettyprint-override"><code>function dict.contains(self, word) do\n return self[word]\nend\n</code></pre>\n</blockquote>\n<p>is a bad idea, because suddenly <code>dict:contains(&quot;contains&quot;)</code> will be truthy (it will be the <code>contains</code> function).</p>\n<p>Similarly, <code>dict.word</code> will suddenly be truthy as well, even though you probably want all accesses to go through <code>contains</code>.</p>\n<p>I'd recommend just directly doing something like <code>if words[word] then</code> rather than unnecessarily complicating this by forcing it into an OOP style when it is not needed or useful. If you do want this, <em>encapsulate</em> the internal &quot;set&quot; of words, so store it in a field like <code>dict._words</code> to not have the methods conflict with the actual data you're storing.</p>\n<hr />\n<h4>Premature optimization concerns</h4>\n<blockquote>\n<p>Is this option good enough?</p>\n</blockquote>\n<p>It most probably is - <strong>try it and see</strong>. &quot;20k&quot; is a <em>very small number</em> of words for Lua to handle. I see no reason why the first solution shouldn't be <strong>fully satisfying</strong>.</p>\n<p>In asymptotical terms, accessing this table - both to insert new strings, or to get strings - has expected constant time complexity.</p>\n<p>Using the optimized hash table implementation provided by your Lua implementation is most probably a better idea than rolling your own.</p>\n<blockquote>\n<p>Or maybe this one would be better: [...] I am inclining to vote for the 2nd option</p>\n</blockquote>\n<p>So far you have provided no reason why it <em>should</em> be better, and barring exceptional circumstances, I don't think it will be. In many aspects, it's very blatantly worse:</p>\n<ul>\n<li>It's more complex. This complexity would need to be justified.</li>\n<li>It adds overhead. You need your own hashing of strings; you'll be duplicating the work Lua is already doing when it interns strings itself.</li>\n<li>A hashing algorithm written in Lua is very unlikely to outperform the optimized hashing algorithm present in your Lua implementation, especially if you're using a well-optimized one like LuaJIT.</li>\n</ul>\n<blockquote>\n<p>If it is just an address of an interned string, probably the 1st option is quite good one (in terms of memory consumption and better performance)?</p>\n</blockquote>\n<p>Yes, on Lua 5.2 and earlier, <strong>all strings are interned</strong> and there is <strong>no way to turn this off</strong>. What this practically means is that <strong>different strings have different addresses, same strings reuse the same memory</strong>. String comparison is a simple address comparison and thus constant time. This is what enables table access to always be O(1) instead of O(length of string).</p>\n<p>So indeed, on Lua 5.2 and earlier, the first option is most certainly better, and by a lot.</p>\n<p>On Lua 5.3 and later, things get a bit more complicated: Very &quot;long&quot; strings (think thousands of characters) are not interned anymore, but instead are hashed on-demand, meaning comparison for these long strings is O(n), as is table access.</p>\n<p>Now there are two &quot;exceptional circumstances&quot; where the custom hashing <em>could</em> be justified, but I consider it <strong>very unlikely</strong> that you find yourself in either one:</p>\n<ol>\n<li>You're using an older Lua / LuaJIT implementation which does not protect against hash collision attacks, and need to protect against such attacks, which can make table access O(n) and thus lead to denial of service. In this case, custom hashing can help - as does just &quot;salting&quot; the keys with a salt unknown to the attacker.</li>\n<li>With <em>very efficient</em> custom hashing (think implementing a very good hashing algorithm in C, which somehow beats Lua's general-purpose string hashing for your use case), you could potentially beat Lua's built-in hashing. But at that point, you should probably be writing this performance-critical code in C or another language suitable for maximizing performance to begin with.</li>\n</ol>\n<blockquote>\n<p>But from the other side, it should be good for statically defined tables (with interned strings).</p>\n</blockquote>\n<p>If anything, this is another plus point for using Lua's implementation.</p>\n<blockquote>\n<p>While I am going to load keys, maybe the 2nd options is still better?</p>\n</blockquote>\n<p>No.</p>\n<hr />\n<p><strong>TL;DR</strong>: <strong>Don't optimize prematurely</strong>; you'd most likely end up with <strong>more complex, less efficient code</strong>.

Floats use a mantissa-exponent representation. This allows them to represent very big numbers with a loss of precision. Very big or small floats are usually formatted using exponent notation (so something like <code>4.2e+42</code>).</p>\n<p>So on on Lua 5.2 and earlier, you're getting an inaccurate result from your calculation, since the 20!, or even 100! is much larger than the maximum integer a float can accurately represent (2^53), but can still be inaccurately represented.</p>\n<p>Lua 5.3 introduced 64-bit signed integers (*). These overflow silently. Usually they use two's complement. This is what you're seeing here: Your program only uses integers. If you multiply two large integers and the result doesn't fit, it overflows and becomes negative. (The result is correct modulo 2^64, which is often desired).</p>\n<p>Simple example: <code>0xFFFFFFFF*0xFFFFFFFF = -8589934591</code>. <code>0xFFFFFFFF</code> is much smaller than 64-bit, but square it and you get a number which doesn't fit. Lua <em>could</em> theoretically silently &quot;upgrade&quot; to floats in this case, but it doesn't, so float and integer arithmetic behave differently: Integer arithmetic overflows, float arithmetic becomes inaccurate (and may result in infinities for large enough numbers).</p>\n<p>In your particular case, 100! contains at least 50 even factors (2, 4, ..., 100). If we look at the powers of two, we have 2, 4, 8, 16, 32, 64, 128. These contribute 0 + 1 + 2 + 3 + 4 + 5 + 6 additional two's in the product. So we have 100! = 2^(50 + 21) * c where c is some integer. Now what is 2^71 mod 2^64? 0. Hence why you're getting 0.</p>\n<p>This is among the 5.2 / 5.3 incompatibilities: If you try to &quot;just&quot; upgrade, you get integer arithmetic where you had float arithmetic before (division is an exception). This can lead to issues such as this one. To be on the safe side, you could make all numbers floats (append <code>.0</code>). This would work in your program as well.</p>\n<p>If you really want to accurately compute big fibonacci numbers, you will need a big integer library. Lua does not have one built in.</p>\n<p>(*) custom builds of Lua (e.g. for embedded devices) may still use integers or 32-bit floats / 32-bit integers, but by default, you can expect Lua to use 64-bit numbers.</p>\n"^^ .

This means the first byte is just <code>209</code>. <code>a</code> is the string consisting of just the first byte, so <code>&quot;\\209&quot;</code>. Hence, the answer to your question of</p>\n<blockquote>\n<p>I just want to know which symbol would work for the if statement</p>\n</blockquote>\n<p>is just <code>&quot;\\209&quot;</code>. On its own, this is invalid UTF-8: For it to be valid UTF-8, a second byte in a certain range would need to follow. So if your terminal expects UTF-8 and thus can't decode this, it will display the Unicode replacement character to indicate the invalid encoding. Some terminals may try to be clever about guessing the encoding, displaying other characters instead.</p>\n<p>The other conditions you tried didn't work because:</p>\n<ul>\n<li><code>&quot;?&quot;</code> is just the ASCII question mark, equivalent to <code>&quot;\\63&quot;</code>. Obviously, <code>&quot;\\63&quot;</code> is not the same string as <code>&quot;\\209&quot;</code>, since the byte is different. The question mark isn't special in any way.</li>\n<li><code>&quot;�&quot;</code> is just the Unicode replacement character. This is what terminals often render when you give them an invalid codepoint. It is not the &quot;real codepoint&quot;. Under the hood, it is encoded as <code>&quot;\\239\\191\\189&quot;</code>, which is not byte equal to <code>&quot;\\209&quot;</code>.</li>\n<li><code>&quot;&quot;</code> is just the empty string. Being shorter than the one-byte string <code>&quot;\\209&quot;</code>, it can't be equal.</li>\n<li><code>nil</code> won't compare equal to any string, being of a different type.</li>\n</ul>\n<p>In general, keep in mind that Lua strings are just byte strings, not strings of &quot;codepoints&quot; or &quot;grapheme clusters&quot;. If you substring, you're indexing bytes. If you want to index codepoints instead, <a href="https://www.lua.org/manual/5.4/manual.html#pdf-utf8.codepoint" rel="nofollow noreferrer">use the <code>utf8</code> library</a>, and ensure that your strings are UTF-8 encoded.</p>\n"^^ .

The server will give you all the matches you want and maybe a few spurious extras.</p>\n<p>(A common example of this is that if you search for &quot;answers&quot;, the server may include a message that mentions &quot;answer&quot;, because its search engine works on word stems rather than exactly.)</p>\n"^^ .

That works fine. the Object collides with another part that's called Orb and stops in its tracks.

Look for <code>kong-0.11.0-0.rockspec</code> file.</p>\n<pre><code>Step 3: Modify the Dependencies\n</code></pre>\n<p>Once you have located the <code>rockspec</code> file, you can modify the dependencies section to override the version of <code>pgmoon</code>. Open the <code>rockspec</code> file in a text editor and locate the <code>dependencies</code> table. Change the version of <code>pgmoon</code> from <code>1.8.0</code> to <code>1.12.0</code>:</p>\n<p><code>dependencies = { -- ... leafo.pgmoon { version = &quot;1.12.0&quot; }, -- ... }</code></p>\n<pre><code>Step 4: Now Rebuild Kong\n</code></pre>\n<p>After modifying the <code>rockspec</code> file, you need to rebuild Kong. You can do this using <code>LuaRocks</code>:\n<code>luarocks make</code></p>\n<p>This will rebuild the Kong package with the overridden dependency version.</p>\n<pre><code>Step 5: Install the Rebuilt Kong\n</code></pre>\n<p>Finally, you can install the rebuilt Kong package. If you are using a package manager like <code>apt</code> or <code>yum</code>, you will need to remove the existing Kong package before installing the new one. After that, you can install the new Kong package using the package manager.\nAlternatively, if you are not using a package manager, you can install Kong manually by copying the rebuilt package to the appropriate directory. For example, if you are using a Linux system, you can copy the package to <code>/usr/local</code>:\n<code>sudo cp kong-*.tar.gz /usr/local/</code></p>\n<p>Then, extract the package and install Kong:\n<code>sudo tar xzf /usr/local/kong-*.tar.gz -C /usr/local/ sudo ln -s /usr/local/kong/bin/kong /usr/local/bin/</code></p>\n"^^ . . .

There is a button on the screen with the text <code>Place Unit</code>, which for testing purposes is connected to a single model (a noob dummy). The code is supposed to make the model follow the player's mouse in real time and fire a RemoteEvent when the mouse is clicked, placing the unit model on the server side where the user clicked. However, when dragging the mouse to move the model around, it jumps in place and sometimes floats at the camera, only to snap back down and start floating again. This behavior even occurs when the mouse is still. If I click the screen while the unit is mid-jump or mid-float, it is placed in the air. Here's my LocalScript code:</p>\n<pre><code>-- Get unit model from ReplicatedStorage\nlocal unit_name = &quot;Noob&quot;\nlocal unit = game:GetService(&quot;ReplicatedStorage&quot;)[&quot;Unit Models&quot;][unit_name]:Clone()\nunit.Parent = game:GetService(&quot;Workspace&quot;)\n\nlocal offset = 5\ncurrent_position = CFrame.new()\n\nscript.Parent.MouseButton1Click:Connect(function()\n local Mouse = game:GetService(&quot;Players&quot;).LocalPlayer:GetMouse()\n\n local lastMousePosition = Mouse.Hit.Position\n\n -- Update position function\n local function updateTowerPosition()\n local ray = Ray.new(Mouse.UnitRay.Origin, Mouse.UnitRay.Direction * 1000)\n local hitPart, hitPosition = game.Workspace:FindPartOnRay(ray, game.Workspace.Terrain, false, true)\n if hitPosition then\n current_position = CFrame.new(hitPosition) * CFrame.new(0, offset, 0)\n unit:SetPrimaryPartCFrame(current_position)\n end\n end\n\n -- Initial tower placement\n updateTowerPosition()\n\n local render_event\n render_event = game:GetService(&quot;RunService&quot;).RenderStepped:Connect(function()\n local currentMousePosition = Mouse.Hit.Position\n if currentMousePosition ~= lastMousePosition then\n updateTowerPosition()\n lastMousePosition = currentMousePosition\n end\n end)\n\n Mouse.Button1Down:Once(function()\n render_event:Disconnect()\n unit:Destroy()\n game.ReplicatedStorage.Place:FireServer(unit_name, current_position)\n end)\nend)\n</code></pre>\n<p>And here is my server script code that handles the <code>Place</code> RemoteEvent:</p>\n<pre><code>-- Server-side unit placement\ngame:GetService(&quot;ReplicatedStorage&quot;).Place.OnServerEvent:Connect(function(player: Player, unit_name: string, pos: CFrame) \n local unit = game:GetService(&quot;ReplicatedStorage&quot;)[&quot;Unit Models&quot;][unit_name]:Clone()\n unit.Parent = game:GetService(&quot;Workspace&quot;)\n unit.PrimaryPart.CFrame = pos\n unit.PrimaryPart.Anchored = true\nend)\n</code></pre>\n<p>I've attempted to force the tower model to not move while the mouse is still, but it continues to hop and (less frequently) float when moved across certain areas of the screen.

"<p>While having many parts explode and get unanchored will always result in lag because of physics calculations, they are ways to improve the physics performance of your experience.</p>\n<p>Technically, you could just have the parts disappear, it takes away from the player's experience. Even with removing other factors like collision calculations it will suffer because of physics.</p>\n<ol>\n<li><p>One way you can improve the performance of physics is to use <a href="https://create.roblox.com/docs/physics/adaptive-timestepping" rel="nofollow noreferrer">Adaptive Timestepping</a> which improves performance of physics by changing the physics frequency of specific physics calculations.</p>\n<blockquote>\n<p>By default, Roblox simulates physics at 240 Hz. Given cycles of approximately 60 frames per second, around 4 worldsteps are advanced per frame. With adaptive timestepping, the physics engine automatically assigns parts to three &quot;solver islands&quot; by varying their simulation timestep, with an emphasis on 60 Hz for best performance. However, parts that are &quot;harder&quot; to solve will use a faster timestep like 240 Hz to ensure physical stability.</p>\n</blockquote>\n<p>It is also important to note that adaptive timestepping isn't always suitable if you want accuracy on your explosions or physics.</p>\n<blockquote>\n<p>Adaptive timestepping can improve physics performance by up to 2.5 times and it is recommended in most cases. However, some experiences should use Fixed mode (240 Hz), including:</p>\n<p>Experiences that require highly accurate simulations and stability, such as racing games, &quot;destruction&quot; simulations, or games featuring complex mechanisms like tanks.</p>\n</blockquote>\n</li>\n<li><p>Another optimization you can perform is to set the <a href="https://create.roblox.com/docs/reference/engine/classes/Workspace#FallenPartsDestroyHeight" rel="nofollow noreferrer"><code>FallenPartsDestroyHeight</code></a> which dictates how low a part can fall being destroyed. This is especially helpful if they are a lot of parts falling off the map because the parts can be removed sooner resulting in less physics calculations and lag generally.</p>\n<blockquote>\n<p>This property determines the height at which the Roblox engine automatically removes falling BaseParts and their ancestor Models from Workspace by parenting them to nil. This is to prevent parts that have fallen off the map from continuing to fall forever.</p>\n</blockquote>\n</li>\n<li><p>You can properly <a href="https://create.roblox.com/docs/tutorials/environmental-art/assemble-an-asset-library#collisionfidelity" rel="nofollow noreferrer">set Physics and Rendering Parameters</a> for models, parts, and meshes in your experience to improve performace.

While they are more properties that impact performance, those are the most important regarding physics. If you want to learn more why those properties matter towards physics, click the links for the documentation reason why.</p>\n</li>\n<li><p>For larger maps, it may be more suitable to use <a href="https://create.roblox.com/docs/workspace/streaming" rel="nofollow noreferrer">Instance Streaming</a> to only show parts important to the player and not have them need to render some falling parts from across the map.</p>\n<blockquote>\n<p>In-experience instance streaming allows the Roblox engine to dynamically load and unload 3D content and related instances in regions of the world. This can improve the overall player experience in several ways.</p>\n</blockquote>\n</li>\n</ol>\n<p>Essentially what streaming does is only load parts of the in-game world to the player as opposed to the entire world leading to improved performance due to not needing to render as much. Note that this is typically for bigger maps since it does take time to load a new region and if a player fires a rocket into an unloaded region, it leads to some problems.</p>\n<p>For more stuff about optimization I suggest you read <a href="https://create.roblox.com/docs/projects/performance-optimization" rel="nofollow noreferrer">Performance Optimization</a> and <a href="https://create.roblox.com/docs/projects/performance-optimization/computation#physics" rel="nofollow noreferrer">Physic Computation Optimization</a> which gives a very board overview on how to improve performance in your experience.</p>\n<p>The steps I've listed above are very general but provide you good resources on how to improve physics performance without needing to go deeper into your experience to find the root cause such as using the <a href="https://create.roblox.com/docs/studio/microprofiler" rel="nofollow noreferrer">MicroProfiler</a> to find which physics step causes the most lag and which assembly is causing that lag or using the <a href="https://create.roblox.com/docs/studio/developer-console" rel="nofollow noreferrer">Developer Console</a> to visualize which physics are being computed a lot.</p>\n<p>I hope this explanation helps, if you want any questions or issues with my answer, feel free to comment it out and I'll edit my answer as needed or clarify in comments.</p>\n"^^ . .

Using the <code>os</code> library. Then you can use that initiated RNG. In the case of initiatialized seeds in roblox, they are used when creating a new <code>Random</code> object, meaning, if you use multiple you'd have random seeds (or seeding once will not apply the same seed if you instantiate a new one without a seed). As I said, it depends on your use-case, as the topic of seeding random libraries in general can turn into long discussions by themselves. And as said, that is just about seeding.

There is a reference implementation, but there is a variety of implementations and hence probably a variety of memory usage patterns, though I would expect some things to be similar. I'll roughly outline how PUC Lua and LuaJIT would use memory for tables, since these are the most popular implementations.</p>\n<p>Yes, PUC Lua, and LuaJIT, separately store a &quot;list&quot; (&quot;sequence&quot;) part and a &quot;hash&quot; (&quot;mapping&quot;) part. This is necessary to make lists fast and memory-efficient.</p>\n<p>(Beware: The &quot;list&quot; part does not need to store a sequence. It may have holes, for example; only at some point, when it gets too sparse and you add a new entry, will PUC Lua move (part of) it to the hash part when &quot;rehashing&quot;. Similarly, part of a sequence may live in the hash part, until it gets &quot;dense&quot; enough for PUC Lua to move it to the &quot;list&quot; part on the next &quot;rehashing&quot;.)</p>\n<p>A table will use many more machine &quot;words&quot; than just 3. Pointers to the list and sequence parts need to be kept. There's a metatable field. The list and sequence part both have capacities that need to be remembered, etc etc; see the sources for details. All in all, an empty table comes to around at least 56 bytes on my machine.</p>\n<p>Now, when you fill the array or hash part, allocations need to happen for these. There will perhaps be some allocator overhead.</p>\n<p>Allocations for the list part happen in powers of two. This is necessary to make appending items fast (amortized constant time). If tables only used minimal size, you might need to do a linear time reallocation every time you add an element.</p>\n<p>This means, for a 3-item table, Lua will use 4 slots. In PUC Lua, each slot will be a type - value pair. This means two &quot;machine words&quot;, so 16 bytes on a 64-bit machine. On LuaJIT, values are stored more compactly in just 8 bytes using a technique called &quot;NaN boxing&quot;.</p>\n<p>Now, if you use <code>[0] = v</code> in your table, that entry lives in the &quot;hash part&quot; in PUC Lua 5.1. This means a hash part has to be allocated to begin with, and at least 2 slots (4 words) will be needed to store the key-value part alone. All other keys however can live in the array part. In your specific example, the array part can have size exactly two. This means 2 slots (4 words) are saved there. So the two solutions might be comparable in terms of memory usage, though hash part overhead will probably put the former at a disadvantage. Measure using <code>collectgarbage</code> to see for yourself (you need to be careful to either turn off garbage collection, creating no other garbage, or to make sure the tables you are creating for benchmarking purposes are not garbage).</p>\n<p>Now, LuaJIT is special here in that it &quot;wastes&quot; a slot for the 0 key, to make using 0 as performant as not using it, and presumably to not have to subtract 1 when indexing. So on LuaJIT, there is only a minuscule difference between starting at 0 and starting at 1; in fact starting at 0 technically leverages one more slot that would otherwise go unused (but unless your table size is a power of two, this is irrelevant).</p>\n<p>Using keys 4-6 means the entire table will land in the hash part on both PUC and JIT. This means at least 4 additional slots for the keys (the hash part will also use a power of two size). This will use the most memory on both PUC and JIT.</p>\n<blockquote>\n<p>And if they do use only 3 words, how do you find the &quot;starting index&quot; of the &quot;sequence part&quot;, if ipairs won't give it to me?</p>\n</blockquote>\n<p>Well, they don't, so the only way to find this index is by iterating over the entire table to find it (or by knowing it by convention, or storing it in another field, or caching it, etc etc).</p>\n<h3>Closing thoughts</h3>\n<ul>\n<li>When in Rome, do as Romans do. Lua indexing conventionally starts at 1. This is endorsed by the standard library. Simply adhere to this convention, unless you have a really good reason not to.</li>\n<li>Not starting at 1 will also usually have negative performance implications, both in terms of memory usage and time spent accessing keys which live in the hash part.</li>\n<li>Do not optimize prematurely. If you want to optimize memory usage, verify your problem (and optimizations) using <code>collectgarbage(&quot;count&quot;)</code> and potentially <code>collectgarbage(&quot;stop&quot;)</code>. Consider moving data structures to a language like C, or using LuaJIT FFI if necessary.</li>\n</ul>\n"^^ . "1"^^ . . . . . . . . "3"^^ . . . .

I recommend reading it fully to get a good grasp on how to use it. Don't just read the linked package documentation; also read the documentation of the various types and their methods. You may want to familiarize yourself with the <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/invoke/package-summary.html" rel="nofollow noreferrer"><code>java.lang.invoke</code></a> API as well.</p>\n<p>That said, the <em>Foreign Function &amp; Memory</em> (FFM) API provides the <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/StructLayout.html" rel="nofollow noreferrer"><code>StructLayout</code></a> interface for interacting with native structs. Make sure your <code>StructLayout</code> matches the memory layout of the native struct exactly. This includes any padding, as well as using the correct byte alignment and byte order.</p>\n<p>For a simple example, if you have the following C struct:</p>\n<pre class="lang-c prettyprint-override"><code>#include &lt;stdint.h&gt;\n\ntypedef struct Point {\n int32_t x;\n int32_t y;\n} Point;\n</code></pre>\n<p>Then you would want to create a <code>StructLayout</code> like so:</p>\n<pre class="lang-java prettyprint-override"><code>StructLayout pointLayout = MemoryLayout.structLayout(\n ValueLayout.JAVA_INT.withName(&quot;x&quot;),\n ValueLayout.JAVA_INT.withName(&quot;y&quot;),\n).withName(&quot;Point&quot;);\n</code></pre>\n<p>The <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/MemoryLayout.html#structLayout(java.lang.foreign.MemoryLayout...)" rel="nofollow noreferrer"><code>MemoryLayout#structLayout(MemoryLayout...)</code></a> takes a series of <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/MemoryLayout.html" rel="nofollow noreferrer"><code>MemoryLayout</code></a>. This means you can create an arbitrarily complex struct layout, including nested structs. Note calling <code>withName</code> is not actually necessary, but it can help when debugging problems. It can also make some FFM code more readable, such as when acquiring a <code>VarHandle</code> to a region of memory.</p>\n<p>Once you have the <code>StructLayout</code> you can use a <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/SegmentAllocator.html" rel="nofollow noreferrer"><code>SegmentAllocator</code></a> to allocate native memory for the struct from Java. This will give you a <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/MemorySegment.html" rel="nofollow noreferrer"><code>MemorySegment</code></a>.</p>\n<pre class="lang-java prettyprint-override"><code>// 'Arena' is a subtype of 'SegmentAllocator'\ntry (Arena arena = Arena.ofConfined()) {\n MemorySegment pointSegment = arena.allocate(pointLayout);\n // use 'pointSegment'...\n\n} // 'arena' is closed, releasing any memory it allocated\n</code></pre>\n<p>You can call the appropriate <code>get</code> and <code>set</code> methods of <code>MemorySegment</code> with the appropriate arguments to get and set the values of the struct's data members. You would pass this <code>MemorySegment</code> to any downcall <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/invoke/MethodHandle.html" rel="nofollow noreferrer"><code>MethodHandle</code></a> (created via a <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/Linker.html" rel="nofollow noreferrer"><code>Linker</code></a>) that invokes a native function which accepts a <code>Point</code> struct. Similarly, if any such downcall <code>MethodHandle</code> invokes a native function that <em>returns</em> a <code>Point</code> struct then you'll receive a <code>MemorySegment</code>.</p>\n<p>When interacting with native functions, be cognizant of whether or not you're dealing with <em>pointers</em>. That changes how you both create and invoke the downcall <code>MethodHandle</code>. See <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/Linker.html#downcallHandle(java.lang.foreign.FunctionDescriptor,java.lang.foreign.Linker.Option...)" rel="nofollow noreferrer"><code>Linker#downcallHandle(FunctionDescriptor,Option...)</code></a> for more information.</p>\n<hr />\n<h1>Wrapper Java Class</h1>\n<p>Directly using a <code>StructLayout</code> and a <code>MemorySegment</code> at all times is not ideal. You can make it more intuitive by creating a wrapper class that wraps the <code>MemorySegment</code> and exposes getters and setters. This will make interacting with the native struct look just like interacting with a regular Java object. You can also use <a href="https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/lang/foreign/MemoryLayout.html#varHandle(java.lang.foreign.MemoryLayout.PathElement...)" rel="nofollow noreferrer"><code>MemoryLayout#varHandle(PathElement...)</code></a> to make implementing the getters and setters easier.</p>\n<pre class="lang-java prettyprint-override"><code>package com.example;\n\nimport static java.lang.foreign.MemoryLayout.PathElement.groupElement;\nimport static java.lang.foreign.MemoryLayout.structLayout;\nimport static java.lang.foreign.ValueLayout.JAVA_INT;\n\nimport java.lang.foreign.MemorySegment;\nimport java.lang.foreign.SegmentAllocator;\nimport java.lang.foreign.StructLayout;\nimport java.lang.invoke.MethodHandles;\nimport java.lang.invoke.VarHandle;\nimport java.util.Objects;\n\npublic final class Point {\n\n private final MemorySegment segment;\n\n // allocates new memory for a new Point struct (0, 0)\n public Point(SegmentAllocator allocator) {\n this(allocator, 0, 0);\n }\n\n // allocates new memory for a new Point struct (x, y)\n public Point(SegmentAllocator allocator, int x, int y) {\n this(allocator.allocate(LAYOUT));\n setX(x);\n setY(y);\n }\n\n // already allocated Point struct (e.g., from native code)\n public Point(MemorySegment segment) {\n if (segment.byteSize() != LAYOUT.byteSize())\n throw new IllegalArgumentException(&quot;segment's byte size does not match layout's&quot;);\n this.segment = segment;\n }\n\n // Allows passing Point to native functions\n public MemorySegment segment() {\n return segment; // may want to return read-only view?\n }\n\n public int getX() {\n return (int) X.get(segment);\n }\n\n public void setX(int x) {\n X.set(segment, x);\n }\n\n public int getY() {\n return (int) Y.get(segment);\n }\n\n public void setY(int y) {\n Y.set(segment, y);\n }\n\n @Override\n public boolean equals(Object obj) {\n return this == obj || (obj instanceof Point other &amp;&amp; segment.equals(other.segment));\n }\n\n @Override\n public int hashCode() {\n return Objects.hash(Point.class, segment);\n }\n\n @Override\n public String toString() {\n return &quot;Point(x=&quot; + getX() + &quot;, y=&quot; + getY() + &quot;)&quot;;\n }\n\n /* *****************************************************************************\n * *\n * FFM State *\n * *\n *******************************************************************************/\n\n public static final StructLayout LAYOUT;\n\n private static final VarHandle X;\n private static final VarHandle Y;\n\n static {\n LAYOUT = structLayout(JAVA_INT.withName(&quot;x&quot;), JAVA_INT.withName(&quot;y&quot;)).withName(&quot;Point&quot;);\n\n var x = LAYOUT.varHandle(groupElement(&quot;x&quot;));\n X = MethodHandles.insertCoordinates(x, 1, 0L); // bind offset argument to 0\n\n var y = LAYOUT.varHandle(groupElement(&quot;y&quot;));\n Y = MethodHandles.insertCoordinates(y, 1, 0L); // bind offset argument to 0\n }\n}\n</code></pre>\n<p>Also see <a href="https://stackoverflow.com/a/78589925/6395627">my answer</a> to <a href="https://stackoverflow.com/q/78587689/6395627">How can I write an array-like datastructure in Java that takes longs as indices using modern unsafe APIs?</a> for ideas on dealing with native arrays.</p>\n<hr />\n<h1>Executable Example</h1>\n<p>Here is an executable example demonstrating the use of FFM with a C struct.

"<p>I am using the CC:Tweaked Minecraft Mod to attempt to automate crafting of stuff I need a lot of for other mods, and it uses lua. With the particular way the Turtles (robots) work, they need the component items inserted in certain slots in their inventory, set up like the normal crafting grid. To do this I've set up multiple chests around it and wrote a function to tell it what chest it needs to get the item for each slot from. From what I can tell, that part of the function works properly.</p>\n<p>But when I run the program and input the directions of the chest, it then gets stuck on the while loop that's meant to make it wait for the item it needs if it isn't already in the chest, despite the item being there.

"<p>You will want to install two extensions; the <a href="https://marketplace.visualstudio.com/items?itemName=pixelbyte-studios.pixelbyte-love2d" rel="nofollow noreferrer">love2d support</a> extension and the <a href="https://marketplace.visualstudio.com/items?itemName=sumneko.lua" rel="nofollow noreferrer">lua</a> extension so you have the language server which provides syntax highlighting and error checking. Do read their installation instructions.</p>\n<p>This is not enough to complete the setup. To get rid of the undefined 'love' global error, you will want to, in an opened project, do the following:</p>\n<ul>\n<li>open the Visual Studio Code command palette (under the &quot;View&quot; menu)</li>\n<li>Search for &quot;lua addon manager&quot; and open it</li>\n<li>In the lua addon manager you will want to look for LOVE (should be at the top) and enable it.</li>\n</ul>\n<p>This will resolve the undefined global error for this project. If you start a new project, you will need to repeat these steps.</p>\n<p>Worth noting is that there are several versions of Lua that the language server supports; from Lua 5.1 to 5.4 and also LuaJIT. Love2d by default uses LuaJIT for performance reasons. LuaJIT is limited to the Lua 5.1 feature set, so something like the <code>\\\\</code> operator which does an integer division is not supported. When starting a new project it is worth it to check that the Lua extension is configured for LuaJIT so the extension will warn you when you are using unsupported features, which should already be the case if you activated LOVE support as per the above instructions. You can do this by:</p>\n<ul>\n<li>Opening the extensions in the left menu</li>\n<li>Clicking on the gear next to the installed &quot;lua&quot; extension and then clicking &quot;settings&quot;</li>\n<li>In the search box at the top search for &quot;lua runtime version&quot; and make sure &quot;LuaJIT&quot; is selected in the select box.</li>\n</ul>\n<p>Finally most documentation will tell you that you can run your Love2d project from Visual Studio Code using the ALT+L keyboard shortcut. This is likely to conflict with other extensions though. If it doesn't work, you should change the key binding to something like ALT+SHIFT+L. You can do this by taking the following steps:</p>\n<ul>\n<li>Open the visual studio code keyboard shortcuts (under File -&gt; Preferences)</li>\n<li>In the search box at the top, search for &quot;love2d&quot;</li>\n<li>The keyboard shortcut you will want to change is the one named &quot;Run Love2D on the workspace folder&quot;.</li>\n</ul>\n"^^ . .

Here is Handler.lua.</p>\n<pre><code>-- Handler.lua\n\nlocal http = require &quot;resty.http&quot;\nlocal utils = require &quot;kong.tools.utils&quot;\nlocal cjson = require(&quot;cjson&quot;)\n\nlocal MessageForwarder = {\n VERSION = &quot;1.0&quot;,\n PRIORITY = 1000,\n}\n\nlocal function forward_message(conf, request_method, request_path, request_headers, request_body)\n -- Make HTTP Request\n local httpc = http.new()\n local res, err = httpc:request_uri(conf.forward_host .. request_path, {\n method = request_method,\n headers = request_headers,\n body = request_body,\n ssl_verify = false\n })\n\n -- Checking response\n if not res then\n kong.log.err(&quot;Failed to forward request: &quot;, err)\n return kong.response.exit(500)\n end\n\n if res.status ~= 200 then\n kong.log.err(&quot;Responded with status: &quot;,res.status)\n return kong.response.exit(500)\n end\n\n return true -- all is well\nend\n\nlocal function forward_message_new(conf, request_method, request_path, request_headers, request_body)\n local server = assert(socket.bind(&quot;*&quot;, 0))\nend\n\nfunction MessageForwarder:access(conf)\n local request_path = kong.request.get_raw_path()\n local request_method = kong.request.get_method()\n local request_headers = kong.request.get_headers()\n\n local raw_request_body\n if raw_request_method ~= &quot;GET&quot; then\n raw_request_body = kong.request.get_raw_body()\n end\n\n local request_body = cjson.decode(raw_request_body)\n\n local auth_path = conf.auth_token_b2b_endpoint\n\n local bool = forward_message(conf, request_method, request_path, request_headers, request_body)\n\n return true\nend\n\n\nreturn MessageForwarder\n</code></pre>\n<p>The result is always consistent.

The Spring Boot REST API that receives the request forwarded from that plugin returns this error to the Spring Boot log:</p>\n<pre><code>WARN 20440 --- [nio-8010-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Ignoring exception, response committed already: org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message\nWARN 20440 --- [nio-8010-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: I/O error while reading input message]\n</code></pre>\n<p>I'm not sure if the problem is in my Spring Boot API since I've tested it with requests from other sources (Postman, Insomnia, other Spring Boot app, Ajax) and everything works fine, just not from my custom Kong plugin with Lua.

"<blockquote>\n<p>So if I understand this correctly, Lua data types of string, numbers are values, while functions and tables are references.</p>\n</blockquote>\n<p>Since your question is ultimately about implementation details (e.g. memory usage): It is a bit more nuanced than this.</p>\n<p>Lua values are effectively a &quot;tagged union&quot;: There's the type tag, and then there is a value, usually one machine word. For types that don't fit into a single machine word, this value will be a reference, and these types will thus be &quot;reference&quot; types.</p>\n<p><code>nil</code>, booleans, and numbers in Lua are &quot;primitive&quot; types: They are cheap to copy (they use up just a single machine word or less, maybe two machine words together with the type tag, if your Lua implementation does not use <a href="https://piotrduperas.com/posts/nan-boxing/" rel="noreferrer">NaN boxing</a>), so they are copied on every assignment. The value is just the boolean or floating-point number value. <em>Not</em> copying them (referencing them) would be more expensive than copying them.</p>\n<p>Strings <em>behave</em> like a &quot;value&quot; type: They are immutable, so there's no difference between copying and referencing them. But they are implemented as reference types for performance reasons nonetheless. If you assign a string to a variable, the string isn't being &quot;copied&quot; - only the reference (a pointer with a type tag) is being copied.</p>\n<p>This means that when you do <code>local x = ...</code>, you are only using a constant amount of extra memory: The extra memory needed to store one Lua value, which will be around one or two machine words. There is no copy of tables, strings, userdata, threads or functions happening here: All types that aren't trivially copyable are implemented as reference types, mutable or not.</p>\n<blockquote>\n<p>So this should theoretically improve speed by a bit since we're assigning it to a local variable</p>\n</blockquote>\n<p>Indeed it usually does, since it saves you a hash lookup in the global table, but I would recommend against premature optimization nonetheless, especially considering &quot;smart&quot; implementations like LuaJIT.</p>\n<blockquote>\n<p>but I wonder if doing so will consume significantly more memory</p>\n</blockquote>\n<p>Usually not significantly, but you might want to be aware of the following ramifications:</p>\n<ul>\n<li>You need a slot to store this <code>local</code>. (This is only a small constant memory usage and effectively negligible though.)</li>\n<li>If this <code>local</code> is used in functions, it becomes a heap-allocated <em>upvalue</em>. (Again only a small constant usage, no matter how large the value you're referencing or copying is.)</li>\n<li>All functions that use this <code>local</code> will need an &quot;upvalue slot&quot; to reference the upvalue.</li>\n</ul>\n<p>So this is ultimately a time-space tradeoff: If you don't localize, functions have to hit the global table (technically their environment table, which defaults to the global table) to get at global variables. If you localize, you're marrying the function to the values <em>at the time you localize</em>, at a small memory cost (because the function now effectively needs to store a pointer to the upvalue).</p>\n<p>Note also that localizing interferes with monkey-patching: Suppose you do <code>Config = {frobnicate = true}</code>, then load a file which localizes <code>local Config = {}</code>, then another file which redefines <code>Config = {frobnicate = false}</code>. The second file will still work with the outdated definition.</p>\n"^^ . . .

When you bind a function to an event with <code>Connect</code>, you don't have to do much work with arguments in the moment.

More specifically, there's a difference between <code>onDisplayMessage</code> and <code>onDisplayMessage()</code> - the first is a function, and the second is a function <em>call</em>.</p>\n<p>So when Roblox sees this line:</p>\n<pre class="lang-lua prettyprint-override"><code>displayMessageEvent.OnClientEvent:Connect(onDisplayMessage())\n</code></pre>\n<p>It doesn't bind the function <code>onDisplayMessage</code> to the event.

"mouse"^^ . . . "1"^^ . . . . . . "<p>Here's a slightly different perspective. (The answer is still no.)</p>\n<p>Part of the reason that <code>&lt;const&gt;</code> works like it does is because (at least in the standard Lua implementation) it is evaluated purely at compile time. This is very simple to do -- local variables are lexically scoped, and the compiler needs to know about the variable declaration to do anything anyway -- for example it needs to know that it is in fact a local, and whether or not it is an upvalue.</p>\n<p>The VM runtime knows nothing about <code>&lt;const&gt;</code>. The only difference is if the compiler decided to use the information to make some optimization.</p>\n<p>This paradigm doesn't work so well for a theoretical const table feature. We can ask if it is reasonable to expect the compiler to be able to determine whether a table is const (and if so, which fields, or whatever depending on how you implement this feature). In many cases this may be possible through complicated static analysis, but such analysis is probably much more complicated that anything the Lua compiler is currently doing, and you may start running into Halting Problem kinds of issues in more complex edge cases.</p>\n<p>Or, you might invent a way to provide additional information to the compiler that helps it resolve this question. But, if the compiler easily knows which value is a const table, and in what way it is const, I think you have just reinvented strong typing. People have given Lua stronger typing before. It may be an interesting discussion, but it is somewhat of a philosophical departure.</p>\n<p>If you don't do it at compile time, I guess you do it at runtime. This means, you would have some tag or metadata carried with the table object in memory and the VM would check this at runtime. As you know Lua has a flexible user-accessible system that allows this kind of feature -- metatables. Yes, it is true that your suggested syntax may be pretty convenient for your exact use case, but maybe it is not good to use the same syntax for two features that actually work quite differently from each other. (Imagine the question &quot;Why did <code>&lt;const&gt;</code> fail at compile/load time here, but crash at runtime there?&quot;) And I think creative use of the existing features and defining appropriate helper functions may be able to achieve some kind of compromise between syntax convenience, runtime cost, and readability.</p>\n"^^ . . . .

In the posted code <code>x</code> is a (constant) variable to which is bound a table. In that table, <code>a</code> and <code>b</code> are not variables, but they are <em>keys</em>. In Lua a key (or an associative array index) is another value. But remember: values are not variables, rather variables store values. It may help to recall that <code>x.a</code> is just syntactic sugar for <code>x[&quot;a&quot;]</code>, i.e., the table <code>x</code> has a slot indexed by the value <code>&quot;a&quot;</code>. Lua allows the <code>const</code> attribute to be associated with variables, but not values, so <code>a</code> and <code>b</code> cannot be made <code>const</code>.</p>\n<p>There may be some ways to simulate immutable tables using metatable magic, but I suspect that these would come with performance penalties which would defeat <em>one</em> of the reasons for using immutable objects in the first place.

Looking at libvlc_video.h</p>\n<pre class="lang-c prettyprint-override"><code>typedef enum libvlc_video_projection_t\n{\n libvlc_video_projection_rectangular,\n libvlc_video_projection_equirectangular, /**&lt; 360 spherical */\n\n libvlc_video_projection_cubemap_layout_standard = 0x100,\n} libvlc_video_projection_t;\n\ntypedef enum libvlc_video_multiview_t\n{\n libvlc_video_multiview_2d, /**&lt; No stereoscopy: 2D picture. */\n libvlc_video_multiview_stereo_sbs, /**&lt; Side-by-side */\n libvlc_video_multiview_stereo_tb, /**&lt; Top-bottom */\n libvlc_video_multiview_stereo_row, /**&lt; Row sequential */\n libvlc_video_multiview_stereo_col, /**&lt; Column sequential */\n libvlc_video_multiview_stereo_frame, /**&lt; Frame sequential */\n libvlc_video_multiview_stereo_checkerboard, /**&lt; Checkerboard pattern */\n} libvlc_video_multiview_t;\n</code></pre>\n<p>I found that I need to somehow make the <strong>video_multiview</strong> to be <strong>multiview_stereo_sbs</strong> and maybe also <strong>libvlc_video_projection</strong> to <strong>video_projection_rectangular</strong>. I am not so experienced in vlc lua scripting nor how vlc codebase even work. Can someone tell me how to change the thing if at all possible?</p>\n<p>I tried something like</p>\n<pre class="lang-lua prettyprint-override"><code>function activate()\n local input_item = vlc.input.item()\n local name = input_item:name()\n vlc.msg.info(&quot;Activating extension for: &quot; .. name)\n \n if string.match(name, &quot;3dh&quot;) then\n vlc.msg.info(&quot;SBS file detected: &quot; .. name)\n \n -- Attempt to set stereoscopy mode using libvlc_video_multiview_t\n local vout = vlc.object.vout()\n if vout then\n -- set the stereoscopy mode, assuming supported by the VLC and API\n local multiview_mode = 'stereo-sbs' -- translating the C enum to Lua supported string, if exact match required consult API documentation\n \n vlc.var.set(vout, &quot;video-multiview&quot;, multiview_mode)\n -- Assuming libvlc_video_projection_t is properly set for VR mode supported by the libVLC\n local projection_mode = 'equirectangular' -- 360 spherical projection \n\n vlc.var.set(vout, &quot;video-projection&quot;, projection_mode)\n vlc.msg.info(&quot;VR mode enabled for: &quot; .. name)\n else\n vlc.msg.err(&quot;No video output object found&quot;)\n end\n end\nend\n</code></pre>\n<p>but then I got <code>...\\AppData\\Roaming\\vlc\\lua\\extensions\\detectvr.lua:23:VLC lua error in file /builds/videolan/vlc/extras/package/win32/../../../modules/lua/libs/variables.c line 139 (function vlclua_tovalue)</code>.

"0"^^ . . "2"^^ . . . . . . . . . . . "<p>I've been banging my head on this problem for a few days now, and have gotten a bit stuck, so I thought I'd ask here. Would really appreciate any help.</p>\n<h1>Context:</h1>\n<p>The issue that I'm currently facing with my site is that we are getting a lot of nginx 499 errors being raised when clients disconnect before hitting a refresh_token endpoint. (The purpose of this endpoint is to generate a new access token and refresh token from the provided refresh token in the request, and return it to the client). We also block the refresh_token being used to make this request. The problem is, that when the client disconnects, their local storage does not get updated with the new token, and so, the next time they reconnect they are forcibly logged out, as their local storage token is treated as blocked when it hits the refresh_token endpoint the following time.</p>\n<h1>High level solution:</h1>\n<p>What I wanted to do to approach this problem was to essentially catch the 499 error raised by nginx when it occurs, and hit another endpoint on my backend to cache this token. On subsequent hits for this user to the refresh_token endpoint, it can also check if the token exists in the cache, and generate a new one in those cases.</p>\n<h1>The Problem:</h1>\n<p>So, from what I've found, the phase in which I can catch the nginx response status at the end of the request is <a href="https://github.com/openresty/lua-nginx-module?tab=readme-ov-file#log_by_lua" rel="nofollow noreferrer">log_by_lua</a> (specifically in my case, <code>log_by_lua_file</code>). The problem is that <code>log_by_lua_file</code> does not have access to cosocket apis, as per these <a href="https://github.com/openresty/lua-nginx-module?tab=readme-ov-file#cosockets-not-available-everywhere" rel="nofollow noreferrer">docs</a>, and therefore I am unable to make requests to new endpoints with lua scripts here. Now the workaround that the docs recommend is to use <code>ngx.timer.at</code> (Context for the workaround is in the same place as the cosocket apis information docs I linked to previously). I have implemented this workaround using <a href="https://github.com/ledgetech/lua-resty-http" rel="nofollow noreferrer">resty-http</a>, however, am currently getting 404 errors on the endpoint. Is there something I am missing? To be sure that I am using the right endpoint, I also made a curl request from the openresty pod directly to the endpoint, and it worked.

This would construct a CFrame object, which is exactly what PivotTo wants to take in as input. I went a step further and made the noob model have the same rotation as the <code>ogposition</code> part, however you can undo this by creating a CFrame by passing it a Vector3 (which is how Roblox represents 3D vectors for things such as position). and do something like:</p>\n<pre class="lang-lua prettyprint-override"><code>clone:PivotTo(\n CFrame.new(\n ogposition.PrimaryPart.Position + Vector3.new(0, 4 * (i + diffsubs), 0)\n )\n)\n</code></pre>\n"^^ .

For example you could have a <code>GraphemeString</code> &quot;class&quot; which supports (its own version of) <code>s:sub</code>, but operates on graphemes rather than bytes. If you're using the &quot;OOP&quot; style, you could easily swap one for the other.

Initially, in Lua 4.0, there are two forms of for loops: &quot;numical for&quot; and &quot;table for&quot;. The latter matches this question's <code>for key, value in table</code> and is described in <a href="https://www.lua.org/manual/4.0/manual.html#4.4" rel="nofollow noreferrer">https://www.lua.org/manual/4.0/manual.html#4.4</a> as:</p>\n<blockquote>\n<p>The table for statement traverses all pairs (index,value) of a given table. It has the following syntax:</p>\n<pre class="lang-none prettyprint-override"><code>stat ::= for name `,' name in exp1 do block end\n</code></pre>\n<p>A for statement like</p>\n<pre class="lang-none prettyprint-override"><code>for index, value in exp do block end\n</code></pre>\n<p>is equivalent to the code:</p>\n<pre class="lang-none prettyprint-override"><code>do\n local _t = exp\n local index, value = next(t, nil)\n while index do\n block\n index, value = next(t, index)\n end\nend\n</code></pre>\n<p>Note the following:</p>\n<ul>\n<li>_t is an invisible variable. The name is here for explanatory purposes only.</li>\n<li>The behavior is undefined if you assign to index inside the block.</li>\n<li>The behavior is undefined if you change the table _t during the traversal.</li>\n<li>The variables index and value are local to the statement; you cannot use their values after the for ends.</li>\n<li>You can use break to exit a for. If you need the value of index or value, assign them to other variables before breaking.</li>\n<li>The order that table elements are traversed is undefined, even for numerical indices. If you want to traverse indices in numerical order, use a numerical for.</li>\n</ul>\n</blockquote>\n<p>This means that <code>for key, value in table</code> is a special form of the for loop, explicitly for tables, called &quot;table for&quot;, introduced with Lua 4.0. In Lua 5.0, another, more powerful form of for loop was introduced: the &quot;generic for&quot;. It has a different syntax in that it expects an iterator instead of simply a table. (Refer to &quot;generic for&quot; in the Lua 5.0 manual for more information about iterators.)</p>\n<p>As to what happened to &quot;table for&quot;, chapter &quot;Incompatibilities with Previous Versions&quot; in <a href="https://www.lua.org/manual/5.0/manual.html" rel="nofollow noreferrer">https://www.lua.org/manual/5.0/manual.html</a> mentions:</p>\n<blockquote>\n<p>The old construction <code>for k,v in t</code>, where <code>t</code> is a table, is deprecated (although it is still supported). Use <code>for k,v in pairs(t)</code> instead.</p>\n</blockquote>\n<p>So it was deprecated in 5.0 already, but wasn't removed until 5.1 - which, unfortunately, doesn't seem to be to mentioned in the 5.1 manual.</p>\n<p>Finally, according to the code excerpt from the 4.0 manual above, &quot;table for&quot; like <code>for key, value in table</code> did, while it existed, behave like &quot;generic for&quot; with <code>pairs</code> like <code>for key, value in pairs(table)</code> in Lua 5.0 and later.</p>\n"^^ .

I'm trying to follow MobDebug's implementation for setting expression watches, which after removing all the bells and whistles essentially boils down to string-concatenating the expression you want to watch inside a <code>return(...)</code> statement and running that. The exact line is:</p>\n<pre class="lang-lua prettyprint-override"><code>local func, res = mobdebug.loadstring(&quot;return(&quot; .. exp .. &quot;)&quot;)\n</code></pre>\n<p>This works perfectly as long as you're just debugging a single script and most of your variables are just in the global environment, but for my own purposes I'm trying to restrict / scope down the evaluation of these <code>return(...)</code> expressions to certain tables and their fields.</p>\n<p>More specifically, I'm working with some LUA &quot;classes&quot; using the <code>setmetatable / __index</code> pattern, and, given access to the table (let's call it <code>SomeClass</code>) I'd like to be able to evaluate expressions such as</p>\n<pre class="lang-lua prettyprint-override"><code>self.mSomeVariable + self.mSomeOtherVariable - self:someOperation(...)\n</code></pre>\n<p>where <code>self</code> is referring to <code>SomeClass</code> (i.e. there exists <code>SomeClass:someOperation</code>, etc).</p>\n<p>I'm really at my wits end on how to approach this. At first I tried the following, and it most definitely didn't work.</p>\n<pre class="lang-lua prettyprint-override"><code>&gt; SomeClass = {}\n&gt; SomeClass.DebugEval = function(self, chunk_str) return load(&quot;return(&quot; .. chunk_str .. &quot;)&quot;)() end\n&gt; SomeClass.DebugEval(SomeClass, &quot;print(1)&quot;) // 1 nil\n&gt; SomeClass.DebugEval(SomeClass, &quot;print(SomeClass)&quot;) // table: 0000000000CBB5C0 nil\n&gt; SomeClass.DebugEval(SomeClass, &quot;print(self)&quot;) // nil nil\n</code></pre>\n<p>The fact that I cannot even reference the &quot;class&quot; via <code>self</code> by passing it in directly to the wrapping function's argument makes me suspicious that this might be a <code>upvalue</code> problem. That is, <code>load(...)</code> is creating a closure for the execution of this chunk that has no way of reaching the <code>self</code> argument... but why? It's quite literally there???</p>\n<p>In any case, my debugger backend is already on C++, so I thought &quot;no problem, I'll just manually set the <code>upvalue</code>. Again, I tried doing the following using <code>lua_setupvalue</code>, but this also didn't work. I'm getting a runtime error on the <code>pcall</code>.</p>\n<pre class="lang-cpp prettyprint-override"><code>luaL_dostring(L, &quot;SomeClass = {}&quot;); // just for convenience; I could've done this manually\nluaL_loadstring(L, &quot;print(1)&quot;); // [ ... , loadstring_closure ]\nlua_getglobal(L, &quot;SomeClass&quot;); // [ ... , loadstring_closure, reference table]\nlua_setupvalue(L, -2, 1); // [ ... , loadstring_closure] this returns '_ENV'\nlua_pcall(L, 0, 0, 0); // getting LUA_ERRRUN\n</code></pre>\n<p>What am I missing here?

I later looked into the Lua documentation and it clearly confirms that this is the expected behavior</p>\n<blockquote>\n<p>We get all results only when the call is the last (or the only) expression in a list of expressions.</p>\n</blockquote>\n<p><a href="https://www.lua.org/pil/5.1.html" rel="nofollow noreferrer">Source</a></p>\n<p>My question is, why? Is there a reason why the last parameter must be treated differently from all the others? As I'm new to the language, I am interested in understanding the philosophy behind these decisions.</p>\n<p>This question was marked as duplicate, but I don't think the linked post is asking the same question at all. This behavior isn't dependent on a variable number of arguments. Consider this code:</p>\n<pre class="lang-lua prettyprint-override"><code>function foo(a, b, c)\n return a + b + c\nend\nfunction bar()\n return 1, 1\nend\n\nfoo(bar(), 1) -- throws error for trying to add nil\nfoo(1, bar()) -- works as expected\n</code></pre>\n<p>I also don't believe this to be an off-topic question because it seems important to know for when I actually end up using functions that return multiple values. Given the example above, for example, what would be better programming practice if I wanted to take the two values of <code>bar</code> and feed them into the first two arguments of <code>foo</code>?</p>\n"^^ . . . .

Interestingly, if I wrap this code in another <code>pcall</code>, then that outer <code>pcall</code> will behave as expected.</p>\n<p>I generally understand the first two cases, but the last one came as a bit of a surprise to me, so my question is: are the above behaviors well-known (and I have just missed some documentation)? Also, is there anything else I have to watch out for while dealing with SIGINT?</p>\n<p>(I have tried Lua versions 5.4 and 5.3, and they both produce the same result.)</p>\n<p>UPDATE: <a href="https://groups.google.com/g/lua-l/c/mmNZs5Fjt20" rel="nofollow noreferrer">Here</a> is the comment on this issue from Roberto Ierusalimschy.</p>\n"^^ .

Of course, that command is not available on pyright, which causes a pesky error message to appear every time I invoke the command.</p>\n<p>Is there a better way to implement the <code>LspAttach</code> function such that one does not have to detach and reattach servers?</p>\n"^^ . . .

"<p>Your code does a good job setting up a list of waypoints for your enemy to walk along, and you already have the foundation for changing targets. But the logic that decides <em>when</em> to switch waypoints just needs to be a bit smarter.</p>\n<p>So let's walk through the way a knockback along a path should work :</p>\n<div class="s-table-container"><table class="s-table">\n<thead>\n<tr>\n<th>Description</th>\n<th>Diagram</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>Consider the path ABC: <br> - A is the spawn point, and C is the end point, <br> - the distance from A to B is 10 studs, <br> - the distance from B to C is 15.</td>\n<td><a href="https://i.sstatic.net/2fE9v5hM.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/2fE9v5hM.jpg" alt="A simple diagram with three points labelled &quot;A&quot;, &quot;B&quot;, and &quot;C&quot;. There are lines connecting &quot;A&quot; to &quot;B&quot;, and &quot;B&quot; to &quot;C&quot;." /></a></td>\n</tr>\n<tr>\n<td>Let's imagine we have an enemy marching from B to C, and they are 3 studs past B...</td>\n<td><a href="https://i.sstatic.net/Z4usr8lm.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Z4usr8lm.jpg" alt="The same diagram as before, now there is a red dot representing an enemy. It rests along the line between &quot;B&quot; and &quot;C&quot;" /></a></td>\n</tr>\n<tr>\n<td>When the enemy is knocked back 5 studs... <br> - they should be sent back the 3 studs to B, <br> - then the remaining 2 studs should send them towards A.</td>\n<td><a href="https://i.sstatic.net/BHsSVY3z.jpg" rel="nofollow noreferrer"><img src="https://i.sstatic.net/BHsSVY3z.jpg" alt="The enemy dot has been moved onto the line between A and B" /></a></td>\n</tr>\n</tbody>\n</table></div>\n<p>So one way to represent this process is with simple distance calculations. You subtract the distance from the enemy to their last waypoint until the distance to the next waypoint is greater than the remaining knockback, then just place the enemy along the points again.

I used C++ and two open-source libraries to verify the idea above (I don't know Lua). Hopefully you'll be able to convert my code to Lua - it's elementary geometry plus finding a root of a function using <em>bisection</em> method. The code is below:</p>\n<pre><code>#include &lt;cmath&gt;\n#include &lt;iostream&gt;\n\n#include &lt;boost/math/tools/roots.hpp&gt;\n#include &lt;CGAL/Simple_cartesian.h&gt;\n\nnamespace bmt = boost::math::tools;\n\nusing Kernel = CGAL::Simple_cartesian&lt;double&gt;;\nusing Circle = Kernel::Circle_2;\nusing Point = Kernel::Point_2;\nusing Vector = Kernel::Vector_2;\n\n// ------ return vector, corresponding to the point P\nVector toVector(Point const&amp; P)\n{\n return P - CGAL::ORIGIN;\n}\n\n// ------ return unit vector, corresponding to the vector V \nVector unitVector(Vector const&amp; V)\n{\n return V / std::sqrt(V.squared_length());\n}\n\n// ------ return the end point of the vector with origin in (0,0)\nPoint endPoint(Vector const&amp; V)\n{\n return CGAL::ORIGIN + V;\n}\n\n// ------ return the point of intersection of the circle C and its radius, passing through the point P \nPoint boundaryPoint(Circle const&amp; C, Point const&amp; P)\n{\n return C.center() + unitVector(P - C.center()) * std::sqrt(C.squared_radius());\n}\n\n// ------ given points and circle\nPoint const A{30, 30};\nPoint const B{40, 20};\nCircle const C{{50, 50}, 40 * 40};\n\n// ------ computed midpoint and perpendicular unit vector\nauto const M = (toVector(A) + toVector(B)) / 2.0;\nauto const N = unitVector((A - B).perpendicular(CGAL::CLOCKWISE)); \n\n// ------ the root of this function is used to find the center of the circle\ndouble func(double const X)\n{\n auto const D = endPoint(M + X * N);\n return\n (\n std::sqrt(CGAL::squared_distance(C.center(), D))\n +\n std::sqrt(CGAL::squared_distance(A, D))\n -\n std::sqrt(C.squared_radius())\n );\n}\n\n// ------ this function stops the root search when the root is found\nbool tolerance(double const L, double const R)\n{\n return (R - L) &lt;= 0.00001;\n}\n\n// ------ the Boost Math Tools function 'bisect' is used to find the root in the interval [MIN,MAX] \nPoint boundaryPoint(double const MIN, double const MAX)\n{\n auto const t = bmt::bisect(func, MIN, MAX, tolerance);\n auto const D = endPoint(M + t.first * N);\n return boundaryPoint(C, D);\n}\n\nint main()\n{\n auto const T1 = boundaryPoint(-50.0, 0.0);\n std::cout &lt;&lt; T1.x() &lt;&lt; '\\t' &lt;&lt; T1.y() &lt;&lt; std::endl;\n auto const T2 = boundaryPoint(0.0, 50.0);\n std::cout &lt;&lt; T2.x() &lt;&lt; '\\t' &lt;&lt; T2.y() &lt;&lt; std::endl;\n}\n</code></pre>\n<hr />\n<p><strong>Addition #2</strong>. This problem can be solved analytically, that is – without numerical methods. I’ll still use the parametric expression (1) for the point <code>D1</code>. The equation (2) can be elaborated a little bit further. Let’s find a point <code>F</code>, lying on the line, passing through points <code>M</code> and <code>D1</code>, and closest to the center <code>C</code> of the big circle. The vector <code>C-F</code> will be orthogonal to the unit vector <code>N</code>. Some notation:</p>\n<pre><code>a = half-length of the segment (A,B)\nu = length of the segment (C,F)\nv = length of the segment (M,F) \nR = radius of the big circle (= your cr) \n</code></pre>\n<p>The segment <code>(C,T1)</code> is divided by the point <code>D1</code> into two parts - <code>(C,D1)</code> and <code>(D1,T1)</code>. The length of the segment <code>(C,D1)</code> is equal to <code>sqrt(u^2 + (v-t)^2)</code>, and the length of the segment <code>(D1,T1)</code> is equal to the radius of the inscribed circle – that is <code>sqrt(a^2 + t^2)</code>. So, the equation (2) becomes:</p>\n<pre><code> sqrt(a^2 + t^2) + sqrt(u^2 + (v-t)^2) = R\n</code></pre>\n<p>We can try to solve this equation by hand, but it’s not easy. Fortunately, the symbolic algebra website &quot;PolyMathLove.com&quot; can solve it – please see <a href="https://www.polymathlove.com/polymonials/midpoint-of-a-line/symbolic-equation-solving.html#c=solve_algstepsequationsolve&amp;v239=sqrt%2528a%255E2%2Bt%255E2%2529%2Bsqrt%2528u%255E2%2B%2528v-t%2529%255E2%2529%253DR&amp;v240=t" rel="nofollow noreferrer">here</a>.

To do this, you would normally enter command mode from normal mode by pressing <code>:</code>, and then entering the following:</p>\n<pre><code>tag &lt;some_identifier&gt;\n</code></pre>\n<p>To do the same via Lua code in Neovim, you would call <code>vim.cmd</code> with the above as a string argument:</p>\n<pre><code>vim.cmd(&quot;:tag &lt;some_identifier&gt;&quot;)\n</code></pre>\n<p>In your case, you want to use the word under the current cursor position as the identifier to be searched for, thus, the function to be called becomes:</p>\n<pre><code>vim.cmd(&quot;:tag &quot; .. vim.fn.expand(&quot;&lt;cword&gt;&quot;)\n</code></pre>\n<p>Finally, you can map this function to the <code>&lt;leader&gt;-</code> key sequence via the following:</p>\n<pre class="lang-lua prettyprint-override"><code>vim.keymap.set(&quot;n&quot;, &quot;&lt;leader&gt;-&quot;, function()\n vim.cmd(&quot;:tag &quot; .. vim.fn.expand(&quot;&lt;cword&gt;&quot;))\nend, { noremap = true, silent = true })\n</code></pre>\n<p>To address the second question regarding the unexpected symbol, the error comes from the call to <code>loadstring</code>. <code>loadstring</code> takes a chunk, compiles it, and returns a function that can be called to execute the chunk. In parsing the chunk passed in, Lua <em>unexpectedly</em> encounters the angle bracket as it is not apart of the language's syntax, hence the error. The solution is to only pass valid Lua syntax and well-formed strings to <code>loadstring</code>. However, you shouldn't need to use it in Neovim.

However, that module, and so its function, apparently is not automatically part of the <code>telescope</code> table/module.\nSince the <code>builtin</code> module is not accessible from the outside by default, Lua in this instance assumes that <code>builtin</code> in the reference <code>telescope.builtin</code> is a field of the telescope module, which it isn't, resulting in the error <code>&quot;attempt to index **field** 'builtin' (a nil value).&quot;</code></p>\n<p>Now, if you really want to use the <code>require(&quot;some&quot;).module</code> approach, you may add a line to expose <code>builtin</code> as a field of <code>telescope</code> explicitly, like so:</p>\n<pre><code>local telescope = require(&quot;telescope&quot;)\ntelescope.builtin = require(&quot;telescope.builtin&quot;) -- Add this line\n</code></pre>\n<p>Then the line in question would work correctly:</p>\n<pre><code>telescope.builtin.find_files({ cwd = selection.path })\n</code></pre>\n<p>But to avoid ambiguity and unnecessary additions to the <code>telescope</code> namespace, I'd say it’s better to stick with the working version:</p>\n<pre><code>local builtin = require(&quot;telescope.builtin&quot;)\n...\nbuiltin.find_files({ cwd = selection.path })\n</code></pre>\n<p>Finally, I think it was a deliberate intention by the developers of the telescope module to have that structure, as their own <a href="https://github.com/nvim-telescope/telescope.nvim/blob/master/lua/telescope/builtin/init.lua" rel="nofollow noreferrer">code snippets</a> show the <code>require(&quot;some.module&quot;)</code> approach:</p>\n<pre><code>--- To use any of Telescope's default options or any picker-specific options, call your desired picker by passing a lua\n--- table to the picker with all of the options you want to use.

I navigated to love.exe in my install dir, and pulled up its Properties window. Under Compatibility, I clicked 'Change high DPI settings', then enabled 'Override high DPI behaviour' under 'High DPI scaling override', and selected 'Application' on the associated dropdown menu. Applying these settings resolved half of my issue; I'm not longer getting the strange resolution. However, I am now getting my native resolution (1080p), regardless of assigning width and height to 1280 and 720 in conf.lua or by using love.window.setMode() in love.load(). Why does love ignore any resolution I set on fullscreen, and how can I resolve the issue? Thanks in advance, by the way.</p>\n"^^ . "0"^^ . . "0"^^ . "1"^^ . . "Is nested tables okay for you?

However, the issue with <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> not working in insert mode is likely due to terminal settings or conflicts with Neovim's built-in keybindings.</p>\n<h3><strong>Possible Issues &amp; Fixes:</strong></h3>\n<h4><strong>1. Check Terminal Keybindings</strong></h4>\n<p>Some terminals (e.g., Alacritty, Kitty, or even default terminal emulators) might not send <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> correctly. You can check what keys are being sent using:</p>\n<pre class="lang-none prettyprint-override"><code>:imap &lt;C-j&gt;\n:imap &lt;C-k&gt;\n</code></pre>\n<p>If nothing appears, your terminal might be intercepting these keybindings.</p>\n<h4><strong>2. Disable Default <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> Mappings</strong></h4>\n<p>Neovim has built-in behavior for <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> in insert mode (e.g., <code>&lt;C-j&gt;</code> might trigger a snippet expansion in some setups). Try adding this to ensure they work as expected:</p>\n<pre class="lang-lua prettyprint-override"><code>vim.api.nvim_del_keymap('i', '&lt;C-j&gt;')\nvim.api.nvim_del_keymap('i', '&lt;C-k&gt;')\n</code></pre>\n<p>Then reapply your mappings:</p>\n<pre class="lang-lua prettyprint-override"><code>map('i', '&lt;C-h&gt;', '&lt;Left&gt;')\nmap('i', '&lt;C-j&gt;', '&lt;Down&gt;')\nmap('i', '&lt;C-k&gt;', '&lt;Up&gt;')\nmap('i', '&lt;C-l&gt;', '&lt;Right&gt;')\n</code></pre>\n<h4><strong>3. Use <code>vim.keymap.set</code> Instead</strong></h4>\n<p>A more modern way to define key mappings in Neovim is using <code>vim.keymap.set</code>. Try replacing your mapping function with:</p>\n<pre class="lang-lua prettyprint-override"><code>vim.keymap.set('i', '&lt;C-h&gt;', '&lt;Left&gt;', { noremap = true, silent = true })\nvim.keymap.set('i', '&lt;C-j&gt;', '&lt;Down&gt;', { noremap = true, silent = true })\nvim.keymap.set('i', '&lt;C-k&gt;', '&lt;Up&gt;', { noremap = true, silent = true })\nvim.keymap.set('i', '&lt;C-l&gt;', '&lt;Right&gt;', { noremap = true, silent = true })\n</code></pre>\n<h4><strong>4. Debug Terminal Input</strong></h4>\n<p>To ensure your terminal sends the correct keys, run this inside Neovim:</p>\n<pre class="lang-none prettyprint-override"><code>:map &lt;C-j&gt;\n:map &lt;C-k&gt;\n</code></pre>\n<p>If nothing appears, your terminal might not be passing <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> to Neovim.</p>\n<h4><strong>5. Alternative Keybindings</strong></h4>\n<p>If the issue persists, you can try different keybindings that are less likely to be intercepted:</p>\n<pre class="lang-lua prettyprint-override"><code>map('i', '&lt;C-n&gt;', '&lt;Down&gt;') -- Alternative for &lt;C-j&gt;\nmap('i', '&lt;C-p&gt;', '&lt;Up&gt;') -- Alternative for &lt;C-k&gt;\n</code></pre>\n<h4><strong>Conclusion</strong></h4>\n<p>If <code>&lt;C-j&gt;</code> and <code>&lt;C-k&gt;</code> still don’t work:</p>\n<ul>\n<li>Check if your terminal is capturing those keys.</li>\n<li>Try using <code>vim.keymap.set</code> instead of <code>vim.api.nvim_set_keymap</code>.</li>\n<li>Use <code>vim.api.nvim_del_keymap('i', '&lt;C-j&gt;')</code> before remapping.</li>\n<li>Use alternative key combinations like <code>&lt;C-n&gt;</code> and <code>&lt;C-p&gt;</code>.</li>\n</ul>\n"^^ .

Re-initialising the Lua state works and prevents the issue, but I don't really want to be doing that.</p>\n<p>So even doing this breaks:</p>\n<pre><code>local farmList = Environment:GetMapFeatures(&quot;farm&quot;)\nlocal farmTable = LsLua.ConvertToLuaTable(farmList)\nfarmTable = LsLua.ConvertToLuaTable(farmList)\n</code></pre>\n<p>If I don't find a solution, I will probably just change the method so it is not generic, but any help would be greatly appreciated.</p>\n"^^ . . . .

It can either go up, down every 3 mins, and also reset every 24 hrs.\nAlso all 1000 vms need to see the same updated value of signals at the same time.</p>\n<p>Now the ideal way might be to have a separate service (Service B) operating that updates this signal every 3 mins. But the dynamic values are difficult to recreate in any other service, and are not easily exported.</p>\n<p>So to do it in the Service A, I can follow a CAS(Check and Set) pattern, at every VM\nWhere I have a scheduler doing this every 3 mins interval synced to epoch:</p>\n<ol>\n<li>Read the Signals</li>\n<li>Compute updated signals</li>\n<li>Write back new compute Signals</li>\n</ol>\n<p>Now this is inefficient because best case all 1000 Service A vms will be writing back the same value to aerospike, ranging to worst case where I may have</p>\n<ol>\n<li>Write contention(Key busy) due to 1000 concurrent writes</li>\n<li>Different signals being written back due to edge cases of different dynamic values of X and Y in different contexts.</li>\n</ol>\n<p>Thought about using Write policy generation to achieve this where:</p>\n<ol>\n<li>I read all keys, preserve generation of all keys</li>\n<li>Compute all new keys.</li>\n<li>Write all new keys back, with match generation check on write policy</li>\n<li>Raad back final updated key (Is this needed?)</li>\n</ol>\n<p>Looks clumsy, so tried an UDF like this:</p>\n<pre><code>function updateSignal(rec, binName, someParamX, someParamY, hyperParameter, resetFlag)\n if aerospike:exists(rec) then\n local currentSignal = rec[binName]\n local geneneration = record.gen(rec)\n if (someParamX &gt; someParamY) then\n local multiplier = someFunction()\n local updatedSignal = currentSignal * multiplier\n rec[binName] = updatedSignal\n else\n rec[binName] = 1\n end \n aerospike:update(rec)\n else\n aerospike:create(rec)\n rec[binName] = 1\n aerospike:update(rec)\n end\n return rec[binName] -- Return the updated value\nend\n</code></pre>\n<p>Problem is that in the UDF context I don't really have any write gen checking ability, if I don't pass the write gen initially to the UDF.</p>\n<p>Also if I pass the write gen as part of the UDF call, I also need to return back the current value of the signal if the write fails due to gen check(collisions).\nSince I wont have the updated signal once inside the udf context if the record was updated from elsewhere. (Can this even happen? Read somewhere udfs lock the record? is it a Read lock/write lock?)</p>\n<p>Any way around this? Am I missing something?</p>\n"^^ . .

I triggered the location with <code>curl</code> and got what I was hoping for:</p>\n<pre><code>rlott@1022rdnote04:~/testing/MAG-9214/njs-exps$ curl -k https://192.168.56.220/foo\n1741016175.722\nconnect() did not block\nreceive() did not block: data = {&quot;id&quot;:1,&quot;jsonrpc&quot;:&quot;2.0&quot;,&quot;result&quot;:&quot;94e2741e-217f-45c3-902c-4883864fd834&quot;}\n1741016175.723\n</code></pre>\n<p>The main issue with the TCP FIN not and the hang was not <code>lua</code> related but JSON-RPC related.

In order to get the current tile that's highlighted, I take a math.floor() of transformed screen coordinates.\nThe interesting thing is, I only get it to work nicely if I subtract 1 from the returned x game coordinate:</p>\n<pre><code>function Grid:update(dt)\n local constants = Constants()\n local mouse = Mouse()\n local screen = Screen()\n local gameCoord = screen:getGameCoordAt(mouse:getPos())\n local gridCoord = Vec2(math.floor(gameCoord.x) - 1, math.floor(gameCoord.y))\n if gridCoord.x &gt;= 1 and gridCoord.x &lt;= constants.GRID_SIZE then\n self.highlighted = self.grid[gridCoord.x][gridCoord.y]\n end\nend\n</code></pre>\n<p>Example:\n<a href="https://i.sstatic.net/Hbw0P8Oy.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/Hbw0P8Oy.png" alt="enter image description here" /></a></p>\n<p>The origin seems to begin at (2, 1) rather (1, 1). I tried removing the code which adds in the height of the tiles, but it didn't seem to do the trick. Understandably this could be what's causing it since I'm only subtracting the xOffset and yOffset from the screen coord, but not the zOffset, since I don't know what the zOffset of the current tile is.</p>\n<p>So my question is, why? Subtracting 1 from the transformed and floored screen coordinate beautifully matches the current tile's game coordinate but I'm having trouble wrapping my head around the cause.</p>\n<p>Edit:\nI forgot to realize that images in love are drawn in such a way where their position is defined by the left corner of the image. I played around with constant image height tiles to remove the zOffset variability, and when I draw the tiles, I just smidge them to the left by tileWidth/2, so the origin of the game coordinates begins at the &quot;tip&quot; of the isometric diamond:</p>\n<pre><code>function Tile:draw()\n local constants = Constants()\n -- transform the tile's position to isometric coords\n local zOffset = constants.MAX_TILE_HEIGHT - self.image:getHeight()\n\n local iso = Iso(constants.TILE_WIDTH, constants.TILE_HEIGHT)\n local vecIso = iso:transform(self.pos)\n assert(iso:inverse():transform(vecIso).x == self.pos.x)\n assert(iso:inverse():transform(vecIso).y == self.pos.y)\n\n love.graphics.draw(self.image, constants.X_OFFSET + vecIso.x - constants.TILE_WIDTH/2, constants.Y_OFFSET + vecIso.y)\nend\n</code></pre>\n<p>I also added in some asserts to verify the transform is in fact working. Now when hovering over the tip of an isometric tile, it will map neatly the tile's game coordinate:\n<a href="https://i.sstatic.net/TpIi6rTJ.png" rel="nofollow noreferrer"><img src="https://i.sstatic.net/TpIi6rTJ.png" alt="enter image description here" /></a></p>\n<p>Extending further, I was able to get it to work pretty well with images of different heights offsetting the screen coordinate's y position by the difference between the tile height and the max image height:</p>\n<pre><code>function Screen:getGameCoordAt(pos)\n local constants = Constants()\n -- pos is isometric screen cord.\n -- perform inverse transform on pos, and reverse x and y offsets. \n local iso = Iso(constants.TILE_WIDTH, constants.TILE_HEIGHT)\n local transformed = iso:inverse():transform(Vec2(pos.x - constants.X_OFFSET, pos.y - constants.Y_OFFSET - \n constants.MAX_TILE_HEIGHT + constants.TILE_HEIGHT))\n return Vec2(transformed.x, transformed.y)\nend\n</code></pre>\n<p>It's not perfect, but it highlights tiles pretty well. Going forward, it looks like it makes the most sense to use images of fixed height.</p>\n"^^ .

After a bunch of research and some help (mainly gemini and phind) I settled on this amalgamation:</p>\n<pre class="lang-none prettyprint-override"><code>local gShiftPressed = false\nlocal dpiShiftPressed = false\nlocal autoclicking = false    \n\nfunction OnEvent(event, arg)\n  --[[OutputLogMessage(&quot;Event: &quot;..event..&quot; Arg: &quot;..arg..&quot;&quot;)\n  Mouse Button 9 = GShift\n  Mouse Button 6 = DPI Shift--]]\n\n  \n\n \n\n  if (event == &quot;MOUSE_BUTTON_PRESSED&quot;) then\n    if (arg == 9) then\n      gShiftPressed = true\n    elseif (arg == 6) then\n      dpiShiftPressed = true\n    end\n  elseif (event == &quot;MOUSE_BUTTON_RELEASED&quot;) then\n    if (arg == 9) then\n      gShiftPressed = false\n    elseif (arg == 6) then\n      dpiShiftPressed = false\n    end\n  end\n  \n  \n  \n  \n\n  if(gShiftPressed and dpiShiftPressed and not autoclicking) then\n    autoclicking = true\n    while(autoclicking == true) do\n      PressAndReleaseMouseButton(1)\n      if(not gShiftPressed and not dpiShiftPressed) then\n        autoclicking = false\n      end\n    end\n  end\nend\n</code></pre>\n<p>I have 2 problems now:</p>\n<p>1.) LG Ghub says I have a syntax error (I feel like I dont, but who knows)</p>\n<p>2.) When my code was working, it would click continuously but never stop when i wanted it to</p>\n<p>I tried thinking of an async solution, but i dont think Ghub supports Async coding</p>\n"^^ .

They return one <em>tuple</em> that contains multiple things, and you &quot;unpack&quot; the tuple by assigning each of its items to a different variable.</p>\n<pre class="lang-py prettyprint-override"><code>def find(needle: str, haystack:str) -&gt; tuple[int, int]:\n start = 1\n end = 2\n return start, end\n\na, b = find(&quot;hi&quot;, &quot;this&quot;) # a = &quot;hi&quot;; b = &quot;this&quot;\n</code></pre>\n<p>Crucially, this means that all return values are preserved even if you don't unpack.</p>\n<pre><code>a = find(&quot;hi&quot;, &quot;this&quot;) # a = (&quot;hi&quot;, &quot;this&quot;)\n</code></pre>\n<p>Lua doesn't have tuples. Instead of handling multiple-return through tuples, it does so by directly changing the number of returned values based on context. In fact, it's not exactly right to call this &quot;unpacking&quot; at all because there's no tuple to unpack.</p>\n<pre class="lang-lua prettyprint-override"><code>text:find('pollo') --find returns no values\na = text:find('pollo') --find only returns one value - the other gets discarded\na, b = text:find('pollo') --find returns two values\na, b, c = text:find('pollo') --find returns two values and a &quot;padding&quot; nil\n</code></pre>\n<p>Importantly, this is entirely context-dependent. If you change the way your function is called, it returns a different number of arguments.</p>\n<p>The last thing to understand is what <a href="/a/79439772">shingo explained</a>: in both languages, parentheses can only ever contain one value. The difference is that in Lua, one value means one value, but in Python, one value can mean &quot;two values that are actually one value because they're a tuple.&quot;</p>\n<p>So let's look at two code samples: your code and the equivalent in Python.</p>\n<div class="s-table-container"><table class="s-table">\n<thead>\n<tr>\n<th>Lua</th>\n<th>Python</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>a, b = (text:find('pollo'))</code></td>\n<td><code>a, b = (find('pollo', text))</code></td>\n</tr>\n</tbody>\n</table></div>\n<p>In Python, this works fine. The <code>find</code> call returns a tuple containing two values. The parentheses can only contain one value, but that's fine because those two values are in a single tuple. And the <code>a, b</code> unpacks the tuple into two variables.</p>\n<p>But in Lua, the parentheses must contain precisely one value; there's no &quot;cheating&quot; with tuples like in Python. So instead of choosing the two-value return style like it does without parentheses, Lua is forced to choose the one-value return style to make the function fit its context. That makes the line equivalent to <code>a, b = 6</code>, which sets <code>a = 6</code> and <code>b = nil</code>.</p>\n"^^ . . . .

However, I'm facing two issues with this background:</p>\n<p><strong>Problem number one:</strong> I want different layers to move at different speeds to create a parallax effect. Unfortunately, the solution I came up with doesn't work. Here are the relevant fragments of my code:</p>\n<pre><code>-- variables for moving background\nlocal layerOffsets = {}\nlocal layerSpeeds = {\n sky = 100,\n ground = 150,\n clouds = 50,\n}\n\nfunction love.load()\n -- loading libraries\n sti = require 'libraries/sti'\n \n -- loading the background\n map = sti('maps/robot_run_ext.lua')\n\n -- Initialize offsets for each layer\n for layer, _ in pairs(layerSpeeds) do\n layerOffsets[layer] = 0\n end\nend\n\nfunction love.update(dt)\n -- Get the with of the map in pixels\n local mapWidth = map.width * map.tilewidth\n\n -- Update each layer separately\n for layer, speed in pairs(layerSpeeds) do\n layerOffsets[layer] = layerOffsets[layer] - speed * dt\n -- Wrap around when the layer moves off-screen\n if layerOffsets[layer] &lt;= -mapWidth then\n layerOffsets[layer] = 0\n end\n end\nend\n\nfunction love.draw()\n local mapWidth = map.width * map.tilewidth\n\n love.graphics.clear() -- Clear the screen \n\n for layer, offset in pairs(layerOffsets) do\n if map.layers[layer] then\n map.layers[layer]:draw(offset, 0)\n map.layers[layer]:draw(offset + mapWidth, 0)\n end\n end\nend\n</code></pre>\n<p>When I launch the game, <strong>nothing</strong> moves, and I have no idea why. Previously, I tried moving the entire background as a single entity (without separating layers), and everything worked smoothly.</p>\n<p><strong>Problem number two:</strong> The rendering of certain layers appears to be inconsistent and somewhat random. When I first launch the game, everything displays correctly (ground, sky, and clouds are all visible). However, if I close the game and restart it—without changing anything in the code—sometimes the clouds disappear, or parts of the ground aren't visible. Since those ground elements overlap with the sky, I suspect the sky is somehow being drawn on top of them.</p>\n<p>The issue seems to be random: I can run the game five times in a row with everything displaying fine, and then on the next run, some elements suddenly disappear. Again, I <strong>don't</strong> change anything in the code between these launches.</p>\n<p>I've checked that all my libraries are up to date, and everything appears to be in order. I expect the game to render layers consistently and allow them to move at different speeds as intended.</p>\n"^^ . "Why is my string.gsub not working ? (Lua)"^^ . . . . . . "1"^^ . . . . .

"<p>It's a consequence of the way Lua handles <a href="https://www.lua.org/pil/3.3.html" rel="nofollow noreferrer">logical operators</a>. In Lua, <code>a and b</code> is evaluated according to the following logic:</p>\n<ul>\n<li>If <code>a</code> is <code>false</code> or <code>nil</code> (&quot;falsy&quot;), then <code>a</code></li>\n<li>If <code>a</code> is &quot;truthy&quot; (neither of the above), then <code>b</code></li>\n</ul>\n<p><code>a or b</code> is handled similarly - <code>b</code> if <code>a</code> is falsy, <code>a</code> if <code>a</code> is truthy.</p>\n<p>Since <code>and</code> has <a href="https://www.lua.org/pil/3.5.html" rel="nofollow noreferrer">precedence</a> over <code>or</code>, the &quot;ternary&quot; expression is equivalent to <code>(condition and true_value) or false_value</code>. From there, it's probably best to explain its behavior in terms of cases. If <code>condition</code> is <code>true</code>, the and-expression evaluates to <code>true_value</code>, and the or-expression does the same because <code>true_value</code> is truthy. If <code>condition</code> is <code>false</code>, the and-expression evaluates to <code>false</code>, and the or-expression evaluates to <code>false_value</code>. Here's a table for reference:</p>\n<div class="s-table-container"><table class="s-table">\n<thead>\n<tr>\n<th>condition</th>\n<th>condition and true_value</th>\n<th>(condition and true_value) or false_value</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>true</td>\n<td>true_value</td>\n<td>true_value</td>\n</tr>\n<tr>\n<td>false</td>\n<td>false</td>\n<td>false_value</td>\n</tr>\n</tbody>\n</table></div>\n<p>An edge case to watch out for is a falsy (<code>false</code> or <code>nil</code>) <code>true_value</code>. In that case, even if <code>condition</code> is true, <code>condition and true_value</code> evaluates to something falsy, so the or-expression evaluates to <code>false_value</code> instead of <code>true_value</code>. Whether this is a problem depends on your use case. If it's impossible, you're fine. If <code>true_value</code> can be falsy but not <code>false_value</code>, just switch the two and invert the condition. If either can be falsy, you might just want to use an if statement instead.</p>\n"^^ . . . .
