You need to declare `content_scripts` in manifest.json, then [re-inject `content_scripts`](/q/10994324) after reloading/installing the extension in Chrome, but a much simpler solution is to use programmatic injection via `chrome.scripting.executeScript` instead of content_scripts+messaging, see [these examples](/a/67227376).
popup.html: add `defer` to load the script at DOMContentLoaded:
```html
<script src="popup.js" defer></script>
```
popup.js:
```js
(async () => {
const [tab] = await chrome.tabs.query({active: true, currentWindow: true});
const [{result}] = await chrome.scripting.executeScript({
target: {tabId: tab.id},
func: () => document.body.innerText,
});
document.body.textContent = new URL(tab.url).hostname + ': ' +
result.slice(0, 100) + '...';
})();
```
No need for the background script or a separate content script for such simple scraping. |

I have to execute a shell script `log-agent.sh` inside my docker container.
**Dockerfile**
FROM openjdk:11-jre
LABEL org.opencontainers.image.authors="gurucharan.sharma@paytm.com"
# Install AWS CLI
RUN apt-get update && \
apt-get install -y awscli && \
apt-get clean
VOLUME /tmp
ARG JAR_FILE
ARG PROFILE
ADD ${JAR_FILE} app.jar
ENV PROFILE_ENV=${PROFILE}
EXPOSE 8080
COPY entrypoint.sh /
COPY log-agent.sh /
# Set permissions for log-agent.sh
RUN chmod +x /log-agent.sh
# Use entrypoint.sh as the entry point
ENTRYPOINT ["/entrypoint.sh"]
# Execute log-agent.sh
# RUN /bin/bash -c '/logs/log-agent.sh'
CMD ["/bin/bash", "-c", "/log-agent.sh"]
The application startup is successful, but the container is not executing the script. No errors in the logs as well.
Here is what I have already verified:
1. File location.
2. File permissions.
3. Validated the shell script for correctness. (proper shebang operator)
4. Script is executing correctly if executed manually from the container using the docker exec command
Any suggestions? |

### About `I would like it to return tab/sheet name "Park Letter" instead.`
When I saw your showing script, `var sheetName = SpreadsheetApp.getActiveSpreadsheet().getName();` is used as the filename of PDF file at `MailApp.sendEmail (emailAddress, subject ,body, {attachments:[{fileName:sheetName+".pdf", content:contents, mimeType:"application//pdf"}]});`. If you want to use the value of `Park Letter` as the filename of a PDF file, how about the following modification?
By the way, I think that `application//pdf` should be `application/pdf`.
### From:
MailApp.sendEmail (emailAddress, subject ,body, {attachments:[{fileName:sheetName+".pdf", content:contents, mimeType:"application//pdf"}]});
### To:
MailApp.sendEmail(emailAddress, subject, body, { attachments: [{ fileName: "Park Letter" + ".pdf", content: contents, mimeType: "application/pdf" }] });
or
MailApp.sendEmail(emailAddress, subject, body, { attachments: [result.getBlob().setName("Park Letter.pdf")] });
By this modification, the filename of the PDF file is `Park Letter.pdf`.
### About `Even better would be a chosen name or a cell within the sheet.`
If you want to use the filename from the cell value, how about the following modification? In this case, please replace `###` to your sheet name. And, the value of cell "A1" is used as the filename. Please modify it to your actual situation.
### From:
MailApp.sendEmail (emailAddress, subject ,body, {attachments:[{fileName:sheetName+".pdf", content:contents, mimeType:"application//pdf"}]});
### To:
var filename = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("###").getRange("A1").getDisplayValue();
MailApp.sendEmail(emailAddress, subject, body, { attachments: [result.getBlob().setName(`${filename}.pdf`)] });
or
var filename = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("###").getRange("A1").getDisplayValue();
MailApp.sendEmail(emailAddress, subject, body, { attachments: [result.getBlob().setName(`${filename}.pdf`)] });
By this modification, the cell value of "A1" of the sheet "###" is used as the filename of the PDF file.
## Added:
About your following new question.
> Is there a way I can send this same letter to multiple people but as a Bcc from a range? I cannot have anyone seeing another persons email address. The example I am thinking is the same as above but instead of var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Park Letter").getRange("F20"). I was thinking var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("vicki working sheet").getRange("F20:F76") although this would need to be a Bcc. Is such a thing possibe? Thank you so much in advance.
If you want to use the values of `var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("vicki working sheet").getRange("F20:F76")` as `bcc`, how about the following modification?
### From:
MailApp.sendEmail (emailAddress, subject ,body, {attachments:[{fileName:sheetName+".pdf", content:contents, mimeType:"application//pdf"}]});
### To:
var bcc = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("vicki working sheet").getRange("F20:F76").getDisplayValues().flat().join(",");
var filename = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("###").getRange("A1").getDisplayValue();
MailApp.sendEmail(emailAddress, subject, body, { attachments: [result.getBlob().setName(`${filename}.pdf`)], bcc });

A `dplyr` solution:
```
library(dplyr)
df |>
filter(Disease == 1 & lead(Disease) == 2, .by = ID) |>
pull(ID)
```
Result:
```
[1] 2 4
```
**Edit:**
The original question was extended such that cases with disease sequence (1, 3, 2) shall also be included:
```
df |>
filter(Disease == 1 &
(lead(Disease) == 2 |
(lead(Disease) == 3 & lead(Disease, n = 2) == 2)), .by = ID) |>
pull(ID)
```
Result:
```
[1] 2 4 6
```
**Edit 2:**
OP stated in the comments that every sequence (1, 3, 3, 3, ..., 3, 3, 2) shall be allowed, this could be solved like this:
```
library(stringr)
df |>
filter(str_detect(str_c(Disease, collapse = ""), "12|13+2$"), .by = ID) |>
distinct(ID)
```
Result:
```
ID
1 2
2 4
3 6
```

you can make something like this
@Catch(TypeORMError)
export class EntityNotFoundExceptionFilter implements ExceptionFilter {
catch(exception: TypeORMError, host: ArgumentsHost) {
const ctx = host.switchToHttp();
const response = ctx.getResponse<Response>();
const request = ctx.getRequest<Request>();
let status = exception.getStatus();
let message = '';
switch (instanceof exception) {
case InitializedRelationError:
// handle error like
staus = 1;
message = '2';
break;
case AlreadyHasActiveConnectionError:
// handle other error
break;
...
// ATTENTION other exception classes from node_modules/typeorm/errors
...
default:
// handle it like internal server error
status = 500;
message = 'Database exception';
}
response
.status(status)
.json({
statusCode: status,
timestamp: new Date().toISOString(),
path: request.url,
});
}

maybe you must use property value:
foreach (var key in appSettings.AllKeys)
{
Console.WriteLine("Key: {0} Value: {1}", key, appSettings[key].Value);
}
and later, to obtain value you must use:
string result = appSettings[key].Value;
Try and good luck

You should do like this:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
import mysite.wsgi
application = mysite.wsgi.application

I am using Apache 2.4.58 with Windows server 2019 essentials.
I have only 1 server and 1 public IP address with 2 network cards: 192.168.3.100 and 192.168.3.200.
I created 2 proxy directives in httpd-ssl.conf
<VirtualHost _default_:443>
<Proxy "http://192.168.3.100:20300/">
Require expr "(%{HTTP_HOST} == 'domain1.com') || (%{HTTP_HOST} == 'www.domain1.com')"
ProxyPreserveHost On
RequestHeader set X-ProxyBase "/"
</Proxy>
ProxyPass "/" "http://192.168.3.100:20300/"
ProxyPassReverse "/" "192.168.3.100:20300/"
<Proxy "http://192.168.3.200:20600/">
Require expr "(%{HTTP_HOST} == 'domain2.com') || (%{HTTP_HOST} == 'www.domain2.com')"
ProxyPreserveHost On
RequestHeader set X-ProxyBase "/"
</Proxy>
ProxyPass "/" "http://192.168.3.200:20600/"
ProxyPassReverse "/" "192.168.3.200:20600/"
</VirtualHost>
The problem is that only the proxy http://192.168.3.100:20300/ is executed and I can access only domain1.com!
If I try to access domain2.com, I get an error message that the access to the resource is denied.
And if I invert the order of the 2 proxies, it does not matter.
Domain2.com is accessible only if I comment domain1.com proxy.
What can be the problem? |
In my react-native application I use `react-query` to fetch the data from backend written in `Spring Boot`.
```typescript
export function useFetchAllNotes(kindeId: string) {
return useInfiniteQuery<ApiResponseListNote, AxiosError, Response>({
initialPageParam: 0,
queryKey: ['userNotes', {kindeId}],
queryFn: ({pageParam = 0}) => fetchNotesForUser(kindeId, pageParam as number),
getNextPageParam: (lastPage) => {
const currentPage = lastPage.metadata.paging?.page as number;
const totalPages = lastPage.metadata.paging?.totalPages as number;
return currentPage < totalPages - 1
? currentPage + 1
: undefined;
},
select: (data) => {
return {
pages: data.pages.flatMap((page) => page.data ?? []),
pageParams: data.pageParams,
};
}
}
);
}
```
the `spring boot` endpoint looks like this
```kotlin
@GetMapping("/{kindeId}")
fun getUserNotes(
@PageableDefault(sort = ["createdAt"], direction = Sort.Direction.DESC, size = 10)
pageable: Pageable,
@PathVariable kindeId: String
): ApiResponse<List<Note>> = noteService.getAllUserNotes(kindeId, pageable)
```
which returns object with metadata containing pagination object like this
```typescript
export interface ApiResponsePaging {
'totalPages': number;
'totalElements': number;
'page': number;
'pageSize': number;
}
```
all the values above are just values taken from `Pageable` in spring boot, so page indexing starts from 0
And the `FlatList` where the query is used
```typescript
const {
data: notes,
isLoading: isFetchingNotes,
error: fetchingNotesError,
refetch: refetchNotes,
isRefetching: isRefetchingNotes,
hasNextPage,
fetchNextPage,
isFetchingNextPage
} = useFetchAllNotes(kindeId)
const loadMore = () => {
if (hasNextPage) {
fetchNextPage();
}
};
<FlatList
data={notes?.pages ?? [] as Note[]}
renderItem={renderItem}
keyExtractor={(_, index) => index.toString()}
numColumns={1}
onEndReached={({ distanceFromEnd }) => {
if (distanceFromEnd < 0) return;
loadMore()
}}
onEndReachedThreshold={0.1}
initialNumToRender={10}
/>
```
The problem is that when I reach the last page scrolling, then it starts fetching data from 0th page again and again. Do I miss something?

I'm trying to implement basic socket program in C which parses HTTP GET requests for now, in `parse_http_req` function I've declared `char* line;` and after `strncpy` call `line` contains 1st line of HTTP request data. My doubt is I didn't allocate any memory for `line` before I called `strncpy`, how is this code working correctly ? Here is my full `server.c` code (still under development)

If you compile and run server starts at port: `8080` or you can pass desired port as 1st arg like `./server 9000`
To test: `wget http://localhost:8080/dummy/path`
I tried to see if that line strncpy piece of code is valid. Here is my `test.c`
```
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
void f1(char *l2, int size) {
char *l1;
l1 = strncpy(l1, l2, size);
printf("%s\n", l1);
}
void main() {
char *l1= malloc(10);
char *l2 = "test";
strncpy(l1, l2, 5);
printf("%s\n", l1);
free(l1);
f1(l2, 5);
}
```
As I expected if I allocate some memory for `l1` before calling `strncpy` like in main it's all good. But, getting `Segmentation fault (core dumped)` while executing `function f1`. How is similar piece of code working in my `server.c` but not in this `test.c` program
|
how is strncpy able to copy from source to empty destination? |

I am trying to develop a plugin to export markdown file to PDF.
Here is a sample markdown content:
# What is Obsidian ?
Obsidian is a **markdown** editor.
I am using `marked` library to convert `markdown => html string` after which using `html` function of `JSPDF` library to convert to PDF and save
The code snippet is as follows:
```
const pdf = new jsPDF()
//converting markDown text to html

pdf.html(htmlContent, {
callback: (doc) => {
doc.save("output.pdf");
},

});
```
However, the text generated in PDF is poorly formatted as seen below:

If you're writing code where the _only_ difference is a number, or the "number of some fixed thing", then that's a loop, not separate `if` statements, but if you _do_ use if statements, resolve them either with `if` statements that are ordered "largest to smallest match", so there's no fall-through, _or_ with if-else statements, so there's no fall-though. (And based on your question about whether to use a switch: switches operate on static comparison, and your code is based on dynamic comparison, so no, a switch wouldn't work).
However, you don't need either for this. You're doing text matching, so use the best tool in the toolset for that: you can trivially match this pattern with a regex and perform the replace you want, because we're just looking for sequences of `#` at the start of a sentence, followed by one or more spaces, followed by "whatever", and the number of `#` directly correspond to the number in the `<h...>` you want.
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
function convert(doc) {
let lines = doc.split(`\n`);
lines = convertInlineMD(lines);
lines = convertMultiLineMD(lines);
return lines.join(`\n`);
}
function convertInlineMD(lines) {
lines.forEach((line, i) => {
// convert headings
const headingRegex =/^(#+)\s+(.+)/
line = line.replace(headingRegex, (_, h, text) => {
const tag = `h${h.length}`;
return `<${tag}>${text.trim()}</${tag}>`;
});
// convert bold...
// convert italic...
// etc. etc. etc.
lines[i] = line;
});
return lines;
}
function convertMultiLineMD(lines) {
// convert tables, etc. etc.
return lines;
}
// And a simple test based on what you indicated:
const docs = [
`## he#llo\nthere\n# yooo`,
`# he#llo\nthere\n## yooo`
];
docs.forEach((doc,i) => console.log(`[doc ${i+1}]\n`, convert(doc)));

<!-- end snippet -->
However, this is also a naive approach to writing a transpiler, and will be dreadfully inefficient compared to writing a DFA based on the markdown grammar (the "markup language specification" grammar, i.e. the rules that say which tokens can follow which other tokens). |
When you create a custom router in Express using `express.Router()`, parameters won't be passed to it. This means that you can access parameter values only in your main entry file and not in the custom router.
To make parameters accessible in the custom router, you need to instruct Express to pass these parameters using `{ mergeParams: true }` when creating the router, like this:
```js
// customer-router.js
const customRouter = express.Router({ mergeParams: true });
```
This allows parameters to be passed from the main entry file to the custom router, enabling access to them within the router. |

python is consider this \t has the escape sequence .
\t - Indicates the whitespace in python.
for the above case we won't specify any separater .space considered as default separater.

this header.jsx is being called inside the Layout.astro, the issue is whenever i click on my button, toggleVisibility is not being called, but when i initially set the value of open to "True", I am able to see "hello" on my localhost and its hidden when open is initially set to "false" but for some reason my onclick is not working. What might be the possible reason for this? Because there are no errors on the console as well.
thank you |
I am using the pins R package and the `board_gdrive()` function to create a hosted board on my Google Drive. My goal is to have a hosted shiny app that pulls pin data from the Google Drive board. However, it appears that Google Drive requires authentication verification each time. Is there a way to not require, or have the authentication stored with the board so that manual interaction is not required? Here is the code I have been using
```
# Google Drive board
board <- pins::board_gdrive(googledrive::as_id("https://drive.google.com/drive/folders/my-folder-abc123"))
```

I have an Android Studio project with a Kotlin only module in it that I'd like to use to implement database related code (in other words create the database, entities and DAO's) using Jetpack Room.
By reading the [Declaring dependencies](https://developer.android.com/jetpack/androidx/releases/room#declaring_dependencies) documentation, it is explicitly stated that:
> Optionally, for non-Android libraries (i.e. Java or Kotlin only Gradle modules) you can depend on androidx.room:room-common to use Room annotations.
However, I can't compile the project because of errors listed below.
Here's my `build.gradle` file:
```
plugins {
id("java-library")
alias(libs.plugins.jetbrainsKotlinJvm)
alias(libs.plugins.ksp)
}
java {
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
}
ksp {
arg("room.generateKotlin", "true")
}
dependencies {
implementation(libs.room.ktx)
implementation(libs.room.common)
implementation(libs.room.runtime) <-- Needed so I can access `RoomDatabase` abstract class.
ksp(libs.room.compiler)
}
```
Room dependencies in my `libs.versions.toml` file look like this:
```toml
[versions]
// ... other versions
kotlin = "1.9.0"
ksp = "1.9.0-1.0.12"
room = "2.6.1"
jetbrainsKotlinJvm = "1.9.0"
[libraries]
// ... other libs
room-ktx = { group = "androidx.room", name = "room-ktx", version.ref = "room" }
room-common = { group = "androidx.room", name = "room-common", version.ref = "room" }
room-runtime = { group = "androidx.room", name = "room-runtime", version.ref = "room" }
room-compiler = { group = "androidx.room", name = "room-compiler", version.ref = "room" }
#room-testing = { group = "androidx.room", name = "room-testing", version.ref = "room" }
[plugins]
// ...other plugins
ksp = { id = "com.google.devtools.ksp", version.ref = "ksp" }
jetbrainsKotlinJvm = { id = "org.jetbrains.kotlin.jvm", version.ref = "jetbrainsKotlinJvm" }
```
And this is the error I get when I try and sync the project:
```
Could not resolve: androidx.room:room-ktx:2.6.1
Could not resolve: androidx.room:room-runtime:2.6.1
```
My `settings.gradle.kts` is pretty basic, but it's referencing the `google()` repository.
I can't use the Room plugin to configure build options because it can only be ran in an Android module. Honestly, I'm lost. I've no clue why Gradle isn't able to reference those two libraries. |

I have to work with the learning history of a Keras model. This is a basic task, but I've measured the performance of the Python built-in min() function, the numpy.min() function, and the numpy ndarray.min() function for list and ndarray. The performance of the built-in Python min() function is nothing compared to that of Numpy for ndarray (for list performance is almost equal). However, the ndarray.min() function is almost twice as fast as numpy.min(). The ndarray.min() documentation refers to the numpy.amin() documentation, which according to the numpy.amin docs, is an alias for numpy.min(). Therefore, I assumed that numpy.min() and ndarray.min() would have the same performance. However, why is the performance of these functions not equal?
```

If you come across errors such as "SyntaxError: Unexpected token 'export'" or "'SyntaxError: Cannot use import statement outside a module'", along with similar issues, it's necessary to include the module causing the problem in the transpilePackages configuration.
**next.config.mjs or next.config.js**
const nextConfig = {

The below script has been working fine for multiple things but the letter returns as a PDF letter named "Site Utilities" this is the whole spreadsheet name.
I would like it to return tab/sheet name "Park Letter" instead. Even better would be a chosen name or a cell within the sheet.
```
function Email3() {
var ssID = SpreadsheetApp.getActiveSpreadsheet().getId();
var sheetName = SpreadsheetApp.getActiveSpreadsheet().getName();
//var email = Session.getUser().getEmail();
var emailRange = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Park Letter").getRange("F20");
var emailAddress = emailRange.getValue();
var subject = "Coffee Morning";
var body = ("Attached is a letter about the up coming Coffee Morning. \n \nMany thanks, \n \nCoast and Country Parks");
var requestData = {"method": "GET", "headers":{"Authorization":"Bearer "+ScriptApp.getOAuthToken()}};
var shID = getSheetID("Park Letter") //Get Sheet ID of sheet name "Master"
var url = "https://docs.google.com/spreadsheets/d/"+ ssID + "/export?format=pdf&id="+ssID+"&gid="+shID;
var result = UrlFetchApp.fetch(url , requestData);
var contents = result.getContent();
MailApp.sendEmail (emailAddress, subject ,body, {attachments:[{fileName:sheetName+".pdf", content:contents, mimeType:"application//pdf"}]});
};
function getSheetID(name){
var ss = SpreadsheetApp.getActive().getSheetByName(name)
var sheetID = ss.getSheetId().toString()
return sheetID
}
```
I have looked at other examples where it states get sheet name rather than spreadsheet but this didn't seem to work.
I also saw an option for just changing the name "Get New Name". This made sense but I don't think I am putting the code within the right section. |
What would be the best way to solve the problem of wanting to 'auto group' all artboards?
Opposed to dragging a selection box of each artboard, then hitting CMD+G, each page has 8 artboards and I have probably 80-150 pages to get through.
To those proficient in javascript, does this code resemble something workable or should I pack it in?
```
var doc = app.activeDocument;
for (var i = 0; i < doc.artboards.length; i++) {
doc.artboards.setActiveArtboardIndex(i);
var artboard = doc.artboards[i];
var itemsOnArtboard = [];
for (var j = 0; j < doc.pageItems.length; j++) {
var item = doc.pageItems[j];
if (artboard.artboardRect.toString() == item.visibleBounds.toString()) {
itemsOnArtboard.push(item);
}
}
if (itemsOnArtboard.length > 1) {
var group = doc.groupItems.add();
for (var k = 0; k < itemsOnArtboard.length; k++) {
itemsOnArtboard[k].moveToEnd(group);
}
}
}
```
I was expecting Illustrator to cycle through each art board and grouping the contents from each board until it finally reached the last board.
The code seemed to take, beach ball spun for a bit, but no result. |

I want to run a query to produce the following output:
Finished | Faculity | Characteristic | Photo
---------------------------------------------
1 | Math | Good |
0 | Biology | Not Good |
I want to build a query that outputs aformentioned result. But it's not that easy as it seems. From this [simlar question][3], I have tried running the following query:
SELECT flds.id,
(case when flds.name = 'Finished' THEN vals.value END) AS Finished,
(case when flds.name = 'Faculty' THEN vals.value END) AS Faculty,
(case when flds.name = 'Characteristic' THEN vals.value END) AS Characteristic,
(case when flds.name = 'Photo' THEN vals.value END) AS Photo
FROM `values` vals
LEFT JOIN `fields` flds
ON vals.field_id = flds.id
GROUP BY
flds.id,
vals.value;
Which gives me an unexpected result:

I have a problem with writing a dots and boxes game with alpha-beta pruning. The whole program works, but the algorithm makes some stupid moves sometimes and I think it generates wrong evaluation of the state. Could you please look at it and maybe tell me what have I done wrong? I'm completely stuck at it.

I would like to create custom history back and forwards buttons using a React hook.
For reference, in case it helps, I'm trying to replicate the behaviour that can be seen in Spotify's web app. Their custom forwards and back buttons integrate seamlessly with the browser history buttons.
I think I have it mostly working, but with one issue. Here is my React hook:
```javascript
import { useState, useEffect } from 'react';
import { useHistory } from 'react-router-dom';
const useNavigationHistory = () => {
const history = useHistory();
const [length, setLength] = useState(0);
const [direction, setDirection] = useState(null);
const [historyStack, setHistoryStack] = useState([]);
const [futureStack, setFutureStack] = useState([]);
const canGoBack = historyStack.length > 0;
const canGoForward = futureStack.length > 0;
const goBack = () => {
if (canGoBack) {
history.goBack();
}
};
const goForward = () => {
if (canGoForward) {
history.goForward();
}
};
useEffect(() => {
return history.listen((location, action) => {
// if action is PUSH we are going forwards
if (action === 'PUSH') {
setDirection('forwards');
setLength(length + 1);
// add the new location to the historyStack
setHistoryStack([...historyStack, location.pathname]);
// clear the futureStack because it is not possible to go forward from here
setFutureStack([]);
}
// if action is POP we could be going forwards or backwards
else if (action === 'POP') {
// determine if we are going forwards or backwards
if (futureStack.length > 0 && futureStack[futureStack.length - 1] === location.pathname) {
setDirection('forwards');
// if we are going forwards, pop the futureStack and push it onto the historyStack
setHistoryStack([...historyStack, futureStack.pop()]);
setFutureStack(futureStack);
} else {
setDirection('backwards');
// if we are going backwards, pop the historyStack and push it onto the futureStack
setFutureStack([...futureStack, historyStack.pop()]);
setHistoryStack(historyStack);
}
setLength(historyStack.length);
}
});
}, [history, length, historyStack, futureStack]);
return { canGoBack, canGoForward, goBack, goForward };
};
export default useNavigationHistory;
```
In my testing this all seems to work fine when navigating forwards and back between various different pages.
## The Problem
If I navigate forwards by alternating between the same 2 pages, for example:
```
/home
/about
/home
/about
/home
/about
```
...then my logic to determine if we are going forwards or backwards falls apart.
I think it's this line:
```
if (futureStack.length > 0 && futureStack[futureStack.length - 1] === location.pathname) {
```
because the forwards pathname and the backwards pathname are identical, so it thinks I'm going forwards even when I'm going backwards.
I've been trying to figure out how I could resolve this, but haven't managed to get something working.
Is anyone able to help?
Maybe my solution is flawed and I need an entirely different method, I'm not sure. |

A super minimalist solution is to simply assign your variable to another variable that expects to be of type `never` so that your code doesn't compile if a new `job.type` type is added:
```
if (job.type === 'add') {
add(job)
} else if (job.type === 'send') {
send(job)
} else {
const check: never = job
}
```
This has the advantage of being a simple one-liner, but has the disadvantage of not throwing at runtime (if this somehow got compiled) and may result in a linter error for the unused `check` variable. |
hi everyone i'm having problems saving photos from summernote. My project uses springboot jsp. When adding photos to summernote and pressing save, springboot displays the error "Maximum upload size exceeded". Local image size is 8MB.I tried to configure image size but it didn't work. When you add an image using the file type input box, it is saved normally. Hope to receive help from others. Thanks a lot!

1. Return a pointer to the `Node` of interest instead of updating the out parameter `head_dest`. The stack will implicitly hold `cur_list_dest`.
1. The original implementation changes the original list. To create a new list you need to return a pointer to *copy* of the smallest node or NULL. To emphasize that I made the argument constant with `const Node *head`.
1. Observe that `pairWiseMinimumInNewList_Rec()` either returns a copy of 1st node, 2nd node or NULL (3 values). The recursive call is either two nodes head or NULL (2 values). For at most 6 cases. If you make the values conditional instead of expressions you can collapse that into a single return statement.

My program uses orthpgraphic projection with an internal resolution of 480x270 and a viewport resolution of 1920x1080 (without shaders). When I draw a rectangle directly to the framebuffer I am able to move it around in incriments of 0.25 pixels (because there are 4 pixels in the framebuffer for every 1 pixel of internal resolution). But when I switch from drawing directly to the framebuffer to redering to a 1920x1080 FBO texture, instead of the 0.25 pixel movements, it "snaps" and only moves 1 whole pixel at a time. Why is this? |

I am making a program that solves a sudoku game, but I received an error from my compiler.
```
error: invalid use of undefined type ‘struct Square’
30 | if(box->squares[x]->possible[number-1] == 0){
^~
```
the function is:
```
int updateBoxes(Square *** sudoku, int row, int column){
int x;
int number = sudoku[row][column]->number;
Box * box;
box = sudoku[row][column]->box;
for(x = 0; x < SIZE_ROWS; x++){
if(box->squares[x]->possible[number-1] == 0){
box->squares[x]->solvable--;
box->squares[x]->possible[number-1] = 1;
}
}
return 1;
}
```
the error also aplies to the next two lines.
the definitions of `Square` and `Box` are:
```
typedef struct box
{
struct Square ** squares; /* array of Squares */
int numbers;
int possible[9];
int solvable;
struct Box * next;
} Box;
/* square is a single number in the board */
typedef struct square
{
int number;
int possible[9];
/*
the array is only made of 0 and 1
each index corresponds to a number: ex: index 4 == number 5 ...
1 tells me that 5 cannot go into this scare
0 tells me that 5 can go into this scare
*/
int solvable; /* will be subtracted 1 each time and when it is 1 it's because is solvable */
Box * box; /* tells me the corresponding box */
int row;
int column;
} Square;

```Because when I use the stored procedure in Crystal Report, it does not work because to create the columns it requires me to put the start and end dates, which is a variable that cannot be fixed.```
Does this mean you think the values you assign during selecting the procedure is fixed and cant be changed after design?
values to stored procedure can be changed dynamically even after designing.
I add Stored procedure like this.
select Database expert > select the correct connection > select Db > select schema > select stored procedure > select required procedure > click right single arrow > it'll ask values for stored procedure variable.
The values assigned here is used only to show the columns for designing purpose.
You can give different values for this parameters even after designing. Can give different values in each Run. |

Yes if you are creating the program on the browser using html and js, you can use the following code to achieve it. By changing the template inside `amountInput.oninput` you can change the maximum amount.
HTML
<label>Montant Rechargement</label>
<br />
<input
autocomplete="cc-number"
id="amountInput"
name="amountInput"
type="tel"
placeholder="1 000 000"
/>
JS
const amountInput = document.getElementById("amountInput");
amountInput.oninput = (e) => {
let cursorPos = e.target.selectionStart
let currentValue = e.target.value
let cleanValue = currentValue.replace(/\D/g, "");
let formatInput = patternMatch({
input: cleanValue,
template: "x xxx xxx xxx"
});
e.target.value = formatInput
let isBackspace = (e?.data==null) ? true: false
let nextCusPos = nextDigit(formatInput, cursorPos, isBackspace)
amountInput.setSelectionRange(nextCusPos+1, nextCusPos+1);
};
function nextDigit(input, cursorpos, isBackspace) {
if (isBackspace){
for (let i = cursorpos-1; i > 0; i--) {
if(/\d/.test(input[i])){
return i
}
}
}else{
for (let i = cursorpos-1; i < input.length; i++) {
if(/\d/.test(input[i])){

I have a DataGridView containing data about different customers, and my objective is to print each row on a separate page. However, I'm facing a problem where the data from two consecutive rows prints on the same page, overlapping each other. For example, if I have four rows in my DataGridView, the content of rows 1 and 2 prints on the same page, and similarly for rows 3 and 4.
Below is the relevant code snippet where I handle the printing logic:
```
private int currentRow = 0;
private void printDocument2_PrintPage(object sender, PrintPageEventArgs e)
{
string companyName = "چوہان ڈیری فارمز"; // Your company name
DateTime startDate = dtm_start.Value;
DateTime endDate = dtm_end.Value;
// Set font and brush for drawing
Font headingfont = new Font("Times New Roman", 18, FontStyle.Bold);
Font font = new Font("Times New Roman", 13, FontStyle.Regular);
Font linefont = new Font("Jameel Noori Nastaleeq", 12, FontStyle.Regular);
Font infofont = new Font("Times New Roman", 11, FontStyle.Regular);
Font nofont = new Font("Jameel Noori Nastaleeq", 9, FontStyle.Regular);
Brush brush = Brushes.Black;
Pen pen = new Pen(Color.Black, 2);
// Calculate the width and height of the page
float pageWidth = e.PageBounds.Width;
float pageHeight = e.PageBounds.Height;
// Measure the size of the text
SizeF textSize = e.Graphics.MeasureString(companyName, headingfont);
// Calculate X coordinate to center the text
float x = (pageWidth - textSize.Width) / 2;
int xAxis = 190;
if(currentRow<dataGridView2.Rows.Count)
{
DataGridViewRow row = dataGridView2.Rows[currentRow];
e.Graphics.DrawString(companyName, headingfont, brush, x, 17); // Adjust the Y coordinate as needed
e.Graphics.DrawString("--------------------------------------------", linefont, brush, 20, 30); // Adjust the Y coordinate as needed
e.Graphics.DrawString(":اکاؤنٹ نمبر", font, brush, xAxis, 60);
e.Graphics.DrawString(":نام", font, brush, xAxis, 90);
e.Graphics.DrawString("--------------------------------------------", linefont, brush, 20, 100);
e.Graphics.DrawString(":تاریخ", font, brush, 225, 125);
e.Graphics.DrawString("--------------------------------------------", linefont, brush, 20, 140);
e.Graphics.DrawString(":سابقہ بیلنس", font, brush, xAxis, 170);
e.Graphics.DrawString(":ٹوٹل لیٹر", font, brush, xAxis, 200);
e.Graphics.DrawString(":دودھ رقم", font, brush, xAxis, 230);
e.Graphics.DrawString(":پرچی رقم", font, brush, xAxis, 260);
e.Graphics.DrawString(":بیلنس", font, brush, xAxis, 290);
//e.Graphics.DrawString(startDate.Date.ToString(), font, brush, 160, 130);
if (row.Cells["Id"].Value != null)
e.Graphics.DrawString(row.Cells["Id"].Value.ToString(), font, brush, 150, 60);
if (row.Cells["Customer Name"].Value != null)
e.Graphics.DrawString(row.Cells["Customer Name"].Value.ToString(), font, brush, 70, 90);
if (row.Cells["Previous Balance"].Value != null)
e.Graphics.DrawString(row.Cells["Previous Balance"].Value.ToString(), font, brush, 70, 170);
// write status in urdu for previous balance
if (row.Cells["pStatus"].Value != null)
{
string pStatus = row.Cells["pStatus"].Value.ToString();
if (pStatus == "Credit")
{
e.Graphics.DrawString("جمع", font, brush, 40, 170);
}
else
{
e.Graphics.DrawString("بنام", font, brush, 40, 170);
}
}
if (row.Cells["Total Liters"].Value != null)
e.Graphics.DrawString(row.Cells["Total Liters"].Value.ToString(), font, brush, 70, 200);
if (row.Cells["Milk Amount"].Value != null)
e.Graphics.DrawString(row.Cells["Milk Amount"].Value.ToString(), font, brush, 70, 230);
if (row.Cells["Parchi Amount"].Value != null)
e.Graphics.DrawString(row.Cells["Parchi Amount"].Value.ToString(), font, brush, 70, 260);
if (row.Cells["Closing Balance"].Value != null)
e.Graphics.DrawString(row.Cells["Closing Balance"].Value.ToString(), font, brush, 70, 290);
if (row.Cells["Status"].Value != null)
{
string cStatus = row.Cells["Status"].Value.ToString();
if (cStatus == "Credit")
{
e.Graphics.DrawString("جمع", font, brush, 40, 290);
}
else
{
e.Graphics.DrawString("بنام", font, brush, 40, 290);
}
}
e.Graphics.DrawString("--------------------------------------------", linefont, brush, 20, 310);
e.Graphics.DrawString("کسی بھی غلط حساب کی صورت میں جلد از جلد", infofont, brush, 19, 340);
e.Graphics.DrawString("ہم سے رابطہ کریں۔ شکریہ", infofont, brush, 130, 365);
e.Graphics.DrawString("03346565189 :فون نمبر" + " ", infofont, brush, 128, 395);
e.Graphics.DrawString("آپ کے تعاون کا شکریہ", infofont, brush, 80, 425);
currentRow++;
e.HasMorePages = true;
}
else
{
currentRow = 0;
e.HasMorePages=false;
}
}
```
Despite my attempts to print each row on a separate page by setting e.HasMorePages to true after printing each row, the issue persists. |

> I am using following code to get the IP of the client ... and this is outputting IPv4 for some clients, and IPv6 for some
The code is doing the same thing for all clients: outputting the IP address they connected from. If someone connects using IPv6, that's the only address you can get.
Imagine you have a system that assumes everyone will have a postal address in Norway. Then someone signs up with an address in the UK; there's no point trying to find a Norwegian address for them, they don't have one. Either you change the system to handle UK addresses, or you block them from signing up.
You have the same two options here:
* Expand your system so that it can handle IPv6 addresses as well as IPv4 addresses. This is obviously preferred, since it allows everyone to access it, as IPv6 becomes more widespread.
* Block people from accessing your site with IPv6. Ideally, you'd do this at the DNS level, by not having an "AAAA" record, which advertises the IPv6 address for people to connect to; that way, users who have the ability to connect with IPv4 will do so. That would need to happen wherever the proxy is configured, because by the time the request gets to your application server it's too late. |
I’ll just mimic the string in a *pre* tag and do the string parsing...
<!DOCTYPE html><head></head>
<body onload="Process();">
<script>
function Process(){
let S=Cont.innerHTML;
S=S.replace(/\n+/g,'').replace(/ +/g,'').replace(/{/g,' {\n ').replace(/;/g,';\n').replace(/:/g,': ').replace(/,/g,', ');
Cont.innerHTML=S;
}
</script>
<pre id="Cont">
p {
color: hsl(0deg, 100%, 50%;
}
</pre>

It seems that Luxon can be also used with CDN. [Ref](https://cdnjs.com/libraries/luxon) When `https://cdnjs.cloudflare.com/ajax/libs/luxon/3.4.4/luxon.min.js` is used, how about the following sample script?
### Pattern 1:
In this pattern, the script of Luxon is used by copying to the script editor.
1. Please access `https://cdnjs.cloudflare.com/ajax/libs/luxon/3.4.4/luxon.min.js` with your browser.
2. Copy and paste the script from the URL to the script editor of Google Apps Script.
3. When the following sample script is used, a result like `2024-03-31T09:45:27.040+09:00` is obtained.
```javascript
function myFunction() {
const res = luxon.DateTime.now().toISO();
console.log(res); // 2024-03-31T09:45:27.040+09:00
}
```
### Pattern 2:
In this pattern, the script of Luxon is loaded when the script is run.
1. When the following sample script is used, a result like `2024-03-31T09:45:27.040+09:00` is obtained.
```javascript
function myFunction() {
// Load library.
const url = "https://cdnjs.cloudflare.com/ajax/libs/luxon/3.4.4/luxon.min.js";
eval(UrlFetchApp.fetch(url).getContentText());
// Use library.
const res = luxon.DateTime.now().toISO();
console.log(res); // 2024-03-31T09:45:27.040+09:00
}
```
### Note:
- I cannot test all methods of luxon. So, I'm not sure whether all methods can be worked.

Why don't you just validate first and then try the update?
public function update(UpdateUserRequest $request, string $id)
{
// you can just use:
// $request->validated();
// and it throws error or anything you change in failedValidation() method
// or
$validator = Validator::make($request->all(), $request->rules());
if ($validator->fails()) {
return response()->json(['errors' => $validator->errors()], 422);
}
// -
$user = User::findOrFail($id);
$user->update($request->validated());

You could try implementing a custom drag preview by adopting the [`UIDragInteractionDelegate`](https://developer.apple.com/documentation/uikit/uidraginteractiondelegate) in a [`UIViewRepresentable`](https://developer.apple.com/documentation/swiftui/uiviewrepresentable) that wraps your SwiftUI view: by using [`UIDragPreview`](https://developer.apple.com/documentation/uikit/uidragpreview) and setting the preview provider of the [`UIDragItem`](https://developer.apple.com/documentation/uikit/uidragitem), you can specify a custom view for the preview that will be the same size as the original view and without any transparency.
```bash
+---------------------------------+
| +----+ +-------------------+ |
| |Icon| |Title | |
| +----+ +-------------------+ |
| | UIViewRepresentable wrapper |
| +-------------------------------+
| | UIDragInteractionDelegate |
+---------------------------------+
|
| Custom drag behavior
| (UIDragInteractionDelegate)
v
+----------------------------------+
| UIDragPreview (Custom preview) |
| Same size, no transparency |
+----------------------------------+
```
This is inspired from [`Client/Frontend/TabChrome/TopBar/LocationView/LocationViewTouchHandler.swift`](https://github.com/productinfo/neeva-ios/blob/fe8624ef1b7817806da79b4978b5d53a070b1766/Client/Frontend/TabChrome/TopBar/LocationView/LocationViewTouchHandler.swift#L11)
```swift
import SwiftUI
import UIKit
// Wrap your SwiftUI view in a UIViewRepresentable
struct DraggableView: UIViewRepresentable {
var text: String
func makeUIView(context: Context) -> UIView {
let view = UIHostingController(rootView: DraggableTextView(text: text)).view!
view.backgroundColor = .clear
let dragInteraction = UIDragInteraction(delegate: context.coordinator)
view.addInteraction(dragInteraction)
return view
}
func updateUIView(_ uiView: UIView, context: Context) {}
func makeCoordinator() -> Coordinator {
Coordinator()
}
class Coordinator: NSObject, UIDragInteractionDelegate {
func dragInteraction(_ interaction: UIDragInteraction, itemsForBeginning session: UIDragSession) -> [UIDragItem] {
let provider = NSItemProvider(object: "Dragged content" as NSString)
let item = UIDragItem(itemProvider: provider)
item.previewProvider = { return UIDragPreview(view: interaction.view!) }
return [item]
}
}
}
// Your original SwiftUI view
struct DraggableTextView: View {
var text: String
var body: some View {
HStack {
Image(systemName: "hand.point.up.left.fill") // Example icon
Text(text)
Spacer()
}
.padding(16)
.background(Color.gray) // For demo purposes
}
}
struct ContentView: View {
var body: some View {
DraggableView(text: "Draggable Text")
}
}
```
The key part in the code which should allow for a "Same size, no transparency" drag preview is the `previewProvider` closure of `UIDragItem`.
```swift
item.previewProvider = { return UIDragPreview(view: interaction.view!) }
```
The `UIDragPreview` initializer is passed the `interaction.view`, which is the UIView that was created by the `UIHostingController` with the SwiftUI view inside of it. Since you are using the original view itself for the preview, it should have the same size as the original. |
Since a comma can not be in a url, you can narrow the characters in the url to not be a comma with `[^,]`:
\b(?<=,)http[^,]*(?=,)\b
Also you do not need the ? for optional character as * already means zero or more characters. |
i am trying designing a neural network to classify signals by a pytorch model. after training the model i save the model and load it for inference phase.
i am trying designing a neural network to classify signals by a pytorch model. after training the model i save the model by the fllowing code:
```
torch.save(model.state_dict(), ".pth")
```
afterward i want to load the model for inference phase. i use the following code :
```
model_test = spectrogram_model(X_Test)
model_test.load_state_dict(torch.load(".pth"))
```
but i got an error as follows:
```
AttributeError: 'Tensor' object has no attribute 'load_state_dict'
```
do you have any solution? |

You can use `envsubst` to substitute environment variables :
```
psql -h XXX -p 5432 -U XXX -d XXX -f <(envsubst < ./script.sql)
``` |
It isn't reliable to use `implode()` then unconditionally append a trailing delimiter for cases where an array might be empty.
If you are seeking a functional-style approach, then `array_reduce()` can most directly iterate your values as a delimited string.
Code: ([Demo][1])
$array = ['name1', 'name2', 'name3'];
$separator = ', ';
echo array_reduce(
$array,
fn($text, $value) => "$text$value$separator"
);
Output:
name1, name2, name3,
There's nothing wrong with performing the same concatenation with a `foreach()` loop, it just requires a globally scoped variable to be declared versus `array_reduce()`'s function-scoped `$text` variable.

You can use getQueryInterface function and createaDabase function to create database before model initialization .:
import { Sequelize } from "sequelize";
let sequelizeOptions: any = {
dialect: "mysql",
host: process.env.DB_HOST || "localhost",
port: process.env.DB_PORT || 12345,
username: process.env.DB_USER || "root",
password: process.env.DB_PASSWORD || "",
}
export const dataBase = async () => {
// create db if it doesn't already exist
const { host, port, user, password, database } = { host: process.env.DB_HOST, port: process.env.DB_PORT, user: process.env.DB_USER, password: process.env.DB_PASSWORD, database: process.env.DB_NAME || "zconnectmarket" };
// const connection = await mysql.createConnection(({ host, port, user, password } as any));
// await connection.query(`CREATE DATABASE IF NOT EXISTS \`${database}\`;`);
// connect to db
const sequelizeCont = await new Sequelize((sequelizeOptions as any)).getQueryInterface().createDatabase(database);
// sync all models with database
return sequelizeCont;
}
export default new Sequelize(({ ...sequelizeOptions, database: process.env.DB_NAME || "DBNAME" } as any)) |
Instead of extending DefaultBatchConfiguration, you can define custom beans for specific components you want to customize. For example, you can define a custom TaskExecutor bean without extending DefaultBatchConfiguration. This allows you to retain other autoconfigured beans provided by Spring Boot.
@Configuration
public class MyJobConfiguration {
@Bean
public TaskExecutor myTaskExecutor() {
ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
taskExecutor.setMaxPoolSize(MAX_BATCH_TASK_EXECUTOR_POOL_SIZE);
taskExecutor.afterPropertiesSet();
return taskExecutor;
}
} |
