37,022,139 | Android Studio: product flavor combination with more than two flavor dimensions (flavor groups) | <p>I am developing an Android application using Android Studio (v 2.1, gradle plugin v 2.1.0). My application has various versions which share a lot of common code so I decided to use flavor dimensions and product flavors to customize code and resources when and where it is requested. This worked fined as long as I only had two flavor dimensions. As an example, my <code>app.gradle</code> was</p>
<pre><code>…
flavorDimensions "fruit", "color"
productFlavors {
apple {
dimension "fruit"
}
pear {
dimension "fruit"
}
red {
dimension "color"
}
yellow {
dimension "color"
}
}
…
</code></pre>
<p>and my <code>src</code> folder was</p>
<pre><code>src/
appleRed/
appleYellow/
pearRed/
pearYellow/
</code></pre>
<p>each one with a custom version of my code. Again, as an example</p>
<pre><code>src/
appleRed/java/com/example/ExampleFragment.java
appleYellow/java/com/example/ExampleFragment.java
pearRed/java/com/example/ExampleFragment.java
pearYellow/java/com/example/ExampleFragment.java
</code></pre>
<p>of course, there is no instance of <code>ExampleFragment</code> in <code>src/main</code>.</p>
<p>At some point during development, I had to include a <em>free</em> and a <em>paid</em> version of the app. I thought that it could be easily achieved by adding a new flavor dimension named <code>version</code> and two product flavors named <code>free</code> and <code>paid</code>:</p>
<pre><code> …
flavorDimensions "fruit", "color”, “version”
productFlavors {
apple {
dimension "fruit"
}
pear {
dimension "fruit"
}
red {
dimension "color"
}
yellow {
dimension "color"
}
free {
dimension "version"
}
paid {
dimension “version”
}
}
…
</code></pre>
<p>but all of a sudden the custom code generated by the combination of <code>fruit</code> and <code>color</code> was not detected by Android Studio anymore. So no <code>appleRed</code>, <code>appleYellow</code>, <code>pearRed</code> nor <code>pearYellow</code> can be used to have custom code and the only way I was able to regain my configuration was to use all the combinations of all the three flavour dimensions:</p>
<pre><code> src/
appleRedFree/java/com/example/ExampleFragment.java
appleRedPaid/java/com/example/ExampleFragment.java
appleYellowFree/java/com/example/ExampleFragment.java
appleYellowPaid/java/com/example/ExampleFragment.java
pearRedFree/java/com/example/ExampleFragment.java
pearRedPaid/java/com/example/ExampleFragment.java
pearYellowFree/java/com/example/ExampleFragment.java
pearYellowPaid/java/com/example/ExampleFragment.java
</code></pre>
<p>This is not good because <code>ExampleFragment</code> is duplicated across the same <code>fruitColor*</code> combination (<code>appleRedFree</code>, <code>appleRedPaid</code> have the same <code>ExampleFragment</code>). Same problem happens for resources (the ones in <code>res</code> folder).</p>
<p>My questions are: </p>
<p>1) Is this the expected behaviour from gradle in Android Studio (<em>i.e.</em>, not being able to combine a subset of product flavors, following their priority based on their dimension, when having more than two flavour dimensions)?</p>
<p>2) Given the fact that this is the expected behaviour, is there another way I can achieve my customisation without duplicated code or without having a single file with an <em>if-statement</em> inside (<em>e.g.</em>, <code>if (BuildConfig.FLAVOR_version == "free") ...</code>) ? </p>
<p>Please note that I’m talking about having custom code which could be complex, so I’m not asking for basic customisation like a build config variable, variant filtering, or something like that.</p>

37,022,460 | Best practies CodeIgniter Templating | <p>I'm using CodeIgniter for few years for my PHP project.
Now I'm thinking how improve my view folder structure, using best practies.</p>
<p>I'll explain better. Basically I divide my webpage into 3 view: </p>
<ul>
<li>Header (/view/inc/header.php)</li>
<li>SomeContent (/view/content_of_myView)</li>
<li>Footer (/view/inc/footer.php)</li>
</ul>
<p>My question is very simple: is this the best way? Or there are differents method to generate an header, maybe loading dinamycally all css/js assets with versioning?
I don't want to use any template engine, sincerely I don't like very much.</p>

37,022,602 | How to get sum of array with "for" loop | <p>I'm a total newbie in <code>JavaScript</code>. I'm trying to learn it using programming experience in <code>Python</code>... </p>
<p>Let's say there is an array of integers <code>[2,3,4,5]</code>. I want to get sum of all items in it with <code>for</code> loop. In <code>Python</code> this gonna looks like</p>
<pre><code>list_sum = 0
for i in [2,3,4,5]:
list_sum += i
</code></pre>
<p>Result is <code>14</code></p>
<p>But if I try same in <code>JavaScript</code>:</p>
<pre><code>var listSum = 0;
for (i in [2,3,4,5])
{
listSum += i;
}
</code></pre>
<p>This will return <code>00123</code>. Seems that item indexes concatenated in a string with initial <code>listSum</code> value. How to make code works as intended and to get sum of all array items as integer?</p>

37,052,180 | Value of a for loop in Ruby | I understand that, in Ruby, a for loop is an expression and therefore has a value which can be assigned to a variable. For example, `x = for i in 0..3 do end` sets `x` to `0..3` - the range over which the loop iterates.
Is the value of a for loop always the range as above, or can it differ depending on the body of the loop? | <ruby><for-loop><expression> | 2016-05-05 13:39:38 | LQ_EDIT |

37,067,619 | Do I need to replace NSURLConnection in order to achieve mandatory support for IPv6-only services? | <p>As Apple is requesting app submitted for review must support IPv6-only network starting from 1st June 2016, I am checking if I need to replace certain API / libraries in my app. However I don't know much enough about networking and some related aspects, as a result I am unable to have a definite answer on this and would like to seek for help.</p>
<p>Regarding the document <a href="https://developer.apple.com/library/mac/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/UnderstandingandPreparingfortheIPv6Transition/UnderstandingandPreparingfortheIPv6Transition.html#//apple_ref/doc/uid/TP40010220-CH213-SW13" rel="noreferrer">Supporting IPv6 DNS64/NAT64 Networks</a> provided by Apple, it states that apps should be fine and no need to perform update if:</p>
<blockquote>
<p>you’re writing a client-side app using high-level networking APIs such
as <strong>NSURLSession</strong> and the <strong>CFNetwork frameworks</strong> and you <strong>connect by name</strong></p>
</blockquote>
<p>By this I take it as 2 criteria:</p>
<ol>
<li>using NSURLSession or CFNetwork</li>
<li>connect by name</li>
</ol>
<p>So the question here is:</p>
<ol>
<li><p>As far as I know NSURLConnection is based on CFNetwork, does this mean I will be fine too if my app is using NSURLConnection? (I saw NSURLConnection is also mentioned in <a href="https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/art/NetworkingFrameworksAndAPIs_2x.png" rel="noreferrer">this image in the above document</a>, but again I am not quite sure about this as NSURLConnection is kind of old? And seems I cannot find documents mentioning IPv4 and IPv6 support either.)</p></li>
<li><p>By the criteria "calling by name", does this mean no matter I am using NSURLSession or NSURLConnection, if I happen to call or access certain resources / APIs by an IPv4 address, bad things will happen? (I've done some research, and from my understanding clients like iOS device with iOS 9+ will always use synthesized IPv6 address to access IPv4 server, as a result the client will fail to reach the resource if I call by IPv4 address?)</p></li>
</ol>
<p>Thanks for any help!</p>

37,073,271 | Programatically create a complex JSONArray in Android? | I have been struggling trying to make this work properly. From what I have read the following example is a JSONArray. I need to be able to dynamically create such an array problematically within my Android code, so that it can output this array to a web service. I am most confused about adding the top "header" information and the nested "Position" JSONObject as the last property. I know how a basic JSONObject is created, as well as a basic JSONArray, but this combined one is really throwing me off. Any help would be much appreciated.

37,076,113 | MockRestServiceServer simulate backend timeout in integration test | <p>I am writing some kind of integration test on my REST controller using MockRestServiceServer to mock backend behaviour.
What I am trying to achieve now is to simulate very slow response from backend which would finally lead to timeout in my application. It seems that it can be implemented with WireMock but at the moment I would like to stick to MockRestServiceServer.</p>
<p>I am creating server like this:</p>
<pre><code>myMock = MockRestServiceServer.createServer(asyncRestTemplate);
</code></pre>
<p>And then I'm mocking my backend behaviour like:</p>
<pre><code>myMock.expect(requestTo("http://myfakeurl.blabla"))
.andExpect(method(HttpMethod.GET))
.andRespond(withSuccess(myJsonResponse, MediaType.APPLICATION_JSON));
</code></pre>
<p>Is it possible to add some kind of a delay or timeout or other kind of latency to the response (or maybe whole mocked server or even my asyncRestTemplate)? Or should I just switch to WireMock or maybe Restito?</p>

<input [(ngModel)]="proposition1.wordingP" type="text" class="md-input" required class="md-input"/>
</div>

this.proposition1.propStatus = false;
this.propositionService.addProposition(this.proposition1)
.subscribe(response=> {
console.log(response);
console.log(this.proposition1);

37,078,710 | How Do We Inherit Test Classes Across Android Library Modules? | <p>I have an Android Studio project with two library modules: <code>foo-module</code> and <code>bar-module</code>. Each implements a library, with <code>foo-module</code> defining a strategy interface and <code>bar-module</code> depending upon <code>foo-module</code> and implementing such a strategy. <code>foo-module</code> has instrumentation tests (<code>foo-module/src/androidTest/</code>) to test its core code, using a stub strategy implementation, and <code>bar-module</code> should have its own instrumentation tests.</p>
<p>I defined an <code>AbstractTests</code> class in <code>foo-module/src/androidTest/</code> that does most of the actual testing. I also have a <code>StubTests</code> class in <code>foo-module/src/androidTest/</code> that extends <code>AbstractTests</code> and implements the necessary <code>abstract</code> methods to complete the test case (providing an implementation of the strategy, etc.). This all works great.</p>
<p>In <code>bar-module/src/androidTest/</code>, I created a <code>BarStrategyTests</code> class, designed to mirror <code>StubTests</code>, but provide the strategy implemented in <code>bar-module</code>. However, <code>BarStrategyTests</code> cannot see <code>AbstractTests</code>, even though I have <code>compile project(':foo-module')</code> in my <code>build.gradle</code> file, and the main (non-test) classes in <code>bar-module</code> can work fine with the main (non-test) classes in <code>foo-module</code>. IOW, while the <code>project()</code> dependency handles regular code, it does not handle <code>androidTest/</code> code. I get "error: package com.commonsware.foo.test does not exist".</p>
<p>I tried also adding <code>androidTestCompile project(':foo-module')</code>, with the same result.</p>
<p>What is the recipe for sharing instrumentation test code between modules?</p>
<p>Temporarily, I can clone <code>AbstractTests</code>, but that's not a great long-term solution.</p>
<p><a href="https://stackoverflow.com/q/31814812/115145">This SO question</a> covers similar ground for ordinary Java. Has anyone tried the options in <a href="https://stackoverflow.com/a/32780697/115145">the one answer</a> and gotten them to work for Android instrumentation tests? The first option (move the common testing code into yet another module as regular non-test code) seems plausible, but I have no idea if the other two will work well with the <code>com.android.library</code> plugin instead of the <code>java</code> plugin.</p>

37,079,847 | Is it ok to use ReactDOMServer.renderToString in the browser in areas where React isn't directly managing the DOM? | <p>I'm working on an app using <a href="http://leafletjs.com/" rel="noreferrer">Leaflet</a> (via <a href="https://github.com/PaulLeCam/react-leaflet" rel="noreferrer">react-leaflet</a>). Leaflet directly manipulates the DOM. The react-leaflet library doesn't change that, it just gives you React components that you can use to control your Leaflet map in a React-friendly way.</p>
<p>In this app, I want to use custom map markers that are divs containing a few simple elements. The way to do that in Leaflet is to set your marker's <code>icon</code> property to a <a href="http://leafletjs.com/reference.html#divicon" rel="noreferrer">DivIcon</a>, in which you can set your custom HTML. You set that inner HTML by setting the DivIcon's <code>html</code> property to a string containing the HTML. In my case, I want that HTML to be rendered from a React component.</p>
<p>In order to do that, it seems like the correct approach is to use <code>ReactDOMServer.renderToString()</code> to render the Component that I want inside the map marker into a string, which I would then set as the <code>html</code> property of the DivIcon:</p>
<p><strong><em>MyMarker.js:</em></strong></p>
<pre><code>import React, { Component } from 'react'
import { renderToString } from 'react-dom/server'
import { Marker } from 'react-leaflet'
import { divIcon } from 'leaflet'
import MarkerContents from './MarkerContents'
export class MyMarker extends Component {
render() {
const markerContents = renderToString(<MarkerContents data={this.props.data} />)
const myDivIcon = divIcon({
className: 'my-marker',
html: markerContents
})
return (
<Marker
position={this.props.position}
icon={myDivIcon} />
)
}
}
</code></pre>
<p>However, according to the <a href="https://facebook.github.io/react/docs/top-level-api.html#reactdomserver.rendertostring" rel="noreferrer">React docs</a>:</p>
<blockquote>
<p>This [renderToString] should only be used on the server.</p>
</blockquote>
<p>Is this a strict rule, or is it only meant to dissuade people from circumventing ReactDOM's efficient management of the DOM?</p>
<p>I can't think of another (better) way to accomplish what I'm after. Any comments or ideas would be greatly appreciated.</p>

37,080,472 | How to fully pass a List? | <p>I use a list to contain data parsed from an XML file, using strings as its members:</p>
<pre><code>public class ServerList
{
public string ServerName { set; get; }
public string ServerReboot { set; get; }
public string ServerShutdown { set; get; }
public ServerList()
{
ServerName = "";
ServerReboot = "";
ServerShutdown = "";
}
}
</code></pre>
<p>From the main form I launch an editor form and pass the list into it. On this editor form the user is able to add or remove entry entries form the list, as well as make changes to parts of the list. If they click the OK button I want to be able to pull the list form the editor form back into the main form, but if they click Cancel I want these changes to get dropped. This is the way the editor form is pulled up:</p>
<pre><code> private void mnuEdit_Click(object sender, EventArgs e)
{
frmEditor theEditor = new frmEditor();
theEditor.updatedServerList = theServerList;
DialogResult res = theEditor.ShowDialog();
if (res == DialogResult.OK)
{
theServerList = theEditor.updatedServerList.ToList();
SetupFilters(GroupOrBatch.Group);
// other processing to update the main form from the updated list
}
}
</code></pre>
<p>And on the Edit form this is how it is received:</p>
<pre><code>public partial class frmEditor : Form
{
private List<ServerList> myServerList = new List<ServerList>();
public List<ServerList> updatedServerList
{
get { return myServerList; }
set { myServerList = value.ToList(); }
}
....
</code></pre>
<p>What I am finding is that while the list structure appears to be copied to the new variable, the actual data is still linked to the original list. Even if the user clicks Cancel, and the modified list is not copied back to the original, the original has already been changed.</p>
<p>This leaves me with one of two options - either I can find some way to do a full deep clone of the list to a new one (which can be dropped upon an Cancel), or I remove the Cancel button entirely and have all edits be live. </p>

37,080,490 | Experiment With C | <pre><code>#include<stdio.h>
int main() {
int x = 99;
printf("%d %d\n",1 > scanf("%d",&x) ? scanf("%d",&x): scanf("%d",&x),x);
}
</code></pre>
<p>So What is happening to the scanned values.
Lets say First Input is 11. so left most scanf is returning 1. So according to the rule the right most scanf will be executed. But The right most %d of printf is not printing the scanned value. It is showing 99.</p>

37,081,350 | Check how many times was form submited | <p>I am wondering how can I check is someone tried to log in on site and if he fails login few times to redirect him on forgot password page. I am little word less so I don't know what should I look for. I should try it with jquery and ajax.
I think about something with if password is wrong to echo password is wrong but on third time to send user on forgot page. Now my question is how can I check how many times did someone press submit button with error message for wrong password or username. </p>
