I need to conditionally import a file during a particular type of build. Using grunt-contrib-jshint#0.7.0 which is on top of less#1.4.2
What I tried thus far...
Trying to use protected mixins to determine the type of build I require and namely, to skip imports of certain less files that break in dev mode.
#isProduction: 1;
...
.getImports() when (#isProduction = 1){
}
.getImports() {
#import "productionStyles";
}
...
.getImports();
however, this seems to fail and it tries to import and parse productionStyles.less all the time. I guess protected mixins does not cover #import, so how would you solve that?
I also tried
#productionStyles: "productionStyles"; // or 0
...
#productionStyles: 0;
.getImports() when not (#productionStyles = 0){
#import "#{productionStyles}";
}
...
to same avail, it will try to import it anyway >> FileError: '0.less' wasn't found in ....
I am starting to think it will need a bigger refactor where devStyles and productionStyles are both a thing and I just switch between them - it's just that productionStyles was an addition that can only compile after a full build due to deps and I would much rather solve this by compiling conditionally.
I can also move away from using grunt-contrib-jshint and write my own less parser but would like to explore the built-in options first.
As the productionStyle.less references several files that are not in the file system, is it possible to ignore the #imports that fail and continue building? I would prefer not to disable error checking/break on all errors due to possible parser errors elsewhere...
I've solved your problem using switch parameter:
index.html
<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet/less" type="text/css" href="style.less" />
<script src="less.js" type="text/javascript"></script>
</head>
<body>
[foo]
</body>
</html>
style.less
.mixin(production) {
#import "test.less";
background: #color;
}
.mixin(dev) {
background: green;
}
html {
.mixin(production);
}
test.less
#color: red;
less.js is less v1.4.1 downloaded straight from project page.
Code about should result in red background.
Switching to html { .mixin(dev); } disables #import and background turns green.
It's possible that your solution would work, too, but you have errors in HTML or something like that - I haven't checked that.

I have a component that loads a javascript module that builds on Bootstrap.js and Jquery to automatically build a table of contents for a page based on H1,H2,... headers. The component code is as follows:
import { bindable, bindingMode, customElement, noView } from 'aurelia-framework';
#noView()
#customElement('scriptinjector')
export class ScriptInjector {
#bindable public url;
#bindable public isLocal;
#bindable public isAsync;
#bindable({ defaultBindingMode: bindingMode.oneWay }) protected scripttag;
private tagId = 'bootTOCscript';
public attached() {
if (this.url) {
this.scripttag = document.createElement('script');
if (this.isAsync) {
this.scripttag.async = true;
}
if (this.isLocal) {
System.import(this.url);
return;
} else {
this.scripttag.setAttribute('src', this.url);
}
document.body.appendChild(this.scripttag);
}
}
public detached() {
if (this.scripttag) {
this.scripttag.remove();
}
}
}
Essentially for those not familiar with Aurelia, this simply uses SystemJs to load the bootstrap-toc.js module from my app-bundle wherever I put this on my view:
<scriptinjector url="lib/bootstrap-toc.js" is-local.bind='true'></scriptinjector>
My problem is that although this works perfectly when I first load the view, subsequent visits don't generate a TOC (table of contents). I have checked that Aurelia is in fact calling System.Import each time the view is loaded, but it seems that once a module has been imported once, it is never imported again (the code from the bundle never runs a second time).
Does anyone know how I can unload/reload/reset/rerun the module when I re-enter the view?
Ok, so after days of fighting with this I have figured out an acceptable solution that keeps all the functionality of the TOC library and requires as few changes to the skeleton project and the target library as I could manage. Forget the script injector above.

This is assuming you have installed bootstrap using jspm (which brings in jquery as a dependency). This also assumes you have put the javascript library (the one you want to incorporate, bootstrap-toc in my case) in your src/lib folder and that you have configured your bundling to include js files from your source folder.
Next, if your library has a self executing anonymous function defined, you need to take that code and move it inside the 'attached' method of the viewmodel where you want the library to be applied. So in this case, I have a 'help' view with a bunch of sections/subsections that I wanted a TOC generated for, so the code looks like:
import { singleton } from 'aurelia-framework';
#singleton()
export class Help {
public attached() {
$('nav[data-toggle="toc"]').each((i, el) => {
const $nav = $(el);
window.Toc.init($nav);
});
}
}
The code inside the 'attached' method above was cut and pasted from the bootstrap-toc.js file and I removed the self-executing anonymous method.
I tried using system.import for the jquery/bootstrap libraries but that made part of the TOC functionality stop working and I have lost my patience to figure out why so those libraries are staying as script references for now.
Also, when you build the project you will get errors :
help.ts(7,7): error TS2304: Cannot find name '$'.
help.ts(9,16): error TS2339: Property 'Toc' does not exist on type 'Window'.
These do not cause problems at runtime since both $ and Toc will be defined before the view is ever instantiated. You can solve these build errors with this solution here.
I'm currently trying to develop using IntelliJ and my issue is that for each typescript file I have to add an explicit reference to everything used in that file.
Also, the transpiled output of TS->JS also needs to be referenced individually.
Is there a way to lessen the friction here?
It would be nice to not have to deal with references between files.
And some sort of bundling for the TS files would also be nice.
Not sure you can avoid references, but I am using requirejs and it make code looks like java/c#, intellisense working fine

import module1 = require("module1");
import module2 = require("module2");
var class1 = new module1.Class1();

console.log("Class1 created")

module2.ts

}
Of course you must add require.js in to the project and add "--module amd" in Idea Settings->Languages & Frameworks -> TypeScript -> Command line options
This way is more readable and you can see in where you use external code and you can cleanup unused imports and another benefit you can write modular code.
I've added this code at the top of themes/bootstrap/views/layouts/main.php
Yii::app()->clientScript->registerScriptFile(Yii::app()->baseUrl . '/js/custom.js');
in my html it does show
<head>
<script type="text/javascript" src="/dev2/js/custom.js"></script>
</head>
and in the custom.js file i have this
jQuery(function($) {
alert('test');
}
when the page loads, i don't get any alert showing. the files do exist in the right directory and i get no firebug warnings. All JS files that i've manually included using registerScriptFile for some reason doesn't work. None of my plugins i've included work. Any ideas?
You can try this:
$(document).ready(function(){
alert('hello');
// Enter code here
});
in your custom.js .
Yii::app()->clientScript->registerScriptFile(Yii::app()->baseUrl.'/js/custom', CClientScript::POS_HEAD);
and wrong in script:
jQuery(function($) {
alert('test');
});
have to work
I'm trying to add a simple progress bar to my application in rails using jquery-ui. I'm following this example: http://jqueryui.com/progressbar/
I create the div
<div id="progressbar"></div>
and in my JS I have
$(document).ready( function() {
$("#progressbar").progressbar({
value: 37
});
});
But nothing happens to the div in the html - it remains empty and unstyled(ie no additional CSS is applied to it).
I have checked that I have jquery-ui included in my application - in particular, I have made certain the jquery-ui css file is included.
However, I am willing to bet the problem has something to do with jquery-ui not working properly in my app, because I was having another issue with it and the tooltip function, which I asked about over here: positioning jQuery tooltip
This is driving me nuts, does anyone have any ideas?
I had the same problem right now.
It seems like the referenced libaries in the example do not work.
The error i get from the "Firefox - Developer Tools - Browser Console" is:
ReferenceError: $ is not defined
(I tested on Firefox 32.0.3 and IE 11)
If you just copy the example html/jquery source from "http://jqueryui.com/progressbar/" to a local file (lets call it: "testJqueryProgressBar.html") and double click it, you will see no progress bar!
Source of "testJqueryProgressBar.html":
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery UI Progressbar - Default functionality</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.1/jquery-ui.js"></script>
<link rel="stylesheet" href="//jqueryui.com/resources/demos/style.css">
<script>
$(function()
{
$( "#progressbar" ).progressbar({ value: 37 });
});
</script>
</head>
<body>
<div id="progressbar"></div>
</body>
</html>
Therefore i checked the links in the header of the example and all reference something.
So the links are valid!
I even tried to reference the jquery libs from another provider, f.e. : https://developers.google.com/speed/libraries/devguide?hl=de#jquery-ui.
Same problem!
Then i went to http://jqueryui.com/download/
Selected Version : 1.11.1 (Stable, for jQuery1.6+)
Selected a different UI theme at the bottom
Downloaded the zip and referenced these unziped jquery sources in my local example testJqueryProgressBar.html and it worked.
I want to use a simple Sencha Touch keypad plugin.
The plugin code can be found over here.
The keypad can be created in an html file under tags as follows:
<script>
Ext.setup({
onReady: function () {
var basic = new Ext.ux.Keypad();
basic.render('keypad');
}
});
</script>
<div id="keypad"/>
Alternatively, it can be used in a Sencha container as follows too:
...
items:[
{
xtype: 'keypad'
}
]
However, I am not able to get it to work the latter way. I'm new to Sencha and I think I'm not placing the files at the right places or not including them properly. I have already included the following in my index.html:
<script type="text/javascript" charset="utf-8" src="js/sencha-touch-1.1.1/sencha-touch.js"></script>
<link rel="stylesheet" type="text/css" href="js/sencha-touch-1.1.1/resources/css/sencha-touch.css">
<script src="js/Keypad.js" type="text/javascript" charset="utf-8"></script>
Can someone let me know what modifications are necessary in which files so that I can use the keypad plugin directly in a container?
in your app.js file you need to set path for the plugin folder in the loader...
put the ux (plugin)folder where your app.js is located...
in app.js set the following
Ext.Loader.setPath('Ext.ux', 'ux');
On the view where you are using the numpad you need to specify a
requires: ['Ext.ux.NumPad' ...] //All plugin related files
Also ensure that the CSS files are in the proper location...
Hope it helps...
