When developing stuff I need to output the state of some instance in order to inspect it.
While using CakePHP I always had a debug() function which does some kind of var_dump inside a <pre> html element, so the content is readable.
Is something similar in Symfony 2.x too?
exit(\Doctrine\Common\Util\Debug::dump($someVar));
use
\Doctrine\Common\Util\Debug::dump($user);
As of today, one of the best ways to debug in Symfony that I know of is the Ladybug Bundle. Its output is similar to xdebug's, but it has some nice features, like a collapsible tree structure for arays or automatically linking to documentation pages (supporting standard PHP, Doctrine and Symfony).
You can find some great examples of its use on the README.
Now there is a new function in Symfony - dump(), have a look at http://symfony.com/blog/new-in-symfony-2-6-vardumper-component

I am working on going through the Style guide for Angular 2 and I happened upon this line
Do end the filename of a RoutingModule with -routing.module.ts.
I haven't had luck finding anything on routing module examples so I went to Papa's blog. There I found this line...
The forRoot() function should only be used for creating the root modules' routes. When we get to child modules and routes, we'll use other techniques that we'll see in later posts.
So how do I create a RouteModule that isn't using forRoot like suggested.
I think I found an example here...

I'm trying to modify the skin of the register.html.twig template found in FOSUserBundle/Resources/views/Registration/register.html.twig.
I've basically followed the instructions in the documentation down to a T.
Like it told to do so, I created /app/Resources/views/FOSUserBundle/views/Registration/register.html.twig.
Cleared the cache (and browser cache just to be sure)
NO effect! I've put a blank file in register.html.twig, but no matter what I put there, when I go to /register/, I still see the default template.
Yep, these things happen all the time.
It should be:
/app/Resources/FOSUserBundle/views/Registration/register.html.twig

I'm using Symfony2 with Twig templating engine.
Is there any way to output a list of all Twig templates files loaded in the current request, including the ones loaded through extends, include, etc.?
That would make my life much easier when overriding third-party bundles' blocks, but I can't find a way to do it.
I've been looking for such a tool for a long time but never found it... The debug options of twig are very limited, and there is no tool in the sf2 dev bar dedicated to it...
I always add twig or html comments on top of each of my templates to get an idea of where I am and why during development or on the final page.
You can try this code, it puts filenames in HTML like this:
<!-- START templatename.html.twig -->
...
<!-- END templatename.html.twig -->
I know, that it is not a good solution, but it is better than nothing.
not a problem when you are working in dev in app_dev.php
expand bottom SF toolbar, click on 200 status or on #your_rote_name
you will redirect to smt like localhost/_profiler/s0meha5h?panel=*
then click on left menu on TWIG then url will be like localhost/_profiler/s0meha5h?panel=twig
and you will see all templates like FolderYourBundle:Folder:twig_file_name.html.twig that loads one by one!
I am exploring ASP.NET MVC and I wanted to add jQuery to make the site interactive. I used StringTemplate, ported to .Net, as my template engine to generate html and to send JSON. However, when I view the page, I could not see it. After debugging, I've realized that the $ is used by the StringTemplate to access property, etc and jQuery uses it too to manipulate the DOM. Gee, I've looked on other template engines and most of them uses the dollar sign :(.
Any alternative template engine for ASP.Net MVC? I wanted to retain jQuery because MSFT announced that it will used in the Visual Studio (2008?)
Thanks in Advance :)
Update
Please go to the answer in ASP.NET MVC View Engine Comparison question for a comprehensive list of Template engine for ASP.NET MVC, and their pros and cons
Update 2
At the end I'll just put the JavaScript code, including JQuery, in a separate script file, hence I wouldn't worry about the $ mingling in the template file.
Update 3
Changed the Title to reflect what I need to resolve. After all "The Best X in Y" is very subjective question.
You can of course move your js logic into a .js file. But if you want it inline with your StringTemplate views, you can escape it using the \$ construct.
In addition, you can simply use the jQuery("selector"), instead of $("selector") construct if you want to avoid the escaping syntax.
Here's a good article on using StringTemplate as a View Engine in MVC.
There's also an accompanying OpenSource engine, along with some samples.
Also, as mentioned above, you can modify your Type Lexer. (make it an alternate character to the $).
I would highly recommend Spark. I've been using it for awhile now with jQuery and haven't ran into a single issue so far.
JQuery can be disambiguated by using the jQuery keyword like this:
jQuery(
instead of this:
$(
I would consider this a best practice. It eliminates any possibility of clashing with another library, and makes the code more readable.
Perhaps jQuery.noConflict will work for you
Have a look at the mvccontrib project. They have 4 different view engines at the moment which are brail, nhaml, nvelocity and xslt.
http://www.codeplex.com/MVCContrib
In case you want to stick with StringTemplate (ST) see this article from the ST wiki. You may also change the behaviour totally by editing Antlr.StringTemplate.Language\DefaultTemplateLexer.cs and replacing the "$" with what you want.
I really like the syntax in Django, so I recommend NDjango :)
Have you tried $$ or /$ to escape the dollar signs in string template? I'm not sure about ST specifically but thats how most template engines work.
As for other templating engines, I really loved nVelocity when I used it on a project.
JsonFx.NET has a powerful client-side templating engine with familiar ASP.NET style syntax. The entire framework is specifically designed to work well with jQuery and ASP.NET MVC. You can get examples of how to build real world UI from: http://code.google.com/p/jsonfx-examples/
I've been using ANTLR StringTemplate for ASP.NET MVC project. However what I did was to extend the StringTemplate grammar (template.g) to recognize '%' (aspx.template.g) as delimiters. You can find these files if you download the StringTemplate.net version. I generated the corresponding files: AspxTemplateLexer.cs, AspxTemplateParser.cs, AspxTemplateParserTokenTypes.cs and AspxTemplateParserTokenTypes.txt.
In addition I altered StringTemplateLoader.cs to recognize the extensions .aspx and .ascx which Visual Studio recognizes. This way I am not stuck with the .st extension and clients don't know the difference.
Anyway after rebuilding StringTemplate I have the behavior that I want. What I like about StringTemplate is that it does NOT permit ANY code to be embedded in the template. It looks like Spark like the default ASP/MVC template is code permissive which makes the templates less portable.
I would prefer is "<%" and "%>" as delimiters but unfortunately the ANTLR grammar seems somewhat difficult and fragile to alter unless someone else has done it. On the other had StringTemplate has a great support community and a great approach to separation -- which is the point of MVC.
You could try jsRepeater.
You may need this .NET Template Engine. If you wish to use '$' character, simply use '$$'. See the code below:
{%carName = "Audi R8"/}
{%string str = "This is an $carName$"/}
$str$
$$str$$
the output will be
This is an Audi R8
$str$
If I understand StringTemplate version 4 correctly you can define your own escape char in Template (or TemplateGroup) constructor.
Found Mustache to be the most fool-proof, easiest-to-use, lightest full-featured templating engine for .Net projects (Web and backend)
Works well with .Net 3.5 (meaning it does not need dynamic type and .Net 4.0 to work for mixed type models, like Razor).
The part that I like the most is ability to nest arbitrary IDicts within and have the engine do the right thing. This makes the mandatory-for-all engines reboxing step super-simple:
var child = new {
nested = "nested value"
};
var parent = new {
SomeValue = "asdfadsf"
, down = child
, number = 123
};
var template = #"This is {{#down}}{{nested}}{{/down}}. Yeah to the power of {{number}}";
string output = Nustache.Core.Render.StringToString(template,parent);
// output:
// "This is nested value. Yeah to the power of 123"
What's most beautiful about Mustache is that same exact template works exactly same in pure JavaScript or any other of 20 or so supported languages.
I have a legacy application that I needed to implement a configuration page for to change text colors, fonts, etc.
This applications output is also replicated with a PHP web application, where the fonts, colors, etc. are configured in a style sheet.
I've not worked with CSS previously.
Is there a programatic way to modify the CSS and save it without resorting to string parsing or regex?
The application is VB6, but I could write a .net tool that would do the css manipulation if that was the only way.
You don't need to edit the existing one. You could have a new one that overrides the other -- you include this one after the other in your HTML. That's what the "Cascading" means.
It looks like someone's already done a VB.NET CSS parser which is F/OSS, so you could probably adapt it to your needs if you're comfortable with the license.
http://vbcssparser.sourceforge.net/
One hack is to create a PHP script that all output is passed through, which then replaces certain parts of CSS with configurable alternatives. If you use .htaccess you can make all output go through the script.
the best way i can think of solving this problem is creating an application that will get some values ( through the URL query ) and generate the appropriate css output based on a css templates
Check this out, it uses ASP.NET and C#.
In my work with the IE control (shadocvw.dll), it has an interesting ability to let you easily manage the CSS of a page and show the effects of modified CSS on a page in realtime. I've never dealt with the details of such implementations myself, but I recommend that as a possible solution worth looking at. Seeing as pretty much everyone is on IE 6 or later nowadays, you can skip the explanations about handling those who only have IE 5,4,3 or 2 installed.
Maybe the problem's solution, which is most simple for the programmer and a user is to edit css via html form, maybe. I suppose, to create css-file, which would be "default" or "standart" for this application, and just to read it, for example, by perl script, edit in html and to write it down. Here is just the simple example.
In css-file we have string like:
border-color: #008a77;
we have to to read this string, split it up, and send to a file, which will write it down. Get something like this in Perl:
tr/ / /s;
($vari, $value) = split(/:/, _$);
# # While you read file, you can just at the time to put this into html form
echo($vari.":<input type = text name = ".$vari." value = ".$value.">");
And here it is, you've got just simple html-form-data, you just shoul overwrite your css-file with new data like this:
...
print $vari[i].": ".$value.";\n";
...
and voila - you've got programmatical way of changing css. Ofcourse, you have to make it more universal, and more close to your particular problem.
Depending on how technically oriented your CSS editors are going to be, you could do it very simply by loading the whole thing up into a TextEdit field to let them edit it - then write it back to the file.
Parsing and creating an interface for all the possibilities of CSS would be an astronomical pain. :-)
