I've got Twig and Mustache combined. Since they both use same tags for bookmarks
{{ var }}
I changed Mustache tags, like this
Mustache.parse(template, ['${', '}']);
So I use this bookmark in Mustache
${ var }
And there are no conflicts.
The problem comes out when I need to tell Mustache not to escape HTML. As the Documentation says, I am to use
{{{ do_not_escape_this_var }}}
But this leads to a conflict with Twig! And It seems like there is no way tu customize it.
I know I could override Twig's bookmarks, but this is bad for the frontend team, used to Twig default tag.
Any solutions? Thank you
Like the Twig's documentation says, code can be escaped like this:
{{ '{{{ do_not_escape_this_var }}}' }}
For larger blocks of code, you can use verbatim to prevent Twig from parsing Mustache code as Twig code:
{% verbatim %}
{{{ do_not_escape_this_var }}}
{% endverbatim %}
With verbatim, you could also avoid parsing chunks of Mustache code with the default Mustache tags:
{% verbatim %}
<h1>Hello {{ name }}!</h1>
<p>How are you {{ today }}?</p>
{{! This is just Mustache, not Twig }}
{% endverbatim %}
Of course, then you can't use Twig between {% verbatim %} and {% endverbatim %}. I don't think it's a problem as mixing Mustache (with the default tags) and Twig code would be very confusing.

I want to make modular css load with instruction in twig
{{ addCss("csspath") }}
{# rest of template #}
and then write all css in a twig block in my html header like this :
{% block css %}
{{ writeCss() }}
{% endblock %}
My custom function work well, all css store with addCss will be write by writeCss but I have some problem with twig processing order. Css needs to be in head html tag and because of that twig process writeCss before all my addCss call.
I've made some test to guess twig process order by i have no ideo of how control it.
We are using Twig as our templating engine but I'm stuck with a problem of the rendering order now. See - https://straightupcraft.com/articles/twig-processing-order
We are using amp for our new site and with amp and web components in general it is necessary to import the components (once) to use them. So the idea was to create a Twig Extension to accomplish exactly this. Everytime a component is used it is called via this twig function call. The function is checking the component, adding it to a stack and you can use it from now on. The stack then is transformed into a list of imports for the head of the page.
The problem here is Twigs top to bottom rendering. When I call said function in a partial or a template the rendering of "layout.twig" already took place and all function calls below/after are not affecting the stack.
Is there an option to change the rendering to inside out, so that the rendering is first using the lowest partial and "bubbles" up to templates and finally layout without them rendering before?
Another way to get the values in layout would nice as well.
Desired behavior:
Layout.twig
{{ getAllComponents() }}
{# should output component1 and component2 #}
{% block content %}
Page.twig
{% extends Layout.twig %}
{{ addComponent('component1') }}
{% include partials.twig %}
<component1>...</component1>
partials.twig
{{ addComponent('component2') }}
<component2>...</component2>
Actual behavior:
Layout.twig
{{ getAllComponents() }}
{# is empty #}
There is no option to change this behavior. However you can use a trick to archive this:
Render your content to a variable before you call getAllComponents()
layout.twig
{% set mainContent %}
{% block content %}{% endblock %}
{% endset %}
{{ getAllComponents() }}
{{ mainContent }}
There actually is a magical solution to this problem -- some genius wrote this Deferred Twig Extension which lets you run some code (output a variable, call a function, etc) in a block near the top of your layout, but wait until the rest of the twig templates have parsed before executing them. There's an example on that github page showing how you can achieve this.
As far as I know, no you cannot switch the rendering of a TWIG template.
However, I would recommend possibly looking at the {% embed %} or {{ render }} tags.
Embed allows specific TWIG files to be placed within others with variables, so you could pass each component into their relevant partials.twig file.
Render allows the use of embedding a separate controller action, so you create a ControllerAction that took in a component variable and renders its own TWIG file.

I am using the node version of patternlab with twig as template engine. I am using twig because my codebase is written in twig - so using mustache it not an option.
I simple try to include an pattern:
<button type="button" class="btn {{ buttonClass }}">{{ cta }}</button>
in an other pattern with:
{% include "base-button" with {'buttonClass': 'btn-primary btn-xs'} %}
This does not work. The pattern is included but the variable buttonClass is not set.
Any Ideas?
This seems to be an issue with the twig integration in this repo https://github.com/pattern-lab/patternengine-node-twig.
There are other issues with twig core features described here: https://github.com/pattern-lab/patternlab-node/issues/554
I finally decided to switch to the php/twig edition and the same twig-patterns are working as expected. If anybody have to use the node edition, i recommend to use mustache.
I believe there are plans to pass the Twig rendering in Pattern Lab Node to PHP, however, this isn't ready yet, but using The Twig engine for Patternlab/Node you can pass a variable via an include. It doesn't work exactly the same as normal twig but it does work.
{% set buttonClass = 'btn-primary btn-xs' %}
{% include "components-button" with buttonClass %}
You can also pass multiple variables:
{% include "components-button" with buttonClass anotherVariable %}
I want to translate a whole html page (text and some markup) including <p>,<italic>, <strong> tags in Symfony2. For simple phrases I use {{ 'read.first'|trans }} but this does not accept html tags like <p>. How do I do that ?
You shouldn't translate complete pages with the Translation component of symfony, that is meaned for just short strings.
Twig always escapes tags in strings, you can read in the translation docs how to disable this for your translations:
Using the translation tags or filters have the same effect, but with one subtle difference:
automatic output escaping is only applied to variables translated using a filter. In other
words, if you need to be sure that your translated variable is not output escaped, you must
apply the raw filter after the translation filter:
{# text translated between tags is never escaped #}
{% trans %}
<h3>foo</h3>
{% endtrans %}
{% set message = '<h3>foo</h3>' %}
{# a variable translated via a filter is escaped by default #}
{{ message|trans|raw }}
{# but static strings are never escaped #}
{{ '<h3>foo</h3>'|trans }}
I'm looking for a tag which would enable me to stop interpreting in a section, in a template.
So I'm looking for something that is similar to smarty's literal tag.
Thanks
I think you're looking for {% verbatim %} / {% endverbatim %}. In earlier versions these were called {% raw %} / {% endraw %}.
See also Twig Escaping.
In Twig, it is now verbatim, see http://twig.sensiolabs.org/doc/tags/verbatim.html
