How to escape curly bracket "{" in TYPO3 Fluid template? - typo3

Question

I've a mixed HTML / JS template, when I'm working with JS arrays, Fluid tries to make autosubstitutions.
Is there a way to escape curly brackets in Fluid template ?
UPD :
Actual working syntax to escape JS parts is :
<script type="text/javascript">/*<![CDATA[*/
/*]]>*/
var llKeyOne = '{f:translate(key:"key1")}';
var llKeyTwo = '{f:translate(key:"key2")}';
/*<![CDATA[*/
var myTranslations = {
llKeyOne: llKeyOne,
llKeyTwo: llKeyTwo
};
/*]]>*/</script>

Answer 1

Try to use
<![CDATA[...]]>
tags around your JS code.

Answer 2

The CDATA solution stopped working in 8.7
I managed to solve the problem using alias in a usecase that heavily mixes javascript and fluid. {l} stands for left (open curly bracket) and {r} stands for right (close curly bracket):
<f:alias map="{l: '{', r: '}'}">
var alter = {};
<f:for each="{alterDB}" as="a">
if (!alter[{a.einsatz}]) { alter[{a.einsatz}] = {}; }
alter[{a.einsatz}][alter[{a.einsatz}].length] = {l} label: "{a.bezeichnung} ({a.kuerzel})", value: {a.uid} {r};
</f:for>
</f:alias>

Since it didn't worked for me in TYPO3 v8.7.16 with the <![CDATA[]]> solution above, I wanted to share my own solution. My "hack" to escape the brackets is to wrap those with a <f:format> viewhelper.
My goal was to output this in the frontend (400 and swing are fluid variables):
<ul data-animate="{duration:400, easing:'swing'}">
...
</ul>
I did this in the Fluidtemplate and it worked perfectly:
<ul data-animate="<f:format.raw>{</f:format.raw>duration: {data.myfield1}, easing:'{data.myfield2}'<f:format.raw>}</f:format.raw>">
...
</ul>

Solution working in TYPO3 9.x / 9.5.x
To avoid too much markup around curly braces which has a "not so nice" impact on the summary markup (readability and IDE support / highlighting) here an additional solution.
Possible limitation:
In our case the fluid template only contained fluid template variables within the templates head section followed by the entire markup which is processed/rendered by angular.js.
So we've created a partial for the angular.js part and included those inside the main fluid template.
Example:
The included partial file now starts using a {parsing off} statement (see example below).
Partial (simplified):
{parsing off} <!-- This solved all our issues -->
<div ng-show="showSlider">
<div class="slider" data-test="slider-wrapper">
<div class="row">
<div class="slide-indicator-mask col-lg-12">
<div class="slider-scope page-{{firstSlide}}"></div>
</div>
</div>
</div>

Answer 5

Use a fluid-Variable to add "![CDATA[" into your script.
I use the the tag-notation of fluid in javascript, because the syntax-highlighting works better with it.
<script type="text/javascript">/*{startCDATA}*/
var llKeyOne = '<f:translate key="key1" />';
var llKeyTwo = '<f:translate key="key2" />';
var myTranslations = {
llKeyOne: llKeyOne,
llKeyTwo: llKeyTwo
};
/*{endCDATA}*/</script>
I solved the bracket-problem with TYPO3-fluid and angulars-expressions in my dynamic template in the same way
<f:alias map="{ang: {s: '{{', e: '}}'}}">
...
<div class="{ang.s}{class}-{subclass}{ang.e}">...
</f:alias>

The last answer helpt me insert the files public url of an YouTube Video in TYPO3 fluid template using Video-js with Video-js YouTube extension.
After adding an new video in fileadmin and posting {file.publicUrl} in fluid returns an error. wrapping it inside f:format will do the job!
<f:format.raw>{file.publicUrl}</f:format.raw>
This is the whole code for getting YouTube Videos:
<f:if condition="{file.originalFile.properties.extension} == 'youtube'
<video
id="vid1"
class="video-jS"
data-setup='{ "techOrder": ["youtube"], "sources": [{ "type": "video/youtube", "src": "<f:format.raw>{file.publicUrl}</f:format.raw>"}] }'
>
</video>
</f:if>

Maybe too late but I found also one funny solution.
When I was integrating google seach structured data I found there this settings which should go to the template
<meta itemprop="target" content="https://query.example.com/search?q={search_term_string}"/>
And this is the easiest way I found for integration there
<meta itemprop="target" content="https://query.example.com/search?q={<f:format.raw>search_term_string</f:format.raw>}"/>

For the issue with a data attribute like
<ul data-animate="{duration:400, easing:'swing'}">
...
</ul>
the easiest solution I found was to simply swap single quotes and double quotes, like
<ul data-animate='{"duration":"400", "easing":"swing"}'>
...
</ul>
