Prism twig makes eleventy build fail

[jan-dh]

Describe the bug
I'm using 11ty/eleventy-plugin-syntaxhighlight to highlight code with prism in a .md file.
When trying to highlight twig syntax, eleventy fails to build and I get:

> Having trouble rendering liquid (and markdown) template ./src/posts/test-post.md

`TemplateContentRenderError` was thrown
> Having trouble compiling template ./src/posts/test-post.md

`TemplateContentCompileError` was thrown
> tag set not found, file:./src/posts/test-postmd, line:12

`ParseError` was thrown
> tag set not found

`AssertionError` was thrown:
    AssertionError: tag set not found
     ....

I'm assuming this is because I'm trying to output this:

....
{% set url = lang.getBaseUrl() %}

To Reproduce
Steps to reproduce the behavior:

1. Install eleventy-plugin-syntaxhighlight
2. paste this in a markdown file:

{% set test = 'test '% }

3. See error

Expected behavior
I would expect that everything in prism tags gets ignore and is not interpreted as actual code

Environment:

• MacOS Catalina 10.15.7
• Eleventy Version 6.14.4

@jan-dh what templating language are you using (eg. liquid, njk)? Also, can we get a link to the problematic code?

[jan-dh]

Managed to solve this by switching from .ejs to .njk. Issue was with .ejs, don't have the code live anywhere I'm afraid. Did start of from https://github.com/ixartz/Eleventy-Starter-Boilerplate, so that might be a good place to test it on.

For future folks, if the syntax you’re trying to highlight conflicts with the syntax of the parent template, many template languages have a raw output feature. Wrap your syntax highlighted block of code with the raw tag!
