No highlightjs JS/CSS files are added to the pages

Hi @shinkula, can you verify if changing the HTML code block to XML will add the JS/CSS?

Also, verify if it works for you with another language, such as PHP? Try placing only a PHP block of code in the page content.

HTML is a non-aliased language within the Highlight JS library. Use XML instead. I am working to come up with a better solution.

Hi @nmangold I checked again with XML and PHP block but it does not make any differences. The main issue is, Drupal unable to import necessary highlightjs JS/CSS files in the pages to make it work.

However, if i manually import the highlightjs JS/CSS libraries by configuring the *.libraries.yaml file everything works as expected.

highlightjs:
  version: 1.0.0
  js:
    /libraries/highlightjs/highlight.min.js: {}
    /libraries/highlightjs/highlightjs-copy.min.js: {}
    /libraries/highlightjs/invoke-highlight.js: {}

  css:
    component:
      /libraries/highlightjs/highlightjs-copy.min.css: {}
      /libraries/highlightjs/default.min.css: {}

@shinkula, I tested the module against Drupal 10.2.4 specifically using the steps you outlined to reproduce. Also, I am using it on several sites, and I know it does work as expected.

So, I am trying to figure out what is the scenario that does not work correctly for you. Have you tested against a vanilla Drupal install?

Can you debug what is happening in the file at web/modules/contrib/highlightjs_input_filter/src/Plugin/Filter/HighlightJs.php? The libraries are attached dynamically. Also, view web/modules/contrib/highlightjs_input_filter/js/highlightjs_input_filter.js to see how the language and copy button scripts are registered with hljs.

Unfortunately, I will need more information about how to reproduce the problem you are experiencing.

Hi @nmangold , I tested highlightjs input filter in a separate installation of Drupal 10.2 and it worked.
I am not sure why the same steps does not include necessary highlightjs JS/CSS files in the staging site.
Since the site is staging, i don't have too much options for debugging.
I will let you know about debug details whenever i get a chance to do so.
Thanks

Since this issue cannot be reproduced using a vanilla Drupal installation, it seems this is specific to your project. I am closing this issue. Feel free to add more details when those are available. Thanks.
