Changelog Entry
Description
Allows for custom attributes on code blocks through:
```html collapsed
<!-- code here -->
```
Supporting attributes:
collapsed will render the code block in a collapsed state by default.
hidden will prevent the code block from being displayed entirely.
This is useful for scenarios where we want to show interactive previews (charts or visual demos) without the user needing to see the underlying code.
Added
Added a marked extension to parse code blocks with custom attributes.
Support custom "collapsed" attribute to collapse code blocks by default.
Support custom "hidden" attribute to hide code blocks.
Changed
Replaced existing marked code block parsing with a custom marked extension.
Deprecated
None
Removed
None
Fixed
None
Security
None
Breaking Changes
None
Additional Information
I see that there's a setting to collapse code by default; however, this feature allows the model to make that decision.
The original setting remains unchanged and continues to function as expected alongside this feature.
