Attributes support is broken/incompatible with fenced code blocks

See original GitHub issue

Attributes added to fenced code blocks are not applied to HTML.

Additionally they just break PlantUML support in the preview (which is actually my use-case. I need to be able to add attributes to plantuml code-blocks as I convert my Markdown using pandoc.

Examples

The attribute is ignored: ```lang {style=“border: 2px solid #000”} echo 42; ```

This breaks PlantUML preview: ```plantuml {caption=“Some text”} Some puml code ```

Ideally, attributes should be supported on code blocks. If that’s not possible if would be great if, at least, there were just ignored by the PlantUML support code so they don’t break the preview anymore.

@skalpa-rld, the issue for plantUML rendering of fenced code blocks is a bug in the plugin recognition of plant uml and other special code fenced blocks. The rendering uses the first word of the info string to generate the HTML class attribute but the code uses the whole string. I will fix this.

The attribute coming after the fenced code is an issue for CommonMark which does not have a limitation on the info string. So anything can be used for the info string. I will see if I can add handling of attributes after the info string (as being the tail end of the info string) so that attributes can be added after it.

I will fix it shortly and make an EAP release with the fix.

@vsch I can confirm that the fixes in the latest EAP work as expected, so I’m closing this issue.

Thanks a lot.
