Pull request overview
This PR improves Markdown fenced code block language detection by normalizing the fenced “info string” so syntax highlighting works when the language is followed by common filename/option suffixes (eg js:app.ts, js,ignore, js ignore).
Changes:
- Add an AST transformer for
ast.FencedCodeBlocknodes that truncates the info string at the first separator (' ',',',':') so only the language remains. - Wire the new transformer into the existing Goldmark AST walk.
- Add unit tests covering several fenced code block info-string variants.
