I got it. Because markdown parser will translate
_..._to<em>...</em>. It should be configured to disableemin options:upupming commentedon Oct 25, 2018
Currently, you parse your math formula with KaTeX, and give the result to
docsify's renderer, so the math formula will be rendered again.Your fix is also not a good idea, because:
_..._syntax in the math formula, which cannot be implemented in the current renderer.*...*, which have special meaning in both KaTeX and markdown, but you means it is KaTeX syntax) you need to skip rendering withdocsify's renderer.I'm working on a plugin docsify-katex for writing KaTeX with
docsify, but it doesn't very stable yet. Although all KaTeX and markdown are rendered as expected, the sidebar doesn't show as expected.Update: The sidebar issue has been fixed.
