Fixed #698.
Currently, we display invisible text when the language specified for the code block is not recognized.
This is because in
MarkdownPreviewer.tsx: rehypeCodeMirrorAttacher()
, there is an edge case where if language is not null but there is no mime found for this language that can be found inCodeMirror.findModeByName
, we setnode.children
to[]
.Fix this case by returning early before the
node.children = cmResult
assignment.Tested with following languages after applying the change above:
java -> rendered with java highlighting
123f (made up language) -> rendered as plain text
(empty) -> rendered as plain text
