Hi, since we recently discussed editor support and syntax highlighting: Pandoc can use definitions from Kate[1] for syntax highlighting in a code block via "--syntax-definition". There’s also ConTeXt support (MkIV/LMTX): https://kate-editor.org/syntax/data/syntax/context.xml Apparently, it can switch contexts to Lua, XML, MetaPost etc. But the list of commands is quite short. In case the author (Philipp A.) is listening: Is this intentional (“not necessary, highlight everything that starts with a backslash”)? Otherwise it probably would make sense to read in the interface files (i-*.xml). I can’t tell if it would make sense to support this syntax via a module (like scite and vim). What we have if probably enough for most of us. Hraban [1] List: https://kate-editor.org/syntax/ Specs: https://api.kde.org/frameworks/syntax-highlighting/html/
