@ell1e I still think a dedicated JSON filetype should (at least by default) not allow comments. But we don't even need to make a hard decision here as the Scintilla JSON lexer has a property to toggle highlighting of comments: `lexer.json.allow.comments`.
So, one can add: ``` [lexer_properties] lexer.json.allow.comments=1 ``` to the filetype definition and so enable highlighting of comments if desired. @d5l6 this could go as commented and documented option in the filetype definition (for reference see https://sourceforge.net/p/scintilla/code/ci/default/tree/lexers/LexJSON.cxx#...).
