@mpheath said: This is a markdown variant, AFAIK . Markdown has many variants so may seem like your problem is a variant that suits your needs. ASCIIDoc IIRC is a lexer that is not exposed in Notepad++ so perhaps wanted? This needs some more detail to know if the interest is desired. In interesting timing, I am actually in the middle of creating a HiddenLexer plugin (based on my old PythonScript solution) which will allow the plugin to activate lexers that Notepad++ doesn’t expose in the Languages menu. For alpha testing with ASCIIDoc: Download zip of plugin DLL from here: https://github.com/pryrt/NppPlugin-HiddenLexers/actions/runs/30941195491 (link should work for at least a few days) and put the DLL as c:\program files\notepad++\plugins\HiddenLexers\HiddenLexers.dll (or equivalent) %AppData%\Notepad++\plugins\config\HiddenLexers\HiddenLexers.json{ "extensions": { "adoc": "asciidoc" }, "lexers": { "asciidoc": { "0 SCE_ASCIIDOC_DEFAULT": { "fgColor": "", "bgColor": "", "fontStyle": "0" }, "1 SCE_ASCIIDOC_STRONG1": { "fgColor": "", "bgColor": "", "fontStyle": "1" }, "2 SCE_ASCIIDOC_STRONG2": { "fgColor": "", "bgColor": "", "fontStyle": "5" }, "3 SCE_ASCIIDOC_EM1": { "fgColor": "", "bgColor": "", "fontStyle": "2" }, "4 SCE_ASCIIDOC_EM2": { "fgColor": "", "bgColor": "", "fontStyle": "6" }, "5 SCE_ASCIIDOC_HEADER1": { "fgColor": "CC0000", "bgColor": "", "fontStyle": "1" }, "6 SCE_ASCIIDOC_HEADER2": { "fgColor": "CC3333", "bgColor": "4F4F4F", "fontStyle": "1" }, "7 SCE_ASCIIDOC_HEADER3": { "fgColor": "CC7777", "bgColor": "5F5F5F", "fontStyle": "1" }, "8 SCE_ASCIIDOC_HEADER4": { "fgColor": "CCbbbb", "bgColor": "6F6F6F", "fontStyle": "1" }, "9 SCE_ASCIIDOC_HEADER5": { "fgColor": "CCffff", "bgColor": "7F7F7F", "fontStyle": "1" }, "10 SCE_ASCIIDOC_HEADER6": { "fgColor": "FFFFFF", "bgColor": "8F8F8F", "fontStyle": "1" }, "11 SCE_ASCIIDOC_ULIST_ITEM": { "fgColor": "0000CC", "bgColor": "", "fontStyle": "0" }, "12 SCE_ASCIIDOC_OLIST_ITEM": { "fgColor": "0000CC", "bgColor": "", "fontStyle": "0" }, "13 SCE_ASCIIDOC_BLOCKQUOTE": { "fgColor": "00CC00", "bgColor": "", "fontStyle": "0" }, "14 SCE_ASCIIDOC_LINK": { "fgColor": "", "bgColor": "", "fontStyle": "4" }, "15 SCE_ASCIIDOC_CODEBK": { "fgColor": "00CC00", "bgColor": "", "fontStyle": "0" }, "16 SCE_ASCIIDOC_PASSBK": { "fgColor": "00CC00", "bgColor": "", "fontStyle": "0" }, "17 SCE_ASCIIDOC_COMMENT": { "fgColor": "00CC33", "bgColor": "", "fontStyle": "0" }, "18 SCE_ASCIIDOC_COMMENTBK": { "fgColor": "00CC33", "bgColor": "", "fontStyle": "0" }, "19 SCE_ASCIIDOC_LITERAL": { "fgColor": "CCCC00", "bgColor": "", "fontStyle": "0" }, "20 SCE_ASCIIDOC_LITERALBK": { "fgColor": "CCCC00", "bgColor": "", "fontStyle": "0" }, "21 SCE_ASCIIDOC_ATTRIB": { "fgColor": "CC00CC", "bgColor": "", "fontStyle": "0" }, "22 SCE_ASCIIDOC_ATTRIBVAL": { "fgColor": "CC00CC", "bgColor": "7F7F7F", "fontStyle": "0" }, "23 SCE_ASCIIDOC_MACRO": { "fgColor": "FFFF00", "bgColor": "", "fontStyle": "7" }, "options": {}, "keywords": [ "", "", "", "", "", "", "", "", "" ] } } } (the colors are reasonable in DarkModeDefault theme) The plugin isn’t ready for prime time yet, but for alpha testing, I was able to get that to automatically colorize the lexilla test asciidoc file AllStyles.adoc There’s no documentation for the plugin yet, nor an ABOUT box, nor any way to force it to re-read the JSON (those are all TODO). But as a proof of concept… [image: 1785870475625-9a9695a8-ab6a-4361-9c6c-6cb2ce36bab9-image.jpeg]
