From what I can tell Alastair is using conf-mode, not toml-ts-mode. Alastait: toml-ts-mode is a new builtin tree-sitter based major-mode for working with TOML files. If you have issues with conf-mode and certain TOML files, you could try that instead. I just tried it with your test-files and I don't see any incorrect fontification, so it seems to work fairly well. Eli: If there's a bug to fix in conf-mode, I'm going to assume it would be better to CC the conf-mode maintainer than the toml-ts-mode maintainer. It might gain more traction. — Kind Regards Jostein Kjønigsen > On 14 Apr 2024, at 21:59, Alastair Irving wrote: > > > On 14/04/2024 17:46, Eli Zaretskii wrote: >>> Date: Sun, 14 Apr 2024 11:25:08 +0100 >>> From: Alastair Irving >>> >>> When editting TOML files with conf-mode[toml] the face property is being >>> set badly on certain characters.

I think an extra newline was inserted in the TOML I pasted (in the comment before the URL), it should be 4 lines total. I've attached the exact file. >> >> Jostein and Yuan, can you please look into this? >
