Toml format highlight?
Not sure it is not implemented or just not detected in my path detection?
A Toml syntax definition isn't bundled with syntect by default, but you can easily add one as a consumer of the library. Ref: https://github.com/trishume/syntect/issues/168 https://packagecontrol.io/packages/TOML
See also: https://github.com/sublimehq/Packages/pull/4168
A quick skim shows it doesn't use branching or inheritance, so should be compatible 👍
Note that ST's new TOML syntax uses version: 2, which isn't supported yet according to https://github.com/trishume/syntect/issues/323.
