Is there a way to have Helix "remember" when I use :set-language on a particular file?

[ChrisRenfrow]

Sorry if this is documented someplace already, I wasn't able to find it if it is.

Sometimes a file doesn't have an extension but I want to edit it with syntax highlighting and/or formatting enabled. While I'm glad :set-language (or :lang) exists, it would be nice if the override would persist between sessions. I've seen this handled in other editors and I was curious if Helix had something similar I wasn't seeing.

Take a look here and the file-types key.

I had no idea file-types was so flexible. Thanks for the pointer!

For anyone else encountering this thread in the future, you can pass a list of tables to file-types with the key/column glob. Example from the docs (25.01.1):

file-types = ["toml", { glob = "Makefile" }, { glob = ".git/config" }, { glob = ".github/workflows/*.yaml" } ]

In my case, I'm trying to get JSON highlighting enabled for a particular config file that lacks the extension, so I'd add something like:

file-types = ["json", { glob = "~/.config/some-service/config" } ]

Thanks again @bojohnson5!
