Ability to add extra file extensions for a specific type

Describe the feature

I would love for the settings to allow specifying non-standard file extensions to a particular type. For example:

• (Elixir) Surface (.sface) files as the HTML type
• mix.lock as JSON type
• Dockerfile as Docker type (unsure this one is actually supported in Zed yet)

As a side note, it would be lovely if Elixir support included the ability to syntax highlight sigil content, including surface (~F, ~H), as most Phoenix Live View code includes rendered HTML inside sigils and it currently looks sad and hard to code.

If applicable, add mockups / screenshots to help present your vision of the feature

Hey @noozo, would either of these (or both) help to solve this issue for you? Having a settings area to apply one language's syntax highlighting to another:

• Allow manually setting a buffer language #5526 (and this comment specifically)
• Project-specific settings for including / excluding directories and files #5443

Associating specific files or types of files with a given language/language server seems to be covered by #5178, but not your Elixir-specific requests.

There's two parts to this:

• One, ability to associate, for instance .sface (Surface) as elixir/liveview (so that we would get syntax highlighting like we do in the sigil ~H (means we have HTML code inside an .ex file, as in LiveView)
• Two, ability to support other sigils, like Surface's ~F which is a variation of LiveView's ~H.

Hey @noozo, we now have support for this. You can add this setting to your settings.json file and map whatever you'd like:

"file_types": {
    "JSON": ["flake.lock"],
    "JSONC": ["**/.zed/**/*.json", "**/zed/**/*.json", "**/Zed/**/*.json", "tsconfig.json"]
},
