Need some help with configuring indentation prefs

[valueof]

Just started using Helix, enjoying it so far. I'm having trouble configuring my indentation prefs. Specifically, I want TypeScript/JavaScript files to only use two spaces for indentation. I feel like I might be not understanding something about how Helix approaches language-specific indentation.

My configs are as follows:

❯ cat ~/.config/helix/config.toml
theme = "onedark"

❯ cat ~/.config/helix/languages.toml
[[language]]
name = "typescript"
indent = { tab-width = 2, unit = "  " }  # two spaces

[[language]]
name = "tsx"
indent = { tab-width = 2, unit = "  " }  # two spaces

[[language]]
name = "javascript"
indent = { tab-width = 2, unit = "  " }  # two spaces

If I create an empty .ts file it works fine. In the example file, when cursor is on { below pressing o will move it into the next line with two space indent.

function test() {
}

But if I open any existing file in our repo, the indentation reverts to four spaces. I recorded a video:

hx-tab.mov

Any help or pointers would be greatly appreciated!

The mystery deepens as this seems to work on my personal laptop running Arch but not on my work laptop running macOS. Same version in both:

❯ hx --version
helix 25.07.1 (a05c151b)

I figured it out! The project had an .editorconfig file which I wasn't aware of:

# editorconfig.org
root = true

[*]
indent_style = space
tab_width = 2
end_of_line = lf
charset = utf-8
trim_trailing_whitespace = true
insert_final_newline = true

[*.{json,yml,eslintrc,md,config}]
indent_style = space
indent_size = 2

[*.{md}]
trim_trailing_whitespace = false⏎

As you can see, it defines indent_style but not indent_size. Reading helix-core/src/editor_config.rs (forgive me, I'm not a Rust programmer) it seems that the logic is:

1. If indent_size is number then use that
2. If indent_size is tab (?) then use tab_width
3. Otherwise, default to 4.

I'm not sure why Helix defaults to 4 instead of languages.toml or its default config, but that's a story for another time.

Where is this .editorconfig file and how do you customize it? I can't seem to get mine to work!

Nevermind! forgot to enable editor-config = true in the editor section of the main helix config!
