tab-width ignored for C files

[tavianator]

Summary

I want literal tab characters to be rendered with width 8. But it seems they always get width 2.

Reproduction Steps

tavianator@graphene $ cat ~/.config/helix/languages.toml
[[languages]]
name = "c"
scope = "source.c"
injection-regex = "c"
file-types = ["c"]
indent = { tab-width = 8, unit = "\t" }
tavianator@graphene $ cat foo.c
int main(void) {
        return 0;
}
tavianator@graphene $ xxd foo.c
00000000: 696e 7420 6d61 696e 2876 6f69 6429 207b  int main(void) {
00000010: 0a09 7265 7475 726e 2030 3b0a 7d0a       ..return 0;.}.
tavianator@graphene $ helix foo.c

There's a typo in ~/.config/helix/languages.toml: the header should be [[language]] instead of [[languages]]

Argh thanks so much. Might be worth a warning?

[the-mikedavis]

I don't think it would be straightforward to add warnings or errors on unused keys because of the way we read languages.toml right now. (We read it once for the [[languages]] and [langauge-server] config and differently for the [[grammar]] entries.) We have plans to change how the grammars are specified though which will change that and in the long run we want to change how language configuration is defined entirely (#8853)
