global indentation configuration

[nnym]

Indentation can be configured globally as shown below.

[editor.indent]
tab-width = 4
unit = "t"

These settings are used when a buffer is loaded and an indentation style is not detected and override language-specific defaults. However, they can be overridden per language in languages.toml by setting indent.required = true.

[[language]]
name = "yaml"
indent = {tab-width = 2, unit = "  ", required = true}

Setting indent.required = false for a language in the user's language.toml requires setting indent.{tab-width,unit} too but I think that this is out of the scope of this patch given that the same happens when setting indent.tab-width or indent.unit only.
These changes should resolve #3159.

Would be nice to try and merge this

Would really like this, annoying to have to keep setting it every time I open helix. It would be nice if there was some helix.rc or such so this wouldn't be a problem

Suggested change

	indent = { tab-width = 4, unit = " ", required = true }
	indent = { tab-width = 4, unit = " " }

Python allows using hard tabs for indentation (and actually any amount of spaces works too), it only disallows ambiguous mixing (i.e. when semantics depend on a specific tab width)

[nnym]

I didn't mark the indentation style as required because Python requires it; I did it in order to override the global setting for conformance with PEP 8.

[thecaralice]

I think required should only be applied to languages that do not support using tabs (like Nim) or spaces (like Makefile); everything else is basically just your stylistic choice which shouldn't affect anyone else. I mean, that's exactly the reason for using tabs instead of spaces.

[nnym]

I agree—I use tabs in Python and everywhere else—but this felt right to me at the time. In any case, I'll leave the decision to the maintainers.

Any updates on this?

So this won't be merged for now? We have to wait for plugin system to be implemented?
