Add support for Nix, Typst, and Vhdl

[WiredMic]

I have tested all of them.

Any chance you can get those modes to add support for EditorConfig instead?

If nix-ts-mode followed the convention of using FOO-indent-offset (instead of FOO-mode-indent-offset), your patch would not be needed. So I suggest a bug report to the nix-ts-mode maintainers.

I have send a bug report upstream.

Hi Stefan, I'm a committer on nix-ts-mode, and I could conceivably help get this changed via aliasing and deprecation, but I've seen the same pattern in other popular modes out there, e.g. toml-ts-mode. It seems strange to require the -mode- not to be there, as that is a reasonable part of a variable name. I personally think it would be better to adjust the heuristic here.

Why do you have (vhdl-indent-tabs-mode . ,indent-tabs-mode) here?
As for vhdl-basic-offset it should be auto-discovered by editorconfig--default-indent-size-function.

[WiredMic]

vhdl-indent-tabs-mode overrides indent-tabs-mode , so if it is not also set then it can override a configuration with space.

vhdl-indent-tabs-mode is a variable defined in ‘vhdl-mode.el’.

Its value is nil

Non-nil means indentation can insert tabs.
Overrides local variable ‘indent-tabs-mode’.

From line 4471.

      If option `vhdl-indent-tabs-mode' is nil, spaces are used instead of
    tabs.  \\[tabify] and \\[untabify] allow the conversion of spaces to
    tabs and vice versa.
