Change tabstop and shiftwidth depending on language/filetype

[NorseManGef]

How would one use different tab lengths depending on the file type? for example, use 4 spaces for C++ while using 2 spaces for nix.

you can either:

• write your config into a ./config/ftplugin/cpp.lua

  vim.bo.tabstop = 4

  then add ./config to vim.additionalRuntimePaths

  (see :h ftplugin if you're not familiar with that)

• add an autocmd (untested code):

  vim.autocmds = [
    {
      event = "FileType";
      pattern = "cpp";
      callback = lib.generators.mkLuaInline ''
        function() vim.bo.tabstop = 4 end
      '';
    }
  ]

which you choose is down to your own preference
