Bug: (Extremely low priority) filetype component - Extra space after icon

[monr3d]

Self Checks

• I'm using the latest lualine.
• I didn't find the issue in existing issues or PRs.

How to reproduce the problem

Enable filetype component with icon only or align right

Expected behaviour

there shouldn't be and extra space after the icon or a to add/remove it



(this actually is fine)

Actual behaviour

there is an annoying (to me) space after the icon in the filetype module

Minimal config to reproduce the issue

require("lualine").setup({
    sections = {
        lualine_a = { { "mode" }, },
        lualine_b = { { "filetype", icon_only = true }, }
    },
}

Additional information

I'm not sure if there is a reason for the space or if it is the author design choice.
As you can see from the screenshot I already fixed for myself, but I don't want to have a fork just for that, if the change is welcome I can submit a PR as it is a very simple edit.
Although the screenshots show my config, I tried a few separators and the problem persist, if there is a case where it is useful i can be made optional.

This is the code responsible:

lualine.nvim/lua/lualine/components/filetype.lua

Lines 43 to 45 in b8c2315

	if icon then
	icon = icon .. ' '
	end

lualine.nvim/lua/lualine/components/filetype.lua

Lines 63 to 65 in b8c2315

	if icon then
	icon = icon .. ' '
	end

I'd assume that the space exists for the propo variant of nerdfonts. That one uses Icons that are 2 cells wide

[monr3d]

I did not consider that, I'll test my change with multiple fonts and report back.
If your assumption is correct, I need to add an option to choose.

[monr3d]

The propo variant was a good guess, with propo variant I had to add the space in some of the icon in other part of my config, but lualine filetype still look ok with my edit.

if anyone want to test it: https://github.com/monr3d/lualine.nvim

[monr3d]

On further testing, it appear that the space is there for the propo variant. When there is no other component on the same section it is not aligned, although I still believe it look better than with the space.
It is now a matter of preference or to add an option that add the space
