Issue with file extension matching

[sethen]

Looks like nvim-web-devicons gets confused with you use more than one period for the extension in a file name. I would expect it to know that it should apply the same icon to .ts files as it does for test.ts files, but it doesn't. You have to add test.ts to the config or it will not apply. To make it work I have to do something like this:

return {
   'nvim-tree/nvim-web-devicons',
   dependencies = {
      'catppuccin/nvim',
   },
   config = function()
      local icons = require('nvim-web-devicons')
      local palette = require('catppuccin.palettes').get_palette('mocha')

      icons.setup({
         override = {
            ts = {
               color = palette.blue,
               icon = '',
               name = 'Ts',
            },
            ['test.ts'] = {
               color = palette.blue,
               icon = '',
               name = 'Test.ts',
            },
         }
      })
      icons.set_default_icon('')
   end,
}

Here's what it looks like if I would take the test.ts configuration out:

Are you sure it's a glyph from NF? Seems you're using a faulty codepoint.

Guess I don't understand how that would be a faulty codepoint? How does it work with .ts extensions but when test.ts is in the file it doesn't work?

[hasecilu]

I meant that in your snippet you used codepoint EA55 and in NerdFonts there is no associated glyph. If you got a "square" there it's because there is no glyph there.

I tried replacing the icons and works:

You're correct, there is no code point in NerdFonts. I use my own custom icon font and define the codepoints in Kitty (Terminal).

[sethen]

What you're seeing with the code point (EA55) is the same code point for the .ts files. So I am confused why it won't load the same icon for the same file extension.

[hasecilu]

I tried changing both extensions to the same char and also works. Not sure what could be happening on your end, maybe using override_by_extension makes a change.

@sethen Is that still an issue on your end?

Yes this is still an issue -- no matter what I try it does not work with nvim tree and web dev icons for overriding file extensions

[alex-courtis]

I've run a test to try and confirm the issue using nvim-tree's minimal configuration.

nvt-min.lua.gz

touch foo foo.ts foo.test.ts test.ts
nvim -nu nvt-min.lua

nvim-web-devicons setup commented out:

with setup:

@sethen I'd be grateful if you could point out whether the problem is reproduced and exactly which one is wrong.

-- icons for literally everything

return {
   'nvim-tree/nvim-web-devicons',
   dependencies = {
      'catppuccin/nvim',
   },
   config = function()
      local icons = require('nvim-web-devicons')
      local palette = require('catppuccin.palettes').get_palette('mocha')

      icons.setup({
         override = {
            yaml = {
               icon = '󰍰',
               name = 'Yaml',
            },
         }
      })
   end,
}

This does not work when I use it. I am using a unicode font that I patched myself which I included in this comment. I am using Ghostty to set the icon points appropriately and used font forge to make sure the code points don't collide. Mostly all icons work but not all of them.

With the code above "ts" works but "yaml" does not. I have noticed inconsistencies with other file extensions as well. This isn't just a nvim tree either, I have noticed that this behavior persists in telescope as well.

You can find the font here: https://github.com/sethen/dotfiles/blob/develop/assets/fonts/Sethens-Unicode.ttf

I tried the yaml override above and it is working as intended, showing the icon as expected:

Two possible problems and tests:

1. There is an issue with your terminal and font
   • Please change your terminal to a nerd font and test again
   • Please try a different terminal
2. There is a startup ordering issue; it looks like you might be using lazy which has nondeterministic startup ordering issues
   • Please test using the minimal reproducer which has fixed startup ordering Issue with file extension matching #483 (comment)

Okay so here's a good example of what I am talking about. It turns out the extensions are working for some things and not other things. As you can see the .yaml file extension works fine here. However the pnpm-lock.yaml file does not work correctly. This happens with quite a few files I have found as well. .ts may work but something like some_other_file.test.ts might not work (just an example).

Now you can fix this by setting an icon specifically for pnpm-lock.yaml in the setup but why should I have to do that? There are so many other yaml files and I don't want to define them all. pnpm-lock.yaml is also a problem in the minimal setup reproduction as well. So something weird is going on.

Okay so after some digging I found this: https://github.com/nvim-tree/nvim-web-devicons/blob/master/lua/nvim-web-devicons/light/icons_by_filename.lua#L167 -- how do I override these and tell devicons not use this rule for this file??
