Support transparent backgrounds

[augustocdias]

Is it possible to add the possibility to add transparency or choose the color for the background? As you can see in the print bellow the background is quite different from the one from nvim.

For highlighting, I just link FidgetTask to LineNr and FidgetTitle to Title. Have you defined a background color for either of these?

You should now be able to override this highlight link following resolution of #6

I tried this & still can't get rid of background.

hi! FidgetTitle ctermbg=NONE guibg=NONE
hi! FidgetTask ctermbg=NONE guibg=NONE

[j-hui]

Tha's odd. I'm not doing anything in my plugin to define the background color. If anything, I'm setting winblend to 100, so there really should be no background.

A few questions:

What does running :hi FidgetTask and :hi FidgetTitle show?

What colorscheme are you currently using?

Have you set termguicolors? If not, does the problem still persist with set termguicolors?

[augustocdias]

I get FidgetTitle xxx links to Title and FidgetTask xxx links to NonText.

I'm using tokyo-night and termguicolors is set

[ahmedelgabri]

What does running :hi FidgetTask and :hi FidgetTitle show?

Same as @augustocdias

What colorscheme are you currently using?

I'm using https://github.com/andreypopp/vim-colors-plain

Have you set termguicolors? If not, does the problem still persist with set termguicolors?

Yes, I have it set.

Issue transfered from #6, probably related:

My fidget appears darker or brighter than the defined colors on different buffers. Here are the screenshots:

Setting winblend to 0 made my popup completely transparent. Kinda odd

edit: forgot to mention, line 123 is the relevant change

[j-hui]

23 (which superceded #22; thanks @axieax!) adds a window.blend option, among other things. Does this fix everyone's transparency issues?

[ahmedelgabri]

Yup, works fine for me. Thanks @j-hui

[folliehiyuki]

I set winblend = 0 and the colors seem ok now. Thanks!

[alex-popov-tech]

works for me with {'j-hui/fidget.nvim', config = function() require('fidget').setup({ window = { winblend = 0 }}) end}

For future reference if you have autocmd vimenter * hi Normal guibg=none guifg=none in your config to make vim have a transparent background it will also cause fidget to have a black background.

For now I just matched my terminal editors background autocmd vimenter * hi Normal guibg=#202020

Is anyone still running into this? Regardless of what I've tried with highlight groups and the winblend option, the colors always appear much darker in fidget than they are in the actual theme/highlight setting. The background is transparent, however.

Nevermind this, just read the comment below.

Original comment

Hi everyone! Like @prurph, I can also often reproduce this issue (same as @FollieHiyuki posted, with dimmed highlights in some buffers, even for same instance of LSP/fidget), so I think it should be reopened.

I've been trying to analyze it for some time now and here is my summary (it might be useful to someone):

• I'm fairly certain that this issue cannot be reproduced unless vim.opt.termguicolors = true is set. (I have set this option manually and the colorscheme I'm using also sets it internally. Unless I disable both the colorscheme AND my manual option, issue persists, even with default colorscheme.)
• Order of vim.opt.termguicolors = true and fidget setup doesn't seem to matter.
• In my experience, when issue is reproduced once (regardless of the used LSP and/or number of opened buffers), it is 100% reproducible by repeating the same thing over and over (i.e. opening Neovim with same files)
• Reproduction doesn't seem so consistent with different inputs, although it always looks the same visually.
  • When I open several (5-10) Lua files of my Neovim configuration, only first buffer has dimmed highlights for sumneko_lua LSP, while all others look as expected.
  • On the other hand, when I open 20+ C++ files with clangd, first few files always have correct fidget highlighting, while some of the later ones have dimmed highlighting.

While it also happened to me when opening just 1 Lua file with sumneko_lua LSP, I would suggest the following as best way to initially reproduce the issue:

• Make sure that your Lua configuration sets vim.opt.termguicolors = true.
• Optionally use default theme. (I don't think this matters, but it helps with narrowing the issue down.)
• Configure fidget to use default setup. (This should be easiest common ground for everyone and issue is reproducible with it.)
• Open all Lua configuration files for Neovim with sumneko_lua LSP. (Hopefully, this is something that all participants here have in common.)
• Quickly just browse through all of them with :bnext (or whatever keymap that is for you)
• Observer the fidget in the bottom right corner of the screen while browsing through files. Hopefully issue should be easily spotted.

[Iskustvo]

Silly me! After reading #32, it became more apparent. This issue actually happens when fidget is drawn below last line in file.

This makes reproduction easy:

• Position fidget at the bottom of the screen (also default).
• Open file which has all lines on the screen populated. Just empty lines are perfectly fine as long as there is something on the line (even just newline character).
• fidget should look as expected.
• Press G to jump at the bottom of the file.
• Press zz to center window to cursor position. This will position fidget below last line in the file.
• fidget will change colors when it finds itself below last line.

Maybe linking fidget highlights to some more persistent highlights (if there are such) by default would be better.

Still having a problem with this. Used everything below, but nothing happens. I would suggest just leaving blend as 0 in the future.

use({ "j-hui/fidget.nvim", config = function() require("fidget").setup({ window = { blend = 0, relative = "editor", }, }) end, tag = "legacy", })

Just in case anyone needs this - this is how I sorted the transparent background:

{
  "j-hui/fidget.nvim",
  opts = {
    notification = {
      window = {
        winblend = 0,
      },
    },
  },
},
