Colorscheme not applied until after a buffer is opened

[ckt114]

I've only started noticing this when I use goolord/alpha-nvim that the colors from the color scheme does not get applied until after a buffer is opened or start nvim with a buffer param. Below are the screenshots of before and after of the kanagawa theme. Is there a way for me to load all the highlights on VimEnter? TIA.

Running nvim without a buffer and run :Alpha

After opening a buffer or start vim with a buffer like nvim file.

@ckt114 check our extended_integrations option in core/default_cofnig.lua and add alpha to it

then load the alpha hl group by

dofile(vim.g.base46_cache .. "alpha") put it in custom/init.lua, i'll add docs for this tomorrow

@siduck Do I need to do anything after adding those lines? I did it and I get error below. I checked the path /Users/ckt114/.local/share/nvim/nvchad/base46 and there's no alpha file in there.

Error detected while processing /Users/ckt114/.config/nvim/init.lua:
E5113: Error while calling lua chunk: cannot open /Users/ckt114/.local/share/nvim/nvchad/base46/alpha: No such file or directory

So I had to delete ~/.local/share/nvim and ~/.local/state/nvim and restart nvim for it to run the bootstrap again and it created that /Users/ckt114/.local/share/nvim/nvchad/base46/alpha file and the error goes away but it still didn't work. I did add lines below into respective files.

custom/chadrc.lua

M.ui = {
  ...
  extended_integrations = { "alpha" },
  ...
}

custom/init.lua

  ...
  dofile(vim.g.base46_cache .. "alpha")

works for me, watch the video

Do you mind pasting the content of how you include alpha in custom/plugins.lua? Mine is below. I did remove the event = "VimEnter" as well but still not working. Also tried cmd = "Alpha" but no dice.

{
  "goolord/alpha-nvim",
  event = "VimEnter",
  requires = { "nvim-tree/nvim-web-devicons" },
  config = function()
    local startify = require "alpha.themes.startify"
    require "alpha".setup(startify.config)
  end,
}

[ckt114]

So I checked the highlights like you did and it showed that the colors alpha won't be correct until :Telescope is ran. You run :Alpha right after entering nvim, don't run :Telescope, and you'll see it's not coloring right for the theme.

our hl groups dont apply because you're using default alpha config

we just define 2 highlight groups for alpha, i'd suggest creating your own , put them into hl_add field of the UI field in chadrc. Read our themeing docs properly

[ckt114]

@siduck What I mean is why doesn’t nvchad load the theme correctly for alpha? I’m not customizing alpha colors, just want it to take whatever color the current theme gives it. You see in my two screenshots above that the first one is when I start nvim and the second one is after I opened a buffer or telescope then open alpha. It’s fine if this is not something that’s solvable. I use alpha with AstroNvim and LazyVim and they work fine for alpha but not NvChad.

did you even run the compiled cache for alpha? No :/

[siduck]

alpha isnt even used by nvchad so i put it in the extended integrations dir so users who want it can include it in chadrc and load its hl group by dofile .

Because in the future there will be tons of support for external plugins and then it would be too heavy to load all hl groups when we reload the theme, so we reload only what we & user needs

[ckt114]

Ok that’s fine. Not a bit deal. I can live with it. Maybe I’ll do some autocommand hack to start telescope first and then run alpha so it’ll load the color correctly.

dude all you have to do is run that dofile code in your custom/init.lua, is that hard? :angry:

[ckt114]

I did. It doesn’t work.

its hard to believe

works for me, watch the video

watch it, a clear proof that it works

[siduck]

please save your chadrc after added alpha to extended_Integrations, or else it wont compile And please use only neovim to edit your custom files or else none of our base46 stuff would recompile

[ckt114]

Yes and yes. I did save it and I only use neovim. You never ran :Alpha in that video of yours. Open neovim, run :Alpha, note the colors, run :Telescope, quit telescope, and run :Alpha again.

works for me?

[siduck]

did you even define our highlight groups in your alpha config? No

[ckt114]

Ok let’s forget about it.

[siduck]

Ok wait i see what you mean now

[siduck]

after selecting the theme with telescope

[siduck]

seems like alpha's taking hl groups from some of our non default hl groups

our telescope theme switcher loads all hl groups so alpha looks normal too ig

we should see which hl groups alpha uses

[siduck]

yea they use syntax hl groups

[siduck]

so just add this in your alpha config function

dofile(vim.g.base46_cache .. "syntax")

[siduck]

I'll try to add startify alike dashboard theme for our current dashboard in nvchad v3.0

[ckt114]

Ok I’ll try your suggestions. Thank you.
