NeoTree background does not blend with the WinSeparator as shown in README screenshots.

[UtkarshVerma]

Description

In the screenshots, the background of NeoTree and the window separator is the same which gives a consistent look to the sidebar. It can be achieved by setting the fillchar appropriately.

vim.opts.fillchars.vert = "▎", -- Used for window separator.

I have to use the following custom_highlight to fix it:

      custom_highlights = function(colors)
        return {
          -- Make window separator blend with neo-tree.
          WinSeparator = { fg = colors.mantle, bg = colors.none },
        }
      end,

Neovim version

NVIM v0.9.5 
Build type: Release 
LuaJIT 2.1.1702233742 
 
   system vimrc file: "$VIM/sysinit.vim" 
  fall-back for $VIM: "/usr/share/nvim" 
 
Run :checkhealth for more info

Terminal and multiplexer

st

Catppuccin version / branch / rev

Steps to reproduce

Just open neovim and observe the separator.

Expected behavior

Window separator color is same as NeoTree background.

Actual behavior

The border looks different.

on screenshot is nvimtree with

nvim/lua/catppuccin/groups/integrations/nvimtree.lua

Line 11 in c0de3b4

NvimTreeWinSeparator = {

neotree also has this like defined here

nvim/lua/catppuccin/groups/integrations/neotree.lua

Line 37 in c0de3b4

NeoTreeVertSplit = { fg = C.base, bg = inactive_bg },

but neotree catppuccin integration disabled by default (so just enable this integration in your config)

[UtkarshVerma]

I had the integration for neotree turned on. Here is the repro.lua for this if you want to test:

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
	vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
	{
		"catppuccin/nvim",
		main = "catppuccin",
		opts = {
			integrations = {
				neotree = true,
			},
		},
	},

	{
		"nvim-neo-tree/neo-tree.nvim",
		dependencies = {
			{ "MunifTanjim/nui.nvim" },
			{ "nvim-lua/plenary.nvim" },
			{ "nvim-tree/nvim-web-devicons" },
		},
	},
	-- add any other plugins here
}
require("lazy").setup(plugins, {
	root = root .. "/plugins",
})

vim.opt.fillchars = { vert = "▎" }
vim.cmd.colorscheme("catppuccin")
-- add anything else here

[mariesavch]

tested its working with NeoTreeWinSeparator hightlight

[UtkarshVerma]

So, would it be added upstream, or do I have to update my config?

[mariesavch]

for now you can use custom_hightlights
NeoTreeWinSeparator = { fg = colors.base, bg = colors.base }
