Automatically creates missing LSP diagnostics highlight groups for color schemes that don't yet support the Neovim 0.5 builtin lsp client.

• supports the latest Neovim 0.5 and 0.6 (HEAD) LSP highlight groups
• support any colorscheme like Nord and Gruvbox
• existing highlight groups from themes will never be overwritten
• tries to use coc.nvim groups if they are defined in the theme
• if not, we fall back to a default set of colors

• Neovim >= 0.5.0

Install the theme with your preferred package manager:

vim-plug

Plug 'folke/lsp-colors.nvim'

packer

use 'folke/lsp-colors.nvim'

Nothing special. Just load a colorscheme as usual 🙂

LSP Colors works out of the box, but you can set the default colors that will be used in case a theme doesn't have LSP nor Coc highlight groups.

-- Lua
require("lsp-colors").setup({
  Error = "#db4b4b",
  Warning = "#e0af68",
  Information = "#0db9d7",
  Hint = "#10B981"
})

To have undercurls show up and in color, add the following to your Tmux config file:

# Undercurl
set -g default-terminal "${TERM}"
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours - needs tmux-3.0
