Integration with nvim-notify
![coc](https://user-images.githubusercontent.com/18579817/166508592-cc96612f-ca40-409d-9615-7880c790f5ad.png)
Add the following snippet to your init.vim
, after notify
extension is loaded and vim.notify
is pointing to require("notify")
.
lua << EOF
local coc_status_record = {}
function coc_status_notify(msg, level)
local notify_opts = { title = "LSP Status", timeout = 500, hide_from_history = true, on_close = reset_coc_status_record }
-- if coc_status_record is not {} then add it to notify_opts to key called "replace"
if coc_status_record ~= {} then
notify_opts["replace"] = coc_status_record.id
end
coc_status_record = vim.notify(msg, level, notify_opts)
end
function reset_coc_status_record(window)
coc_status_record = {}
end
local coc_diag_record = {}
function coc_diag_notify(msg, level)
local notify_opts = { title = "LSP Diagnostics", timeout = 500, on_close = reset_coc_diag_record }
-- if coc_diag_record is not {} then add it to notify_opts to key called "replace"
if coc_diag_record ~= {} then
notify_opts["replace"] = coc_diag_record.id
end
coc_diag_record = vim.notify(msg, level, notify_opts)
end
function reset_coc_diag_record(window)
coc_diag_record = {}
end
EOF

let l:info = get(b:, 'coc_diagnostic_info', {})
if empty(l:info) | return '' | endif

coc.nvim
uses echo* commands to write variety of messages. In order to intercept those, monkey patching it by utilizing vim's after
directory (see :help after-directory
) is one approach.
First, create coc/ui.vim
file in the autoload
after-directory in your vim's runtime path (e.g. ~/.vim/after/autoload
). For instance, place the following content in the file ~/.vim/after/autoload/coc/ui.vim
--
scriptencoding utf-8
if has("nvim")
" overwrite coc#ui#echo_messages function to use notify
function! coc#ui#echo_messages(hl, msgs)
if a:hl !~# 'Error' && (mode() !~# '\v^(i|n)$')
return
endif
let msgs = filter(copy(a:msgs), '!empty(v:val)')
if empty(msgs)
return
endif
" map a:hl highlight groups to notify levels
" if hl matches Error then level is error
" if hl matches Warning then level is warn
" otherwise level is info
let level = 'info'
if a:hl =~# 'Error'
let level = 'error'
elseif a:hl =~# 'Warning'
let level = 'warn'
endif
let msg = join(msgs, '\n')
call v:lua.coc_notify(msg, level)
endfunction
function! coc#ui#echo_lines(lines)
let msg = join(a:lines, "\n")
call v:lua.coc_notify(msg, 'info')
endfunction
endif
Next, manually source this file after coc.nvim has initialized. You can modify s:InitCoc
function from the previous example/section and add the function coc_notify
--
function! s:InitCoc() abort
" load overrides
runtime! autoload/coc/ui.vim
execute "lua vim.notify('Initialized coc.nvim for LSP support', 'info', { title = 'LSP Status' })"
endfunction
function coc_notify(msg, level)
local notify_opts = { title = "LSP Message", timeout = 500 }
vim.notify(msg, level, notify_opts)
end
