Diagnostic messages disappear when save file

[kongjun18]

I use both ALE and coc.nvim(ccls) under the instructions of README. When I save file, all diagnostic messages disappear. coc.nvim seem to lint code when leave insert mode and change in normal mode. When I type some text and then exit insert mode or modify in normal mode, all diagnostic messages appear.

How could I make ALE keep diagnostic messages?

My ALE configuration:

let g:ale_disable_lsp = 1
let g:ale_linters_explicit = 1 " Disable other linters
let g:ale_lint_on_text_changed = 'never'
let g:ale_lint_on_insert_leave = 1
nmap <silent> gN <Plug>(ale_previous_wrap)
nmap <silent> gn <Plug>(ale_next_wrap)

I have this exact problem
My config is this one:

let g:ale_lint_on_text_changed = 'always'
let g:ale_fix_on_save = 1
let g:ale_fixers = {'javascript': ['prettier', 'eslint'], 'python': ['black', 'isort'], 'rust': ['rustfmt']}
let g:ale_disable_lsp = 1
let g:ale_set_highlights = 0
let g:ale_echo_msg_format = '[%linter%] (%code%) - %s'

let g:ale_linters_explicit = 1
let g:ale_linters = {'javascript': ['prettier', 'eslint'], 'python': ['flake8']}
let g:ale_lint_on_save = 1
let g:ale_lint_on_enter = 1

@kongjun18 did you get to fix this?

@w0rp is this known ?

Hi @kongjun18 , try setting those configs before loading ale plugin

@kongjun18 have you solved it yet?

I didn't solve it.

Please try using the bare minimum configuration to discard problems caused by conflicts with other plugings. For example I always keep this custom vimrc for testing:

call plug#begin('$HOME/.config/nvim/bundle')
Plug '$HOME/Projects/vim/ale'
call plug#end()

let g:ale_virtualtext_cursor = 1
let g:ale_fixers = { 'ruby': ['rubocop'] }
let g:ale_linters = { 'ruby': ['rubocop'] }

I change the linters, fixers, and add/remove other ale options depending on what I am testing. Then I run vim/neovim using this config alone on a sample HelloWorld for the language I am testing:

nvim -u vimrc  hello.rb

If you are not using vim-plug, instead use runtimepath to add the ale plugin:

let g:ale_completion_enabled = 1

set runtimepath=$VIMRUNTIME
set runtimepath^=$HOME/Projects/vim/ale

let g:ale_virtualtext_cursor = 1
let g:ale_linters = {'python': ['pyright']}

Note that some ale configurations must be set before the plugin is loaded. Check the help for details on each config you are planning to use.

Also providing the output of ALEInfo may allow other to help figuring out what may be wrong.

I set g:ale_lint_on_save = 0 and it works correctly. But when I set g:ale_lint_on_save = 1, after I save buffer, the signcolumn doesn't show errors when the linters detects errors
