Here is an example with ALE and Neovim (tested with v0.3.8):
- Install the Ale plugin. If your Vim has support for packages (Vim 8+ or Neovim) you can simply clone it in the correct subdir, no need for a plugin manager:
git clone https://github.com/w0rp/ale.git .vim/pack/my-plugins/start/ale - Add this to your .vimrc:
" only invoke merlin to check for errors when
" exiting insert mode, not on each keystroke.
let g:ale_lint_on_text_changed="never"
let g:ale_lint_on_insert_leave=1
" enable ALE's internal completion if deoplete is not used
let g:ale_completion_enabled=1
" only pop up completion when stopped typing for ~0.5s,
" to avoid distracting when completion is not needed
let g:ale_completion_delay=500
" see ale-completion-completeopt-bug
set completeopt=menu,menuone,preview,noselect,noinsert
if has('packages')
packloadall
" This should be part of ALE itself, like ols.vim
call ale#linter#Define('ocaml',{
\ 'name':'ocaml-lsp',
\ 'lsp': 'stdio',
\ 'executable': 'ocamllsp',
\ 'command': '%e',
\ 'project_root': function('ale#handlers#ols#GetProjectRoot')
\})
" remap 'gd' like Merlin would
nmap <silent><buffer> gd <Plug>(ale_go_to_definition_in_split)<CR>
" go back
nnoremap <silent> <LocalLeader>gb <C-O>
" show list of file:line:col of references for symbol under cursor
nmap <silent><buffer> <LocalLeader>go :ALEFindReferences -relative<CR>
" Show documentation if available, and type
nmap <silent><buffer> <LocalLeader>hh <Plug>(ale_hover)<CR>
" So I can type ,hh. More convenient than \hh.
nmap , <LocalLeader>
vmap , <LocalLeader>
endif
