Completor is an asynchronous code completion framework for vim8. New features of vim8 are used to implement the fast completion engine with low overhead. For using semantic completion, external completion tools should be installed.
- vim8,
- compiled with
pythonorpython3
- vim8 builtin package manager:
$ mkdir -p ~/.vim/pack/completor/start
$ cd ~/.vim/pack/completor/start
$ git clone https://github.com/maralla/completor.vim.git$ pack install maralla/completor.vimPlug 'maralla/completor.vim'When the input matches a file path pattern the file name will be automatically completed.
This is the fallback completer. When no semantic completer found the buffer completer will be used and will complete based on the current buffers.
Ultisnips is supported by default. If ultisnips is installed, the snips candidates will show on the completion popup menu.
Use this plugin completor-neosnippet for neosnippet support.
Neoinclude is supported by default. If neoinclude is installed, the include candidates will show on the completion popup menu.
Dictionary completion is supported by completor-dictionary.
You can add some complete functions with shell command by completor-shell.
Completion from words in tmux panes is supported by completor-tmux.
Completion from syntax file is supported by completor-necosyntax.
Use jedi for completion. jedi should be installed for semantic completion. Install jedi to global environment or in virtualenv:
pip install jediThe python executable can be specified using:
let g:completor_python_binary = '/path/to/python/with/jedi/installed'Use racer for completion. Install racer first. To specify the racer executable path:
let g:completor_racer_binary = '/path/to/racer'Use tern for completion. To install tern
you must have node and either npm or yarn installed. Then go to the completor.vim directory and run:
make jsThe node executable path can be specified using:
let g:completor_node_binary = '/path/to/node'If you're using vim-plug, you can just use post install hook to do this for you.
Plug 'ternjs/tern_for_vim', { 'do': 'npm install' }
Plug 'maralla/completor.vim', { 'do': 'make js' }
Use clang for completion. Clang should be installed first. To specify clang path:
let g:completor_clang_binary = '/path/to/clang'To pass extra clang arguments, you can create a file named .clang_complete under the project root directory or any parent directories. Every argument should be in a single line in the file. This is an example file:
-std=c++11
-I/Users/maralla/Workspace/src/dji-sdk/Onboard-SDK/lib/inc
-I/Users/maralla/Workspace/src/dji-sdk/Onboard-SDK/sample/Linux/inc
The key mapping <Plug>CompletorCppJumpToPlaceholder can be defined
to jump to placeholders:
map <tab> <Plug>CompletorCppJumpToPlaceholder
imap <tab> <Plug>CompletorCppJumpToPlaceholderUse gocode to provide omni completions. To specify the gocode executable path:
let g:completor_gocode_binary = '/path/to/gocode'Use completor-swift.
Use alchemist.vim.
Use completor-necovim.
Use completor-typescript.
For other omni completions completor not natively implemented, auto completion can still be used if an omni function is defined for the file type. But an option should be defined to specify the trigger for triggering auto completion. The option name pattern:
let g:completor_{filetype}_omni_trigger = '<python regex>'For example to use css omnifunc:
let g:completor_css_omni_trigger = '([\w-]+|@[\w-]*|[\w-]+:\s*[\w-]*)$'This is simple .tern-project file:
{
"plugins": {
"node": {},
"es_modules": {}
},
"libs": [
"ecma5",
"ecma6"
],
"ecmaVersion": 6
}inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <expr> <S-Tab> pumvisible() ? "\<C-p>" : "\<S-Tab>"
inoremap <expr> <cr> pumvisible() ? "\<C-y>" : "\<cr>"let g:completor_auto_trigger = 0
inoremap <expr> <Tab> pumvisible() ? "<C-N>" : "<C-R>=completor#do('complete')<CR>"A better way:
" Use TAB to complete when typing words, else inserts TABs as usual. Uses
" dictionary, source files, and completor to find matching words to complete.
" Note: usual completion is on <C-n> but more trouble to press all the time.
" Never type the same word twice and maybe learn a new spellings!
" Use the Linux dictionary when spelling is in doubt.
function! Tab_Or_Complete() abort
" If completor is already open the `tab` cycles through suggested completions.
if pumvisible()
return "\<C-N>"
" If completor is not open and we are in the middle of typing a word then
" `tab` opens completor menu.
elseif col('.')>1 && strpart( getline('.'), col('.')-2, 3 ) =~ '^[[:keyword:][:ident:]]'
return "\<C-R>=completor#do('complete')\<CR>"
else
" If we aren't typing a word and we press `tab` simply do the normal `tab`
" action.
return "\<Tab>"
endif
endfunction
" Use `tab` key to select completions. Default is arrow keys.
inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <expr> <S-Tab> pumvisible() ? "\<C-p>" : "\<S-Tab>"
" Use tab to trigger auto completion. Default suggests completions as you type.
let g:completor_auto_trigger = 0
inoremap <expr> <Tab> Tab_Or_Complete()Completor try its best to not overwrite the config completeopt, so the config
g:completor_complete_options is introduced to be the complete option when completor
is triggered.
let g:completor_complete_options = 'menuone,noselect,preview'If you explicitly set completeopt completor will not use this value for complete
options.
- Jump to definition
completor#do('definition') - Show documentation
completor#do('doc') - Format code
completor#do('format') - Hover info (lsp hover)
completor#do('hover')
noremap <silent> <leader>d :call completor#do('definition')<CR>

noremap <silent> <leader>f :call completor#do('format')<CR>
noremap <silent> <leader>s :call completor#do('hover')<CR>Use guru for jumping to definition:
let g:completor_go_guru_binary = 'guru'Use goimports to format code:
let g:completor_go_gofmt_binary = 'goimports'Format file after write to buffer:
autocmd BufWritePost *.go :call completor#do('format')Jump to completion placeholder:
map <c-\> <Plug>CompletorCppJumpToPlaceholder
imap <c-\> <Plug>CompletorCppJumpToPlaceholderDisable completion placeholder:

" Enable lsp for go by using gopls
let g:completor_filetype_map.go = {'ft': 'lsp', 'cmd': 'gopls'}
" Enable lsp for rust by using rls
let g:completor_filetype_map.rust = {'ft': 'lsp', 'cmd': 'rls'}
" Enable lsp for c by using clangd
let g:completor_filetype_map.c = {'ft': 'lsp', 'cmd': 'clangd-7'}
