Vim and Neovim

Vim and Neovim are able to use the Julia LanguageServer via LanguageClient-neovim with completion from nvim-completion-manager.

The following is a basic minimal config (vimrc for Vim; init.vim for Neovim) using vim-plug:

call g:plug#begin()
  Plug 'JuliaEditorSupport/julia-vim'
  Plug 'autozimu/LanguageClient-neovim', {'branch': 'next', 'do': 'bash install.sh'}
  Plug 'roxma/nvim-completion-manager'  " optional
call g:plug#end()

" julia
let g:default_julia_version = '1.0'

" language server
let g:LanguageClient_autoStart = 1
let g:LanguageClient_serverCommands = {
\   'julia': ['julia', '--startup-file=no', '--history-file=no', '-e', '
\       using LanguageServer;
\       using Pkg;
\       import StaticLint;
\       import SymbolServer;
\       env_path = dirname(Pkg.Types.Context().env.project_file);
\       debug = false; 
\       
\       server = LanguageServer.LanguageServerInstance(stdin, stdout, debug, env_path, "", Dict());
\       server.runlinter = true;
\       run(server);
\   ']
\ }

nnoremap <silent> K :call LanguageClient_textDocument_hover()<CR>
nnoremap <silent> gd :call LanguageClient_textDocument_definition()<CR>
nnoremap <silent> <F2> :call LanguageClient_textDocument_rename()<CR>

Note:

1. The LanguageServer, SymbolServer and StaticLint packages must be installed in Julia (1.x), i.e.

   julia> using Pkg
   julia> Pkg.add("LanguageServer")
   julia> Pkg.add("SymbolServer")
   julia> Pkg.add("StaticLint")

2. If Julia (0.6 or greater) is not present in the PATH environment, either add the julia binary folder to PATH or directly reference the julia binary in g:LanguageClient_serverCommands, e.g. for macOS:

   let g:LanguageClient_serverCommands = {
   \   'julia': ['/Applications/Julia-0.6.app/Contents/Resources/julia/bin/julia', ...

3. See vim-plug for more details on installing/managing packages in Vim/Neovim

SpaceVim

SpaceVim have a layer to use LanguageServer.jl, the setup is automatic once you installed the Julia layer.
