Available Layers » lsp

Description

This layers adds extensive support for language-server-protocol, This layer is a heavy wallpaper of LanguageClient-neovim (an old fork), The upstream is rewritten by rust.

We also include vim-lsp, which is written in pure vim script.

Note that if coc is used as autocomplete method in the autocomplete layer, it will be used as lsp client.

The neovim team is going to implement the build-in LSP support, the PR is neovim#6856. and the author of this PR create another plugin tjdevries/nvim-langserver-shim

SpaceVim should works well in different version of vim/neovim, so in the features, the logic of this layer should be:

if has('nvim')
  " use neovim build-in lsp
if SpaceVim#layers#isLoaded("autocomplete") && get(g:, "spacevim_autocomplete_method") ==# 'coc'
  " use coc.nvim
elseif has('python3')
  " use LanguageClient-neovim
else
  " use vim-lsp
endif

Features

Note: All these features dependent on the implementation of the language server, please check the list of Language Servers

Install

To use this configuration layer, update custom configuration file with:

[[layers]]
  name = "lsp"

Install language server

Bash

npm i -g bash-language-server

JavaScript:

npm install -g javascript-typescript-langserver

Python:

pip install --user python-language-server

julia:

The LanguageServer package must be installed in Julia (0.6 or greater), i.e.

julia> Pkg.clone("https://github.com/JuliaEditorSupport/LanguageServer.jl")

With new package system in Julia 0.7 and above, we have a package mode in Julia REPL. in REPL, hit ] to enter the package management mode, then add LanguageServer to install the package.

PureScript

npm install -g purescript-language-server

Vue:

npm install vue-language-server -g

css:

npm install -g vscode-css-languageserver-bin

ruby:

gem install solargraph

Configuration

To enable lsp support for a specified filetype, you may need to load this layer with filtypes option, for example:

[[layers]]
  name = "lsp"
  filetypes = [
    "rust",
    "javascript"
  ]

default language server commands:

language server command
c ['clangd']
cpp ['clangd']
css ['css-languageserver', '--stdio']
dart ['dart_language_server']
go ['go-langserver', '-mode', 'stdio']
haskell ['hie', '--lsp']
html ['html-languageserver', '--stdio']
javascript ['javascript-typescript-stdio']
julia ['julia', '--startup-file=no', '--history-file=no', '-e', 'using LanguageServer; server = LanguageServer.LanguageServerInstance(STDIN, STDOUT, false); server.runlinter = true; run(server);']
objc ['clangd']
objcpp ['clangd']
php ['php', 'path/to/bin/php-language-server.php']
purescript ['purescript-language-server', '--stdio']
python ['pyls']
ruby ['solargraph', 'stdio']
rust ['rustup', 'run', 'nightly', 'rls']
sh ['bash-language-server', 'start']
typescript ['typescript-language-server', '--stdio']
vue ['vls']

To override the server command, you may need to use override_cmd option:

[[layers]]
  name = "lsp"
  filetypes = [
    "rust",
    "javascript"
  ]
  [layers.override_cmd]
    rust = ["rustup", "run", "nightly", "rls"]

Key bindings

Key Binding Description
K / SPC l d show document
SPC l e rename symbol

if the checkers layer is not loaded, these key bindings will be added:

Key description
SPC e c clear errors
SPC e n jump to the position of next error
SPC e N jump to the position of previous error
SPC e p jump to the position of previous error
SPC e l display a list of all the errors
SPC e L display a list of all the errors and focus the errors buffer
