Dependencies per language:
| Language | Packages |
|---|---|
| bash | bash-language-server (npm) |
| c | clang >= 9, global (gtags) |
| cmake | cmake-language-server (pip) |
| elixir | erlang, elixir, elixir-ls |
| git | git |
| javascript | typescript-language-server (npm) |
| markdown | discount |
| python | python-language-server (pip) |
| ruby | solargraph (gem) |
| vue | vls (npm/yarn) |
Install the dependencies as shown by the table in Required Packages and
don't forget to tell emacs to look for binaries in their installation path:
;; Example of user installed language servers:
(setq exec-path
(append exec-path '(
"/home/user/.npm-packages/bin" ;; npm/yarn.
"/home/user/.gem/ruby/X.Y.Z/bin" ;; ruby gem.
"/home/rzalamena/.local/bin" ;; python/others.
)))Download and install somewhere a release of elixir-ls:
https://github.com/elixir-lsp/elixir-ls
Configure your emacs variable lsp-clients-elixir-server-executable to
point to the generated/installed language_server.sh file.
eslint >= 6 broke compatibility. The easiest fix is just to use version 5:
npm install -g eslint@5
npm install -g typescript-language-server typescript vlsnpm install -g bash-language-serverpip install --user cmake-language-serverTo use the ruby language server (solargraph) you need to install two gems:
# Either install as rvm, user or global.
gem install solargraph rubocopIf you are editing a project using the gem hierarchy (e.g. bin, lib
folders) you are going to need a <project>.gemspec file to your workspace
in order for solargraph to find your files.
Here is a sample:
# frozen_string_literal: true
$LOAD_PATH.unshift "./lib"
Gem::Specification.new do |s|
s.name = 'project-name'
s.version = '0.0.1'
s.license = 'license'
s.summary = 'summary'
s.authors = ['author 1']
s.email = 'your@mail'
s.files = ['lib/**/*.rb']
s.executables = ['your-executable]
# s.extensions = ['ext/<extension>/extconf.rb']
# s.homepage = 'https://yousite.you'
endSpell checker configuration has been moved to custom.el to allow
changing this setting without creating unstaged changes.
Spell check configuration example for Brazilian Portuguese and American English:
;; Spell checker: to use this you have installed the `hunspell' package.
(require 'ispell)
(setq ispell-program-name "hunspell"
ispell-dictionary "en_US,pt_BR")
(ispell-set-spellchecker-params)
(ispell-hunspell-add-multi-dic "en_US,pt_BR")When working with a complex C project (e.g. with command-line definitions
-DFOO_BAR or different include paths -I/new/headers) you might need
to instruct the compiler/analyzer some additional parameters.
If your compile tools (e.g. Makefile, cmake or other) don't support or can't generate a compilation database you might try using Bear.
# Example:
cd your-project
make clean
bear make -j16
# Now you have a `compile_commands.json` file.If flycheck complains about missing header or you need to supply a definition:
((c-mode . (
;; Include paths are relative to the open file.
(flycheck-gcc-include-path . ("." "../" "../secret-headers"))
(flycheck-clang-include-path . ("." "../" "../secret-headers"))
;; Tell the compiler about the makefile guards.
