• Via Home Manager

Using Home Manager, you can use the github url as an input and pass it to your nvim config.

Set ecsls.packages.${conf.system}.default within the neovim.extraPackages option and refer to the neovim configuration after the dependencie section.

• Development packages are provided throught nix develop.

• Install banana-vera package if existing, or you compile it by yourself.

You need to clone the repo of the coding style of EPITECH. If you do not have access to this repo, we are sorry but you will not be able to use this LSP, as it is required for this to run, and is internal to Epitech.

git submodules update --init --recursive

or

git clone https://github.com/Epitech/banana-coding-style-checker.git <path>

(optional) Create a virtual environement (avoid polluting your python).

python -m venv venv

Install the package locally.

venv/bin/pip install .

Note If you are using virtual environments, don't forget to add the correct path for the command in your LSP config

To activate ecsls as a language server, you'll need to create a custom LSP in your editor.

Once it is done, you'll need to create a ecsls.toml to tell the LSP to run as it is quite heavy and can be annoying.

To activate the language server using lspconfig, use the following configuration:

local lspconfig = require('lspconfig')
local configs = require('lspconfig.configs')

-- ↓ Epitech C Style Checker
if not configs.ecsls then
  configs.ecsls = {
    default_config = {
      root_dir = lspconfig.util.root_pattern('.git', 'Makefile'),
      cmd = { 'ecsls_run' },
      autostart = true,
      name = 'ecsls',
      filetypes = { 'c', 'cpp', 'make' },
    },
  }
end
lspconfig.ecsls.setup({})

(require 'lsp-mode)
(lsp-register-client
  (make-lsp-client :new-connection (lsp-stdio-connection '("ecsls_run"))
                   :major-modes '(c-mode c++-mode makefile-mode)
                   :server-id 'ecsls))

(add-hook 'c-mode-hook 'lsp)
(add-hook 'c++-mode-hook 'lsp)
(add-hook 'makefile-mode-hook 'lsp)

Note If you want to use it globally, or if you wish to change the vera rules directory, change path in by using init_options.

init_options = {
  path = '/your/custom/path',
},

Warning The path must be valid and pointing to the epitech ruleset repository root.

path = ".../ls/banana"  # invalid
path = ".../ls/banana-coding-style-checker/vera"  # invalid too
path = ".../ls/banana-coding-style-checker"  # valid
