sg.nvim

Status: Beta

Setup
Installation
Configuration

sg.nvim is a plugin focused on bringing many of the features of sourcegraph.com into Neovim.

Setup

To configure logging in:

Log in on your Sourcegraph instance.
Click your user menu in the top right, then select Settings > Access tokens.
Create your access token, and then run :SourcegraphLogin in your neovim editor after installation.
Type in the link to your Sourcegraph instance (for example: https://sourcegraph.com)
And then paste in your access token.

An alternative to this is to use the environment variables specified for src-cli.

You can check that you're logged in by then running :checkhealth sg

Installation

Requirements

Requires:

nvim 0.9 or nvim nightly
Node.js >= 18.17.0 (LTS) at runtime for cody-agent.js

(By default, sg.nvim downloads released binaries from Github. If you prefer to build the plugin yourself, you'll need cargo to build)

Currently uses plenary.nvim and telescope.nvim for some features.
- If you would like to use something else for search functionality, please make an issue and I can look into adding support.

Install

lazy.nvim

-- Use your favorite package manager to install, for example in lazy.nvim
--  Optionally, you can also install nvim-telescope/telescope.nvim to use some search functionality.
return {
  {
    "sourcegraph/sg.nvim",
    dependencies = { "nvim-lua/plenary.nvim", --[[ "nvim-telescope/telescope.nvim ]] },

    -- If you have a recent version of lazy.nvim, you don't need to add this!
    build = "nvim -l build/init.lua",
  },
}

packer.nvim

-- Packer.nvim, also make sure to install nvim-lua/plenary.nvim
use { 'sourcegraph/sg.nvim', run = 'nvim -l build/init.lua' }

-- You'll also need plenary.nvim
use { 'nvim-lua/plenary.nvim' }

-- And optionally, you can install telescope for some search functionality
--  "nvim-lua/plenary.nvim", --[[ "nvim-telescope/telescope.nvim ]]

vim-plug

" Using vim-plug
Plug 'sourcegraph/sg.nvim', { 'do': 'nvim -l build/init.lua' }

" Required for various utilities

(Nix instructions at the end of the readme)

Configuration:

-- Sourcegraph configuration. All keys are optional
require("sg").setup {
  -- Pass your own custom attach function
  --    If you do not pass your own attach function, then the following maps are provide:
  --        - gd -> goto definition
  --        - gr -> goto references
  on_attach = your_custom_lsp_attach_function
}

" Example mapping for doing searches from within neovim (may change) using telescope.
" (requires telescope.nvim to be installed)
nnoremap <space>ss <cmd>lua require('sg.extensions.telescope').fuzzy_search_results()<CR>

Nix(OS)

The project is packaged as a Nix Flake. Consume it as you normally would. For reference, see:

sg = let
  system = "x86_64-linux";
  package = inputs.sg-nvim.packages.${system}.default;
in {
  inherit package;
  init = pkgs.writeTextFile {
    name = "sg.lua";
    text = ''
      return function()
        package.cpath = package.cpath .. ";" .. "${package}/lib/?.so"
      end
    '';
  };
};

For Nix contributors and maintainers:

Feel free to nix flake update every once in a while to make sure flake.lock is up-to-date
