gitlab.nvim

This Neovim plugin is designed to make it easy to review Gitlab MRs from within the editor. This means you can do things like:

• Read and Edit an MR description
• Approve or revoke approval for an MR
• Add or remove reviewers and assignees
• Resolve, reply to, and unresolve discussion threads
• Create, edit, delete, and reply to comments on an MR

And a lot more!

Requirements

• Go
• make (for install)
• delta

Quick Start

1. Ensure Dependencies (Linux/Mac users can run the install script: ./install)
2. Add config (below)
3. Check out feature branch
4. Open Neovim
5. Run :lua require("gitlab").review() to open the reviewer pane, or `:lua require("gitlab").summary() to read the MR description and get started.

Installation

With Lazy:

return {
  "harrisoncramer/gitlab.nvim",
  dependencies = {
    "MunifTanjim/nui.nvim",
    "nvim-lua/plenary.nvim",
    "stevearc/dressing.nvim", -- Recommended but not required. Better UI for pickers.
    enabled = true,
  },
  build = function () require("gitlab.server").build() end, -- Builds the Go binary
  config = function()
    require("gitlab").setup()
  end,
}

And with Packer:

use {
  'harrisoncramer/gitlab.nvim',
  requires = {
    "MunifTanjim/nui.nvim",
    "nvim-lua/plenary.nvim"
  },
  run = function() require("gitlab.server").build() end,
  config = function()
    require("gitlab").setup()
  end,
}

Configuration

This plugin requires a .gitlab.nvim file in the root of the project. Provide this file with values required to connect to your gitlab instance of your repository (gitlab_url is optional, use ONLY for self-hosted instances):

project_id=112415
auth_token=your_gitlab_token
gitlab_url=https://my-personal-gitlab-instance.com/

If you don't want to write your authentication token into a dotfile, you may provide it as a shell variable. For instance in your .bashrc or .zshrc file:

export GITLAB_TOKEN="your_gitlab_token"

Configuring the Plugin

Here is the default setup function. All of these values are optional, and if you call this function with no values the defaults will be used:

require("gitlab").setup({
  port = 21036, -- The port of the Go server, which runs in the background
  log_path = vim.fn.stdpath("cache") .. "/gitlab.nvim.log", -- Log path for the Go server
  reviewer = "delta", -- The reviewer type (only delta is currently supported)
  popup = { -- The popup for comment creation, editing, and replying
    exit = "<Esc>",
    perform_action = "<leader>s", -- Once in normal mode, does action (like saving comment or editing description, etc)
  },
  discussion_tree = { -- The discussion tree that holds all comments
    jump_to_file = "o", -- Jump to comment location in file
    jump_to_reviewer = "m", -- Jump to the location in the reviewer window
    edit_comment = "e", -- Edit coment
    delete_comment = "dd", -- Delete comment
    reply = "r", -- Reply to comment
    toggle_node = "t", -- Opens or closes the discussion
    toggle_resolved = "p", -- Toggles the resolved status of the discussion
    position = "left", -- "top", "right", "bottom" or "left"
    size = "20%", -- Size of split
    relative = "editor", -- Position of tree split relative to "editor" or "window"
    resolved = '✓', -- Symbol to show next to resolved discussions
    unresolved = '✖', -- Symbol to show next to unresolved discussions
  },
  review_pane = { -- Specific settings for different reviewers
    delta = {
      added_file = "", -- The symbol to show next to added files
      modified_file = "", -- The symbol to show next to modified files
      removed_file = "", -- The symbol to show next to removed files
    }
  },
  dialogue = {  -- The confirmation dialogue for deleting comments
    focus_next = { "j", "<Down>", "<Tab>" },
    focus_prev = { "k", "<Up>", "<S-Tab>" },
    close = { "<Esc>", "<C-c>" },
    submit = { "<CR>", "<Space>" },
  },
})

Usage

First, check out the branch that you want to review locally.

git checkout feature-branch

Then open Neovim. The project_id you specify in your configuration file must match the project_id of the Gitlab project your terminal is inside of.

The summary command will pull down the MR description into a buffer so that you can read it. To edit the description, edit the buffer and press the perform_action keybinding when in normal mode (it's <leader>s by default):

require("gitlab").summary()

The review command will open up view of all the changes that have been made in this MR compared to the target branch in a review pane. You can leave comments on the changes.

require("gitlab").review()
require("gitlab").create_comment()

Gitlab groups threads of comments together into "discussions."

To display discussions for the current MR, use the list_discussions() command, which will show the discussions in a split window.

You can jump to the comment's location the reviewer window by using the m key, or the actual file with the 'j' key, when hovering over the line in the tree.

Within the discussion tree, you can delete/edit/reply to comments, or toggle them as resolved or not.

require("gitlab").list_discussions()
require("gitlab").delete_comment()
require("gitlab").edit_comment()
require("gitlab").reply()
require("gitlab").toggle_resolved()

You can approve or revoke approval for an MR:

require("gitlab").approve()
require("gitlab").revoke()

The add_reviewer and delete_reviewer commands, as well as the add_assignee and delete_assignee functions, will let you choose from a list of users who are availble in the current project:

require("gitlab").add_reviewer()
require("gitlab").delete_reviewer()
require("gitlab").add_assignee()
require("gitlab").delete_assignee()

These commands use Neovim's built in picker, which is much nicer if you install dressing. If you use Dressing, please enable it:

require("dressing").setup({
    input = {
        enabled = true
    }
})

Keybindings

The plugin does not set up any keybindings outside of these buffers, you need to set them up yourself. Here's what I'm using:

local gitlab = require("gitlab")
vim.keymap.set("n", "<leader>gls", gitlab.summary)
vim.keymap.set("n", "<leader>glA", gitlab.approve)
vim.keymap.set("n", "<leader>glR", gitlab.revoke)
vim.keymap.set("n", "<leader>glr", gitlab.review)
vim.keymap.set("n", "<leader>glaa", gitlab.add_assignee)
vim.keymap.set("n", "<leader>glad", gitlab.delete_assignee)
vim.keymap.set("n", "<leader>glra", gitlab.add_reviewer)
vim.keymap.set("n", "<leader>glrd", gitlab.delete_reviewer)

Troubleshooting

To check that the current settings of the plugin are configured correctly, please run: :lua require("gitlab").print_settings()

This plugin uses a Golang server to reach out to Gitlab. It's possible that something is going wrong when starting that server or connecting with Gitlab. The Golang server runs outside of Neovim, and can be interacted with directly in order to troubleshoot. To start the server, check out your feature branch and run these commands:

:lua require("gitlab.server").build()
:lua require("gitlab.server").start()

You can directly interact with the Go server like any other process:

curl --header "PRIVATE-TOKEN: ${GITLAB_TOKEN}" localhost:21036/info

This is the API call that is happening from within Neovim when you run the summary command.

If you are able to build and start the Go server and hit the endpoint successfully for the command you are trying to run (such as creating a comment or approving a merge request) then something is wrong with the Lua code. In that case, please file a bug report.

This Go server, in turn, writes logs to the log path that is configured in your setup function. These are written by default to ~/.cache/nvim/gitlab.nvim.log and will be written each time the server reaeches out to Gitlab.

If the Golang server is not starting up correctly, please check your .gitlab.nvim file and your setup function. You can, however, try running the Golang server independently of Neovim. For instance, to start it up for a certain project, navigate to your plugin directory, and build the binary (these are instructions for Lazy) and move that binary to your project. You can then try running the binary directly, or even with a debugger like Delve:

$ cd ~/.local/share/nvim/lazy/gitlab.nvim
$ cd cmd
$ go build -gcflags=all="-N -l" -o bin && cp ./bin ~/path-to-your-project
$ cd ~/path-to-your-project
$ dlv exec ./bin -- 41057709 https://www.gitlab.com 21036 your-gitlab-token
