## Installation
|
|
|
|
With <a href="https://github.com/folke/lazy.nvim">Lazy</a>:
|
|
|
|
```lua
|
|
return {
|
|
"harrisoncramer/gitlab.nvim",
|
|
dependencies = {
|
|
"MunifTanjim/nui.nvim",
|
|
"nvim-lua/plenary.nvim"
|
|
},
|
|
build = function () require("gitlab").build() end, -- Builds the Go binary
|
|
config = function()
|
|
require("gitlab").setup()
|
|
end,
|
|
}
|
|
```
|
|
|
|
And with Packer:
|
|
|
|
```lua
|
|
use {
|
|
'harrisoncramer/gitlab.nvim',
|
|
requires = {
|
|
"MunifTanjim/nui.nvim",
|
|
"nvim-lua/plenary.nvim"
|
|
},
|
|
run = function() require("gitlab").build() end,
|
|
config = function()
|
|
require("gitlab").setup()
|
|
end,
|
|
}
|
|
```
|
|
|
|
## Configuration
|
|
|
|
This plugin requires a `.gitlab.nvim` file in the root of the local Gitlab directory. Provide this file with values required to connect to your gitlab instance (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:
|
|
|
|
```bash
|
|
export AUTH_TOKEN="your_gitlab_token"
|
|
```
|
|
|
|
By default, the plugin will interact with MRs against a "main" branch. You can configure this by passing in the `base_branch` option to the `.gitlab.nvim` configuration file for your project.
|
|
|
|
```
|
|
project_id=112415
|
|
auth_token=your_gitlab_token
|
|
gitlab_url=https://my-personal-gitlab-instance.com
|
|
base_branch=master
|
|
```
|
|
|
|
## 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:
|
|
|
|
```lua
|
|
require("gitlab").setup({
|
|
port = 20136, -- 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
|
|
keymaps = {
|
|
popup = { -- The popup for comment creation, editing, and replying
|
|
exit = "<Esc>",
|
|
perform_action = "<leader>s", -- Once in normal mode, does action
|
|
},
|
|
discussion_tree = { -- The discussion tree that holds all comments
|
|
jump_to_location = "o",
|
|
edit_comment = "e",
|
|
delete_comment = "dd",
|
|
reply_to_comment = "r",
|
|
toggle_node = "t",
|
|
position = "left", -- "top", "right", "bottom" or "left"
|
|
size = "20%", -- Size of split
|
|
relative = "editor" -- Position relative to "editor" or "window"
|
|
},
|
|
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 and the reviewer will be initialized. 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:
|
|
|
|
```lua
|
|
require("gitlab").summary()
|
|
```
|
|
|
|
The `approve` command will approve the merge request for the current branch:
|
|
|
|
```lua
|
|
require("gitlab").approve()
|
|
```
|
|
|
|
The `revoke` command will revoke approval for the merge request for the current branch:
|
|
|
|
```lua
|
|
require("gitlab").revoke()
|
|
```
|
|
|
|
The `comment` command will open up a NUI popover that will allow you to create a Gitlab comment on the current line. To send the comment, use `<leader>s` while the comment popup is open:
|
|
|
|
```lua
|
|
require("gitlab").comment()
|
|
```
|
|
|
|
### Discussions
|
|
|
|
Gitlab groups threads of notes together into "disucssions." To get a list of all the discussions for the current MR, use the `list_discussions` command. This command will open up a split view of all the comments on the current merge request. You can jump to the comment location by using the `o` key in the tree buffer, and you can reply to a thread by using the `r` keybinding in the tree buffer:
|
|
|
|
```lua
|
|
require("gitlab").list_discussions()
|
|
```
|
|
|
|
Within the discussion tree, there are several functions that you can call, however, it's better to use the keybindings provided in the setup function. If you want to call them manually, they are:
|
|
|
|
```lua
|
|
require("gitlab").delete_comment()
|
|
require("gitlab").edit_comment()
|
|
require("gitlab").reply()
|
|
```
|
|
|
|
## 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:
|
|
|
|
```lua
|
|
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>glc", gitlab.create_comment)
|
|
vim.keymap.set("n", "<leader>gld", gitlab.list_discussions)
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
This plugin uses a Golang server to reach out to Gitlab. The Golang server runs outside of Neovim, and can be interacted with directly in order to troubleshoot. The server will start up when you open Neovim with a MR branch. You can curl it directly:
|
|
|
|
```
|
|
curl --header "PRIVATE-TOKEN: ${GITLAB_TOKEN}" localhost:21036/info
|
|
```
|
|
|
|
This is the API call that is happening from within Neovim when you run the `:lua require("gitlab").summary()` command.
|
|
|
|
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:
|
|
|
|
```bash
|
|
$ 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
|
|
```
