# jj.nvim ⚠️ **WORK IN PROGRESS** ⚠️ > **Note:** This project is pre-v1. Breaking changes may occur in the configuration, API, and features until v1.0.0 is released. A Neovim plugin for [Jujutsu (jj)](https://github.com/jj-vcs/jj) version control system. ## About This plugin aims to be something like vim-fugitive but for driving the jj-vcs CLI. The goal is to eventually provide features similar to git status, diffs, and pickers for managing Jujutsu repositories directly from Neovim. ![Demo](https://github.com/NicolasGB/jj.nvim/raw/main/assets/demo.gif) ## Current Features - Basic jj command execution through `:J` command - Terminal-based output display for jj commands - Support jj subcommands including your aliases through the cmdline. - First class citizens with ui integration - `describe` / `desc` - Set change descriptions with a Git-style commit message editor - `status` / `st` - Show repository status - `log` - Display log history with configurable options - `diff` - Show changes with optional filtering by current file - `new` - Create a new change with optional parent selection - `edit` - Edit a change - `squash` - Squash the current diff to it's parent - `rebase` - Rebase changes to a destination - `bookmark create/delete` - Create and delete bookmarks - `undo` - Undo the last operation - `redo` - Redo the last undone operation - `open_pr` - Open a PR/MR on your remote (GitHub, GitLab, Gitea, Forgejo, etc.) - Diff commands - `:Jdiff [revision]` - Vertical split diff against a jj revision - `:Jhdiff [revision]` - Horizontal split diff - Picker for for [Snacks.nvim](https://github.com/folke/snacks.nvim) - `jj status` Displays the current changes diffs - `jj file_history` Displays a buffer's history changes and allows to edit it's change (including immutable changes) ## Enhanced integrations Here are some cool features you can do with jj.nvim: ### Diff any change You can diff any change in your log history by simply pressing `d` on its line, yeah just like that! ![Diff-from-log](https://github.com/NicolasGB/jj.nvim/raw/main/assets/diff-log.gif) ### Edit changes Jumping up and down your log history ? In your log ouptut press `CR` in a line to directly edit a `mutable` change. If you are sure what your are doing press `S-CR` (Shift Enter) to edit a `immutable` change. ![Edit-from-log](https://github.com/NicolasGB/jj.nvim/raw/main/assets/edit-log.gif) ### Create new changes from the log buffer You can create new changes directly from the log buffer with multiple options: - `n` - Create a new change branching off the revision under the cursor - `` - Create a new change after the revision under the cursor - `` - Create a new change after while ignoring immutability constraints ### Undo/Redo from the log buffer You can undo/redo changes directly from the log buffer: - `` - Undo the last operation - `` - Redo the last undone operation ### Abandon changes from the log buffer You can abandon changes directly from the log buffer: - `a` - Abandon the revision under the cursor ### Fetch and push from the log buffer You can fetch and push directly from the log buffer: - `f` - Fetch from remote - `` - Push all changes to remote - `p` - Push bookmark of revision under cursor to remote ### Manage bookmarks from the log buffer - `b` - Create a new bookmark or move an existing one to the revision under cursor - Select from existing bookmarks to move them - Or create a new bookmark at that revision ### Open a PR/MR from the log buffer - `o` - Open a PR/MR for the revision under cursor - `` - Select a remote from all available bookmarks and open a PR/MR The plugin automatically: - Extracts the bookmark from the revision - Detects your git platform (GitHub, GitLab, Gitea, Forgejo, etc.) - Constructs the appropriate PR/MR URL - Handles both HTTPS and SSH remote URLs - Prompts you to select a remote if you have multiple ### Open a changed file Just press enter to open the a file from the `status` output in your current window. ![Open-status](https://github.com/NicolasGB/jj.nvim/raw/main/assets/enter-status.gif) ### Restore a changed file Press `` on a file from the `status` output and that's it, it's restored. ![Restore-status](https://github.com/NicolasGB/jj.nvim/raw/main/assets/x-status.gif) ### Open a PR/MR on your remote Press `o` on a change in the log buffer to open a PR/MR on your remote (GitHub, GitLab, Gitea, Forgejo, etc.). The plugin automatically detects your git platform and constructs the appropriate PR URL. If you have multiple remotes, you'll be prompted to select which one to use. Works with both HTTPS and SSH URLs. **This is a jj.nvim exclusive feature** - the ability to seamlessly bridge from your Neovim jj workflow directly to your remote platform's PR/MR interface. ## Installation Using [lazy.nvim](https://github.com/folke/lazy.nvim): ```lua { "nicolasgb/jj.nvim", config = function() require("jj").setup({}) end, } ``` ## Cmdline Usage The plugin provides a `:J` command that accepts jj subcommands: ```sh :J status :J log :J describe "Your change description" :J new :J push " Push all changes :J push main " Push only main bookmark :J fetch " Fetch from remote :J open_pr " Open PR for current change's bookmark :J open_pr --list " Select bookmark from all and open PR :J bookmark create/move/delete :J # This will use your defined default command :J ``` ### Diff Commands The plugin also provides `:Jdiff`, `:Jvdiff`, and `:Jhdiff` commands for diffing against specific revisions: ```sh :Jdiff " Vertical diff against @- (parent) :Jdiff @-2 " Vertical diff against specific revision :Jvdiff main " Vertical diff against main bookmark :Jhdiff trunk() " Horizontal diff against trunk ``` ## Default Config ```lua { -- Setup snacks as a picker picker = { -- Here you can pass the options as you would for snacks. -- It will be used when using the picker snacks = {} }, -- Customize syntax highlighting colors for the describe buffer highlights = { added = { fg = "#3fb950", ctermfg = "Green" }, -- Added files modified = { fg = "#56d4dd", ctermfg = "Cyan" }, -- Modified files deleted = { fg = "#f85149", ctermfg = "Red" }, -- Deleted files renamed = { fg = "#d29922", ctermfg = "Yellow" }, -- Renamed files }, -- Configure terminal behavior terminal = { -- Cursor render delay in milliseconds (default: 10) -- If cursor column is being reset to 0 when refreshing commands, try increasing this value -- This delay allows the terminal emulator to complete rendering before restoring cursor position cursor_render_delay = 10, }, -- Configure cmd module (describe editor, keymaps) cmd = { -- Configure describe editor describe = { editor = { -- Choose the editor mode for describe command -- "buffer" - Opens a Git-style commit message buffer with syntax highlighting (default) -- "input" - Uses a simple vim.ui.input prompt type = "buffer", -- Customize keymaps for the describe editor buffer keymaps = { close = { "", "", "q" }, -- Keys to close editor without saving } } }, -- Configure log command behavior log = { close_on_edit = false, -- Close log buffer after editing a change }, -- Configure bookmark command bookmark = { prefix = "" }, -- Configure keymaps for command buffers keymaps = { -- Log buffer keymaps (set to nil to disable) log = { checkout = "", -- Edit revision under cursor checkout_immutable = "", -- Edit revision (ignore immutability) describe = "d", -- Describe revision under cursor diff = "", -- Diff revision under cursor edit = "e", -- Edit revision under cursor new = "n", -- Create new change branching off new_after = "", -- Create new change after revision new_after_immutable = "", -- Create new change after (ignore immutability) undo = "", -- Undo last operation redo = "", -- Redo last undone operation abandon = "a", -- Abandon revision under cursor bookmark = "b", -- Create or move bookmark to revision under cursor fetch = "f", -- Fetch from remote push = "p", -- Push bookmark of revision under cursor push_all = "", -- Push all changes to remote open_pr = "o", -- Open PR/MR for revision under cursor open_pr_list = "", -- Open PR/MR by selecting from all bookmarks }, -- Status buffer keymaps (set to nil to disable) status = { open_file = "", -- Open file under cursor restore_file = "", -- Restore file under cursor }, -- Close keymaps (shared across all buffers) close = { "q", "" }, }, } } ``` ### Describe Editor Modes The `describe.editor.type` option lets you choose how you want to write commit descriptions: - **`"buffer"`** (default) - Opens a full buffer editor similar to Git's commit message editor - Shows file changes with syntax highlighting - Multi-line editing with proper formatting - Close with `q` or ``, save with `:w` or `:wq` - **`"input"`** - Simple single-line input prompt - Quick and minimal - Good for short, single-line descriptions - Uses `vim.ui.input()` which can be customized by UI plugins like dressing.nvim Example: ```lua require("jj").setup({ describe = { editor = { type = "input", -- Use simple input mode } } }) ``` You can also customize the keymaps for the describe editor buffer: ```lua require("jj").setup({ describe = { editor = { type = "buffer", keymaps = { close = { "q", "", "" }, -- Customize close keybindings } } } }) ``` ### Highlight Customization The `highlights` option allows you to customize the colors used in the describe buffer's file status display. Each highlight accepts standard Neovim highlight attributes: - `fg` - Foreground color (hex or color name) - `bg` - Background color - `ctermfg` - Terminal foreground color - `ctermbg` - Terminal background color - `bold`, `italic`, `underline` - Text styles Example with custom colors: ```lua require("jj").setup({ highlights = { modified = { fg = "#89ddff", bold = true }, added = { fg = "#c3e88d", ctermfg = "LightGreen" }, } }) ``` ## Lua API Usage Beyond the `:J` command, you can call functions directly from Lua for more control. The example config below shows how to use them with custom keymaps. ### Log Command Options The `log` function accepts an options table: ```lua local cmd = require("jj.cmd") cmd.log({ summary = false, -- Show summary of changes (default: false) reversed = false, -- Reverse the log order (default: false) no_graph = false, -- Hide the graph (default: false) limit = 20, -- Limit number of entries (default: 20) revisions = "'all()'" -- Revision specifier (default: all reachable) }) -- Examples: cmd.log({ limit = 50 }) -- Show 50 entries cmd.log({ revisions = "'main::@'" }) -- Show commits between main and current cmd.log({ summary = true, limit = 100 }) -- Show summary with high limit cmd.log({ raw = "-r 'main::@' --summary --no-graph" }) -- Pass raw flags directly ``` ### New Command Options The `new` function accepts an options table: ```lua local cmd = require("jj.cmd") cmd.new({ show_log = false, -- Display log after creating new change (default: false) with_input = false, -- Prompt for parent revision (default: false) args = "" -- Additional arguments to pass to jj new }) -- Examples: cmd.new({ show_log = true }) -- Create new and show log cmd.new({ show_log = true, with_input = true }) -- Prompt for parent cmd.new({ args = "--before @" }) -- Pass custom args ``` ### Push Command Options The `push` function accepts an options table: ```lua local cmd = require("jj.cmd") cmd.push({ bookmark = "main" -- Push specific bookmark (default: all changes) }) -- Examples: cmd.push() -- Push all changes cmd.push({ bookmark = "main" }) -- Push only main bookmark cmd.push({ bookmark = "feature" }) -- Push only feature bookmark ``` ### Bookmark Management Command Options The `bookmark_create` function creates a new bookmark: ```lua local cmd = require("jj.cmd") cmd.bookmark_create() -- Prompts for bookmark name, then prompts the revision cmd.bookmark_create({ prefix = "feature/" }) -- Uses prefix for default bookmark name ``` You can also set a default bookmark prefix in the config: ```lua require("jj").setup({ cmd = { bookmark = { prefix = "feature/" -- Default prefix when creating bookmarks } } }) ``` The `bookmark_move` function moves an existing bookmark to a new revision: ```lua local cmd = require("jj.cmd") cmd.bookmark_move() -- Select bookmark, then specify new revset ``` The `bookmark_delete` function deletes a bookmark: ```lua local cmd = require("jj.cmd") cmd.bookmark_delete() -- Select bookmark to delete ``` ### Open PR/MR Command Options The `open_pr` function accepts an options table: ```lua local cmd = require("jj.cmd") cmd.open_pr({ list_bookmarks = false -- Whether to select from all bookmarks (default: false, uses current revision) }) -- Examples: cmd.open_pr() -- Open PR for current change's bookmark cmd.open_pr({ list_bookmarks = true }) -- Select bookmark from all and open PR ``` ### Diff Split Views Use the `diff` module for opening splits: ```lua local diff = require("jj.diff") diff.open_diff() -- Vertical split diff against parent diff.open_diff({ rev = "main" }) -- Vertical split against specific revision diff.open_hsplit() -- Horizontal split diff diff.open_hsplit({ rev = "@-2" }) -- Horizontal split against @-2 ``` ## Example config ```lua { "nicolasgb/jj.nvim", dependencies = { "folke/snacks.nvim", -- Optional only if you use picker's }, config = function() local jj = require("jj") jj.setup({ terminal = { cursor_render_delay = 10, -- Adjust if cursor position isn't restoring correctly }, cmd = { describe = { editor = { type = "buffer", keymaps = { close = { "q", "", "" }, } } }, bookmark = { prefix = "feat/" }, keymaps = { log = { checkout = "", describe = "d", diff = "", abandon = "", fetch = "", }, status = { open_file = "", restore_file = "", }, close = { "q", "" }, }, }, highlights = { -- Customize colors if desired modified = { fg = "#89ddff" }, } }) -- Core commands local cmd = require("jj.cmd") vim.keymap.set("n", "jd", cmd.describe, { desc = "JJ describe" }) vim.keymap.set("n", "jl", cmd.log, { desc = "JJ log" }) vim.keymap.set("n", "je", cmd.edit, { desc = "JJ edit" }) vim.keymap.set("n", "jn", cmd.new, { desc = "JJ new" }) vim.keymap.set("n", "js", cmd.status, { desc = "JJ status" }) vim.keymap.set("n", "sj", cmd.squash, { desc = "JJ squash" }) vim.keymap.set("n", "ju", cmd.undo, { desc = "JJ undo" }) vim.keymap.set("n", "jy", cmd.redo, { desc = "JJ redo" }) vim.keymap.set("n", "jr", cmd.rebase, { desc = "JJ rebase" }) vim.keymap.set("n", "jbc", cmd.bookmark_create, { desc = "JJ bookmark create" }) vim.keymap.set("n", "jbd", cmd.bookmark_delete, { desc = "JJ bookmark delete" }) vim.keymap.set("n", "jbm", cmd.bookmark_move, { desc = "JJ bookmark move" }) vim.keymap.set("n", "ja", cmd.abandon, { desc = "JJ abandon" }) vim.keymap.set("n", "jf", cmd.fetch, { desc = "JJ fetch" }) vim.keymap.set("n", "jp", cmd.push, { desc = "JJ push" }) vim.keymap.set("n", "jpr", cmd.open_pr, { desc = "JJ open PR from bookmark in current revision or parent" }) vim.keymap.set("n", "jpl", function() cmd.open_pr { list_bookmarks = true } end, { desc = "JJ open PR listing available bookmarks" }) -- Diff commands local diff = require("jj.diff") vim.keymap.set("n", "df", function() diff.open_vdiff() end, { desc = "JJ diff current buffer" }) vim.keymap.set("n", "dF", function() diff.open_hsplit() end, { desc = "JJ hdiff current buffer" }) -- Pickers local picker = require("jj.picker") vim.keymap.set("n", "gj", function() picker.status() end, { desc = "JJ Picker status" }) vim.keymap.set("n", "jgh", function() picker.file_history() end, { desc = "JJ Picker history" }) -- Some functions like `log` can take parameters vim.keymap.set("n", "jL", function() cmd.log { revisions = "'all()'", -- equivalent to jj log -r :: } end, { desc = "JJ log all" }) -- This is an alias i use for moving bookmarks its so good vim.keymap.set("n", "jt", function() cmd.j "tug" cmd.log {} end, { desc = "JJ tug" }) end, } ``` ## Requirements - [Jujutsu](https://github.com/jj-vcs/jj) installed and available in PATH ## Contributing This is an early-stage project. Contributions are welcome, but please be aware that the API and features are likely to change significantly. ## Documentation Once the plugin is more complete i'll write docs for each of the commands. ## FAQ - Telescope Suport? Planned but i don't use it, it's already thought of by design, will implement it at some point or if someone submits a PR i'll accept it gladly. ## License [MIT](License)
