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.

jj.nvim brings Jujutsu (jj) to your editor. Execute jj commands directly from Neovim with rich UI integration, custom editors for commit messages, interactive diff viewing from the log, live rebasing with preview, status browsing with file restoration, and one-click PR/MR opening. It’s jj for Neovim without leaving your workflow.

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!

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.

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
• <C-n> - Create a new change after the revision under the cursor
• <S-n> - 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:

• <S-u> - Undo the last operation
• <S-r> - 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
• <S-p> - 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

Rebase changes from the log buffer

Enter an interactive rebase mode directly from the log buffer to rebase one or more changes:

• r - Enter rebase mode targeting the revision under cursor (in normal mode) or selected revisions (in visual mode)

Once in rebase mode, the interface highlights your selection and the current rebase destination:

• Selected changes are highlighted in your configured selected_hl color (default: dark magenta)
• The cursor position (potential rebase destination) is highlighted in your configured targeted_hl color (default: green)
• Move the cursor to preview different rebase destinations with live highlighting

From rebase mode, choose how to rebase:

• <CR> or o - Rebase onto (-o) the revision under cursor
• a - Rebase after (-A) the revision under cursor
• b - Rebase before (-B) the revision under cursor
• <S-CR> or <S-o> - Rebase onto (-o) ignoring immutability
• <S-a> - Rebase after (-A) ignoring immutability
• <S-b> - Rebase before (-B) ignoring immutability
• <Esc> or <C-c> - Exit rebase mode without making changes

Visual mode selection: Select multiple revisions in visual mode before pressing r to rebase them all at once. The plugin extracts each selected revision and rebases them together.

Single revision: In normal mode, place your cursor on a single revision and press r to rebase just that change.

Open a PR/MR from the log buffer

• o - Open a PR/MR for the revision under cursor
• <S-o> - 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

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.

Open a changed file

Just press enter to open the a file from the status output in your current window.

Restore a changed file

Press <S-x> on a file from the status output and that’s it, it’s restored.

Installation

Using lazy.nvim:

Using the latest stable release:

{
    "nicolasgb/jj.nvim",
    version = "*", -- Use latest stable release
    -- Or from the main branch (uncomment the branch line and comment the version line)
    -- branch = "main",
    config = function()
        require("jj").setup({})
    end,
}

Cmdline Usage

The plugin provides a :J command that accepts jj subcommands:

: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 <your-alias>

Diff Commands

The plugin also provides :Jdiff, :Jvdiff, and :Jhdiff commands for diffing against specific revisions:

: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

      },
      -- Close keymaps (shared across all buffers)
      close = { "q", "<Esc>" },
    },
  }
}

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 <Esc>, 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:

require("jj").setup({
  describe = {
    editor = {
      type = "input", -- Use simple input mode
    }
  }
})

You can also customize the keymaps for the describe editor buffer:

require("jj").setup({
  describe = {
    editor = {
      type = "buffer",
      keymaps = {
        close = { "q", "<Esc>", "<C-c>" }, -- 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:

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:

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

Configuration Examples

New Command Options

The new function accepts an options table:

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:

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:

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:

require("jj").setup({
  cmd = {
    bookmark = {
      prefix = "feature/"  -- Default prefix when creating bookmarks
    }
  }
})

The bookmark_move function moves an existing bookmark to a new revision:

local cmd = require("jj.cmd")
cmd.bookmark_move()  -- Select bookmark, then specify new revset

The bookmark_delete function deletes a bookmark:

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:

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:

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

Annotations

View file blame and line history using the annotate module. Can be invoked via command or Lua API.

Via :J command:

:J annotate         " Show blame/annotations for entire file in vertical split
:J annotate_line    " Show annotation for current line in floating buffer

Via Lua API:

local annotate = require("jj.annotate")
annotate.file()    -- Show blame/annotations for entire file in vertical split
annotate.line()    -- Show annotation for current line in a tooltip

The file annotation displays a vertical split showing:

• Change ID (colored uniquely per commit)
• Author name
• Timestamp

Press <CR> on any annotation line to view the diff for that change.

The line annotation displays a floating tooltip with the current line’s annotation and the commit description.

Example keymaps:

local annotate = require("jj.annotate")
vim.keymap.set("n", "<leader>ja", annotate.file, { desc = "JJ annotate file" })
vim.keymap.set("n", "<leader>jA", annotate.line, { desc = "JJ annotate line" })

Example config

  "nicolasgb/jj.nvim",
  dependencies = {
    "folke/snacks.nvim", -- Optional only if you use picker's
  },

  config = function()

        cursor_render_delay = 10, -- Adjust if cursor position isn't restoring correctly
      },
      cmd = {

            }
          }
        },
        bookmark = {
