Enhanced integrations

Here are some cool features you can do with jj.nvim:

View change summary from the log buffer

Quickly preview the files changed in any revision without leaving the log:

• <S-k> - Show a tooltip with the revision’s changed files
• <S-k> - To enter the tooltip buffer

From the summary view, you can:

• <S-d> - Diff the file under cursor at that revision
• <CR> - Edit the revision and open the file
• <S-CR> - Edit the revision (ignoring immutability) and open the file

Diff any change

You can diff any change in your log history by pressing <S-d> on its line or on a summary file change. This opens the configured diff backend for the revision under the cursor.

[!NOTE] Integrates with your preferred diff plugin or uses your native jj diff config. See [Diff Module]!(#diff-module).

Diff revision history

You can now open a history-aware diff between two revisions:

• In the log buffer, visually select multiple revisions and press <S-h>
• jj.nvim uses the first and last selected revisions as the range boundaries
• diffview opens DiffviewFileHistory for that range
• codediff opens CodeDiff history for that range
• The native backend currently shows a warning because history mode is not supported there yet

This is useful when you want to inspect the evolution of a stack or compare a revision range with commit history preserved instead of showing a single plain diff.

Change the log revset from the log buffer

You can change which revset the log buffer is displaying without closing and reopening it:

• <C-r> - Prompt for a new revset and reload the log buffer with it

This is useful for quickly narrowing the log to something like main::@, mutable(), or any other revset while staying in the same log view.

Describe a change

You can describe any change directly from the log buffer:

• d - Describe the revision under cursor using your configured editor

Edit changes

Jumping up and down your log history ?

In your log output press CR in a line to directly edit a mutable change. If you are sure what you are doing press S-CR (Shift Enter) to edit an 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, works in visual mode to abandon multiple changes:

• 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 a bookmark through the picker
• 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

Manage tags from the log buffer

• <S-t> - Create a new tag on the revision under cursor

Deleting and pushing tags (for colocated repositories) is also supported and changes are reflected if the log buffer is open. Set up some keybinds and you’re good to go, please see [here]!(#tag-management-command-options).

Squash changes from the log buffer

Enter an interactive squash mode to squash one or more changes into a destination:

• s - Enter squash mode targeting the revision under cursor (in normal mode) or selected revisions (in visual mode)
• <S-s> - Quick squash the revision under cursor into its parent

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

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

From squash mode, choose how to squash:

• <CR> - Squash into (-t) the revision under cursor
• <S-CR> - Squash into (-t) ignoring immutability
• <Esc> or <C-c> - Exit squash mode without making changes

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

Quick squash: In normal mode, press <S-s> to quickly squash the current revision into its parent. This ignores immutability.

Split changes from the log buffer

Split a change into two or more revisions directly from the log buffer or the command line:

• <C-s> - Split the revision under cursor from the log buffer

The split command opens an interactive floating terminal where jj guides you through selecting which changes go into the first commit. The remaining changes stay in the second commit.

[!NOTE] If you want to use something like hunk.nvim, simply follow the steps and update your jj’s config to use it as a tool and a neovim instance with hunk will be ran inside your current neovim, for a seamless integration

Other tools that ran in the terminal like jj’s native should work out of the box too.

Via :J command:

:J split              " Split @ interactively
:J split abc123       " Split a specific revision
:J split @ --parallel " Create parallel changes instead of sequential
:J split @ --message "first half" " Set a commit message for the first split

Via Lua API:

local cmd = require("jj.cmd")
cmd.split()                                      -- Split @ interactively
cmd.split({ rev = "abc123" })                    -- Split a specific revision
cmd.split({ parallel = true })                   -- Create parallel changes
cmd.split({ message = "first half" })            -- Set message for first split
cmd.split({ filesets = { "src/" } })             -- Only include specific filesets
cmd.split({ ignore_immutable = true })           -- Split an immutable revision

The floating terminal size is configurable via the split.width and split.height options (ratios between 0.1 and 1.0).

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.

Browse current file on remote

Open the current buffer’s file in your browser on the hosted remote (GitHub/GitLab/Gitea/Forgejo, etc.) at the current cursor line or a visually selected range.

Usage:

:Jbrowse          " Use @ (best-effort chooses a remote-reachable ref)
:Jbrowse main     " Use an explicit revset (no walkback)

How it works:

• Takes the current buffer path and makes it repo-relative (must be inside a jj repo)
• Collects git remotes; if there’s more than one, prompts you to pick one
• Normalizes the remote URL to an HTTPS base repo URL
• Picks a ref that is expected to exist on the remote:
  • With default @: walks back first-parent up to 20 parents to find a commit reachable from that remote’s bookmarks; falls back to trunk() if needed
  • With an explicit revset (e.g. main, @-2): uses that revset directly (no walkback)
  • If there’s a single unambiguous remote bookmark pointing at the chosen commit, uses that bookmark name; otherwise uses the commit SHA
• Builds a provider-specific URL and adds a line anchor:
  • GitHub-style: #L<start> or #L<start>-L<end>
  • GitLab-style: #L<start> or #L<start>-<end>

In Visual mode, select lines and run :Jbrowse to open a range.

Open a changed file

Just press enter to open 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.

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
      }
    }
  }
})

Editor Options

The top-level editor config controls behavior for the describe/commit editor buffers.

editor.auto_insert

When auto_insert = true, jj.nvim automatically enters Insert mode when opening a describe or commit buffer only if the description is empty.

If the change already has a description, the buffer stays in Normal mode so you can review or edit the existing message without being dropped straight into Insert mode.

Default:

require("jj").setup({
  editor = {
    auto_insert = false,
  }
})

Enable smart auto-insert:

require("jj").setup({
  editor = {
    auto_insert = true,
  }
})

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

The bookmark_track function tracks an untracked bookmark:

local cmd = require("jj.cmd")
cmd.bookmark_track()  -- Select bookmark to track

The bookmark_forget function forgets a bookmark (untracks it locally):

local cmd = require("jj.cmd")
cmd.bookmark_forget()  -- Select bookmark to forget/untrack

Tag Management Command Options

The tag_set function creates a tag on a revision:

local cmd = require("jj.cmd")
cmd.tag_set()              -- Prompts for revision and tag name
cmd.tag_set("abc123")      -- Set a tag on a specific revision (prompts for tag name)

The tag_delete function deletes a tag via picker:

local cmd = require("jj.cmd")
cmd.tag_delete()           -- Select tag to delete from picker

The tag_push function pushes a tag to a remote (colocated repositories only):

local cmd = require("jj.cmd")
cmd.tag_push()             -- Select tag to push from picker (prompts for remote if multiple)

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 Module

The diff module provides a unified API for viewing diffs with pluggable backend support.

The natively supported backends are:

• Native (Diffs the current file in place and uses a floating buffer with your jj diff command when diffing changes)
• codediff
• diffview

Functions

local diff = require("jj.diff")

-- Diff current buffer against a revision (default: @-)
-- The `layout` is only supported for the native backend
diff.diff_current({ rev = "@-", layout = "vertical" })

-- Show what changed in a single revision
diff.show_revision({ rev = "abc123" })

-- Diff between two revisions
diff.diff_revisions({ left = "main", right = "@" })

-- Open a history-aware diff between two revisions
-- Supported by the `diffview` and `codediff` backends
-- The `native` backend currently warns instead
diff.diff_history_revisions({ left = "main", right = "@" })

-- Convenience functions (LEGACY FUNCTIONS)
diff.open_vdiff()                   -- Vertical split diff against parent
diff.open_vdiff({ rev = "main" })   -- Vertical split against specific revision
diff.open_hdiff()                   -- Horizontal split diff
diff.open_hdiff({ rev = "@-2" })    -- Horizontal split against @-2

Log Buffer Integration

The diff module integrates seamlessly with the log buffer:

• <S-d> - Show diff for the revision under cursor in a floating window
• <S-h> - In visual mode, open a history-aware diff for the first and last selected revisions

These actions use the configured diff backend, allowing you to leverage your preferred diff viewer directly from the log.

Custom Diff Backends

The diff module supports pluggable backends. Built-in backends include native, diffview, and codediff. You can register your own backend:

local diff = require("jj.diff")

diff.register_backend("my-backend", {
  -- Diff current buffer against a revision
  diff_current = function(opts)
    -- opts.rev: revision to diff against (default: "@-")
    -- opts.path: file path (default: current buffer)
    -- opts.layout: "vertical" or "horizontal"
  end,

  -- Show what changed in a single revision
  show_revision = function(opts)
    -- opts.rev: revision to show
    -- opts.path: optional file filter
    -- opts.display: "floating", "tab", or "split"
  end,

  -- Diff between two revisions
  diff_revisions = function(opts)
    -- opts.left: left/base revision
    -- opts.right: right/target revision
    -- opts.path: optional file filter
    -- opts.display: "floating", "tab", or "split"
  end,

  -- Open a history-aware diff between two revisions
  diff_history_revisions = function(opts)
    -- opts.left: left/base revision
    -- opts.right: right/target revision
  end,
})

Set your backend as default in the config:

require("jj").setup({
  diff = {
    backend = "my-backend"
  }
})

Or use it per-call:

diff.diff_current({ backend = "my-backend", rev = "main" })

All four backend functions are optional—missing ones fall back to the native implementation.

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 needed if you use pickers

    -- One of these two if you want to use them as your diff backend
    "esmuellert/codediff.nvim",
    "sindrets/diffview.nvim",
  },

  config = function()
    local jj = require("jj")
    jj.setup({
      terminal = {
        cursor_render_delay = 10, -- Adjust if cursor position isn't restoring correctly
      },
      diff = {
          backend = "codediff"
      },
      cmd = {
        describe = {
          editor = {
            type = "buffer",
            keymaps = {
              close = { "q", "<Esc>", "<C-c>" }, -- Enable <Esc> in the editor
            }
          }
        },
        bookmark = {
            prefix = "feat/"
        },
        keymaps = {
          log = {
            edit = "<CR>",
            describe = "d",
            diff = "<S-d>",
            abandon = "<S-a>",
            fetch = "<S-f>",
          },
          status = {
            open_file = "<CR>",
            restore_file = "<S-x>",
          },
          close = { "q", "<Esc>" },
        },
      },
      highlights = {
        editor = {
          -- Customize colors if desired
          modified = { fg = "#89ddff" },
        }
      }
