  • untrack — Stop tracking specified paths in the working copy
  • version — Display version information
  • workspace — Commands for working with workspaces
Options:

  • -R, --repository <REPOSITORY> — Path to repository to operate on

    By default, Jujutsu searches for the closest .jj/ directory in an ancestor of the current working directory.

  • --ignore-working-copy — Don't snapshot the working copy, and don't update it

    By default, Jujutsu snapshots the working copy at the beginning of every command. The working copy is also updated at the end of the command, if the command modified the working-copy commit (@). If you want to avoid snapshotting the working copy and instead see a possibly stale working copy commit, you can use --ignore-working-copy. This may be useful e.g. in a command prompt, especially if you have another process that commits the working copy.

    Loading the repository at a specific operation with --at-operation implies --ignore-working-copy.

  • --ignore-immutable — Allow rewriting immutable commits

    By default, Jujutsu prevents rewriting commits in the configured set of immutable commits. This option disables that check and lets you rewrite any commit but the root commit.

    This option only affects the check. It does not affect the immutable_heads() revset or the immutable template keyword.

  • --at-operation <AT_OPERATION> — Operation to load the repo at

    Operation to load the repo at. By default, Jujutsu loads the repo at the most recent operation. You can use --at-op=<operation ID> to see what the repo looked like at an earlier operation. For example jj --at-op=<operation ID> st will show you what jj st would have shown you when the given operation had just finished.

    Use jj op log to find the operation ID you want. Any unambiguous prefix of the operation ID is enough.

    When loading the repo at an earlier operation, the working copy will be ignored, as if --ignore-working-copy had been specified.

    It is possible to run mutating commands when loading the repo at an earlier operation. Doing that is equivalent to having run concurrent commands starting at the earlier operation. There's rarely a reason to do that, but it is possible.

    Default value: @

  • --debug — Enable debug logging

  • --color <WHEN> — When to colorize output (always, never, debug, auto)

  • --quiet — Silence non-primary command output

    For example, jj file list will still list files, but it won't tell you if the working copy was snapshotted or if descendants were rebased.

    Warnings and errors will still be printed.

  • --no-pager — Disable the pager

  • --config-toml <TOML> — Additional configuration options (can be repeated)

jj abandon

Abandon a revision

Abandon a revision, rebasing descendants onto its parent(s). The behavior is similar to jj restore --changes-in; the difference is that jj abandon gives you a new change, while jj restore updates the existing change.

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj abandon [OPTIONS] [REVISIONS]...

  • <REVISIONS> — The revision(s) to abandon

    Default value: @

Options:
  • -s, --summary — Do not print every abandoned commit on a separate line

Arguments:

  • <BRANCH@REMOTE> — Remote branches to track

    By default, the specified name matches exactly. Use glob: prefix to select branches by wildcard pattern. For details, see https://github.com/martinvonz/jj/blob/main/docs/revsets.md#string-patterns.

    Examples: branch@remote, glob:main@, glob:jjfan-@upstream

jj branch untrack

Stop tracking given remote branches

    You can use it in combination with the JJ_USER and JJ_EMAIL environment variables to set a different author:

    $ JJ_USER='Foo Bar' JJ_EMAIL=foo@bar.com jj describe --reset-author

jj diff

Compare file contents between two revisions

With the -r option, which is the default, shows the changes compared to the parent revision. If there are several parent revisions (i.e., the given revision is a merge), then they will be merged and the changes from the result to the given revision will be shown.

With the --from and/or --to options, shows the difference from/to the given revisions. If either is left out, it defaults to the working-copy commit. For example, jj diff --from main shows the changes from "main" (perhaps a branch name) to the working-copy commit.

Usage: jj diff [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Restrict the diff to these paths
Options:

  • -r, --revision <REVISION> — Show changes in this revision, compared to its parent(s)

    If the revision is a merge commit, this shows changes from the automatic merge of the contents of all of its parents to the contents of the revision itself.

  • --from <FROM> — Show changes from this revision

  • --to <TO> — Show changes to this revision
  • -s, --summary — For each path, show only whether it was modified, added, or deleted
  • --stat — Show a histogram of the changes

  • --types — For each path, show only its type before and after

    The diff is shown as two letters. The first letter indicates the type before and the second letter indicates the type after. '-' indicates that the path was not present, 'F' represents a regular file, `L' represents a symlink, 'C' represents a conflict, and 'G' represents a Git submodule.

  • --name-only — For each path, show only its path

    Typically useful for shell commands like: jj diff -r @- --name_only | xargs perl -pi -e's/OLD/NEW/g

  • --git — Show a Git-format diff

  • --color-words — Show a word-level diff with changes indicated only by color
  • --tool <TOOL> — Generate diff by external command
  • --context <CONTEXT> — Number of lines of context to show

jj diffedit

Touch up the content changes in a revision with a diff editor

With the -r option, which is the default, starts a diff editor on the changes in the revision.

With the --from and/or --to options, starts a diff editor comparing the "from" revision to the "to" revision.

Edit the right side of the diff until it looks the way you want. Once you close the editor, the revision specified with -r or --to will be updated. Descendants will be rebased on top as usual, which may result in conflicts.

See jj restore if you want to move entire files from one revision to another. See jj squash -i or jj unsquash -i if you instead want to move changes into or out of the parent revision.

Usage: jj diffedit [OPTIONS]

Options:
  • -r, --revision <REVISION> — The revision to touch up. Defaults to @ if neither --to nor --from are specified
  • --from <FROM> — Show changes from this revision. Defaults to @ if --to is specified
  • --to <TO> — Edit changes in this revision. Defaults to @ if --from is specified
  • --tool <NAME> — Specify diff editor to be used

jj duplicate

Create a new change with the same content as an existing one

Usage: jj duplicate [REVISIONS]...

Arguments:

  • <REVISIONS> — The revision(s) to duplicate

    Default value: @

jj edit

Sets the specified revision as the working-copy revision

Note: it is generally recommended to instead use jj new and jj squash.

For more information, see https://martinvonz.github.io/jj/latest/FAQ#how-do-i-resume-working-on-an-existing-change

Usage: jj edit <REVISION>

Arguments:
  • <REVISION> — The commit to edit

jj file

File operations

Usage: jj file <COMMAND>

Subcommands:
  • chmod — Sets or removes the executable bit for paths in the repo
  • list — List files in a revision
  • show — Print contents of files in a revision

jj file chmod

Sets or removes the executable bit for paths in the repo

Unlike the POSIX chmod, jj file chmod also works on Windows, on conflicted files, and on arbitrary revisions.

Usage: jj file chmod [OPTIONS] <MODE> <PATHS>...

Arguments:

  • <MODE>

    Possible values:

    • n: Make a path non-executable (alias: normal)
    • x: Make a path executable (alias: executable)

  • <PATHS> — Paths to change the executable bit for

Options:

  • -r, --revision <REVISION> — The revision to update

    Default value: @

jj file list

List files in a revision

Usage: jj file list [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Only list files matching these prefixes (instead of all files)
Options:

  • -r, --revision <REVISION> — The revision to list files in

    Default value: @

jj file show

Usage: jj file show [OPTIONS] <PATHS>...

Arguments:
  • <PATHS> — Paths to print
Options:

  • -r, --revision <REVISION> — The revision to get the file contents from

    Default value: @

jj fix

Update files with formatting fixes or other changes

The primary use case for this command is to apply the results of automatic code formatting tools to revisions that may not be properly formatted yet. It can also be used to modify files with other tools like sed or sort.

The changed files in the given revisions will be updated with any fixes determined by passing their file content through any external tools the user has configured for those files. Descendants will also be updated by passing their versions of the same files through the same tools, which will ensure that the fixes are not lost. This will never result in new conflicts. Files with existing conflicts will be updated on all sides of the conflict, which can potentially increase or decrease the number of conflict markers.

The external tools must accept the current file content on standard input, and return the updated file content on standard output. A tool's output will not be used unless it exits with a successful exit code. Output on standard error will be passed through to the terminal.

Tools are defined in a table where the keys are arbitrary identifiers and the values have the following properties:

  • command: The arguments used to run the tool. The first argument is the path to an executable file. Arguments can contain the substring $path, which will be replaced with the repo-relative path of the file being fixed. It is useful to provide the path to tools that include the path in error messages, or behave differently based on the directory or file name.
  • patterns: Determines which files the tool will affect. If this list is empty, no files will be affected by the tool. If there are multiple patterns, the tool is applied only once to each file in the union of the patterns.

For example, the following configuration defines how two code formatters (clang-format and black) will apply to three different file extensions (.cc, .h, and .py):

[fix.tools.clang-format] command = ["/usr/bin/clang-format", "--assume-filename=$path"] patterns = ["glob:'/*.cc'", "glob:'/*.h'"]

[fix.tools.black] command = ["/usr/bin/black", "-", "--stdin-filename=$path"] patterns = ["glob:'*/.py'"]

Execution order of tools that affect the same file is deterministic, but currently unspecified, and may change between releases. If two tools affect the same file, the second tool to run will receive its input from the output of the first tool.

There is also a deprecated configuration schema that defines a single command that will affect all changed files in the specified revisions. For example, the following configuration would apply the Rust formatter to all changed files (whether they are Rust files or not):

[fix] tool-command = ["rustfmt", "--emit", "stdout"]

The tool defined by tool-command acts as if it was the first entry in fix.tools, and uses pattern = "all()"``. Support fortool-command` will be removed in a future version.

Usage: jj fix [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Fix only these paths
Options:
  • -s, --source <SOURCE> — Fix files in the specified revision(s) and their descendants. If no revisions are specified, this defaults to the revsets.fix setting, or reachable(@, mutable()) if it is not set

jj git

Commands for working with Git remotes and the underlying Git repo

For a comparison with Git, including a table of commands, see https://github.com/martinvonz/jj/blob/main/docs/git-comparison.md.

Usage: jj git <COMMAND>

Subcommands:
  • clone — Create a new repo backed by a clone of a Git repo
  • export — Update the underlying Git repo with changes made in the repo
  • fetch — Fetch from a Git remote
  • import — Update repo with changes made in the underlying Git repo
  • init — Create a new Git backed repo
  • push — Push to a Git remote
  • remote — Manage Git remotes

jj git clone

Create a new repo backed by a clone of a Git repo

The Git repo will be a bare git repo stored inside the .jj/ directory.

Usage: jj git clone [OPTIONS] <SOURCE> [DESTINATION]

Arguments:
  • <SOURCE> — URL or path of the Git repo to clone
  • <DESTINATION> — Specifies the target directory for the Jujutsu repository clone. If not provided, defaults to a directory named after the last component of the source URL. The full directory path will be created if it doesn't exist
Options:
  • --colocate — Whether or not to colocate the Jujutsu repo with the git repo

jj git export

Update the underlying Git repo with changes made in the repo

Usage: jj git export

jj git fetch

Fetch from a Git remote

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj git fetch [OPTIONS]

Options:

  • -b, --branch <BRANCH> — Fetch only some of the branches

    By default, the specified name matches exactly. Use glob: prefix to expand * as a glob. The other wildcard characters aren't supported.

    Default value: glob:*

  • --remote <remote> — The remote to fetch from (only named remotes are supported, can be repeated)

  • --all-remotes — Fetch from all remotes

jj git import

Update repo with changes made in the underlying Git repo

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj git import

jj git init

Create a new Git backed repo

Usage: jj git init [OPTIONS] [DESTINATION]

Arguments:

  • <DESTINATION> — The destination directory where the jj repo will be created. If the directory does not exist, it will be created. If no directory is given, the current directory is used.

    By default the git repo is under $destination/.jj

    Default value: .

Options:

  • --colocate — Specifies that the jj repo should also be a valid git repo, allowing the use of both jj and git commands in the same directory.

    This is done by placing the backing git repo into a .git directory in the root of the jj repo along with the .jj directory. If the .git directory already exists, all the existing commits will be imported.

    This option is mutually exclusive with --git-repo.

  • --git-repo <GIT_REPO> — Specifies a path to an existing git repository to be used as the backing git repo for the newly created jj repo.

    If the specified --git-repo path happens to be the same as the jj repo path (both .jj and .git directories are in the same working directory), then both jj and git commands will work on the same repo. This is called a co-located repo.

    This option is mutually exclusive with --colocate.

jj git push

Push to a Git remote

By default, pushes any branches pointing to remote_branches(remote=<remote>)..@. Use --branch to push specific branches. Use --all to push all branches. Use --change to generate branch names based on the change IDs of specific commits.

Before the command actually moves, creates, or deletes a remote branch, it makes several safety checks. If there is a problem, you may need to run jj git fetch --remote <remote name> and/or resolve some branch conflicts.

Usage: jj git push [OPTIONS]

Options:
  • --remote <REMOTE> — The remote to push to (only named remotes are supported)

  • -b, --branch <BRANCH> — Push only this branch, or branches matching a pattern (can be repeated)

    By default, the specified name matches exactly. Use glob: prefix to select branches by wildcard pattern. For details, see https://martinvonz.github.io/jj/latest/revsets#string-patterns.

  • --all — Push all branches (including deleted branches)

  • --tracked — Push all tracked branches (including deleted branches)

    This usually means that the branch was already pushed to or fetched from the relevant remote. For details, see https://martinvonz.github.io/jj/latest/branches#remotes-and-tracked-branches

  • --deleted — Push all deleted branches

    Only tracked branches can be successfully deleted on the remote. A warning will be printed if any untracked branches on the remote correspond to missing local branches.

  • --allow-empty-description — Allow pushing commits with empty descriptions

  • --allow-private — Allow pushing commits that are private
  • -r, --revisions <REVISIONS> — Push branches pointing to these commits (can be repeated)
  • -c, --change <CHANGE> — Push this commit by creating a branch based on its change ID (can be repeated)
  • --dry-run — Only display what will change on the remote

Usage: jj init [DESTINATION]

Arguments:

  • <DESTINATION> — The destination directory

    Default value: .

jj interdiff

Compare the changes of two commits

This excludes changes from other commits by temporarily rebasing --from onto --to's parents. If you wish to compare the same change across versions, consider jj obslog -p instead.

jj log

Show revision history

Renders a graphical view of the project's history, ordered with children before parents. By default, the output only includes mutable revisions, along with some additional revisions for context.

Spans of revisions that are not included in the graph per --revisions are rendered as a synthetic node labeled "(elided revisions)".

Usage: jj log [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Show revisions modifying the given paths
Options:
  • -r, --revisions <REVISIONS> — Which revisions to show. If no paths nor revisions are specified, this defaults to the revsets.log setting, or @ | ancestors(immutable_heads().., 2) | trunk() if it is not set
  • --reversed — Show revisions in the opposite order (older revisions first)

  • -n, --limit <LIMIT> — Limit number of revisions to show

    Applied after revisions are filtered and reordered.

  • --stat — Show a histogram of the changes

  • --types — For each path, show only its type before and after

    The diff is shown as two letters. The first letter indicates the type before and the second letter indicates the type after. '-' indicates that the path was not present, 'F' represents a regular file, `L' represents a symlink, 'C' represents a conflict, and 'G' represents a Git submodule.

  • --name-only — For each path, show only its path

    Typically useful for shell commands like: jj diff -r @- --name_only | xargs perl -pi -e's/OLD/NEW/g

  • --git — Show a Git-format diff

  • --color-words — Show a word-level diff with changes indicated only by color
  • --tool <TOOL> — Generate diff by external command
  • --context <CONTEXT> — Number of lines of context to show

jj new

Create a new, empty change and (by default) edit it in the working copy

By default, jj will edit the new change, making the working copy represent the new commit. This can be avoided with --no-edit.

Note that you can create a merge commit by specifying multiple revisions as argument. For example, jj new main @ will create a new commit with the main branch and the working copy as parents.

For more information, see https://github.com/martinvonz/jj/blob/main/docs/working-copy.md.

Usage: jj new [OPTIONS] [REVISIONS]...

Arguments:

  • <REVISIONS> — Parent(s) of the new change

    Default value: @

Options:
  • -m, --message <MESSAGE> — The change description to use
  • --no-edit — Do not edit the newly created change
  • -A, --insert-after <INSERT_AFTER> — Insert the new change after the given commit(s)
  • -B, --insert-before <INSERT_BEFORE> — Insert the new change before the given commit(s)

jj next

Move the working-copy commit to the child revision

The command creates a new empty working copy revision that is the child of a descendant offset revisions ahead of the parent of the current working copy.

For example, when the offset is 1:

D        D @
|        |/
C @  =>  C
|/       |
B        B

If --edit is passed, the working copy revision is changed to the child of the current working copy revision.

D        D
|        |
C        C
|        |
B   =>   @
|        |
@        A
If your working-copy commit already has visible children, then --edit is implied.

Usage: jj next [OPTIONS] [OFFSET]

Arguments:

  • <OFFSET> — How many revisions to move forward. Advances to the next child by default

    Default value: 1

Options:
  • -e, --edit — Instead of creating a new working-copy commit on top of the target commit (like jj new), edit the target commit directly (like jj edit)
  • --conflict — Jump to the next conflicted descendant

jj obslog

Show how a change has evolved over time

Lists the previous commits which a change has pointed to. The current commit of a change evolves when the change is updated, rebased, etc.

Name is derived from Merciual's obsolescence markers.

Usage: jj obslog [OPTIONS]

Options:

  • -r, --revision <REVISION>

    Default value: @

  • -n, --limit <LIMIT> — Limit number of revisions to show

  • --no-graph — Don't show the graph, show a flat list of revisions

  • -T, --template <TEMPLATE> — Render each revision using the given template

    For the syntax, see https://github.com/martinvonz/jj/blob/main/docs/templates.md

  • -p, --patch — Show patch compared to the previous version of this change

    If the previous version has different parents, it will be temporarily rebased to the parents of the new version, so the diff is not contaminated by unrelated changes.

  • -s, --summary — For each path, show only whether it was modified, added, or deleted

  • --stat — Show a histogram of the changes

  • --types — For each path, show only its type before and after

    The diff is shown as two letters. The first letter indicates the type before and the second letter indicates the type after. '-' indicates that the path was not present, 'F' represents a regular file, `L' represents a symlink, 'C' represents a conflict, and 'G' represents a Git submodule.

  • --name-only — For each path, show only its path

    Typically useful for shell commands like: jj diff -r @- --name_only | xargs perl -pi -e's/OLD/NEW/g

  • --git — Show a Git-format diff

  • --color-words — Show a word-level diff with changes indicated only by color

jj operation restore

Create a new operation that restores the repo to an earlier state

This restores the repo to the state at the specified operation, effectively undoing all later operations. It does so by creating a new operation.

Usage: jj operation restore [OPTIONS] <OPERATION>

Arguments:

  • <OPERATION> — The operation to restore to

    Use jj op log to find an operation to restore to. Use e.g. jj --at-op=<operation ID> log before restoring to an operation to see the state of the repo at that operation.

    Default value: @

Options:
  • --no-graph — Don't show the graph, show a flat list of modified changes

  • -p, --patch — Show patch of modifications to changes

    Typically useful for shell commands like: jj diff -r @- --name_only | xargs perl -pi -e's/OLD/NEW/g

  • --git — Show a Git-format diff

  • --color-words — Show a word-level diff with changes indicated only by color
  • --tool <TOOL> — Generate diff by external command

    This option is EXPERIMENTAL.

    Default values: repo, remote-tracking

    Possible values:

    • repo: The jj repo state and local branches
    • remote-tracking: The remote-tracking branches. Do not restore these if you'd like to push after the undo

jj parallelize

Parallelize revisions by making them siblings

Running jj parallelize 1::2 will transform the history like this: 

3
|             3
2            / \
|    ->     1   2
1            \ /
|             0
0

The command effectively says "these revisions are actually independent", meaning that they should no longer be ancestors/descendants of each other. However, revisions outside the set that were previously ancestors of a revision in the set will remain ancestors of it. For example, revision 0 above remains an ancestor of both 1 and 2. Similarly, revisions outside the set that were previously descendants of a revision in the set will remain descendants of it. For example, revision 3 above remains a descendant of both 1 and 2.

Therefore, jj parallelize '1 | 3' is a no-op. That's because 2, which is not in the target set, was a descendant of 1 before, so it remains a descendant, and it was an ancestor of 3 before, so it remains an ancestor.

Usage: jj parallelize [REVISIONS]...

Arguments:
  • <REVISIONS> — Revisions to parallelize

jj prev

Change the working copy revision relative to the parent revision

The command creates a new empty working copy revision that is the child of an ancestor offset revisions behind the parent of the current working copy.

For example, when the offset is 1:

D @      D
|/       |
A   =>   A @
|        |/
B        B

If --edit is passed, the working copy revision is changed to the parent of the current working copy revision.

D @      D
|/       |
C   =>   @
|        |
B        B
|        |
A        A
If the working copy revision already has visible children, then --edit is implied.

Usage: jj prev [OPTIONS] [OFFSET]

Arguments:

  • <OFFSET> — How many revisions to move backward. Moves to the parent by default

    Default value: 1

Options:
  • -e, --edit — Edit the parent directly, instead of moving the working-copy commit
  • --conflict — Jump to the previous conflicted ancestor

jj rebase

Move revisions to different parent(s)

There are three different ways of specifying which revisions to rebase: -b to rebase a whole branch, -s to rebase a revision and its descendants, and -r to rebase a single commit. If none of them is specified, it defaults to -b @.

With -s, the command rebases the specified revision and its descendants onto the destination. For example, jj rebase -s M -d O would transform your history like this (letters followed by an apostrophe are post-rebase versions):

O           N'
|           |
| N         M'
| |         |
| M         O
| |    =>   |
| | L       | L
| |/        | |
| K         | K
|/          |/
J           J

With -b, the command rebases the whole "branch" containing the specified revision. A "branch" is the set of commits that includes:

  • the specified revision and ancestors that are not also ancestors of the destination
  • all descendants of those commits

In other words, jj rebase -b X -d Y rebases commits in the revset (Y..X):: (which is equivalent to jj rebase -s 'roots(Y..X)' -d Y for a single root). For example, either jj rebase -b L -d O or jj rebase -b M -d O would transform your history like this (because L and M are on the same "branch", relative to the destination):

O           N'
|           |
| N         M'
| |         |
| M         | L'
| |    =>   |/
| | L       K'
| |/        |
| K         O
|/          |
J           J

With -r, the command rebases only the specified revisions onto the destination. Any "hole" left behind will be filled by rebasing descendants onto the specified revision's parent(s). For example, jj rebase -r K -d M would transform your history like this:

M          K'
|          |
| L        M
| |   =>   |
| K        | L'
|/         |/
J          J

Note that you can create a merge commit by repeating the -d argument. For example, if you realize that commit L actually depends on commit M in order to work (in addition to its current parent K), you can run jj rebase -s L -d K -d M:

M          L'
|          |\
| L        M |
| |   =>   | |
| K        | K
|/         |/
J          J

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj rebase [OPTIONS] <--destination <DESTINATION>|--insert-after <INSERT_AFTER>|--insert-before <INSERT_BEFORE>>

Options:

  • -b, --branch <BRANCH> — Rebase the whole branch relative to destination's ancestors (can be repeated)

    jj rebase -b=br -d=dst is equivalent to jj rebase '-s=roots(dst..br)' -d=dst.

    If none of -b, -s, or -r is provided, then the default is -b @.

  • -s, --source <SOURCE> — Rebase specified revision(s) together with their trees of descendants (can be repeated)

    Each specified revision will become a direct child of the destination revision(s), even if some of the source revisions are descendants of others.

    If none of -b, -s, or -r is provided, then the default is -b @.

  • -r, --revisions <REVISIONS> — Rebase the given revisions, rebasing descendants onto this revision's parent(s)

    Unlike -s or -b, you may jj rebase -r a revision A onto a descendant of A.

    If none of -b, -s, or -r is provided, then the default is -b @.

  • -d, --destination <DESTINATION> — The revision(s) to rebase onto (can be repeated to create a merge commit)

  • -A, --insert-after <INSERT_AFTER> — The revision(s) to insert after (can be repeated to create a merge commit)

    Only works with -r.

  • -B, --insert-before <INSERT_BEFORE> — The revision(s) to insert before (can be repeated to create a merge commit)

    Only works with -r.

  • --skip-emptied — If true, when rebasing would produce an empty commit, the commit is abandoned. It will not be abandoned if it was already empty before the rebase. Will never skip merge commits with multiple non-empty parents

jj resolve

Resolve a conflicted file with an external merge tool

Only conflicts that can be resolved with a 3-way merge are supported. See docs for merge tool configuration instructions.

Note that conflicts can also be resolved without using this command. You may edit the conflict markers in the conflicted file directly with a text editor.

Usage: jj resolve [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Restrict to these paths when searching for a conflict to resolve. We will attempt to resolve the first conflict we can find. You can use the --list argument to find paths to use here
Options:

  • -r, --revision <REVISION>

    Default value: @

  • -l, --list — Instead of resolving one conflict, list all the conflicts

  • --tool <NAME> — Specify 3-way merge tool to be used

jj restore

Restore paths from another revision

That means that the paths get the same content in the destination (--to) as they had in the source (--from). This is typically used for undoing changes to some paths in the working copy (jj restore <paths>).

If only one of --from or --to is specified, the other one defaults to the working copy.

When neither --from nor --to is specified, the command restores into the working copy from its parent(s). jj restore without arguments is similar to jj abandon, except that it leaves an empty revision with its description and other metadata preserved.

See jj diffedit if you'd like to restore portions of files rather than entire files.

Usage: jj restore [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Restore only these paths (instead of all paths)
Options:
  • --from <FROM> — Revision to restore from (source)
  • --to <TO> — Revision to restore into (destination)

  • -c, --changes-in <REVISION> — Undo the changes in a revision as compared to the merge of its parents.

    This undoes the changes that can be seen with jj diff -r REVISION. If REVISION only has a single parent, this option is equivalent to jj restore --to REVISION --from REVISION-.

    The default behavior of jj restore is equivalent to jj restore --changes-in @.

jj root

Show the current workspace root directory

Usage: jj root

jj show

Show commit description and changes in a revision

Usage: jj show [OPTIONS] [REVISION]

Arguments:

  • <REVISION> — Show changes in this revision, compared to its parent(s)

    Default value: @

Options:

  • -T, --template <TEMPLATE> — Render a revision using the given template

    For the syntax, see https://github.com/martinvonz/jj/blob/main/docs/templates.md

  • -s, --summary — For each path, show only whether it was modified, added, or deleted

  • --stat — Show a histogram of the changes

  • --types — For each path, show only its type before and after

    The diff is shown as two letters. The first letter indicates the type before and the second letter indicates the type after. '-' indicates that the path was not present, 'F' represents a regular file, `L' represents a symlink, 'C' represents a conflict, and 'G' represents a Git submodule.

  • --name-only — For each path, show only its path

    Typically useful for shell commands like: jj diff -r @- --name_only | xargs perl -pi -e's/OLD/NEW/g

  • --git — Show a Git-format diff

  • --color-words — Show a word-level diff with changes indicated only by color
  • --tool <TOOL> — Generate diff by external command
  • --context <CONTEXT> — Number of lines of context to show

jj sparse

Manage which paths from the working-copy commit are present in the working copy

Usage: jj sparse <COMMAND>

Subcommands:
  • edit — Start an editor to update the patterns that are present in the working copy
  • list — List the patterns that are currently present in the working copy
  • reset — Reset the patterns to include all files in the working copy
  • set — Update the patterns that are present in the working copy

jj sparse edit

Start an editor to update the patterns that are present in the working copy

Usage: jj sparse edit

jj sparse list

List the patterns that are currently present in the working copy

By default, a newly cloned or initialized repo will have have a pattern matching all files from the repo root. That pattern is rendered as . (a single period).

Usage: jj sparse list

jj sparse reset

Reset the patterns to include all files in the working copy

Usage: jj sparse reset

jj sparse set

Update the patterns that are present in the working copy

For example, if all you need is the README.md and the lib/ directory, use jj sparse set --clear --add README.md --add lib. If you no longer need the lib directory, use jj sparse set --remove lib.

Usage: jj sparse set [OPTIONS]

Options:
  • --add <ADD> — Patterns to add to the working copy
  • --remove <REMOVE> — Patterns to remove from the working copy
  • --clear — Include no files in the working copy (combine with --add)

jj split

Split a revision in two

Starts a diff editor on the changes in the revision. Edit the right side of the diff until it has the content you want in the first revision. Once you close the editor, your edited content will replace the previous revision. The remaining changes will be put in a new revision on top.

If the change you split had a description, you will be asked to enter a change description for each commit. If the change did not have a description, the second part will not get a description, and you will be asked for a description only for the first part.

Splitting an empty commit is not supported because the same effect can be achieved with jj new.

Usage: jj split [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Put these paths in the first commit
Options:
  • -i, --interactive — Interactively choose which parts to split. This is the default if no paths are provided
  • --tool <NAME> — Specify diff editor to be used (implies --interactive)

  • -r, --revision <REVISION> — The revision to split

    Default value: @

  • -p, --parallel — Split the revision into two parallel revisions instead of a parent and child

jj squash

Move changes from a revision into another revision

With the -r option, moves the changes from the specified revision to the parent revision. Fails if there are several parent revisions (i.e., the given revision is a merge).

With the --from and/or --into options, moves changes from/to the given revisions. If either is left out, it defaults to the working-copy commit. For example, jj squash --into @-- moves changes from the working-copy commit to the grandparent.

If, after moving changes out, the source revision is empty compared to its parent(s), and --keep-emptied is not set, it will be abandoned. Without --interactive or paths, the source revision will always be empty.

If the source became empty and both the source and destination had a non-empty description, you will be asked for the combined description. If either was empty, then the other one will be used.

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj squash [OPTIONS] [PATHS]...

Arguments:
  • <PATHS> — Move only changes to these paths (instead of all paths)
Options:
  • -r, --revision <REVISION> — Revision to squash into its parent (default: @)
  • --from <FROM> — Revision(s) to squash from (default: @)
  • --into <INTO> — Revision to squash into (default: @)
  • -m, --message <MESSAGE> — The description to use for squashed revision (don't open editor)
  • -u, --use-destination-message — Use the description of the destination revision and discard the description(s) of the source revision(s)
  • -i, --interactive — Interactively choose which parts to squash
  • --tool <NAME> — Specify diff editor to be used (implies --interactive)
  • --keep-emptied — The source revision will not be abandoned

jj status

jj undo

Undo an operation (shortcut for jj op undo)

Usage: jj undo [OPTIONS] [OPERATION]

Arguments:

  • <OPERATION> — The operation to undo

    Use jj op log to find an operation to undo.

    Default value: @

Options:

  • --what <WHAT> — What portions of the local state to restore (can be repeated)

    This option is EXPERIMENTAL.

    Default values: repo, remote-tracking

    Possible values:

    • repo: The jj repo state and local branches
    • remote-tracking: The remote-tracking branches. Do not restore these if you'd like to push after the undo

jj unsquash

Move changes from a revision's parent into the revision

After moving the changes out of the parent, the child revision will have the same content state as before. If moving the change out of the parent change made it empty compared to its parent, it will be abandoned. Without --interactive, the parent change will always become empty.

If the source became empty and both the source and destination had a non-empty description, you will be asked for the combined description. If either was empty, then the other one will be used.

If a working-copy commit gets abandoned, it will be given a new, empty commit. This is true in general; it is not specific to this command.

Usage: jj unsquash [OPTIONS]

Options:

  • -r, --revision <REVISION>

    Default value: @

  • -i, --interactive — Interactively choose which parts to unsquash

  • --tool <NAME> — Specify diff editor to be used (implies --interactive)

jj untrack

Stop tracking specified paths in the working copy

Usage: jj untrack <PATHS>...

Arguments:

  • <PATHS> — Paths to untrack. They must already be ignored.

    The paths could be ignored via a .gitignore or .git/info/exclude (in colocated repos).

jj version

Display version information

Usage: jj version

jj workspace

Commands for working with workspaces

Workspaces let you add additional working copies attached to the same repo. A common use case is so you can run a slow build or test in one workspace while you're continuing to write code in another workspace.

Each workspace has its own working-copy commit. When you have more than one workspace attached to a repo, they are indicated by <workspace name>@ in jj log.

Each workspace also has own sparse patterns.

Usage: jj workspace <COMMAND>

Subcommands:
  • add — Add a workspace
  • forget — Stop tracking a workspace's working-copy commit in the repo
  • list — List workspaces
  • root — Show the current workspace root directory
  • update-stale — Update a workspace that has become stale

jj workspace add

Add a workspace

Sparse patterns will be copied over from the current workspace.

Usage: jj workspace add [OPTIONS] <DESTINATION>

Arguments:
  • <DESTINATION> — Where to create the new workspace
Options:

  • --name <NAME> — A name for the workspace

    To override the default, which is the basename of the destination directory.

  • -r, --revision <REVISION> — A list of parent revisions for the working-copy commit of the newly created workspace. You may specify nothing, or any number of parents.

    If no revisions are specified, the new workspace will be created, and its working-copy commit will exist on top of the parent(s) of the working-copy commit in the current workspace, i.e. they will share the same parent(s).

    If any revisions are specified, the new workspace will be created, and the new working-copy commit will be created with all these revisions as parents, i.e. the working-copy commit will exist as if you had run jj new r1 r2 r3 ....

jj workspace forget

Stop tracking a workspace's working-copy commit in the repo

The workspace will not be touched on disk. It can be deleted from disk before or after running this command.

Usage: jj workspace forget [WORKSPACES]...

Arguments:
  • <WORKSPACES> — Names of the workspaces to forget. By default, forgets only the current workspace

jj workspace list

List workspaces

Usage: jj workspace list

jj workspace root

Show the current workspace root directory

Usage: jj workspace root

jj workspace update-stale

Update a workspace that has become stale

For information about stale working copies, see https://github.com/martinvonz/jj/blob/main/docs/working-copy.md.

Usage: jj workspace update-stale
