NAME

arc - arcanist, a code review and revision management utility

SYNOPSIS

arc command [options] [args] This help file provides a detailed command reference.

COMMAND REFERENCE

alias
alias command
alias command target -- [options]
 
Supports: cli Create an alias from command to target (optionally, with options). For example:
 
  arc alias fpatch patch -- --force
 
...will create a new 'arc' command, 'arc fpatch', which invokes 'arc patch --force ...' when run. NOTE: use "--" before specifying options!
 
If you start an alias with "!", the remainder of the alias will be invoked as a shell command. For example, if you want to implement 'arc ls', you can do so like this:
 
  arc alias ls '!ls'
 
You can now run "arc ls" and it will behave like "ls". Of course, this example is silly and would make your life worse.
 
You can not overwrite builtins, including 'alias' itself. The builtin will always execute, even if it was added after your alias.
 
To remove an alias, run:
 
  arc alias fpatch
 
Without any arguments, 'arc alias' will list aliases.
amend [--revision revision_id] [--show]
 
Supports: git, hg Amend the working copy, synchronizing the local commit message from Differential.
 
Supported in Mercurial 2.2 and newer.
--revision revision_id
 
Use the message from a specific revision. If you do not specify a revision, arc will guess which revision is in the working copy.
--show
 
Show the amended commit message, without modifying the working copy.
anoid
 
There's only one way to find out...
backout
 
Reverts/backouts on a previous commit. Supports: git, hg
 
Command is used like this: arc backout <commithash> | <diff revision> Entering a differential revision will only work if there is only one commit associated with the revision. This requires your working copy is up to date and that the commit exists in the working copy.
bookmark [options]
bookmark name [start]
 
Supports: hg Alias for arc feature.
--by-status
 
Sort branches by status instead of time.
--output format
 
With 'json', show features in machine-readable JSON format.
--view-all
 
Include closed and abandoned revisions.
branch [options]
branch name [start]
 
Supports: git Alias for arc feature.
--by-status
 
Sort branches by status instead of time.
--output format
 
With 'json', show features in machine-readable JSON format.
--view-all
 
Include closed and abandoned revisions.
browse [options] path ...
browse [options] object ...
 
Supports: git, hg, svn Open a file or object (like a task or revision) in your web browser.
 
  $ arc browse README   # Open a file in Diffusion.
  $ arc browse T123     # View a task.
  $ arc browse HEAD     # View a symbolic commit.
 
Set the 'browser' value using 'arc set-config' to select a browser. If no browser is set, the command will try to guess which browser to use.
--branch branch_name
 
Default branch name to view on server. Defaults to "master".
--force
 
Open arguments as paths, even if they do not exist in the working copy.
call-conduit method
 
Supports: http, https Allows you to make a raw Conduit method call:
 
  - Run this command from a working directory.
  - Call parameters are REQUIRED and read as a JSON blob from stdin.
  - Results are written to stdout as a JSON blob.
 
This workflow is primarily useful for writing scripts which integrate with Phabricator. Examples:
 
  $ echo '{}' | arc call-conduit conduit.ping
  $ echo '{"phid":"PHID-FILE-xxxx"}' | arc call-conduit file.download
close task_id [options]
Close a task or otherwise update its status.
--list-statuses
Show available status options and exit.
--message comment, -m comment
Provide a comment with your status change.
--status status, -s status
Specify a new status. Valid status options can be seen with the `list-statuses` argument.
close-revision [options] revision
 
Supports: git, hg, svn Close a revision which has been committed (svn) or pushed (git, hg). You should not normally need to do this: arc commit (svn), arc amend (git, hg), arc land (git, hg), or repository tracking on the master remote repository should do it for you. However, if these mechanisms have failed for some reason you can use this command to manually change a revision status from "Accepted" to "Closed".
--finalize
 
Close only if the repository is untracked and the revision is accepted. Continue even if the close can't happen. This is a soft version of '' used by other workflows.
--quiet
 
Do not print a success message.
commit [--revision revision_id] [--show]
 
Supports: svn Commit a revision which has been accepted by a reviewer.
--revision revision_id
 
Commit a specific revision. If you do not specify a revision, arc will look for committable revisions.
--show
 
Show the command which would be issued, but do not actually commit anything.
cover [--rev revision] [path ...]
 
Supports: svn, git, hg Cover your... professional reputation. Show blame for the lines you changed in your working copy (svn) or since some commit (hg, git). This will take a minute because blame takes a minute, especially under SVN.
--rev revision
 
Supports: git, hg Cover changes since a specific revision.
diff [paths] (svn)
diff [commit] (git, hg)
 
Supports: git, svn, hg Generate a Differential diff or revision from local changes.
 
Under git and mercurial, you can specify a commit (like HEAD^^^ or master) and Differential will generate a diff against the merge base of that commit and your current working directory parent.
 
Under svn, you can choose to include only some of the modified files in the working copy in the diff by specifying their paths. If you omit paths, all changes are included in the diff.
--add-all, -a
 
Automatically add all unstaged and uncommitted files to the commit.
--advice
 
Require excuse for lint advice in addition to lint warnings and errors.
--allow-untracked
 
Skip checks for untracked files in the working copy.
--amend-all
 
When linting git repositories, amend HEAD with all patches suggested by lint without prompting.
--amend-autofixes
 
When linting git repositories, amend HEAD with autofix patches suggested by lint without prompting.
--apply-patches
 
Apply patches suggested by lint to the working copy without prompting.
--base rules
 
Supports: git, hg Additional rules for determining base revision.
--browse
 
After creating a diff or revision, open it in a web browser.
--cache bool
 
    0 to disable lint cache, 1 to enable (default).
--cc usernames
 
When creating a revision, add CCs.
--coverage
 
Always enable coverage information.
--create
 
Always create a new revision.
--edit
 
Supports: git, hg When updating a revision under git, edit revision information before updating.
--encoding encoding
 
Attempt to convert non UTF-8 hunks into specified encoding.
--excuse excuse
 
Provide a prepared in advance excuse for any lints/tests shall they fail.
--head commit
 
Supports: git Specify the end of the commit range. This disables many Arcanist/Phabricator features which depend on having access to the working copy.
--ignore-unsound-tests
 
Ignore unsound test failures without prompting.
--json
 
Emit machine-readable JSON. EXPERIMENTAL! Probably does not work!
--less-context
 
Normally, files are diffed with full context: the entire file is sent to Differential so reviewers can 'show more' and see it. If you are making changes to very large files with tens of thousands of lines, this may not work well. With this flag, a diff will be created that has only a few lines of context.
--lintall
 
Raise all lint warnings, not just those on lines you changed.
--message message, -m message
 
When updating a revision, use the specified message instead of prompting.
--message-file file, -F file
 
When creating a revision, read revision information from this file.
--never-apply-patches
 
Never apply patches suggested by lint.
--no-amend
 
Never amend commits in the working copy with lint patches.
--no-coverage
 
Always disable coverage information.
--no-diff
 
Only run lint and unit tests. Intended for internal use.
--nolint
 
Do not run lint.
--nounit
 
Do not run unit tests.
--only
 
Only generate a diff, without running lint, unit tests, or other auxiliary steps. See also --preview.
--only-new bool
 
Display only lint messages not present in the original code.
--plan-changes
 
Create or update a revision without requesting a code review.
--preview
 
Instead of creating or updating a revision, only create a diff, which you may later attach to a revision. This still runs lint unit tests. See also --only.
--raw
 
Read diff from stdin, not from the working copy. This disables many Arcanist/Phabricator features which depend on having access to the working copy.
--raw-command command
 
Generate diff by executing a specified command, not from the working copy. This disables many Arcanist/Phabricator features which depend on having access to the working copy.
--reviewers usernames
 
When creating a revision, add reviewers.
--skip-binaries
 
Do not upload binaries (like images).
--skip-staging
 
Do not copy changes to the staging area.
--uncommitted

--update revision_id
 
Always update a specific revision.
--use-commit-message commit, -C commit
 
Supports: git Read revision information from a specific commit.

Supports: hg, git When creating a revision, try to use the working copy commit message verbatim, without prompting to edit it. When updating a revision, update some fields from the local commit message.
download file [--as name] [--show]
 
Supports: filesystems Download a file to local disk, e.g.:
 
  $ arc download F33              # Download file 'F33'
--as name
 
Save the file with a specific name rather than the default.

--arcbundle file
 
Export change as an arc bundle. This format can represent all changes. These bundles can be applied with 'arc patch'.
--diff diff_id
 
Instead of exporting changes from the working copy, export them from a Differential diff.
--encoding encoding
 
Attempt to convert non UTF-8 patch into specified encoding.
--git
 
Export change as a git patch. This format is more complete than unified, but less complete than arc bundles. These patches can be applied with 'git apply' or 'arc patch'.
--revision revision_id
 
Instead of exporting changes from the working copy, export them from a Differential revision.
--unified
 
Export change as a unified patch. This format is less complete than git patches or arc bundles. These patches can be applied with 'patch' or 'arc patch'.
feature [options]
feature name [start]
 
Supports: git, hg A wrapper on 'git branch' or 'hg bookmark'.
 
Without name, it lists the available branches and their revision status.
 
With name, it creates or checks out a branch. If the branch name doesn't exist and is in format D123 then the branch of revision D123 is checked out. Use start to specify where the new branch will start. Use 'arc.feature.start.default' to set the default feature start location.
--by-status
 
Sort branches by status instead of time.
--output format
 
With 'json', show features in machine-readable JSON format.
--view-all
 
Include closed and abandoned revisions.
flag [object ...]
flag object --clear
flag object [--edit] [--color color] [--note note]
 
In the first form, list objects you've flagged. You can provide the names of one or more objects (Maniphest tasks T?[7m#, Differential revisions D?[m#, Diffusion references rXXX???, or PHIDs PHID-XXX-???) to print only flags for those objects.
 
In the second form, clear an existing flag on one object.
 
In the third form, create or update a flag on one object. Color defaults to blue and note to empty, but if you omit both you must pass --edit.
--clear
 
Delete the flag on an object.
--color color
 
Set the color of a flag.
--edit
 
Edit the flag on an object.
--note note
 
Set the note on a flag.
get-config [options] -- [name ...]
 
Supports: cli Reads an arc configuration option. With no argument, reads all options.
 
With --verbose, shows detailed information about one or more options.
--verbose
 
Show detailed information about options.
help [command]
help --full
 
Supports: english Shows this help. With command, shows help about a specific command.
--full
 
Print detailed information about each command.
install-certificate [uri]
 
Supports: http, https Installs Conduit credentials into your ~/.arcrc for the given install of Phabricator. You need to do this before you can use 'arc', as it enables 'arc' to link your command-line activity with your account on the web. Run this command from within a project directory to install that project's certificate, or specify an explicit URI (like "https://phabricator.example.com/").
land [options] [ref]
 
Supports: git, hg
 
Publish an accepted revision after review. This command is the last step in the standard Differential pre-publish code review workflow.
 
This command merges and pushes changes associated with an accepted revision that are currently sitting in ref, which is usually the name of a local branch. Without ref, the current working copy state will be used.
 
Under Git: branches, tags, and arbitrary commits (detached HEADs) may be landed.
 
Under Mercurial: branches and bookmarks may be landed, but only onto a target of the same type. See T3855.
 
The workflow selects a target branch to land onto and a remote where the change will be pushed to.
 
A target branch is selected by examining these sources in order:
 
  - the B<--onto> flag;
  - the upstream of the current branch, recursively (Git only);
  - the I<arc.land.onto.default> configuration setting;
  - or by falling back to a standard default:
    - "master" in Git;
    - "default" in Mercurial.
 
A remote is selected by examining these sources in order:
 
  - the B<--remote> flag;
  - the upstream of the current branch, recursively (Git only);
  - or by falling back to a standard default:
    - "origin" in Git;
    - the default remote in Mercurial.
 
After selecting a target branch and a remote, the commits which will be landed are printed.
 
With --preview, execution stops here, before the change is merged.
 
The change is merged with the changes in the target branch, following these rules:
 
In repositories with mutable history or with --squash, this will perform a squash merge (the entire branch will be represented as one commit after the merge).
 
In repositories with immutable history or with --merge, this will perform a strict merge (a merge commit will always be created, and local commits will be preserved).
 
The resulting commit will be given an up-to-date commit message describing the final state of the revision in Differential.
 
In Git, the merge occurs in a detached HEAD. The local branch reference (if one exists) is not updated yet.
 
With --hold, execution stops here, before the change is pushed.
 
The change is pushed into the remote.
 
Consulting mystical sources of power, the workflow makes a guess about what state you wanted to end up in after the process finishes and the working copy is put into that state.
 
The branch which was landed is deleted, unless the --keep-branch flag was passed or the landing branch is the same as the target branch.
--delete-remote
 
Delete the feature branch in the remote after landing it.
--hold
 
Prepare the change to be pushed, but do not actually push it.
--keep-branch
 
Keep the feature branch after pushing changes to the remote (by default, it is deleted).
--merge
 
Supports: git Perform a --no-ff merge, not a --squash merge. If the project is marked as having an immutable history, this is the default behavior.
--onto master
 
Land feature branch onto a branch other than the default ('master' in git, 'default' in hg). You can change the default by setting 'arc.land.onto.default' with `arc set-config` or for the entire project in .arcconfig.
--preview
 
Prints the commits that would be landed. Does not actually modify or land the commits.
--remote origin
 
Push to a remote other than the default ('origin' in git).
--revision id
 
Use the message from a specific revision, rather than inferring the revision based on branch content.
--squash
 
Perform a --squash merge, not a --no-ff merge. If the project is marked as having a mutable history, this is the default behavior.
--update-with-merge
 
Supports: git When updating the feature branch, use merge instead of rebase. This is the default behavior. Setting arc.land.update.default to 'merge' can also be used to make this the default.
--update-with-rebase
 
Supports: git When updating the feature branch, use rebase instead of merge. This might make things work better in some cases. Set arc.land.update.default to 'rebase' to make this the default.
liberate [path]
 
Supports: libphutil Create or update a libphutil library, generating required metadata files like init.php.
--all
 
Drop the module cache before liberating. This will completely reanalyze the entire library. Thorough, but slow!
--force-update
 
Force the library map to be updated, even in the presence of lint errors.
--library-name name
 
Use a flag for library name rather than awaiting user input.
lint [options] [paths]
lint [options] --rev [rev]
 
Supports: git, svn, hg Run static analysis on changes to check for mistakes. If no files are specified, lint will be run on all files which have been modified.

When linting git repositories, amend HEAD with all patches suggested by lint without prompting.
--amend-autofixes
 
When linting git repositories, amend HEAD with autofix patches suggested by lint without prompting.
--apply-patches
 
Apply patches suggested by lint to the working copy without prompting.
--cache bool
 
    0 to disable cache, 1 to enable. The default value is
    determined by 'arc.lint.cache' in configuration, which defaults
    to off. See notes in 'arc.lint.cache'.
--engine classname
 
Override configured lint engine for this project.
--everything
 
Lint all files in the project.
--lintall
 
Show all lint warnings, not just those on changed lines. When paths are specified, this is the default behavior.
--never-apply-patches
 
Never apply patches suggested by lint.
--only-changed
 
Show lint warnings just on changed lines. When no paths are specified, this is the default. This differs from only-new in cases where line modifications introduce lint on other unmodified lines.
--only-new bool
 
Supports: git, hg Display only messages not present in the original code.
--outfile path
 
Output the linter results to a file. Defaults to stdout.
--output format
 
With 'summary', show lint warnings in a more compact format. With 'json', show lint warnings in machine-readable JSON format. With 'none', show no lint warnings. With 'compiler', show lint warnings in suitable for your editor. With 'xml', show lint warnings in the Checkstyle XML format.
--rev revision
 
Supports: git, hg Lint changes since a specific revision.
--severity string
 
Set minimum message severity. One of: 'advice', 'autofix', 'warning', 'error', 'disabled'. Defaults to 'advice'.
linters [options] [name]
 
Supports: cli List the available and configured linters, with information about what they do and which versions are installed.
 
if name is provided, the linter with that name will be displayed.

Title for the paste.
patch D12345
patch --revision revision_id
patch --diff diff_id
patch --patch file
patch --arcbundle bundlefile
 
Supports: git, svn, hg Apply the changes in a Differential revision, patchfile, or arc bundle to the working copy.
--arcbundle bundlefile
 
Apply changes from an arc bundle generated with 'arc export'.
--diff diff_id
 
Apply changes from a Differential diff. Normally you want to use --revision to get the most recent changes, but you can specifically apply an out-of-date diff or a diff which was never attached to a revision by using this flag.
--encoding encoding
 
Attempt to convert non UTF-8 patch into specified encoding.
--force
 
Do not run any sanity checks.
--nobranch
 
Supports: git, hg Normally, a new branch (git) or bookmark (hg) is created and then the patch is applied and committed in the new branch/bookmark. This flag cherry-picks the resultant commit onto the original branch and deletes the temporary branch.
--nocommit
 
Supports: git, hg Normally under git/hg, if the patch is successful, the changes are committed to the working copy. This flag prevents the commit.
--patch patchfile
 
Apply changes from a git patchfile or unified patchfile.
--revision revision_id
 
Apply changes from a Differential revision, using the most recent diff that has been attached to it. You can run 'arc patch D12345' as a shorthand.

Supports: git, hg Normally, if a patch has dependencies that are not present in the working copy, arc tries to apply them as well. This flag prevents such work.
--update
 
Supports: git, svn, hg Update the local working copy before applying the patch.
revert Please use arc backout instead
set-config [options] -- name value
 
Supports: cli Sets an arc configuration option.
 
Options are either user (apply to all arc commands you invoke from the current user) or local (apply only to the current working copy). By default, user configuration is written. Use --local to write local configuration.
