add

hg add [OPTION]... [FILE]...

Schedule files to be version controlled and added to the repository.

The files will be added to the repository at the next commit. To undo an add before that, see hg forget.

If no names are given, add all files to the repository.

$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c

Returns 0 if all files are successfully added.

Options:

addremove

hg addremove [OPTION]... [FILE]...

Add all new files and remove all missing files from the repository.

New files are ignored if they match any of the patterns in .hgignore. As with add, these changes take effect at the next commit.

Use the -s/--similarity option to detect renamed files. With a parameter greater than 0, this compares every removed file with every added file and records those similar enough as renames. This option takes a percentage between 0 (disabled) and 100 (files must be identical) as its parameter. Detecting renamed files this way can be expensive. After using this option, hg status -C can be used to check which files were identified as moved or renamed. If this option is not specified, only renames of identical files are detected.

Returns 0 if all files are successfully added.

Options:

annotate

hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...

List changes in files, showing the revision id responsible for each line

This command is useful for discovering when a change was made and by whom.

Without the -a/--text option, annotate will avoid processing files it detects as binary. With -a, annotate will annotate the file anyway, although the results will probably be neither useful nor desirable.

Returns 0 on success.

Options:

archive

hg archive [OPTION]... DEST

By default, the revision used is the parent of the working directory; use -r/--rev to specify a different revision.

The archive type is automatically detected based on file extension (or override using -t/--type).

Valid types are:

The exact name of the destination archive or directory is given using a format string; see hg help export for details.

Each member added to an archive file has a directory prefix prepended. Use -p/--prefix to specify a format string for the prefix. The default is the basename of the archive, with suffixes removed.

Returns 0 on success.

Options:

backout

hg backout [OPTION]... [-r] REV

Prepare a new changeset with the effect of REV undone in the current working directory.

If REV is the parent of the working directory, then this new changeset is committed automatically. Otherwise, hg needs to merge the changes and the merged result is left uncommitted.

See hg help dates for a list of formats valid for -d/--date.

Returns 0 on success.

Options:

bisect

hg bisect [-gbsr] [-U] [-c CMD] [REV]

This command helps to find changesets which introduce problems. To use, mark the earliest changeset you know exhibits the problem as bad, then mark the latest changeset which is free from the problem as good. Bisect will update your working directory to a revision for testing (unless the -U/--noupdate option is specified). Once you have performed tests, mark the working directory as good or bad, and bisect will either update to another candidate changeset or announce that it has found the bad revision.

As a shortcut, you can also use the revision argument to mark a revision as good or bad without checking it out first.

If you supply a command, it will be used for automatic bisection. Its exit status will be used to mark revisions as good or bad: status 0 means good, 125 means to skip the revision, 127 (command not found) will abort the bisection, and any other non-zero exit status means the revision is bad.

Returns 0 on success.

Options:

bookmarks

hg bookmarks [-f] [-d] [-i] [-m NAME] [-r REV] [NAME]

Bookmarks are pointers to certain commits that move when committing. Bookmarks are local. They can be renamed, copied and deleted. It is possible to use hg merge NAME to merge from a given bookmark, and hg update NAME to update to a given bookmark.

You can use hg bookmark NAME to set a bookmark on the working directory's parent revision with the given name. If you specify a revision using -r REV (where REV may be an existing bookmark), the bookmark is assigned to that revision.

Bookmarks can be pushed and pulled between repositories (see hg help push and hg help pull). This requires both the local and remote repositories to support bookmarks. For versions prior to 1.8, this means the bookmarks extension must be enabled.

With -i/--inactive, the new bookmark will not be made the active bookmark. If -r/--rev is given, the new bookmark will not be made active even if -i/--inactive is not given. If no NAME is given, the current active bookmark will be marked inactive.

Options:

branch

hg branch [-fC] [NAME]

With no argument, show the current branch name. With one argument, set the working directory branch name (the branch will not exist in the repository until the next commit). Standard practice recommends that primary development take place on the 'default' branch.

Unless -f/--force is specified, branch will not let you set a branch name that already exists, even if it's inactive.

Use -C/--clean to reset the working directory branch to that of the parent of the working directory, negating a previous branch change.

Use the command hg update to switch to an existing branch. Use hg commit --close-branch to mark this branch as closed.

Returns 0 on success.

Options:

branches

hg branches [-ac]

List the repository's named branches, indicating which ones are inactive. If -c/--closed is specified, also list branches which have been marked closed (see hg commit --close-branch).

If -a/--active is specified, only show active branches. A branch is considered active if it contains repository heads.

Use the command hg update to switch to an existing branch.

Returns 0.

Options:

bundle

hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]

Generate a compressed changegroup file collecting changesets not known to be in another repository.

If you omit the destination repository, then hg assumes the destination will have all the nodes you specify with --base parameters. To create a bundle containing all changesets, use -a/--all (or --base null).

You can change compression method with the -t/--type option. The available compression methods are: none, bzip2, and gzip (by default, bundles are compressed using bzip2).

The bundle file can then be transferred using conventional means and applied to another repository with the unbundle or pull command. This is useful when direct push and pull are not available or when exporting an entire repository is undesirable.

Applying bundles preserves all changeset contents including permissions, copy/rename information, and revision history.

Returns 0 on success, 1 if no changes found.

Options:

cat

hg cat [OPTION]... FILE...

Print the specified files as they were at the given revision. If no revision is given, the parent of the working directory is used, or tip if no revision is checked out.

Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are the same as for the export command, with the following additions:

Returns 0 on success.

Options:

clone

hg clone [OPTION]... SOURCE [DEST]

Create a copy of an existing repository in a new directory.

If no destination directory name is specified, it defaults to the basename of the source.

The location of the source is added to the new repository's .hg/hgrc file, as the default to be used for future pulls.

Only local paths and ssh:// URLs are supported as destinations. For ssh:// destinations, no working directory or .hg/hgrc will be created on the remote side.

To pull only a subset of changesets, specify one or more revisions identifiers with -r/--rev or branches with -b/--branch. The resulting clone will contain only the specified changesets and their ancestors. These options (or 'clone src#rev dest') imply --pull, even for local source repositories. Note that specifying a tag will include the tagged changeset but not the changeset containing the tag.

To check out a particular version, use -u/--update, or -U/--noupdate to create a clone with no working directory.

$ cp -al REPO REPOCLONE

See hg help urls for details on specifying URLs.

Returns 0 on success.

Options:

commit

hg commit [OPTION]... [FILE]...

Commit changes to the given files into the repository. Unlike a centralized SCM, this operation is a local operation. See hg push for a way to actively distribute your changes.

If a list of files is omitted, all changes reported by hg status will be committed.

If you are committing the result of a merge, do not provide any filenames or -I/-X filters.

If no commit message is specified, Mercurial starts your configured editor where you can enter a message. In case your commit fails, you will find a backup of your message in .hg/last-message.txt.

The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in addition to those currently reported by hg status, if there are any. The old commit is stored in a backup bundle in .hg/strip-backup (see hg help bundle and hg help unbundle on how to restore it).

Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor will open with the message of the amended commit.

It is not possible to amend public changesets (see hg help phases) or changesets that have children.

See hg help dates for a list of formats valid for -d/--date.

Returns 0 on success, 1 if nothing changed.

Options:

copy

hg copy [OPTION]... [SOURCE]... DEST

Mark dest as having copies of source files. If dest is a directory, copies are put in that directory. If dest is a file, the source must be a single file.

By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is recorded, but no copying is performed.

This command takes effect with the next commit. To undo a copy before that, see hg revert.

Returns 0 on success, 1 if errors are encountered.

Options:

diff

hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...

Show differences between revisions for the specified files.

Differences between files are shown using the unified diff format.

When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent.

Alternatively you can specify -c/--change with a revision to see the changes in that changeset relative to its first parent.

Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway, probably with undesirable results.

Use the -g/--git option to generate diffs in the git extended diff format. For more information, read hg help diffs.

Returns 0 on success.

Options:

export

hg export [OPTION]... [-o OUTFILESPEC] REV...

Print the changeset header and diffs for one or more revisions.

The information shown in the changeset header is: author, date, branch name (if non-default), changeset hash, parent(s) and commit comment.

Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are as follows:

Without the -a/--text option, export will avoid generating diffs of files it detects as binary. With -a, export will generate a diff anyway, probably with undesirable results.

Use the -g/--git option to generate diffs in the git extended diff format. See hg help diffs for more information.

With the --switch-parent option, the diff will be against the second parent. It can be useful to review a merge.

Returns 0 on success.

Options:

forget

hg forget [OPTION]... FILE...

Mark the specified files so they will no longer be tracked after the next commit.

This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

To undo a forget before the next commit, see hg add.

Returns 0 on success.

Options:

graft

hg graft [OPTION]... REVISION...

This command uses Mercurial's merge logic to copy individual changes from other branches without merging branches in the history graph. This is sometimes known as 'backporting' or 'cherry-picking'. By default, graft will copy user, date, and description from the source changesets.

Changesets that are ancestors of the current revision, that have already been grafted, or that are merges will be skipped.

If a graft merge results in conflicts, the graft process is interrupted so that the current merge can be manually resolved. Once all conflicts are addressed, the graft process can be continued with the -c/--continue option.

Returns 0 on successful completion.

Options:

grep

hg grep [OPTION]... PATTERN [FILE]...

Search revisions of files for a regular expression.

This command behaves differently than Unix grep. It only accepts Python/Perl regexps. It searches repository history, not the working directory. It always prints the revision number in which a match appears.

By default, grep only prints output for the first revision of a file in which it finds a match. To get it to print every revision that contains a change in match status ("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match), use the --all flag.

Returns 0 if a match is found, 1 otherwise.

Options:

heads

hg heads [-ac] [-r STARTREV] [REV]...

With no arguments, show all repository branch heads.

Repository "heads" are changesets with no child changesets. They are where development generally takes place and are the usual targets for update and merge operations. Branch heads are changesets that have no child changeset on the same branch.

If one or more REVs are given, only branch heads on the branches associated with the specified changesets are shown. This means that you can use hg heads foo to see the heads on a branch named foo.

If -c/--closed is specified, also show branch heads marked closed (see hg commit --close-branch).

If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed.

If -t/--topo is specified, named branch mechanics will be ignored and only changesets without children will be shown.

Returns 0 if matching heads are found, 1 if not.

Options:

help

hg help [-ec] [TOPIC]

With no arguments, print a list of commands with short help messages.

Given a topic, extension, or command name, print help for that topic.

Returns 0 if successful.

Options:

identify

hg identify [-nibtB] [-r REV] [SOURCE]

Print a summary identifying the repository state at REV using one or two parent hash identifiers, followed by a "+" if the working directory has uncommitted changes, the branch name (if not default), a list of tags, and a list of bookmarks.

When REV is not given, print a summary of the current state of the repository.

Specifying a path to a repository root or Mercurial bundle will cause lookup to operate on that repository/bundle.

Returns 0 if successful.

Options:

import

hg import [OPTION]... PATCH...

Import a list of patches and commit them individually (unless --no-commit is specified).

If there are outstanding changes in the working directory, import will abort unless given the -f/--force flag.

You can import a patch straight from a mail message. Even patches as attachments work (to use the body part, it must have type text/plain or text/x-patch). From and Subject headers of email message are used as default committer and commit message. All text/plain body parts before first diff are added to commit message.

If the imported patch was generated by hg export, user and description from patch override values from message headers and body. Values given on command line with -m/--message and -u/--user override these.

If --exact is specified, import will set the working directory to the parent of each patch before applying it, and will abort if the resulting changeset has a different ID than the one recorded in the patch. This may happen due to character set problems or other deficiencies in the text patch format.

Use --bypass to apply and commit patches directly to the repository, not touching the working directory. Without --exact, patches will be applied on top of the working directory parent revision.

With -s/--similarity, hg will attempt to discover renames and copies in the patch in the same way as hg addremove.

To read a patch from standard input, use "-" as the patch name. If a URL is specified, the patch will be downloaded from it. See hg help dates for a list of formats valid for -d/--date.

Returns 0 on success.

Options:

incoming

hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]

Show new changesets found in the specified path/URL or the default pull location. These are the changesets that would have been pulled if a pull at the time you issued this command.

For remote repository, using --bundle avoids downloading the changesets twice if the incoming is followed by a pull.

See pull for valid source format details.

Returns 0 if there are incoming changes, 1 otherwise.

Options:

init

hg init [-e CMD] [--remotecmd CMD] [DEST]

Initialize a new repository in the given directory. If the given directory does not exist, it will be created.

If no directory is given, the current directory is used.

It is possible to specify an ssh:// URL as the destination. See hg help urls for more information.

Returns 0 on success.

Options:

locate

hg locate [OPTION]... [PATTERN]...

Print files under Mercurial control in the working directory whose names match the given patterns.

By default, this command searches all directories in the working directory. To search just the current directory and its subdirectories, use "--include .".

If no patterns are given to match, this command prints the names of all files under Mercurial control in the working directory.

If you want to feed the output of this command into the "xargs" command, use the -0 option to both this command and "xargs". This will avoid the problem of "xargs" treating single filenames that contain whitespace as multiple filenames.

Returns 0 if a match is found, 1 otherwise.

Options:

log

hg log [OPTION]... [FILE]

Print the revision history of the specified files or the entire project.

If no revision range is specified, the default is tip:0 unless --follow is set, in which case the working directory parent is used as the starting revision.

File history is shown without following rename or copy history of files. Use -f/--follow with a filename to follow history across renames and copies. --follow without a filename will only show ancestors or descendants of the starting revision.

By default this command prints revision number and changeset id, tags, non-trivial parents, user, date and time, and a summary for each commit. When the -v/--verbose switch is used, the list of changed files and full commit message are shown.

See hg help dates for a list of formats valid for -d/--date.

See hg help revisions and hg help revsets for more about specifying revisions.

See hg help templates for more about pre-packaged styles and specifying custom templates.

Returns 0 on success.

Options:

manifest

hg manifest [-r REV]

Print a list of version controlled files for the given revision. If no revision is given, the first parent of the working directory is used, or the null revision if no revision is checked out.

With -v, print file permissions, symlink and executable bits. With --debug, print file revision hashes.

If option --all is specified, the list of all files from all revisions is printed. This includes deleted and renamed files.

Returns 0 on success.

Options:

merge

hg merge [-P] [-f] [[-r] REV]

The current working directory is updated with all changes made in the requested revision since the last common predecessor revision.

Files that changed between either parent are marked as changed for the next commit and a commit must be performed before any further updates to the repository are allowed. The next commit will have two parents.

--tool can be used to specify the merge tool used for file merges. It overrides the HGMERGE environment variable and your configuration files. See hg help merge-tools for options.

If no revision is specified, the working directory's parent is a head revision, and the current branch contains exactly one other head, the other head is merged with by default. Otherwise, an explicit revision with which to merge with must be provided.

hg resolve must be used to resolve unresolved files.

To undo an uncommitted merge, use hg update --clean . which will check out a clean copy of the original merge parent, losing all changes.

Returns 0 on success, 1 if there are unresolved files.

Options:

outgoing

hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]

Show changesets not found in the specified destination repository or the default push location. These are the changesets that would be pushed if a push was requested.

See pull for details of valid destination formats.

Returns 0 if there are outgoing changes, 1 otherwise.

Options:

parents

hg parents [-r REV] [FILE]

Print the working directory's parent revisions. If a revision is given via -r/--rev, the parent of that revision will be printed. If a file argument is given, the revision in which the file was last changed (before the working directory revision or the argument to --rev if given) is printed.

Returns 0 on success.

Options:

paths

hg paths [NAME]

Show definition of symbolic path name NAME. If no name is given, show definition of all available names.

Option -q/--quiet suppresses all output when searching for NAME and shows only the path names when listing all definitions.

Path names are defined in the [paths] section of your configuration file and in /etc/mercurial/hgrc. If run inside a repository, .hg/hgrc is used, too.

The path names default and default-push have a special meaning. When performing a push or pull operation, they are used as fallbacks if no location is specified on the command-line. When default-push is set, it will be used for push and default will be used for pull; otherwise default is used as the fallback for both. When cloning a repository, the clone source is written as default in .hg/hgrc. Note that default and default-push apply to all inbound (e.g. hg incoming) and outbound (e.g. hg outgoing, hg email and hg bundle) operations.

See hg help urls for more information.

Returns 0 on success.

phase

hg phase [-p|-d|-s] [-f] [-r] REV...

With no argument, show the phase name of specified revisions.

With one of -p/--public, -d/--draft or -s/--secret, change the phase value of the specified revisions.

Unless -f/--force is specified, hg phase won't move changeset from a lower phase to an higher phase. Phases are ordered as follows:

public < draft < secret

Return 0 on success, 1 if no phases were changed or some could not be changed.

Options:

pull

hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]

Pull changes from a remote repository to a local one.

This finds all changes from the repository at the specified path or URL and adds them to a local repository (the current one unless -R is specified). By default, this does not update the copy of the project in the working directory.

Use hg incoming if you want to see what would have been added by a pull at the time you issued this command. If you then decide to add those changes to the repository, you should use hg pull -r X where X is the last changeset listed by hg incoming.

If SOURCE is omitted, the 'default' path will be used. See hg help urls for more information.

Returns 0 on success, 1 if an update had unresolved files.

Options:

push

hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]

Push changesets from the local repository to the specified destination.

This operation is symmetrical to pull: it is identical to a pull in the destination repository from the current one.

By default, push will not allow creation of new heads at the destination, since multiple heads would make it unclear which head to use. In this situation, it is recommended to pull and merge before pushing.

Use --new-branch if you want to allow push to create a new named branch that is not present at the destination. This allows you to only create a new branch without forcing other changes.

Use -f/--force to override the default behavior and push all changesets on all branches.

If -r/--rev is used, the specified revision and all its ancestors will be pushed to the remote repository.

Please see hg help urls for important details about ssh:// URLs. If DESTINATION is omitted, a default path will be used.

Returns 0 if push was successful, 1 if nothing to push.

Options:

recover

hg recover

Recover from an interrupted commit or pull.

This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it.

Returns 0 if successful, 1 if nothing to recover or verify fails.

remove

hg remove [OPTION]... FILE...

Schedule the indicated files for removal from the current branch.

This command schedules the files to be removed at the next commit. To undo a remove before that, see hg revert. To undo added files, see hg forget.

Returns 0 on success, 1 if any warnings encountered.

Options:

rename

hg rename [OPTION]... SOURCE... DEST

Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that directory. If dest is a file, there can only be one source.

By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is recorded, but no copying is performed.

This command takes effect at the next commit. To undo a rename before that, see hg revert.

Returns 0 on success, 1 if errors are encountered.

Options:

resolve

hg resolve [OPTION]... [FILE]...

Merges with unresolved conflicts are often the result of non-interactive merging using the internal:merge configuration setting, or a command-line merge tool like diff3. The resolve command is used to manage the files involved in a merge, after hg merge has been run, and before hg commit is run (i.e. the working directory must have two parents). See hg help merge-tools for information on configuring merge tools.

The resolve command can be used in the following ways:

• hg resolve [--tool TOOL] FILE...: attempt to re-merge the specified files, discarding any previous merge attempts. Re-merging is not performed for files already marked as resolved. Use --all/-a to select all unresolved files. --tool can be used to specify the merge tool used for the given files. It overrides the HGMERGE environment variable and your configuration files. Previous file contents are saved with a .orig suffix.
• hg resolve -m [FILE]: mark a file as having been resolved (e.g. after having manually fixed-up the files). The default is to mark all unresolved files.
• hg resolve -u [FILE]...: mark a file as unresolved. The default is to mark all resolved files.
• hg resolve -l: list files which had or still have conflicts. In the printed list, U = unresolved and R = resolved.

Note that Mercurial will not let you commit files with unresolved merge conflicts. You must use hg resolve -m ... before you can commit after a conflicting merge.

Returns 0 on success, 1 if any files fail a resolve attempt.

Options:

revert

hg revert [OPTION]... [-r REV] [NAME]...

With no revision specified, revert the specified files or directories to the contents they had in the parent of the working directory. This restores the contents of files to an unmodified state and unschedules adds, removes, copies, and renames. If the working directory has two parents, you must explicitly specify a revision.

Using the -r/--rev or -d/--date options, revert the given files or directories to their states as of a specific revision. Because revert does not change the working directory parents, this will cause these files to appear modified. This can be helpful to "back out" some or all of an earlier change. See hg backout for a related method.

Modified files are saved with a .orig suffix before reverting. To disable these backups, use --no-backup.

See hg help dates for a list of formats valid for -d/--date.

Returns 0 on success.

Options:

rollback

hg rollback

This command should be used with care. There is only one level of rollback, and there is no way to undo a rollback. It will also restore the dirstate at the time of the last transaction, losing any dirstate changes since that time. This command does not alter the working directory.

Transactions are used to encapsulate the effects of all commands that create new changesets or propagate existing changesets into a repository. For example, the following commands are transactional, and their effects can be rolled back:

• commit
• import
• pull
• push (with this repository as the destination)
• unbundle

To avoid permanent data loss, rollback will refuse to rollback a commit transaction if it isn't checked out. Use --force to override this protection.

This command is not intended for use on public repositories. Once changes are visible for pull by other users, rolling a transaction back locally is ineffective (someone else may already have pulled the changes). Furthermore, a race is possible with readers of the repository; for example an in-progress pull from the repository may fail if a rollback is performed.

Returns 0 on success, 1 if no rollback data is available.

Options:

root

hg root

Print the root directory of the current repository.

Returns 0 on success.

serve

hg serve [OPTION]...

Start a local HTTP repository browser and pull server. You can use this for ad-hoc sharing and browsing of repositories. It is recommended to use a real web server to serve a repository for longer periods of time.

Please note that the server does not implement access control. This means that, by default, anybody can read from the server and nobody can write to it by default. Set the web.allow_push option to * to allow everybody to push to the server. You should use a real web server if you need to authenticate users.

By default, the server logs accesses to stdout and errors to stderr. Use the -A/--accesslog and -E/--errorlog options to log to files.

To have the server choose a free port number to listen on, specify a port number of 0; in this case, the server will print the port number it uses.

Returns 0 on success.

Options:

showconfig

hg showconfig [-u] [NAME]...

With no arguments, print names and values of all config items.

With one argument of the form section.name, print just the value of that config item.

With multiple arguments, print names and values of all config items with matching section names.

With --debug, the source (filename and line number) is printed for each config item.

Returns 0 on success.

Options:

status

hg status [OPTION]... [FILE]...

Show status of files in the repository. If names are given, only files that match are shown. Files that are clean or ignored or the source of a copy/move operation, are not listed unless -c/--clean, -i/--ignored, -C/--copies or -A/--all are given. Unless options described with "show only ..." are given, the options -mardu are used.

Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested with -u/--unknown or -i/--ignored.

If one revision is given, it is used as the base revision. If two revisions are given, the differences between them are shown. The --change option can also be used as a shortcut to list the changed files of a revision from its first parent.

The codes used to show the status of files are:

M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
  = origin of the previous file listed as A (added)

Returns 0 on success.

Options:

summary

hg summary [--remote]

This generates a brief summary of the working directory state, including parents, branch, commit status, and available updates.

With the --remote option, this will check the default paths for incoming and outgoing changes. This can be time-consuming.

Returns 0 on success.

Options:

tag

hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...

Name a particular revision using <name>.

Tags are used to name particular revisions of the repository and are very useful to compare different revisions, to go back to significant earlier versions or to mark branch points as releases, etc. Changing an existing tag is normally disallowed; use -f/--force to override.

If no revision is given, the parent of the working directory is used, or tip if no revision is checked out.

To facilitate version control, distribution, and merging of tags, they are stored as a file named ".hgtags" which is managed similarly to other project files and can be hand-edited if necessary. This also means that tagging creates a new commit. The file ".hg/localtags" is used for local tags (not shared among repositories).

Tag commits are usually made at the head of a branch. If the parent of the working directory is not a branch head, hg tag aborts; use -f/--force to force the tag commit to be based on a non-head changeset.

See hg help dates for a list of formats valid for -d/--date.

Since tag names have priority over branch names during revision lookup, using an existing branch name as a tag name is discouraged.

Returns 0 on success.

Options:

tags

hg tags

This lists both regular and local tags. When the -v/--verbose switch is used, a third column "local" is printed for local tags.

Returns 0 on success.

tip

hg tip [-p] [-g]

The tip revision (usually just called the tip) is the changeset most recently added to the repository (and therefore the most recently changed head).

If you have just made a commit, that commit will be the tip. If you have just pulled changes from another repository, the tip of that repository becomes the current tip. The "tip" tag is special and cannot be renamed or assigned to a different changeset.

Returns 0 on success.

Options:

unbundle

hg unbundle [-u] FILE...

Apply one or more compressed changegroup files generated by the bundle command.

Returns 0 on success, 1 if an update has unresolved files.

Options:

update

hg update [-c] [-C] [-d DATE] [[-r] REV]

Update the repository's working directory to the specified changeset. If no changeset is specified, update to the tip of the current named branch and move the current bookmark (see hg help bookmarks).

If the changeset is not a descendant of the working directory's parent, the update is aborted. With the -c/--check option, the working directory is checked for uncommitted changes; if none are found, the working directory is updated to the specified changeset.

Update sets the working directory's parent revison to the specified changeset (see hg help parents).

The following rules apply when the working directory contains uncommitted changes:

1. If neither -c/--check nor -C/--clean is specified, and if the requested changeset is an ancestor or descendant of the working directory's parent, the uncommitted changes are merged into the requested changeset and the merged result is left uncommitted. If the requested changeset is not an ancestor or descendant (that is, it is on another branch), the update is aborted and the uncommitted changes are preserved.
2. With the -c/--check option, the update is aborted and the uncommitted changes are preserved.
3. With the -C/--clean option, uncommitted changes are discarded and the working directory is updated to the requested changeset.

Use null as the changeset to remove the working directory (like hg clone -U).

If you want to revert just one file to an older revision, use hg revert [-r REV] NAME.

See hg help dates for a list of formats valid for -d/--date.

Returns 0 on success, 1 if there are unresolved files.

Options:

verify

hg verify

Verify the integrity of the current repository.

This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks and indices.

Returns 0 on success, 1 if errors are encountered.

version

hg version

output version and copyright information

Available merge tools

External merge tools and their properties are configured in the merge-tools configuration section - see hgrc(5) - but they can often just be named by their executable.

A merge tool is generally usable if its executable can be found on the system and if it can handle the merge. The executable is found if it is an absolute or relative executable path or the name of an application in the executable search path. The tool is assumed to be able to handle the merge if it can handle symlinks if the file is a symlink, if it can handle binary files if the file is binary, and if a GUI is available if the tool requires a GUI.

There are some internal merge tools which can be used. The internal merge tools are:

internal:dump

Creates three versions of the files to merge, containing the contents of local, other and base. These files can then be used to perform a merge manually. If the file to be merged is named a.txt, these files will accordingly be named a.txt.local, a.txt.other and a.txt.base and they will be placed in the same directory as a.txt.

internal:fail

Rather than attempting to merge files that were modified on both branches, it marks them as unresolved. The resolve command must be used to resolve these conflicts.

internal:local

Uses the local version of files as the merged version.

internal:merge

Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there are any conflicts and leave markers in the partially merged file.

internal:other

Uses the other version of files as the merged version.

internal:prompt

Asks the user which of the local or the other version to keep as the merged version.

Internal tools are always available and do not require a GUI but will by default not handle symlinks or binary files.

Choosing a merge tool

Mercurial uses these rules when deciding which merge tool to use:

1. If a tool has been specified with the --tool option to merge or resolve, it is used. If it is the name of a tool in the merge-tools configuration, its configuration is used. Otherwise the specified tool must be executable by the shell.
2. If the HGMERGE environment variable is present, its value is used and must be executable by the shell.
3. If the filename of the file to be merged matches any of the patterns in the merge-patterns configuration section, the first usable merge tool corresponding to a matching pattern is used. Here, binary capabilities of the merge tool are not considered.
4. If ui.merge is set it will be considered next. If the value is not the name of a configured tool, the specified value is used and must be executable by the shell. Otherwise the named tool is used if it is usable.
5. If any usable merge tools are present in the merge-tools configuration section, the one with the highest priority is used.
6. If a program named hgmerge can be found on the system, it is used - but it will by default not be used for symlinks and binary files.
7. If the file to be merged is not binary and is not a symlink, then internal:merge is used.
8. The merge of the file fails and must be resolved before commit.

See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge tools.

acl

hooks for controlling repository access

This hook makes it possible to allow or deny write access to given branches and paths of a repository when receiving incoming changesets via pretxnchangegroup and pretxncommit.

The authorization is matched based on the local user name on the system where the hook runs, and not the committer of the original changeset (since the latter is merely informative).

The acl hook is best used along with a restricted shell like hgsh, preventing authenticating users from doing anything other than pushing or pulling. The hook is not safe to use if users have interactive shell access, as they can then disable the hook. Nor is it safe if remote users share an account, because then there is no way to distinguish them.

The order in which access checks are performed is:

1. Deny list for branches (section acl.deny.branches)
2. Allow list for branches (section acl.allow.branches)
3. Deny list for paths (section acl.deny)
4. Allow list for paths (section acl.allow)

The allow and deny sections take key-value pairs.

[hooks]

# Use this if you want to check access restrictions at commit time

bugzilla

hooks for integrating with the Bugzilla bug tracker

This hook extension adds comments on bugs in Bugzilla when changesets that refer to bugs by Bugzilla ID are seen. The comment is formatted using the Mercurial template mechanism.

The bug references can optionally include an update for Bugzilla of the hours spent working on the bug. Bugs can also be marked fixed.

Three basic modes of access to Bugzilla are provided:

1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
2. Check data via the Bugzilla XMLRPC interface and submit bug change via email to Bugzilla email interface. Requires Bugzilla 3.4 or later.
3. Writing directly to the Bugzilla database. Only Bugzilla installations using MySQL are supported. Requires Python MySQLdb.

Writing directly to the database is susceptible to schema changes, and relies on a Bugzilla contrib script to send out bug change notification emails. This script runs as the user running Mercurial, must be run on the host with the Bugzilla install, and requires permission to read Bugzilla configuration details and the necessary MySQL user and password to have full access rights to the Bugzilla database. For these reasons this access mode is now considered deprecated, and will not be updated for new Bugzilla versions going forward. Only adding comments is supported in this access mode.

Access via XMLRPC needs a Bugzilla username and password to be specified in the configuration. Comments are added under that username. Since the configuration must be readable by all Mercurial users, it is recommended that the rights of that user are restricted in Bugzilla to the minimum necessary to add comments. Marking bugs fixed requires Bugzilla 4.0 and later.

Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the Bugzilla email interface to submit comments to bugs. The From: address in the email is set to the email address of the Mercurial user, so the comment appears to come from the Mercurial user. In the event that the Mercurial user email is not recognised by Bugzilla as a Bugzilla user, the email associated with the Bugzilla username used to log into Bugzilla is used instead as the source of the comment. Marking bugs fixed works on all supported Bugzilla versions.

Configuration items common to all access modes:

bugzilla.version

This access type to use. Values recognised are:

xmlrpc:	Bugzilla XMLRPC interface.
xmlrpc+email:	Bugzilla XMLRPC and email interfaces.
3.0:	MySQL access, Bugzilla 3.0 and later.
2.18:	MySQL access, Bugzilla 2.18 and up to but not including 3.0.
2.16:	MySQL access, Bugzilla 2.16 and up to but not including 2.18.

bugzilla.regexp

Regular expression to match bug IDs for update in changeset commit message. It must contain one "()" named group <ids> containing the bug IDs separated by non-digit characters. It may also contain a named group <hours> with a floating-point number giving the hours worked on the bug. If no named groups are present, the first "()" group is assumed to contain the bug IDs, and work time is not updated. The default expression matches Bug 1234, Bug no. 1234, Bug number 1234, Bugs 1234,5678, Bug 1234 and 5678 and variations thereof, followed by an hours number prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.

bugzilla.fixregexp

Regular expression to match bug IDs for marking fixed in changeset commit message. This must contain a "()" named group <ids>` containing the bug IDs separated by non-digit characters. It may also contain a named group ``<hours> with a floating-point number giving the hours worked on the bug. If no named groups are present, the first "()" group is assumed to contain the bug IDs, and work time is not updated. The default expression matches Fixes 1234, Fixes bug 1234, Fixes bugs 1234,5678, Fixes 1234 and 5678 and variations thereof, followed by an hours number prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.

bugzilla.fixstatus

The status to set a bug to when marking fixed. Default RESOLVED.

bugzilla.fixresolution

The resolution to set a bug to when marking fixed. Default FIXED.

bugzilla.style

The style file to use when formatting comments.

bugzilla.template

Template to use when formatting comments. Overrides style if specified. In addition to the usual Mercurial keywords, the extension specifies:

{bug}:	The Bugzilla bug ID.
{root}:	The full pathname of the Mercurial repository.
{webroot}:	Stripped pathname of the Mercurial repository.
{hgweb}:	Base URL for browsing Mercurial repositories.

Default changeset {node|short} in repo {root} refers to bug {bug}.\ndetails:\n\t{desc|tabindent}

bugzilla.strip

The number of path separator characters to strip from the front of the Mercurial repository path ({root} in templates) to produce {webroot}. For example, a repository with {root} /var/local/my-project with a strip of 2 gives a value for {webroot} of my-project. Default 0.

web.baseurl

Base URL for browsing Mercurial repositories. Referenced from templates as {hgweb}.

Configuration items common to XMLRPC+email and MySQL access modes:

bugzilla.usermap

Path of file containing Mercurial committer email to Bugzilla user email mappings. If specified, the file should contain one mapping per line:

committer = Bugzilla user

See also the [usermap] section.

The [usermap] section is used to specify mappings of Mercurial committer email to Bugzilla user email. See also bugzilla.usermap. Contains entries of the form committer = Bugzilla user.

XMLRPC access mode configuration:

bugzilla.bzurl

The base URL for the Bugzilla installation. Default http://localhost/bugzilla.

bugzilla.user

The username to use to log into Bugzilla via XMLRPC. Default bugs.

bugzilla.password

The password for Bugzilla login.

XMLRPC+email access mode uses the XMLRPC access mode configuration items, and also:

bugzilla.bzemail

The Bugzilla email address.

In addition, the Mercurial email settings must be configured. See the documentation in hgrc(5), sections [email] and [smtp].

MySQL access mode configuration:

bugzilla.host

Hostname of the MySQL server holding the Bugzilla database. Default localhost.

bugzilla.db

Name of the Bugzilla database in MySQL. Default bugs.

bugzilla.user

Username to use to access MySQL server. Default bugs.

bugzilla.password

Password to use to access MySQL server.

bugzilla.timeout

Database connection timeout (seconds). Default 5.

bugzilla.bzuser

Fallback Bugzilla user name to record comments with, if changeset committer cannot be found as a Bugzilla user.

bugzilla.bzdir

Bugzilla install directory. Used by default notify. Default /var/www/html/bugzilla.

bugzilla.notify

The command to run to get Bugzilla to send bug change notification emails. Substitutes from a map with 3 keys, bzdir, id (bug id) and user (committer bugzilla email). Default depends on version; from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbugmail.pl %(id)s %(user)s".

color

colorize output from some commands

This extension modifies the status and resolve commands to add color to their output to reflect file status, the qseries command to add color to reflect patch status (applied, unapplied, missing), and to diff-related commands to highlight additions, removals, diff headers, and trailing whitespace.

Other effects in addition to color, like bold and underlined text, are also available. By default, the terminfo database is used to find the terminal codes used to change color and effect. If terminfo is not available, then effects are rendered with the ECMA-48 SGR control function (aka ANSI escape codes).

Default effects may be overridden from your configuration file:

[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold

# 'none' turns off all effects
status.clean = none
status.copied = none

qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold

diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.trailingwhitespace = bold red_background

resolve.unresolved = red bold
resolve.resolved = green bold

bookmarks.current = green

branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none

tags.normal = green
tags.local = black bold

The available effects in terminfo mode are 'blink', 'bold', 'dim', 'inverse', 'invisible', 'italic', 'standout', and 'underline'; in ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and 'underline'. How each is rendered depends on the terminal emulator. Some may not be available for a given terminal type, and will be silently ignored.

Note that on some systems, terminfo mode may cause problems when using color with the pager extension and less -R. less with the -R option will only display ECMA-48 color codes, and terminfo mode may sometimes emit codes that less doesn't understand. You can work around this by either using ansi mode (or auto mode), or by using less -r (which will pass through all terminal control codes, not just color control codes).

Because there are only eight standard colors, this module allows you to define color names for other color slots which might be available for your terminal type, assuming terminfo mode. For instance:

color.brightblue = 12
color.pink = 207
color.orange = 202

to set 'brightblue' to color slot 12 (useful for 16 color terminals that have brighter colors defined in the upper eight) and, 'pink' and 'orange' to colors in 256-color xterm's default color cube. These defined colors may then be used as any of the pre-defined eight, including appending '_background' to set the background to that color.

By default, the color extension will use ANSI mode (or win32 mode on Windows) if it detects a terminal. To override auto mode (to enable terminfo mode, for example), set the following configuration option:

[color]
mode = terminfo

Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will disable color.

eol

automatically manage newlines in repository files

This extension allows you to manage the type of line endings (CRLF or LF) that are used in the repository and in the local working directory. That way you can get CRLF line endings on Windows and LF on Unix/Mac, thereby letting everybody use their OS native line endings.

The extension reads its configuration from a versioned .hgeol configuration file found in the root of the working copy. The .hgeol file use the same syntax as all other Mercurial configuration files. It uses two sections, [patterns] and [repository].

The [patterns] section specifies how line endings should be converted between the working copy and the repository. The format is specified by a file pattern. The first match is used, so put more specific patterns first. The available line endings are LF, CRLF, and BIN.

Files with the declared format of CRLF or LF are always checked out and stored in the repository in that format and files declared to be binary (BIN) are left unchanged. Additionally, native is an alias for checking out in the platform's default line ending: LF on Unix (including Mac OS X) and CRLF on Windows. Note that BIN (do nothing to line endings) is Mercurial's default behaviour; it is only needed if you need to override a later, more general pattern.

The optional [repository] section specifies the line endings to use for files stored in the repository. It has a single setting, native, which determines the storage line endings for files declared as native in the [patterns] section. It can be set to LF or CRLF. The default is LF. For example, this means that on Windows, files configured as native (CRLF by default) will be converted to LF when stored in the repository. Files declared as LF, CRLF, or BIN in the [patterns] section are always stored as-is in the repository.

Example versioned .hgeol file:

[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN

[repository]
native = LF

The extension uses an optional [eol] section read from both the normal Mercurial configuration files and the .hgeol file, with the latter overriding the former. You can use that section to control the overall behavior. There are three settings:

• eol.native (default os.linesep) can be set to LF or CRLF to override the default interpretation of native for checkout. This can be used with hg archive on Unix, say, to generate an archive where files have line endings for Windows.
• eol.only-consistent (default True) can be set to False to make the extension convert files with inconsistent EOLs. Inconsistent means that there is both CRLF and LF present in the file. Such files are normally not touched under the assumption that they have mixed EOLs on purpose.
• eol.fix-trailing-newline (default False) can be set to True to ensure that converted files end with a EOL character (either \n or \r\n as per the configured patterns).

The extension provides cleverencode: and cleverdecode: filters like the deprecated win32text extension does. This means that you can disable win32text and enable eol and your filters will still work. You only need to these filters until you have prepared a .hgeol file.

The win32text.forbid* hooks provided by the win32text extension have been unified into a single hook named eol.checkheadshook. The hook will lookup the expected line endings from the .hgeol file, which means you must migrate to a .hgeol file first before using the hook. eol.checkheadshook only checks heads, intermediate invalid revisions will be pushed. To forbid them completely, use the eol.checkallhook hook. These hooks are best used as pretxnchangegroup hooks.

See hg help patterns for more information about the glob patterns used.

extdiff

command to allow external programs to compare revisions

The extdiff Mercurial extension allows you to use external programs to compare revisions, or revision with working directory. The external diff programs are called with a configurable set of options and two non-option arguments: paths to directories containing snapshots of files to compare.

The extdiff extension also allows you to configure new diff commands, so you do not need to type hg extdiff -p kdiff3 always.

[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5

# add new command called vdiff, runs kdiff3
vdiff = kdiff3

# add new command called meld, runs meld (no need to name twice)
meld =

# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next" \
          "+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"

Tool arguments can include variables that are expanded at runtime:

$parent1, $plabel1 - filename, descriptive label of first parent
$child,   $clabel  - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root              - repository root
$parent is an alias for $parent1.

The extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff tool arguments, when none are specified in [extdiff].

[extdiff]
kdiff3 =

[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child

You can use -I/-X and list of file or directory names like normal hg diff command. The extdiff extension makes snapshots of only needed files, so running the external diff program will actually be pretty fast (at least faster than having to compare the entire tree).

hg extdiff [OPT]... [FILE]...

factotum

http authentication with factotum

This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access. Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully supported. If no prefix is specified, a value of "*" will be assumed.

By default, keys are specified as:

proto=pass service=hg prefix=<prefix> user=<username> !password=<password>

If the factotum extension is unable to read the required key, one will be requested interactively.

A configuration section is available to customize runtime behavior. By default, these entries are:

[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg

The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service. Lastly, the service entry controls the service name used when reading keys.

This is meant to be run as a changegroup or incoming hook. To configure it, set the following options in your hgrc:

[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}\n{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)
# You can use mailto: URLs to send by email, eg
# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False
# number of slashes to strip for url paths
#strip = 0

[hooks]
# one of these:
changegroup.cia = python:hgcia.hook
#incoming.cia = python:hgcia.hook

[web]
# If you want hyperlinks (optional)
baseurl = http://server/path/to/repo

hgk

browse the repository in a graphical way

The hgk extension allows browsing the history of a repository in a graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not distributed with Mercurial.)

hgk consists of two parts: a Tcl script that does the displaying and querying of information, and an extension to Mercurial named hgk.py, which provides hooks for hgk to get information. hgk can be found in the contrib directory, and the extension is shipped in the hgext repository, and needs to be enabled.

The hg view command will launch the hgk Tcl script. For this command to work, hgk must be in your search path. Alternately, you can specify the path to hgk in your configuration file:

[hgk]
path=/location/of/hgk

hgk can make use of the extdiff extension to visualize revisions. Assuming you had already configured extdiff vdiff command, just add:

[hgk]
vdiff=vdiff

Revisions context menu will now display additional entries to fire vdiff on hovered and selected revisions.

hg view [-l LIMIT] [REVRANGE]

highlight

syntax highlighting for hgweb (requires Pygments)

It depends on the Pygments syntax highlighting library: http://pygments.org/

There is a single configuration option:

[web]
pygments_style = <style>

The default is 'colorful'.

inotify

accelerate status report using Linux's inotify service

hg inserve [OPTION]...

interhg

expand expressions into changelog and summaries

This extension allows the use of a special syntax in summaries, which will be automatically expanded into links or any other arbitrary expression, much like InterWiki does.

A few example patterns (link to bug tracking, etc.) that may be used in your hgrc:

[interhg]
issues = s!issue(\d+)!<a href="http://bts/issue\1">issue\1</a>!
bugzilla = s!((?:bug|b=|(?=#?\d{4,}))(?:\s*#?)(\d+))!<a..=\2">\1</a>!i
boldify = s!(^|\s)#(\d+)\b! <b>#\2</b>!

keyword

expand keywords in tracked files

This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked text files selected by your configuration.

Keywords are only expanded in local repositories and not stored in the change history. The mechanism can be regarded as a convenience for the current user or for archive distribution.

Keywords expand to the changeset data pertaining to the latest change relative to the working directory parent of each file.

Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections of hgrc files.

Example:

[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x*    = ignore

[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True

For [keywordmaps] template mapping and expansion demonstration and control run hg kwdemo. See hg help templates for a list of available templates and filters.

Three additional date template filters are provided:

The default template mappings (view with hg kwdemo -d) can be replaced with customized keywords and templates. Again, run hg kwdemo to control the results of your configuration changes.

Before changing/disabling active keywords, you must run hg kwshrink to avoid storing expanded keywords in the change history.

To force expansion after enabling it, or a configuration change, run hg kwexpand.

Expansions spanning more than one line and incremental expansions, like CVS' $Log$, are not supported. A keyword template map "Log = {desc}" expands to the first line of the changeset description.

hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...

hg kwexpand [OPTION]... [FILE]...

hg kwfiles [OPTION]... [FILE]...

K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)

hg kwshrink [OPTION]... [FILE]...

largefiles

track large binary files

Large binary files tend to be not very compressible, not very diffable, and not at all mergeable. Such files are not handled efficiently by Mercurial's storage format (revlog), which is based on compressed binary deltas; storing large binary files as regular Mercurial files wastes bandwidth and disk space and increases Mercurial's memory usage. The largefiles extension addresses these problems by adding a centralized client-server layer on top of Mercurial: largefiles live in a central store out on the network somewhere, and you only fetch the revisions that you need when you need them.

largefiles works by maintaining a "standin file" in .hglf/ for each largefile. The standins are small (41 bytes: an SHA-1 hash plus newline) and are tracked by Mercurial. Largefile revisions are identified by the SHA-1 hash of their contents, which is written to the standin. largefiles uses that revision ID to get/put largefile revisions from/to the central store. This saves both disk space and bandwidth, since you don't need to retrieve all historical revisions of large files when you clone or pull.

To start a new repository or add new large binary files, just add --large to your hg add command. For example:

$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m 'add randomdata as a largefile'

When you push a changeset that adds/modifies largefiles to a remote repository, its largefile revisions will be uploaded along with it. Note that the remote Mercurial must also have the largefiles extension enabled for this to work.

When you pull a changeset that affects largefiles from a remote repository, Mercurial behaves as normal. However, when you update to such a revision, any largefiles needed by that revision are downloaded and cached (if they have never been downloaded before). This means that network access may be required to update to changesets you have not previously updated to.

If you already have large files tracked by Mercurial without the largefiles extension, you will need to convert your repository in order to benefit from largefiles. This is done with the hg lfconvert command:

$ hg lfconvert --size 10 oldrepo newrepo

In repositories that already have largefiles in them, any new file over 10MB will automatically be added as a largefile. To change this threshold, set largefiles.minsize in your Mercurial config file to the minimum size in megabytes to track as a largefile, or use the --lfsize option to the add command (also in megabytes):

[largefiles]
minsize = 2

$ hg add --lfsize 2

The largefiles.patterns config option allows you to specify a list of filename patterns (see hg help patterns) that should always be tracked as largefiles:

[largefiles]
patterns =
  *.jpg
  re:.*\.(png|bmp)$
  library.zip
  content/audio/*

Files that match one of these patterns will be added as largefiles regardless of their size.

The largefiles.minsize and largefiles.patterns config options will be ignored for any repositories not already containing a largefile. To add the first largefile to a repository, you must explicitly do so with the --large flag passed to the hg add command.

hg lfconvert SOURCE DEST [FILE ...]

mq

manage a stack of patches

This extension lets you work with a stack of patches in a Mercurial repository. It manages two stacks of patches - all known patches, and applied patches (subset of known patches).

Known patches are represented as patch files in the .hg/patches directory. Applied patches are both patch files and changesets.

Common tasks (use hg help command for more details):

create new patch                          qnew
import existing patch                     qimport

print patch series                        qseries
print applied patches                     qapplied

add known patch to applied stack          qpush
remove patch from applied stack           qpop
refresh contents of top applied patch     qrefresh

By default, mq will automatically use git patches when required to avoid losing file mode changes, copy records, binary files or empty files creations or deletions. This behaviour can be configured with:

[mq]
git = auto/keep/yes/no

If set to 'keep', mq will obey the [diff] section configuration while preserving existing git patches upon qrefresh. If set to 'yes' or 'no', mq will override the [diff] section and always generate git or regular patches, possibly losing data in the second case.

It may be desirable for mq changesets to be kept in the secret phase (see hg help phases), which can be enabled with the following setting:

[mq]
secret = True

You will by default be managing a patch queue named "patches". You can create other, independent patch queues with the hg qqueue command.

hg qapplied [-1] [-s] [PATCH]

hg qclone [OPTION]... SOURCE [DEST]

hg qcommit [OPTION]... [FILE]...

hg qdelete [-k] [PATCH]...

hg qdiff [OPTION]... [FILE]...

hg qfinish [-a] [REV]...

hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...

hg qgoto [OPTION]... PATCH

hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]

hg qguard other.patch -- +2.6.17 -stable

hg qheader [PATCH]

hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... FILE...

hg qimport -e existing-patch -n new-name

hg qinit [-c]

hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...

hg qnext [-s]

hg qpop [-a] [-f] [PATCH | INDEX]

hg qprev [-s]

hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]

hg qqueue [OPTION] [QUEUE]

hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...

hg qrename PATCH1 [PATCH2]

hg qrestore [-d] [-u] REV

hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]

hg qselect [OPTION]... [GUARD]...

qguard foo.patch -- -stable    (negative guard)
qguard bar.patch    +stable    (positive guard)
qselect stable

hg qseries [-ms]

hg qtop [-s]

hg qunapplied [-1] [-s] [PATCH]

hg strip [-k] [-f] [-n] REV...

notify

hooks for sending email push notifications

This extension let you run hooks sending email notifications when changesets are being pushed, from the sending or receiving side.

First, enable the extension as explained in hg help extensions, and register the hook you want to run. incoming and changegroup hooks are run by the changesets receiver while the outgoing one is for the sender:

[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook

# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook

Now the hooks are running, subscribers must be assigned to repositories. Use the [usersubs] section to map repositories to a given email or the [reposubs] section to map emails to a single repository:

[usersubs]
# key is subscriber email, value is a comma-separated list of glob
# patterns
user@host = pattern

[reposubs]
# key is glob pattern, value is a comma-separated list of subscriber
# emails
pattern = user@host

Glob patterns are matched against absolute path to repository root. The subscriptions can be defined in their own file and referenced with:

[notify]
config = /path/to/subscriptionsfile

Alternatively, they can be added to Mercurial configuration files by setting the previous entry to an empty value.

At this point, notifications should be generated but will not be sent until you set the notify.test entry to False.

Notifications content can be tweaked with the following configuration entries:

notify.test

If True, print messages to stdout instead of sending them. Default: True.

notify.sources

Space separated list of change sources. Notifications are sent only if it includes the incoming or outgoing changes source. Incoming sources can be serve for changes coming from http or ssh, pull for pulled changes, unbundle for changes added by hg unbundle or push for changes being pushed locally. Outgoing sources are the same except for unbundle which is replaced by bundle. Default: serve.

notify.strip

Number of leading slashes to strip from url paths. By default, notifications references repositories with their absolute path. notify.strip let you turn them into relative paths. For example, notify.strip=3 will change /long/path/repository into repository. Default: 0.

notify.domain

If subscribers emails or the from email have no domain set, complete them with this value.

notify.style

Style file to use when formatting emails.

notify.template

Template to use when formatting emails.

notify.incoming

Template to use when run as incoming hook, override notify.template.

notify.outgoing

Template to use when run as outgoing hook, override notify.template.

notify.changegroup

Template to use when running as changegroup hook, override notify.template.

notify.maxdiff

Maximum number of diff lines to include in notification email. Set to 0 to disable the diff, -1 to include all of it. Default: 300.

notify.maxsubject

Maximum number of characters in emails subject line. Default: 67.

notify.diffstat

Set to True to include a diffstat before diff content. Default: True.

notify.merge

If True, send notifications for merge changesets. Default: True.

notify.mbox

If set, append mails to this mbox file instead of sending. Default: None.

notify.fromauthor

If set, use the first committer of the changegroup for the "From" field of the notification mail. If not set, take the user from the pushing repo. Default: False.

If set, the following entries will also be used to customize the notifications:

email.from

Email From address to use if none can be found in generated email content.

web.baseurl

Root repository browsing URL to combine with repository paths when making references. See also notify.strip.

pager

browse command output with an external pager

To set the pager that should be used, set the application variable:

[pager]
pager = less -FRSX

If no pager is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager is used.

You can disable the pager for certain commands by adding them to the pager.ignore list:

[pager]
ignore = version, help, update

You can also enable the pager only for certain commands using pager.attend. Below is the default list of commands to be paged:

[pager]
attend = annotate, cat, diff, export, glog, log, qdiff

Setting pager.attend to an empty value will cause all commands to be paged.

If pager.attend is present, pager.ignore will be ignored.

To ignore global commands like hg version or hg help, you have to specify them in your user configuration file.

The --pager=... option can also be used to control when the pager is used. Use a boolean value like yes, no, on, off, or use auto for normal behavior.

patchbomb

command to send changesets as (a series of) patch emails

The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole.

Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The message contains two or three body parts:

• The changeset description.
• [Optional] The result of running diffstat on the patch.
• The patch itself, as generated by hg export.

Each message refers to the first in the series using the In-Reply-To and References headers, so they will show up as a sequence in threaded mail and news readers, and in mail archives.

To configure other defaults, add a section like this to your configuration file:

[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...

Use [patchbomb] as configuration section name if you need to override global [email] address settings.

Then you can use the hg email command to mail a series of changesets as a patchbomb.

You can also either configure the method option in the email section to be a sendmail compatible mailer or fill out the [smtp] section so that the patchbomb extension can automatically send patchbombs directly from the commandline. See the [email] and [smtp] sections in hgrc(5) for details.

hg email [OPTION]... [DEST]...
