    enable debugging output

--debugger
    start debugger

--encoding
    set the charset encoding (default: ascii)

--encodingmode
    set the charset encoding mode (default: strict)

--traceback
    always print a traceback on exception

COMMANDS

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.

    An example showing how new (unknown) files are added automatically by hg add:

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

    options:

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-n, --dry-run
    do not perform actions, just print output

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 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.

    options:

-s, --similarity
    guess renamed files by similarity (0<=s<=100)

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-n, --dry-run
    do not perform actions, just print output

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.

    options:

-r, --rev
    annotate the specified revision

--follow
    follow copies/renames and list the filename (DEPRECATED)

--no-follow
    don't follow copies and renames

-a, --text
    treat all files as text

-u, --user
    list the author (long with -v)

-f, --file
    list the filename

-d, --date
    list the date (short with -q)

-n, --number
    list the revision number (default)

-c, --changeset
    list the changeset

-l, --line-number
    show line number at the first appearance

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

    aliases: blame

archive [OPTION]... DEST

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

    To specify the type of archive to create, use -t/--type. Valid types are:

files

    a directory full of files (default)

tar

    tar archive, uncompressed

tbz2

    tar archive, compressed using bzip2

tgz

    tar archive, compressed using gzip

uzip

    zip archive, uncompressed

zip

    zip archive, compressed using deflate

    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.

    options:

--no-decode
    do not pass files through decoders

-p, --prefix
    directory prefix for files in archive

-r, --rev
    revision to distribute

-t, --type
    type of distribution to create

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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

    Commit the backed out changes as a new changeset. The new changeset is a child of the backed out changeset.

    If you backout a changeset other than the tip, a new head is created. This head will be the new tip and you should merge this backout changeset with another head.

    The --merge option remembers the parent of the working directory before starting the backout, then merges the new head with that changeset afterwards. This saves you from doing the merge by hand. The result of this merge is not committed, as with a normal merge.

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

    options:

--merge
    merge with old dirstate parent after backout

--parent
    parent to choose when backing out merge

-r, --rev
    revision to backout

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-m, --message
    use <text> as commit message

-l, --logfile
    read commit message from <file>

-d, --date
    record datecode as commit date

-u, --user
    record the specified user as committer

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.

    options:

-r, --reset
    reset bisect state

-g, --good
    mark changeset good

-b, --bad
    mark changeset bad

-s, --skip
    skip testing changeset

-c, --command
    use command to check changeset state

-U, --noupdate
    do not update to target

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.

    options:

-f, --force
    set branch name even if it shadows an existing branch

-C, --clean
    reset branch name to parent branch name

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.

    options:

-a, --active
    show only branches that have unmerged heads

-c, --closed
    show normal and closed branches

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.

    options:

-f, --force
    run even when the destination is unrelated

-r, --rev
    a changeset intended to be added to the destination

-b, --branch
    a specific branch you would like to bundle

--base
    a base changeset assumed to be available at the destination

-a, --all
    bundle all changesets in the repository

-t, --type
    bundle compression type to use (default: bzip2)

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

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:

%s

    basename of file being printed

%d

    dirname of file being printed, or '.' if in repository root

%p

    root-relative path name of file being printed

    options:

-o, --output
    print output to file with formatted name

-r, --rev
    print the given revision

--decode
    apply any matching decode filter

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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

    See 'hg help urls' for valid source format details.

    It is possible to specify an ssh:// URL as the destination, but no Please see 'hg help urls' for important details about ssh:// URLs.

    A set of changesets (tags, or branch names) to pull may be specified by listing each changeset (tag, or branch name) with -r/--rev. If -r/--rev is used, the cloned repository will contain only a subset of the changesets of the source repository. Only the set of changesets defined by all -r/--rev options (including all their ancestors) will be pulled into the destination repository. No subsequent changesets (including subsequent tags) will be present in the destination.

    Using -r/--rev (or 'clone src#rev dest') implies --pull, even for local source repositories.

    For efficiency, hardlinks are used for cloning whenever the source and destination are on the same filesystem (note this applies only to the repository data, not to the working directory). Some filesystems, such as AFS, implement hardlinking incorrectly, but do not report errors. In these cases, use the --pull option to avoid hardlinking.

    In some cases, you can clone repositories and the working directory using full hardlinks with

    $ cp -al REPO REPOCLONE

    This is the fastest way to clone, but it is not always safe. The operation is not atomic (making sure REPO is not modified during the operation is up to you) and you have to make sure your editor breaks hardlinks (Emacs and most Linux Kernel tools do so). Also, this is not compatible with certain extensions that place their metadata under the .hg directory, such as mq.

    Mercurial will update the working directory to the first applicable revision from this list:

a.  null if -U or the source repository has no changesets

b.  if -u . and the source repository is local, the first parent of the source repository's working directory

c.  the changeset specified with -u (if a branch name, this means the latest head of that branch)

d.  the changeset specified with -r

e.  the tipmost head specified with -b

f.  the tipmost head specified with the url#branch source syntax

g.  the tipmost head of the default branch

h.  tip

    options:

-U, --noupdate
    the clone will include an empty working copy (only a repository)

-u, --updaterev
    revision, tag or branch to check out

-r, --rev
    include the specified changeset

-b, --branch
    clone only the specified branch

--pull
    use pull protocol to copy metadata

--uncompressed
    use uncompressed transfer (fast over LAN)

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

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

    Commit changes to the given files into the repository. Unlike a centralized RCS, 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, the configured editor is started to prompt you for a message.

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

    options:

-A, --addremove
    mark new/missing files as added/removed before committing

--close-branch
    mark a branch as closed, hiding it from the branch list

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-m, --message
    use <text> as commit message

-l, --logfile
    read commit message from <file>

-d, --date
    record datecode as commit date

-u, --user
    record the specified user as committer

    aliases: ci

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.

    options:

-A, --after
    record a copy that has already occurred

-f, --force
    forcibly copy over an existing managed file

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-n, --dry-run
    do not perform actions, just print output

    aliases: cp

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.

    NOTE: diff may generate unexpected results for merges, as it will default to comparing against the working directory's first parent changeset if no revisions are specified.

    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'.

    options:

-r, --rev
    revision

-c, --change
    change made by revision

-a, --text
    treat all files as text

-g, --git
    use git extended diff format

--nodates
    omit dates from diff headers

-p, --show-function
    show which function each change is in

--reverse
    produce a diff that undoes the changes

-w, --ignore-all-space
    ignore white space when comparing lines

-b, --ignore-space-change
    ignore changes in the amount of white space

-B, --ignore-blank-lines
    ignore changes whose lines are all blank

-U, --unified
    number of lines of context to show

--stat
    output diffstat-style summary of changes

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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.

    NOTE: export may generate unexpected diff output for merge changesets, as it will compare the merge changeset against its first parent only.

    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:

%%

    literal "%" character

%H

    changeset hash (40 bytes of hexadecimal)

%N

    number of patches being generated

%R

    changeset revision number

%b

    basename of the exporting repository

%h

    short-form changeset hash (12 bytes of hexadecimal)

%n

    zero-padded sequence number, starting at 1

%r

    zero-padded changeset revision number

    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.

    options:

-o, --output
    print output to file with formatted name

--switch-parent
    diff against the second parent

-r, --rev
    revisions to export

-a, --text
    treat all files as text

-g, --git
    use git extended diff format

--nodates
    omit dates from diff headers

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.

    options:

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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.

    options:

-0, --print0
    end fields with NUL

--all
    print all revisions that match

-f, --follow
    follow changeset history, or file history across copies and renames

-i, --ignore-case
    ignore case when matching

-l, --files-with-matches
    print only filenames and revisions that match

-n, --line-number
    print matching line numbers

-r, --rev
    only search files changed within revision range

-u, --user
    list the author (long with -v)

-d, --date
    list the date (short with -q)

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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.

    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.

    options:

-r, --rev
    show only heads which are descendants of REV

-t, --topo
    show topological heads only

-a, --active
    show active branchheads only [DEPRECATED]

-c, --closed
    show normal and closed branch heads

--style
    display using template map file

--template
    display with template

help [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.

identify [-nibt] [-r REV] [SOURCE]

    With no revision, 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.

    This summary identifies the repository state using one or two parent hash identifiers, followed by a "+" if there are uncommitted changes in the working directory, a list of tags for this revision and a branch name for non-default branches.

    options:

-r, --rev
    identify the specified revision

-n, --num
    show local revision number

-i, --id
    show global revision id

-b, --branch
    show branch

-t, --tags
    show tags

    aliases: id

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.

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

    options:

-p, --strip
    directory strip option for patch. This has the same meaning as the corresponding patch option (default: 1)

-b, --base
    base path

-f, --force
    skip check for outstanding uncommitted changes

--no-commit
    don't commit, just update the working directory

--exact
    apply patch to the nodes from which it was generated

--import-branch
    use any branch information in patch (implied by --exact)

-m, --message
    use <text> as commit message

-l, --logfile
    read commit message from <file>

-d, --date
    record datecode as commit date

-u, --user
    record the specified user as committer

-s, --similarity
    guess renamed files by similarity (0<=s<=100)

    aliases: patch

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.

    options:

-f, --force
    run even if remote repository is unrelated

-n, --newest-first
    show newest record first

--bundle
    file to store the bundles into

-r, --rev
    a remote changeset intended to be added

-b, --branch
    a specific branch you would like to pull

-p, --patch
    show patch

-g, --git
    use git extended diff format

-l, --limit
    limit number of changes displayed

-M, --no-merges
    do not show merges

--style
    display using template map file

--template
    display with template

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

    aliases: in

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.

    options:

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

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.

    options:

-r, --rev
    search the repository as it is in REV

-0, --print0
    end filenames with NUL, for use with xargs

-f, --fullpath
    print complete paths from the filesystem root

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

log [OPTION]... [FILE]

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

    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. --follow-first only follows the first parent of merge revisions.

    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.

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

    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.

    NOTE: log -p/--patch may generate unexpected diff output for merge changesets, as it will only compare the merge changeset against its first parent. Also, only files different from BOTH parents will appear in files:.

    options:

-f, --follow
    follow changeset history, or file history across copies and renames

--follow-first
    only follow the first parent of merge changesets

-d, --date
    show revisions matching date spec

-C, --copies
    show copied files

-k, --keyword
    do case-insensitive search for a keyword

-r, --rev
    show the specified revision or range

--removed
    include revisions where files were removed

-m, --only-merges
    show only merges

-u, --user
    revisions committed by user

-b, --only-branch
    show only changesets within the given named branch

-P, --prune
    do not display revision or any of its ancestors

-p, --patch
    show patch

-g, --git
    use git extended diff format

-l, --limit
    limit number of changes displayed

-M, --no-merges
    do not show merges

--style
    display using template map file

--template
    display with template

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

    aliases: history

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.

    options:

-r, --rev
    revision to display

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.

    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.

    options:

-f, --force
    force a merge with outstanding changes

-r, --rev
    revision to merge

-P, --preview
    review revisions to merge (no merge is performed)

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.

    options:

-f, --force
    run even when the destination is unrelated

-r, --rev
    a changeset intended to be included in the destination

-n, --newest-first
    show newest record first

-b, --branch
    a specific branch you would like to push

-p, --patch
    show patch

-g, --git
    use git extended diff format

-l, --limit
    limit number of changes displayed

-M, --no-merges
    do not show merges

--style
    display using template map file

--template
    display with template

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

    aliases: out

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.

    options:

-r, --rev
    show parents of the specified revision

--style
    display using template map file

--template
    display with template

paths [NAME]

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

    Path names are defined in the [paths] section of /etc/mercurial/hgrc and $HOME/.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.

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 added those changes to the repository, you should use 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.

    options:

-u, --update
    update to new branch head if changesets were pulled

-f, --force
    run even when remote repository is unrelated

-r, --rev
    a remote changeset intended to be added

-b, --branch
    a specific branch you would like to pull

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

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 -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.

    options:

-f, --force
    force push

-r, --rev
    a changeset intended to be included in the destination

-b, --branch
    a specific branch you would like to push

-e, --ssh
    specify ssh command to use

--remotecmd
    specify hg command to run on the remote side

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.

remove [OPTION]... FILE...

    Schedule the indicated files for removal from the repository.

    This only removes files from the current branch, not from the entire project history. -A/--after can be used to remove only files that have already been deleted, -f/--force can be used to force deletion, and -Af can be used to remove files from the next revision without deleting them from the working directory.

    The following table details the behavior of remove for different file states (columns) and option combinations (rows). The file states are Added [A], Clean [C], Modified [M] and Missing [!] (as reported by hg status). The actions are Warn, Remove (from branch) and Delete (from disk):

           A  C  M  !
    none   W  RD W  R
    -f     R  RD RD R
    -A     W  W  W  R
    -Af    R  R  R  R

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

    options:

-A, --after
    record delete for missing files

-f, --force
    remove (and delete) file even if added or modified

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

    aliases: rm

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.

    options:

-A, --after
    record a rename that has already occurred

-f, --force
    forcibly copy over an existing managed file

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-n, --dry-run
    do not perform actions, just print output

    aliases: mv

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

    This command includes several actions that are often useful while performing a merge, after running merge but before running commit. (It is only meaningful if your working directory has two parents.) It is most relevant for merges with unresolved conflicts, which are typically a result of non-interactive merging with internal:merge or a command-line merge tool like diff3.

    The available actions are:

1.  list files that were merged with conflicts (U, for unresolved) and without conflicts (R, for resolved): hg resolve -l (this is like status for merges)

2.  record that you have resolved conflicts in certain files: hg resolve -m [file ...] (default: mark all unresolved files)

3.  forget that you have resolved conflicts in certain files: hg resolve -u [file ...] (default: unmark all resolved files)

4.  discard your current attempt(s) at resolving conflicts and restart the merge from scratch: hg resolve file... (or -a for all unresolved files)

    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.

    options:

-a, --all
    select all unresolved files

-l, --list
    list state of files needing merge

-m, --mark
    mark files as resolved

-u, --unmark
    unmark files as resolved

-n, --no-status
    hide status prefix

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

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

    (Use update -r to check out earlier revisions, revert does not change the working directory parents.)

    With no revision specified, revert the named files or directories to the contents they had in the parent of the working directory. This restores the contents of the affected 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 option, revert the given files or directories to their contents as of a specific revision. This can be helpful to "roll back" some or all of an earlier change. See 'hg help dates' for a list of formats valid for -d/--date.

    Revert modifies the working directory. It does not commit any changes, or change the parent of the working directory. If you revert to a revision other than the parent of the working directory, the reverted files will thus appear modified afterwards.

    If a file has been deleted, it is restored. If the executable mode of a file was changed, it is reset.

    If names are given, all files matching the names are reverted. If no arguments are given, no files are reverted.

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

    options:

-a, --all
    revert all changes when no arguments given

-d, --date
    tipmost revision matching date

-r, --rev
    revert to the specified revision

--no-backup
    do not save backup copies of files

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

-n, --dry-run
    do not perform actions, just print output

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

    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.

root

    Print the root directory of the current repository.

serve [OPTION]...

    Start a local HTTP repository browser and pull server. You can use this for ad-hoc sharing and browing 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.

    options:

-A, --accesslog
    name of access log file to write to

-d, --daemon
    run server in background

--daemon-pipefds
    used internally by daemon mode

-E, --errorlog
    name of error log file to write to

-p, --port
    port to listen on (default: 8000)

-a, --address
    address to listen on (default: all interfaces)

--prefix
    prefix path to serve from (default: server root)

-n, --name
    name to show in web pages (default: working directory)

--webdir-conf
    name of the webdir config file (serve more than one repository)

--pid-file
    name of file to write process ID to

--stdio
    for remote clients

-t, --templates
    web templates to use

--style
    template style to use

-6, --ipv6
    use IPv6 in addition to IPv4

--certificate
    SSL certificate file

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.

    options:

-u, --untrusted
    show untrusted configuration options

    aliases: debugconfig

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.

    NOTE: status may appear to disagree with diff if permissions have changed or a merge has occurred. The standard diff format does not report permission changes and diff only reports changes relative to one merge parent.

    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)

    options:

-A, --all
    show status of all files

-m, --modified
    show only modified files

-a, --added
    show only added files

-r, --removed
    show only removed files

-d, --deleted
    show only deleted (but tracked) files

-c, --clean
    show only files without changes

-u, --unknown
    show only unknown (not tracked) files

-i, --ignored
    show only ignored files

-n, --no-status
    hide status prefix

-C, --copies
    show source of copied files

-0, --print0
    end filenames with NUL, for use with xargs

--rev
    show difference from revision

--change
    list the changed files of a revision

-I, --include
    include names matching the given patterns

-X, --exclude
    exclude names matching the given patterns

    aliases: st

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.

    options:

--remote
    check for push and pull

    aliases: sum

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.

    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. The file '.hg/localtags' is used for local tags (not shared among repositories).

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

    options:

-f, --force
    replace existing tag

-l, --local
    make the tag local

-r, --rev
    revision to tag

--remove
    remove a tag

-m, --message
    use <text> as commit message

-d, --date
    record datecode as commit date

-u, --user
    record the specified user as committer

tags

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

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.

    options:

-p, --patch
    show patch

-g, --git
    use git extended diff format

--style
    display using template map file

--template
    display with template

unbundle [-u] FILE...

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

    options:

-u, --update
    update to new branch head if changesets were unbundled

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

    Update the repository's working directory to the specified changeset.

    If no changeset is specified, attempt to update to the head of the current branch. If this head is a descendant of the working directory's parent, update to it, otherwise abort.

    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 update just one file to an older changeset, use 'hg revert'.

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

    options:

-C, --clean
    discard uncommitted changes (no backup)

-c, --check
    check for uncommitted changes

-d, --date
    tipmost revision matching date

-r, --rev
    revision

    aliases: up checkout co

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.

version

    output version and copyright information

CONFIGURATION FILES

Mercurial reads configuration data from several files, if they exist. Below we list the most specific file first.

On Windows, these configuration files are read:

•   <repo>\.hg\hgrc

•   %USERPROFILE%\.hgrc

•   %USERPROFILE%\Mercurial.ini

•   %HOME%\.hgrc

•   %HOME%\Mercurial.ini

•   C:\Mercurial\Mercurial.ini

•   HKEY_LOCAL_MACHINE\SOFTWARE\Mercurial

•   <install-dir>\Mercurial.ini

    On Unix, these files are read:

•   <repo>/.hg/hgrc

•   $HOME/.hgrc

•   /etc/mercurial/hgrc

•   /etc/mercurial/hgrc.d/*.rc

•   <install-root>/etc/mercurial/hgrc

•   <install-root>/etc/mercurial/hgrc.d/*.rc

    The configuration files for Mercurial use a simple ini-file format. A configuration file consists of sections, led by a [section] header and followed by name = value entries:

    [ui]
    username = Firstname Lastname <firstname.lastname@example.net>
    verbose = True

    This above entries will be referred to as ui.username and ui.verbose, respectively. Please see the hgrc man page for a full description of the possible configuration values:

•   on Unix-like systems: man hgrc

•   online: http://www.selenic.com/mercurial/hgrc.5.html

DATE FORMATS

Some commands allow the user to specify a date, e.g.:

•   backout, commit, import, tag: Specify the commit date.

•   log, revert, update: Select revision(s) by date.

    Many date formats are valid. Here are some examples:

•   Wed Dec 6 13:18:29 2006 (local timezone assumed)

•   Dec 6 13:18 -0600 (year assumed, time offset provided)

•   Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)

•   Dec 6 (midnight)

•   13:18 (today assumed)

•   3:39 (3:39AM assumed)

•   3:39pm (15:39)

•   2006-12-06 13:18:29 (ISO 8601 format)

•   2006-12-6 13:18

•   2006-12-6

•   12-6

•   12/6

•   12/6/6 (Dec 6 2006)

    Lastly, there is Mercurial's internal format:

•   1165432709 0 (Wed Dec 6 13:18:29 2006 UTC)

    This is the internal representation format for dates. unixtime is the number of seconds since the epoch (1970-01-01 00:00 UTC). offset is the offset of the local timezone, in seconds west of UTC (negative if the timezone is east of UTC).

    The log command also accepts date ranges:

•   <{datetime} - at or before a given date/time

•   >{datetime} - on or after a given date/time

•   {datetime} to {datetime} - a date range, inclusive

•   -{days} - within a given number of days of today

FILE NAME PATTERNS

Mercurial accepts several notations for identifying one or more files at a time.

By default, Mercurial treats filenames as shell-style extended glob patterns.

Alternate pattern notations must be specified explicitly.

To use a plain path name without any pattern matching, start it with path:. These path names must completely match starting at the current repository root.

To use an extended glob, start a name with glob:. Globs are rooted at the current directory; a glob such as *.c will only match files in the current directory ending with .c.

The supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean "a or b".

To use a Perl/Python regular expression, start a name with re:. Regexp pattern matching is anchored at the root of the repository.

Plain examples:

path:foo/bar   a name bar in a directory named foo in the root
               of the repository
path:path:name a file or directory named "path:name"

Glob examples:

glob:*.c       any name ending in ".c" in the current directory
*.c            any name ending in ".c" in the current directory
**.c           any name ending in ".c" in any subdirectory of the
               current directory including itself.
foo/*.c        any name ending in ".c" in the directory foo
foo/**.c       any name ending in ".c" in any subdirectory of foo
               including itself.

Regexp examples:

re:.*\.c$      any name ending in ".c", anywhere in the repository

ENVIRONMENT VARIABLES

HG  Path to the 'hg' executable, automatically passed when running hooks, extensions or external tools. If unset or empty, this is the hg executable's name if it's frozen, or an executable named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Windows) is searched.

HGEDITOR
    This is the name of the editor to run when committing. See EDITOR.

    (deprecated, use .hgrc)

HGENCODING
    This overrides the default locale setting detected by Mercurial. This setting is used to convert data including usernames, changeset descriptions, tag names, and branches. This setting can be overridden with the --encoding command-line option.

HGENCODINGMODE
    This sets Mercurial's behavior for handling unknown characters while transcoding user input. The default is "strict", which causes Mercurial to abort if it can't map a character. Other settings include "replace", which replaces unknown characters, and "ignore", which drops them. This setting can be overridden with the --encodingmode command-line option.

HGMERGE
    An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file, ancestor file.

    (deprecated, use .hgrc)

HGRCPATH
    A list of files or directories to search for hgrc files. Item separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set, platform default search path is used. If empty, only the .hg/hgrc from the current repository is read.

    For each element in HGRCPATH:

•   if it's a directory, all files ending with .rc are added

•   otherwise, the file itself will be added

HGPLAIN
    When set, this disables any options in .hgrc that might change Mercurial's default output. This includes encoding, defaults, verbose mode, debug mode, quiet mode, tracebacks, and localization. This can be useful when scripting against Mercurial in the face of existing user configuration.

    Equivalent options set via command line flags or environment variables are not overridden.

HGUSER
    This is the string used as the author of a commit. If not set, available values will be considered in this order:

•   HGUSER (deprecated)

•   hgrc files from the HGRCPATH

•   EMAIL

•   interactive prompt

•   LOGNAME (with @hostname appended)

    (deprecated, use .hgrc)

EMAIL
    May be used as the author of a commit; see HGUSER.

LOGNAME
    May be used as the author of a commit; see HGUSER.

VISUAL
    This is the name of the editor to use when committing. See EDITOR.

EDITOR
    Sometimes Mercurial needs to open a text file in an editor for a user to modify, for example when writing commit messages. The editor it uses is determined by looking at the environment variables HGEDITOR, VISUAL and EDITOR, in that order. The first non-empty one is chosen. If all of them are empty, the editor defaults to 'vi'.

PYTHONPATH
    This is used by Python to find imported modules and may need to be set appropriately if this Mercurial is not installed system-wide.

SPECIFYING SINGLE REVISIONS

Mercurial supports several ways to specify individual revisions.

A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth.

A 40-digit hexadecimal string is treated as a unique revision identifier.

A hexadecimal string less than 40 characters long is treated as a unique revision identifier and is referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of exactly one full-length identifier.

Any other string is treated as a tag or branch name. A tag name is a symbolic name associated with a revision identifier. A branch name denotes the tipmost revision of that branch. Tag and branch names must not contain the ":" character.

The reserved name "tip" is a special tag that always identifies the most recent revision.

The reserved name "null" indicates the null revision. This is the revision of an empty repository, and the parent of revision 0.

The reserved name "." indicates the working directory parent. If no working directory is checked out, it is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.

SPECIFYING MULTIPLE REVISIONS

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.

DIFF FORMATS

Mercurial's default format for showing changes between two versions of a file is compatible with the unified format of GNU diff, which can be used by GNU patch and many other standard tools.

While this standard format is often enough, it does not encode the following information:

•   executable status and other permission bits

•   copy or rename information

•   changes in binary files

•   creation or deletion of empty files

    Mercurial also supports the extended diff format from the git VCS which addresses these limitations. The git diff format is not produced by default because a few widespread tools still do not understand this format.

    This means that when generating diffs from a Mercurial repository (e.g. with "hg export"), you should be careful about things like file copies and renames or other things mentioned above, because when applying a standard diff to a different repository, this extra information is lost. Mercurial's internal operations (like push and pull) are not affected by this, because they use an internal binary format for communicating changes.

    To make Mercurial produce the git extended diff format, use the --git option available for many commands, or set 'git = True' in the [diff] section of your hgrc. You do not need to set this option when importing diffs in this format or using them in the mq extension.

TEMPLATE USAGE

Mercurial allows you to customize output of commands through templates. You can either pass in a template from the command line, via the --template option, or select an existing template-style (--style).

You can customize output for any "log-like" command: log, outgoing, incoming, tip, parents, heads and glog.

Four styles are packaged with Mercurial: default (the style used when no explicit preference is passed), compact, changelog, and xml. Usage:

$ hg log -r1 --style changelog

A template is a piece of text, with markup to invoke variable expansion:

$ hg log -r1 --template "{node}\n"
b56ce7b07c52de7d5fd79fb89701ea538af65746

Strings in curly braces are called keywords. The availability of keywords depends on the exact context of the templater. These keywords are usually available for templating a log-like command:

author
    String. The unmodified author of the changeset.

branches
    String. The name of the branch on which the changeset was committed. Will be empty if the branch name was default.

date
    Date information. The date when the changeset was committed.

desc
    String. The text of the changeset description.

diffstat
    String. Statistics of changes with the following format: "modified files: +added/-removed lines"

files
    List of strings. All files modified, added, or removed by this changeset.

file_adds
    List of strings. Files added by this changeset.

file_copies
    List of strings. Files copied in this changeset with their sources.

file_copies_switch
    List of strings. Like "file_copies" but displayed only if the --copied switch is set.

file_mods
    List of strings. Files modified by this changeset.

file_dels
    List of strings. Files removed by this changeset.

node
    String. The changeset identification hash, as a 40-character hexadecimal string.

parents
    List of strings. The parents of the changeset.

rev Integer. The repository-local changeset revision number.

tags
    List of strings. Any tags associated with the changeset.

latesttag
    String. Most recent global tag in the ancestors of this changeset.

latesttagdistance
    Integer. Longest path to the latest tag.

    The "date" keyword does not produce human-readable output. If you want to use a date in your output, you can use a filter to process it. Filters are functions which return a string based on the input variable. Be sure to use the stringify filter first when you're applying a string-input filter to a list-like input variable. You can also use a chain of filters to get the desired output:

    $ hg tip --template "{date|isodate}\n"
    2008-08-21 18:22 +0000

    List of filters:

addbreaks
    Any text. Add an XHTML "<br />" tag before the end of every line except the last.

age Date. Returns a human-readable date/time difference between the given date/time and the current date/time.

basename
    Any text. Treats the text as a path, and returns the last component of the path after splitting by the path separator (ignoring trailing separators). For example, "foo/bar/baz" becomes "baz" and "foo/bar//" becomes "bar".

stripdir
    Treat the text as path and strip a directory level, if possible. For example, "foo" and "foo/bar" becomes "foo".

date
    Date. Returns a date in a Unix date format, including the timezone: "Mon Sep 04 15:13:13 2006 0700".

domain
    Any text. Finds the first string that looks like an email address, and extracts just the domain component. Example: User <user@example.com> becomes example.com.

email
    Any text. Extracts the first string that looks like an email address. Example: User <user@example.com> becomes user@example.com.

escape
    Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML entities.

fill68
    Any text. Wraps the text to fit in 68 columns.

fill76
    Any text. Wraps the text to fit in 76 columns.

firstline
    Any text. Returns the first line of text.

URL PATHS

Valid URLs are of the form:

local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user[:pass]@]host[:port]/[path][#revision]

Paths in the local filesystem can either point to Mercurial repositories or to bundle files (as created by 'hg bundle' or 'hg incoming --bundle').

An optional identifier after # indicates a particular branch, tag, or changeset to use from the remote repository. See also 'hg help revisions'.

Some features, such as pushing to http:// and https:// URLs are only possible if the feature is explicitly enabled on the remote Mercurial server.

Some notes about using SSH with Mercurial:

•   SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path or specified with as remotecmd.

•   path is relative to the remote user's home directory by default. Use an extra slash at the start of a path to specify an absolute path:

    ssh://example.com//tmp/repository

•   Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your ~/.ssh/config, e.g.:

    Host *.mylocalnetwork.example.com
      Compression no
    Host *
      Compression yes

    Alternatively specify "ssh -C" as your ssh command in your hgrc or with the --ssh command line option.

    These URLs can all be stored in your hgrc with path aliases under the [paths] section like so:

    [paths]
    alias1 = URL1
    alias2 = URL2
    ...

    You can then use the alias for any command that uses a URL (for example 'hg pull alias1' will be treated as 'hg pull URL1').

    Two path aliases are special because they are used as defaults when you do not provide the URL to a command:

default:
    When you create a repository with hg clone, the clone command saves the location of the source repository as the new repository's 'default' path. This is then used when you omit path from push- and pull-like commands (including incoming and outgoing).

default-push:
    The push command will look for a path named 'default-push', and prefer it over 'default' if both are defined.

USING ADDITIONAL FEATURES

Mercurial has the ability to add new features through the use of extensions. Extensions may add new commands, add options to existing commands, change the default behavior of commands, or implement hooks.

Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage only; they may provide potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime time; or they may alter some usual behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed.

To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your hgrc, like this:

[extensions]
foo =

You may also specify the full path to an extension:

[extensions]
myfeature = ~/.hgext/myfeature.py

To explicitly disable an extension enabled in an hgrc of broader scope, prepend its path with !:

[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !

FILES

.hgignore

    This file contains regular expressions (one per line) that describe file names that should be ignored by hg. For details, see hgignore(5).

.hgtags

    This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of the repository contents.

/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc

    This file contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc, and these override settings made in the global /etc/mercurial/hgrc configuration. See hgrc(5) for details of the contents and format of these files.

    Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file already exists and is not tracked by Mercurial, it will be overwritten.

BUGS

Probably lots, please post them to the mailing list (see Resources below) when you find them.
