Examples:
- create a zip file containing the 1.0 release::

- create a tarball excluding .hg files::
hg archive project.tar.gz -X ".hg*"
Valid types are:

:``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.

maintaining a linear history. With --merge, the pending
changeset will instead have two parents: the old parent of the
working directory and a new child of REV that simply undoes REV.
Before version 1.7, the behavior without --merge was equivalent
to specifying --merge followed by :hg:`update --clean .` to
cancel the merge and leave the child of REV as a head to be
merged separately.

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.
The environment variable HG_NODE will contain the ID of the
changeset being tested. The exit status of the command 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.
.. container:: verbose
Some examples:
- start a bisection with known bad revision 34, and good revision 12::
hg bisect --bad 34
hg bisect --good 12
- advance the current bisection by marking current revision as good or
bad::
hg bisect --good
hg bisect --bad
- mark the current revision, or a known revision, to be skipped (e.g. if
that revision is not usable because of another issue)::
hg bisect --skip
hg bisect --skip 23
- skip all revisions that do not touch directories ``foo`` or ``bar``::
hg bisect --skip "!( file('path:foo') & file('path:bar') )"
- forget the current bisection::
hg bisect --reset
- use 'make && make tests' to automatically find the first broken
revision::
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command "make && make tests"
- see all changesets whose states are already known in the current
bisection::
hg log -r "bisect(pruned)"
- see the changeset currently being bisected (especially useful
if running with -U/--noupdate)::
hg log -r "bisect(current)"
- see all changesets that took part in the current bisection::
hg log -r "bisect(range)"
- you can even get a nice graph::
hg log --graph -r "bisect(range)"
See :hg:`help revsets` for more about the `bisect()` keyword.

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

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.
If the source repository has a bookmark called '@' set, that
revision will be checked out in the new repository by default.
To check out a particular version, use -u/--update, or
-U/--noupdate to create a clone with no working directory.
.. container:: verbose
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 revision marked with the '@' bookmark, if present
h) the tipmost head of the default branch
i) tip
Examples:
- clone a remote repository to a new directory named hg/::
hg clone http://selenic.com/hg
- create a lightweight local clone::
hg clone project/ project-feature/
- clone from an absolute path on an ssh server (note double-slash)::
hg clone ssh://user@server//home/projects/alpha/
- do a high-speed clone over a LAN while checking out a
specified version::
hg clone --uncompressed http://server/repo -u 1.5
- create a repository without changesets after a particular revision::
hg clone -r 04e544 experimental/ good/
- clone (and track) a particular named branch::
hg clone http://selenic.com/hg#stable

When two revision arguments are given, then changes are shown

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

This command uses Mercurial's merge logic to copy individual

description from the source changesets.

If --log is specified, log messages will have a comment appended
of the form::

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.

- graft a range of changesets with one exception, updating dates::
hg graft -D "2085::2093 and not 2091"
- continue a graft after resolving conflicts::

- show the source of a grafted changeset::

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

hg log -v
- changesets ancestral to the working directory::
hg log -f
- last 10 commits on the current branch::
hg log -l 10 -b .
- changesets showing all modifications of a file, including removals::
hg log --removed file.c
- all changesets that touch a directory, with diffs, excluding merges::
hg log -Mp lib/
- all revision numbers that match a keyword::
hg log -k bug --template "{rev}\\n"
- check if a given changeset is included is a tagged release::
hg log -r "a21ccf and ancestor(1.9)"
- find all changesets by some user in a date range::
hg log -k alice -d "may 2008 to jul 2008"
- summary of all changesets after the last tag::
hg log -r "last(tagged())::" --template "{desc|firstline}\\n"

"""redo merges or set/view the merge status of files
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.

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.
.. container:: verbose
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

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`).
Update sets the working directory's parent revision to the specified
changeset (see :hg:`help parents`).
If the changeset is not a descendant or ancestor 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.
.. container:: verbose
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.
To cancel an uncommitted merge (and lose your changes), use
:hg:`update --clean .`.
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.
