Add all new files and remove all missing files from the

Unless names are given, new files are ignored if they match any of

Use the -s/--similarity option to detect renamed files. This
option takes a percentage between 0 (disabled) and 100 (files must
be identical) as its parameter. With a parameter greater than 0,
this compares every removed file with every added file and records
those similar enough as renames. 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
not specified, -s/--similarity defaults to 100 and only renames of
identical files are detected.

- Reverse the effect of previous bad revision 23 and

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.

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 revisions.bisect` for more about the `bisect()` predicate.
Returns 0 on success.

Bookmarks are labels on changesets to help track lines of development.
Bookmarks are unversioned and can be moved, renamed and deleted.
Deleting or moving a bookmark has no effect on the associated changesets.
Creating or updating to a bookmark causes it to be marked as 'active'.
The active bookmark is indicated with a '*'.
When a commit is made, the active bookmark will advance to the new commit.
A plain :hg:`update` will also advance an active bookmark, if possible.
Updating away from a bookmark will cause it to be deactivated.
Bookmarks can be pushed and pulled between repositories (see
:hg:`help push` and :hg:`help pull`). If a shared bookmark has
diverged, a new 'divergent bookmark' of the form 'name@path' will
be created. Using :hg:`merge` will resolve the divergence.
Specifying bookmark as '.' to -m/-d/-l options is equivalent to specifying
the active bookmark's name.
A bookmark named '@' has the special property that :hg:`clone` will
check it out by default if it exists.

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.
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.
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.
In normal clone mode, the remote normalizes repository data into a common
exchange format and the receiving end translates this data into its local
storage format. --stream activates a different clone mode that essentially
copies repository files from the remote with minimal data processing. This
significantly reduces the CPU cost of a clone both remotely and locally.
However, it often increases the transferred data size by 30-40%. This can
result in substantially faster clones where I/O throughput is plentiful,
especially for larger repositories. A side-effect of --stream clones is
that storage settings and requirements on the remote are applied locally:
a modern client may inherit legacy or inefficient storage used by the
remote or a legacy Mercurial client may not be able to clone from a
modern Mercurial remote.
.. note::
Specifying a tag will include the tagged changeset but not the
changeset containing the tag.
.. 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.
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
When cloning from servers that support it, Mercurial may fetch
pre-generated data from a server-advertised URL or inline from the
same stream. When this is done, hooks operating on incoming changesets
and changegroups may fire more than once, once for each pre-generated
bundle and as well as for any additional remaining data. In addition,
if an error occurs, the repository may be rolled back to a partial
clone. This behavior may change in future releases.
See :hg:`help -e clonebundles` for more.
Examples:
- clone a remote repository to a new directory named hg/::
hg clone https://www.mercurial-scm.org/repo/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 streaming clone while checking out a specified version::
hg clone --stream 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 https://www.mercurial-scm.org/repo/hg/#stable
See :hg:`help urls` for details on specifying URLs.
Returns 0 on success.

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 --close-branch flag can be used to mark the current branch
head closed. When all heads of a branch are closed, the branch
will be considered closed and no longer listed.
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.

:hg:`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. To diff against the
conflict regions, you can use `--config diff.merge=yes`.
By default, the working directory files are compared to its first parent. To
see the differences from another revision, use --from. To see the difference
to another revision, use --to. For example, :hg:`diff --from .^` will show
the differences from the working copy's grandparent to the working copy,
:hg:`diff --to .` will show the diff from the working copy to its parent
(i.e. the reverse of the default), and :hg:`diff --from 1.0 --to 1.2` will
show the diff between those two revisions.
Alternatively you can specify -c/--change with a revision to see the changes
in that changeset relative to its first parent (i.e. :hg:`diff -c 42` is
equivalent to :hg:`diff --from 42^ --to 42`)
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`.

"""dump the header and diffs for one or more changesets
Print the changeset header and diffs for one or more revisions.
If no revision is given, the parent of the working directory is used.
The information shown in the changeset header is: author, date,
branch name (if non-default), changeset hash, parent(s) and commit
comment.
.. note::
:hg:`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 template string. See :hg:`help templates`. In addition
to the common template keywords, the following formatting rules are
supported:
:``%%``: literal "%" character
:``%H``: changeset hash (40 hexadecimal digits)
:``%N``: number of patches being generated
:``%R``: changeset revision number
:``%b``: basename of the exporting repository
:``%h``: short-form changeset hash (12 hexadecimal digits)
:``%m``: first line of the commit message (only alphanumeric characters)
:``%n``: zero-padded sequence number, starting at 1
:``%r``: zero-padded changeset revision number
:``\\``: literal "\\" character
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.
With -B/--bookmark changesets reachable by the given bookmark are
selected.
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.
.. container:: verbose
Template:
The following keywords are supported in addition to the common template
keywords and functions. See also :hg:`help templates`.
:diff: String. Diff content.
:parents: List of strings. Parent nodes of the changeset.
Examples:
- use export and import to transplant a bugfix to the current
branch::
hg export -r 9353 | hg import -
- export all the changesets between two revisions to a file with
rename information::
hg export --git -r 123:150 > changes.txt
- split outgoing changes into a series of patches with
descriptive names::
hg export -r "outgoing()" -o "%n-%m.patch"

def graft(ui, repo, *revs, **opts):
"""copy changes from other branches onto the current branch
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 --log is specified, log messages will have a comment appended
of the form::
(grafted from CHANGESETHASH)
If --force is specified, revisions will be grafted even if they
are already ancestors of, or have been grafted to, the destination.
This is useful when the revisions have since been backed out.
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.
The -c/--continue option reapplies all the earlier options.
.. container:: verbose
The --base option exposes more of how graft internally uses merge with a
custom base revision. --base can be used to specify another ancestor than
the first and only parent.
The command::
hg graft -r 345 --base 234
is thus pretty much the same as::
hg diff --from 234 --to 345 | hg import
but using merge to resolve conflicts and track moved files.
The result of a merge can thus be backported as a single commit by
specifying one of the merge parents as base, and thus effectively
grafting the changes from the other side.
It is also possible to collapse multiple changesets and clean up history
by specifying another ancestor as base, much like rebase --collapse
--keep.
The commit message can be tweaked after the fact using commit --amend .
For using non-ancestors as the base to backout changes, see the backout
command and the hidden --parent option.
.. container:: verbose
Examples:
- copy a single change to the stable branch and edit its description::
hg update stable
hg graft --edit 9393
- graft a range of changesets with one exception, updating dates::
hg graft -D "2085::2093 and not 2091"
- continue a graft after resolving conflicts::
hg graft -c
- show the source of a grafted changeset::
hg log --debug -r .
- show revisions sorted by date::
hg log -r "sort(all(), date)"
- backport the result of a merge as a single commit::
hg graft -r 123 --base 123^
- land a feature branch as one changeset::
hg up -cr default
hg graft -r featureX --base "ancestor('featureX', 'default')"
See :hg:`help revisions` for more about specifying revisions.
Returns 0 on successful completion, 1 if there are unresolved files.

:dirty: String. Character ``+`` denoting if the working directory has
uncommitted changes.
:id: String. One or two nodes, optionally followed by ``+``.
:parents: List of strings. Parent nodes of the changeset.
Examples:
- generate a build identifier for the working directory::
hg id --id > build-id.dat
- find the revision corresponding to a tag::
hg id -n -r 1.3
- check the most recent revision of a remote repository::
hg id -r tip https://www.mercurial-scm.org/repo/hg/

Import a list of patches and commit them individually (unless
--no-commit is specified).
To read a patch from standard input (stdin), use "-" as the patch
name. If a URL is specified, the patch will be downloaded from
there.
Import first applies changes to the working directory (unless
--bypass is specified), import will abort if there are outstanding
changes.
Use --bypass to apply and commit patches directly to the
repository, without affecting the working directory. Without
--exact, patches will be applied on top of the working directory
parent revision.
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 the 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 will guard against various ways that portable
patch formats and mail systems might fail to transfer Mercurial
data or metadata. See :hg:`bundle` for lossless transmission.
Use --partial to ensure a changeset will be created from the patch
even if some hunks fail to apply. Hunks that fail to apply will be
written to a <target-file>.rej file. Conflicts can then be resolved
by hand before :hg:`commit --amend` is run to update the created
changeset. This flag exists to let people import patches that
partially apply without losing the associated metadata (author,
date, description, ...).
.. note::
When no hunks apply cleanly, :hg:`import --partial` will create
an empty changeset, importing only the patch metadata.
With -s/--similarity, hg will attempt to discover renames and
copies in the patch in the same way as :hg:`addremove`.
It is possible to use external patch programs to perform the patch
by setting the ``ui.patch`` configuration option. For the default
internal tool, the fuzz can also be configured via ``patch.fuzz``.
See :hg:`help config` for more information about configuration
files and how to use these options.
See :hg:`help dates` for a list of formats valid for -d/--date.
.. container:: verbose
Examples:
- import a traditional patch from a website and detect renames::
hg import -s 80 http://example.com/bugfix.patch
- import a changeset from an hgweb server::
hg import https://www.mercurial-scm.org/repo/hg/rev/5ca8c111e9aa
- import all the patches in an Unix-style mbox::
hg import incoming-patches.mbox
- import patches from stdin::
hg import -
- attempt to exactly restore an exported changeset (not always
possible)::
hg import --exact proposed-fix.patch
- use an external tool to apply a patch which is too fuzzy for
the default internal tool.
hg import --config ui.patch="patch --merge" fuzzy.patch
- change the default fuzzing from 2 to a less strict 7
hg import --config ui.fuzz=7 fuzz.patch
Returns 0 on success, 1 on partial success (see --partial).

"""show revision history of entire repository or files
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.
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 of the starting revisions. The starting revisions can be
specified by -r/--rev, which default to the working directory parent.
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.
With --graph the revisions are shown as an ASCII art DAG with the most
recent changeset at the top.
'o' is a changeset, '@' is a working directory parent, '%' is a changeset
involved in an unresolved merge conflict, '_' closes a branch,
'x' is obsolete, '*' is unstable, and '+' represents a fork where the
changeset from the lines below is a parent of the 'o' merge on the same
line.
Paths in the DAG are represented with '|', '/' and so forth. ':' in place
of a '|' indicates one or more revisions in a path are omitted.
.. container:: verbose
Use -L/--line-range FILE,M:N options to follow the history of lines
from M to N in FILE. With -p/--patch only diff hunks affecting
specified line range will be shown. This option requires --follow;
it can be specified multiple times. Currently, this option is not
compatible with --graph. This option is experimental.
.. note::
:hg:`log --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:.
.. note::
For performance reasons, :hg:`log FILE` may omit duplicate changes
made on branches and will not show removals or mode changes. To
see all such changes, use the --removed switch.
.. container:: verbose
.. note::
The history resulting from -L/--line-range options depends on diff
options; for instance if white-spaces are ignored, respective changes
with only white-spaces in specified line range will not be listed.
.. container:: verbose
Some examples:
- changesets with full descriptions and file lists::
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"
- the full hash identifier of the working directory parent::
hg log -r . --template "{node}\\n"
- list available log templates::
hg log -T list
- check if a given changeset is included in 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"
- changesets touching lines 13 to 23 for file.c::
hg log -L file.c,13:23
- changesets touching lines 13 to 23 for file.c and lines 2 to 6 of
main.c with patch::
hg log -L file.c,13:23 -L main.c,2:6 -p
See :hg:`help dates` for a list of formats valid for -d/--date.
See :hg:`help revisions` for more about specifying and ordering
revisions.
See :hg:`help templates` for more about pre-packaged styles and
specifying custom templates. The default template used by the log
command can be customized via the ``command-templates.log`` configuration
setting.
Returns 0 on success.

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.
.. note::
Extra care should be taken with the -f/--force option,
which will push all new heads on all branches, an action which will
almost always cause confusion for collaborators.
If -r/--rev is used, the specified revision and all its ancestors
will be pushed to the remote repository.
If -B/--bookmark is used, the specified bookmarked revision, its
ancestors, and the bookmark will be pushed to the remote
repository. Specifying ``.`` is equivalent to specifying the active
bookmark's name. Use the --all-bookmarks option for pushing all
current bookmarks.
Please see :hg:`help urls` for important details about ``ssh://``
URLs. If DESTINATION is omitted, a default path will be used.
When passed multiple destinations, push will process them one after the
other, but stop should an error occur.
.. container:: verbose
The --pushvars option sends strings to the server that become
environment variables prepended with ``HG_USERVAR_``. For example,
``--pushvars ENABLE_FEATURE=true``, provides the server side hooks with
``HG_USERVAR_ENABLE_FEATURE=true`` as part of their environment.
pushvars can provide for user-overridable hooks as well as set debug
levels. One example is having a hook that blocks commits containing
conflict markers, but enables the user to override the hook if the file
is using conflict markers for testing purposes or the file format has
strings that look like conflict markers.
By default, servers will ignore `--pushvars`. To enable it add the
following to your configuration file::
[push]
pushvars.server = true
Returns 0 if push was successful, 1 if nothing to push.

"""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 [--re-merge] [--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.
You can use ``set:unresolved()`` or ``set:resolved()`` to filter
the list. See :hg:`help filesets` for details.
.. note::
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.
.. container:: verbose
Template:
The following keywords are supported in addition to the common template
keywords and functions. See also :hg:`help templates`.
:mergestatus: String. Character denoting merge conflicts, ``U`` or ``R``.

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. It is possible to store
the backup files in a custom directory relative to the root of the
repository by setting the ``ui.origbackuppath`` configuration
option.
See :hg:`help dates` for a list of formats valid for -d/--date.
See :hg:`help backout` for a way to reverse the effect of an
earlier changeset.
Returns 0 on success.

"""roll back the last transaction (DANGEROUS) (DEPRECATED)
Please use :hg:`commit --amend` instead of rollback to correct
mistakes in the last commit.
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.
.. 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.
The rollback command can be entirely disabled by setting the
``ui.rollback`` configuration setting to false. If you're here
because you want to use rollback and it's disabled, you can
re-enable the command by setting ``ui.rollback`` to true.
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.

Shelving takes files that "hg status" reports as not clean, saves
the modifications to a bundle (a shelved change), and reverts the
files so that their state in the working directory becomes clean.
To restore these changes to the working directory, using "hg
unshelve"; this will work even if you switch to a different
commit.
When no files are specified, "hg shelve" saves all not-clean
files. If specific files or directories are named, only changes to
those files are shelved.
In bare shelve (when no files are specified, without interactive,
include and exclude option), shelving remembers information if the
working directory was on newly created branch, in other words working
directory was on different branch than its first parent. In this
situation unshelving restores branch information to the working directory.
Each shelved change has a name that makes it easier to find later.
The name of a shelved change defaults to being based on the active
bookmark, or if there is no active bookmark, the current named
branch. To specify a different name, use ``--name``.
To see a list of existing shelved changes, use the ``--list``
option. For each shelved change, this will print its name, age,
and description; use ``--patch`` or ``--stat`` for more details.
To delete specific shelved changes, use ``--delete``. To delete

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::
:hg:`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 (with --copies)
.. container:: verbose
The -t/--terse option abbreviates the output by showing only the directory
name if all the files in it share the same status. The option takes an
argument indicating the statuses to abbreviate: 'm' for 'modified', 'a'
for 'added', 'r' for 'removed', 'd' for 'deleted', 'u' for 'unknown', 'i'
for 'ignored' and 'c' for clean.
It abbreviates only those statuses which are passed. Note that clean and
ignored files are not displayed with '--terse ic' unless the -c/--clean
and -i/--ignored options are also used.
The -v/--verbose option shows information when the repository is in an
unfinished merge, shelve, rebase state etc. You can have this behavior
turned on by default by enabling the ``commands.status.verbose`` option.
You can skip displaying some of these states by setting
``commands.status.skipstates`` to one or more of: 'bisect', 'graft',
'histedit', 'merge', 'rebase', or 'unshelve'.
Template:
The following keywords are supported in addition to the common template
keywords and functions. See also :hg:`help templates`.
:path: String. Repository-absolute path of the file.
:source: String. Repository-absolute path of the file originated from.
Available if ``--copies`` is specified.
:status: String. Character denoting file's status.
Examples:
- show changes in the working directory relative to a
changeset::
hg status --rev 9353
- show changes in the working directory relative to the
current directory (see :hg:`help patterns` for more information)::
hg status re:
- show all changes including copies in an existing changeset::
hg status --copies --change 9353
- get a NUL separated list of added files, suitable for xargs::
hg status -an0
- show more information about the repository status, abbreviating
added, removed, modified, deleted, and untracked paths::

Tags are used to name particular revisions of the repository and are

an existing tag is normally disallowed; use -f/--force to override.
If no revision is given, the parent of the working directory is
used.
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.

This command accepts an optional name of a shelved change to
restore. If none is given, the most recent shelved change is used.
If a shelved change is applied successfully, the bundle that
contains the shelved changes is moved to a backup location
(.hg/shelve-backup).
Since you can restore a shelved change on top of an arbitrary
commit, it is possible that unshelving will result in a conflict
between your changes and the commits you are unshelving onto. If
this occurs, you must resolve the conflict, then use
``--continue`` to complete the unshelve operation. (The bundle
will not be moved until you successfully complete the unshelve.)
(Alternatively, you can use ``--abort`` to abandon an unshelve
that causes a conflict. This reverts the unshelved changes, and
leaves the bundle in place.)
If bare shelved change (without interactive, include and exclude
option) was done on newly created branch it would restore branch
information to the working directory.
After a successful unshelve, the shelved changes are stored in a
backup directory. Only the N most recent backups are kept. N
defaults to 10 but can be overridden using the ``shelve.maxbackups``
configuration option.
.. container:: verbose
Timestamp in seconds is used to decide order of backups. More
than ``maxbackups`` backups are kept, if same timestamp
prevents from deciding exact order of them, for safety.
Selected changes can be unshelved with ``--interactive`` flag.
The working directory is updated with the selected changes, and
only the unselected changes remain shelved.
Note: The whole shelve is applied to working directory first before
running interactively. So, this will bring up all the conflicts between
working directory and the shelve, irrespective of which changes will be
unshelved.
