In recursive mode (the default), files are treated the same way

The following options can be used to control what information is
2000
-l N display a maximum of N revisions
2001
-n N display N levels of revisions (0 for all, 1 for collapsed)
2002
-v display a status summary (delta) for each revision
2003
-p display a diff (patch) for each revision
2004
--show-ids display revision-ids (and file-ids), not just revnos
2006
Note that the default number of levels to display is a function of the
2007
log format. If the -n option is not used, the standard log formats show
2008
just the top level (mainline).
2010
Status summaries are shown using status flags like A, M, etc. To see
2011
the changes explained using words like ``added`` and ``modified``
2012
instead, use the -vv option.
2016
To display revisions from oldest to newest, use the --forward option.
2017
In most cases, using this option will have little impact on the total
2018
time taken to produce a log, though --forward does not incrementally
2019
display revisions like --reverse does when it can.
2021
:Revision filtering:
2023
The -r option can be used to specify what revision or range of revisions
2024
to filter against. The various forms are shown below::
2026
-rX display revision X
2027
-rX.. display revision X and later
2028
-r..Y display up to and including revision Y
2029
-rX..Y display from X to Y inclusive
2031
See ``bzr help revisionspec`` for details on how to specify X and Y.
2032
Some common examples are given below::
2034
-r-1 show just the tip
2035
-r-10.. show the last 10 mainline revisions
2036
-rsubmit:.. show what's new on this branch
2037
-rancestor:path.. show changes since the common ancestor of this
2038
branch and the one at location path
2039
-rdate:yesterday.. show changes since yesterday
2041
When logging a range of revisions using -rX..Y, log starts at
2042
revision Y and searches back in history through the primary
2043
("left-hand") parents until it finds X. When logging just the
2044
top level (using -n1), an error is reported if X is not found
2045
along the way. If multi-level logging is used (-n0), X may be
2046
a nested merge revision and the log will be truncated accordingly.
2050
If parameters are given and the first one is not a branch, the log
2051
will be filtered to show only those revisions that changed the
2052
nominated files or directories.
2054
Filenames are interpreted within their historical context. To log a
2055
deleted file, specify a revision range so that the file existed at
2056
the end or start of the range.
2058
Historical context is also important when interpreting pathnames of
2059
renamed files/directories. Consider the following example:
2061
* revision 1: add tutorial.txt
2062
* revision 2: modify tutorial.txt
2063
* revision 3: rename tutorial.txt to guide.txt; add tutorial.txt
2067
* ``bzr log guide.txt`` will log the file added in revision 1
2069
* ``bzr log tutorial.txt`` will log the new file added in revision 3
2071
* ``bzr log -r2 -p tutorial.txt`` will show the changes made to
2072
the original file in revision 2.
2074
* ``bzr log -r2 -p guide.txt`` will display an error message as there
2075
was no file called guide.txt in revision 2.
2077
Renames are always followed by log. By design, there is no need to
2078
explicitly ask for this (and no way to stop logging a file back
2079
until it was last renamed).
2083
The --message option can be used for finding revisions that match a
2084
regular expression in a commit message.
2088
GUI tools and IDEs are often better at exploring history than command
2089
line tools. You may prefer qlog or glog from the QBzr and Bzr-Gtk packages
2090
respectively for example. (TortoiseBzr uses qlog for displaying logs.) See
2091
http://bazaar-vcs.org/BzrPlugins and http://bazaar-vcs.org/IDEIntegration.
2093
Web interfaces are often better at exploring history than command line
2094
tools, particularly for branches on servers. You may prefer Loggerhead
2095
or one of its alternatives. See http://bazaar-vcs.org/WebInterface.
2097
You may find it useful to add the aliases below to ``bazaar.conf``::
2101
top = log -l10 --line
2104
``bzr tip`` will then show the latest revision while ``bzr top``
2105
will show the last 10 mainline revisions. To see the details of a
2106
particular revision X, ``bzr show -rX``.
2108
If you are interested in looking deeper into a particular merge X,
2109
use ``bzr log -n0 -rX``.
2111
``bzr log -v`` on a branch with lots of history is currently
2112
very slow. A fix for this issue is currently under development.
2113
With or without that fix, it is recommended that a revision range
2114
be given when using the -v option.
2116
bzr has a generic full-text matching plugin, bzr-search, that can be
2117
used to find revisions matching user names, commit messages, etc.
2118
Among other features, this plugin can find all revisions containing
2119
a list of words but not others.
2121
When exploring non-mainline history on large projects with deep
2122
history, the performance of log can be greatly improved by installing
2123
the historycache plugin. This plugin buffers historical information
2124
trading disk space for faster speed.

"""Commit changes into a new revision.
2770
An explanatory message needs to be given for each commit. This is
2771
often done by using the --message option (getting the message from the
2772
command line) or by using the --file option (getting the message from
2773
a file). If neither of these options is given, an editor is opened for
2774
the user to enter the message. To see the changed files in the
2775
boilerplate text loaded into the editor, use the --show-diff option.
2777
By default, the entire tree is committed and the person doing the
2778
commit is assumed to be the author. These defaults can be overridden
2783
If selected files are specified, only changes to those files are
2784
committed. If a directory is specified then the directory and
2785
everything within it is committed.
2787
When excludes are given, they take precedence over selected files.
2788
For example, to commit only changes within foo, but not changes
2791
bzr commit foo -x foo/bar
2793
A selective commit after a merge is not yet supported.
2797
If the author of the change is not the same person as the committer,
2798
you can specify the author's name using the --author option. The
2799
name should be in the same format as a committer-id, e.g.
2800
"John Doe <jdoe@example.com>". If there is more than one author of
2801
the change you can specify the option multiple times, once for each
2806
A common mistake is to forget to add a new file or directory before
2807
running the commit command. The --strict option checks for unknown
2808
files and aborts the commit if any are found. More advanced pre-commit
2809
checks can be implemented by defining hooks. See ``bzr help hooks``
2814
If you accidentially commit the wrong changes or make a spelling
2815
mistake in the commit message say, you can use the uncommit command
2816
to undo it. See ``bzr help uncommit`` for details.
2818
Hooks can also be configured to run after a commit. This allows you
2819
to trigger updates to external systems like bug trackers. The --fixes
2820
option can be used to record the association between a revision and
2821
one or more bugs. See ``bzr help bugs`` for details.
2823
A selective commit may fail in some cases where the committed
2824
tree would be invalid. Consider::
2829
bzr commit foo -m "committing foo"
2830
bzr mv foo/bar foo/baz
2833
bzr commit foo/bar -m "committing bar but not baz"
2835
In the example above, the last commit will fail by design. This gives
2836
the user the opportunity to decide whether they want to commit the
2837
rename at the same time, separately first, or not at all. (As a general
2838
rule, when in doubt, Bazaar has a policy of Doing the Safe Thing.)

The source of the merge can be specified either in the form of a branch,
3471
or in the form of a path to a file containing a merge directive generated
3472
with bzr send. If neither is specified, the default is the upstream branch
3473
or the branch most recently merged using --remember.
3475
When merging a branch, by default the tip will be merged. To pick a different
3476
revision, pass --revision. If you specify two values, the first will be used as
3477
BASE and the second one as OTHER. Merging individual revisions, or a subset of
3478
available revisions, like this is commonly referred to as "cherrypicking".
3480
Revision numbers are always relative to the branch being merged.
3482
By default, bzr will try to merge in all new work from the other
3483
branch, automatically determining an appropriate base. If this
3484
fails, you may need to give an explicit base.
3486
Merge will do its best to combine the changes in two branches, but there
3487
are some kinds of problems only a human can fix. When it encounters those,
3488
it will mark a conflict. A conflict means that you need to fix something,
3489
before you should commit.
3491
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
3493
If there is no default branch set, the first merge will set it. After
3494
that, you can omit the branch to use the default. To change the
3495
default, use --remember. The value will only be saved if the remote
3496
location can be accessed.
3498
The results of the merge are placed into the destination working
3499
directory, where they can be reviewed (with bzr diff), tested, and then

To remove only some changes, without reverting to a prior version, use

A merge directive provides many things needed for requesting merges:
4834
* A machine-readable description of the merge to perform
4836
* An optional patch that is a preview of the changes requested
4838
* An optional bundle of revision data, so that the changes can be applied

directly from the merge directive, without retrieving data from a

If --no-bundle is specified, then public_branch is needed (and must be
4843
up-to-date), so that the receiver can perform the merge using the
4844
public_branch. The public_branch is always included if known, so that
4845
people can check it later.
4847
The submit branch defaults to the parent, but can be overridden. Both
4848
submit branch and public branch will be remembered if supplied.
4850
If a public_branch is known for the submit_branch, that public submit
4851
branch is used in the merge instructions. This means that a local mirror
4852
can be used as your actual submit branch, once you have set public_branch
4855
Mail is sent using your preferred mail program. This should be transparent
4856
on Windows (it uses MAPI). On Linux, it requires the xdg-email utility.
4857
If the preferred client can't be found (or used), your editor will be used.
4859
To use a specific mail program, set the mail_client configuration option.
4860
(For Thunderbird 1.5, this works around some bugs.) Supported values for
4861
specific clients are "claws", "evolution", "kmail", "mutt", and
4862
"thunderbird"; generic options are "default", "editor", "emacsclient",
4863
"mapi", and "xdg-email". Plugins may also add supported clients.
4865
If mail is being sent, a to address is required. This can be supplied
4866
either on the commandline, by setting the submit_to configuration
4867
option in the branch itself or the child_submit_to configuration option
4868
in the submit branch.
4870
Two formats are currently supported: "4" uses revision bundle format 4 and
4871
merge directive format 2. It is significantly faster and smaller than
4872
older formats. It is compatible with Bazaar 0.19 and later. It is the
4873
