Revision identifiers and ranges
5
-------------------------------
7
Bazaar has a very expressive way to specify a revision or a range of revisions.
8
To specify a range of revisions, the upper and lower bounds are separated by the
9
``..`` symbol. For example::
13
You can omit one bound like::
18
Some commands take only one revision, not a range. For example::
22
In other cases, a range is required but you want the length of the range to
23
be one. For commands where this is relevant, the ``-c`` option is used like this::

The revision, or the bounds of the range, can be given using
32
different format specifications as shown below.

A brief introduction to some of these formats is given below.

73
Positive numbers denote revision numbers in the current branch. Revision
74
numbers are labelled as "revno" in the output of ``bzr log``. To display
75
the log for the first ten revisions::
79
Negative numbers count from the latest revision, -1 is the last committed
82
To display the log for the last ten revisions::
89
**revid** allows specifying a an internal revision ID, as shown by ``bzr
90
log --show-ids`` and some other commands.
94
$ bzr log -r revid:Matthieu.Moy@imag.fr-20051026185030-93c7cad63ee570df
100
''rev'' specifies the leftmost parent of ''rev'', that is the revision
101
that appears before ''rev'' in the revision history, or the revision that
102
was current when ''rev'' was committed.
104
''rev'' can be any revision specifier and may be chained.
108
$ bzr log -r before:before:4
117
''value'' matches the first history entry after a given date, either at
118
midnight or at a specified time.
125
* A **YYYY-MM-DD** format date.
126
* A **YYYY-MM-DD,HH:MM:SS** format date/time, seconds are optional (note the
129
The proper way of saying "give me all the log entries for today" is::
131
$ bzr log -r date:yesterday..date:today
137
specifies the common ancestor between the current branch and a
138
different branch. This is the same ancestor that would be used for
141
*path* may be the URL of a remote branch, or the file path to a local branch.
143
For example, to see what changes were made on a branch since it was forked
146
$ bzr diff -r ancestor:../parent
152
``path`` specifies the latest revision in another branch.
154
``path`` may be the URL of a remote branch, or the file path to a local branch.
156
For example, to get the differences between this and another branch::
158
$ bzr diff -r branch:http://example.com/bzr/foo.dev
