r11382 | Mercurial supports a functional language for selecting a set of | ||
revisions. | ||||
The language supports a number of predicates which are joined by infix | ||||
operators. Parenthesis can be used for grouping. | ||||
Identifiers such as branch names must be quoted with single or double | ||||
|
r11420 | quotes if they contain characters outside of | ||
``[._a-zA-Z0-9\x80-\xff]`` or if they match one of the predefined | ||||
|
r12408 | predicates. | ||
Special characters can be used in quoted identifiers by escaping them, | ||||
e.g., ``\n`` is interpreted as a newline. To prevent them from being | ||||
interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. | ||||
|
r11382 | |||
There is a single prefix operator: | ||||
``not x`` | ||||
Changesets not in x. Short form is ``! x``. | ||||
These are the supported infix operators: | ||||
``x::y`` | ||||
A DAG range, meaning all changesets that are descendants of x and | ||||
ancestors of y, including x and y themselves. If the first endpoint | ||||
is left out, this is equivalent to ``ancestors(y)``, if the second | ||||
|
r11450 | is left out it is equivalent to ``descendants(x)``. | ||
|
r11382 | |||
An alternative syntax is ``x..y``. | ||||
``x:y`` | ||||
All changesets with revision numbers between x and y, both | ||||
inclusive. Either endpoint can be left out, they default to 0 and | ||||
tip. | ||||
``x and y`` | ||||
The intersection of changesets in x and y. Short form is ``x & y``. | ||||
``x or y`` | ||||
The union of changesets in x and y. There are two alternative short | ||||
forms: ``x | y`` and ``x + y``. | ||||
``x - y`` | ||||
Changesets in x but not in y. | ||||
The following predicates are supported: | ||||
``adds(pattern)`` | ||||
Changesets that add a file matching pattern. | ||||
``all()`` | ||||
All changesets, the same as ``0:tip``. | ||||
``ancestor(single, single)`` | ||||
Greatest common ancestor of the two changesets. | ||||
``ancestors(set)`` | ||||
Changesets that are ancestors of a changeset in set. | ||||
``author(string)`` | ||||
Alias for ``user(string)``. | ||||
``branch(set)`` | ||||
|
r11684 | All changesets belonging to the branches of changesets in set. | ||
|
r11382 | |||
``children(set)`` | ||||
Child changesets of changesets in set. | ||||
``closed()`` | ||||
Changeset is closed. | ||||
``contains(pattern)`` | ||||
Revision contains pattern. | ||||
``date(interval)`` | ||||
Changesets within the interval, see :hg:`help dates`. | ||||
``descendants(set)`` | ||||
|
r11684 | Changesets which are descendants of changesets in set. | ||
|
r11382 | |||
``file(pattern)`` | ||||
|
r11684 | Changesets affecting files matched by pattern. | ||
|
r11382 | |||
``follow()`` | ||||
An alias for ``::.`` (ancestors of the working copy's first parent). | ||||
``grep(regex)`` | ||||
|
r12408 | Like ``keyword(string)`` but accepts a regex. Use ``grep(r'...')`` | ||
to ensure special escape characters are handled correctly. | ||||
|
r11382 | |||
``head()`` | ||||
Changeset is a head. | ||||
``heads(set)`` | ||||
Members of set with no children in set. | ||||
``keyword(string)`` | ||||
Search commit message, user name, and names of changed files for | ||||
string. | ||||
``limit(set, n)`` | ||||
First n members of set. | ||||
``max(set)`` | ||||
Changeset with highest revision number in set. | ||||
|
r11708 | ``min(set)`` | ||
Changeset with lowest revision number in set. | ||||
|
r11382 | ``merge()`` | ||
Changeset is a merge changeset. | ||||
``modifies(pattern)`` | ||||
|
r11684 | Changesets modifying files matched by pattern. | ||
|
r11382 | |||
``outgoing([path])`` | ||||
|
r11684 | Changesets not found in the specified destination repository, or the | ||
default push location. | ||||
|
r11382 | |||
``p1(set)`` | ||||
First parent of changesets in set. | ||||
``p2(set)`` | ||||
Second parent of changesets in set. | ||||
``parents(set)`` | ||||
The set of all parents for all changesets in set. | ||||
|
r11944 | ``present(set)`` | ||
An empty set, if any revision in set isn't found; otherwise, | ||||
all revisions in set. | ||||
|
r11382 | ``removes(pattern)`` | ||
Changesets which remove files matching pattern. | ||||
``reverse(set)`` | ||||
Reverse order of set. | ||||
``roots(set)`` | ||||
Changesets with no parent changeset in set. | ||||
``sort(set[, [-]key...])`` | ||||
Sort set by keys. The default sort order is ascending, specify a key | ||||
as ``-key`` to sort in descending order. | ||||
The keys can be: | ||||
- ``rev`` for the revision number, | ||||
- ``branch`` for the branch name, | ||||
- ``desc`` for the commit message (description), | ||||
- ``user`` for user name (``author`` can be used as an alias), | ||||
- ``date`` for the commit date | ||||
``tagged()`` | ||||
Changeset is tagged. | ||||
``user(string)`` | ||||
User name is string. | ||||
Command line equivalents for :hg:`log`:: | ||||
-f -> ::. | ||||
-d x -> date(x) | ||||
-k x -> keyword(x) | ||||
-m -> merge() | ||||
-u x -> user(x) | ||||
-b x -> branch(x) | ||||
-P x -> !::x | ||||
-l x -> limit(expr, x) | ||||
Some sample queries:: | ||||
hg log -r 'branch(default)' | ||||
hg log -r 'branch(default) and 1.5:: and not merge()' | ||||
hg log -r '1.3::1.5 and keyword(bug) and file("hgext/*")' | ||||
hg log -r 'sort(date("May 2008"), user)' | ||||
hg log -r '(keyword(bug) or keyword(issue)) and not ancestors(tagged())' | ||||
