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: | ||||
|
r12821 | .. predicatesmarker | ||
|
r11382 | |||
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) | ||||
|
