1 | 1 | Mercurial supports a functional language for selecting a set of |
|
2 | 2 | files. |
|
3 | 3 | |
|
4 | 4 | Like other file patterns, this pattern type is indicated by a prefix, |
|
5 | 5 | 'set:'. The language supports a number of predicates which are joined |
|
6 | 6 | by infix operators. Parenthesis can be used for grouping. |
|
7 | 7 | |
|
8 | 8 | Identifiers such as filenames or patterns must be quoted with single |
|
9 | 9 | or double quotes if they contain characters outside of |
|
10 | 10 | ``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the |
|
11 | 11 | predefined predicates. This generally applies to file patterns other |
|
12 | 12 | than globs and arguments for predicates. |
|
13 | 13 | |
|
14 | 14 | Special characters can be used in quoted identifiers by escaping them, |
|
15 | 15 | e.g., ``\n`` is interpreted as a newline. To prevent them from being |
|
16 | 16 | interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. |
|

20 | 20 | Operators |
|
21 | 21 | ========= |
|
22 | 22 | |
|
23 | 23 | There is a single prefix operator: |
|
24 | 24 | |
|
25 | 25 | ``not x`` |
|
26 | 26 | Files not in x. Short form is ``! x``. |
|
27 | 27 | |
|
28 | 28 | These are the supported infix operators: |
|
29 | 29 | |
|
30 | 30 | ``x and y`` |
|
31 | 31 | The intersection of files in x and y. Short form is ``x & y``. |
|
32 | 32 | |
|
33 | 33 | ``x or y`` |
|
34 | 34 | The union of files in x and y. There are two alternative short |
|
35 | 35 | forms: ``x | y`` and ``x + y``. |
|
36 | 36 | |
|
37 | 37 | ``x - y`` |
|
38 | 38 | Files in x but not in y. |
|
39 | 39 | |
|
40 | 40 | Predicates |
|
41 | 41 | ========== |
|
42 | 42 | |
|
43 | 43 | The following predicates are supported: |
|
44 | 44 | |
|
45 | 45 | .. predicatesmarker |
|
46 | 46 | |
|
47 | 47 | Examples |
|
48 | 48 | ======== |
|
49 | 49 | |
|
50 | 50 | Some sample queries: |
|
51 | 51 | |
|
52 | 52 | - Show status of files that appear to be binary in the working directory:: |
|
53 | 53 | |
|
54 | 54 | hg status -A "set:binary()" |
|
55 | 55 | |
|
56 | 56 | - Forget files that are in .hgignore but are already tracked:: |
|
57 | 57 | |
|
58 | 58 | hg forget "set:hgignore() and not ignored()" |
|
59 | 59 | |
|
60 | 60 | - Find text files that contain a string:: |
|
61 | 61 | |
|
62 | 62 | hg files "set:grep(magic) and not binary()" |
|
63 | 63 | |
|
64 | 64 | - Find C files in a non-standard encoding:: |
|
65 | 65 | |
|
66 | 66 | hg files "set:**.c and not encoding('UTF-8')" |
|
67 | 67 | |
|
68 | 68 | - Revert copies of large binary files:: |
|
69 | 69 | |
|
70 | 70 | hg revert "set:copied() and binary() and size('>1M')" |
|
71 | 71 | |
|
72 | 72 | - Revert files that were added to the working directory:: |
|
73 | 73 | |
|
74 | hg revert "set:wdir(added())" | |
|
74 | hg revert "set:revs('wdir()', added())" | |
|
75 | 75 | |
|
76 | 76 | - Remove files listed in foo.lst that contain the letter a or b:: |
|
77 | 77 | |
|
78 | 78 | hg remove "set: 'listfile:foo.lst' and (**a* or **b*)" |
