1 Load extension:

3 $ echo "[extensions]" >> $HGRCPATH
4 $ echo "onsub = $TESTDIR/onsub.py" >> $HGRCPATH
5
6 Check help formatting:
7
8 $ hg help onsub
9 hg onsub [-b] [-0] CMD
10
11 execute a command in each subrepository
12
13 The command is executed with the current working directory set to the root
14 of each subrepository. By default, execution stops if the command returns
15 a non-zero exit code. Use --ignore-errors to override this.
16
17 Use --verbose/-v to print the name of each subrepo before the command is
18 executed, use --print0/-0 to terminate this line with a NUL character
19 instead of a newline. This can for instance be useful in combination with
20 "hg status --print0".
21
22 The command has access to the following environment variables:
23
24 "HG_REPO":
25 Absolute path to the top-level repository in which the onsub command
26 was executed.
27
28 "HG_SUBPATH":
29 Relative path to the current subrepository from the top-level
30 repository.
31
32 "HG_SUBURL":
33 URL for the current subrepository as specified in the containing
34 repository's ".hgsub" file.
35
36 "HG_SUBSTATE":
37 State of the current subrepository as specified in the containing
38 repository's ".hgsubstate" file.
39
40 options:
41
42 -b --breadth-first use breadth-first traversal
43 -0 --print0 end subrepository names with NUL, for use with xargs
44
45 use "hg -v help onsub" to show global options
46
47 Create some nicely nested subrepositories:
48
49 $ hg init
50 $ for d in a b; do hg init $d; echo "$d = $d" >> .hgsub; done
51 $ hg add .hgsub
52
53 $ cd a
54
55 $ for d in x y; do hg init $d; echo "$d = $d" >> .hgsub; done
56 $ hg add .hgsub
57
58 $ cd y
59 $ for d in r s t; do hg init $d; echo "$d = $d" >> .hgsub; done
60 $ hg add .hgsub
61 $ cd ..
62
63 $ cd ..
64
65 $ cd b
66 $ for d in u v; do hg init $d; echo "$d = $d" >> .hgsub; done
67 $ hg add .hgsub
68 $ cd ..
69
70 $ hg commit -m init
71 committing subrepository a
72 committing subrepository a/x
73 committing subrepository a/y
74 committing subrepository a/y/r
75 committing subrepository a/y/s
76 committing subrepository a/y/t
77 committing subrepository b
78 committing subrepository b/u
79 committing subrepository b/v
80
81 The default depth-first traversal:
82
83 $ hg onsub 'echo $HG_SUBPATH'
84 a
85 a/x
86 a/y
87 a/y/r
88 a/y/s
89 a/y/t
90 b
91 b/u
92 b/v
93
94 Breadth-first traversal:
95
96 $ hg onsub 'echo $HG_SUBPATH' --breadth-first
97 a
98 b
99 a/x
100 a/y
101 b/u
102 b/v
103 a/y/r
104 a/y/s
105 a/y/t
106
107 Test aborting:
108
109 $ hg onsub -v 'test $HG_SUBPATH != "a/y/r"'
110 executing 'test $HG_SUBPATH != "a/y/r"' in a
111 executing 'test $HG_SUBPATH != "a/y/r"' in a/x
112 executing 'test $HG_SUBPATH != "a/y/r"' in a/y
113 executing 'test $HG_SUBPATH != "a/y/r"' in a/y/r
114 abort: terminated onsub in a/y/r: test exited with status 1
115
116 Test --print0:
117
118 $ mv a 'with spaces'
119 $ echo 'with spaces = with spaces' > .hgsub
120 $ echo 'b = b' >> .hgsub
121 $ hg commit -m rename
122 committing subrepository with spaces
123 $ hg onsub -0 | xargs -n 1 -0
124 b
125 b/u
126 b/v
127 with spaces
128 with spaces/x
129 with spaces/y
130 with spaces/y/r
131 with spaces/y/s
132 with spaces/y/t
