NAME

6       git-contacts - List people who might be interested in a set of changes
7

SYNOPSIS

9       git contacts (<patch>|<range>|<rev>)...
10

DESCRIPTION

12       Given a set of changes, specified as patch files or revisions,
13       determine people who might be interested in those changes. This is done
14       by consulting the history of each patch or revision hunk to find people
15       mentioned by commits which touched the lines of files under
16       consideration.
17
18       Input consists of one or more patch files or revision arguments. A
19       revision argument can be a range or a single <rev> which is interpreted
20       as <rev>..HEAD, thus the same revision arguments are accepted as for
21       git-format-patch(1). Patch files and revision arguments can be combined
22       in the same invocation.
23
24       This command can be useful for determining the list of people with whom
25       to discuss proposed changes, or for finding the list of recipients to
26       Cc: when submitting a patch series via git send-email. For the latter
27       case, git contacts can be used as the argument to git send-email's
28       --cc-cmd option.
29

DISCUSSION

31       git blame is invoked for each hunk in a patch file or revision. For
32       each commit mentioned by git blame, the commit message is consulted for
33       people who authored, reviewed, signed, acknowledged, or were Cc:'d.
34       Once the list of participants is known, each person’s relevance is
35       computed by considering how many commits mentioned that person compared
36       with the total number of commits under consideration. The final output
37       consists only of participants who exceed a minimum threshold of
38       participation.
39

OUTPUT

41       For each person of interest, a single line is output, terminated by a
42       newline. If the person’s name is known, “Name <user@host>” is printed;
43       otherwise only “<user@host>” is printed.
44

EXAMPLES

46       ·   Consult patch files:
47
48               $ git contacts feature/*.patch
49
50       ·   Revision range:
51
52               $ git contacts R1..R2
53
54       ·   From a single revision to HEAD:
55
56               $ git contacts origin
57
58       ·   Helper for git send-email:
59
60               $ git send-email --cc-cmd='git contacts' feature/*.patch
61

LIMITATIONS

63       Several conditions controlling a person’s significance are currently
64       hard-coded, such as minimum participation level (10%), blame
65       date-limiting (5 years), and -C level for detecting moved and copied
66       lines (a single -C). In the future, these conditions may become
67       configurable.
