如何为git commit消息设置模式？

Question

我想限制那些提交具有特定提交消息格式的人,我该怎么做？

例如: Pair_Name|Story_Number|Commit_Message

有一个pre-commit-msg或commit-msg钩子,你可以使用:

• http://www.kernel.org/pub/software/scm/git/docs/githooks.html

Git repos带有样品钩,例如捕获commit-msg下的样品钩git/hooks/commit-msg.sample重复签名.

# This example catches duplicate Signed-off-by lines.

test "" = "$(grep '^Signed-off-by: ' "$1" |
    sort | uniq -c | sed -e '/^[   ]*1[    ]/d')" || {
    echo >&2 Duplicate Signed-off-by lines.
    exit 1
}

要启用挂钩,请不要忘记使其可执行.

 

这是一些虚构的例子,它只接受提交消息london|120|something ...等:

#!/usr/bin/env ruby
message_file = ARGV[0]
message = File.read(message_file)

# $regex = /\[ref: (\d+)\]/

PAIRS = ["london", "paris", "moscow"] # only these names allowed
STORIES = "\d{2,4}"                   # story must be a 2, 3 or 4 digit number
MESSAGE = ".{5,}"                     # message must be at least 5 chars long

$regex = "( (#{PAIRS.join('|')})\|#{STORIES}\|#{MESSAGE} )"

if !$regex.match(message)
  puts "[POLICY] Your message is not formatted correctly"
  exit 1
end

用法:

$ git ci -m "berlin|120"
[POLICY] Your message is not formatted correctly
$ git ci -m "london|120|XX"    
[POLICY] Your message is not formatted correctly
$ git ci -m "london|120|Looks good."    
[master 853e622] london|120|Looks good.
