我可以替换提交消息git中的消息吗？

如何解决我可以替换提交消息git中的消息吗？

我在 git 中使用了 commit-msg 钩子来检查我的提交是否正确，并希望自动将 BugID 替换为 Bug 地址。但它似乎只能在提交消息的底部再添加一行，而不是替换原始行。有什么办法可以让它工作吗？ 我的提交模板是

Branch:
BugId:
Description:

这是我的代码：

with open(sys.argv[1],r+) as fp:
    lines=fp.readlines()
    for line in lines:
        if line[0]=="#":
            continue
        line=line.strip()
        for l in l.split('/n'):
            if not l.split(":")[-1]:
                print(l,"is empty")
                sys.exit(1)
            if l.startswith("Bug"):
                fp.write(l.replace(l.split(":")[-1],"http:bugs.xxxxxxxxx")
sys.exit(0)

解决方法

这是 Gerrit 的一个示例，如果它不存在，则向每个提交添加“Change-Id: ....”行

当然，它不是 Python，但我认为你可以从那里借用一个想法

if test "$#" != 1 ; then
  echo "$0 requires an argument."
  exit 1
fi

if test ! -f "$1" ; then
  echo "file does not exist: $1"
  exit 1
fi

if test ! -s "$1" ; then
  echo "file is empty: $1"
  exit 1
fi

# $RANDOM will be undefined if not using bash,so don't use set -u
random=$( (whoami ; hostname ; date; cat $1 ; echo $RANDOM) | git hash-object --stdin)
dest="$1.tmp.${random}"

# Avoid the --in-place option which only appeared in Git 2.8
# Avoid the --if-exists option which only appeared in Git 2.15
cat "$1" \
  | git -c trailer.ifexists=doNothing interpret-trailers --trailer "Change-Id: I${random}" > "${dest}" \
  && mv "${dest}" "$1"

注意脚本的最后几行：它创建一个 dest，然后打印消息并添加“Change-Id”（如果它不存在）。然后它将临时目标移动到实际成为消息。工作完成。

我对 git hooks 不是很精通，但这个应该在名为 .git/hooks/commit-msg 的文件中，所以我相信这就是你所需要的
