git - 预推 Git 钩子(Hook)以确定分支名称是否有效

Question

我想编写一个 Bash 脚本来使用 Git 预推送 Hook 针对分支名称测试正则表达式。我已阅读推送前文档，但无法将钩子(Hook)插入我的应用程序。任何人有任何建议。

local_branch = $(git rev-parse --abbrev-ref HEAD)
valid_chars = $(^[a-z0-9-]+$)

if [[ "$local_branch" =~ valid_chars]]; then
  echo 'Failed to push.  Branch is using incorrect characters.  Valid        Characters are lower case (a-z), numbers (0-9) and dashes(-).  Please rename branch to continue'
  exit 1
fi

exit 0

运行上面的脚本会导致各种错误。我也不确定您为什么要执行 ^[a-z0-9-]+$ 并将结果存储在 valid_chars 中。尽管如此:

• 如果分支名称与正则表达式不匹配，您可能希望退出并报错
• 您在测试中缺少 valid_chars 的 $ 前缀
• if [[ "$local_branch"=~ valid_chars]];那么应该在]]
里面有一个空格

一如既往，确保脚本在 .git/hooks/pre-push 下，正确命名，并标记为可执行。

以下对我有用(因为我很懒，我留下了示例钩子(Hook)评论):

#!/bin/bash

# An example hook script to verify what is about to be pushed.  Called by "git
# push" after it has checked the remote status, but before anything has been
# pushed.  If this script exits with a non-zero status nothing will be pushed.
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# If pushing without using a named remote those arguments will be equal.
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
#   <local ref> <local sha1> <remote ref> <remote sha1>
#
# This sample shows how to prevent push of commits where the log message starts
# with "WIP" (work in progress).

local_branch="$(git rev-parse --abbrev-ref HEAD)"
valid_chars="^[a-z0-9-]+$"
message='...'

if [[ ! $local_branch =~ $valid_chars ]]
then
    printf '%s\n' "$message"
    exit 1
fi

exit 0
