预推Git挂钩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预推钩针对分支名称测试正则表达式。我已经阅读了预推文档，但是我无法将钩子插入到我的应用程序中。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。我也不确定你为什么执行^[a-z0-9-]+$并将结果存储在valid_chars中。尽管如此：

• 你可能想用一个错误来退出，如果分支名称不匹配正则表达式
• 您缺少valid_chars一个$前缀测试
• if [[ "$local_branch" =~ valid_chars]]; then应该有内部的空间]]

一如往常，确保脚本是.git/hooks/pre-push下，正确命名，并被标记为可执行文件。

我下面的作品（我已经离开了，因为我很懒样品钩评论）：

#!/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 =~ $valid_chars ]] 
then 
    echo "$message" 
    exit 1 
fi 

exit 0
