Git

Git是一套版本控制系统（VCS）。

Hook

Hook是针对某些行为的操作（通常包括了pre-以及post-），可以设计一些pre-hook在本地端挡住常见的错误行为。

范例

禁止在develop下直接commit，在.git/hooks/pre-commit里面设定：

#!/bin/bash

if [[ "$(git rev-parse --abbrev-ref HEAD)" = "develop" ]]; then
    echo "You cannot commit directly to the develop branch."
    exit 1
fi

禁止develop从其他branch rebase更新，但允许origin/develop，在.git/hooks/pre-rebase里面设定：

#!/bin/bash

# $1: source branch.
# $2: destination branch (empty if it's current branch).

if [[ "$2" = "develop" || ( "$2" = "" && "$(git rev-parse --abbrev-ref HEAD)" = "develop" ) ]]; then
    if [[ "$1" = "origin/develop" ]]; then
        # OK
        exit 0
    fi

    echo "You cannot rebase develop branch from branch other than origin/develop."
    exit 1
fi

Global

可以在.gitconfig将整包专案设定自定义的hooksPath，把上面提到的hook files（像是pre-commit或是pre-rebase）放到指定的目录就可以了：

[core]
    hooksPath = ~/git/work/hooks

除了全域设定以外，也可以搭配includeIf变成区域设定，只针对某些目录下的专案使用特定的hook：

[includeIf "gitdir:~/git/work"]
    path = ~/git/work/.gitconfig
