git hooks

钩子都被存储在 Git 目录下的 hooks 子目录中, 即绝大部分项目中的 .git/hooks 文件夹下

# An example hook script to verify what is about to be committed.

Error: Attempt to add a non-ASCII file name.

This can cause problems if you want to work with people on other platforms.

To be portable it is advisable to rename the file.

If you know what you are doing you can disable this check using:

  git config hooks.allownonascii true
EOF
        exit 1
fi

# If there are whitespace errors, print the offending file names and fail.
exec git diff-index --check --cached $against --

必须使用无扩展名的 pre-commit 脚本文件名,不然 git 不知道扩展名是什么!

脚本内部可以指定不同的脚本执行环境,如 Perl, Python 等

??? js script / Node.js script ??? ❓

👻为什么 git 不可以忽略扩展名,因为 .sample 文件名也相同,无法区分出来!

git hook 的脚本不能使用扩展名
