场景: 在使用git提交文件时,我想要在pre-commit hook中检查某一行是否已被修改。因此,我希望将修改后的文件中的某些部分与存储库中的相应部分进行比较。
背景: 我想要确保要提交的文件具有不同于已在存储库中的文件的版本号。用户应该强制为文件提供适当的版本号。自动增加版本号不是一个选项,因为我们使用多部分版本(1.0.0.0),用户必须修改版本字符串的正确部分...
问题: 在pre-commit hook中是否可以访问修改后的文件和存储库文件的文件内容?
# you have the commit id so you can checkout the given file
git show <commit id>:<full path to file>
完整的示例代码:
pre-receive钩子
#!/bin/sh
# Check to see if this is the first commit in the repository or not
if git rev-parse --verify HEAD >/dev/null 2>&1
then
# We compare our changes against the previous commit
against=HEAD^
else
# Initial commit: diff against an empty tree object
against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi
# Redirect output to screen.
exec 1>&2
# Check to see if we have updated the given file
if [ $(git diff-tree -r --name-only $against | grep <ANY FILE YOU WANT TO FIND OUT HERE> ) ];
then
# you have the commit id so you can checkout the given file
# the commit is: git rev-parse HEAD
git show <commit id>:<full path to file>
# personal touch :-)
