Szenario:在使用git进行文件提交时,我想在预提交挂钩内检查某条线是否已被修改。因此,我想比较修改后的文件中的部分行与存储库中相应的linepart。
后台:我想确保要提交的文件的版本号不是存储库中已有的文件。应强制用户为文件提供适当的版本号。这里不能自动增加提交时的版本号,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:是否可以在预提交挂钩中访问已修改的文件内容以及存储库文件?
答案 0 :(得分:5)
答案是肯定的。
但是 - pre commit hook
是一个客户端钩子,可以删除o删除,这就是为什么用服务器端钩子做它更好
这是一个示例钩子,用于检查是否修改了所需的文件。 一旦你知道文件是否已提交,请使用:
# 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 hook
#!/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>
