我试图阻止 git 提交继续使用预提交 Hook 。通过阅读手册,当您返回 0 以外的退出代码时它应该停止。我正在测试 csscomb 命令是否返回错误,如果返回错误则中断循环并退出,但 git commit 仍在继续通过 git commit (-a)
输入消息。
我从 https://github.com/filtercake/git-pre-commit-csscomb fork 并修改了下面的脚本
#!/bin/bash
# pre-commit hook to comb staged .sass and .scss files
# save as .git/hooks/pre-commit
# make executable: chmod +x .git/hooks/pre-commit

最佳答案
git diff-index --cached --full-index --diff-filter=ACM $against | \
{
while read -r line; do
麻烦来了。多命令管道阶段在子 shell 中运行,并且该循环的导出退出其子 shell。子外壳也有自己的环境,因此您也不能从它们传递变量设置。
while read -r; do
if ! good $REPLY; then exit 1; fi
done <<EOD
$(git diff-index --cached --full-index --diff-filter=ACM $against)

关于macos - 使用 exit 在预提交 Hook 中停止 git commit,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/30609480/
