Git:如何在预提交挂钩中重新暂存已暂存的文件 [英] Git: How to re-stage the staged files in a pre-commit hook

问题描述

我正在写一个git pre-commit钩子.
该脚本可以重新格式化某些代码，因此可以修改暂存的文件.

I'm writting a git pre-commit hook.
The script could reformat some code, so it could modify the staged files.

如何重新暂存已暂存的所有文件?

How can I re-stage all files that are already staged ?

推荐答案

在没有pre-commit hook上下文的情况下，您可以

Without the pre-commit hook context, you can get a list of the staged files with the following command:

git diff --name-only --cached

因此，如果要重新索引已暂存的文件，可以使用:

So if you want to re-index the staged files, you can use:

git diff --name-only --cached | xargs -l git add

在pre-commit hook上下文中，您应该遵循大卫·温特伯顿(David Winterbottom)的建议，并在未进行任何其他更改之前隐瞒了未进行的更改.

---

In the pre-commit hook context, you should follow the advices of David Winterbottom and stash unstaged changes before anything else.

此技术使您不必担心索引或更改未上演的更改. 因此，您不必暂存所有已暂存的文件，而不必暂存所有已更新的文件:

This technique allows you not to be worry about indexing, or alterate, a change that was not staged. So you don't have to stage all the staged files, but all the updated files:

# Stash unstaged changes
git stash -q --keep-index

# Edit your project files here
...

# Stage updated files
git add -u

# Re-apply original unstaged changes
git stash pop -q
