git预提交钩子代码格式与部分提交？ [英] git pre-commit hook code formatting with partial commit?

问题描述

有没有一种方法来预先提交钩子自动格式化的代码（对于
例如 astyle ），但不是 / em>销毁部分提交？

工作流程：

 ＃编辑一个file.txt 
 git add -p file.txt 
＃添加一个块，但不是另一个
 
 git commit -m'一条消息'
 [PRE_COMMIT_HOOK ]格式化源代码
 
 git status 
＃另一个块尚未添加
  

我的问题是，如果你在脚本格式化之前需要
的pre-commit钩子内执行 git add 源代码，也添加了另一个块，
。但是我不希望那样。

有没有办法实现这个目的？

解决方案

我会用低级别的plumbing命令来做这件事，我的第一次尝试是沿着

  git ls-files --stage \ * .c |同时读取模式对象的舞台路径; 
 
 
 
 $ b $ format $ = $ g $ show $ object |缩进| git hash-object -w --stdin` 
 git update-index --cacheinfo $ mode $ formatted$ path
 ;; 
 esac 
完成
  

为避免冗余处理，请从 git diff-index --name-only --diff-filter = AM 输出为@torek建议。

is there a way to have a pre-commit hook which auto-formats the code (for example with astyle) but does not destroy a partial commit?

Workflow:

# edit a file.txt
git add -p file.txt
# add one chunk, but not another

git commit -m 'a message'
[PRE_COMMIT_HOOK] Formatting source code

git status
# the "another" chunk is still not added

My problem is, that if you do a git add inside the pre-commit hook, which is required after the script formatted the source code, adds the "another" chunk, too. But I don't want that.

Is there a way to achieve this?

解决方案

I'd do this by doing the work with the low-level "plumbing" commands, my first attempt would be something along the lines of

git ls-files --stage \*.c | while read mode object stage path; do
case $mode in
10*)
      formatted=`git show $object | indent | git hash-object -w --stdin`
      git update-index --cacheinfo $mode $formatted "$path"
;;
esac
done

To avoid redundant processing, start from git diff-index --name-only --diff-filter=AM output as @torek suggests.
