使用预提交搜索文件

pre-commit-hook grep terminal git

codingninja · 技术社区 · 10 年前

我正在尝试添加一个git预提交挂钩,它将检查所有已更改和新文件 TODO: 文本

我试过了

#!/bin/sh

. git-sh-setup  # for die 
git-diff-index -p -M --cached HEAD -- | grep '^+' |
grep TODO: && die Blocking commit because string TODO: detected in patch
:

我在一个类似的问题中看到了这一点,但没有运气。

是的,这个位在被暂存的文件上循环,但是不管它的哪个部分被暂存,它都会对整个文件进行grep!

   git diff --cached --name-only | \
       grep -E $FILES_PATTERN | \
       echo 'COMMIT REJECTED Found'  $i 'references. Please remove them before commiting' && exit 1

这不好——不要测试未暂存的字符串。

此解决方案 测试一个或多个FORBIDEN字符串 只有暂存代码,而不是整个文件 :

预先提交

#!/bin/bash

RESTORE='\033[0m'
RED='\033[00;31m'
YELLOW='\033[00;33m'
BLUE='\033[00;34m'

FORBIDDEN=( 'TODO:' 'DO NOT COMMIT' 'console.log' 'die' )
FOUND=''

for j in "${FORBIDDEN[@]}"
do
  for i in `git diff --cached --name-only`
  do

    # the trick is here...use `git show :file` to output what is staged
    # test it against each of the FORBIDDEN strings ($j)

    if echo `git show :$i` | grep -q "$j"; then

      FOUND+="${BLUE}$i ${RED}contains ${RESTORE}\"$j\"${RESTORE}\n"

    fi
  done
done

# if FOUND is not empty, REJECT the COMMIT
# PRINT the results (colorful-like)

if [[ ! -z $FOUND ]]; then
  printf "${YELLOW}COMMIT REJECTED\n"
  printf "$FOUND"
  exit 1
fi

# nothing found? let the commit happen
exit 0

首先,挂钩必须在 .git/hook 文件夹和名称 pre-commit (具有执行权: chmod +x .git/hooks/pre-commit )

这个 OP jesusjjf 确认 in the comments 这就是问题所在:

我复制了 pre-commit.sample 文件转换为纯文本文件,而不仅仅是重命名。

其次,下面是一些脚本示例:

You have another example 使用类似的技术,使用 git rev-parse 和 git diff-index ,以及 empty tree I mentioned before :

#!/bin/sh

if git rev-parse --verify HEAD >/dev/null 2>&1; then
    against=HEAD
else
    against=4b825dc642cb6eb9a060e54bf8d69288fbee4904
fi

for FILE in `git diff-index --name-status $against -- | cut -c3-` ; do
    # Check if the file contains 'debugger'
    if [ "grep 'debugger' $FILE" ]
    then
        echo $FILE ' contains debugger!'
        exit 1
    fi
done
exit

The comments on this gist 提及:

在我的系统中, if [ "grep 'debugger' $FILE" ] 始终计算为 true .
将其更改为 if grep -q 'debugger' "$FILE" 修复了这个问题。

A. more recent example :

#!/bin/bash

# Pre commit hook that prevents FORBIDDEN code from being commited.
# Add unwanted code to the FORBIDDEN array as necessary

FILES_PATTERN='\.(rb|js|coffee)(\..+)?$'
FORBIDDEN=( debugger ruby-debug )

for i in "${FORBIDDEN[@]}"
do
  git diff --cached --name-only| grep ".js" |xargs sed 's/ //g'|grep "ha_mobile.debug=true" && \
        echo 'COMMIT REJECTED Found ha_mobile.debug=true references. Please remove them before commiting' && exit 1

  git diff --cached --name-only | \
        grep -E $FILES_PATTERN | \
        GREP_COLOR='4;5;37;41' xargs grep --color --with-filename -n $i && \
        echo 'COMMIT REJECTED Found'  $i 'references. Please remove them before commiting' && exit 1
done

exit 0
