Git Push 上的 JSHint（更新挂钩）

Question

当客户端推送到远程 git 存储库（裸机）时，我想要一个钩子，它可以在传入的更改文件上自动运行 JSHint，并在 JSHint 返回错误时拒绝提交。我只关心确保主分支符合我们的 JSHint 配置。所以我有这个脚本：

#!/bin/bash

# --- Command line
refname="$1"
oldrev="$2"
newrev="$3"
branch=${refname#refs/heads/}

echo ${refname}
echo ${oldrev}
echo ${newrev}
echo ${branch}

if [ "$branch" == "master" ]
then
  echo "Need to JSHint" >&2
  exit 1
fi

# Not updating master
exit 0

我想我有两个问题：

1. 如何获取推送中更改的文件列表？
2. 如何将这些文件传递给 JSHint？

Answer 1

我不相信这是完成任务的最佳方式。基本上，代码在 repo 中生成每个 JavaScript 文件的文件，然后分别调用 JSHint。奖励它实际上使用项目的 .jshintrc 文件（如果存在）。 Also on Gist

任何建议、指针、替代方案？？？

#!/bin/bash

# --- Command line
refname="$1"
oldrev="$2"
newrev="$3"
branch=${refname#refs/heads/}

# Make a temp directory for writing the .jshintrc file
TMP_DIR=`mktemp -d`
EXIT_CODE=0

# If commit was on the master branch
if [ "$branch" == "master" ]
then
  # See if the git repo has a .jshintrc file
  JSHINTRC=`git ls-tree --full-tree --name-only -r HEAD -- | egrep .jshintrc`

  JSHINT="jshint"
  if [ -n "$JSHINTRC" ]
  then
    # Create a path to a temp .jshintrc file
    JSHINTRC_FILE="$TMP_DIR/`basename \"$JSHINTRC\"`"

    # Write the repo file to the temp location
    git cat-file blob HEAD:$JSHINTRC > $JSHINTRC_FILE

    # Update the JSHint command to use the configuration file
    JSHINT="$JSHINT --config=$JSHINTRC_TMP_DIR/$JSHINTRC"
  fi

  # Check all of the .js files
  for FILE in `git ls-tree --full-tree --name-only -r ${newrev} -- | egrep *.js`; do
    FILE_PATH=`dirname ${FILE}`
    FULL_PATH=${TMP_DIR}/${FILE_PATH}
    mkdir -p ${FULL_PATH}
    git cat-file blob ${newrev}:${FILE} > "$TMP_DIR/$FILE"
    ${JSHINT} ${TMP_DIR}/${FILE} >&2
    # Exit status of last command
    EXIT_CODE=$((${EXIT_CODE} + $?))
    if [[ $EXIT_CODE -ne 0 ]]
    then
      rm -rf ${TMP_DIR}
      exit $EXIT_CODE
    fi
  done
  rm -rf ${TMP_DIR}
fi

# Not updating master
exit 0
