git - 在 git 提交范围内搜索文本

Question

我需要在过去 20 次 git 提交(或范围)中搜索文本“TEXT”
我需要查看匹配的文件名和行号。

注意:
我想搜索提交内容，但不像 git grep 那样在该提交上进行投影。
我所说的提交内容是指我可以使用 git diff HEAD^^^..HEAD

看到的内容

我得到的最接近的是使用 git log --raw -GTEXT，它向我显示提交内容中包含“TEXT”并显示文件名。但是仍然没有行号。

还有一些管道
git diff $(git log -n 20 --pretty=format:%h -GTEXT) | grep -E 'TEXT|\+\+\+|@@\s'

还是有些啰嗦，杂音多，如果有更好的解决办法，请回答。

获取最后 20 次提交:

git log -n 20

获取每个关联数组:

declare -A COMMITS # Declare associative array
COMMITNUMBER=0

while read -r line; do # For each line, do
    # Add 1 to COMMITNUMBER, if the current line contains "commit [0-9a-f]* (e.g., new associative array index for each commit)
    # As this'll happen straight way, our array is technically 1-indexed (starts from "${COMMITS[1]}", not "${COMMITS[0]}")
    REGEX="commit\s[0-9a-f]*"
    [[ "$line" =~ $REGEX ]] && COMMITNUMBER=$(( COMMITNUMBER+1 ))

    # Append the commit line to the index
    COMMITS[$COMMITNUMBER]="${COMMITS[$COMMITNUMBER]} $line"
done < <(git log -n 20)

然后迭代:

for i in "${!COMMITS[@]}"
do
  echo "key  : $i"
  echo "value: ${COMMITS[$i]}"
done

这给出了类似下面的输出:

key  : 1
value:  commit 778f88ec8ad4f454aa5085cd0c8d51441668207c Author: Nick <nick.bull@jgregan.co.uk> Date:   Sun Aug 7 11:43:24 2016 +0100  Second commit 
key  : 2
value:  commit a38cd7b2310038af180a548c03b086717d205a61 Author: Nick <nick.bull@jgregan.co.uk> Date:   Sun Aug 7 11:25:31 2016 +0100  Some commit

现在你可以使用 grep 或任何东西在循环中搜索每个，并匹配你需要的:

for i in "${!COMMITS[@]}"
do
    REGEX="Date:[\s]*Sun\sAug\7"
    if [[ "${COMMITS[$i]}" =~ $REGEX ]]; then
        echo "The following commit matched '$REGEX':"
        echo "${COMMITS[$i]}"
    fi
done

总计:

search_last_commits() {
    [[ -z "$1" ]] && echo "Arg #1: No search pattern specified" && return 1
    [[ -z "$2" ]] && echo "Arg #2: Number required for number of commits to return" && return 1

declare -A COMMITS # Declare associative array
COMMITNUMBER=0

    while read -r line; do # For each line, do
        # Add 1 to COMMITNUMBER, if the current line contains "commit [0-9a-f]* (e.g., new associative array index for each commit)
        # As this'll happen straight way, our array is technically 1-indexed (starts from "${COMMITS[1]}", not "${COMMITS[0]}")
        REGEX="commit\s[0-9a-f]*"
        [[ "$line" =~ $REGEX ]] && COMMITNUMBER=$(( COMMITNUMBER+1 ))

        # Append the commit line to the index
        COMMITS[$COMMITNUMBER]="${COMMITS[$COMMITNUMBER]} $line"
    done < <(git log -n $2)

    for i in "${!COMMITS[@]}"
    do
        REGEX="$1"
        if [[ "${COMMITS[$i]}" =~ $REGEX ]]; then
            echo "The following commit matched '$REGEX':"
            echo "${COMMITS[$i]}"
        fi
    done
}

编辑:

用法:

search_last_commits <search-term> <last-commits-quantity>

例子:

search_last_commits "Aug" 20
