使用git计算24小时内提交的+未提交的LOC更改

尝试这些更改。我相信这段代码可以优化:)

loc_changed() {

    since=${1:-24 hours}
    author=${2:-your_email@gmail.com}

    stagedPlus=$(git log --numstat --pretty="%H" --author="$author" --since="$since" | awk 'NF==3 {plus+=$1} END {print plus}') 

    unstagedPlus=$(git diff  $(git log -1 --pretty="%H" | tail -1) --numstat | awk 'NF==3 {plus+=$1} END {print plus}')

    stagedMinus=$(git log --numstat --pretty="%H" --author="$author" --since="$since" | awk 'NF==3 {minus+=$2} END {print minus}') 

    unstagedMinus=$(git diff  $(git log -1 --pretty="%H" | tail -1) --numstat | awk 'NF==3 {minus+=$2} END {print minus}')

    if [[ -z $unstagedPlus ]]; then
        unstagedPlus=0
    fi
    if [[ -z $unstagedMinus ]]; then
        unstagedMinus=0
    fi

    print "+$(($stagedPlus+$unstagedPlus)), -$(($stagedMinus+$unstagedMinus))"
}

diff numstat )从上次提交到当前未老化代码。
