Display Git dirty state and branch in terminal

每次在终端切换到项目目录，判断是否又文件修改&在哪个分支下面都要用git status来判断，为了避免这些麻烦做了个shell函数，可以直接在提示符中显示。

添加如下shell代码到~/.bash_profile

# http://timtang.me/blog/2013/02/03/show-git-state-branch/
function parse_git_dirty {
      [[ $(git status 2> /dev/null | tail -n1) != "nothing to commit (working directory clean)" ]] && echo "*"
}

function parse_git_branch {
      git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e "s/* \(.*\)/[\1$(parse_git_dirty)]/"
}

# 距离计算上一次提交的时间
function git_since_last_commit {
    now=`date +%s`;
    last_commit=$(git log --pretty=format:%at -1 2> /dev/null) || return;
    seconds_since_last_commit=$((now-last_commit));
    minutes_since_last_commit=$((seconds_since_last_commit/60));
    hours_since_last_commit=$((minutes_since_last_commit/60));
    minutes_since_last_commit=$((minutes_since_last_commit%60));
    echo "${hours_since_last_commit}h${minutes_since_last_commit}m ";
}

# PS1 设置
PS1="[\[\033[1;32m\]\u@\h:\w\[\033[0m] \[\033[0m\]\[\033[1;36m\]\$(parse_git_branch)\[\033[0;33m\]\$(git_since_last_commit)\[\033[0m\]$ "

别忘了source ~/.bash_profile, 这里是我使用的.bash_profile

好了看下结果：

[timtang@Tims-MacBook-Air:~/Documents/tim-tang.github.com] [master*]25h9m $

一点小技巧希望能帮你在开发的时候少敲几个命令，Cheers!
