mac bash上显示git分支与状态

Posted 2022-01-20 yiyi17

　

主要实现

• 显示当前路径
• 显示当前所在分支
• 显示当前修改状态
  • = 表示一个干净的分支
  • ~ 表示文件有改动
  • # 表示已commit 但未 push

　

通过网上搜索和自己根据实际需要修改的代码如下:

.bash_profile

function parse_git_dirty 
    local git_status=$(git status 2> /dev/null | tail -n1) || $(git status 2> /dev/null | head -n 2 | tail -n1);
    local git_now;
    if [[ "$git_status" != "" ]]; then
        #local git_now; # 标示
	#echo "$git_status"
        if [[ "$git_status" =~ nothing\\ to\\ commit || "$git_status" =~  Your\\ branch\\ is\\ up\\-to\\-date\\ with ]]; then
            git_now="=";
        elif [[ "$git_status" =~ no\\ changes\\ added\\ to\\ commit ]]; then
            git_now=‘~‘;
       # elif [[ "$git_status" =~ Changes\\ to\\ be\\ committed ]]; then #Changes to be committed
        #    git_now=‘*‘;
       # elif [[ "$git_status" =~ Untracked\\ files ]]; then
        #    git_now="+";
       # elif [[ "$git_status" =~ Your\\ branch\\ is\\ up\\-to\\-date\\ with ]]; then
        #    git_now="#";
        fi
       # echo "$git_now";
    elif [[ "$git_status" = "" ]]; then
	git_now="#";
    fi
   echo "$git_now"



function git_branch 
    ref=$(git symbolic-ref HEAD 2> /dev/null) || return;
    echo "("$ref#refs/heads/") ";
