Mac 配置代码高亮 Git状态显示

摘要：首先进入到到目录一般默认打开的都是，如果不是输入回车即可，编辑目录下的编辑配置代码如下复制粘贴退出保存，然后执行一下回车即可。然后我们在来开启代码高亮开关，编辑开启配置项代码高亮开启文件内容行号保存退出就可以了。

Mac 一个为开发者量身定做的笔记本，相信你已经装好了iTerm2了，打开你的iTerm2开始我们的配置。文章来源于个人博客 YANGXIANGMING。分享给大家希望能帮助大家配置一个好的开发环境，好的开发环境才有好的心情Code。

首先进入到Home到目录一般默认打开的都是Home，如果不是输入 cd ~ 回车即可，编辑Home目录下的 .bash_profile 编辑 vim .bash_profile 配置代码如下：

#Git branch status
function git_status {
  local unknown untracked stash clean ahead behind staged dirty diverged
  unknown="0;34" # blue
  untracked="0;32" # green
  stash="0;32" # green
  clean="0;32" # green
  ahead="0;33" # yellow
  behind="0;33" # yellow
  staged="0;96" # cyan
  dirty="0;31" # red
  diverged="0;31" # red

  if [[ $TERM = *256color ]]; then
    unknown="38;5;20" # dark blue
    untracked="38;5;76" # mid lime-green
    stash="38;5;76" # mid lime-green
    clean="38;5;82" # brighter green
    ahead="38;5;226" # bright yellow
    behind="38;5;142" # darker yellow-orange
    staged="38;5;214" # orangey yellow
    dirty="38;5;202" # orange
    diverged="38;5;196" # red
  fi

  branch=$(git rev-parse --abbrev-ref HEAD 2>/dev/null)
  if [[ -n "$branch" ]]; then
    if [[ "$branch" == "HEAD" ]]; then
      branch=$(git rev-parse --short HEAD 2>/dev/null)
    fi
    git_status=$(git status 2> /dev/null)
    # If nothing changes the color, we can spot unhandled cases.
    color=$unknown
    if [[ $git_status =~ "Untracked files" ]]; then
      color=$untracked
      branch="${branch}+"
    fi
    if git stash show &>/dev/null; then
      color=$stash
      branch="${branch}*"
    fi
    if [[ $git_status =~ "working directory clean" ]]; then
      color=$clean
    fi
    if [[ $git_status =~ "Your branch is ahead" ]]; then
      color=$ahead
      branch="${branch}"
    fi
    if [[ $git_status =~ "Your branch is behind" ]]; then
      color=$behind
      branch="${branch}"
    fi
    if [[ $git_status =~ "Changes to be committed" ]]; then
      color=$staged
    fi
    if [[ $git_status =~ "Changed but not updated" ||
          $git_status =~ "Changes not staged"      ||
          $git_status =~ "Unmerged paths" ]]; then
      color=$dirty
    fi
    if [[ $git_status =~ "Your branch".+diverged ]]; then
      color=$diverged
      branch="${branch}!"
    fi
    printf "33[%sm%s33[0m" "$color" "($branch)"
  fi
  return 0
}

#bles colorin the terminal bash shell export
export CLICOLOR=1

#sets up thecolor scheme for list export
export LSCOLORS=gxfxcxdxbxegedabagacad

#sets up theprompt color (currently a green similar to linux terminal)
export PS1="[33[01;32m]u@h[33[00m]:[33[01;36m]w[33[01;31m]$(git_status)[33[0m]$ "

#enables colorfor iTerm
export TERM=xterm-256color

复制粘贴退出保存，然后执行一下 source .bash_profile 回车即可。然后我们在来开启代码高亮开关，编辑 vim .vimrc 开启配置项

#代码高亮开启
syntax on

#文件内容行号
set nu

保存退出就可以了。为了确保下次开机命令依然有效，执行如下命令：

echo "[ -r ~/.bashrc ] && source ~/.bashrc" >> .bash_profile

退出iTerm2重新打开就可以了，开始你的屌屌屌命令行高亮之旅吧！
