某天闲得无聊想要通过 powershell 的脚本修改 powershell 的提示符，让 idea 的终端显示更加鲜艳简洁，最终做到如下效果
- 修改提示符颜色
- 修改提示符提示普通用户和管理员权限
- 修改路径表现形式
- 修改项目根路径以 ~ 表示
这是以管理员形式启动的idea，这时候终端是有管理员权限的，所以样式被改变了
实现流程
- 创建一个
ztp_function_idea.ps1文件（该文件需要在配置在环境变量，如果没有则需要使用的时候键入完整路径）
function prompt {
$dir = (get-location).path;
if ($null -eq $env:work) {
$env:work = $dir
}
$name = $env:username.tolower()
# 定义路径映射：每个元素是路径表达式和对应简称的元组

@{
# personal 文件夹且不等于 mydocuments（避免重复）

alias = 'documents'
