PowerShell PSReadLine特性

以前配置完VSCode和PowerShell集成後，可使用powershell的智能感知，高亮等功能，查了一下，這個應該跟PSReadLine有關係。PSReadLine在PowerShell控制檯中提供了改進的命令行編輯體驗。

PSReadLine須要PowerShell 3.0或更高版本以及控制檯主機。它在PowerShell ISE中不起做用。它在Visual Studio Code的控制檯中工做。

PSReadLine provides a powerful command line editing experience for the PowerShell console. It provides:

Syntax coloring of the command line
A visual indication of syntax errors
A better multi-line experience (both editing and history)
Customizable key bindings
Cmd and Emacs modes
Many configuration options
Bash style completion (optional in Cmd mode, default in Emacs mode)
Emacs yank/kill ring
PowerShell token based "word" movement and kill
