PSReadLine
PSReadLine is a command line editor for PowerShell that provides advanced line editing and command history management. It functions as a suite of tools for enhancing the interactive shell experience through a Bash-inspired implementation of editing, completion, mapping, synchronization, and highlighting.
The project includes an interactive completion engine for navigating suggestions via a menu system and a keyboard mapping tool for assigning shortcuts to custom actions. It also features a session history synchronizer that automatically saves and shares command history across multiple active terminal sessions, alongside a syntax highlighter that applies color to command line text based on language patterns.
The system covers a broad range of user interface enhancements, including multi-line input editing, interactive history search, and token-based cursor navigation. It further manages text buffers to support undo and redo operations for command line text manipulation.
