PowerShell/PSReadLine
PSReadLine
PSReadLine is a command line editor, completion engine, history manager, and syntax highlighter for the PowerShell console. It provides a bash-inspired line editing experience that enables advanced cursor movement and text manipulation within the terminal.
The project features a customizable input mapper for assigning keyboard shortcuts to specific actions and navigation logic. It includes a completion system that suggests matching commands through selectable menus or prefix-based matching.
The tool covers real-time color coding for command text and error notifications to improve readability. It manages the automatic persistence and retrieval of command history, allowing for interactive searching and filtering of previous entries. It also supports multi-line input editing and token-based cursor navigation.
