Ble.sh
ble.sh is a programmable line editor for Bash that provides syntax highlighting, auto-completion, and advanced text editing capabilities. It functions as a Bash syntax highlighter and command completion engine to enhance the standard shell input experience.
The project implements a Vim-inspired shell editor, bringing motions, visual modes, and macros to the command line. It further distinguishes itself with a system for text abbreviation expansion and a modal interaction system that toggles between insert and command modes.
The editor supports multiline command input and a dynamic suggestion system with navigable menus for completing commands and file paths. It also includes an event-driven hook system for shell workflow automation, allowing custom handlers to be bound to events such as directory changes or command execution.
Configuration options include editor variable customization and terminal appearance settings for syntax highlighting colors and unicode character widths.
