## What it is
ble.sh (Bash Line Editor) is a line editor written in pure Bash that replaces GNU Readline in interactive Bash sessions. It provides syntax highlighting, auto suggestions, enhanced auto-completion, and vim modes for the Bash command line.

## Use cases
- add syntax highlighting to my bash shell
- fish-like auto suggestions in bash
- enable vim mode in bash interactive shell
- replace readline with a better bash line editor
- improve bash tab completion
- customize my bashrc with a better prompt editor

## When to choose
- you use Bash interactively and want fish-like features such as syntax highlighting and auto suggestions
- you want vim editing modes or richer completion in Bash without switching shells
- you need a pure-Bash solution with no compiled binaries

## When to avoid
- you use zsh or fish rather than Bash
- you only need non-interactive scripting enhancements
- you cannot tolerate any shell startup latency from loading a large script
