NAME

Grammar::Editor - Interactive TUI for experimenting with Raku grammars

SYNOPSIS

# Run the TUI application
raku -I. bin/grammar-editor.raku

# Use as a library (module is a placeholder for future API)
use Grammar::Editor;

DESCRIPTION

Grammar::Editor is a terminal-based interactive tool for exploring and debugging Raku grammar rules. It provides a split-panel TUI where you can:

• Write grammar rules in an editor panel

• Type test input to parse against your grammar

• See a visual trace of which rules matched and which failed

• View the full match tree with captured values

The application uses Selkie::UI for the terminal interface and Grammar::Extractor for introspecting rule matching during parsing.

USAGE

The main entry point is the bin/grammar-editor.raku script. Run it from the project root:

raku -I. bin/grammar-editor.raku

The interface has four toggleable panels:

• Grammar — Edit your grammar rules

• Input — Enter test strings to parse

• Trace — Step-by-step rule matching trace

• Match — Full parse tree with matches
