Introduction

This program visualizes EBNF (Extended Backus Naur Form) grammar rules as syntax diagrams. A text file with the suffix .ebnf is required, which contains grammar rules written in EBNF. The program parses the rules, visualizes them in form of syntax diagrams and is able to generate .gif files for further use (e.g. in Word or on Web pages). Furthermore the program allows users to manipulate the look and the layout of the generated syntax diagrams.

the visualizer transforms it into the following syntax diagram

Simple example
