Graphomaton

A tiny Ruby library for generating finite state machine (automaton) diagrams as SVG.

Installation

Add this line to your application's Gemfile:

gem 'graphomaton'

And then execute:

bundle install

Or install it yourself as:

gem install graphomaton

Usage

require 'graphomaton'

# Create a DFA that accepts strings ending with 'ab'
automaton = Graphomaton.new

# Add states
automaton.add_state('q0')
automaton.add_state('q1')
automaton.add_state('q2')

# Set initial and final states
automaton.set_initial('q0')
automaton.add_final('q2')

# Add transitions
automaton.add_transition('q0', 'q1', 'a')
automaton.add_transition('q1', 'q2', 'b')
automaton.add_transition('q0', 'q0', 'b')
automaton.add_transition('q1', 'q0', 'a')
automaton.add_transition('q2', 'q0', 'b')
automaton.add_transition('q2', 'q1', 'a')

# Save as SVG
automaton.save_svg('output.svg')
