# Graphomaton [](https://badge.fury.io/rb/graphomaton) [](https://github.com/ydah/graphomaton/actions/workflows/ci.yml)
A tiny Ruby library for generating finite state machine (automaton) diagrams as SVG.
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'graphomaton'
```
And then execute:
```bash
bundle install
```
Or install it yourself as:
```bash
gem install graphomaton
```
## Usage
```ruby
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')
```
