This semester at University, I’m taking ‘Compiler Design & Techniques’ as a module. The second coursework involves drawing Finite State Machines diagrams that represent regular expressions. Rather than using a word processor to draw these diagrams with a rather untidy look about them, I went in search of a tool that’d help me produce high quality drawings. I’d heard that Latex was good for mathematical diagrams, but that seemed like overkill as I only wanted the diagrams, not a whole new document syntax to learn.
