In order learn about the internals of programming languages, I developed a strongly-typed, interpreted language. FlannelScript uses JavaCC for parser generation with a custom lexer and runtime in Java.
GradientView
GradientView is an open-source Swift utility for easily creating views with gradient backgrounds. I found that I often re-wrote the code for iOS gradients, so I decided to create a dedicated open-source library.
