Live coding languages for quilters.
Barbara is a novel live coding interface that enables users to design languages for visual geometric pattern generation. Inspired by algorithmic quilting patterns, Barbara helps users construct languages that mimic real-world quilting procedures which can be used for both live coding performance or digital quilt recreation. Users create languages and patterns in Barbara’s online coding environment with the Parsing Expression Grammar language formalism; the resulting patterns can be freely shared, remixed, and combined into new quilts. As a push towards the applications of language-oriented design, we created Barbara to broaden access to the power of computational media and the beauty of quilting for both programmers and quilters alike. Barbara is free and open-source software.
