Pyret is built by the PLT group at Brown University in Providence, RI, USA. The group blog is a good resource for understanding its (recent) research. Pyret’s design and development draw on the group’s experience in programming languages, education, web security, user interfaces, and more.
John Ericson and Cody Mello were a great help with many final details of the build system, testing, and documentation.
The work of Danny Yoo on Moby, WeScheme, and Whalesong has been indispensible in both for inspiration and for re-use of image and bignum libraries.
Justin Pombrio, Liam Elberty, Kathi Fisler, Emmanuel Schanzer, Emma Youndtsmith, and Jonah Kagan have voluntarily used Pyret and given tons of valuable feedback while tolerating bugs and inconsistencies.
The students of Brown’s CSCI 0190, CSCI 1729, and CSCI 1730 had Pyret thrust upon them, and bore it with grace.
