PLT Games

PLT Games was a monthly competition to design a programming language, that took place seven times starting in December 2012. It received 67 submissions, many of which are worthy of review.

Competitions

• Into the Turing Tarpit (December 2012)
• Testing the Waters (January 2013)
• Game on (February 2013)
• Do it Live (March 2013)
• Only Syntax (April 2013)
• Replace PHP (May 2013)
• Obscure Security Language (September 2013)

Criteria

• Innovation: Does this language introduce you to any new concepts? Does this seem like a unique language?
• Completeness: Does the implementation of this language work as intended? Does it lack many bugs?
• Theme application: Does the language fit the theme? Does it satisfy the constraints in the description?

My favorites

• Leaf by Callum Rogers uses only one binary tree, with operations to manipulate it. [tutorial] [playground] [my implementation]
• Cratylus by Pablo Barenbaum is a polynomial rewriting esolang, that is a superset of Conway’s FRACTRAN.
• Eightfold by Pablo Barenbaum is a dependently typed esolang.
• Myopia by Miikka Koskinen is based on µ-recursive functions.
• Vigil by Bob Nystrom enforces contracts by deleting offending functions from the source code.
• Turipong by Ryan Pavlik is a Befunge derivative inspired by Pong; however it has no user-controlled paddles.
