From Curiosity to Confusion: My Journey of Creating Confuscript in Ruby
summary
Built a toy language called ConfuseScript that flips semantics: plus acts like minus, multiply like divide, and variables initialize with null while output uses the literal token console input. Implementation uses Ruby and the Treetop library with a parsing expression grammar to generate ASTs, node classes that evaluate against a hash-based context, and minimal evaluator logic so the whole thing fits a weekend project. Source is open source and ready to run and extend.
