AlexScript is an interpreted, general-purpose scripting language with entire syntax in Polish: keywords, standard library, and error messages included. You write jesli, funkcja and klasa instead of if, function and class. It's dynamically typed and object-oriented, drawing on Ruby and JavaScript, and it's implemented from scratch in Ruby as a tree-walking interpreter (lexer, parser, AST, evaluator).
Distributed via source, Homebrew and Docker:
brew tap N3BCKN/alexscript
brew install alexscript
