PLZoo (Programming Languages Zoo)

It is a good starting point for those who would like to implement their own programming language, or just learn how it is done. The following features are demonstrated:

functional, declarative, object-oriented, and procedural languages
source code parsing with a parser generator
recoding of source code positions
pretty-printing of values
interactive shell (REPL) and non-interactive file processing
untyped, statically and dynamically typed languages
type checking and type inference
subtyping, parametric polymorphism, and other kinds of type systems
eager and lazy evaluation strategies
recursive definitions
exceptions
interpreters and compilers
abstract machine

The languages are not really meant to be used. Rather, you should read and study the source code, which is decorated with ample comments. Also, each language lang has its own README.markdown and example.lang in the subdirectory src/lang. Nevertheless, all the language are fully functioning miniature versions of real languages and can be executed.

PLZoo (Programming Languages Zoo)

The Programming Languages Zoo is a collection of miniature programming languages which demonstrates various concepts and techniques used in programming language design and implementation.
