This repository contains Python implementations of the interpreters described in Samuel Kamin's excellent PLIBA [1] book.

Python examples

Examples designed to make it easier to understand the essentials of an interpreter.

SimpleCalc: single-module arithmetic expressions calculator.
Calculator: arithmetic expressions calculator with separate parser and evaluator.
CalcWithVars: arithmetic expressions calculator with variables.

Kamin's "chapter 1 language", minimal yet Turing-complete, inspired by Pascal with s-expression syntax. SubPascal is our name for it.

SubPascalWithoutFunc: SubPascal without function definitions.
SubPascalHappyPaths: "complete" SubPascal language, with function definitions but almost no error handling and limited REPL.
SubPascal: complete SubPascal with better error handling, multi-line REPL and source file execution.
