CompilerKit Introduction

CompilerKit is a small toolkit used to build recursive-descent parsers and compilers. There are four main parts to CompilerKit, each discussed and documented on their own page:

• Scanner, which is used to build the lexical analysis portion of your compiler;
• Parser, and the derived RecoveringParser, which are used to build recursive descent parsers;
• Sema, which provides tools to build the semantic analysis portion of your compiler;
• and Codegen, an artifact generator that lets you emit small programs that run in a simplistic virtual machine.

There are also some ancillary modules that are used throughout the source:

• Token defines a source token type, which encodes text, a type and a location;
• Error defines an error type and convenience functions to report them;
• Program defines a simplistic machine language and lets you emit and run programs in a basic virtual machine runtime.
