Overview

Luma is a macro system for the Lua language that is heavily inspired by Scheme's define-syntax/syntax-rules system. The Scheme macro system uses pattern matching to analyze the syntax of a macro, and template substitution to build the code that the macro expands to. This is a powerful yet simple system that builds on top of Scheme's structural regularity (the use of S-expressions for all code).

Luma also separates the expansion process in pattern matching and template substitution phases, but as Lua source is unstructured text the pattern and template languages have to work with text. Luma uses LPEG for pattern matching and Cosmo for templates.

Status

This is the second public release of Luma, version 0.2. It just updates Luma to work with the current version of LPEG, 0.10 (Luma 0.1 used LPEG 0.7).
