Meta, a straightforward compiler-compiler

This project is based on META-II by Val Schorre.

Meta generates C code implementing a parser/compiler for a EBNF-like grammar file.

Meta is written in itself so it needs to be bootstrapped from a C implementation. I provide meta.c so you just need to compile it.

Build and use

To bootstrap:

make meta

To compile a grammar in the same directory (for test purposes):

make grammar

To compile it directly:

./meta grammar.meta grammar.c
gcc grammar.c -o grammar

TODO

• Refactoring with literate programming
• More Wirth-like metasyntax
• Better command line interpreter
• Better error and warning messages
• Create useful grammar examples
• Create a demonstration compiler
