META II

me studying compiler writing languages with META II

Source

Meta II that is being compiled to Racket(Scheme) script.

File	Contents
`meta.rkt`	Helper module mainly with i/o procedures
`meta3l.m3l`	First version written in its own language
`meta3r.m3r`	Improved/optimized version written in its own language
`meta3l.rkt`	My first meta3 compiler written by hand
`o_meta3l.rkt`	First version compiled itself
`o_meta3r.rkt`	Better version compiled itself

Meta II with virtual machine simulating one from the paper

File	Contents
`meta2vm.py`	My own Meta II virtual machine
`meta2compile.py`	My own compiler for META II language (using sly lex/yacc)
`meta2.m2asm`	Python compiler output for `meta2.meta2`
`meta2.meta2`	Original "META II written in its own language"
`test.m2asm`	Output of META II (compiled by python) compiling itself in vm

My Meta 3 is compiler writing language thats being compiled to standalone python code keeping syntax very close to original META II syntax

transitioned from meta2 to meta3 with something like:

./meta2vm.py meta2 meta3.meta2 meta3.m2asm
./meta2vm.py meta3 meta3.meta3 meta3.py
python meta3.py meta3.meta3 > meta3m.py

File	Contents
`meta3.meta2`	Meta 3 compiler written in META II language
`meta3.m2asm`	Meta 3 compiler compiled for meta2vm
`meta3.meta3`	Meta 3 written in its own language
`meta3.py`	Meta 3 compiled with META II runnning `meta3.m2asm`
`meta3m.py`	Meta 3 compiled itself
