Parser Test 3 (A Return Stack & Compiler)

A self extractor for the 'lib' files that we include for this (pretty cute) little calculator are here.

Re: the compiler part. It's not much of a compiler, but it serves as a proof of concept. (It's used internally, the program is not compiled.)

Before we dig in here, I should say...

Bug in Parser Test 2.

Parser Test 1

See the previous blog entry: "Playing with parsing" here.

to grab the files we need to include for these tests and a working mc2 definitions file for those who have mc2. Type "mc2 -init" first time. After that "make update" will add/remove files from the makefile.

Looking at BNF-like syntax and C syntax similarities.
Tossing flex as far as we can throw it. While its still burning.

The file set here isn't 'finalized' in any way but it's been stable for a few days. These examples are therefor not about THIS set of functions but about parsing in general, although this file set will very likely be part of the mc2 parsing system...

drks' ParseConfig was not powerful enough for my needs.
Hans' parse_config was also not powerful enough for my needs.

So I rolled my own and offer it here for community use. I was delaying publishing because it is not finished (there are TODOs in the code) but it works well enough and may never be finished so better...
