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.
http://www.linuxquestions.org/questi...wsally-615861/
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.

[Note that we can link OR include...

Playing with parsing

Today's features:

Creating an extensible mid-level parser that makes sense in C.
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...

The simplest yet, I think.. at least the C program is.

Features:

tips on how to find C/C++ header paths and declarations
tips on how to find libs containing references and definitions
a super-simple program to demangle C++ names

----------------
Note: With even a simple automatic makefile generator such as the one built from sources in this blog (

Simple C: Filling in the blanks - A simple memory allocator/reallocator.

No memdup()? No memcat()? No prob.

Today's Features:

Simple C/C++ program and new memdup() and memcat() functions.
C macros (spanning lines with backslash) to create 'lenient' aliases.
Type casting in C/C++ to override sometimes overly strict syntax checks.

Anyone that has used strdup() or strcat() knows how convenient those are. But when it comes to memory allocation and reallocation for other kinds of data the lack of simple standard mechanisms for this often leads to duplicated...
