mini-term in qt4.

Today's features:

A simple terminal-like application built from a qt4 class that can be used for other stuff too.
The present application can run shell commands and has copy/paste (ctrl-c, ctrl-v) capabilitity.
Another example of the Windows-like api so that C/C++ code can run in Qt4.
Runs the custom code (terminal in this case) inside a QT 'exec' loop... sorta. We call it 'run()'.

QT4 -- Having trouble with qInitResouces_<appname>() ?

Having trouble with qInitResouces_<appname>()?

Try this.

Code:

#ifdef Q_INIT_RESOURCE
#undef Q_INIT_RESOURCE
#endif

#define Q_INIT_RESOURCE(name) extern void qInitResources_##name()

The version of this macro in qglobal.h could never have ever worked.

If you enjoy digging into the low level stuff, I think you'll be amused by the context of this bug. ;-)

Simple C example for beginners and bug fix for libLQ-qt version 3.0.x

Simple C example for beginners and bug fix for libLQ-qt version 3.0.x

[v.3.0 (mc2 and libLQ) will no longer be the current version(s) but it still works and we have a bug fix here that applies to all 3.0.x versions.]

Today's feature:

A simple C/C++ example.
A converter from relative paths to absolute.
A bug fix for the libLQ-qt/mc2 3.0 d/load.

While 'canonicalize_file_name()' is great for paths that don't have macros in them, and for dereferencing symlinks,...

news, sorta

The new parser that will be in mc2 3.1 (currently 3.0) is really very nice (based on but changed a bit from the test files recently posted.)

You'll never find a parser that's super-easy to use, but this one is in C (no intermediate file), makes sense in C, and is debuggable in C so debugging both the code and the algorithms is much much easier than something like flex, lemon, or the gazillion other alternatives.

As kind of a challenge, we started the first few passes...

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.
