to Format and friends (like Exception.CreateFmt) in your code. Or does
someone plan to write one, as an external tool (like a "lint") or

For example, the call

This thread, and my own tests, showed that you need to assign GUIDs to
interfaces to have reliable "is", even for CORBA interfaces.
I'm wondering, would it be possible to improve here things on the

I wanted to debug where my program uses the most memory. (There are no
memory leaks, but I want to optimize memory usage on some large inputs.
As the code is quite large, simply guessing which part is responsible
becomes quite hard :) In the past, I happily used valgrind's massif tool

The arguments however are listed in two separate arguments sections. It

Hi,
For people working with new OpenGL features: I just submitted a patch
to upgrade our GLX unit to GLX 1.4, add some new GLX extensions, and
add comfortable functions to check existence of a particular GLX
extension/version. This allows you to easily use modern GLX "FB
config" functions to initi

Hi,
Consider the attached source code. I have a base interface (IA) and a
descendant interface (IB). Class TB is declared as
TB = class(TInterfacedObject, IB) end;
Now I would expect that both
Supports(TB, IA)
Supports(TB, IB)
return true. After all, TB is forced to implement methods of
Just sharing, in case someone will find the below information useful,
or worthy to add to some wiki or docs anywhere:
I have here a daemon written in FPC that communicates with clients by
very nice TSimpleIPCServer class (in SimpleIPC unit). Of course it's
trivial to send a message to such server

SDL_opengl.h is just (one of the) cross-platform ways to include OpenGL
stuff in C programs. We don't need it in FP

Any hints or sample code. The sample included in FCL 2.4.1 loads MAD, A52,

All the talk about the Pascal parser in fcl-passrc got me interested
recently. I did some experiments, and I thought I mention here:
1. I added a simplest example how to use fcl-passrc to the wiki:

2. And reported a couple of bugs found in fpdoc (tested on P

This is the way it's supposed to work in delphi mode, as far as I
remember Delphi allows it (disclaimer: I don't have Delphi now to check,

I use Emacs most of the time to edit my Pascal (and all other :) ) code.
