Free Pascal Random Bits

Release 0.4 is the new stable

2012-01-07T17:25:00.001+01:00

The previously released version 0.4 was found to be working w/o known bugs with the latest stable FPC 2.6.0 (svn revison 19485). Now virtually rereleasing the RC1 as the "offical" stable.

heLib release 0.4

2011-12-11T22:35:00.001+01:00

This is a RC1 of heLib for FPC 2.6.0 (soon to be released Free Pascal version). Compatible/tested with tags/release_2_6_0, rev 19814. Download source tarball here. Expect a release version (say, version 0.5) soon after FPC 2.6.0 gets out if this RC1 is not going to work with the final FPC 2.6.0 and/or issues will be found and fixed in heLib 0.4. Online documentation. Status: $ ./helib_test -a -p

Anybody out there?

The helib/heContnrs latest release (0.3.1) is once again dead for the time being due to a compiler internal error with the latest (as of today) trunk FPC. This is no rant about the trunk version changing. That's actually a good thing - the dev team is continuously improving it. The problem is to play catch up with the trunk. It was my decision to base heContnrs on the trunk version. It was the

heLib release 0.3.1

2010-12-22T22:41:00.004+01:00

The recent changes in the trunk FPC generics made all previous heLib releases broken. Release 0.3.1 addresses this situation. Otherwise no new classes/features were added. Direct source tarball download link.

Generic B+Trees (heLib release 0.3)

2010-09-10T15:11:00.001+02:00

FPRB/heLib/heContnrs.pas has got a new container type - generic BTrees.

heLib release 0.2

2010-09-05T13:41:00.000+02:00

FPRB/heLib/heContnrs.pas has got a new container type - generic lists.

heLib release 0.1

2010-09-01T22:54:00.000+02:00

FPRB/heLib 0.1 has been released today: Generic vector containers with generic enumerators. Online documentation. Test suite. Permissive BSD-style license. Requires trunk FPC (2.5.1). Resources: Source tarball downloadable directly from the project home page. Subversion access Ideas, code reviews, testing, bug reports, code contributions etc. are welcome.

Containers with multiple enumerators

2010-08-22T17:51:00.001+02:00

Paul Ishenin is, AFAIK, the author of the FPC enumerators support implementation. In his article on the FPC Wiki "FOR-IN LOOP", section "Proposed extensions/Select which enumerator to use", one can read (I hope it's allowed/legal/fair use to reproduce here the part of interest): It is impossible to choose among different possible enumerators. For example you can traverse a tree using different

Introducing heLib

2010-08-17T15:47:00.000+02:00

Started the fprb project at Google's Code. Hoping to, as time and circumstances permits, collect there some previous random bits as wishfully the future ones. When something worth mentioning becomes available, it will be presumably announced on this blog. ATM one can find there a work in progress state of a generic [object] vector with generic enumerators, roughly/conceptually corresponding to

WebKit/Gtk Experimenting

Don't expect the program to run and/or compile on Windows without modifications. program GtkLauncher; {$mode objfpc}{$H+} { This is a FPC port/modification of the original source from: http://trac.webkit.org/browser/trunk/WebKitTools/GtkLauncher/main.c - Tested
