BAScript

BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Delphi, Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. The virtual machine defines its own language, called the BAScript language. It is a low-level language, somewhat similar to the Assembler language, which is not intended to be easy to program but easy to execute. So it is recommendable to use other higher level languages and translate them into BAScript language. Package includes two compilers that translates from a higher-level language to the BAScript language. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript.

Libxml2 for pascal

IMPORTANT NOTE: This project has moved to Github: https://github.com/pkozelka/libxml2-pas Pascal units accessing the popular XML API from Daniel Veillard ( http://www.xmlsoft.org ). This should be usable at least from Kylix and Delphi, but hopefully also from other Pascal compilers (like freepascal).

Scimark for Delphi Lazarus Free Pascal

Benchmark for scientific and numerical computing. http://math.nist.gov/scimark Some years ago, someone converted the sources to delphi. The result of that convertion can be found here: https://code.google.com/p/scimark-delphi/ I found some issues and tried to contact the author. Without success. That's why I decided to start a new repository here. Patches are welcome!
