Oz-CocoR-Delphi

Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.

Projet_fin_module_compilateurs

This project uses a very original approach to parse a subset of the Pascal language, and covers all the aspects necessary for generating an X86 assembly program. The project is a bit 'dated', but the way recursive descent parsing was implemented is worth a look.

Burn To The Brim

**Burn To The Brim** is a highly efficient archiving utility designed to solve the classic subset-sum (bin packing) optimization challenge. It intelligently selects and groups files and directories (documents, high-fidelity media, or raw back-ups) to optimally fill recordable Blu-Rays, USB drives or custom-capacity storage drives. By recursively scanning your designated folders, BTTB matches item sizes to your media capacity, finding a near-perfect selection in milliseconds and an absolute perfect packing configuration in just a few seconds. Burn to the Brim 4.0.0 introduces state-of-the-art machine learning semantic coherence logic to BTTB's classical packing algorithms.

PureGEM

PureGEM started out as a VCL/LCL style library written in PurePascal. After the system was working, I saw ways to increase the speed while reducing code size, so the design drifted somewhat. Since PurePascal is "Turbo Pascal 7.0 compatible" a number of VCL style features needed to be implemented differently. Namely TNotifyEvent's are replaced with owner recursive methods. RTTI features are implemented via set's. Initially I had planned to use more of the GEM API, but some of the features I wanted required replacing all window elements. This is a new library, so expect code to change. I will be working on this for the next 1-2 years. cheers Derek
