Hi,

I just want to share with you a page where you can find many design patterns written in Delphi, if you may be  interested:

github.com/jimmckeeth/DelphiPatterns (http://github.com/jimmckeeth/DelphiPatterns)

regards,

Thanks for sharing. Isn't Jim McKeeth a delphi evangelist?
On a side note, design patterns are useful things, but people sometimes go overboard. I saw this before on job interviews, if you don't know what a singleton is they will shot you instantly without any further questions :). Therefore design patterns are abused and overused.

There are way more Pascal implementations of The Gang Of Four design patterns available.
And yes, he is currently a Delphi Evangelist.
He is a long time Delphi user, but I don't know if he was the above  already 5 years ago. (repository dates)

Delphi 7 already came with GoF in some editions

Yeah, the gang of four, I almost forgot. :) The design pattern bible for some programmers.

GoF was the mandatory reading in the design patterns course at faculty. IMHO it was hard to read...

Here you will find more examples, not only in Pascal. There's also general info about patterns, anti-patterns, etc

A design pattern is language agnostic. That can be hard to read if you keep the perspective of a language. It is science, philosophy. It is also essential, if you agree with the patterns or not.
