Link clearance: history of Pascal / Object Pascal / Delphi Language / FreePacal / …

Posted by jpluimers on 2014/02/25

This post lists a lot of links related to the history of Pascal / Object Pascal / Delphi Language / FreePascal / etc.

No mentioning of Pascal should start without Niklaus Wirth. At the time of writing he is still alive, hopefully he still is a the time of publication.

Link clearance.

Happy 30th birthday Mac!

Posted by jpluimers on 2014/01/24

Being away from a computer sometimes means you forget about events.

So before I forget: happy 30th birthday Mac!

For me, real programming started 31 years ago on an Apple II at high school, soon followed by a II+ and a //e. At first, I was programming in both Integer Basic and AppleSoft Basic, then with Apple Pascal (which was based on UCSD Pascal, but way too slow), and finally with Turbo Pascal 1.0 (after they installed a Microsoft Z-80 softcard in a few of the machines which allowed it to run CP/M).

Back then me, nor my parents could afford a computer like a Mac, but I was lucky enough to keep on people at the “close by” (30 minutes by bicycle) University to use one and program in hyper card and various Pascal dialects (and later Delphi).

Now I own a few Macs (most more portable than the //c) bought a //e and //c last summer and collecting some extension cards to make life easier.

Just look at the B&N magazine rack how popular the Apple stuff is today:

So again: happy 30th birthday Mac!

Without you, I wouldn’t be a software developer.

Adobe Photoshop 1.0 Source Code About 75% is in Pascal, get it from the Computer History Museum

Posted by jpluimers on 2013/02/15

Thanks Lennart Aasenden for sharing this on FaceBook: Mariuz’s Blog: Adobe Photoshop 1.0 Source Code About 75% is in Pascal.

This was back when I was already a professional Turbo Pascal for PC programmer, not yet a Mac programmer, but doing Pascal on VMS to assist a client in the scaleable font industry.

The 1990 version 1.0.1 of Photoshop code was written in Object Pascal, and based on MacApp.

Back then Apple’s Object Pascal was one of the few IDEs available to develop Macintosh software. Later on, you also had Turbo Pascal and THINK Pascal (which many Macintosh developers preferred, was later acquired by Symantec, and died). A big reason they liked it so much was the THINK integrated debugger, which was lightyears ahead of any Pascal product on any other platform.

Apple had great documentation, not only on their compilers and libraries, but also one that everyone should hav read: Apple Human Interface Guidelines: The Apple Desktop Interface: Inc. Apple Computer: 9780201177534: Amazon.com: Books.

The Adobe Photoshop 1.0 source code can be downloaded (for non-commercial use) from the Computer History Museum | @CHM : Adobe Photoshop Source Code page.

The source is a very interesting read, and a great comments on it by Grady Booch.

This is how everyone should think about their code.

PS: A nice introduction to Object Pascal for a Macintosh is at MacTech | The journal of Apple technology..
