Classios – one more step in the evolution of Petros
In the past couple of years, I’ve been tinkering on & off with the new version of PetrOS. This is a total rewrite for a few reasons, but mainly that I was unhappy with the current code base in Petros. The original one was started at a time when Delphi wasn’t around – we’re talking the early 90’s.
What triggered the original development of Petros was the release of the Win32 specification and I felt that this was certainly a step forward in the DOS/Windows PC world. Win3.x was pretty rough as an OS and there was a need to go native instead of on top of DOS. I wanted to do it in pascal, but there wasn’t a 32 bit pascal compiler around at the time so I started writing my own. It was pretty much a spare time project over the years I ran Trumpet and I started with virtually nothing. Also, I’d always wanted to write my own pascal compiler and it didn’t seem too hard a job. Initially I stuck to plain pascal, but it was clear that I would need objects to be at least relevant to the modern world. All said & done, the compiler was a simple one spitting out assembler code, not a full language. Eventually in 2002 I did an amd64 version of the compiler but at that stage I felt it had reached the end of its useful life – it needed a rebuild too.
