It's always hard to find implementations of Oberon, so thanks for sharing!

If you (not pjmlp) are into compilers or Oberon I highly recommend Wirth's book, Compiler Construction, that walks through its implementation and his way of thinking about languages and implementations.

Edit: am I getting the language mixed up with the operating system he also designed?

View on HN

Wirth is the one full stack developer in existence :)

He created Oberon the language to implement Oberon the operation system and eventually designed a simple CPU to run the full stack.

Twice.

Well there is nand2tetris.org and probably others.

Wirth and his systems are a treasure of the CS universe.

I also rather like Wirth's Lola hardware language and RISC CPU. Great stuff.

Huh - hadn't come across this before but very nice HDL

There's also Chuck Moore, who created Forth, used it to create a bunch of operating systems the most notable of which is colorForth, then implemented chip design and simulation in colorForth and used it to design chips that run Forth (and his chips were produced and even used in at least one commercial product).

Nope, just like the Xerox PARC environments, for Niklaus Wirth the programming language and OS overlap, hence why it is kind of tricky to disassociate them.

By the way, Cedar was the inspiration for Oberon.

Although it is certainly possible to separate the two. For example, the Oxford Oberon Compiler for UNIX and Windows, which is just a compiler for the Oberon language (basically an object-oriented Pascal) rather than the OS/environment

Sure, that is why "Oakwood Guidelines for Oberon-2 Compiler Developers" eventually came to be,

My remark was more about how Niklaus Wirth saw the system he designed and his goals behind it.

You could make the wish to run an Oberon the perfect excuse to go into retro-computing:

There's also a book on OS, right?

Yes, but it is confusing because the system language of Oberon the OS is Oberon the language.
