Search - "lisp interpreter"
-
So, this is probably somewhat esoteric but...
While studying at university I had a "programming paradigms" module, dunno why they called it that, it was more like "introduction to functional programming".
So, it's kinda mind bending, we'd only really started to get our heads around classical object oriented programming and they throw functional programming at us.
It's worse than that though, for do they use an established language, like lisp/scheme, functional Python, or even given Haskell?
No, of course they didn't. They taught us Oz.
You probably won't have heard of it, but this language is burned into the back of my brain, along with a vague understanding of the n-queens problem we had to solve graphically (using qTk, which I dunno if someone took qt and tk and blended them, I stopped asking questions after a while).
To top it off did this language (at the time) have a stand alone interpreter? Did it buggery! It was coupled to the Mozart programming system, which is just Emacs (which has a bloody lisp built into it,so close, yet so far 😭).
It gets worse, though, oh does it get worse, for pause dear reader and consider, have you ever heard of Mozart/oz before, I'd put money on most of you had not heard of it until today.
For, you see, I believe at the time of writing, one, yes, ONE text book exists on this language. When I was doing my assignment there was merely some published conference notes and language design documents.
That's not all, I was not the only one experiencing difficulties with this language, someone in the class ended up pouring through the mailing lists and found the very tutor teaching the class struggling at first to understand the language.
I had to repeat that year. The functional programming class was one semester.
When I retook that year, it was a whole year long. However, halfway through the year, original tutor was fired and a new tutor was hired to teach the language.
He was, understandably, just as confused as we were.
There was a Starbucks and a pub equidistant from the lecture hall, though in opposite directions. From lecture to lecture we had no idea which one we'd end up in.
I have reason to believe Mozart/Oz it some sort of otherworldly abomination designed to give students the occasional nightmare flashback, long after they've left.
My room had post it notes, sheets of paper, print outs, diagrams, doodles and pens, just stuck to the wall, I looked like a raving lunatic three hours away from being institutionalised. There was string connecting one diagram to the next and images of a chess queen all over. As I attempted to solve the n-queens problem.
Madmans knowledge, I call it. I can never unlearn all that, in fact it seeps into much of the code I write. Such information was not meant for the minds of a simple country bumpkin such as myself...
Mozart/Oz... I wouldn't be the programmer I am today without it, and that's frankly terrifying...10 -
Hey everyone!
I've created an interpreter that I am very proud of :)
It's based off the variation of Scheme(I think, maybe just Lisp) called Lel.
So my language is like a variation of a variation of Lisp... Written in an Interpreter(Python).
I've got a wiki, and source code on GitHub:

Thanks for any feedback. And help appreciated!11 -
Last night, while under the full belief that I could write a very simple lisp interpreter, I was awake until stupid o'clock and to my credit I got the tokenizer working and produces an output of parsed code. It's really basic but I was pleased to have gotten anything correctly parsed at that time.
But I'm also sitting outside my apartment waiting for a locksmith because lack of sleep left me unprepared to function correctly today and I'm now locked out...
Well done me! -
!rant Eeeeeeeeee!!!! The interpreter can now handle floats and integers! And accept the power operator! And modulo! (Sorry, absurdly excited)2
