doubletake...

    OpenLisp is a commercial product that is sold with
    binaries and sources (excepted memory management and
    evaluator). Full source licenses to make ports may be
    discussed.
judging by the linked charts, though... it's VERY fast.

i recently bought a book about learning Lisp, and i'm enjoying it very very much. it's weird though.


I just got my first developer position writing in Allegro Common Lisp, and I have to say I really enjoy the language, along with having an IDE that hooks into emacs [1][2]. For someone who is new to software development reading through the code is reasonable to do, and having a REPL at my disposal is quite nice.

which book if you don't mind to share?


Land of Lisp


I've been through that one a few times. I like the author's sense of humor and how he covers the history of lisp.

He is one of several people to help the lisp revival. However, after going through the book I realized that there wasn't anything here I couldn't do in arguably less lines of code in Python. SBCL would of course run much faster at least.

The prototypical niche languages (Lisp, Smalltalk, Forth, APL) are all amazing, but I've found that there are some good reasons they don't tend to take off. Some have been talked about on here ad nauseum though, so I will refrain from bringing it up.

Best of luck in your journey. There are a lot of really great lisp books out there!


> Best of luck...

thanks. this is my first programming book. about 13 years ago, a good friend turned me onto org-mode (and the emacs contagion, haha!). that kinda got me started on my developer journey. i recognized then that, for myself, i'd have to make a decision about what language to learn first, and it was a tossup between javascript (super popular at the time) and lisp.

i'm primarily a javsacript dev these days, with a few applications in production. as i start getting my feet wet with react & python, it's interesting to learn these two in parallel with lisp (lambdas, anybody?). i like what i sense as the honesty of lisp, it's so much less encumbered with methods, etc... and somehow more inscrutable.

i think i'll really like the data handling capabilities when i get my head wrapped around it, and i'm looking forward to some graph problems down the road. and then there's the passionate part of me that believes in foss/emacs & owning/contributing the entirety of my toolchain, so i'm doubly glad to be working with it in spac/emacs.

for the sibling comments, thanks for the recommendations. i'll probably need to get a couple more books before i really grok it.


As you or probably know, the best way is to really write a bunch of code. I've read a few lisp books and get the point of many topics and am even comfortable with a good bit of the language, but I don't fully grok it, because I don't have a good use case to try things out on.


You might be interested in Paradigms of Artificial Intelligence Programming by Peter Norvig. It showcases pretty amazing examples of conciseness and expressivity.


I haven't "read" it, but have flipped through it (definitely not the same thing of course) and looked at Norvig's lisp and Python code and can say he is waaay smarter than I am :)

It was a pleasure to read a bit of his work.


Practical Common Lisp, Common Lisp Recipes


I was 90 seconds into reading this article before I discovered that this is a commercial product, not open source. I am not criticizing it for being a commercial Lisp (I have happily used Franz in the past), but I feel like the naming could be better, e.g., ‘portable lisp’ instead of ‘open lisp.’


OpenLisp but not actually Open. Of course.


“Almost Lisp. Almost open. Fast. Almost.”


Open as in 1980's and 1990's "Open": X/Open, OpenLook, Open Software Foundation, OpenStep, Open Solaris, OpenGL, OpenMAX, ...


Open Genera


yea, that was unexpected and made me feel tricked into interrest in the software for a few minuttes


"OpenLisp is a KISS (Keep It Stupid Simple) full conforming implementation of..." You might want to rephrase that.


OpenLisp is a ‘fast’ interpreter of the ISLisp programming language.


Where are the sources code? I want to learn that:)


Lisp can be surprisingly productive. What kind of projects have been made with OpenLisp?

Anyone remember /r/place? https://www.reddit.com/r/place/comments/638zsn/high_res_fina...

I wrote a clone of it in a few hours using pg's Arc lisp: https://bit.ly/2UNwwpP

Hopefully the server doesn't melt. It's holding up pretty well so far.


Please note that OpenLisp is not only an interpreter. It has also a lisp->C compiler that allows to write standalone executables. Speed is then timed with an average of x20 improvement.

The source code is fully available to paid customers. They are allowed to embed a Lisp engine in their own applications.

OpenLisp is free to use for non-commercial application.

Open means Open to the world, not Open Source.

See more on Wikipedia.

How fast is the interpreter? Make your own benchs and see...

Last but not least, it is extreeeeemnly portable.

C.
