tweetnacl VS janet

Because that product was an embedded system running on a very small SoC. It only had 1MB of flash and 192k of SRAM. It's theoretically possible to run CL on a system that small -- Coral Common Lisp ran on a Mac Plus with 1MB of RAM back in the 1980s -- but nothing off-the-shelf will do that today.

(I did, however, put a little Scheme interpreter on it as an easter egg :-)

I do have some CL code that supports the crypto project. The back-end for this:

https://stage.sc4.us/sc4/sc4tk.html

is written in CL (though all the actual encryption is done client-side in Javascript). I also have some prototype crypto code that I don't really use for anything, including this double-ratchet implementation:

https://github.com/rongarret/tweetnacl/blob/master/ratchet.l...

and some elliptic curve code:

Of course. There are many. Any binary format. Any ASN.1 format. DEF and LEF for hardware descriptions. The output of mysqldump.

Here's another example:

starting at line 82. (That's one that I designed.)

Seems like a perfect use-case for Janet. (https://janet-lang.org/) A fast minimal VM like Lua, but even more extensible than Lua by being a "Lisp" with macro and C extension capabilities. Not a true Lisp, it's very pragmatic and performance-oriented. But it keeps the good stuff.

It comes with a build tool `jpm` which installs dependencies globally by default, but you can have it be installed in your project folder as well.

I like Clojure, but I never had any good opportunities to use it other than for a few small hobby projects. It is unfortunate that it is so huge with tons of dependencies and no simpler native implementation. I started looking at various LISPs and Schemes to find something lighter to use instead and ended up settling for Janet that I think is Clojure-like enough to be comfortable to use, but in a small native binary with no dependencies and can be embedded in other native programs. I am sure for big, real, projects that Clojure makes more sense, but for my hobby projects and scripts I do not think I will install it again. I am still happy for the things I learned from learning Clojure. It was a real eye-opener for an old OO-programmer.

One might also check out Janet for quick scripting tasks.

Thanks!

I thought about another multiplatform, homoiconic, highly compact language: https://janet-lang.org/ (takes 803 kb on my machine).

It has no types though.

Racket is great, and if you like it you might find Rash interesting:

Janet and Gerbil Scheme are also worth a look:

Point here is that, for instance Janet language does not have cons / pair type but tuple (and so is lispoid, not lisp), but clearly this is sufficient for macros & hence seamless language construction: all you need is to be a lispoid although being a lisp gives another useful feature.
