This is neat. I studied APL recently (through Ted Nelson's fantastic intro in Computer Lib), and ever since I've been intrigued by some of the neat ideas/conciseness that array languages offer. (I have too many side projects/side project ideas already, but would love to write a toy "modern" APL just for fun)

Check out J[1]. It's basically ASCII-APL though it lacks a toy modern implementation (in case you don't know, APL has one[2]).

What really annoyed me about array languages is that idiomatic code is nearly impossible to follow after a month, so I ended up aliasing many of the commands to more verbose alternatives and using longer traditional constructs like IF-THEN-ELSE.

That pretty much turned the language into weird-C-limited-to-binary-functions-with-an-array-stdlib, which kind of defeated the point.

Oh My God.. I tried to learn APL for about two days some years ago and all I gorked was just basic stuff. Then I found out J and recommended that to our APL loving Prof. who converted from his about $2000 expensive prorietary APL symbolic minfu to the free J alternative. I could write much more with J, but Julia still feels more natural.

I've not made any speed comparisons, but maybe you can give APL, J, Julia and SAC a bench? That would be neat! A simple hello world like example, for example using the same FFT algorithm, or "addition" loop would be enough.

Is it being maintained? Last release seems to be from February 2012.

It's still being actively worked on, due to a recent move to a different university a lot of the infrastructure (such as building new releases) is still offline, so the website hasn't updated in a while. Blame university IT departments.

Any public repository to track?

Arrays by row? Why?

vanderZwan2• 13 years ago

Because normal C is also row-major?

mbq3• 13 years ago

C only has vectors (1D arrays), the implementation of higher dimensions is up to programmer. I know there is this idea to use vectors of vectors to emulate matrices but it is not at all a part of the language (nor efficient).
