i think it might be good to have front and center on the home page ATS vs. Rust. if anything is a “competitor” in the mind of Joe Programmer on the street, it would be Rust.

They don't have much in common really. ATS has linear types, and Rust has affine types. But ATS2 is a research language while Rust hardly even tracks developments in mainstream languages - though it has some nice aspects like a package repository and code formatter.

Those are all great things to put into a faq. :-)I think some of the folks looking at ATS would also be looking at Rust. Of course that doesn’t mean ATS has to talk about Rust but i feel like it would help ground ATS in the mind of a newcomer to the language, since Rust is fairly well heard of now.

Thanks a lot for your long and continual interest in ATS :)

I would like to wait a bit until I can get ATS3 to the point where I have

a clear idea as to what it is really like. ATS3 is unlikely to be like Rust.

I mean they try to address some similar issues in programming (for instance,

safety in low-level programming) but they use fundamentally different approaches.

ATS3 is meant to be the core of various meta-programming extensions.

Programming in ATS3 can be both ML-like and C-like and the default dynamic

semantics of ATS3 is roughly C plus C++-like templates. These are some of key

objectives I have kept in my mind for quite some time.

Cheers!

noob question:

Does that mean if you know C you'll be able to learn ATS3 (relatively) comfortably without knowing sml or some other ml variant?

[Vanessa McHale]

I have experience coming the other way (Haskell to ATS2), and I think it works well enough - I did pick up some C/low-level programming along the way, and the mailing list has expertise in both areas and can help you.

I suspect it will work the same going to other way, though I have a hunch ATS makes more sense to C programmers than ML programmers :)

Knowing C is very useful when learning ATS.

However, ATS tries to promote a programming style that is very different

from the standard style of writing code in C. In particular, my bet is on a

functional programming style that makes extensive use of templates so as

to greatly increase programming productivity.

So the bottom-line is that you can do C-style programming in ATS. If you want to

become more productive in terms of coding, you may need to practice template-based

functional programming in ATS.

thankyou very much for the replies, i'm very greatful.
