Thanks, it works great! Nice to be doing Arc again. Also, looks like the bug where it repeats all kinds of things is not from scheme or arc but is rlwrap and ssh fighting. Because if I drop either one, it works again. Not yet finished documenting the bug.

Thanks for the link.

No problem. And for what it's worth, I don't use rlwrap, I use mzscheme's builtin readline: in ~/.arcshrc, I have the line

  ($ (dynamic-require '(lib "rep.ss" "readline") (zero? 1)))
, which provides readline functionality.

Thank you! That works wonderfully. It even saves readline history across (quit) and restart. The prompt shows up at different times now, but that seems cosmetic.

Glad to have been of assistance.

Oh, you're having the problem where you get

  arc> 
  (user-input (goes 'here))
instead of

  arc> (but:user-input (should-go 'here))
? I though I was the only one with that problem, and I hadn't realized that the readline was causing it. Unfortunately, I don't know enough about mzscheme to even know where to begin looking to fix it... I've seen it in other mzscheme things, though, so it's not just Arc.

Exactly! But let me try something. Okay, if I skip ssh that doesn't help at all. Readline moves the prompt like you described. Rlwrap does it, and so does the .arcshrc thing.

Funny thing is, debian's mzscheme + arc2.tar are fine, no problem at all. So it must be my mzscheme.

Well, it's mine too (Mac OS X, v372)—I wonder what the root cause is?
