Here's a little expression evaluator for Guile 1.9 using the new
bytecode compiler. It does arithmetic, exponentiation, modulos, and
equality tests. See the tests at the bottom for example expressions.
This is probably the most dense Scheme program I've written and I
would really appreciate a criti
It's getting pretty annoying that char-set-contains? rejects #.
Is there a way around this without wrapping it myself? Is that
behavior intended? Because to me, it seems like it'd be more
reasonable to return #f when passed #.
R5RS specifies that character predicates should return #f, and Guile's
character predicates are implemented in terms of char-set-contains?
R6RS says the same for char-set-contains?
The reason it bothers me is because it makes it cumbersome to deal
with input from a port. Case in point:
> $ grep "
>>(define y '(1 2 3 4))
>>(define dt 1)
>>(define foo
> (lambda (t) (do ((i 0 (+ i 1))) ((> i 3)) (if (and (>= t 0) (and (>= t
> (* i dt)) (< t (* (+ i 1) dt (list-ref y i) #f
DO does not return its body. It can be a little confusing.

Is that the issue I bumped into with (rnrs control)?

Guile was not compiled until recently. Most distributions only have up

Guile is gradually coming to support multiple languages, including a
Lua 5.1 implementation which I am working on right now. So they are
not necessarily mutually exclusive.

I would use records instead of lists. I think you can also make the
input much simpler, for instance it might look like this:
(define-table projects
(integer id primary-key)
(string name non-null #:length 32))
