Re: [racket-dev] problem with require and frtime
I assume it wouldn't be too difficult, and that it's worth doing even if it doesn't solve this particular problem. Can someone grant me commit privileges?

(This seems like a further weakness of the `frtime' docs to specify the exports precisely.) You could avoid bound names like `=' as literals in the macro. Normally, it works best for a form-exporting macro to also export bindings for any literals in the form. Otherwise, this kind of confusion is common. Alternatively, you may want to match literals in your macro symbolically instead of by binding. You can't do that easily with `syntax-rules', but you can use `syntax-case*' and supply `(lambda (a b) (eq? (syntax-e a) (syntax-e b)))' as the literal-comparison function. If it were me and I decided to go in the direction of symbol equality, I'd use keywords instead --- `#:?' and `#:=' instead of `?' and `=' --- which makes clear that there's no question of binding.

This is a reduction of a different problem possibly caused by these issues here. So I tried to cut down my program to a reasonably sized test-case which is attached to this email. model.rkt contains (what's left of) the model macro, demo1.rkt contains a small model and a (require frtime). If you do racket demo1.rkt then you get the following error: model.rkt:30:17: make-entry: bad syntax in: (make-entry (= profit (for/hash ((y years)) (values y (- (hash-ref income y 0) (hash-ref expenses y 0) (years income expenses profit)) === context === standard-module-name-resolver but if you comment the (require frtime) then the error goes away. I have other code that tests this same simple-economy model with the non-cutdown version of the model macro and supporting code and everything seems to work fine. Any idea what's going on here?

Re: [racket-dev] FrTime propagation bug
Hi Marijn, The value-now/sync procedure waits for propagation to complete before reading a signal's value. Would something like the following suit your purposes? (define a (event-receiver)) (define b (event-receiver)) (define a+b (+ (hold a) (hold b))) (send-event a 3) (send-event b 5) (value-now/sync a+b) ; read a+b after propagation = 8 Or, even simpler: (define c (new-cell)) (define d (new-cell)) (define c+d (+ c d)) (set-cell! c 3) (set-cell! d 5) (value-now/sync c+d) Greg On Thu, Jan 12, 2012 at 12:49 AM, Marijn hk...@gentoo.org wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 11-01-12 21:26, Gregory Cooper wrote: Hi Marijn, FrTime propagates changes asynchronously.

Re: [racket-dev] FrTime propagation bug
Hi Marijn, FrTime propagates changes asynchronously. When send-event returns, there's no guarantee that the event has finished propagating through the system. And in general, (value-now b) is not well-defined, since asynchronous processing makes it difficult to define what now means; programs should only call this if they can tolerate stale values. (It so happens that evaluating (hold a) blocks your thread until the event finishes propagating, but that's an implementation detail. You can probably achieve the same effect through a call to sleep, for example.)
