Not sure I understand your question, because to me `file-list' does drop
comments.
You should be able to see its definition simply by typing `file-list' in a
DrRacket definition window, right-clicking on it and selecting Go to
definition.
It's in collects/racket/file/file.rkt, around line 622.
for the following code :
(define e (make-evaluator 'racket/base))
(let-values ([(i o) (tcp-accept (tcp-listen ))])
(parameterize ([current-input-port i]
[current-output-port o]
[current-error-port o]
[current-eval e])
for the following code :
(define e (make-evaluator 'racket/base))
(let-values ([(i o) (tcp-accept (tcp-listen ))])
(parameterize ([current-input-port i]
[current-output-port o]
[current-error-port o]
[current-eval e])
Side comment: you are missing the #lang line and requires, so
technically the code you have above is ambiguous. Don't omit those
next time.
tcp-connect from another machine opens up a port, like the other
port-opening functions for files. What issue are you encountering
with tcp-connect? I
Hi there,
Since current-seconds isn't a paramter, is there a way to parameterize it
similar to the examples of overridding the current-error-port, etc?
I can (make-parameter current-seconds) but naturally this doesn't affect
any calls to (current-seconds) that happen in that scope.
Thanks.

Hmmm. Thinking... can you parameterize the sha1-hash constructor
instead, since that's probably under your control?

Is there anything obviously wrong with this approach ?

Thanks for tracking this down!
Just to make sure, does `--enable-libffi' work for you? It should be
the default, actually.
When I tried before, `configure' failed to use the installed libffi
because `-pthread' is needed for linking, and it wasn't included in the
result for `pkg-config libffi
I edited the source for the optimization coach and to comment out the
define/augment on-tab-change and my augment is now working !
I will file a bug for this.

Which version of Racket are you using?
The current (git) version of Optimization Coach[1] calls `inner' as it
should. I fixed that bug some time ago.
Sorry for the trouble.

I'm using v5.3.3 on OSX.
I found that supplying #f to get/extend, as in -
(drracket:get/extend:extend-unit-frame frame-mixin #f)
works around the issue (which is odd since #f is the default according to
the docs).
Thanks for the response and fix.

Let me play around, as I'm not super familiar with parameterization in
racket. If I can parameterize arbitrary procedures like the sha1
constructor, then shouldn't I also be able to parameterize current-seconds?
I think there's a gap in my understanding :).

I mean, if you have a function f that's currently calling into the
sha1 hash function, passing it the current time and secret key, can
you adjust f so that it consults a parameterization that you own?

Ya, could do something like that. Thanks.

Hello Juan Francisco,
Upgrading libffi to v3.0.9p2 (via ports) and using:
CFLAGS=-pthread LDFLAGS=-pthreads ../configure
--prefix=/usr/local --enable-ffi --disable-places
--disable-futures --disable-docs did the trick
for me. Thank you for your help!

Thanks; I've fixed the docs bug.
FWIW, your code works as expected in the current git head.
And I've been thinking about your earlier message (subject Developing
DrRacket Extensions in the same process). I haven't had time to do
anything with it yet, but I hope to at least make the situation a
