Oh, if you're going to do the simple syntax colorer, you can also do it
in JavaScript, in the browser. There are existing JS scripts for doing
this for various languages. I would prefer the result of using Scribble.

Scraping information off of Web pages was the first thing I ever did

Anybody have any idea where I should look for that?

I just found out that this doesn't work for Italian keyboard layouts
(http://en.wikipedia.org/wiki/Keyboard_layout#Italian). Sorry about the bad
info. :(

Alternatively, you could try the combination AltGr+4, followed by the next
character after the tilde (as if you were typing an accentuated vowel). This
works on my Spanish keyboard, where tildes are a nuisance too. I haven't tried
on an Italian layout, but I'm guessing it should work.

I'm evaluating whether to use Racket to data mine hundreds of websites pulling
out business information within an industry. I think Racket is up to it, but
I'm wondering if anyone else has had experiences positive or negative. I've
used other tools to do rudimentary digging, but this project i

PLaneT displays the source as HTML like this:
http://planet.racket-lang.org/package-source/soegaard/math.plt/1/4/number-theory.ss
Not to be too ludditian, but why not just pull it up in drracket in class?
If not, I guess you could put together a script that stuck
(racketblock ...) around everything or the module-enhanced variant,
which makes it into a scribble file and then run scribble --html on
that.

Given that Scribble does it, I imagine that there's a way to convert a
.rkt file into something that would look similar in a web browser. Is
there a (not-too-complicated) way to convert a file in WXME format
into something I could inline in an HTML document so that it would
look reasonable. Related
Hello,
I have made some modifications to the source code of racket and compiled it.
Now, I want to give the modified binary application to another person.
How do I make a binary distribution?

OK, I see.
I actually have some custodian thingies used in the child thread, but having
genetic-programming incubation going on overnight, the whole VM is usually
jammed. That's why I thought an extra, heavy-duty sandbox might "fix" the
situation.
Of course, I could just learn use custodians
Oh, you need to create a custodian, make it the current custodian when
creating the thread (with `parameterize' and `current-custodian'), and
then shut down with `custodian-shutdown-all' instead of `kill-thread'.

I tried first the original "system" procedure having
(current-subprocess-custodian-mode 'kill) mode applied. But that didn't have
any effect on kill-thread, and for subprocess-kill I should know the subprocess
id, I guess?
What am I missing here...?

To use `current-subprocess-custodian-mode'? The parameter applies to
`system', too.

Thanks Matthew,
now the problem moved to converting the simple "system" procedure to
not-so-simple "subprocess" procedure. My poor little non-programmer brain
overloaded after seeing the following :)

How about this? Make a file somewhere, put the code below in it and
then use edit|keybindings|add user-defined keybindings... and point to
the file.
You will probably have to change the "c:c;c:t" to something that isn't
used on your keyboard; that one is reasonable on a mac (where I'm

Hello,
in italian keyboards the character ~ is missing, and, on windows, the
usual way of entering it (Alt-126) does not work in DrRacket.
Could \tilde be added to the list of keyboard macros recognized by M-\ ?
Alternatively, is there a way to enter ~ in DrRacket that I have
missed? (other than
