Thank you for the responses Vincent and Neil.
Neil, thanks for the information here-I will meditate on this and how to
utilize it.

Hello all,
Is there a package out there wherein a user can specify a syntax
transformer, and the macro expansions are used to replace invocations of
the syntax transformer in the source syntax, within the source file itself.
I guess I'm envisioning a sort of syntax aware find and replace.
Thanks,
Hey all,
One feature of typed racket that makes translation between untyped and
typed code somewhat less simple than adding or removing type signatures is
that certain forms require rewriting/alteration of the untyped form itself.
Others allow stand-alone declaration of the types prior to the for

I am attempting to do some further work on the frtime lang. Specifically,
I'm working out of a branch based on the pull request

I like the idea of having optional keyword arguments available in struct
field construction. In many cases, I find it more declarative upon reading
the code, though input takes longer. I just tend to recall names better
than constructor/argument order. It could help to understand the code if

Hello All,
I have been working on updating the frtime collection to use the Racket
lang rather than the mzscheme language. To this end, I forked on github and
created a new branch frtime-to-racket, which can be found at:
https://github.com/paddymahoney/racket.git
This branch contains 36 commits.

Following linking to this location, the language declaration resolved to
the frtime language within my github tree.

Hello All,
I forked the github Racket repo, and created a new branch in order to
update Frtime from the scheme or mzscheme #langs to Racket. This has been
progressing well, until I ran into a small issue that I think likely
affects most individuals working on Racket source for which collections

difficult it is to develop a good name for the generic function. However,
in this case, I'm on board. Thank you for your time.

Hello all, in a quest for greater concision, I'm looking for a way to

accepted practice for abstraction over definition introduction?|#

I'm attempting to ensure that shapes drawn onto a canvas don't overlap. In

Hello Matthew,
Mr. Spier reports that he is using windows Vista. If the message-box code
uses the message% class under the hood, then this is probably related to
the bug I noted: problem report 12714
Thank you!

Hello Mr. Spier,
I ran into this issue recently-are you using racket on Windows out of
curiosity? In short, I think you need to set auto-resize to #t explicitly
upon init'ing your message.
I submitted problem report 12714 to track this.
