I don't think that's currently possible.
You might try adding it as an option in the lw->pict function (or
something it calls). Beware, tho, that an ellipsis can have anything
at all inside it, so some care will have to be taken to get it to look
reasonable (I think it doesn't have to look great i

As part of the rsound package, I find myself reinventing data flow languages;
or, at least, the parts that I need. I've come to a design question that I
don't know how to answer, and I'm hoping that those with more experience can
make suggestions.
First: I'm re-inventing dataflow languages beca
Hi all,
Is there any easy way to globally re-write the ellipsis pattern in Redex
to some other representation of a sequence? (for typesetting)
For example, re-writing

I couldn't think of a way to do this with lw-rewriters since those

In the Racket context this should be almost trivial, since you don't
need markdown -- just have text with @scribble things that have the
json stuff as-is instead of parsing
I was just using DrRacket, and without thinking, used cmd-period to cancel a

Hi all,
I'm having trouble loading a 16x16 monochrome image such that it can be
used as a cursor%.
The documentation states that using load-file with a kind of 'bmp always
loads as colour, but it would be nice to have a new kind (perhaps
'monochrome-bmp) that loads monochrome images to monochrome
Another consideration is that the db library doesn't support Microsoft
SQL Server directly. It may work fine via ODBC (I don't know
first-hand because I haven't used SQL Service since `db' was added to
Racket).
In a previous life I did use FreeTDS with Racket on Linux to talk to a
SQL Server. A du

I won't call it crazy.
Can I call it overengineered?
I would write the following in T-SQL to achieve what you want:

reconfigure

I am the one full-time technology person at a small college prep school. My
background before taking this job five years ago was 22 years of commercial
software development and a bachelor computer science degree. I have been
interested in Lisp since I first heard about it in college, but have ne
What do you mean by polymorphic?
parametric polymorphism: this is a type-level concept with no true material
counterpart on the dynamic level. Since Racket is untyped, you can't ask for
this. Naturally Typed Racket comes with first-class polymorphic functions.
ad hoc polymorphism, aka generi
Hi,
I realized recently that one thing I miss in Racket are polymorphic core
functions (car, cdr, map, etc.). So I was wondering what it would take to
make them polymorphic. What is the best way to implement a polymorphic
function in Racket? Any ideas, suggestions and critics are mighty welcome.
