Hello,
I have been trawling through the packages at:
http://pkg.racket-lang.org
And have found that very few of the packages have any licensing information
and are effectively proprietary software, despite what their authors may
have
intended. I can therefore study them, but not use them
Licensing info should be part of the metadata for a package.
McFly actually has the licensing info for a package be in the package's
info.rkt. McFly includes that info in standard places in the
package's formatted documentation.

Hi all:
I have encountered a situation in which I don't know how to specify the
contract for a method that:
1. Has a final optional argument
2. The value of the optional argument makes the method change the return
type of the method.
It is similar to this:
(define/public (get-whatever
I've added license information to all of the packages in the main
distribution.
Thanks!

Hi,
I'm starting to fiddle with DrRacket plugin ideas (again), and I was
wondering if any tool developers can share their processes for developing
tools,
What I used to do was dump my tool in a collects directory and run 'raco -L
toolname', followed by restarting-the-Doctor. If it failed I would

They would be very welcome. Github is especially convenient
If I knew the answer I'd tell you, and hopefully someone else will.
Meanwhile, another way you could look at this: If it becomes too
difficult to write a contract (or documentation) for a function, it
might be good to revise the function.
For example, a function that takes an optional argument

When writing code that require DrRacket to restart I usually open two
DrRackets. In one instance of DrRacket I write the code - this is usually
in an old version. In the other I test the code. This way I don't need to
reopen the source file after each restart.
Another tip: To make DrRacket
Is there a way to catch the errors (more like warnings actually) thrown by
the db?
`with-handlers' does not do the trick since racket does not fail on them,
and a little search on the mailing list did not return relevant info.
The purpose is to use check-exn and check-not-exn on a generated db.

Best regards,

The example you give for C, you're right, it is not appropriate for C because
C has a (lax) static type system.
Let's call it what it is: unsound. Let's also agree that C's type system is so

That was quick, I hope it wasn't too much of an ordeal to go through them.

Also, this might help with the dynamic-require approach:

You can simulate and -im with -i by adding a mandatory (first) argument
with contract any/c.
