I've pushed a script for globbing to the package server. It exports two
functions, `glob` and `in-glob`. I hope that some day functions like these
can be in racket/file, but until then, enjoy.
(glob "./files/*.rkt")
Returns a list of all files ending with the .rkt extension in the directory

Well the point of using the configure-runtime was that it would run when it was
the “main" program so that exact-decimals would work in the repl, but if this
file was required as a library, it wouldn’t set the parameter for the other
program.
But should the tests be thought of as the “main” pro
I believe the intention of configure-runtime is that it runs only when
your file is run as the main program and not when your program is run
as a library (via require). So I don't think you can use that facility
to implement the exact-decimal language.

For my exact-decimal meta-language, I had some tests that depend on the
read-decimal-as-inexact parameter being set to #f by configure-runtime.
It seems like raco test isn’t running that before running the tests. Is that
intentional?
(by the way the tests are not within a test submodule)

The check-equal? function and friends don't do anything special to delimit
control, so failing a check will abort the whole program if it isn't contained
within a test case. You can use the test-case or test-begin forms to limit the

I’m writing a test suite, and I’d like a way to abort a test without aborting a
test suite. It looks to me like “fail-check” is supposed to do this. Here’s
the code I wrote:
#lang racket
(require rackunit)
(define (f x)
(fail-check "foo")
(/ 1 0))
(check-equal? (f 3) 4)
(check-equal? 9 1

Matthias, at least in this new address the PDF is a broken link. It
currently points to
http://www.ccs.neu.edu/home/matthias/manifesto/manifesto.pdf
which yields a "file not found" answer upon request.
