A lex&yacc-like pair of parser tools is included in Racket, and works
OK. http://doc.racket-lang.org/parser-tools/

Hi All,
I would like to develop a simple compiler for a declarative language in
Racket (as a personal project), and am at a bit of a loss as to how to
proceed with respect to how to process text in Racket. What is the standard
means of reading a sequence of string (or characters) from a file?
Als
It is extremely unlikely that out of date .zo files could cause this, altho
it is, in theory, possible.

Perhaps you're thinking of the Racket Developers mail-list:

Thanks Robby, a nice teaching gift.
I think the problem has "gone away". Realizing my ad-hoc test was run from
the file in which url triggers the error, I set about to embed the test in
the file / dr racket window that generates url.
I ran a test function, starting very simple and step by step ge
Since there's little background here, I thought I'd just add that this
feature you're coming across is one of the critical things that underpins
Racket and differentiates it from languages like python and ruby. That is,
what you're seeing is that Racket has a way to make unforgeable values.

Here are two ideas.
1) You simply have an old use of the original net/url. When # is
printed, it uses the symbolic name and you can't really figure out
what the underlying code came from. I would do a grep to make sure
this is not the case.
2) You are using namespaces somewhere and actually have

Excuse my poor experience with contracts, this is probably an easy one.
I'm using a copy of net/url and have a strange problem. The copied library
is working fine in general, but this problem cropped up today:
struct:exn:fail:contract:blame url-port: contract violation

Dear Racket Users,
I have been writing a document in Scribble, without output to PDF. The table of

Is there a list-serve dedicated to Racket or Scheme principles and ideas...
or future development.
I remember reading about Racket designers taking a decision to split the
software,
one to serve the minimalists,
one to serve the rest.
Is there a list-serve, Racket or Scheme, that has such a focus?
Here's the reproducer:
(require pkg)
(install "github://github.com/iu-c211/c211-libs/master")
The error comes in the documentation building phase, for example:
link: bad variable linkage;
reference to a variable that has the wrong procedure or structure-type
shape
reference phase level: 0

Hi Sam,
I was replacing net/url, but with a copy of the system library which I was
modifying in a way that would not alter the existing public interface. I
was relying on some external packages like racket-couchdb that I'd rather
keep working as-is in terms of the net/url interface. At least at th

work with racketeering.
