Sam and Vincent have been working on lowering the load time for Typed Racket,
and have done a great job over the past year. As I understand it, there is
however a massive overhead from building the initial environment, because it
cannot be serialized at the time that Typed Racket itself is built
When I run the simplest possible racket program in DrRacket definitions window

the result 1 and the prompt appear instantaneously in the interactions window,
but when I change this to typed racket

it takces two seconds before the result 1 and the prompt are d

I apologize if this is a known "feature" or a known "bug" -- I do scan
the release notes briefly when new versions come out, but don't remember
anything

A colleague stumped me and I confirmed the behavior...
* range is a provided procedure, but suppose we redefine it ourselves, in
curried form:
(define (range lo)
(lambda (hi) (if (> lo hi) null (cons lo ((range (+ 1 lo)) hi)
or

Sam and I have been developing a prototype language using redex and
#lang for about a year now, and that's been a really great experience (I
don't believe we could have done this research and gotten it right
without this tool support).
But on my way to OOPSLA I re-implemented some of the core
Updated to the latest Racket master in git and some of my key bindings are
failing.
Typical example.
(keybinding "c:\\" (λ (editor evt) (send editor insert "λ")))
The key binding is invoked, however, I'm seeing the following in a pop-up.
Error running keybinding.

(regexp-match #rx"c\"d" "abc\"def")
and
(regexp-match #rx"c\\\"d" "abc\"def")
seems to work.

You have to escape the quote too...
Hey,
I want to build my new web-application with the racket-webserver, so I have

Now i want to improve the simple blog from the tutorial to learn more
web-server tecniques which leads to some questions:

Hi the list,
new problem with parsing a string with double quote inside by a
regexp-match function.
When I insert \\" in the pattern, the double quote is interpreted as the
end of the pattern.
Does anyone know how to avoid this?
Thanks in advance.

How are you checking "in the system"?
putenv does not make a global change to your system settings, instead
it changes the environment locally. For example, on Unix (it would
work the same on Windows, but I don't know a lot about the Windows
shell),
[outer] $ FOO=1
[outer] $ echo $FOO

Hello friends,
I try to change my env variables in windows 7. getenv works fine, but when I
change a specific env variable it returns #t but in the system there are no
changes...
