I am just learning racket using the real of Racket book.
However I am have problems wil file formats.
My .rkt file has become gracket format but I have no images or any non
ascii/unicode text in it. This messes up version control and use of other
editors.
How can I force DrRacket not to corrupt

I think the best path forward probably involves changing DrRacket so
that, on a case-by-case basis, people can opt-in to loading specific
external libraries automatically. I've not yet tried to implement
that, but if someone wants to, the right starting place is the code

Hi Mark,
How are you starting your program?
Are you launching Racket from a command line or launching by e.g.
double-clicking an icon in the Windows window manager?
What version of Windows?

Hello George,
Let me describe my use case first so that it's easier to clarify why
bigfloat or double-double don't work for me. The program I've been working

Exactly. We don't change anything about Racket 1 in a way that makes
any adaption needed. That's why putting a new "#lang" at the top of
new programs is such a big deal, because we can have a new level to

Showing that you defend a copyright is not just for any legal status of
it, but so that others take it seriously (e.g., are less likely to see

We already have such a mechanism.
The Racket 1 code is prepended with
#lang racket

and everything is interoperable.
That it will be interoperable is something that must be committed to,
unambiguously -- it is not something #lang implementors get for free.

With no changes. That's certainly what the Racket core developers mean by

There are a few things not clear to me about scribble.
Scribble programs start with a line

This invokes a different language from the regular Racket, with its own

Changing the canonical syntax seems like a bigger jump than from PLT Scheme
to Racket.
Perhaps a name change would help.
I looked up English language anagrams of racket and found two: retack and
tacker.
*retack** [Nautical] To tack or alter course by sailing into the wind for a

"New Coke" was horrible ... tasted like the bastard child of Pepsi and
Dr. Pepper.
And no matter what they claim, "Classic Coke" never was (and still
isn't) the same as the original. Classic Coke hit shelves a mere 3
months
That's actually really cool that you had both available to taste. My analogy
doesn't totally fit, but the preliminary discussions of Racket2 looked enough
like the preliminary discussions for New Coke to remind me of them--and to make

It isn't. It's been mentioned several times that "Racket2" is
