Agreed w/ John. I tried reading the Scribble files in the examples directory
but my eyes started to bug out a bit.

Hey everyone, I"m new to the racket language and was wondering if anyone can
help me explain keyboard movement for an image I'm using for a game I'm trying
to make. And yes I know there's a documentation page for it, but I'm having
trouble figuring out the correct syntax to go about it.

Ok, for reference, in ‘share/pkgs/drracket/drracket/private/rep.rkt’ it extends:
(class->interface text%)
text:ports<%>
editor:file<%>
racket:text<%>
color:text<%>
Of the methods it adds to that, the ones not documented under
‘drracket:rep:text%’ are:
copy-next-previous-expr
copy-
Indeed, these docs were written a long time ago.
also, (listof any/c) is the same thing as list? in the contract system.

I think the intention of the docs is that `drracket:rep:text<%>` is the
interface for all of the methods listed under the `drracket:rep:text%`
class. It looks like at the very least it extends the `racket:text<%>`
interface, this is likely just an oversight in the documentation.

The docs for ‘drracket:rep:text<%>’ just say it's an interface, without listing
any interfaces it extends, nor methods it contains. Is there a public API it's
meant to have and have documented?

Is it legacy, or is there a current reason/heuristic to choose it over ‘any/c’ ?

“Quick: An Introduction to Racket with Pictures”, and HtDP2e “Prologue: How to

I thought raco pkg update was unable to turn a catalog-package into a
locally-installed package, but I might have tried it at the time
within the directory itself, instead of cd-ing one level up like you
said.
Thanks for the tip!

It appears, e.g., in:
(send a-drracket:rep:text display-results results) → void?
results : (list-of TST)
A search of all racket files shows it used at times for values to be displayed,
but I can't find a definition of the term, nor just what it's [presumably] an
acronym or abbreviation for.
I see the same behavior as you with the v6.8 release.
The problem is related to cross-compilation and path conventions. A
cross-compiled build (such as the Windows distribution) starts with an
"info-cache.rktd" that has paths in Unix format instead of Windows
format, and `raco setup` (as run by `r
As you say, it works with "#lang algol60", but I can't find "Algol60" in the
language selection dialog on DrRacket 6.9.0.1, only R5RS, "Pretty big Scheme"
and "ProfessorJ" (which I installed manually).
Which version are you using? Which version were you using when it used to
work?This may help
I hope that there's a better way, however what I ended up doing was this:
1) Install a "Minimal Racket" from
http://download.racket-lang.org/releases/6.8/ (scroll down a bit to see these
versions).
2) cd path/to/my-clone-of-plot/; raco pkg install
3) raco pkg install main-distribution
