Hi,
Does anyone use Whalesong to script web pages?
As far as I understand the Racket design, Whalesong is enough to bootstrap full
Racket in a JS environment. It's a great opportunity. I would like very much to
have an interactive lisp development where I can develop both server side and

As far as I can tell, to get the highlighting to start in the position
after (so to highlight "[x (foo bar)]" when the insertion point is
before that quoted "]"), then you'd need to change the method I
pointed you to. I guess it would make sense to add an overridable
method that returns #f or a pos
With some difficulty, as far as I can make out :) The code overrides
on-paint and draws its own cursor. The insertion point does not appear to
be changed; the cursor display is just changed from a line between char@pos
and char@pos+1 to a box covering char@pos+1

The highlighting you're interested in changing is the (by default)
grey highlighting that moves around when you change the insertion
point (when you use the arrow keys, say), right?
If so, I think the code you're looking for is the match-parens private
method in framework/private/color. You can se
Let's say I have the following:
(let ([x (foo bar)] ... )
In the regular drracket editor, when I move the cursor between the ) and ]
it highlights (foo bar). In the vim emulator, the cursor has been replaced
by a block that highlights a character, rather than a line just before it.
So the same cu
I am not quite following what you want to do. Can you give an example

I'm trying to override the automatic backward-sexp highlighting in drracket
to highlight the sexp based on the ) after the cursor rather than before it
[https://github.com/takikawa/drracket-vim-tool/issues/13]. Is this
possible? I tried overriding flash-backward-sexp but it didn't seem to have

The package system knows the currently installed checksum. There's not
currently a simple function to look up the checksum for a given package
name, but you could use
(require pkg/lib)
(define (get-pkg-checksum pkg-name)
(define info
(for/or ([scope (in-list (get-all-pkg-scopes))])
Thanks a lot!
It sounds... amazingly simpler. It even supports branches!
Even readding support for auto-update sounds easy, to prevent human errors
by students. (It's certainly less work than I spent working around the
current system). I might even integrate this in the docs.

No, they don't provide glibc:

An easier way is:
* Create a Git repo (e.g., at GitHub) for your handin client. It's a
good idea to name the repo something specific to your class, as
opposed to just "handin".
For example, the one for my class is

Hi all,

Yes, that is correct.
