I've been struggling to get something working. Jon and Asumu leant me
a hand on #racket. I learned some ways to use patterns instead of
resorting to datum->syntax, which I can use in the future. But for
what I'm doing now (I need to sort arguments for a lambda) I don't see
any way around running th
Good job on being one of the very few HLL programmers to grasp the concept of
mixed-precision integer arithmetic! Assembly language programmers understand
this idea easily, but I almost never meet an HLL programmer who gets it.
I have a long history programming in Forth. Now I'm writing my own l
Slight correction. Comment line was too long and wrapped over.

I think one way to do it would be to use read-syntax to get the
expression, but then also put the file into a string. Walk the
expression and look for patterns that you want to change rounds to
squares and then mutate the string and write the file back out again.
Use the position field of the synta

That's a toughy. What you want is to be able to invert (read-syntax). It seems
to me that such a thing should be possible in many of the racket languages,
Good catch! Fixed.
Thanks!

My emacs mode at https://github.com/carl-eastlund/simple-sexp uses meta+[
to bracket-ify the following s-expression. Same for meta+( and meta+{,
although it doesn't always get reader macros right such as '( ... ) or #,(
... ). It tends to mis-detect them as non-parenthesized and leave them
alone.
(even better would be a way to racketify a whole file at once -- a dream?)

Hi,
I'm converting code written with only standard parentheses, introducing squared
ones where appropriate.
This is obviously not very fun (I'm converting all of OOPLAI), and it would be
great if there'd be a way to select an open paren and "convert" it so that the
matching closing paren is ch

The obvious way to handle strings is to turn the constants into
symbols at expansion time, and dispatch on (string->symbol ),
just like we handle chars by turning them into fixnums and using
fixnum dispatch. After that, it's a question of whether you want case
to work for lists, vectors, syntactic
Thank you, it's working :-)

I've pushed a repair for this bug to the git repo. Meanwhile, a
workaround is to wrap the `end-doc' call as
(with-handlers ([exn:fail:contract? void])
(send dc end-doc))

Hugh, greetings.
I think list members might experience a certain amount of surprise at your
conclusions...

Many thanks for the response, Matthew. When I realized (after posting) that
v5.3 changed the server's behavior, I just started running the server under the
5.2 installation I still had on my Mac, but I will pull down the new version
with your fixes sometime soon, so thanks a bunch!
