Hi,
I'm in the middle of a GWT system implementation and wondering how it
would look a restful backend had been used. Racket seems like it could
have a nice place there.
Best wishes,

Thanks for all the good answers as usual.
BTW, rkt is very "practical" in the sense it makes me think about

We are working on it in a rather different context.

Creating images for each character you plan to display will probably
have two disadvantages: it will use more memory, and it will void the
work that the OS does to make letters fit together (ligatures and
sometimes kerning).
(Probably using picts is the right way to go.)

Thanks everyone for the suggestions.
Stephen, to answer your question, I want to be able to change the text
independently. The letter d, for example, I might want to show sometimes
in white, red, or green. I guess I could make a pic for each though.

Oh: what about turning the editor into a port and then using
regexp-matching on it? The position of the port will be a delta from
where you created the position of the editor. Eg:

Yes, sorry, I've meant string-snip%.
Okay, I'll iterate over snips then, because I need to match
whole character sets.
Thanks!

You might get away with just using the find-string method of text%,
but if not, then you do have to iterate snip by snip. The positions
inside string-snip%s are offsets from the position of the whole snip
for characters (is that what you're asking for when you say
text-snip%?).

Is there a fast way to iterate over items or words in a text% instance
starting from some position. For example, I'd like to go forward or
backward starting from a position until a character in a given

Using a string returned get-text doesn't seem to work in general beca
