Another, less lightweight way is to use panels for different parts of
the chat windows. I put together a sample at

The simplest thing is to just use tabs. A line of text would be
"\tYour Message here" and an overflowing line would be "\tOverflowing
message". Yes, this will work for variable width fonts.
The `text%` class has a `set-tabs` method which allows setting the tab
stops in drawing units on the
That code is in the framework:

You might also consider having two text%s, one with the names and one with
the rest. They would scroll independently in that case, but you can hide
the scrollbars on one and
Hello,
I'm building a little chat application with Racket. Overall Racket's
GUI tools are quite comfortable, and I'm just using Rakcet's text editor
stuff to build the chat. But a fairly standard thing to do with chat
applications is to have text like:
(Beware, fixed width ascii art ahead)
Thanks Jens and Ryan for your answers! I’ll experiment.

I tried a few more versions of Racket, and this broke between 6.12 and
7.0, probably due to the new expander at that time. I'm surprised that
it works on Racket CS, though.

Thanks, your output helped narrow down the issue. It looks like the
problem is actually with the regular (non-Chez) variant.
When running with Racket v7.8 [cs] I see the same (expected) behavior as
you:

Welcome to Racket v7.8 [cs].

You can use the functions from macro-debugger/expand to do this (within
limits). Here's a very rough example program that reads one term from
stdin and shows its expansion with the given hiding policy (discarding
hygiene information---beware).
usage: racket expand.rkt < your-example-file.rkt
This works for me the way you describe:
```
[samth@huor:/tmp cs-snap] r -ie '(enter! "x.rkt")'
Welcome to Racket v7.8.0.7 [cs].
loading example
"x.rkt"> example
5
"x.rkt">
```
Perhaps there was a problem with 7.3 that you're running into? Can you
try with the 7.8 release?

Hi Éric,
This is a nice idea - I pondered the concept before, but today I got a
little further.
I am unsure whether the approach scales. You could look at nanopass too.
Anyways, here is a little experiment.

Hi,
I’d like to use the Racket macro expander to translate programs from a given
source language to a target language (both scheme-ish).
However, the expansion that `raco expand` does is too violent for my
purposes---I would need a way to specify macro hiding (as in the macro
stepper), in
