Shriram's proposal and a private conversation with Mike suggested
the following feature requests for the drracket teaching
languages:
1. Could drracket limit the width of programs in the teaching
language world to 80 columns?
This one seems doable (I'd probably make the text turn red when it
passes the 80th column or somethign instead of rejecting
keystrokes).
Ha! Back in Cornell I had a "DrSwindle" thing, which was a hack of
DrScheme that was needed since it was in the pre-module-days and
swindle was changing too much fro DrScheme to work. One feature that
I was sneaking in in addition to making it work with Swindle was an
80-character line limit, which I've always wanted.
So, it would be nice if there was a general option to turn this on,
not only for the student languages.
2. Could drracket reindent all every time a programmer hits
{return | run | submission server request }?
I reindent-all/check-syntax subconsciously, so my hot keys for
reindent would last longer. I'd like reindenting and reformatting to
occur whenever 80 lines is approached, within the current definition
under edit. In effect, do automatically what Dr already does nicely:
highlight from "(define..." to the insertation point, and hit tab. I
program by shooting for 72, and accepting 80 if necessary.

I'd be worried about this that some edits one does (maybe opening a
string?) would cause strange things to happen to the editor based on
intermediate states of the program. [...]
(And from a non-teaching-language perspective, there are cases where
you want to change the indentation for some reason. (*I* do that
too.))
