Hi,
'regular' applies to me, I think. I use PLT Scheme a rather simple way and nevertheless came accross the same problem. I frequently
update to the most recent PLT Scheme Full from http://pre.plt-scheme.org/installers/ (option 1). I run my modules by means of
DrScheme or by means of executables made by DrScheme's menu Scheme/Create Executable. It would be nice to have an option to
automatically recompile from source in case zo files do not correspond to the correct version, just like they are automatically
recompiled after the source has been modified.

Yes, it could. That's the second option I suggested below. I was more
conservative, tho, and suggested that it only be turned on with a
flag. But perhaps it should be disabled with a flag instead. I think
we probably want it off by default for the mzscheme binary, tho, since
mzscheme will inprinciple be running in all kinds of places that
shouldn't do things like write to the fileysystem.
That's why I said 'use source'.
I like this best. (And yes, I am an svn user and by golly I can get around this, but I wouldn't be surprised if this could happen
to 'regular' people.)

Perhaps I am naive, but could mzscheme just automatically compile files when
it finds that compiled/ is out of date? or use the source file instead?

I see a few possibilities. I think that this is a problem specific to
people who work regularly with SVN, so we can expect such people to
have extra sophistication:
- (IMO, the second best option and one that is available now):
instead of saying "mzscheme file.ss", say "mzc file.ss && mzscheme
file.ss".
- (IMO the best option): mzscheme should get a commandline option
that amounts to doing the above for you automatically. So intead of
"mzscheme file.ss" yo'd say "mzscheme --compile-zo file.ss" or
something.
- disable automatic compilation in drscheme.
- (the saddest option): by default, have automatic compilation in
drscheme turned off by default

Now that drscheme compiles things behind my back, I am encountering a new
problem al the time.
1. I have a fair number of scripts. Usually I run them with mzscheme ...
or
mred ... or it may even have the right Unix incantations in the file.
2. I also tend to use auxiliary files and my own small private collects
of
auxiliaries.
3. On some occasion (I thought it was rare but it happens often enough
since
the switch for me to notice) I open these scripts in drs and run them.
Now
the aux files are compiled.
4. I regularly update my plt installation from source (say 3-4 times per
week; usually every day).
5. Oops, I can no longer run the scripts because the compiled files are
version n-1.
I'll just stick to describing the problem here, just in case there's an
obvious solution. -- Matthias
