Hi all.

I made a Squeak package for the 2011 Google AI challenge
(http://aichallenge.org), attached to this email. It works (but is
untested by fire) but I'm giving up work on it.

Basically, the AI challenge does things using shell and python
scripts. Bots are compiled and then interact with the AI challenge
through stdin and stdout. This much works for me.

However, I was hoping that I could get the contest organisers to
install Squeak in /usr/local/squeak, and then to run a user's
submission, the VM would fire up the image in /usr/local/...
somewhere, file in MyBot.st, run it and quit without saving anything
such that no access to the file system is necessary (which is
obviously a requirement for running code submitted by the general
public). This doesn't work; Squeak fails to file in code if it cannot
write to its .changes file.

I can't be bothered to work around this issue. If anybody wants to
grab my code and get the AI contest to support Smalltalk as a language
then be my guest.

Michael.

Hi.

I've written a starter package for Smalltalk, attacked to this post.
However, I'm giving up work on it.

This is based on Squeak Smalltalk 4.2 (the current version available
from http://www.squeak.org/). It works okay with the python tools
except for a trivial bug: food needs to be removed from the map. I
fixed this bug last night but then lost the changes somehow.

However, I tried setting up a "server" version of Squeak for inclusion
into the competition's VMs, and Squeak requires write access to a
"changes" file (which, for the competition, would be in
/usr/local/squeak/Contents/Resources/) in order to read in code,
compile it and run. To me, this is the last straw; I've dodged too
many issues trying to get this to work and I'm giving up.

If anybody else wants to fix it up and deploy it, be my guest.

Michael.
