Excellent evening

[ja...@ioctl.org]

That was a very interesting evening - trying to find a good introduction
to functional programming is a real challenge, I think, but I hope we made
some progress.

Far be it from me to invoke the oracle, but this:

http://stackoverflow.com/questions/3790889/clojure-lein-read-line-stdin-woes

appears to have some related details to the problem we were seeing with
(read-line) on MacOS; there are some suggestions there.

This, too (the leiningen FAQ):

Q: I don't have access to stdin inside my project.

A: This is a limitation of the JVM's process-handling methods; none of
them expose stdin correctly. This means that functions like read-line will
not work as expected in most contexts, though the repl task necessarily
includes a workaround. You can also use the trampoline task to launch your
project's JVM after Leiningen's has exited rather than launching it as a
subprocess.

Thanks Jan

This is a significant problem, glad to have found it out this evening rather than on the day - I'm sure we will be able to work around it. But the group's contributions and suggestions were more valuable still, so I'd like to thank you all for your patience and your ideas this evening - we're looking forward to sokobanning a great deal now!

Hopefully we can confirm the date for Marick's talk soon. I'm sure there will be a lot of interest - I can't wait.

I've not had success with (read-line) in Clooj either.

[Matthew Gilliard]

No, clooj also seems not to work (https://github.com/arthuredelstein/clooj/issues/90).  Two options I can see:

1/ lein trampoline (this may have fixed it on Arwyn's terminal, but not sure I want to use lein on the day)

2/ (javax.swing.JOptionPane/showInputDialog "Enter your next move")

What a shame that every option seems to be more-or-less broken :(

Thom/Matthew: One thing that struck me on Wednesday guys - have you considered using Light Table instead of clooj? It's a nicer interface, it won't have that 'hang up for a minute every so often' bug (although I'm sure it has it's own bugs) and the auto-evaluation might make things easier for beginners. It certainly fits the bill as a syntax-highlighted editor that comes with Clojure bundled.

For a simple sandbox that just works, the playground is probably best:

http://app.kodowa.com/playground

If you have any problems, I definitely recommend that you delete an existing  ~/.lighttable if you have one.

Thanks Joe - I'm playing around with it now.  Do you know if I can get it to read stdin?
