<b4283>John Carmack tweeted that "the challenge of Scheme program is to make it run."

<taylanub>The challenge of any programming language is to make programs you write in it run, when you don't know the language. :P And when you do, it's to make them "work" I guess.

<nalaginrut>b4283: hmm? I didn't see it

<nalaginrut>OK, see it, but I don't understand...

<voltagex>anyone awake?

<wingo>moin :)

<garjola>Hello

<garjola>I have a question about parallel execution using (parallel proc proc ...)

<garjola>It does not run in parallel ...

<garjola>it behaves just like (begin ...)

<garjola>At least, only one single core is used.

<garjola>Tested on debian stable on 2 different machines (2 cores and 8 cores)

<garjola>Any hint?

<davexunit>add^_: I remember you being interested in game development with guile. check out this new language: http://strlen.com/lobster

<civodul>garjola: `parallel' is implemented in terms of futures

<civodul>and there's at most 1 future per core

<davexunit>add^_: it has a great feature list. let's aim to match it with Guile. :)

<civodul>garjola: and there were a couple of bugs in Guile < 2.0.7 (?)

<garjola>civodul: GNU Guile 2.0.5-deb+1-3

<garjola>Should I upgrade?

<civodul>yes

<garjola>The behaviour I see is that one single core is used

<garjola>Simple example code

<garjola>(use-modules (ice-9 threads))

<garjola>(define (afunc)

<garjola> (begin

<garjola> (+ 1 2 3)

<garjola> (afunc)))

<garjola>(parallel (afunc)

<garjola> (afunc)

<garjola> (afunc))

<garjola>Any simple way to install a more recent guile on debian? Or do I have to build from source?

<davexunit>build from source. it takes some time but is relatively painless.

<davexunit>you'll have to install a few *-dev packages

<garjola>OK. Thanks

<add^_>davexunit: sorry, I was away. I'll look at it.

<add^_>davexunit: what did you want to do with it? Add stuff to Guile or stuff to Lobster?

<davexunit>add^_: make guile-2d have the features of lobster.

<davexunit>Guile can already do everything that his custom language does.

<add^_>aha

<davexunit>it's just a matter of providing the game specific stuff.

<add^_>Sounds fun :-)

<davexunit>apparently lobster comes with a library for A* pathfinding. that is pretty nice.

<add^_>Right

<add^_>So I should look at the "engine" part?

<add^_>of the list that is.

<davexunit>yeah

<davexunit>Guile covers the first 2 parts.

<add^_>This sounds more interesting than making the RL-lib I was planning on making but have given up on (libtcod has some bindings for guile already apparently)

<davexunit>mostly. minus the speed stuff.

<davexunit>RL-lib ?

<add^_>RogueLike

<davexunit>oh cool.

<davexunit>work on what you'd like. I'm just looking for potential contributors since guile-2d will never get done with just me. :P

<add^_>But finishing the bindings already made should be higher priority..

<add^_>I'll help you if I can :-)

<add^_>I need a clear goal though.

<davexunit>yes indeed.

<davexunit>clear goals are lacking.

<add^_>Well, the list on that page is pretty good for a start

<davexunit>yeah
