pharo for ios and android

I am going to the portland meetup this october and I noticed that one of the items listed is "Smalltalk on iOS and Android" which intrigues me. Is some Guilfoyle-type here writing a VM for these platforms? I was joking with a friend that we should write a vm for ios using the "smalltalk blue book" and it would be fun to learn how vm's work by trying to write sometihng for ios. Is someone already working on this?

It is not mainstream, but has been done by some individuals...

http://forum.world.st/Xcode-projects-for-VM-on-iOS-or-Mac-td5087786.html

One thing to be aware of is that the VM for these platform doesn't come with JIT.

The other is that these platforms are strongly weighted towards event-driven coding style

and the VM currently is not event driven. This has an impact on battery life, and may bump up against rules that terminate a long running process (my understanding of this is limited).

Pharo 8's headless-VM opens up some possibilities towards creating an event-driven VM, but I'm not aware of any immediate plans to do that.

Craig Latta runs Smalltalk images on the javascript vm written by Bert
Freudenberg. Search for Caffeine

Hi--

Yes, https://caffeine.js.org is my main development system these
days, and it runs nicely on my iPhone (or any device, with any web
browser). Caffeine is the https://squeak.js.org virtual machine (which
can run Squeak, Pharo, and Cuis) with Web platform and frameworks support.

thanks,

Ahhh, interesting! I didn't know caffeine even existed! Thank you for sharing.

Thank you Craig Latta. I see there is a caffeine.js.org/pharo
"This page is an early demo of running Pharo 6 with the SqueakJS
virtual machine. It gets far enough now that I think several people in
the Pharo community could fix the rest of the bugs (mostly missing
primitives). "
I'm trying it but it takes rather longer to start than the Squeak page.
By the way, I'm using Firefox on Ubuntu, so what do I type to get, for
example, "print it"?
Ctrl-P is captured by Firefox.

PS: After several minutes, the progress bar for "Loading app Pharo..."
stopped moving.
So I don't think I'll bother trying Pharo on a tablet yet...

Hi Richard--

Ah, I recently condensed the changes file of the Squeak version, so
the first download is much faster. I also think the Pharo 6 image I was
using is much larger than the Squeak one, for some reason. I intend to
update the Pharo image to version 8 soon, anyway.

You should be able to use the normal meta key for your host
platform, it's a bug in the supporting page code in
.../js/squeakjs/squeak.js if not. We can handle command key events
ourselves and then call .preventDefault() on them, to keep the web
browser from chiming in. It should be that Smalltalk handles all of them
except for copy/cut/paste/reload.

Thanks for checking it out!
