Pharo 7 on SqueakJS (demo)

by Pavel Krivanek

Hi, with some tweaks mostly related to FFI and fonts, we are able to run Pharo 7 on SqueakJS VM. Do not expect blazing performance. Currently, it is about two orders of magnitude slower than the native VM. https://pavel-krivanek.github.io/pharo/pharo.html Cheers, -- Pavel

Esteban's ChangeLog week of 14 May 2018

by estebanlm＠gmail.com

Hello! This is my weekly ChangeLog, from 14 May 2018 to 20 May 2018. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=14/5/2018&to=20/5/2018 ChangeLog ========= 18 May 2018: ------------ * The strategy of "just copying" dependencies when they are available has some limitations: we need to copy also dependencies we may not want. I will review these copied libraries (for now: cairo, libssh2 and libgit2) to minimize them. This means I need to review versions and maybe compile them myself and put them in the repository. Still, is not the best approach possible, but is the way I'm finding to move on for now... we'll see how it goes. 17 May 2018: ------------ * I've been working on the Windows 64bit PharoVM compilation. I needed to hack a lot and take decisions I'm not proud of them, but well... after one week work (and six months trying), now I have a 64bit VM with all dependencies compiled. *But!*... I cannot call it a victory. Dependencies are still not working properly (libgit2 and cairo, at least). So now the painful debug phase restarts. 16 May 2018: ------------ * I found an important leak when using OSWindow and SDL2, so I spent some time fixing it (or at least, trying to fix it). I made two PRs that should fix the problem: [https://github.com/pharo-project/pharo/pull/1368](https://github.com/pharo-… and [https://github.com/pharo-project/pharo/pull/1369](https://github.com/pharo-… 15 May 2018: ------------ * Spent the day resuming work on win64 VM for Pharo. I decided stop trying to fight the dependency building hell and start over with a different approach: we will build the vm using the available libraries in cygwin64 (when possible) and we will use a separate project to build dependecies when we need something cygwin does not provides. While this approach is far from being perfect, it will allow us to move on. Anyway... I spent most of the day getting my cygwin environment to work, but I managed to advance a bit anyway. cheers!

If I open it via CLI with either a fresh stable VM or the one for Pharo 7 that launcher dl-ed, it works fine, but if I drop the image file onto the same VM (which is what I did in my OP), it doesn't open. Anyway, no big deal if I can open it somehow - just strange! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

I'd say it looks more like an FFI bug than a Freetype bug, but we should investigate it... On Sat, May 19, 2018 at 3:26 PM, Sean P.
