Problem with gitfiletree in pharo 5
by Norbert Hartl Feb. 15, 2016

Feb. 15, 2016

Today I tried to use a pharo 5 image for my project. I installed gitfiletree but could not access my existing git repo I use with pharo 4. In MCFileTreeGitRepository>>#gitBranchs the output for the git command is an empty string while executing the same on the console gives me * master Is this a OSProcess problem? Where to look at to find the culprit? thanks, Norbert

Getting whether specific key is currently pressed
by Jan BlizniÄenko Feb. 14, 2016

Feb. 14, 2016

Hello I would like to ask whether is there any way to directly find out if specific key (shift in my case) is currently pressed. I am trying to implement own multi-selection of elements drawn on Roassal canvas, but I do not receive original MouseClick/Drag/whatever event with shiftKeyPressed, but I receive only Roassal selection event without this kind of information. It would require lots of modifications on Roassal part to forward such info (although it would be possible I suppose), so I am looking for a way to bypass it. Any help is appreciated.

Bloc Alarms: Why Raw Numbers Instead of Domain Objects?
by Sean P. DeNigris Feb. 14, 2016

Feb. 14, 2016

"scheduleIn: 10000" seems much more awkward than "scheduleIn: 10 seconds", and #scheduleAt: is even clunkier - timeInMs - what's that? Unix time? Squeak time? Wherease "#scheduleAt: '3/1/2016 6:55pm' asDateAndTime" is perfectly clear ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Alarms-Why-Raw-Numbers-Instead-of-Domain-Objects… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Recommended VM on Raspberry Pi ?
by Sven Van Caekenberghe Feb. 13, 2016

Feb. 13, 2016

Hi, I have been using the PharoS VM for a Pharo 4 based app on Raspberry Pi (Rasbian). This VM is quite slow. Now that Pharo 5 is Spur based, what is the recommended VM on that platform ? I was hoping to use a faster VM, if that is available. Is anyone having some concrete experience in this area ? Thx, Sven

syntax highlighting / editing STON files
by Peter UhnÃ¡k Feb. 12, 2016

Feb. 12, 2016

Hi, is there syntax highlighting/validation for STON files? I'm currently editing STON file like this one https://github.com/hpi-swa/smalltalkCI#minimal-smalltalkston-template and obviously I would prefer if I knew that I forgot comma/typo/whatever when editing the file and not when the CI build fails. Do we have the technology? :) Thanks, Peter
