Re: [Pharo-dev] is STHUB slow?

by Hilaire Fernandes

A bit off topic, I took a look yesterday to Moose, I would like to analysis (not clear idea, more like to see what is Moose) the DrGeo source code but I did not went very far. Any tips or pointer you could share related to that? Hilaire Le 21/06/2014 23:51, Tudor Girba a Ã©crit : > Indeed.

Fantastic! Could you send me an archive of this Windows VM to test it and integrate it for DrGeo?

Re: [Pharo-dev] Where is the postcard with syntax?

by Dennis Schetinin

(Another topic I can't miss:) That's I've tried to explain during ESUG 2011: classic + mockist TDD (which is very similar if not identical to BDD) provides a lot of benefits including solid process, flexible designâ¦ and free documentation of course. "Seamless" TDD is really cheap and very efficient in Smalltalk (compared to other development environments, like Java/C# at least), but it still has zero adoption in Smalltalk community, unfortunately. -- Best regards, Dennis Schetinin 2014-06-21 2:09 GMT+04:00 Sean P.

Re: [Pharo-dev] Broken arcCenterX:centerY:radius:startAngle:endAngle:

by Nicolai Hess

I think they are all using the same cairo libs, or at least, the same source version (1.12.6). But rendering with cairo on different OS (linux/windows ...) uses different backends gdi, quarts, xlib, xcb .... I just built a windows vm with new libcairo source (1.12.14) and the bug on stroking arc paths is gone :) 2014-06-21 22:11 GMT+02:00 Hilaire Fernandes <hilaire.fernandes(a)gmail.com>: > SOOooo, the next question is: are the Cairo libs the same on all VMs ? > > Found nothing on git > > Le 21/06/2014 20:00, Hilaire Fernandes a Ã©crit : > > Right!

Re: [Pharo-dev] [Pharo-users] Pharo Video Tutorial

by kilon alios

Thank you Tudor and Esteban . I have uploaded 5 new video tutorials to my playlist that can be found here https://www.youtube.com/watch?v=Ol5ivaEATLQ&list=PLqbtQ7OkSta0ULYAd7Qdxof85… 1) Why Pharo 2) Install Pharo 3) Create a Class 4) Workspace Variables 5) Instance Variables 6) Temporary Variables 7) Inheritance 8) Binary Messages 9) Class Variables and Methods 10) Class and Method Comments 11) Browser Icons 12) Conditions 14) Arrays 15) OrderedCollection and useful methods for collections *16) Dark Theme* *17) Interval* *18) Dictionary and our first GUI with Pharo* *19) Inspector* *20) Deep Into System Browser* these five new tutorials are around 1 hour in total, the total of the Playlist is now 3 hours 26 minutes and growing. I decided to do System Browser 30 minutes long instead of break it down to 5-10 minutes parts cause I think that System browser is better explained in a whole, but I have added music I have created to make the video easier to watch . Hope you find them useful and easy to follow :) On Thu, May 15, 2014 at 7:46 PM, Esteban Lorenzano <estebanlm(a)gmail.com> wrote: > supercool kilon, thank you very much! > > Esteban > > On 15 May 2014, at 18:36, kilon alios <kilon.alios(a)gmail.com> wrote: > > As you may or may not be aware of I have started a series of Video > Tutorials that I upload to YouTube.

Indeed. The Moose jobs started to take 50% or more time since this morning.

Re: [Pharo-dev] SystemWindow instances can't be garbage-collected

by Max Leske

Found the problem, documenting it here in case anybody else ever needs this (remember, this is 1.1.1). Open a debugger (e.g. by evaluating 1/0), then click into the lower right workspace and type something. OCompletion will now have added an entry to the EventManager actionMap with a ContextVariablesInspector instance as the key. There seems to be a cycle there that canât be resolved by the garbage collector, since I wasnât able to find any non weak global pointers (an OContext is referenced by an MessageSend in the action map. The OContext references a morph which is connected to the SystemWindow. Some of those morphs reference the ContextVariablesInspector as their model). Anyhow, it should be safe to send EventManager>>cleanUp: with argument true (actionMaps and their contents get recreated on demand), which will release those entries and allow the garbage collector to collect the SystemWindows, other morphs and the Debugger instances. Note that this is probably not an issue in later versions (e.g. 3.0 doesnât include EventManager anymore) but it might be relevant for later 1.x versions.
