[Pharo-project] Old configuration options
by nullPointer May 24, 2010

May 24, 2010

I did probe the new developer image verion 1.1, and donÂ´t see options like "easySelection", very useful when works continoously with morphs. That option is lost or is usable in another place? Thanks for the answers. -- View this message in context: http://forum.world.st/Old-configuration-options-tp2229221p2229221.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Concurrency in Pharo?
by Andrei Stebakov May 24, 2010

May 24, 2010

I've been really impressed with what Seaside and Pier were capable of and really wanted to start my new web project with Pharo. I learned that Pharo (and most other open source ST implementations) only use green threads, having no ability to use a multi-core CPU systems. For those of you with experience building mid to heavy load web sites, how do you expect them to scale up on using just one core? Is Pharo a right tool for that? Maybe Pharo (Squeak) has something up its sleeve to handle this, but my heart really sank when I learned about this issue... Thank you, Andrei

[Pharo-project] cant remove accept: method
by Sean Allen May 24, 2010

May 24, 2010

Pharo 1.0 I have a class that has a method accept: that is no longer used. When I go to remove it, I get the message: Possible call to accept: in XXXX Browse? If you do no, it doesn't remove the method. If you do yes, you can only browse, not remove. How can I remove the method short of filing out the class, removing the method and filing the class back in?

[Pharo-project] Cross-fork Metacello configurations
by Sean P. DeNigris May 24, 2010

May 24, 2010

I created a Squeak/Pharo SSpec, which puts the fork-specific world menu code into a Platform package. As I work on the config, I came up against Pharo using Object as a subclass, but the Squeak Inbox requiring (because of the browser tool) MetacelloConfiguration. What would be the best/easiest way to deal with this? If the configs have to be forked, then Metacello really loses value (i.e. #squeak and #pharo). And, I do a lot of work in both forks, so it would be a shame to pick one to upload to and not share work that has already been done with half the users. Thanks.

[Pharo-project] PhD thesis potentially in Smalltalk
by StÃ©phane Ducasse May 24, 2010

Hi guys This team has a Phd position which can be done in Smalltalk. Christophe Dony is an old smalltalk fan in the south of france. He supervised the PhD of Luc fabresse who is working with Noury (and working on Socket for Pharo right now). If you are interested please contact chouki directly.

[Pharo-project] Need someone to test if NBOpenGL works for you on win32
by Igor Stasenko May 24, 2010

May 24, 2010

Hi, i just snapshotted my stuff with various fixes, to make it load cleanly on pharo and squeak images. I'd like you to ask to test and load it and tell me if it works for you. Currently it works only on win32 platform. It could work on Linux, but i didn't had time to port it yet. There is no automatic installation procedure right now, so here what you should try: - first, you need to have VM with NativeBoost plugin + NativeBoost loaded into an image (see http://code.google.com/p/nativeboost/wiki/Installation for instructions) - then load the OpenGL stuff from http://www.squeaksource.com/NBOpenGL in following order: - NBOpenGL-Core - NBOpenGL-Win - NBOpenGL-TrueType - NBOpenGL-Display - NBOpenGL-Morphic i tried the above on Pharo-1.1-11367-Betadev10.05.1.image , which were released recently, and it seems works ok. on squeak/trunk it should also work without problems. Now, if everything went right, then we're ready to run a demo: GLViewportMorph new "useOwnForm: true;" openInWorld This thing should render a TrueType glyphs and animating a smooth zoom of it. Nothing fancy, i just wanna know, if it works for you (and how well). :) As you may know, GPU/OpenGL implementations vary depending on vendor and how old your hardware is, and i don't have all of it at my disposal. Ok.. if you got it running, and it renders the glyphs.. there's one thing left: - save your image and quit (without closing this morph) - start image it should continue working as if nothing happens. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Cannot add halos to selected morph in 1.1 #11368
by HernÃ¡n Morales Durand May 24, 2010

May 24, 2010

If you evaluate BorderedMorph new borderColor: Color red; borderWidth: 10; openInWorld. in PharoCore1.1ALPHA #11368 in Win32 and if you want to add halos to this morph to remove it easily, the halos are added to the world PasteUpMorph and you would need to figure a way to remove it programatically. Cheers, HernÃ¡n

[Pharo-project] #methodClass: answering different in Pharo and Squeak
by HernÃ¡n Morales Durand May 24, 2010

May 24, 2010

Hi, If anyone is using the result of CompiledMethod #methodClass:, in Pharo and Squeak is answering a different object. In Pharo (PharoCore1.1ALPHA #11367) returns an Association and in Squeak 4.1 the CompiledMethod instance which is the historical behavior. This would lead to two different tests where should be the same. Cheers, HernÃ¡n

[Pharo-project] About the Pharo Issue tracker
by Guillermo Polito May 24, 2010

May 24, 2010

Hi! First I may introduce myself. My name is Guillermo Polito and I'm from Argentina. I've been using Pharo for several months with some colleagues that are already here to teach OOP in the UTN university, and i've been suscribed to this mailing list for some time. But it's my first mail here :P. I participated yesterday in the Pharo Sprint in Argentina and there I had my first look at the issue tracker. And well, it seemed to me to be a little messy. There are lots of issues that aren't properly explained, some of them are duplicated, and they are not well organized. It would be nice to use the labels googlecode provides to give them some categorization, so we can browse them in a more intelligent way. Maybe we can split the issues in "modules" (like Collection issues, Compiler Issues, Closures Issues, Networking Issues...) or something like that. That will help in avoiding duplications and looking for issues to solve (because I can look for issues in the modules I know the most). At the moment I will stay looking for issues i can fix or commenting the ones that lacks information :). Regards, Guille
