[Pharo-project] Fwd: [Vm-dev] New Window VM (Closures, FT2Plugin, Large Cursors)
by Damien Cassou March 7, 2009

March 7, 2009

---------- Forwarded message ---------- From: Andreas Raab <andreas.raab(a)gmx.de> Date: Sat, Mar 7, 2009 at 8:38 AM Subject: [Vm-dev] New Window VM (Closures, FT2Plugin, Large Cursors) To: The general-purpose Squeak developers list <squeak-dev(a)lists.squeakfoundation.org>, Squeak Virtual Machine Development Discussion <vm-dev(a)lists.squeakfoundation.org> Folks - Since I was in VM building mode today I figured I might as well make a new Squeak VM. There is some interesting new stuff in it: * Closure support. This VM is based on VMMaker-dtl.116 meaning it includes support for the closure bytecodes. I have verified it by both running a Qwaq image on this VM and and a converted closure image on our Stack VM (this is useful since the Stack VM will die a horrible death something goes wrong in the process). It worked fine both ways which means that I no longer need to switch VMs (yay! ;-) * Experimental large cursor support. Try the following for fun (but don't do it in an image you care about): Â Â Â Â cursor := Cursor extent: 128@128 depth: 32. Â Â Â Â cursor offset: -64@-64. Â Â Â Â cursor getCanvas Â Â Â Â Â Â Â Â fillOval: cursor boundingBox color: (Color white alpha: 0.1); Â Â Â Â Â Â Â Â frameOval: cursor boundingBox width: 4 color: Color red; Â Â Â Â Â Â Â Â line: 62@64 to: 66@64 width: 1 color: Color blue; Â Â Â Â Â Â Â Â line: 64@62 to: 64@66 width: 1 color: Color blue. Â Â Â Â Cursor classPool at: #NormalCursor put: cursor. This changes your normal cursor to be a 128x128 pixels large, translucent cursor. * FT2Plugin. The build includes an external FT2Plugin that has no dependencies on extra DLLs. The downloads are in the usual places: http://squeakvm.org/win32/release/SqueakVM-Win32-3.11.1-bin.zip http://squeakvm.org/win32/release/SqueakVM-Win32-3.11.1-src.zip A closure image (for those interested): http://squeakvm.org/win32/release/Squeak-3.10.2-Closures.zip Note that I consider this an "alpha" version since there is a goodly bit of new and untested stuff in it. I'm in particular interested in finding people to test large cursor support and the FT2Plugin. Feedback is highly welcome. Cheers, Â - Andreas -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] how to query for methods with compilation failures?
by Sebastian Sastre March 7, 2009

March 7, 2009

hi there, I've ported an app to pharo+seaside 2.9a2 it's starting to work abut in this stage I have N methods with compilation failures. For instance, what once was SUFunction now is JSFunction an others like that I wish those methods listed so I can fix one by one in one rant instead of [self test; annoy; fix] timesRepeat: N :) any ideas? thanks, sebastian

[Pharo-project] Application based preference (external)
by CÃ©drick BÃ©ler March 6, 2009

March 6, 2009

I was just wandering if we could use the framework in development to deal with preference/settings on an application base. I mean, for my app, I have say 10 parameters (implemented class side) and I want to collect them so as build a preference editor in seaside (or whatever, aida, morphic...). How would you do ? use the new preference stuff (maybe another class - ExtAppPreference) or something else... Thanks -- CÃ©drick

[Pharo-project] OB
by Alexandre Bergel March 6, 2009

March 6, 2009

Hi David, it seems that your last improvement of OB (especially the one defining the width of the mercury input field) does not work properly. The input field is above the buttons.

[Pharo-project] Cog Closure Compiler
by Lukas Renggli March 6, 2009

March 6, 2009

Hi, I finally found out where to get the image level code for the Cog Closure Image. http://www.mirandabanda.org/files/Cog/Closures0811/Bootstrap/ I used the latest Squeak 4.0 VM from John and I tried to load the change-sets into the latest Pharo, as well as into the latest Squeak 3.9.1. In both cases it breaks pretty early on. It is easy to add empty dummy classes that the script tries to patch (e.g. DecompilerTest) but then there are dozens of undeclared variables reported on transcript and the file-in eventually dies. The fact that debugger, compiler, browser and compiled methods are then in a strange state doesn't make it easier ... Has anybody had more success with this? Anybody willing to help making this thing work in Pharo? I desire fast closures so badly ... ;-) Lukas -- Lukas Renggli http://www.lukas-renggli.ch

Hi, is there a way to get the #ifNotNilDo: behavior to write compatible Squeak and Pharo code? Bye -- Damien Cassou http://damiencassou.seasidehosting.st

[Pharo-project] can't load seaside 2.9a2
by Sebastian Sastre March 6, 2009

March 6, 2009

hi there, first of all thanks for making Pharo. I can see there is a lot to do but I'm so glad to see an open smalltalk evoluting in such a direction. I wanted to give a try with a web app I'm porting to seaside 2.9a2 but it won't load (I mean seaside 2.9a2). It's complaining about problems related to MIMEDocuments. Looks like the ones in squeak 3.10.2 are first class objects instead of strings, the mime database and such. I'm missing some update? thanks and all the best sebastian
