I just wanted to show that the current method doesn't really save much. Unifying the literals in the image is dangerous, because literal strings are not immutable (and they shouldn't be IMHO). + 10 I would love to have immutability bit. > So that could lead to random errors if a method is modifying a shared string literal. This can of aliasing is bad, it mixes semantics and implementation. I hope that we will be able to fix that with Opal. Stef

Re: [Pharo-project] [Pharo-users] Breakpoints in Pharo
by Mariano Martinez Peck Sept. 27, 2010

Sept. 27, 2010

Thanks for this feature, is really useful. I've just checked latest OB where this should be integrated. I saw a "toogle breakpoint". You area talking about, aren't you? In addition, it would be nice to have such think also in the context menu in the code panel. So you don't need to go to the method and right click there. cheers Mariano On Mon, Sep 20, 2010 at 8:11 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > Did you see that there was a breakPoint class and BreakPointManager? > > Stef > > On Sep 20, 2010, at 12:14 PM, S Krish wrote: > > > > http://skrishnamachari.wordpress.com/2010/09/20/debugger-point-in-pharo-cod… > > > > Unit tests from the browser do this automatically for now.. > > > > Any corrections and inputs are welcome.. it will help in becoming that > bit more productive on Pharo.. > > > > -Skrish > > _______________________________________________ > > Pharo-users mailing list > > Pharo-users(a)lists.gforge.inria.fr > > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > > > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users >

Hello all, What is the state of sound in Pharo? On Linux? I can solve my current problem in various ways, including saving .wav files and playing them elsewhere, but options are always good. Bill

[Pharo-project] is it possible to know the memory occupation (bytes) of an object?
by Mariano Martinez Peck Sept. 27, 2010

Sept. 27, 2010

Hi. I don't know if "memory occupation" is the better name. I just want to know the amount of memory that an object is occupying in RAM. I mean, the amount of bytes. Is this possible ? if true, how ? I would like to do it from both sides: image and VM. I checked both but I didn't find anything. Thanks in advance Mariano

I would appreciate anyone interested in objects-as-methods on Cog pounding on the latest Cog VMs (http://www.mirandabanda.org/files/Cog/VM/VM.r2313/) as this involved substantial changes to method lookup/inline cacheing machinery and there could easily be bugs. The tests run, but they're insubstantial compared e.g. to a full coverage test. best Eliot (repeat with fixed email address: squeakfountation => squeakfoundation) On Sat, Sep 25, 2010 at 9:20 PM, < squeak-dev-noreply(a)lists.squeakfoundation.org> wrote: > > Eliot Miranda uploaded a new version of VMMaker to project VM Maker: > http://www.squeaksource.com/VMMaker/VMMaker-oscog.33.mcz > > ==================== Summary ==================== > > Name: VMMaker-oscog.33 > Author: eem > Time: 25 September 2010, 7:13:51 am > UUID: 733b7c50-b973-4ca0-9831-5c84d09032bf > Ancestors: VMMaker-oscog.32 > > OSCogVM: > Support object-as-method: > Eagerly evaluate the interpreter version of a primitive > to ease the object-as-method implementation and to > improve interpreter performance. > Refuse to enter anything that isn't a CompiledMethod > into the method-lookup cache to avoid open PICs having > to check for valid compiled methods. > Have various places check for isOopCOmpiledMethod: > rather than isCompiledMethod: to allow SmallIntegers to > be used as methods. > Interpreter: > Have various places check for isOopCOmpiledMethod: > rather than isCompiledMethod: to allow SmallIntegers to > be used as methods. > Slang: > support super sends by expanding them at translation > time.

[Pharo-project] Updated Metacello Configurations of OmniBrowser, RefactoringBrowser, OCompletion
by Mariano Martinez Peck Sept. 27, 2010

Sept. 27, 2010

Hi. I just wanted to let you know that I have updated those configurations to work in Pharo 1.1 with their latest versions. All tests are green ConfigurationOfOmniBrowser -> 1.2 ConfigurationOfRefactoringBrowser -> 1.6 ConfigurationOfOCompletion -> 1.2 Now the problem is that I don't know why OCompletion is not working with OB, even when all tests are green :( If someone can help please. Cheers Mariano
