Re: [Pharo-project] did you check in 1.1 how the old browser now support the creation of new method cat

by StÃ©phane Ducasse

Adrian lukas was frustrated because he could not have the last version of the tools like RB, helvetia working in 1.1 and 1.0 I think that this is not something that you can expect. Else we can just stop Pharo now and go to do something else. This is why tools should work on a stable version and be marked tools for Pharo1.0 and brnaching to have tools for pharo1.1 Stef On Dec 20, 2009, at 7:53 PM, Adrian Lienhard wrote: > Version 1.0 is the one to work with, to build and maintain tools for, > etc. Unless you work on the Pharo base system there is no good reason > to use 1.1 at the current time.

Re: [Pharo-project] freetype plugin on os-x squeak v5.0

by John M McIntosh

Ok, I spent a good 4 hours here working through issues. Unfortunately the plugin just assumes an oops reference is a pointer (it's not), and that the squeak word size is (4), it might not be, and the occasional FreeType variable is that an int or long? FreeType defines their own var types so their code isn't confused, but we are... Plus a sprinkling of self cCode: to do magic transformations between oops pointers and instance pointer values transformed to an int, or is that a long... So it will be sometime yet before I get it working with a 64bit VM and 32bit image.

Re: [Pharo-project] Why you need new Method trailers? :)

by Igor Stasenko

A little more. I made an experiment with compressing a method sources into trailers. (you need to file in a changeset (trailer-fixes-extensions.1.cs ) http://bugs.squeak.org/view.php?id=7428 What i did is: CompiledMethod allInstancesDo: [:m | m dropSourcePointer ] It takes a while (compressing sources). A more faster way is to do same in workspace: old := CompiledMethod allInstances select: [ :each | each trailer hasSourcePointer ]. new := old collect: [ :each | each copyWithTrailerBytes: (CompiledMethodTrailer new sourceCode: each getSource) ]. old elementsForwardIdentityTo: new. Before: Image size: 26,192,916 bytes After: Image size: 33,348,596 bytes difference: 7,155,680 bytes. But this means, that your image doesn't have to use .sources file, which is 17,584,724 bytes long as well as .changes 11,745,139 bytes long.. of course, stripping like this, will leave you without method stamps.. :) -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Why you need new Method trailers? :)

by Igor Stasenko

I just created a small changeset http://bugs.squeak.org/view.php?id=7432 which gives me a long awaited feature: to see in a browser, where the heck a given method comes from. If method comes from trait, a method's source tells me , from which one exactly! Open a browser on Behavior clas and select an #addExclusionOf:to: method. Usually you'll see: addExclusionOf: aSymbol to: aTrait self setTraitComposition: ( self traitComposition copyWithExclusionOf: aSymbol to: aTrait) But with my changes you'll see: " From: TAccessingTraitCompositionBehavior " addExclusionOf: aSymbol to: aTrait self setTraitComposition: ( self traitComposition copyWithExclusionOf: aSymbol to: aTrait) in code pane. Same applies to traits themselves for instance, browse TPureBehavior>>isAliasSelector: " From: TAccessingTraitCompositionBehavior " isAliasSelector: aSymbol "Return true if the selector aSymbol is an alias defined in my or in another composition somewhere deeper in the tree of traits compositions." ^(self includesLocalSelector: aSymbol) not and: [self hasTraitComposition] and: [self traitComposition isAliasSelector: aSymbol] There is one problem , which requires better expertise than mine and i need a help from Traits experts: an aliased methods. I tried to find out, how to dig out the aliased method from composition, and get its source to display in code pane .. but no luck. Please give me an advice, how a #getSourceCodeBySelector: method should be implemented for proper handling of aliases. Currently, all aliased methods sources shown using decompiler: Behavior>>methodDictAddSelectorSilently: t1 withMethod: t2 self basicAddSelector: t1 withMethod: t2 Aliased methods, obviously, will require an additional info in source header, like: " From: SomeTrait , originalSelector: #blablba " -- Best regards, Igor Stasenko AKA sig.
