Implementation-wise, I'd also vote for raising errors in registerSpecialObject:at: if something other than myObject is already registered, changing to unregisterSpecialObject: at: in order to not unintentionally unregistering something else, and disallow unregisterSpecialObjects:startingAt: ;) Cheers, Henry

[Pharo-project] pharo on sparc solaris

by Tudor Girba

Hi, I would need to run a Pharo RC4 image on a Sparc Solaris station. Looking on the www.squeakvm.org/unix/, I see that there is no VM for such a station, only for Intel Solaris. Unfortunately, I also do not have access to any compiling tools on this machine (it's a server). Can anyone help me with this issue? The machine says it is: $ uname -a SunOS ejpdxa9017 5.10 Generic_142900-03 sun4v sparc SUNW,SPARC-Enterprise-T5220 Cheers, Doru -- www.tudorgirba.com "To lead is not to demand things, it is to make them happen."

[Pharo-project] #recreateSpecialObjectsArray woes

by Igor Stasenko

Hello, i attempted to load Alien-Core package into trunk image, and it failed. One of the problem is override of recreateSpecialObjectsArray method.. I wonder, maybe we should design a nicer API for extending/reserving slots in special objects array, so it won't require overriding this method by every package which needs to extend special objects, like FFI or Alien. Another aspect of replacing this method is , that it makes problematic to unload such package, in case one wants to unload it. So, my proposal is to add a simple API to SmalltalkImage class, and in order to install additional special objects one should do like: MyClass class>>initialize Smalltalk registerSpecialObject: myObject at: 55. Smalltalk registerSpecialObject: myObject at: 56. ... or: Smalltalk registerSpecialObjects: #( x y z) startingAt: 56. upon package unload, a reverse scheme should be supported: MyClass class>>unload Smalltalk unregisterSpecialObjectAt: 55. Smalltalk unregisterSpecialObjectAt: 56. ... or: Smalltalk unregisterSpecialObjects: 3 startingAt: 56. what you think? -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] BrowserEnvironment>>forPackages: aCollection

by Fernando olivero

Lukas, i've noticed that PackageEnvironment instance variable packages is an ordered collection. Could we make it a Set, so when iterating we reduce iterating the same packages twice, Of course just in case a duplicated package was passed as an argument ( which was my case!!!!) Which leads to iterate possibly multiple times through the classes of packages, which significantly increases time to run when using the whole system. Fernando

[Pharo-project] Connectors minimal version into pharo

by Fernando olivero

Great! Once i have something working i'll post the package in squeaksource. I will try to remove the fsm dependency and try to avoid having so many extensions, and have a minimal functionality. Connectors is a full blown system, i just need to draw simple constrained connection between morphs without the graph support.

It never got too much use... partly because the UI parts are not that nicely done, partly because it can only break at the beginning of a method.

[Pharo-project] Automatic generation of abstract methods

by Cyrille Delaunay

Hello, Would it be difficult to generate automatically superclass-abstract methods (with an empty contents) when creating a new subclass? For example, imagine I want to make my own subclass of Collection. As there is a lot of methods in this class and probably abstract methods, it would be cool to see them directly in my subclass without having to look to Collection method one by one (?). I'm probably not the first to ask this question, but in case it is, that's done:)
