Yes I think that we should just get better at packaging/loading.... But this package is important so it should be a supported package.

[Pharo-project] Copy from Code::Blocks on Linux
by Schwab,Wilhelm K Sept. 23, 2010

Sept. 23, 2010

Hello all, A frequent problem I encounter: select and copy text from an editor in Code::Blocks; on pasting into Pharo, I get something other than what I copied. Any ideas what might be happening? Are there multiple clipboards on Linux? Could it be a mismatch in format? I'm using Ubuntu. I frequently work around this by pasting the code into gedit and then copying again from there, after which Pharo "sees" it. Bill

[Pharo-project] decompiledSource
by Herve Verjus Sept. 23, 2010

Sept. 23, 2010

Hello All, I would like to port some VisualWorks code into Pharo. The VW current project code uses VW Kernel.decompiledSource that does not seem to be implemented in Pharo...Is there a Pharo method that does the same...Is there someone with an idea ? Thank you... Herve

If so, then it would be nice to see a rich set of calls to functions with different parameter types; ideally it would be in the form of something useful that gets added to Pharo using NativeBoost.

[Pharo-project] HashedCollection showstopper :(
by Igor Stasenko Sept. 23, 2010

Sept. 23, 2010

Unfortunately, when preparing new finalization stuff, i got stuck with HashedCollection which is not yet integrated to Pharo. (Sets with nils also depending on that). In Squeak, old WeakRegistry does the trick by setting a #finalizer: to WeakKeyDictionary instance. Levente, can i ask you to give me a bits, (changesets or mcz packages), which contain HashedCollection refactorings. Or, we can follow an easier path, just extract the delta from two packages, which i found in mail archives: --- I uploaded two packages which contain this change. To load it evaluate the following: (Installer squeakfoundation project: 'inbox') install: 'Collections-ul.310.mcz'; install: 'Collections-ul.311.mcz' --- these are only related to WeakKeyDictionary, made by Levente to speedup old finalization. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] [ANN] JQueryWidgetBox 1.5 for Seaside 3.0
by Torsten Bergmann Sept. 23, 2010

Sept. 23, 2010

Hi there, version 1.5 of the "JQueryWidgetBox" project [1] is available for Seaside 3.0. There are now 32 interesting JQuery widgets wrapped that you can easily use in your Seaside applications. Most noteably we now have a wrapper for mbMenu [2] and uilayout [3]. Also a jQuery Grid is included. I updated some scripts and after some adoptions of existing packages all 81 tests went green again. Thanks to all who helped wrapping the jquery widgets out there!!! To try: ======= Open a clean Pharo 1.1. image and evaluate: Gofer new squeaksource:'MetacelloRepository'; package:'ConfigurationOfJQueryWidgetBox'; load. ((Smalltalk at: #ConfigurationOfJQueryWidgetBox) project version: '1.5') load. You can now load some additional Seaside tools by evaluating: ((Smalltalk at: #ConfigurationOfSeaside30) project version: '3.0.0-rc') load: #('Seaside-Pharo-Tools-OmniBrowser' 'Seaside-Adaptors-Comanche') Now select "Tools -> SeasideControl Panel" to open the control panel. Using the context menu add an WAComancheAdaptor and start it. Now point your browser to http://localhost:8080/browse/jquery-widgets Bye T.

[Pharo-project] Metacello repositories in the future
by Torsten Bergmann Sept. 23, 2010

Sept. 23, 2010

One thing I think that should be discussed at ESUG (sorry I'm not there) is if and how we want to maintain Metacello repositories for the different Pharo versions in the future. I still think about the project/repo dependency issue: An example: we have a repo for Pharo 1.2: MetaRepoForPharo12 it may contain a ConfigurationOfFFI that works for Pharo 1.1. and loads FFI. it may also contain a ConfigurationOfExternalBrowser that requires the ConfigurationOfFFI (usual Metacello project dependency) When Pharo 1.3 comes out we have a new MetaRepoForPharo13 and may just copy ConfigurationOfFFI over since it only loads packages and these packages may be compatible to Pharo 1.3. So far so good ... but: What about ConfigurationOfExternalBrowser, if we just copy it to the new repo the config still points to the "old" ConfigurationOfFFI in the old MetaRepoForPharo12 repo and not to the new one in MetaRepoForPharo13. So we will have to adopt the configs for any new platform version ... and since world keeps spinnning we may also end up with forked configurations.
