Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours: http://lists.squeakfoundation.org/pipermail/packages/2011-February/004320.h… Name: Monticello-cmm.420 Ancestors: Monticello-cmm.419 NOTE: Please close all MC repository browsers before loading this (via the trunk-update process). - Introduced MCFileName for working with Strings in the format [Package]-[author].[version].mcz. - Working toward re-unification of MCFileRepositoryInspector's and MCRepositoryInspector's so that MC browsers on a GOODS or Magma-backed MC repository will behave the same as one backed by a file-system. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004321.html Name: Monticello-cmm.421 Ancestors: Monticello-cmm.420 - Added printing forMCFileName. - Fixed #versionHighlight: for new MCFileName model. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004322.html Name: Morphic-dtl.522 Ancestors: Morphic-mtf.521 Add Debugger class>>morphicOpenOn:context:label:contents:fullView: as dispatch target for opening a debugger in Morphic. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004323.html Name: ST80-dtl.125 Ancestors: ST80-nice.124 Add Debugger class>>mvcOpenOn:context:label:contents:fullView: as dispatch target for opening a debugger in MVC. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004324.html Name: System-dtl.424 Ancestors: System-ul.423 Update #dispatchTo:addPrefixAndSend:withArguments: to flag usage in debugger opening (indicates opportunity for tool builder support to replace this usage). ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004325.html Name: Tools-dtl.299 Ancestors: Tools-nice.298 Evaluating #halt in MVC can result in an extra debugger scheduled for opening in the previous Morphic project. Clean up debugger open by eliminating #isMorphic test from Debugger class>>openOn:context:label:contents:fullView: and replacing with method dispatch to the appropriate MVC or Morphic method. The MVC method no longer schedules an extra open in someone else's world. This fixes some scheduling issues with opening an MVC debugger. However, some additional ToolBuilder support is needed for the MVC debugger, and other scheduling issues may remain (not sure if the problems are due to missing buttons etc, or to some other MVC scheduling issue). ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004326.html Name: Monticello-ul.422 Ancestors: Monticello-cmm.421 Added preamble which closes open MC repositories. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004327.html Name: CollectionsTests-ul.182 Ancestors: CollectionsTests-ul.181 - added a test for #overlappingPairsCollect: to OrderedCollectionTest - recategorized some methods in SequenceableCollectionTest ============================================= http://lists.squeakfoundation.org/pipermail/packages/2011-March/004328.html Name: Collections-ul.430 Ancestors: Collections-ul.429 - fix: #overlappingPairsCollect: didn't work with OrderedCollections =============================================

***IMPORTANT***: Pharo consortium call for letter of intention
by stephane ducasse 01 Mar '11

01 Mar '11

Dear Squeakers We are pursuing an effort to bring Pharo to the next level: we will set up a consortium of pharo users (university, user groups) and industrial partners. Our goal is to build a legal infrastructure that will be able to sustain the development of Pharo and improve its future. As an example, we would like to be able to collect funds (ways as to be determined - we foresee a membership model or moral license) to pay engineering tasks to be performed such as improving the virtual machine, network libraries, better JIT support. To make it short we would like to give a chance to our community to grow and structure itself so that Pharo can get stronger and that risk (truck factor) gets minimized. Imagine that all the Vm gurus suddenly get attracted by Javascript.... We are contacting you to know if your company/research group/individuals would be interested to support such effort. Showing such interest is strategically important for us and INRIA which could also support such effort. Attached is the letter of support that we will collect once signed and scanned ( stephane.ducasse(a)inria.fr / faxed at: 00 33 (0)3 59 57 78 50) The letter is a letter stating that you would be interested depending on the final setup and condition. We will decide together the model but we want to make sure that everybody can participate. Thanks for your support The Pharo Board M. Denker, S. Ducasse, and A. Lienhard

Has anyone besides me had issues where the all in one Squeak 4.2 (or Cog for that matter) doesn't recognize keystrokes properly on Mac OS X Snow Leopard when using the latest RFBServer downloaded from SqueakSource? Thanks. Lawson
