Apart from the fact that for some reason, the extensions on MAElement are in the Core package, hence loading just Core gave errors, things looked OK. This is generally useful, small and a very good example of super cool OO design. I would vote to integrate this (<=> and all). Sven

In the past people tried to e.g. add support to monticello to install the original method when an override gets unloaded. But this all breaks down as soon as two packages override the same method. Overrides therefore should be used just for experimental codeâ¦ what i do is to put it on *mypackage-override so I do not forget to find a solution later that does not need it. Marcus

Format shortcut.

by Cyril Ferlicot

Hi, for now we have 2 different shortcuts in hard code on Pharo to format methods: alt + shift + u and ctrl + shift + f. I opened an issue to correct that : https://pharo.fogbugz.com/f/cases/15584/TClassDescription-sourceCodeRefacto… I propose to keep ctrl + shift + f (like in Eclipse). -- Cheers Cyril Ferlicot

Best practice for overwriting methods in other classes

by Kasper Osterbye

I have now twice in two different situations felt a need to "steal" a method in Nautilus and make that method an extension method in my own package. In situation A, I wanted to steal the #buildCommentPane to use a different Morph for class comments, In situation B, Sergio and I needed to redefine #getComments and #addComments:notifying: to fill out behaviour for package comments. What is the kosher way to work and contribute in such situations? I guess it will also pop up in situations outside of Nautilus. -- View this message in context: http://forum.world.st/Best-practice-for-overwriting-methods-in-other-classe… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

New Cog VMs available

by Eliot Miranda

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3354 CogVM binaries as per VMMaker.oscog-eem.1318/r3354 Cogit: Fix the performance regression on x86 in r3308 VMMaker.oscog-eem.1178 through the use of XCHG instruction in CogIA32Compiler>>genPushRegisterArgsForNumArgs:. Since SendNumArgsReg is not live with small arity sends it can replace TempReg. Spur: Fix bad C bug in nextInSortedFreeListLink:given:. The result type must be usqInt, otherwise the list can be wrongly terminated and the second compaction pass can segfault. Change printFreeChunk:isNextChunk: to printFreeChunk:printAsTreeNode:, and use it to implement printSortedFreeList. Firm up the checkTraversableSortedFreeList assert routine to check that the list is traversable from lastFreeChunk, not just firstFreeChunk. Make checkTraversableSortedFreeList robust in presence of empty sorted free list. Slang: Make promoteArithmeticTypes:and: obey C99's promotion rules more closely in an effort to generate more stable sources. Types were flipping between sqInt & usqInt for variables that were assigned both types, so that one generation would produce one type and a subsequent one another (Set/Dictionary hashing?). -- best, Eliot
