Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours:

http://lists.squeakfoundation.org/pipermail/packages/2010-March/002982.html

Name: System-ar.285
Ancestors: System-ar.284

Add SystemDictionary>>at:ifAbsentPut: as member of the at:[put:|ifAbsent:|ifPresent:] family of supported methods for accessing globals. Used (for example) by Tweak.

=============================================

http://lists.squeakfoundation.org/pipermail/packages/2010-March/002983.html

Name: System-ar.290
Ancestors: System-ar.285, System-laza.289

Three changes:

=============================================

http://lists.squeakfoundation.org/pipermail/packages/2010-March/002984.html

Name: Monticello-ar.379
Ancestors: Monticello-ar.378

Put the newer version check back into saveVersion. It prevents accidental commits when there are newer (unmerged) versions in the repository. The test got lost probably accidentally a while ago; if the removal was deliberate we should make this a preference (I'm too lazy to live without it :-)


=============================================

http://lists.squeakfoundation.org/pipermail/packages/2010-March/002985.html

Name: Tools-ul.207
Ancestors: Tools-cmm.206

- DependencyBrowser gets it's package list from PackageInfo instead of MCWorkingCopy. This way the Tools package doesn't depend on Monticello. But the list of packages are different, that should be fixed.

http://lists.squeakfoundation.org/pipermail/packages/2010-March/002999.html

Name: Compiler-nice.136
Ancestors: Compiler-nice.135

Multiple automatic AmbigousSelector replacement was broken dur to subtle requestorOffset magic. Attempt a correction.

I just made the replacement work, but the second occurence selection just flash , I don't know why.

I do not really understand what I programmed... This is a door open to future bugs.
The requestorOffset inst var in Parser looks like a fragile construction to me.
 I dont understand selectInvisiblyFrom:to: neither...

Not sure what happens if we mix UnsedVariable, AmbiguousSelector and other automatic corrections.

Probably more work on this subject
