Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours: http://lists.squeakfoundation.org/pipermail/packages/2016-June/068242.html Name: Morphic-cmm.1188 Ancestors: Morphic-mt.1187 Update the key for #bringWindowUnderHandToFront to Cmd+/ (forward slash). This not only avoids the conflict with Ubuntu and Mac OS keys (sigh), but is a more sensible counterpart to the key which sends windows to the back (backward slash). =============================================

Deferring code update calls ...
by marcel.taeumel 29 Jun '16

29 Jun '16

Hi, there. What do you think about triggering code updates not directly but deferred via a project's deferred UI messages? Here is a change set that does that: thin-update-process.cs <http://forum.world.st/file/n4904046/thin-update-process.cs> Since we do not update the compiled methods in existing process call stacks, update code would be more robust if the respective call stack would be small. For example, this affects code that uses direct inst var accesses like HandMorph >> #handleEvent:. Drawback: If you want to update the system programmatically such as in a deployment scenario, you would have to account for that. Fabio? :D Best, Marcel -- View this message in context: http://forum.world.st/Deferring-code-update-calls-tp4904046.html Sent from the Squeak - Dev mailing list archive at Nabble.com.

Hi All, Looking at squeak source the front page is not rendering. Modifying a project to add a developer doesn't seem to have an OK button. Thanks, Ron Teitelbaum
