Today I triaged a bug in CodePanel by downloading image versions 50600 50590 50595 50597 and 50596 and installing NewUI from the catalog browser to find out that it was broken by a change in 50596. With PharoLauncher it took me about 5 minutes, just long enough to wonder if I should automate this further, and just short enough to not bother. Stephan

On my machine it doesn't seem to change anything in 50617. As soon as I start typing, the subscriptOutOfBounds happens. What changed in filters? Stephan

Call for Spec Examples

by stepharo

Hi guys I started to group the Spec material in a github pillar project. I should add the dynamic chapter of stephan. Julien is preparing some examples and what would be good is if you have some tips and tricks we could add a chapter to collect them. https://github.com/SquareBracketAssociates/BuildingUIWithSpec Stef

Re: [Pharo-dev] wrong method trailer kind

by Tudor Girba

Ok, but still I do not understand how did the methods end up having a problem with the method trailer? And what can we do about it?

Then Dan Ingalls added the ability to not have source files at all but just to have named temporary variables. he added a compressed version of the temp names in bytes tacked on at the end of a method, replacing the source pointer.
