Empty Package Names

by Sean P. DeNigris

I noticed that in 4.0 one gets a (resume-able) exception when trying to define a class in category ''. Why? Is it true, as the error message states, that "the Category should not be empty"? One of our key principles inherited from Smalltalk is to treat the programmer like they know what they're doing. Although only a minor annoyance in this case, I often create classes in empty categories specifically because they are throwaways - like a temp directory, and was a bit confused by the debugger popping up, especially before I realized that the exception was resume-able... Also, that made me think about something else... What if the debugger somehow made it immediately obvious whether the exception was resume-able? That could be useful in cases like these to make the user's options clearer. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Empty-Package-Names-tp4803642.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Sorry for the late reply, Stef. Cool that you cleaned AbstractTool and about the second part of my email.. I was indeed wrong!

'/is/this/possible?' asFileReference size

by Roberto Minelli

Hi, I just discovered that if you ask #size to a non-eistent file reference you obtain False. I submitted an issue @ https://pharo.fogbugz.com/f/cases/14862/is-this-possible-asFileReference-si… Cheers, Roby

Re: [Pharo-dev] [Pharo-users] spotter preview

by Tudor Girba

Hi, Hmm. I cannot reproduce your problem. I do this: - Shift+Enter - Spotter is opened without preview - Cmd+P - preview is opened - Esc - Shift+Enter - Spotter is opened with preview - Cmd+P - preview is closed - Shift+Enter - Spotter is opened without preview Does this not work for you in this way?

Hi Thierry, Evaluate "AioEventHandler aioPluginPresent" to check if the plugin is present. Dave
