Re: [Pharo-dev] Why was #asLegalSelector removed?

by stephan

The way this was handled can be improved. It is sometimes difficult for us not in Lille to find out what is going on. - a specific issue name helps us notice what changes - check where code is used. DeprecationFinder works for that (and should add more repos and team projects). And a specific one: the rename from #asSmalltalkComment to #asComment is problematic. There are 2 kinds of thing casually known as comments: the comment text in a method, and the class comment. The method name should reflect that. Stephan

In latest Pharo 4, inspect "Delay newCodeEnabled" and observe that it is "true". 2. Open the Pharo4Inbox and filter on 14942. 3. Select newest slice and <Merge>. 4. Observe the diff shows all "false" parts removed (it doesn't really get much simpler than this to review). 5. Click <merge> to finish. 6. Observe the image continues to run smoothly. 7. Report your observations on https://pharo.fogbugz.com/default.asp?14942 I need to refresh myself on the fix I did back in 2-Dec. Its languished while some support infrastructure was added to help the system ride-through the change. cheers -ben

Spec terminology: renaming some terms

by Johan Fabry

Hi all, I donât read mails on pharo-dev usually, so sorry if this has been discussed before (and then pointers to the discussion would be appreciated). Last week, in Pharo-users I proposed the Spec terminology changes below. Responses were positive. I am willing to volunteer to do that next week so itâs finished before the 28th and itâs included in Pharo 4. And then I will update the documentation as well. But first I want to know if there are any objections from people on this list. I propose to rename: - ComposableModel to ComposableUI - all the protocols âprotocol-*â to âAPI-*â Other renaming-related comments are also welcome. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
