Re: [Pharo-users] profStef missing executeMethod

by ClÃ©ment Bera

Ok well one will fix ProfStef one day, probably before the Pharo 3.0 release. To insert this code in your image and finish ProfStef, open the class browser (right click on the background, then class browser is the first context menu item), then right-click on the packages (left list), click on 'find class...', write 'Object' or 'ProfStef', press enter, then add a method with exactly this code (copy and past it): *executeMethod*: method ^ self withArgs: #( ) executeMethod: method Then ProfStef should work. Updating ProfStef was in the TODO list for Pharo 2 summer release, but I guess one forgot this method. For Time now, you have: Time now printString ===>>> print in 12h mode Time now print24 ===>>> print in 24h mode The object is the same, just the printing method is different. By the way, a quick trick, when you look for senders or implementors or a message, write the selector anywhere, highlight it with your mouse, then right-click on it, click 'extended search...', then click 'senders of it ...' or 'implementors of it ...' so you can know directly who implements/sends this message without looking into all the class in the class browser. It helps a lot understanding code. Pharo by example is good with Pharo 1.4. More recent version of Pharo may be a little different from what is in the book, however most of it should be very similar. The new book, Deep into Pharo is up to date with Pharo 3.0 but covers only advanced aspects of Pharo. Enjoy working with Pharo :) 2013/10/27 Charles Hixson <charleshixsn(a)earthlink.net> > Hello, > Thanks for the response.

Hello, Thanks for the response. However being as I'm of the level of experience where using profStef it's probably a poor idea for me to even TRY to fix things.

Re: [Pharo-users] profStef missing executeMethod

by ClÃ©ment Bera

Hello, I think #executeMethod was a shortcut for method without arguments of the method #withArgs:executeMethod:. I missed it too, so I guess you can add a bug report, create and commit a slice and lastly it will be integrated in Pharo in the next few days. #withArgs:executeMethod: is implemented in ProtoObject, but we take care not to have too many methods there. This kind of facilities are usually in Object (For example, #isNil is in ProtoObject, but #notNil which is a facility for 'isNil not' is in Object). So I guess what you miss is: Object>>*executeMethod*: method ^ self withArgs: #( ) executeMethod: method Best, 2013/10/26 Charles Hixson <charleshixsn(a)earthlink.net> > I'm using: > > Pharo2.0 > Latest update: #20625 > > I'm at "Reflection continued > > When I do the command to go to the next lesson: > ProfStef default executeMethod: (ProfStef lookupSelector:#next). > > I get the error: > ProfStef(Object) doesNotUnderstand: #executeMethod > > When I browse to the class in the system browser, ProfStef doesn't have an > executeMethod object. > I also checked Object and ProtoObject,just to be sure, but neither of them > listed an executeMethod either. > > P.S.: I also looked at the Class Methods, though default looks like it > returns an instance, so that didn't feel reasonable. > > Where is executeMethod supposed to reside, and was this an intentional > change that just hasn't propagated yet ('m guessing the removal of the > method) or is something wrong with my image?

profStef missing executeMethod

by Charles Hixson

I'm using: Pharo2.0 Latest update: #20625 I'm at "Reflection continued When I do the command to go to the next lesson: ProfStef default executeMethod: (ProfStef lookupSelector:#next). I get the error: ProfStef(Object) doesNotUnderstand: #executeMethod When I browse to the class in the system browser, ProfStef doesn't have an executeMethod object. I also checked Object and ProtoObject,just to be sure, but neither of them listed an executeMethod either. P.S.: I also looked at the Class Methods, though default looks like it returns an instance, so that didn't feel reasonable. Where is executeMethod supposed to reside, and was this an intentional change that just hasn't propagated yet ('m guessing the removal of the method) or is something wrong with my image? Also, if I wanted to include it into ProfStef, what would the method look like? -- Charles Hixson

Re: [Pharo-users] Pharo 2.0 with RFBServer with -headless

by Srikumar K. S.

Hi Norbert, I don't think it is RFB's fault either. I did give the complete steps I did. Perhaps just a wait loop after each of the steps is all it takes, 'cos since I did those steps using the local vm by hand before the "save and quit". I know how to wait for RFBServer to start (1), but I'm not sure how to wait for the load to finish or whether I need to. Anyway, I'm happy now since RFB is running fine with the manually created image.
