Thanks for the reply. >Â what do you return when you do not find the class I guess you are talking about this block: "[Â self objSuperclassId ifNotNil: [ self objSuperclass lookup: selector ]]". This code is based on the assumption that the entire block returns "nil" when "self objSuperclassId" is "nil". I'm going to check if my assumption was right. - Edouard On Thursday, November 19, 2015 8:17 PM, stepharo <stepharo(a)free.fr> wrote: Hi edouard I will check as soon as I get some time.

Hi, I found "testNilWhenErrorInLookup" indeed, sorry for that. "testRaisesErrorSendWhenErrorInLookup" is still missing though. Maybe the name has changed to this one: testMethodNotFoundRaiseError "(self Â run: #testMethodNotFoundRaiseError)" self should: [aPoint unarySend: #zork] raise: Error. About the lookup method, I should not use "lookup: selector from: anObjObject" at all right? - Edouard On Thursday, November 19, 2015 8:24 PM, stepharo <stepharo(a)free.fr> wrote: I checked testNilWhenErrorInLookup Â Â Â "(selfÂ selector: #testNilWhenErrorInLookup) run" Â Â Â Â Â Â self assert: (pointClass lookup: #zork) isNil.

Re: [Pharo-users] [ANN][EPHESTOS] ChronosManager a time managment tool

by Dimitris Chloupis

Thanks stef , as I said previously, the leds are just a set of images creating an animation, one for each second. I add stuff to it all the time, its far from v1.0 and I have a lot more to add before its version 1.0 , I think in a year probably will reach version 1.0. Today I added alarm sound that fires each time the work time or break time ends. Unfortunately I have not yet found a way to play sound in Ubuntu but it works on both MacOS and Windows :) On Thu, Nov 19, 2015 at 11:05 PM stepharo <stepharo(a)free.fr> wrote: > This is quite cool. > I will have to have a look how you did the led :) > In my game I rescued the LEDMorph but there are a lot uglier :) > > May be you should call it v1.0 > > Stef > > > Le 18/11/15 02:29, Dimitris Chloupis a Ã©crit : > > and here is a video tutorial of how to use ChronosManager > > https://youtu.be/up9cW79S-jA > > "That's one fancy looking UI.
