Re: [Pharo-users] an elegant way to return a result

Yeah, that should be >something aMsg ifNil: [ ^ nil ]< I thought you were referring to something else originally. :) On Tue, Jun 30, 2015 at 1:43 PM, jtuchel(a)objektfabrik.de < jtuchel(a)objektfabrik.de> wrote: > Am 30.06.15 um 13:40 schrieb Peter UhnÃ¡k: > >> Make sense if there's code in between. >> > not sure what you're saying.

Make sense if there's code in between. something aMsg ifNil:[ ^ something aMsg ]. "yay for guards!" "much more code" ^ aNotherResult Peter

Ah, C'mon Esteban! This one is not a question of style: > something aMsg ifNil:[ ^ something aMsg ]. > ^ aNotherResult What the heck ... ??? ;-)))) Sorry, I couldn't resist ;-) See you in Brescia!

Re: [Pharo-users] an elegant way to return a result

by Esteban Lorenzano

all is valid and a matter of style. You can also do this: ^ something aMsg ifNotNil:[ aNotherResult ] ifNil:[ something aMsg ] or this: something aMsg ifNil:[ ^ something aMsg ]. ^ aNotherResult cheers, Esteban > On 30 Jun 2015, at 13:21, abdelghani ALIDRA <alidrandco(a)yahoo.fr> wrote: > > Hi guys, > > what is the best way to express the following : > return (something aMsg) if it is not nil, return somethingElse elsewhere > > I could stil write: > > something aMsg > ifNil:[^ something aMsg] > ifNotNil:[^aNotherResult] > > but it sounds a little bit weird > > Regards. > > Abdelghani

Re: [Pharo-users] an elegant way to return a result

No need to have both if you are returning the receiver. ^ something aMsg ifNotNil: [ aNotherResult ] For example try printing these two lines 1 ifNotNil: [ true ]. "true" nil ifNotNil: [ true ]. "nil" If you are interested in the implementation details I highly recommend to look at the implementation. ProtoObject>>ifNotNil: aBlock and UndefinedObject>>ifNotNil: aBlock.

an elegant way to return a result

by abdelghani ALIDRA

Hi guys, what is the best way to express the following :return (something aMsg) if it is not nil, return somethingElse elsewhere I could stil write: something aMsg Â Â Â Â ifNil:[^ something aMsg]Â Â Â Â ifNotNil:[^aNotherResult] but it sounds a little bit weird Regards. Abdelghani

the little lag we see is due to the bad quality of the table (we did not want to bullet proof the test scenario). ;) Le 30/6/15 11:03, stepharo a Ã©crit : > spread the words ;) > > Interactive table support in Pharo (thanks to the new OS window > architecture) > https://youtu.be/0sIX3YbO-XY > > Thanks Thales for the sponsoring! > >
