BlockClosure folding

by HernÃ¡n Morales Durand

I think I saw a coding pattern a while ago that allows you to do the following: cond1 , cond2 , cond3 , cond4 And providing a kind of folding selector condition #and: you would get: [ cond1 and: [ cond2 and: [ cond3 and: [ cond4 ] ] ] ]. for example: conditions := [ : each | each firstName = 'Boca' ] , [ : each | each lastName = 'Baret' ] , [ : each | each fullName = 'Virgasia' ]. such that the following assert is met: self assert: conditions equals: [ : each | each firstName = 'Boca' and: [ each lastName = 'Baret' and: [ each fullName = 'Virgasia' ] ] ]. Any ideas or pointers? Cheers, HernÃ¡n

but is true is not "recommended", I should phrase what is there better ;) Also VM should work anyway... but Ubuntu 16.04 is pretty old, I am no surprised it is not working properly (and no idea if we can make it work easily...

Thanks Esteban, I'm on Ubuntu 16.04. Where did I miss the "pointed in the download page"?

Re: pharo image and vm

Hi, which is your distribution? In anycase, as pointed in the download page, preferred way in linux to install the vm is through openbuildservice: https://software.opensuse.org/download.html?project=devel:languages:pharo:l… can you try one of that and tell us if problem remains?

pharo image and vm

Hi, I downloaded a new pharo from https://files.pharo.org/get-files/90/pharo64.zip https://files.pharo.org/get-files/90/pharo64-linux-stable.zip When I start up the image with the VM, I get "Your VM is too old for this image. Please download the latest VM" None of the shortcut keys seem to work. Something like <ctrl>-c does nothing. Does this have something to do with the incorrect VM? What am I missing here?

Re: Detecting keystrokes in Spec2 input fields

by stephane ducasse

in general this is not a good style to set color directly. Using style will make sure that your components will support themes in a simpler way. Because you will not have to have case statements and check all the place where you change color.

Thanks Esteban Iâve made it work based on your example.Â As you said I didnât need registerEvents.Â My original block just called a method that I used for trapping with the debugger to investigate how it worked.
