Just in case, remember that the empty set. is also a partitionâ

What would be good is to publish to MC and mirror to git. Esteban has a script that should be published to do that automatically. For me I will not try to use Git before there is a real effort to hide its complexities. So right now this is MC or nothing. I'm sorry but I do not have the energy to fight with all the mess that can happen between git and MC and git alone. Stef > > â > Yanni > > >

Re: [Pharo-users] OSProcess output to pharo

by David T. Lewis

Yes, that is the correct way to do it. I think that the ConfigurationOfOSProcess for Pharo includes a portion of the CommandShell package, so if you load OSProcess from that configuration you should also get the necessary PipeableOSProcess. That said, I would still encourage you to load the full CommandShell package and explore some of the other things it it :-) ConfigurationOfOSProcess and ConfigurationOfCommandShell have both been recently updated for Pharo.

OSProcess output to pharo

by Lusa Nicolas

Hi, I am doing some work with OSProcess and I want to get the output directly to pharo (i.e. a stream or a byteString would be cool). I have found this on the web http://pharo.gemtalksystems.com/book/PharoTools/OSProcess/ where it's said that if you want access to the output you have to use PipeableOSProcess from CommandShell project. My question is: is still this the correct way to do it or meanwhile in OSProcess something was implemented to handle this specific case? Thanks. Cheers, Nicolas
