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
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.

That's perfect, thank you! Nicolas On Apr 28, 2015, at 5:39 PM, David T. Lewis <lewis@mail.msen.com> wrote:

David, It seems Command Shell doesn't handle REPL applications like the sqlite3 shell, tclsh and goodsrv. How difficult is that to implement, in your view? Alternatively (unless they are the same stuff underneath) how to go about building something like Expect or pexpect? Pierce

Hi Pierce, I'm not sure if I am understanding your question, but please have a look at PipeableOSProcess class>>tkExample. This is an example of having your image talking to a REPL shell, /usr/bin/wish in this case, but probably similar to a sqlite3 shell. The wish shell is a tclsh interpreter with Tk gui, so I expect that is close to what you are trying to do. If you are interested in having your squeak/pharo image be the REPL server, then class ExternalCommmandShell may be closer to what you want. Dave
