Martin, does this work? I would be interested in seeing it in action.

Re: [Pharo-dev] Torch repo?

Thanks, my main interest is to see how it handles changes and does it use Ring, because monticello changes are horrible, they donât have any hierarchy.

Re: [Pharo-dev] Torch repo?

by Martin Dias

Hi, This one should be more recent: http://smalltalkhub.com/#!/~AnneEtien/RingJET With Anne and Gustavo, we did some work to migrate it to a more recent Pharo (I think to Pharo3). Mostly, moving from Mondrian to Roassal. Probably now it's necessary to move it again, to Roassal2. I don't remember well how the package it should be loaded, and I don't see any Jenkins job. Gustavo may have it more fresh than me.

So, what I can do is to send a sigint to terminate the process and receive the info. But sending "process processProxy sigint." does nothing. By the way I have a warning on the AIOPlugin... Probably I should reinstall my VM. I also try "process flush", but it does not do anything. > > Your #upToEnd call will read the available data from the OS pipe, but it > will not read data that was "written" by the rotopic program, but not > yet flushed out to the OSPipe.
