/dev/tty" would work (I have not tried it though)

OK, so, tl;dr is it seems you're using Debug.exec(etc) to launch the command, in this case bash, which then gives you an IProcess. You feed further input into the IProcess to get the desired result, and I'm assuming you wire in the console support on your own via stream listeners. So you're not using any of org.eclipse.tm.terminal stuff. I've played with your utility class https://github.com/gorkem/thym/blob/use_cli/plugins/org.eclipse.thym.core... and it also seems to not function if the process being run is expecting the caller to be a TTY terminal (specifically, vagrant up for cdk2b3 not from the openshift-vagrant repo but the standard distribution). It seems to me that Runtime.exec(etc), Debug.exec(etc), the external tools launch configuration, and all other solutions are incapable of being treated as a tty. Only the org.eclipse.tm.terminal stuff is capable of implementing the additional requirements to be treated as a tty... however, I feel that using o.e.tm.terminal on a more regular basis is misguided. For the first part, it becomes difficult to read its output. The user can suddenly get involved in the process by typing things in at inopportune moments. It is impossible to use without the UI, so can't be done in the background, as well as a number of other issues that come as consequences of those. In short, it seems applications requiring a TTY environment are really not that many, and the fact that vagrant-registration requires it at all is very strange. It most likely needs the TTY functionality to accept a password without showing it, but I can't seem to figure out if thats just a guess or not. Either way, I'm going to stick with our current way of doing things, either via Runtime.exec when we want it in the background, ro external-tools launch config when we want the command's output to be shown in a console. - Rob On 12/08/2015 08:02 AM, Gorkem Ercan wrote: For Node.js based tools we needed a fully configured PATH because it is often the case those tools will make calls to other apps.

Rob, Is the Tty issue not separate from the way they use to locate the right way to run. I.e. They assume user has vagrant on path. Removing all need for doing custom which/where etc. /max http://about.me/maxandersen On 08 Dec 2015, at 20:34, Gorkem Ercan <gercan(a)redhat.com <mailto:gercan@redhat.com>> wrote: > > I guess you can deal with /dev/tty.
