This is what I think should work. And yes, I don't think the 'JAVA_HOME' is needed. At least for this command. Alex, let us know if Peter code worked.

#runAndWaitOnExitDo: takes a cull-ed three-arg block with the process, stdout, and stderr; that way you can process stdout and stderr independently. Try this OSSUnixSubprocess new command: '/usr/bin/java'; arguments: #('-version'); redirectStderr; runAndWaitOnExitDo: [ :process :out :err | err inspect ].

Hi Mark, This is what I thought. But it does not seem to work. I tried: OSSUnixSubprocess new command: '/usr/bin/java'; arguments: #('-version'); redirectStderr; runAndWaitOnExitDo: [ :process :outString | outString inspect ]. Or is it the redirectStderr that does not work properly?

java -version outputs to stderr not stdout (also I don't think you need JAVA_HOME /usr/bin/java will do what is needed) On 20/06/2016 15:58, Alexandre Bergel wrote: > On OS X, in a terminal, if I type: /usr/bin/java -version > I obtain: > java version "1.8.0_66" > Java(TM) SE Runtime Environment (build 1.8.0_66-b17) > Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode) > > Using OSSubProcess, do-it-ing the following: > > OSSUnixSubprocess new > command: '/usr/bin/java'; > arguments: #('-version'); > environmentAt: 'JAVA_HOME' put: '/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home'; > redirectStderr; > redirectStdout; > runAndWaitOnExitDo: [ :process :outString | > outString inspect > ]. > > inspect an empty string. > Any idea whatâs going on? > -- Mark

Dragging window only from its title

by Hilaire

Hi, Is it possible to drag a SystemWindow/StandardWindow ONLY from its title, on the top? Currently, the behaviour is: any area of the windows where there is no widget behaves as a select&drag point of the whole window. For some young -- and older -- users of Dr.Geo it can be confusing. I look at it but did not find obvious way to do it but hacking #aboutToBeGrabbed: method. Did I miss something? Thanks Hilaire -- Dr. Geo http://drgeo.eu
