OSProcess example
Locked

Hi,
I am trying to trigger a ruby script from within Squeak. I loaded OSProcess but none of the examples are working. Are there any pointers on how to use OSProcess correctly. I am using a 3.8 stable version.

Hello Prashanth, You can find some general information here: http://wiki.squeak.org/squeak/708 OSProcess requires a special plugin for the VM. If OSProcess is not working, it is possible that the VM you are running does not contain this support. Can you say what operating system you are using, and if possible what VM? I will mention also that if you want to interact with a ruby script from Squeak through pipes (in other words, read and write the standard input and output streams from the ruby program), then you will also want to load package CommandShell and use the class PipeableOSProcess.

Dave,
Thanks for the pointer. Somehow, I missed the VM part. I will investigate. I am on the road today whole day. Will try this tomorrow (Wednesday ) and report back.

Dave,
I am trying to trigger a ruby script which posts to twitter. My environment: OS: Windows 7 Squeak version: 3.8 Squeak VM version: 3.7.1 (compiled using gcc)
(also tried it on the latest VM 4.1.1)
I will continue to investigate. Any pointers on what I am doing wrong will help me. Thanks in advance. Regards,

Hi Prashanth,
The VM that you are using does not include the necessary plugin support for OSProcess. There are some newer VMs that do have this support, for example this one: http://www.mirandabanda.org/files/Cog/VM/VM.r2499/cogwin.zip But this will not work with Squeak 3.8. Since you are using a Squeak 3.8 image on Windows, I suggest that you try using the Process Wrapper package instead of OSProcess. This is a package written by Levente Uzonyi that should do exactly what you need. You can find it on SqueakSource: http://www.squeaksource.com/ProcessWrapper http://squeaksource.com/@A3eR3kgBj6bF6Btx/uXSs3tq9 If this does not work for you, please write again and I will try to find an OSProcess plugin for Windows for you.

Dave,
Thank you very much. ProcessWrapper by Levente Uzonyi works for me. I am able to accomplish what I want. Regards, On Wednesday, October 12, 2011, David T.

Dave,
I must add that I saw an error pop up while downloading the plugin (not the core mcz). All I saw in the debugger stack was that "default" was giving problem I was in no mood to dive in, so at random picked up an older version (ProcessWrapper-Core-ul.27.mcz) to load everything again. And it worked. This may serve as part of documentation. Regards, On Thu, Oct 13, 2011 at 5:40 PM, David T. Lewis <[hidden email]> wrote:
