get output of a forked process on windows

Hi,

I would like to evaluate a Smalltalk expression in a forked process (i.e. something like OSProcess thisOSProcess waitForCommandOutput: 'pharo Pharo.image eval "SystemVersion current dottedMajorMinor"').
It is doable on linux/mac with OSProcess but not on Windows. Is there another way to do that on Windows? I would prefer to avoid to write to a file.

Thanks,
Christophe

Have you checked the Console version of the windows VM?

PharoConsole.exe is only available for image versions > 50.

I need a solution that works on older image versions.

Thanks for the advice,

Christophe

Hi Christophe,

You have to use ProcessWrapper.

Metacello new

configuration: 'ProcessWrapper';

repository: 'http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo40/main';

load

(as extracted from the baseline of GitFileTree for Pharo4)

Thierry
