Gaffer for pipeline – part 4 – which version?

When writing pipeline tools, it’s often useful to know which Gaffer version you are running in. In python, the Gaffer.About module is your friend:

import Gaffer
print( Gaffer.About.versionString() )
print( Gaffer.About.majorVersion(), Gaffer.About.minorVersion() )

We also define a (script + ABI) ‘compatibility’ version, that, as we use SemVer – is effectively tied to the milestone + major version:

print( Gaffer.About.compatibilityVersion() )
