Re: [mdt-papyrus.dev] OCLInEcore OCL syntax

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi Arnaud

The OCLinEcore syntax documentation just made it into RC3. EssentialOCL 
and Complete OCL might be in RC4.

The Xtext grammar is at 
/org.eclipse.ocl.examples.xtext.oclinecore/src/org/eclipse/ocl/examples/xtext/oclinecore/OCLinEcore.xtext.

Complete OCL (*.ocl) is the language for OCL documents that complements 
existing meta-models. Import the RoyalAndLoyal project
for an example.

The only difficulty is making Ecore tools aware that there is additional 
CompleteOCL. In response to a newsgroup posting I raised 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=347897. After further 
thought I think that it should be possible to auto-install the 
CompleteOCL after just doing a resourceSet.getResource( ... xxxx.ocl ...)
provided CompleteOCLStandaloneSetup has got Xtext warmed up. 
Unfortunately this won't happen for Indigo.It's just possible I might 
manage a FAQ.

No the OCLinEcore editor doesn't reference the Complete OCL; it's the 
other way round.

    Regards
