Problem launching OCL interpreter example [message #26373]

Originally posted by: aradzivanovich.gmail.com

I'm trying to play with OCL interpreter example, however I did not get
it working yet. I installed eclipse-SDK-3.2M5-win32,
emf-sdo-runtime-2.2.0M5, emft-ocl-SDK-1.0.0M5. When I launch eclipse I
cannot find OCL anywhere in the workbench. There are no errors in the
log, the configuration is given below. Could you please help me to
resolve this problem? Thanx.

Hi, Aliaksandr,

Did you install the antlr.jar library into the plugins/antlr_2.7.2/lib
folder according to the instructions in the plugins/antlr_2.7.2/README.txt
file? If you missed that file, I don't blame you; I don't think there's
any pointer to these special instructions on the download page.

However, in M6 we hope to port the parser off of ANTLR, so this procedure
should be obsolete then.

If you did install ANTLR, then you will see context menus related to OCL in
the editor for *.extlibrary models. To create an extlibrary resource,
choose the "File -> New -> Other..." main menu action and select the
"Example EMF Model Creation Wizards -> EXTLibrary Model" wizard. Follow
the steps (the most useful root element type is Library) to create the
file.

Now, you should see in the context menu of library elements in the resource
(not on the resource or resource set nodes) an "OCL" menu with an action to
open the interpreter console.

HTH,

Christian

Wow, that helped, thanks a lot.
Yes, the ANTLR runtime jar dependency is annoying.
Btw, what technology the new OCL parser will be based on? Will it be
JavaCC or something similar?

I'm glad that worked.

The new parser will be an LALR parser with a BNF-style notation for the
grammar, derived from the Jikes project on SourceForge.

Hi All,
We are currently waiting for the Jikes team to get OSSC approval to include
the new Jikes LPG parser and source in to open source. Until that time the
OCL engine in EMFT will continue to depend on ANTLR. Once the Jikes parser
source and runtime are available in SourceForge we will be updating OCL
engine in EMFT to use the new parser

Thanks
Vishy
