Hello All,
In a researchproject (called CC/Castle) I have two related grammars. Or
actually two file-extensions: *.Moat and *.Caste. The syntax that is allowed
in a .Moat-file is a subset of that of that in a .Castle-file
I want to use xtext to build a eclipse editor (and compiler) for those two
filetypes. But I run into problems. So some advice is welcome.
I assumed I should create 1 project-set (ccCastle, ccCastle.ui,
ccCastle.generator; as made by the xtext(1.0.1) project-wizzard. And define
both grammars there.
I started by the Moat one. And was able to build a editor for it. Great.
But adding the Castle one didn't worked, at least not as I expected. Writinge
a Castle.xtext file is not a problem but getting it working in the project
I have a file starting with "grammar nl.softwareBeterMaken.ccCastle.Castle with
nl.softwareBeterMaken.ccCastle.Moat" . This seams to work, as the rules that
are "inherited" form the Moat.xtext file a recognized.
To compile it, I copied the file "GenerateMoat.mwe2" to "GenerateCastle.mwe2"
and replaced the strings 'moat' to 'castle'. I was able to run that file as
MWE2-workflow. But it doesn't really work. I tried several
alternatives (including importing the Moat.xtext file instead of the with
statement). and all other things I could think of. Nothings seams to work ..
Some details/errors
* PROBLEM: AbstractCastleProposalProvider can not resolved to a type
(CastleProposalProvider.java)
* PROBLEM: The import
nl.softwareBeterMaken.ccCastle.ui.contentassist.AbstractCastleProposalProvider
cannot be resolved (CastleProposalProvider.java)
* PROLEM: Package 'nl.softwareBeterMaken.ccCastle.castle.impl' does not exist
in this plug-in (MANIFEST.MF)
* BUILD ERROR: org.eclipse.emf.mwe.core.WorkflowInterruptedException: The
generated EPackage references an external EPackage, but 'referencedGenModels'
hasn't been registered.
See below for full log.
Now I'm wondering: is it possible to define two extensions/grammars in 1
project? Or did I change so many items, Eclispe is out of sync (I see some java
file appearing in src/ too. Is that correct, should they be in src-gen?) Are I
mad?
Any advice is welcome. Please ask for details when needed.
Note: I'm not really a java-expert, nor a Eclipse-guru. But I assume I don't
have to, to design a language.
I do no about languages, compilers parsers and stuff. I did use yacc/bison, C
and Emacs in the past. I assume that would to to..
