Hi,

I've got a problem with symbols in TCS and i don't know why.

I've got a template like this :

template PrefixDecl
: "PREFIX" prefix <no_space> ":" "<" <no_space> uri <no_space> ">"
;
which is supposed to parse a line like this one :
PREFIX truc: <much>

and in symbol section
symbols {
colon = ":" : leftNone, rightSpace;
gt = ">";
lt = "<";
...

But i've got this error during execution
[am3.loadModel] Error: 1:12: expecting COLON, found ':'.
[am3.loadModel] Error: 2:11: expecting COLON, found ':'.

Is there anyone who can tell me why the symbols colon is not recognize as
":"

Regards

Hi,

Can you please make sure there is no error or warning (e.g., lexer
ambiguity) message when you compile your TCS model?

Hi,

I've resolved my problem. It wasn"t an error in the TCS but a
configuration problem for the TCS2JAR build when using the TCSToolkit. So
i use another TCS2JAR.xml directly in the project directory, adding
ebnfinjector.jar, vm.jar and antlr in classpath. Now it works fine.

Question on TCS2JAR. Is there an updated version that takes account of the
new atl location. When i used this build to create a jar file, i've got
errors coming from bad references to older atl location (org.atl. ...
rather than org.eclipse.m2m.atl. ..)

Yes, there are updated versions of the jars (especially ebnfinjector) in
the ATL CVS:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2m/org .eclipse.m2m.atl/plugins/org.eclipse.m2m.atl.engine/lib/?roo t=Modeling_Project
