[xtext] Is URI terminal gone ? [message #659059]

Hi everyone,

we finally migrated our oaw xtext grammar to the new TMF xtext 1.0. The
migration had several problems, but didnt become too painful. Took me
like one day.

Now, I wonder what happened to that useful URI terminal. Has it been
renamed, or just excluded from the basic terminals?

Thanks and congratulations for such a beautiful framework :D
Víctor.

Hi,

welcome to the wonderful world of Eclipse Xtext

the replacement for

Import: 
     'import' model=URI ';';

Import : 
  'import' importURI=STRING;

(name of the feature must be importURI)

note you have to do some changes to the workflow too if you want to use global scopes based on imports

...
			// scoping and exporting API
			 fragment = scoping.ImportURIScopingFragment {}
			 fragment = exporting.SimpleNamesFragment {}

			// scoping and exporting API 
//			fragment = scoping.ImportNamespacesScopingFragment {}
//			fragment = exporting.QualifiedNamesFragment {}
//			fragment = builder.BuilderIntegrationFragment {}
...

btw - maybe reading the migration guides might help
0.7.x -> 1.0.x http://www.eclipse.org/Xtext/documentation/1_0_1/xtext.html# migrating_from_0_7
oAW -> 0.7.x http://www.eclipse.org/Xtext/documentation/0_7_2/xtext.html# from_oaw_to_tmf

*Aparently yesterdays response didn't get to the newsgroup. Here it is
again*

Hi Christian,

thanks for your prompt response. I'm afraid im not following you.
I have no clue what you mean with imports, and I don't see how that
helps me having a URI terminal. Maybe I wasn't clear enough.

One of the rules I defined used to be like this:

FromClassName: (fromModifier=FromModifier)? (nsuri = URI)? objectSource
= ID;

Do you suggest that if I replace "nsuri" with "importURI" and "URI" with
"STRING", it would work as it used to?

It seems a bit odd to me the need to modify the workflow and using
specific feature names just to have an URI terminal.

Thanks!
Víctor.

Hi,

in your original project you should be able to find the definition of the URI terminal. Simply copy it to your grammar, or better: write a corresponding datatype rule in order to prevent clashes of terminal definitions.

Hi Alex,

so I assume the answer is: yes, it is gone. Right?

Given that, yes, the only thing I can do is create one myself ;)

Thanks!
Víctor.

Hi,

Yes, it is gone - and - this is why talked on imports - the usual usecase for it where imports.

Hi,

at least this terminal is not defined in the default terminals grammar you usually start with when creating a new Xtext project. You can easily navigate to that grammar using F3 in Eclipse.
