Hello Everyone
I'm trying to implement a grammar that should allow to create concrete
models of a graph structure rather than a tree structure.
My requirement is -
For Ex:
(1)
------------------------------------------------------
Pr_dtype id:"pr1"{
name:"pr_dtype_a";
doc:"safwaef";
type:0 ;
}
MessageType id:"mssg_01"{
name:"asdasd";
doc:"sadfasf";
parameters:Parameter type: "pr_dtype_a" ;
}
------------------------------------------------------
which is backed by a grammar of the following pattern:
import "http://q-impress.eu/samm/core" as refn_core
import "http://q-impress.eu/samm/datatype" as refn_datatypes
import "http://q-impress.eu/samm/staticstructure" as refn_staticstructure
import "http://q-impress.eu/identifier" as ident
..
..
MessageType returns refn_staticstructure::MessageType:
'MessageType' 'id:' id=STRING '{'
//parent attrib(s)
'name:' name=STRING';'
'doc:' documentation=STRING';'
//class specific attributes
'parameters:' (parameters+=Parameter)+ ';'
'}'
;
Parameter returns refn_staticstructure::Parameter:
'Parameter' 'type:' type=[refn_datatypes::Type] ';'
;
Type returns refn_datatypes::Type:
CollectionDataType | ComplexDataType | PrimitiveDataType
;
PrimitiveDataType returns refn_datatypes::PrimitiveDataType:
'Pr_dtype' 'id:' id=STRING '{'
'name:' name=STRING ';'
'doc:' documentation=STRING ';'
'type:'type=XSDPrimitiveDatatypes ';'
'}'
;
enum XSDPrimitiveDatatypes returns refn_datatypes::XSDPrimitiveDataTypes:
string='0' | int='1' | float='2' | date='3' | time='4' | boolean='5'
;
..
..
------------------------------------------------------------ --------
So, the problem that I'm facing is that in using the above grammar, the
editor shows the error that:
< mismatched input 'MessageType' expecting EOF > for the model declaration
(1).
and if I alter the sequence of declaration as follows:
(2)
MessageType id:"mssg_01"{
name:"asdasd";
doc:"sadfasf";
parameters:Parameter type: "pr_dtype_a" ;
}
Pr_dtype id:"pr1"{
name:"pr_dtype_a";
doc:"safwaef";
type:0 ;
}
--------------------------------------------------------
errors are :
< Multiple markers at this line
- The feature 'type' of
'eu.qimpress.samm.staticstructure.impl.ParameterImpl@15ee9d9{platform:/resource/Test/test.edifice#//@parameters.0}'
contains an unresolved proxy
' eu.qimpress.samm.datatypes.impl.CollectionDataTypeImpl@1a102 ef{platform:/resource/Test/test.edifice#xtextLink_:://@param eters.0::http://q-impress.eu/samm/staticstructure#//Paramete r/type::/4}'
- Couldn't resolve reference to Type >
< mismatched input 'Pr_dtype' expecting EOF >
---------------------------------------------------------
And yes I'm using TMF XText
Eclipse SDK
Version: 3.5.0
Build id: I20090522-1710
cud anyone suggest a solution.
:)

Hello Sebastian
I just extracted the entire folder of TMF
XText[eclipse-SDK-3.5RC2-xtext-0.7RC2-win32] using winrar. And run the
eclipse.exe.
That's it.
Did I go wrong?
Didn't get any error messages.Ya..but I just set the parent folder name as
TMF_XText while extracting rather than the default
[eclipse-SDK-3.5RC2-xtext-0.7RC2-win32] before extracting.
Ya..2 warnings while running workflow:
error(10): internal error:

Hi Durga,
actually this is not a warning but an error. I guess, the Antlr Parser
has not been generated successfully.
The message indicates some wrong character literal in a terminal rule.
Did you define an empty character somewhere ('') or used two single
quotes inside a character literal?
If you don't mind, please send me your grammar and I'll have a look at it.
Thanks,
Sebastian

Hello Sebastian
You were perfectly correct. Indeed I had left out just '' in one place to
define
an abstract rule with no child inheritances or no assignments.
However, I removed the error.
Infact, I shall send you my grammar along with the intended purpose that I
wish to get out of TMF XText. But Since I have to elaborate what I exactly
need of the grammar, So I'm hoping to send you a detailed mail including
the grammar and the ecore metamodel it has to import as dependency.
I shall try sending it within a day or two.
Thanks a lot.
Durga
