Importing a xtext file to another xtext file in the same package [message #1799660] Wed, 12 December 2018 01:11 Go to next message
Eclipse UserFriend
Hi,
I have two xtext files in the same project. I need to import one xtext file to the other in order to use the grammar definitions declared in it. Could you please tell me the statement I should use to import the grammar file?
Regards!

Is this approach correct?

import "http://www.typefox.io/xtext/langserver/example/OfflineExpression" as OfflineExpression

what do you mean by import the grammar file.

in the workflow:

module org.xtext.example.mydsl.GenerateMyDsl

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {

component = XtextGenerator {
configuration = {
project = StandardProjectConfig {
baseName = "org.xtext.example.mydsl"
rootPath = rootPath
runtimeTest = {
enabled = true
}
eclipsePlugin = {
enabled = true
}
eclipsePluginTest = {
enabled = true
}
createEclipseMetaData = true
}
code = {
encoding = "UTF-8"
lineDelimiter = "\n"
fileHeader = "/*\n * generated by Xtext \${version}\n */"
}
}
language = StandardLanguage {
name = "org.xtext.example.mydsl.MyDsl"

serializer = {

}
validator = {
// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
generateDeprecationValidation = true
}

maybe that is what you are looking for

besides that import "xxxx" is for the metamodel (you might have to generate once to get rid of error in editor)
and with statement is for parent grammar

Is it possible to import one grammar file to the other and use the grammar definitions declared in the first file, in the second file?
For instance,
if there is a grammar definition in file1.xtext as,

KEYWORD_for:
'for'
;

Can I use it in file2.xtext as,

Element:
'start' name=ID KEYWORD_for name2=ID ';'
;

no. you can only inherit from one parent grammar

Hi Christian,

I though it was possible to extend one grammar file with another?

Yes you can extend one with another by changing the with clause.
But you cannot Import a grammar

Hello Christian,

I found out this https://www.eclipse.org/forums/index.php/t/317660 where it is mentioned about importing one xtext file to another, as well as using 'with' keyword. I'm confused. What do these two do and how can I use them practically? Could you kindly explain a simple example?

Regards!

you can introduce a base grammar and use it in another grammar as parent grammar (only one chain of inheritance)

Hi,
I generated a Xtext file using the mwe2 workflow, and tried implementing inheritance: -

MyDsl.xtext:
grammar org.xtext.example.mydsl.MyDsl with org.xtext.example.mydsl.MyDsl2

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

Model:
	greetings+=Greeting*;
	
Greeting:
	'Hello' name=ID '!' type=MyDsl2::List;


MyDsl2.Xtext: -
grammar org.xtext.example.mydsl.MyDsl2 with org.eclipse.xtext.common.Terminals

generate myDsl2 "http://www.xtext.org/example/mydsl/MyDsl2"

MainModel:
	seasons+=Season*;
	
Season:
	"This_is" alt=List;

List:
	alt=('Spring' | 'Summer' | 'Autumn' | 'Winter')
;


When I try to generate Xtext Artifacts in Mydsl.xtext, I get the following error in the console: -

In addition, I do not have a 'Generate Xtext Artifacts' execution option for my MyDsl2.xtext file.

I will also post my mwe2 file below for your reference: -
module org.xtext.example.mydsl.GenerateMyDsl

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {
	
	component = XtextGenerator {
		configuration = {
			project = StandardProjectConfig {
				baseName = "org.xtext.example.mydsl"
				rootPath = rootPath
				runtimeTest = {
					enabled = true
				}
				eclipsePlugin = {
					enabled = true
				}
				eclipsePluginTest = {
					enabled = true
				}
				createEclipseMetaData = true
			}
			code = {
				encoding = "windows-1252"
				lineDelimiter = "\r\n"
				fileHeader = "/*\n * generated by Xtext \${version}\n */"
			}
		}
		language = StandardLanguage {
			name = "org.xtext.example.mydsl.MyDsl"
			fileExtensions = "dsl"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
				// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
				generateDeprecationValidation = true
			}
			junitSupport = {
				junitVersion = "5"
			}
		}
		language = StandardLanguage {
			name = "org.xtext.example.mydsl.MyDsl2"
			fileExtensions = "dsl"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
				// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
				generateDeprecationValidation = true
			}
			junitSupport = {
				junitVersion = "5"
			}
		}
	}
}


Could you please tell me how I should overcome this problem?

Thank you!

This must be related with MyDsl.xtext file having the below part: -
grammar org.xtext.example.mydsl.MyDsl with org.xtext.example.mydsl.MyDsl2


When I changed it to:
grammar org.xtext.example.mydsl.MyDsl2 with org.eclipse.xtext.common.Terminals

It runs fine. But How do I reuse rules of MyDsl2 in MyDsl if I do not have the 'with' clause for MyDsl2?

the langs in the workflow are in the wrong order.
parent dsls have to come first

You are right! I changed the first standard language declaration in the mwe2 workflow to MyDsl2 and the next to MyDsl. I'll paste the workflow for anybody who'd get the same problem: -

module org.xtext.example.mydsl.GenerateMyDsl

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {
	
	component = XtextGenerator {
		configuration = {
			project = StandardProjectConfig {
				baseName = "org.xtext.example.mydsl"
				rootPath = rootPath
				runtimeTest = {
					enabled = true
				}
				eclipsePlugin = {
					enabled = true
				}
				eclipsePluginTest = {
					enabled = true
				}
				createEclipseMetaData = true
			}
			code = {
				encoding = "windows-1252"
				lineDelimiter = "\r\n"
				fileHeader = "/*\n * generated by Xtext \${version}\n */"
			}
		}
		language = StandardLanguage {
			name = "org.xtext.example.mydsl.MyDsl2"
			referencedResource="platform:/resource/org.xtext.example.mydsl/src/org/xtext/example/mydsl/MyDsl.xtext"
			fileExtensions = "dsl2"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
				// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
				generateDeprecationValidation = true
			}
			junitSupport = {
				junitVersion = "5"
			}
		}
		language = StandardLanguage {
			name = "org.xtext.example.mydsl.MyDsl"
			fileExtensions = "dsl"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
				// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
				generateDeprecationValidation = true
			}
			junitSupport = {
				junitVersion = "5"
			}
		}
	}
}


MyDsl inherits from MyDsl2. It is possible to add inheritance to MyDsl2 as e.g:MyDsl3 by adding it before MyDsl2 in the workflow.

Thank You Christian for helping!

Hello again,

I have implemented this method to much complex grammar from which I get a different error when running the mwe2 workflow. I will list down the mwe2 workflow file and the beginnings of the two grammar files that I have and the error that I'm getting at the end.

mwe2 workflow: -

module org.xtext.example.projection.GenerateProjection

import org.eclipse.xtext.xtext.generator.*
import org.eclipse.xtext.xtext.generator.model.project.*

var rootPath = ".."

Workflow {
	
	component = XtextGenerator {

				rootPath = rootPath
				runtimeTest = {
					enabled = true
				}
				eclipsePlugin = {
					enabled = true
				}
				eclipsePluginTest = {
					enabled = true
				}
				createEclipseMetaData = true
			}
			code = {
				encoding = "windows-1252"
				lineDelimiter = "\r\n"
				fileHeader = "/*\n * generated by Xtext \${version}\n */"
			}
		}
		language = StandardLanguage {
			name = "org.xtext.example.projection.Projection"
			referencedResource="platform:/resource/org.xtext.example.mydsl/src/org/xtext/example/projection/ProjectionMainParser.xtext"
			fileExtensions = "projection"

			serializer = {
				generateStub = false
			}
			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
				// Generates checks for @Deprecated grammar annotations, an IssueProvider and a corresponding PropertyPage
				generateDeprecationValidation = true
			}
			junitSupport = {
				junitVersion = "5"
			}
		}

if your project name is example.projection you should use that
referencedResource="platform:/resource/org.xtext.example.projection/src/org/xtext/example/projection/ProjectionMainParser.xtext"
here
if you have ambiguities you have to fix them

i.e, I do not get 'Done' at the end.
However, I know that the below part of the Projection.xtext file (in the sample I have given before) is the reason for this. This problem did not occur before implementing the below part of code: -

offline_expression
   : offline_or_expression=offline_or_expression
   ;

   ;

P.S. The 'identifier' rule without the other parts, did not cause any problem.

Would you kindly be able to help?

Thank You!

here is a minified grammar showing the same problem

offline_expression:
offline_or_expression=offline_method_call_expression;

offline_method_call_expression:
(offline_expression_atom=offline_expression_atom |
(offline_method_call_expression_referenced_name=offline_method_call_expression_referenced_name ('(' ')' | '('
offline_expression=offline_expression (',' offline_expression2=offline_expression)* ')')*));

offline_method_call_expression_referenced_name:
{offline_method_call_expression_referenced_name} ('record' '.')? (identifier=ID) ('.'
identifier2=ID)*;

offline_expression_atom:
(offline_expression_atom_reference_name=offline_expression_atom_reference_name
|
{offline_expression_atom} 'null');

offline_expression_atom_reference_name:
{offline_expression_atom_reference_name} ('record' '.')? (identifier=ID) ('.'
identifier2=ID)*;

you can add

parseGenerator{debugGrammar=true} to the workflow and have a look at the grammar with antlrworks

Hi Christian,
Thank you! I added to the parserGenerator as you suggested. I also added to the same this part :-
 options = {
		backtrack = true
}


Once backtracking is turned on, the code generates without any prior errors. My language works very well now. Is this a recommended measure to take?
