Hi all ,

I want to check duplicate file name ,mydocument inside the folder1 ,receive an error for file mydocument in the Folder1.Hence,my problem is :in the same scoping,if there is a dublicate name element ,receive an error.but different scop ,pereviosly file name is used.How can I provide?

Filesystem  Filesystem1  {
	Drive  D{ 
		
	    Folder  Folder1 {   
			File mydocument;  //duplicate  name
			
			File  mydocument //duplicate name
                        archive  =  true  readonly  =  false  ;
			Shortcut  shortcut1  ext  =  DOC  target  = mydocument1; 
			
		}  
		Folder Folder2 {  
			File  mydocument ;  //not duplicate name ,not in the same scop.because,inside the folder2                 
		}  

         Drive C {
                 Folder folder1

Ps:My grammar is below :


import "http://www.eclipse.org/emf/2002/Ecore" as ecore
Filesystem returns Filesystem:
'Filesystem' name=ID'{'
(drives+=Drive (drives+=Drive)* )?
(syncs += Sync (syncs +=Sync)* )?
'}';

SyncElement :
Drive|File|Folder
;

Sync returns Sync:
'sync' name=ID 'source' '=' source =[SyncElement|ID] 'target' '=' target =[SyncElement|ID] ';'
;
Drive returns Drive:
{Drive}
'Drive' name=ID '{'
(contents+=Object ( contents+=Object)* )?
'}' ;
Object:
File|Folder
;
File returns File:
'File' name=ID(
('content' '=' content = STRING )?
&('hQualifiedNameden' '=' HQualifiedNameden = EBoolean )?
&('readonly' '=' readonly = EBoolean )?
&('system' '=' system = EBoolean )?
&('archive' '=' archive = EBoolean )?
&('location' '=' location=STRING )?
&('date' '=' date=STRING )?
&('ext' '=' ext = EXT? )?
) ';' |Shortcut
;
EBoolean returns ecore::EBoolean:
'true' | 'false';
enum EXT :
EMPTY|PNG|TXT |JPG |JAVA | C | BAT |BMP |EXE |COM |DOC |PDF|DOCX|XLS|XLSX
;

Folder returns Folder:
'Folder' name=ID'{'
( contents+=Object(contents+=Object)* )?
'}';

Shortcut returns Shortcut:
'Shortcut' name=ID
('content' '=' content = STRING )?
&('hQualifiedNameden' '=' HQualifiedNameden = EBoolean )?
&('readonly' '=' readonly = EBoolean )?
&('system' '=' system = EBoolean )?

&('location' '=' location=STRING )?
&('date' '=' date=STRING )?
&('ext' '=' ext = EXT? )?
('target' '=' target=[SyncElement|ID]) ';'

In the MWE2 flow, u have something like

fragment = validation.JavaValidatorFragment {
// composedCheck = "org.eclipse.xtext.validation.ImportUriValidator"
// composedCheck "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}

change it to,(basically uncomment the second line)

fragment = validation.JavaValidatorFragment {
// composedCheck = "org.eclipse.xtext.validation.ImportUriValidator"
composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
}

One thing i want to add though, it will check for unique names at all places that you have used 'name=ID'.. So if you dont want that, u need to have a validator instead.

Hi rohit,

I used a validator but I can not check file name .I must use Qualifiedname instead of name =ID ? or I used nested for in the custom validation.I'm confused

Your example says,

File mydocument; //duplicate name
File mydocument //duplicate name

which is a simple name and not a qualified name, hence your grammar using name=ID is correct.
So the simple change to the MWE2 will solve your problem, no need for any validator.


Not sure exactly whether u are looking for a simple name or a fully qualified name, can u please elaborate?

Hi ,

MWE2 not solve my problem:( because check duplicate name for all place.if I change
NamesAreUniqueValidator check all duplicate name (file folder drive names must be unique)

folder mydocument //duplicate name
file mydocument

I wanted : I can check duplicate drive name .I wanted to check Folder and File name in the same scop.for this situation ,I must write custom validation.but my problem is scoping Sad

 
Folder  Folder1 {   //in Folder1 scop ,mydocument1 duplicate name
			File mydocument1 ext =BMP;  
			File  mydocument1 archive  =  true  readonly  =  false  ;
			Shortcut  mydocument1 target = Defaultfoldername ;// not error because Shortcut's name   
			   
			
		} 
		Folder  Folder2 {

                        //not an duplicate name because Folder2's scop
		        File mydocument1 ext =BMP;  
			
			File  mydocument2 archive  =  true  readonly  =  false  ;	
		}

 


I hope ,I can explain my problem.

Hi,

how does your grammar look like? what kind of nameprovider do you use.
if you use qualifiednames it should work
out of the box (using NamesAreUniqueValidator)

Hi Christian ,
I used name =ID ,and ı used NamesAreUniqueValidatorHelper for change default message ,but my problem is not solved.I wanted to check file name and folder name .
I solved for Drive name must be unique with custom validation :

@Check
		public void CheckDrivenamesareunique(Filesystem f){
			
			Filesystem filesystemlist =EcoreUtil2.getContainerOfType(f, Filesystem.class);
			
			List<Drive> drivelist =filesystemlist.getDrives();
			
			@SuppressWarnings("serial")
			Map<String, Drive> firstOccurrenceOfName = new HashMap <String, Drive>() {};
			System.out.println( firstOccurrenceOfName);
			    //the set of duplicate names
			Set<String> duplicateNames = new HashSet<String>();
			    for (Drive t : drivelist) {
			    	  String name = t.getName();
			        //if the name already occurred we have
			        //a duplicate name and hence an error
			        if (firstOccurrenceOfName.get(name) != null) {
			          duplicateNames.add(name);
			          //note the second parameter t
			          //it is essential difference to the first example
			         error("duplicate Drive name",t,FilesystemPackage.Literals.SYNC_ELEMENT__NAME,-1, DUPLICATE_DRİVE,
			  		       t.getName());	
			        } 
			        //otherwise store the name as first occurrence
			        else {
			          firstOccurrenceOfName.put(name, t);
			         
			        }
			    }
			      //now create the error for the first occurrence of a duplicate name
			     // for (String s : duplicateNames) {
			       // error("Duplicate name " + s,FilesystemPackage.Literals.DRIVE__CONTENTS,INVALID_SYCN 
			        		//); //}
	       }//Checknamesareunique
		



my grammar is below :
import "http://www.eclipse.org/emf/2002/Ecore" as ecore
Filesystem returns Filesystem:
'Filesystem' name=ID'{'
(drives+=Drive (drives+=Drive)* )?
(syncs += Sync (syncs +=Sync)* )?
'}';

SyncElement :
Drive|File|Folder	
;

Sync returns Sync:
'sync' name=ID	'source' '=' source =[SyncElement|ID] 'target' '=' target =[SyncElement|ID] ';'
;
Drive returns Drive:
{Drive}
'Drive' name=ID '{'
(contents+=Object ( contents+=Object)* )?
'}' ;
Object:
File|Folder
;
File returns File:
'File' name=ID( 
('content' '=' content = STRING )? 
&('hQualifiedNameden' '=' HQualifiedNameden = EBoolean )? 
&('readonly' '=' readonly = EBoolean )?
&('system' '=' system = EBoolean )?
&('archive' '=' archive = EBoolean )?
&('location' '=' location=STRING )?
&('date' '=' date=STRING )?
&('ext' '=' ext = EXT? )? 
) ';' |Shortcut
;	
EBoolean returns ecore::EBoolean:
'true' | 'false';
enum EXT :
EMPTY|PNG|TXT |JPG |JAVA | C | BAT |BMP |EXE |COM |DOC |PDF|DOCX|XLS|XLSX
;

Folder returns Folder:

Shortcut returns Shortcut:

Hi Christian ,

I wanted 3 level checked.I showed error case on the program.I checked Drive name ,no problem (Drive D1 ->duplicate name error ) My problem is file and folder name.How can I do Sad I am confused

Filesystem
FS
{
Drive D1 {
[color=red]Folder Fo1 {}//Duplicate name  Fo1
Folder Fo1 {}[/color]
}

Drive D1 {// duplicate name for D1	
Folder Fo2 {
[color=red]File Fi1 ; //duplicate name for Fi1 .such as File Fo2 is not a duplicate name 	
File Fi1 ;[/color]	
}
}
//this section not give an duplicate name error because defined in the D2
Drive D2 {
Folder Fo1 {}
Folder Fo2 {
File Fi1 ;	
}
}
}

Hi ,
I must fix below for check duplicate name for same scope? but,I do not understand clusterTypes.Please,Could you help me?I can check same instance same type.but still I check with scop.I must check 3 level.


protected ImmutableSet<EClass> getClusterTypes() {

return ImmutableSet.of(FilesystemPackage.Literals.FILE);
}
private ImmutableSet<EClass> clusterTypes = getClusterTypes();
@Override
protected EClass getAssociatedClusterType(EClass File) {
System.out.println(clusterTypes);
if (clusterTypes .contains(File))
return File;
EList<EClass> superTypes = File.getESuperTypes();
System.out.println(superTypes);
if (superTypes.isEmpty())
return File;
return getAssociatedClusterType(superTypes.get(0));
}

Drive T
	{  
		File file6 ; 
		File file7 ; 
		Folder r9{
			
		}
		Folder File10{  
			File file8;// receive duplicate name error ,in Drive T .
			File file4;    
			
		}
		
		}
		Drive F { 
			Folder file9{
				 
			}
			File file8;// receive duplicate name error but it is in the Drive F so not give an error .

Hi,

i dont get you checking logic:

you want to check only simple names for files and folder?
it does not count in which drive they are contained?

so if you have

drive a {
folder b {
file x1
}
file x2
}
drive c {
folder d {
file x3
}
file x4
}

what should be the names the folders and files should be checked against.
please give me a list

Hi Christian,
Again I show wanted to do on the below program.I wanted to do real file system .
file x1 in the drive a and drive c .it is in the different drive.File x3 in the different folder but same drive so not give an error.
I hope,I can explain my problem Sad How can I provide this case .I am confised .
drive a {
folder b {  
[color=red]file x1  //in the dolder b ,there are two same file name,this case duplicate name
file x1 [/color]
}
file x2
}
drive c {
folder d {
file x3
[color=red]file x1[/color]
}
[code]Folder g{
file x3 
}[/code]
file x4 //duplicate name
file x4
}

Hi Christian,

Folder is in the Drive.so when same folder name in the Drive ,receive an duplicate name.but different Drive ,can be happen same name such as

Drive C
{ Folder folder1{}
Folder folder1{} //duplicate name because two same folder name in the same Drive
}
Drive D{

Folder folder1{} //not duplicate error because,in the drive D
}
If I can correct understand,I used simplenameprovider (name =ID for every meta model name)

I do not understand Defaultdeclarativenameprovider but I am not use .


Thanks & best regards

Alternatively: if you press Crtl+Shift+F3 and search for Model Elements of Type FIle and Folder(Runtime WS) what are the names displayed for your stuff.

If you use simplenameprovider (you may have changed the workflow) then its clear that simple names are compared.

Hi Christian,

I think ,I can not understand my problem:( I used simplenameprovider for meta model element.and then I check duplicate name with custom validation.My aim is count of same file name in the Folder and produce an error for duplicate file name .The same way,count of Folders that have same name ,Folders are in the Drive.So I must found Parent (Drive) and then count of folders in this Drive.Such as
Below scenerio1 ,Drive C and Drive D in the Filesystem.
Scenerio 1:
Drive C{
Folder f1{} //duplicate name
Folder f1{}//duplicate name
}
Drive D{
Folder f1 //not duplicate name because Drive D
}
----------------------------------------------------------
Second Scenerio:
Drive D{
Folder f3{
File f3 //not duplicate name
}
Folder f4{
File f3 //not duplicate name because in the Folder f4
}
}
Now I can Check duplicate name for File Folder Drive but I can Checked every duplicate File's name ,Folder's name.I do not wanted below screenshot taht is in the attachment .I explain my problem above :Scenerio 1 and Second Scenerio.

Now I can checkduplicate name with NamesAreUniqueValidationHelper .My code :


protected ImmutableSet<EClass> getClusterTypes() {
		
		return ImmutableSet.of(FilesystemPackage.Literals.DRIVE,FilesystemPackage.Literals.FILE, FilesystemPackage.Literals.FOLDER);
	}
	private ImmutableSet<EClass> clusterTypes = getClusterTypes();
	@Override
	protected EClass getAssociatedClusterType(EClass File) {
		//System.out.println(clusterTypes);
	
		if (clusterTypes .contains(File))
			return File; 
		EList<EClass> superTypes = File.getESuperTypes();
		System.out.println(superTypes);
		if (superTypes.isEmpty())
			return File;
		return getAssociatedClusterType(superTypes.get(0));
	}

	
}



I bind FilesystemNamesAreUniqueValidator in the runtime module :

public Class<? extends INamesAreUniqueValidationHelper> bindINamesAreUniqueValidationHelper() {
return FilesystemNamesAreUniqueValidator.class;

}


Also ,I remove comment line in the NamesareuniqueValidator :

fragment = validation.JavaValidatorFragment {
// composedCheck = "org.eclipse.xtext.validation.ImportUriValidator"
composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"

}

------------------------------------------------------------------
My problem is not solved this customization(above method) Sad .
1-use FileSystemJavaValidator?

Why do you use simplenameprovider? and not DefaultDeclarativeQualifiedNameProvider?
if you stick with simplenameprovider dont use namesareuniquevalidator at all.
use a custom validation. The Class EcoreUtil2 might contain helpful methods for traversing

Hi Christian,

I examined and tried this example :
http://christiandietrich.wordpress.com/2011/07/16/iqualifiednameproviders-in-xtext-2-0/
but My qualifiednameprovider test program is not work such as this output: (
TestPackage for the package
TestPackage.A and TestPackage.B for the elements

Also .Why do you use Qualifiednameprovider.I do not wanted my program's output such as:

Drive D{
Folder D.folder1 {
File D.folder1.file1 ;
}
}

If I can understand qualifiednameprovider correctly,I must use EcoreUtil2 for traversing the metamodel.

How Can I apply qualifiednameprovider on the my file system domain for check duplicate name(to find elements with the same name) ?

really,I am confused for Qualifiednameprovider Smile

Thanks for your help & best regards

Hääää?

this (parsing) has nothing todo with using a simple or qualified nameprovider.
it just determines how xtext stores the names to the index.
(which is used for the unique validation)

i am not ure what you mean by "output"

Hi Christian,

I want to say program instead of output .Output is a program.I hope,I understand Qualifiedname finally.

Thanks for help & best regards

As said before: the nameprovider does not matter for parsing.

Hi Christian ,

I write custom validation for duplicate Folder name in the Drive.
Fist :I found all Drive
Second:Found all Folder in the Different Drive .show below :


org.xtext.example.filesystem.filesystem.impl.DriveImpl@7f5bbbcd (name: D)
[org.xtext.example.filesystem.filesystem.impl.FolderImpl@5690ff7b (name: Foldername)]
org.xtext.example.filesystem.filesystem.impl.DriveImpl@5f86d10d (name: F)
[org.xtext.example.filesystem.filesystem.impl.FolderImpl@3de9d7c0 (name: Folder1)]

I Wanted :Below output :Drive D has two Folder (names are Foldername) that has the same name,onlly I must checked this case.İn the Drive ,I wanted to count same name folder.How can I do Sad How I can use function ? ( such as getCurrentObject()).I do two for loop .one Drive other Folder,but I can not count same name folder.
----------------------------------
org.xtext.example.filesystem.filesystem.impl.DriveImpl@4504ac5e (name: D)
[org.xtext.example.filesystem.filesystem.impl.FolderImpl@81ba9a2 (name: Foldername), org.xtext.example.filesystem.filesystem.impl.FolderImpl@501dced6 (name: Foldername)]
org.xtext.example.filesystem.filesystem.impl.DriveImpl@68a2ca98 (name: F)
[org.xtext.example.filesystem.filesystem.impl.FolderImpl@4bfaa2c4 (name: Folder1), org.xtext.example.filesystem.filesystem.impl.FolderImpl@33d418d4 (name: Foldername)]

My code :
@Check
public void foldernamechaeck(Drive driveobject){
Drive Drivelist =EcoreUtil2.getContainerOfType(driveobject, Drive.class);

System.out.println(Drivelist);
List<Folder> folderlist = EcoreUtil2.getAllContentsOfType(Drivelist, Folder.class);

System.out.println(folderlist);

EObject parentdrive = getCurrentObject().eContainer();

//System.out.println( parentdrive);




}//foldernamecheck
Thanks & best regrads

Simple iterate and add the names to a list. Pure java this is. Still
the question: why don't you simply use DefaultDeclarativeNameProvider

Hi Christian ,

If I use QualifiedNameProviderprovider ,my problem is solved certainly ?You can give an Example for QualifiedNameProvider.

In addition :

I write a code for duplicate folder:But it give error for every Folder name.My aim is :there arent two folder that has not same name.now I onlly want to check it.not compare folder name Sad

@Check
		public void foldernamechaeck(Filesystem driveobject){
			Filesystem drive =EcoreUtil2.getContainerOfType(driveobject, Filesystem.class);
			System.out.println(drive + "**********");
			List<Drive> drivelist = EcoreUtil2.getAllContentsOfType(drive, Drive.class);
			System.out.println(drivelist);
			List<Folder> folderlist = EcoreUtil2.getAllContentsOfType(drive, Folder.class);
			
			System.out.println(folderlist);
			
			 EObject parentdrive = getCurrentObject().eContainer();
			 
			 int i=0;
			for( Drive d :drivelist)
			{   
				for (Folder f : folderlist){
				
				for(Folder f1 :folderlist){
			if(f.getName() == f1.getName() && i>1){
			error("duplicate File name",f,FilesystemPackage.Literals.SYNC_ELEMENT__NAME,-1, DUPLICATE_FILE,
					   f.getName());
			
			}
					        }//ilk forun
				
				}
				
				i++;	
				}
