My aim is to create a case insensitive syntax highlighting for the 5 min tutorial.

I did the following changes to the "GenerateMyDsl.mwe2" file
they are:

 fragment = parser.antlr.XtextAntlrGeneratorFragment {
              options = {
            //      backtrack = true
            		ignoreCase=true
              }
            }

fragment = scoping.ImportNamespacesScopingFragment {ignoreCase=true}

fragment = parser.antlr.XtextAntlrUiGeneratorFragment {
            	options = {
            		ignoreCase=true
            		//backtrack = true
            	}
            }

Still the editor does not recognize
hello ID!

Can anyone tell me what's wrong?

I am using the eclipse Xtext/Xtend 2.2.1 Distribution(indigo)(windows 64 bit version) downloaded from the xtext.itemis download page [cannot post links yet Sad

]

If anyone has accomplished this, then please do help me out.

Hi,

there are errors in the workflow (when running it). at least if i try it. it tells me to use

            fragment = org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment {
              options = {
                  ignoreCase = true
              }
            }
      fragment = org.eclipse.xtext.generator.parser.antlr.ex.ca.ContentAssistParserGeneratorFragment{
            	options = {
            		ignoreCase = true
            	}
            }

            }

Are you able to achieve the case insensitivity? And which version of Xtext and eclipse are you using ?

As i said: using the itemis Xtext disto (on mac) and exchanging the std antlr fragments with the ones i posted above. running the workflow works and the editor is case insensitive as expected.

Hi, I am using xtext 2.4.

I replace

/ The antlr parser generator fragment.
fragment = parser.antlr.XtextAntlrGeneratorFragment auto-inject {
options = {
backtrack = true
}
}

to

fragment = org.eclipse.xtext.generator.parser.antlr.ex.rt.AntlrGeneratorFragment auto-inject{
options = {
ignoreCase = true
}
}

and

fragment = parser.antlr.XtextAntlrUiGeneratorFragment auto-inject {}

to

fragment = org.eclipse.xtext.generator.parser.antlr.ex.ca.ContentAssistParserGeneratorFragment auto-inject{
options = {
ignoreCase = true
}
}

, not only doesn't work but it also break my UI editor.
The error red cross becomes un-clickable.

Any help?
