Search for case insensitive languages [message #696779]

Hi,

I am trying to implement search (references) for a BASIC variant language (case insentive)

FindAction class use the "DLTKSearchQuery", that creates search pattern. Problem is that th DLTKSearchQuery is creating the pattern as

pattern= SearchPattern.createPattern(element, fPatternData.getLimitTo(), SearchUtils.GENERICS_AGNOSTIC_MATCH_RULE, toolkit);

and

public final static int GENERICS_AGNOSTIC_MATCH_RULE= SearchPattern.R_EXACT_MATCH | SearchPattern.R_CASE_SENSITIVE | SearchPattern.R_ERASURE_MATCH;

From what I noticed further this then goes to BasicSearchEngine who use the indexManager to retrieve potential matches in a case sensitive mode.

What is the easiest way to make the search framework case insensitive?

Hello,

I see now that AGNOSTIC match rule is changed to case insensitive. Thanks for that.

But there is still a place where case sensitive case is used.

	public static SearchPattern createPattern(IModelElement element, int limitTo) {
		return createPattern(element, limitTo, R_EXACT_MATCH | R_CASE_SENSITIVE
				| R_ERASURE_MATCH,
				DLTKLanguageManager.getLanguageToolkit(element));
	}

This is used by ModelElementOccurrencesFinder, causing occurrence finder to be inconsistent with find references for case insensitive languages.
