I'd like investigate how search feature can be implemented with DLTK help.

Could you point me which classes, extension points must I pay attention to?

Hi Sergey,

Sorry for late response.

As I understand you'd like to implement search feature for your language
using DLTK toolkit.

Simple declaration search will be available automatically, after you
specify sourceElementParser for your language, and adding search pages.

For search pages you need to extend org.eclipse.search.searchPages
extension point. For example you could see RubySearchPage.

For more advanced search you need to perform following tasks:

1. Extend org.eclipse.dltk.core.search extension point. It will provide
ISearchFactory interface. With this interface you could specify match
parser, locator, and source requestor.

For example you could see RubySearchFactory or TclSearchFactory classes.

2. Implement MatchLocatorParser is used to parser selected module and
report all possible matches to pattern locator. Please refer to
RubyMatchLocatorParser for example.

3. Implement SourceIndexRequestor is used to report all needed things to
DLTK Index. Default implementation (SourceIndexerRequestor) report model
elements. For example for TCL we make some advanced thinks here. Please
see TclSourceIndexerRequestor class for example.

And whats all.

Andrei.
