[Dltk-dev] DLTK Builder refactoring

[Alex Panchenko <alex@xxxxxxxxx>]

Hi all,

I have made the builder infrastructure refactoring.
The goal is the ability to use any parsers & ASTs when building the project.

Now IBuildParticipants are called from the org.eclipse.dltk.core plugin.
org.eclipse.dltk.validators.core is used only to launch external validators.

All build participants now should be configured - i.e. the parser step too.
e.g. for ruby:

  <extension
        point="org.eclipse.dltk.core.buildParticipant">
     <buildParticipant
           
class="org.eclipse.dltk.core.builder.ParserBuildParticipantFactory"
           id="org.eclipse.dltk.ruby.buildParticipant.parser"
           name="Ruby parser"
           nature="org.eclipse.dltk.ruby.core.nature">
     </buildParticipant>
     <buildParticipant
           class="org.eclipse.dltk.ruby.internal.parser.RubyTodoParserType"
           id="org.eclipse.dltk.ruby.todo"
           name="Ruby TODO task parser"
           nature="org.eclipse.dltk.ruby.core.nature">
           <requires
                 id="org.eclipse.dltk.ruby.buildParticipant.parser">
           </requires>
     </buildParticipant>
  </extension>

1st one is standard parser, 2nd one is TODO parser and it depends on the 
1st.

Interfaces are changed to the:

public interface IBuildParticipantFactory {
   IBuildParticipant createBuildParticipant(IScriptProject project)
           throws CoreException;
}
public interface IBuildParticipant {
   void build(IBuildContext context) throws CoreException;
}

Regards,
Alex
