Re: [Dltk-dev] checking references to external sources

[sec@xxxxxxxxxxxxxxxxxxx]

Hi Alex,

I would like to write UndefinedVariableCheck / UndefinedTypeCheck as  
IBuildParticipantExtensions. For this Purpose I need to walk AST and  
search for variable/type references to check if they have been already  
defined. But I can't find a way to get the AST.

Can I get AST-root from BuildParticipant?

Kind regards,

Martin
