Getting type information from AST [message #1765086]

Hi,

I'm working on a plugin for C code generation which is based on the CDT.
I'm trying to retrieve type information for return values and parameters for functions.
Therefore I get IFunction instances from the AST and use the type information for the IParameter instances and the return type of the function itself.

The problem I currently have usign this method is, that I cannot get the original string of a type but only the string that is returned by getName of ICompositeType or ITypedef.
If the type was defined using a #define directive (e.g. #define TYPE_CHAR_P char* ), that name is no retrievable. getType returns a type that already resolves to char* but I would need TYPE_CHAR.

Is there a way to get the original string?

Regards
Marcus

Hi Marcus, I don't know the answer to your question. The CDT does support browsing the macro expansions, so I would suggest starting by looking at how that code works and see if you can apply it to your case.

HTH for a start.

Hi Jonah,

thanks for the advice.
I will start to take a look at the AST Visitor. This should be usable to retrieve the missing information.
