Take a look at virtual methods of the <a href="http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.texttemplating.directiveprocessor.aspx" rel="nofollow">DirectoveProcessor</a> class. If I understand correclty, a directive processor can provide class-level code and code for the <a href="http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.texttemplating.texttransformation.initialize.aspx" rel="nofollow">Initialize</a> method of GeneratedTextTransformation.

They looked like this and That should work. Sorry about that, Mike Just notice that in comment #2 your CM system removed the T4 statements. They looked like this

and

E.g. I want to allow writing something like (omitted processor attributes): ... ... where the "For" directive does some ugly XPATH stuff and "EndFor" adds a bunch of closing brackets completing the statement. Because of the bracket stuff I cannot just create class methods. Currently I am even considering doing a preprocessing step to replace the macro like statements... but that does feel wrong. Thanks, Mike Hi Oleg,

where the “For” directive does some ugly XPATH stuff and “EndFor” adds a bunch of closing brackets completing the statement.

Because of the bracket stuff I cannot just create class methods.

Currently I am even considering doing a preprocessing step to replace the macro like statements… but that does feel wrong.

Thanks,
