macro with args question

[James Olin Oden <joden lee k12 nc us>]

Hi All,

I have the following macro defined in my build environment

	%revert_script(n:) %{revert_script_dir}/%{?-n*}%{!-n:%{name}}-%{version}-%{release}.sh

The idea is in a package, say its (N,V,R) = (x,1,2), you can do:

	%{revert_script}

and get back:

	/some/path/x-1-2.sh

And if same SRPM has a sub package, say its called x-y, I can do:

	%{revert_script -n x-y}

And get back:

	/some/path/x-y-1-2.sh

This works.  But then say I want to do:

	%{revert_script -n %{name}-y}

I want to get back:

	/some/path/x-y-1-2.sh

But instead I get back:

	error: Unterminated {: {name	
	3<       (empty)
	2<     (empty)
	1<   /var/TKLC/backout/revert.d/
	0</var/TKLC/backout/revert.d/
	error: line 156: /some/path/

I have tried:

	%{revert_script -n %%{name}-y}

But then I get:

	/some/path/%{name-1-2.sh-y}

I try to add expands in various places, and then it looks like the output 
gets completely eaten.

How might I get this to work?  Also, am I perhaps tripping over a bug?
Or are my expectations/thinking buggy (-;?

Cheers...james
