Piping find output to an rpm macro

[nicolas.mailhot at laposte.net]

Hi,

I have a set of spec files that perfom the same operations on file lists.
They are bitrotting fast with each spec differing slightly from the other

I'd like to consolidate the operations in a common macro to have a single place to tweak/fix.

So basically I want something like

%mymacro -f outputfile $(find . -iname '*\.foo')

with mymacro defined as

%mymacro(f:) \
%define output_file_list  %{?-f*}%{!?-f*:foo.file-list} \
for file in %* ; do stuff

of course that does not work with rpm failing to parse find output as an argument list

Is there a clean way to make it work? I try very hard to forget everything about rpm macros every time I need to write one

Regards,
