Can I use rpm to expand the macros in a specfile?

Question

The concrete example being I have lots of specfiles with Source0: or other Source lines containing macros. How can I have these macros expanded without

Answer 1

Expand macros in scripts

If you're interested in what the scripts in your RPM look like after macro expansion, you can just build the RPM and then get RPM to extract the scripts:

rpmbuild -bi my-package.spec
rpm -qp --scripts my-package.rpm

This works because RPM expands the macros at build-time.
