Description of problem:
yum-builddep currently allows you to use yum to get the build dependencies of a
SRPM. This is a very useful tool, but I think adding the ability to get the
build deps from a .spec file would be a great feature. It would allow me, and
other people working with packaging, to get the build dependencies specified in
the spec automatically, instead of manually parsing the spec for the
buildrequires and yum installing them as I do now. The build requires are there
in the spec, so I assume it wouldn't be that hard to add this feature to the
existing yum-builddep tool, then again, what do I know.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start building an RPM from scratch, by getting the source tarball and writing
a .spec file.
2. Add the build deps you know of to the .spec
3. yum-builddep file.spec
No such package(s) file.spec.src
Install the build deps specified in the spec (along with the basic tools
required for building any rpm package) with dep resolving and all so I can
proceed with the packaging.
I know I can create a SRPM from a spec using some rpm trickery, the makefile in
the fedora build system does this, but I'd still like to get the builddeps with
if you have a spec file then you can probably make a srpm out of it and just
pass that to yum-builddep.
Doesn't that achieve the same result?
There's no way to query build dependencies of a spec from rpm-python currently,
that'd need doing first to properly handle it.

Yes. That's what mock does. It's just slower.

I am thinking of implementing this. It should only take a couple lines of code to expose the spec->buildRestrictions field to python.
Actually this has been implemented recently, in F >= 15 yum-builddep can be used on spec files directly.
