Description Miroslav Suchý 2014-11-05 09:11:32 UTC 
Description of problem:
When you run:
  dnf builddep some.src.rpm
and there is missing dependency, it will just print:
  Error: no package matched
While previously
  yum-builddep some.src.rpm
print nicely:
  Error: No Package found for bar
  Error: No Package found for foo

It would be nice to preserve this functionality, so mock can parse the output and do something about it.

Version-Release number of selected component (if applicable):
dnf-plugins-core-0.1.3-1.fc21.noarch

How reproducible:
always

Steps to Reproduce:
1. create src.rpm with 
   BuildRequires: foo bar
2. compare output of:
  dnf builddep some.src.rpm
  yum-builddep some.src.rpm

Actual results:
  Error: no package matched

Expected results:
  Error: No Package found for bar
  Error: No Package found for foo

Thank you for the report.

I'd just add that it would be even necessary to document the expected output. Otherwise Miroslav would be depending on an undocumented (ie. unsupported) feature. I would introduce a switch or a new command that would have a documented output (not only) for this purpose like Git's plumbing and porcelain functions (http://git-scm.com/book/en/Git-Internals-Plumbing-and-Porcelain).
