  python-rpm-spec
  python-rpm-spec is a Python library for parsing RPM spec files.
  tl;dr
  If you want to quickly parse a spec file on the command line you might want to
  give
  rpmspec --parse a try.
  $ rpmspec --parse file.spec | awk '/Source/ {print $2}'
  If you write Python, have no
  /usr/bin/rpm around, or want to do something
  slightly more complicated, try using this Python module.
  RPMs are build from a package's sources along with a spec file. The spec file controls how the RPM is built. This module allows you to parse spec files and gives you simple access to various bits of information that is contained in the spec file.
  Features
  - No extra dependencies other than Python 3
  - Available on all platforms, parse spec files on Windows
  Supported Python versions
  All current Python branches are supported.
  Examples
  This is how you access a spec file's various definitions:
  from pyrpm.spec import Spec, replace_macros spec = Spec.from_file('llvm.spec') print(spec.version) # 3.8.0 print(spec.sources[0]) #{version}/%{name}-%{version}.src.tar.xz print(replace_macros(spec.sources[0], spec)) # for package in spec.packages: print(f'{package.name}: {package.summary if hasattr(package, "summary") else spec.summary}') # llvm: The Low Level Virtual Machine # llvm-devel: Libraries and header files for LLVM # llvm-doc: Documentation for LLVM # llvm-libs: LLVM shared libraries # llvm-static: LLVM static libraries
  Example showing how to retrieve named source or patch files from a spec:
  from pyrpm.spec import Spec spec = Spec.from_file('llvm.spec') # Access sources and patches via name for k, v in spec.sources_dict.items(): print(f'{k} → {v}') # Source0 →{version}/%{name}-%{version}.src.tar.xz # Source100 → llvm-config.h # Or as a list with indices and so on for source in spec.sources: print(source) #{version}/%{name}-%{version}.src.tar.xz # llvm-config.h
  Example showing how to get versioned
  BuildRequires: and
  Requires: out of a
  spec file:
  from pyrpm.spec import Spec spec = Spec.from_file('attica-qt5.spec') # Access sources and patches via name for br in spec.build_requires: print(f'{br.name} {br.operator} {br.version}' if br.version else f'{br.name}') # cmake >= 3.0 # extra-cmake-modules >= %{_tar_path} # fdupes # kf5-filesystem # pkg-config # cmake(Qt5Core) >= 5.6.0 # cmake(Qt5Network) >= 5.6.0
  If you want that the library create warnings during parsing, for example on
  unknown macros, set
  warnings_enabled to
  True:
  import pyrpm.spec pyrpm.spec.warnings_enabled = True # …
  Install
  python-rpm-spec is hosted on PyPI - the Python Package Index. So all you need to do is
  $ pip install python-rpm-spec
  in your virtual environment.
  Alternatively, if you run Fedora, you can enable a copr repository and use the package manager to install a python-rpm-spec as a normal package in your system.
  $ sudo dnf copr enable bkircher/python-rpm-spec # Enable copr repo $ sudo dnf install -y python3-rpm-spec # Install the package
  Dependencies
  Except Python 3 no extra dependencies are required.
  Current status
  This module does not parse everything of a spec file. Only the pieces I needed. So there is probably still plenty of stuff missing. However, it should not be terribly complicated to add support for the missing pieces.
  Development
  If you want to hack on this module you could start with following recipe:
  $ git clone # Clone the repo $ cd python-rpm-spec # Change into the source directory $ python3 -m venv .venv # Create a virtual environment $ source .venv/bin/activate # Activate it $ pip install -r dev-requirements.txt # Install dependencies for development $ pytest # Execute all tests $ pytest --mypy # Run the type checker

  Take a look at the excellent RPM Packaging Guide, especially the section What is a SPEC File?
  Happy hacking!
