specfile_generator

This project is now archived. Its successor is available at https://github.com/befeleme/pyp2spec

This project is about generating specfile through metadata we can get from pypi api, or later with source distribution.

The problems of handling build dependencies or running tests etc. will handle pyproject-rpm-macros

Dependencies

In order to run the specfile generator, you will need this dependencies installed

• Python >= 3.5
• Python modules:
  • jinja2
  • requests

In Fedora, all dependencies can be installed via dnf: sudo dnf install python3-jinja2 python3-requests. Or you can install dependencies via pip into virtual environment.

Generate specfile

$ python3 gen_spec.py hypothesis

$ cat hypothesis.spec

%description
==========
Hypothesis
==========

Hypothesis is an advanced testing library for Python. It lets you write tests which
are parametrized by a source of examples, and then generates simple and comprehensible
examples that make your tests fail. This lets you find more bugs in your code with less
work.

Build source and binary RPM

rpm guide
simpler Fedora specific guide

Things to handle

• rpmlint isn't very happy about our generated specfiles
  • description line is too long
  • name of package
    • name of specfile isn't same as rpm, figure out if the package should be named $name_of_project.spec or python-$name_of_project.spec.
    • normalize text to meet Fedora guidelines e.g. python-Flask -> python-flask
  • in preamble `License:` shortcut of License doesn't need to be same as rpm expect
  • etc.
• check in sdist for tox.ini and use %tox macro for running tests
• test script how big proportion of packages can build especially for C extensions
• move handling of generating file section to rpm macro
