Focus on human user

[befeleme]

Till now, most of the work went into enabling a smooth automation. User experience for a human user is much poorer. I'd like to track here the ideas how pyp2spec should behave when a real user interacts with it - ideally define a MVP which can be promoted to the community.

I'm thinking of creating an automode (-a, --automode) that would create a specfile:

• only if the found licenses are valid SPDX identifiers and are allowed in Fedora (the current default)
• invoking import check with -t by default (the current default)
• calling the new macro %_pyproject_check_import_allow_no_modules in %check that ensures buildability of a Python packages without Python modules That would be the default for e.g. Copr builds from PyPI.

The new default would be that pyp2spec creates a specfile which:

• outputs whatever license expressions it found and adds a comment whether they're SPDX-compliant and (optionally) whether that SPDX-compliant tag is good for Fedora
• leaves creating a valid License: field to the packager
• %check invokes the standard %pyproject_check_import with no additional arguments/options
• less CLI options. First candidates to be erased are --description and --summary - either detected or fall back to defaults

Open questions:

• status of %pyproject_save_files '*' +auto - keep it or leave it to only automode and detect the modnames from the package metadata (possible to do, but not immediately - I'll have to start parsing the actual package metadata and stop using PyPI API at some point).

For the manual mode, I'd generate something like this for now:

# Add top-level Python module names here as arguments, you can use globs
%pyproject_save_files ...

Same for the License tag. I'd rather get something like this:

# No license information obtained, it's up to the packager 
License: ...

Or this:

# WARNING, the determined license tag is not allowed in Fedora!
#   "Proprietary" not listed in https://docs.fedoraproject.org/en-US/legal/allowed-licenses/
License: Proprietary AND MIT

than a fatal error.
