# GitHub tag archive rather than the PyPI sdist: the sdist ships tests/ without

%global _description %{expand:
pdf_reports turns a template into a PDF. It renders Pug or HTML through Jinja2,
applies CSS or SCSS, and writes the result with WeasyPrint, with helpers for the
things reports usually need: a figure as inline SVG, a DataFrame as a styled
table, a sidebar, a footer with page numbers.

It is the report layer under several tools in this repository, DnaChisel's
reports extra and genedom among them.}

# SCSS support, and undeclared upstream. preload_stylesheet defaults to
# is_scss="auto" and decides by file extension, so anyone handing it a .scss --
# which this project's own templates do -- hits a guarded ImportError without
# libsass. Recommends rather than Requires because plain CSS works without it.

# Upstream's suite, all of it. It writes real PDFs and reads them back with
# pypdf, compiles the .scss case through libsass, and renders one report with a
# matplotlib figure and a pandas table, so this covers the whole path rather
# than just the imports.

%changelog
* Sun Sep 27 2026 Morgan Hough <morgan.hough@gmail.com> - 0.3.9-1
- Initial package: pdf_reports 0.3.9. Net-new to Fedora.
- Needed by sequenticon and genedom, and it is DnaChisel's reports extra, so
  this unblocks more than the genedom chain.
- %%prep drops the backports.functools-lru-cache dependency: a Python 2
  backport, retired from Fedora, and upstream's own code prefers
  functools.lru_cache and can never reach the fallback here.
- Recommends python3-libsass, which upstream declares nowhere. Without it
  preload_stylesheet raises on any .scss input, and it decides by extension by
  default.
- Sourced from the GitHub tag; the sdist omits tests/data/.
