# Sumi as an RPM, for Fedora COPR.
#
# Built and tested in the project's Fedora VM before it was ever
# uploaded -- see docs/distribution.md. The Homebrew release taught
# this the expensive way: a packaging path that has not been walked
# end to end is a packaging path that does not work.
#
# ## Why the sources are vendored
#
# COPR builds in mock, and mock has **no network**. `cargo build` would
# try to fetch every dependency from crates.io and fail. The source
# tarball therefore carries `vendor/` -- the output of `cargo vendor` --
# and `.cargo/config.toml` redirecting crates.io to it, so the build is
# offline by construction rather than by hoping.
#
# This is why Source0 is built by tools/rpm_source.sh and is not a
# plain `git archive`.
#
# ## Why not rust2rpm
#
# Fedora's own way is one RPM per crate, which is right for a library
# that other packages link. Sumi is a leaf application with a few
# hundred transitive dependencies; packaging each would be months of
# work for no one's benefit. Vendoring is what Fedora itself does for
# leaf Rust applications of this size.

# else. gtk4 >= 4.21 and libadwaita >= 1.9 are relm4's gnome_50
# feature's floor; see docs/building-linux.md.

%description
Sumi reads, annotates and edits PDF documents. Its engine is written
from scratch against ISO 32000-1 -- it uses no PDF library for
parsing, writing, rendering or signing -- and it carries the fourteen
standard fonts the specification requires a conforming reader to
provide.

%description -l de
Sumi liest, kommentiert und bearbeitet PDF-Dokumente. Der Motor ist von
Grund auf gegen ISO 32000-1 geschrieben und benutzt keine
PDF-Bibliothek, weder zum Lesen noch zum Schreiben, Zeichnen oder
Signieren. Die vierzehn Standardschriften, die die Norm von einem
konformen Betrachter verlangt, sind mitgeliefert.

# Offline, against the vendored tree the tarball carries. Release and
# not debug: the renderer rasterises pages, and an unoptimised build of
# that is slow enough to feel broken.

# The desktop entry is a template whose @BINARY@ is the installed path.

# carries an absolute path because there is no installation tree.

# Both of these have caught a real mistake in this project before: a
# desktop entry the shell silently ignores, and metadata GNOME Software
# refuses. They cost a second and they fail the build, which is the
# point -- a package that installs and then does not appear is the
# worst outcome.
