%description
MRIcron is a cross-platform NIfTI format image viewer. It allows viewing
multiple layers of images, generating volume renderings, and drawing volumes
of interest (VOI). This is the native compiled version built with Lazarus
and Qt5.

%prep
%autosetup -n MRIcron-%{git_commit}

# 1. Fix Line Endings (CRLF -> LF)
find . -type f \( -name "*.ini" -o -name "*.lut" -o -name "*.txt" -o -name "*.md" \) -exec dos2unix {} \;

# 2. Fix Permissions (remove executable bit from non-binaries)
find . -type f -exec chmod 644 {} \;

%build
# Re-enable execute on the project file so lazbuild can read it
chmod 644 mricron.lpi
lazbuild -B --ws=qt5 mricron.lpi

%install
rm -rf %{buildroot}

# 1. Prepare directories
mkdir -p %{buildroot}%{_libexecdir}/%{name}
mkdir -p %{buildroot}%{_bindir}
mkdir -p %{buildroot}%{_datadir}/applications
mkdir -p %{buildroot}%{_datadir}/icons/hicolor/128x128/apps

# 2. Install Binary
install -m 755 MRIcron %{buildroot}%{_libexecdir}/%{name}/%{name}

# 3. Install Resources
cp -r render %{buildroot}%{_libexecdir}/%{name}/
cp -r Resources/templates %{buildroot}%{_libexecdir}/%{name}/
cp -r Resources/lut %{buildroot}%{_libexecdir}/%{name}/
cp *.txt %{buildroot}%{_libexecdir}/%{name}/

# 4. Create Wrapper Script
cat > %{buildroot}%{_bindir}/%{name} <<EOF
#!/bin/bash
exec %{_libexecdir}/%{name}/%{name} "\$@"
EOF
chmod 755 %{buildroot}%{_bindir}/%{name}

# 5. Symlink dcm2niix (Relative path fix)
ln -s ../../bin/dcm2niix %{buildroot}%{_libexecdir}/%{name}/dcm2niix

# 6. Install Desktop Entry
# Install UPSTREAM's desktop entry (Debian/mricron.desktop) rather than a
# hand-written copy. Upstream's carries GenericName and German and Russian
# translations and already had Exec=... %F.
#
# It does NOT validate as shipped -- `desktop-file-validate` exits 1 with two
# errors -- so the fixes below are what make it installable at all, and are
# reported upstream in docs/upstream/mricrogl-mricron-desktop-entries.md:
#   * Version=<ver> is a literal placeholder. Version is the desktop-entry
#     SPEC version, so it is 1.0 and needs no substitution.
#   * Categories contains QT5, which is not a registered value (Qt is), and
#     names four main categories.
#   * Comment=Edit Exec and Icon paths for your system is an instruction to
#     packagers sitting in the field a file manager shows to the USER.
#   * no MimeType, which makes any default-application setting inert.

# 7. Install Icon
install -m 644 mricron.png %{buildroot}%{_datadir}/icons/hicolor/128x128/apps/%{name}.png

# AppStream metadata. A .desktop file makes an application launchable; a
# metainfo file makes it DISCOVERABLE -- GNOME Software and KDE Discover list
# only applications that ship one. Validation runs here rather than in
# %check so a malformed file fails the build instead of shipping and being
# silently ignored, which is how Ankur Sinha does it in Fedora's
# python-fsleyes.

%changelog
* Sun Oct 04 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-6
- BuildRequires: desktop-file-utils. -5 installs upstream's desktop entry with
  desktop-file-install and failed on fedora-44-x86_64 (build 11064829) with
  "desktop-file-install: command not found" -- mricron was the only one of the
  five desktop/AppStream packages that did not declare it. The other chroots
  still serve -4, so this is the first -5 that can reach them.

* Fri Oct 02 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-5
- Install upstream's own desktop entry (Debian/mricron.desktop) instead of
  the one this spec wrote by hand. Upstream's has GenericName and German and
  Russian translations.
- It does not validate as shipped: Version=<ver> is a literal placeholder and
  QT5 is not a registered category, so desktop-file-validate exits 1 and
  desktop-file-install would refuse it. Fixed here with --set-key, and
  reported upstream. Also replaces Comment=Edit Exec and Icon paths for your
  system, which is a note to packagers occupying the description a file
  manager shows the user.
- Adds Keywords and MimeType, without which a default application for NIfTI
  is silently ignored by the desktop.

* Tue Sep 29 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-4
- Ship AppStream metadata (mricron.metainfo.xml). A desktop entry makes an application
  launchable; a metainfo file makes it DISCOVERABLE, because GNOME Software
  and KDE Discover list only applications that ship one. Twenty of the
  twenty-six applications in this repo had a desktop entry and no metainfo,
  so they were invisible in the software centre even once installed.
  Validated at build time with appstream-util validate-relax --nonet, in
  %install rather than %check, so a malformed file fails the build.
- Added Requires: hicolor-icon-theme, which the icons need.

* Tue Sep 29 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-3
- Exec takes %%F so the entry can open the file it is given, and MimeType
  is declared for NIfTI and DICOM; without the declaration any default
  pointing here is silently ignored by the desktop.
- Deliberately NOT claiming *.hdr/*.img for Analyze: f3d owns *.hdr as
  Radiance HDR and *.img collides with raw disk images.

* Sun Jan 04 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-2
- Fix permissions on templates and LUTs
- Fix line endings (dos2unix) for docs and config files
- Use relative symlink for dcm2niix to satisfy rpmlint

* Sun Jan 04 2026 Morgan Hough <morgan.hough@gmail.com> - 1.2.20250101-1
- Initial RPM release built with Lazarus and Qt5
