# EVIDENCE BUILD -- Fedora's rawhide python-cascadio.spec (0.0.17, UNCHANGED version) plus TWO edits in
# %prep for OpenCASCADE 8 (C++17, and one explicit include); see the comment at each.
#
# NOT cascadio 0.1.1: tags from 0.0.18rc0 onward (0.1.1 is current) call a PATCHED OpenCASCADE API --
# RWGltf_CafWriter::JsonPostProcessCallback/BinaryAppendCallback/SetFaceDataCallback, plus a "memfd
# patch" -- that stock OpenCASCADE does not have, so they cannot build against a system copy at all,
# on 7.9 or 8 (build 11080899: 21 errors in src/convert.hpp). 0.0.17 has 0 such references.

%global common_description %{expand:
A Python library which uses OpenCASCADE to convert STEP files to a GLB file
which can quickly be loaded by trimesh and other libraries.

This is not intended to be a full binding of OpenCASCADE like OCP or PythonOCC.
Rather it is intended to be an easy minimal way to load boundary representation
files into a triangulated scene in Python. There are a few options for loading
STEP geometry in the open-source ecosystem: GMSH, FreeCAD, etc. However nearly
all of them use OpenCASCADE under the hood as it is pretty much the only
open-source BREP kernel.}

# EVIDENCE-BUILD CHANGE (the only one): raise the C++ standard. OpenCASCADE 8 needs C++17 (its headers
# use std::shared_mutex); cascadio 0.0.17 hardcodes `-std=c++11` at CMakeLists.txt:26, which gave 509
# errors inside OCCT's headers (mhough/opencascade8-rawhide build 11080660). The assertion makes the
# edit fail loudly if the line ever changes, instead of silently doing nothing.

sed -i 's/-std=c++11/-std=c++17/' CMakeLists.txt
grep -q -- '-std=c++17' CMakeLists.txt

# EVIDENCE-BUILD CHANGE 2 of 2: OCCT 8 no longer pulls TColStd_IndexedDataMapOfStringString in through the
# headers cascadio includes, so src/convert.hpp:83 and :151 fail with `was not declared in this scope`
# (build 11081289). The alias header ships in both 7.9.3 and 8.0.1 (in 8.0 it is a deprecated typedef for
# NCollection_IndexedDataMap<TCollection_AsciiString, TCollection_AsciiString>), so including it explicitly
# is portable across both versions.
# src/convert.hpp has CRLF line endings, so every anchor tolerates a trailing carriage return -- a plain
# `...hxx>$` anchor matches nothing under GNU grep/sed and would abort %prep (found by running these
# lines against the real file with GNU tools; the first draft only passed under ugrep).
