From 7ee008e150bc5bcf76082d726f719ee0fdfda982 Mon Sep 17 00:00:00 2001 From: SulfurNitride Date: Wed, 11 Feb 2026 02:37:39 -0600 Subject: Fluorine Manager: full Linux port of Mod Organizer 2 Complete native Linux port with FUSE-based virtual filesystem, Proton/umu-run integration, and Flatpak packaging. Key features: - FUSE VFS replacing Windows USVFS (in-process + standalone helper for Flatpak) - Proton/GE-Proton/umu-run launcher with env var forwarding - Flatpak support (sandbox-aware VFS, NXM handler, umu-run) - Wine prefix management UI - Case-insensitive path resolution for Linux filesystems - QSettings-safe INI handling (avoids Bethesda INI corruption) - Portable instance support with auto-generated launcher scripts Co-Authored-By: Claude Opus 4.6 --- libs/plugin_python/src/pybind11-utils/README.md | 50 +++++++++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 libs/plugin_python/src/pybind11-utils/README.md (limited to 'libs/plugin_python/src/pybind11-utils/README.md') diff --git a/libs/plugin_python/src/pybind11-utils/README.md b/libs/plugin_python/src/pybind11-utils/README.md new file mode 100644 index 0000000..46a9256 --- /dev/null +++ b/libs/plugin_python/src/pybind11-utils/README.md @@ -0,0 +1,50 @@ +# pybind11-utils + +This library contains some utility stuff for `pybind11` + +## smart_variant_wrapper.h + +Expose a function `mo2::python::wrap_arguments` and a template +`mo2::python::smart_variant` that can be used to expose more interesting types Python +than the C++ one, e.g., accept `os.PathLike` and `QFileInfo` when a simple `QString` is +expected. + +A toy example can be found in the test folder at +[`tests/python/test_argument_wrapper.cpp`](../../tests/python/test_argument_wrapper.cpp). + +More concrete examples can be found in +[`mobase/pybind11_all.h`](../mobase/pybind11_all.h) for `FileWrapper` and +`DirectoryWrapper`. + +## functional.h + +TODO: updated version of `` that should check the signature +a bit more when creating `std::function` (similar to previous implementation). + +## shared_cpp_owner.h + +Expose a macro `MO2_PYBIND11_SHARED_CPP_HOLDER` that can be used to declare that +`std::shared_ptr<...>` must hold-on their associate Python object. + +```cpp +// use the macro on the type to be exposed (with a trampoline class) +MO2_PYBIND11_SHARED_CPP_HOLDER(ISaveGame) + +// use std::shared_ptr<> as the holder for the class +py::class_>(...); +``` + +Using the `MO2_PYBIND11_SHARED_CPP_HOLDER` (must be present in all files manipulating +`ISaveGame` between C++ and Python) ensure that the Python instance remains alive +alongside the C++ one. + +The `MO2_PYBIND11_SHARED_CPP_HOLDER` declares a specialization of `type_caster<>` that +alters the `std::shared_ptr` by return a `std::shared_ptr<>` that owns the Python +object (via a `pybind11::object`) but does not release the C++ one - The C++ object is +owned by the Python one, so the relation is as follows: + +- The `std::shared_ptr` manipulated in C++ maintains the `pybind11::object` alive + through a custom deleter but DOES NOT release the C++ object when the reference count + reaches 0. +- The Python object holds a standard `std::shared_ptr` that will release the object + when the reference count reaches 0. -- cgit v1.3.1
