+# ModOrganizer2 - Python Proxy
+
+This repository contains the Python proxy plugin for ModOrganizer2.
+The proxy plugin allow developers to write Python plugins for ModOrganizer2.
+
+## Setup, build, tests
+
+This repository is part of MO2 main repositories and should usually be build using
+[`mob`](https://github.com/ModOrganizer2/mob).
+
+## Organization
+
+This repositories contains 5 sub-projects in `src`.
+The interface between Python and C++ is done using the
+[`pybind11`](https://github.com/pybind/pybind11) library.
+See the `README` in the subfolder (when there is one) for more details.
+
+- [`src/proxy`](src/proxy/) contains the actual proxy plugin.
+  This project is a simple interface between MO2 and the runner (see below).
+  The CMake code:
+  - generates the `plugin_python.dll` library,
+  - generates the translation file (under `src/`),
+  - installs necessary files for the plugin (Python DLL, Python libraries, etc),
+    including `mobase`.
+- [`src/runner`](src/runner/) contains the Python runner. This is the project that
+  instantiates a Python interpreter and load/unload Python plugins.
+- [`src/pybind11-qt`](src/pybind11-qt/) contains many utility stuff to interface
+  pybind11 with Qt and PyQt.
+- [`src/pybind11-utils`](src/pybind11-utils/) contains some utility stuff pybind11.
+  This project is header-only.
+- [`src/mobase`](src/mobase) contains the Python plugin interface.
+  - This projects generates the `mobase` Python library.
+
+Some (woefully incomplete) tests are available under `tests`, split in three
+sub-directories:
+
+- [`tests/mocks`](tests/mocks/) simply contains mocks of `uibase` interfaces to be used
+  in the two other test projects.
+- [`tests/python`](tests/python/) contains Python tests for `pytest`.
+  This project generates a bunch of Python test libraries that are then imported in
+  Python test files (`test_*.py`) and tested using `pytest`.
+  These tests mostly cover the pybind11 Qt and utility stuff, and some standalone
+  MO2 classes and functions (`IFileTree`, `GuessedString`, etc).
+- [`tests/runner`](tests/runner/) contains C++ tests, using GTest
+  Tests in this project instantiate a Python runner and then use it to check that
+  plugins implemented in Python can be used properly on the C++ side.
+
+## Building & Running tests
+
+Tests are not built by default with `mob`, so you will need to run `cmake` manually
+with the proper arguments.
+
+You need to define `PLUGIN_PYTHON_TESTS` with `-DPLUGIN_PYTHON_TESTS` when running
+the configure step of cmake.
+
+You can then build the tests
+
+```bash
+# replace vsbuild with your build folder
+cmake --build vsbuild --config RelWithDebInfo --target "python-tests" "runner-tests"
+```
+
+To run the tests, use `ctest`
+
+```bash
+# replace vsbuild with your build folder
+ctest.exe --test-dir vsbuild -C RelWithDebInfo
+```

+# mobase
+
+`mobase` is a ModOrganizer2 Python API.
+It provides access to the part of
+[`uibase`](https://github.com/ModOrganizer2/modorganizer-uibase) C++ API from
+Python through [`pybind11`](https://github.com/pybind/pybind11).
+
+## Organization
+
+**Important:** All (most) files should include `pybind11_all.h` (either directly
+or through another header) to get proper `type_caster` available.
+
+- `mobase.cpp` contains the `PYBIND11_MODULE` definition of `mobase` but is otherwise
+  the entrypoint for other functions.
+- `wrappers.h` contains the declaration of most functions implemented under
+  `wrappers/`.
+- The other files under `wrappers/` contains bindings and trampoline classes (see
+  below) for `uibase` classes.
+  - `basic_classes.cpp` contains the bindings for most classes that cannot be extended
+    in Python (`IOrganizer`, `IModInterface`, etc.)
+  - `game_features.cpp` contains the bindings and trampoline classes for game features.
+  - `pyfiletree.h` and `pyfiletree.cpp` contains bindings for the `IFileTree`-related
+    classes.
+  - `pyplugins.h` contains the trampoline classes for the `IPluginXXX` classes and
+    `pyplugins.cpp` the bindings.
+    - `pyplugins.h` is required since the trampoline classes are tagged with `Q_OBJECT`,
+      and MOC does not work if the classes are declared in a C++ file.
+    - `pyplugins.cpp` also contains the `extract_plugins` function in `mobase.private`
+      that is used to extract plugins from Python object in the runner.
+  - `widgets.cpp` contains the bindings for the widget classes.
+  - `wrappers.cpp` contains the trampoline and bindings for non-plugin classes that can
+    be extended through Python.
+
+## Updating mobase
+
+### Classes that cannot be extended through Python
+
+Updating or adding classes that cannot be extended through Python is quite easily.
+One simply needs to declare the appropriate `py::class_` or add new `.def()`.
+
+See below for things to remember when creating pybind11 bindings.
+
+### Free functions
+
+Similar to classes that cannot be extended through Python, see above.
+
+### Classes that can be extended through Python: Plugins
+
+To extend plugins, simply update the trampoline classes in `pyplugins.h` and the
+bindings in `pyplugins.cpp`.
+
+**Note:** For new plugins, simply look at the existing one.
+
+### Classes that can be extended through Python: Game Features
+
+To extend or expose game features:
+
+- Create (if there is not already one) a trampoline class for the feature in
+  `game_features.cpp`.
+  - Add implementation of missing functions if required.
+- Add the bindings in `add_game_feature_bindings` in `game_features.cpp`.
+- For new feature, add the feature type to `GameFeaturesHelper::GameFeatures` in
+  `game_features.cpp`.
+
+### Classes that can be extended through Python: Others
+
+Non-plugin classes should be added to the `wrappers.cpp` file and should be exposed
+with `std::shared_ptr<>` or `qobject_holder<>` holders.
+
+- If the classes extends `QObject`, use a `qobject_holder`.
+- Otherwise use a `std::shared_ptr<>` holder and add a `MO2_PYBIND11_SHARED_CPP_HOLDER`
+  declaration in `pybind11_all.h`.
+
+Trampoline can be defined directly in `wrappers.cpp`, and bindings in the appropriate
+function.
+See the existing classes for example.
+
+**Important:**
+You need to make sure that `uibase` manipulates such classes through
+`std::shared_ptr<>` (unless those inherit `QObject`).
+Using `std::unique_ptr<>` is not possible since `std::unique_ptr<>` cannot have custom
+runtime-specified deleters.
+
+## Things to remember
+
+Here are a few things to remember when creating bindings:
+
+- If a function has multiple overloads that can conflict in Python, the more complex
+  one must be defined first as pybind11 will try calling them in order.
+- If a C++ function expect a `QString`, `QFileInfo` or `QDir` that represents a file or
+  a directory, wrapping the function with `wrap_for_filepath` or `wrap_for_directory` is
+  a good idea. This allows Python to call the function with `pathlib.Path`.
+- Most of the C++ function taking a reference to modify in C++ cannot be directly
+  exposed in Python since Python cannot modify reference to simple type (e.g.
+  `QString&` or `int&`).
+  The best way to expose such function is to bind a lambda that returns a variant from
+  Python, e.g.
+
+```cpp
+// assume the C++ function is QString fn(QString& foo, QString const& bar, int& maz);
+
+m.def("function", [](QString& foo, QString const& bar, int& maz) {
+  // call the function
+  auto ret = function(foo, bar, maz);
+
+  // make a tuple containing the return value (if there is one), and the modified
+  // values passed by reference
+  return std::make_tuple(ret, foo, maz);
+});
+```
