This will install the latest stubs on PyPi which usually corresponds to the latest release of MO2. You can install stubs for a specific version of MO2:

pip install mobase-stubs==2.3.2.*

If you want development stubs, you can install them this way:

# Clone this repository:
git clone https://github.com/ModOrganizer2/pystubs-generation.git

# Install the stubs:
cd pystubs-generation/stubs/setup
pip install .

Some words of warning:

The stubs are as correct as possible, but some errors are expected.
If you see a InterfaceNotImplemented class anywhere in the stubs, it means that a proper interface is currently not available.
Some classes are said (in the stubs) to inherit QWidget or QObject. This is true on the C++ side but NOT on the python side. The inheritance is only added to help with auto-completion since these classes also override __getattr__ to dispatch to the underlying QWidget or QObject. Some things might not work as expected with these class (e.g., isinstance(myObject, QObject) will return False), which is why a _object() and _widget() method is also provided.

Generating the stubs

The stubs are generated using python by parsing the mobase module. You need the version of python that matches your current MO2 installation: e.g., if you have a python38.dll in your MO2 installation path, then you need Python 3.8.

To generate the stubs, you can run:

# Change the output folder to whatever you want:
python main.py -c configs\config-2.4.yml ${MO2_INSTALL_PATH}

Where ${MO2_INSTALL_PATH} is the path to your MO2 installation (the one containing ModOrganizer.exe).

The stubs are generated under stubs/setup/mobase-stubs/__init__.pyi, you can change the output file by using the -o option The latest stubs are kept under stubs/setup/mobase-stubs/__init__.pyi, and when a new version is released, the stubs are backed-up under stubs/x.y.z/mobase.pyi.

A few options are available for main.py:

usage: Stubs generator for the MO2 python interface [-h] [-o OUTPUT] [-v] [-c CONFIG] INSTALL_DIR

positional arguments:
  INSTALL_DIR           installation directory of Mod Organizer 2

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        output file (default stubs/setup/mobase-stubs/__init__.pyi)
  -v, --verbose         verbose mode (all logs go to stderr)
  -c CONFIG, --config CONFIG
                        configuration file

The stubs generator will try hard to find a valid stubs for all classes and methods of mobase. A lot of information is available through the -v options. Without it, only conversions or fixes considered "strange" will be shown. For instance, here is the output with the current config-2.4.yml file:

WARNING: Replacing IOrganizer::FileInfo with FileInfo.
WARNING: Replacing IOrganizer::FileInfo with FileInfo.
WARNING: Replacing IPluginInstaller::EInstallResult with InstallResult.
WARNING: Replacing IPluginInstaller::EInstallResult with InstallResult.

As you can see, only a few types were manually fixed (specified in config-2.4.yml).

Configuration file

The configuration file contains information for the stubs that cannot be deduced by main (or are too complex to deduce), and the documentation for everything.

Uploading the stubs to pypi

The upload of the stubs to https://pypi.org/project/mobase-stubs/ should be done automatically when a new Github release is made.

Extras — Starts a python interpreter with `mobase`

It is possible to start a (i)python interpret with mobase imported by running:

python -im generator.loader ${MO2_INSTALL_PATH}

This has no real usage except for MO2 developers since most classes from the mobase module cannot be instantiated.
