For non-developers who want to try this development code, the easiest way is
to use a binary package - please see:

https://anki.tenderapp.com/discussions/beta-testing

You are welcome to run Anki from source instead, but it is expected that you
can sort out all dependencies and issues by yourself - we are not able to
provide support for problems you encounter when running from source.

To start, make sure you have the following installed:

 - Python 3.7+
 - portaudio
 - mpv
 - lame
 - npm
 - your platform's C compiler, eg gcc, Xcode or Visual Studio 2017.
 - GNU make
 - protoc v3 (https://github.com/protocolbuffers/protobuf/releases)
 - rustup (https://rustup.rs/)
 - gettext
 - rename
 - rsync

The build scripts assume a UNIX-like environment, so on Windows you will
need to use WSL or Cygwin to use them.

Once you've installed the above components, execute ./run in this repo,
which will build the subcomponents, and start Anki. Any arguments included
on the command line will be passed on to Anki.

Before contributing code, please read README.contributing.

of http://ankisrs.net/docs/manual.html#_contributing

Subcomponents
--------------

- pylib contains a Python module (anki) with most of the non-GUI code.
- qt contains the Qt GUI implementation (aqt).
- rspy contains a Python module (ankirspy) for accessing the Rust code.
- rslib contains the parts of the code implemented in Rust. This
  is only a tiny subsection at the moment.
- proto contains the interface used to communicate between different
  languages.
- tslib and react are just an experiment at the moment.

Makefile
--------------

Use 'make check' to run unit tests, type checking and linting on all of the
subcomponents.

Use 'make fix' to fix any formatting issues that were found with 'make check'.

Use 'make build' to output Python wheels of the subcomponents into the dist/
folder.

Use 'make clean' to remove some generated files.

PyQt
-----

The build scripts will use PyQt/Qt from PyPI by default. If you wish to use a
system install, you will need to set up the pyenv folder yourself, making sure
you have PyQt5, the WebEngine module and development tools (eg pyqt5-dev-tools)
installed as well. You'll need to create the venv with --system-site-packages.

Mac users
----------

You can use homebrew to install some dependencies:

$ brew install python mpv lame portaudio protobuf npm rustup-init gettext rename

$ brew link gettext --force
