Running from source
--------------------

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.

Anki requires:

 - Python 3.6+
 - Qt 5.9.x/5.11.x/5.12.x and a PyQT that supports it
 - mpv
 - lame

It also requires a number of Python packages, which you can grab via pip:

$ pip3 install -r requirements.txt

If you're on a Linux distribution that packages a compatible Qt then you can
use the distro's packages. Make sure you install the development tools (eg
pyqt5-dev-tools) as well.

If you're on another platform or your distro has the wrong Qt version, you
can install PyQt with pip:

$ pip3 install PyQt5 PyQtWebEngine

To use the development version:

$ git clone https://github.com/dae/anki.git
$ cd anki
$ ./tools/build_ui.sh

If you get any errors, you will not be able to proceed, so please return to
the top and check the requirements again.

ALL USERS: Make sure you rebuild the UI every time you git pull, otherwise you
will get errors down the road.

The translations are stored in a bazaar repo for integration with Launchpad's
translation services. If you want to use a language other than English:

$ cd ..
$ mv anki dtop # i18n code expects anki folder to be called dtop
$ bzr branch lp:anki i18n
$ cd i18n
$ ./update-mos.sh
$ cd ../dtop

And now you're ready to run Anki:
$ ./runanki

If you get any errors, please make sure you don't have an older version of
Anki installed in a system location.

To run the unit tests, you will need to install nose and mock from your
distro, or with pip:

$ pip3 install nose mock

Before contributing code, please read README.contributing.

Windows & Mac users
---------------------

The following was contributed by users in the past and will need updating
for the latest version. It is left here in case it is any help:

Windows:

I have not tested the build scripts on Windows, so you'll need to solve any
problems you encounter on your own. The easiest way is to use a source
tarball instead of git, as that way you don't need to build the UI yourself.

If you do want to use git, two alternatives have been contributed by users. As
these are not official solutions, I'm afraid we can not provide you with any
support for these.

A powershell script:

https://gist.github.com/vermiceli/108fec65759d19645ee3

Or a way with git bash and perl:

    1) Install "git bash".
    2) In the tools directory, modify build_ui.sh. Locate the line that reads
    "pyuic5 --from-imports $i -o $py.tmp" and alter it to be of the following form:
    "<python-path-string>" "<pyuic-path-string>" $i -o $py
    These two paths must point to your python executable, and to pyuic.py, on your
    system. Typical paths would be:
    <python-path> = C:\\Python27\\python.exe
    <pyuic-path-string> = C:\\Python27\\Lib\\site-packages\\PyQt4\\uic\\pyuic.py

Mac:

These instructions may be incomplete as prerequisites may have already been
installed. Most likely you will need to have installed xcode
(https://developer.apple.com/xcode/)

Install homebrew (http://brew.sh/) and then install Anki prerequisites:

$ brew install python mplayer lame portaudio

Now you can follow the development commands at the start of this document.
