Credits

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.

Installation

Stable release

To install berserk, run this command in your terminal:

$ pip install berserk

This is the preferred method to install berserk, as it will always install the most recent stable release.

If you don’t have pip installed, this Python installation guide can guide you through the process.

From sources

The sources for berserk can be downloaded from the Github repo.

You can either clone the public repository:

$ git clone git://github.com/rhgrant10/berserk

Or download the tarball:

$ curl  -OL https://github.com/rhgrant10/berserk/tarball/master

Once you have a copy of the source, you can install it with:

$ python setup.py install

Usage

Use berserk by creating an API client:

>>> import berserk
>>> client = berserk.Client()

Authenticating

By default the client does not perform any authentication. However many of the endpoints are not open. To use a form of authentication, just pass the appropriate requests.Session-like object:

  • using an API token: berserk.TokenSession
  • using oauth: requests_oauthlib.Oauth2Session

Note

Some endpoints require specific Oauth2 permissions.

Using an API token

If you have a personal API token, you can simply use the TokenSession provided. For example, assuming you have written your token to './lichess.token':

>>> with open('./lichess.token') as f:
...     token = f.read()
...
>>> session = berserk.TokenSession(token)
>>> client = berserk.Client(session)

Using Oauth2

Some of the endpoints require OAuth2 authentication. Although outside the scope of this documentation, you can use requests_oauthlib.Oauth2Session for this.

>>> from requests_oauthlib import OAuth2Session
>>> session = OAuth2Session(...)
>>> client = berserk.Client(session)

Accounts

Information and Preferences

>>> client.account.get()
{'blocking': False,
 'count': {...},
 'createdAt': datetime.datetime(2018, 5, 16, 8, 9, 18, 187000),

>>> client.account.get_email()
'rhgrant10@gmail.com'

>>> client.account.get_preferences()
{'animation': 2,
 'autoQueen': 1,
 ...
 'transp': False,
 'zen': 0}}

Kid Mode

Using Oauth2, you can set the kid mode.

>>> client.account.set_kid_mode(True)  # enable
True
>>> client.account.set_kid_mode(False)  # disable
True

Note that the set_kid_mode method returns an indicator of success and not the current or previous status.

>>> def show_kid_mode():
...     is_enabled = client.account.get_kid_mode()
...     print('enabled' if is_enabled else 'disabled')
...
>>> show_kid_mode()
disabled

>>> # try to enable, but the request fails
>>> client.account.set_kid_mode(True)
False
>>> show_kid_mode()
disabled

>>> # try again, this time it succeeds
>>> client.account.set_kid_mode(True)
True
>>> show_kid_mode()
enabled

Bot Account Upgrade

If this is a new account that has not yet played a game, and if you have the required OAuth2 permission, you can upgrade the account to a bot account:

>>> client.account.upgrade_to_bot()

Read more below about how to use bot functionality.

Exporting Games

By Player

Finished games can be exported and current games can be listed. Let’s take a look at the most recent 300 games played by “LeelaChess” on Dec. 8th, 2018:

>>> start = berserk.utils.to_millis(datetime(2018, 12, 8))
>>> end = berserk.utils.to_millis(datetime(2018, 12, 9))
>>> client.games.export_by_player('LeelaChess', since=start, until=end,
                                  max=300))
<generator object Games.export_by_player at 0x10c24b048>
>>> games = list(_)
>>> games[0]['createdAt']
datetime.datetime(2018, 12, 9, 22, 54, 24, 195000, tzinfo=datetime.timezone.utc)
>>> games[-1]['createdAt']
datetime.datetime(2018, 12, 8, 9, 11, 42, 229000, tzinfo=datetime.timezone.utc)

Wow, they play a lot of chess :)

By ID

You can export games too using their IDs. Let’s export the last game LeelaChess played that day:

>>> game_id = games[0]['id']
>>> client.games.export(game_id)
{'analysis': [...],
 'clock': {'increment': 8, 'initial': 300, 'totalTime': 620},
 'createdAt': datetime.datetime(2018, 12, 9, 22, 54, 24, 195000, tzinfo=datetime.timezone.utc),
 'id': 'WatQhhbJ',
 'lastMoveAt': datetime.datetime(2018, 12, 9, 23, 5, 59, 396000, tzinfo=datetime.timezone.utc),
 'moves': ...
 'opening': {'eco': 'D38',
  'name': "Queen's Gambit Declined: Ragozin Defense",
  'ply': 8},
 'perf': 'rapid',
 'players': {'black': {'analysis': {'acpl': 44,
    'blunder': 1,
    'inaccuracy': 4,
    'mistake': 2},
   'rating': 1333,
   'ratingDiff': 0,
   'user': {'id': 'fsoto', 'name': 'fsoto'}},
  'white': {'analysis': {'acpl': 11,
    'blunder': 0,
    'inaccuracy': 2,
    'mistake': 0},
   'provisional': True,
   'rating': 2490,
   'ratingDiff': 0,
   'user': {'id': 'leelachess', 'name': 'LeelaChess', 'title': 'BOT'}}},
 'rated': True,
 'speed': 'rapid',
 'status': 'mate',
 'variant': 'standard',
 'winner': 'white'}

PGN vs JSON

Of course sometimes PGN format is desirable. Just pass as_pgn=True to any of the export methods:

>>> pgn = client.games.export(game_id, as_pgn=True)
>>> print(pgn)
[Event "Rated Rapid game"]
[Site "https://lichess.org/WatQhhbJ"]
[Date "2018.12.09"]
[Round "-"]
[White "LeelaChess"]
[Black "fsoto"]
[Result "1-0"]
[UTCDate "2018.12.09"]
[UTCTime "22:54:24"]
[WhiteElo "2490"]
[BlackElo "1333"]
[WhiteRatingDiff "+0"]
[BlackRatingDiff "+0"]
[WhiteTitle "BOT"]
[Variant "Standard"]
[TimeControl "300+8"]
[ECO "D38"]
[Opening "Queen's Gambit Declined: Ragozin Defense"]
[Termination "Normal"]

1. d4 { [%eval 0.08] [%clk 0:05:00] } 1... d5 ...

TV Channels

>>> channels = client.games.get_tv_channels()
>>> list(channels)
['Bot',
 'Blitz',
 'Racing Kings',
 'UltraBullet',
 'Bullet',
 'Classical',
 'Three-check',
 'Antichess',
 'Computer',
 'Horde',
 'Rapid',
 'Atomic',
 'Crazyhouse',
 'Chess960',
 'King of the Hill',
 'Top Rated']
>>> channels['King of the Hill']
{'gameId': 'YPL6tP2K',
 'rating': 1554,
 'user': {'id': 'linischoki', 'name': 'linischoki'}}

Working with tournaments

You have to specify the clock time, increment, and minutes, but creating a new tournament is easy:

>>> client.tournaments.create(clock_time=10, clock_increment=3, minutes=180)
{'berserkable': True,
 'clock': {'increment': 3, 'limit': 600},
 'createdBy': 'rhgrant10',
 'duels': [],
 'fullName': "O'Kelly Arena",
 'greatPlayer': {'name': "O'Kelly",
  'url': "https://wikipedia.org/wiki/Alb%C3%A9ric_O'Kelly_de_Galway"},
 'id': '3uwyXjiC',
 'minutes': 180,
 'nbPlayers': 0,
 'perf': {'icon': '#', 'name': 'Rapid'},
 'quote': {'author': 'Bent Larsen',
  'text': 'I often play a move I know how to refute.'},
 'secondsToStart': 300,
 'standing': {'page': 1, 'players': []},
 'startsAt': '2018-12-10T00:32:12.116Z',
 'system': 'arena',
 'variant': 'standard',
 'verdicts': {'accepted': True, 'list': []}}

You can specify the starting position for new tournaments using one of the provided enum value in berserk.enums.Position:

>>> client.tournaments.create(clock_time=10, clock_increment=3, minutes=180,
                              position=berserk.enums.Position.KINGS_PAWN)

Additionally you can see tournaments that have recently finished, are in progress, and are about to start:

>>> tournaments = client.tournaments.get()
>>> list(tournaments)
['created', 'started', 'finished']
>>> len(tournaments['created'])
19
>>> tournaments['created'][0]
{'clock': {'increment': 0, 'limit': 300},
 'createdBy': 'bashkimneziri',
 'finishesAt': datetime.datetime(2018, 12, 24, 0, 21, 2, 179000, tzinfo=datetime.timezone.utc),
 'fullName': 'GM Arena',
 'id': 'COnVgmKH',
 'minutes': 45,
 'nbPlayers': 1,
 'perf': {'icon': ')', 'key': 'blitz', 'name': 'Blitz', 'position': 1},
 'rated': True,
 'secondsToStart': 160,
 'startsAt': datetime.datetime(2018, 12, 23, 23, 36, 2, 179000, tzinfo=datetime.timezone.utc),
 'status': 10,
 'system': 'arena',
 'variant': {'key': 'standard', 'name': 'Standard', 'short': 'Std'},
 'winner': None}

Being a bot

Warning

These commands only work using bot accounts. Make sure you have converted the account with which you authenticate into a bot account first. See above for details.

Bots stream game information and react by calling various endpoints. There are two streams of information:

  1. incoming events
  2. state of a particular game

In general, a bot will listen to the stream of incoming events, determine which challenges to accept, and once accepted, listen to the stream of game states and respond with the best moves in an attempt to win as many games as possible. You can create a bot that looses intentionally if that makes you happy, but regardless you will need to listen to both streams of information.

The typical pattern is to have one main thread that listens to the event stream and spawns new threads when accepting challenges. Each challenge thread then listens to the stream of state for that particular game and plays it to completion.

Responding to challenges

Here the goal is to respond to challenges and spawn workers to play those accepted. Here’s a bit of sample code that hits the highlights:

>>> is_polite = True
>>> for event in client.bots.stream_incoming_events():
...     if event['type'] == 'challenge':
...         if should_accept(event):
...             client.bots.accept_challenge(event['id'])
...         elif is_polite:
...             client.bots.decline_challenge(event['id'])
...     elif event['type'] == 'gameStart':
...         game = Game(event['id'])
...         game.start()
...

Playing a game

Having accepted a challenge and recieved the gameStart event for it, the main job here is to listen and react to the stream of the game state:

>>> class Game(threading.Thread):
...     def __init__(self, client, game_id, **kwargs):
...         super().__init__(**kwargs)
...         self.game_id = game_id
...         self.client = client
...         self.stream = client.bots.stream_game_state(game_id)
...         self.current_state = next(self.stream)
...
...     def run(self):
...         for event in self.stream:
...             if event['type'] == 'gameState':
...                 self.handle_state_change(event)
...             elif event['type'] == 'chatLine':
...                 self.handle_chat_line(event)
...
...     def handle_state_change(self, game_state):
...         pass
...
...     def handle_chat_line(self, chat_line):
...         pass
...

Obviously the code above is just to communicate the gist of what is required. But once you have your framework for reacting to changes in game state, there are a variety of actions you can take:

>>> client.bots.make_move(game_id, 'e2e4')
True
>>> client.bots.abort_game(game_id)
True
>>> client.bots.resign_game(game_id)
True
>>> client.bots.post_message(game_id, 'Prepare to loose')
True

Developer Interface

Clients

You can contribute in many ways:

Types of Contributions

Report Bugs

Report bugs at https://github.com/rhgrant10/berserk/issues.

If you are reporting a bug, please include:

  • Your operating system name and version.
  • Any details about your local setup that might be helpful in troubleshooting.
  • Detailed steps to reproduce the bug.

Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” and “help wanted” is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with “enhancement” and “help wanted” is open to whoever wants to implement it.

Write Documentation

berserk could always use more documentation, whether as part of the official berserk docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/rhgrant10/berserk/issues.

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up berserk for local development.

  1. Fork the berserk repo on GitHub.

  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/berserk.git

  3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:

    $ mkvirtualenv berserk
$ cd berserk/
$ python setup.py develop

  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:

    $ flake8 berserk tests
$ python setup.py test or py.test
$ tox

    To get flake8 and tox, just pip install them into your virtualenv.

  6. Commit your changes and push your branch to GitHub:

    $ git add .
$ git commit -m "Your detailed description of your changes."
$ git push origin name-of-your-bugfix-or-feature

  7. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.
  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.
  3. The pull request should work for Python 2.7, 3.4, 3.5 and 3.6, and for PyPy. Check https://travis-ci.org/rhgrant10/berserk/pull_requests and make sure that the tests pass for all supported Python versions.

Tips

To run a subset of tests:

$ py.test tests.test_berserk

Deploying

A reminder for the maintainers on how to deploy. Make sure all your changes are committed (including an entry in HISTORY.rst). Then run:

$ bumpversion patch # possible: major / minor / patch
$ git push
$ git push --tags

Travis will then deploy to PyPI if tests pass.
