User interface and public API for probing Syzygy endgame tablebases.

Dependencies:

pip install flask
pip install python-chess
pip install tornado # Required for dealing with many
                    # open file descriptors
                    # when serving six-men tablebases.
pip install htmlmin # Recommended.

npm install -g grunt-cli
npm install

Create combined JavaScript and CSS files using Grunt:

grunt

Start the server on port 5000:

python server.py

Only the small four-men tablebases are in this Git repository. Optionally generate or download five-men and six-men tablebases and place them in the corresponding directories.

Optionally build and install libgtb and download Gaviota tablebase files. Put them into the gaviota directory.

See https://syzygy-tables.info/apidoc for information about the JSON API.

Have a look at server.py for server side code. The client side code is in static/js/client.js.
