Application which can connect to Lichess using a Lichess BOT account, and start accepting challenges (non-rated, standard + Chess 960).
The application only plays random moves, so it is definitely possible to win against it.
When the application is running, your Lichess BOT account will show up as online at https://lichess.org/player/bots.
Example of a Lichess BOT account which uses this application: https://lichess.org/@/charibot
The latest version of the application is available for download for Windows, Mac and Linux at https://github.com/tors42/charibot/releases/latest
Unzipping the downloaded archive will create a directory charibot-<version>
and the application can be launched from a command-line terminal with
charibot-<version>/bin/bot
You will need a Lichess (BOT) account. If you don't already have a Lichess account, you can create an account at https://lichess.org/signup
If you use a new account which is not yet a BOT account, the application will ask you if you want to convert the account to a BOT account.
$ bin/bot
or
$ bin/bot.exe
When running the application for the first time, you will be asked to authorize the application to access your BOT account, which will create and store a token which the application can use to send moves to Lichess. The token will be reused when running the application again, so only need to authorize once.
Note, it is possible to revoke the token at any time via https://lichess.org/account/security, and if running the application again you will once again be asked to authorize the application.
Note, if you already have a Lichess BOT account and an existing token with bot:play scope,
you can run the application with that token set in an environment variable BOT_TOKEN:
$ export BOT_TOKEN=lip_...
$ bin/bot
or
$ set BOT_TOKEN=lip_...
$ bin/bot.exe
This is an application written in Java and is managed as a
Maven project which has been configured to package
the application using jlink.
This means that Java will not be needed on the computer that runs the application.
The workflow which builds the application can be seen in build.yml.
$ mvn clean verify
The application will be packaged in target/charibot-0.0.1-SNAPSHOT-<os>-<arch>.zip
(and unpackaged in target/maven-jlink/classifiers/<os>-<arch>/, so can be run with
target/maven-jlink/classifiers/<os>-<arch>/bin/bot)
Note, it is also possible to run the application from source without building it with Maven. This needs the above JDK, downloading of dependency chariot-0.1.8.jar and providing command-line flags:
$ java --enable-preview -p chariot-0.1.8.jar --add-modules chariot src/main/java/bot/Bot.java
