Name

Configuring the environment for interpreting LensKit scripts.

Description

Several subcommands of lenskit(1) interpret scripts, either to configure recommenders or to run evaluations. These subcommands support some common options for configuring the Java environment in which these scripts are interpreted; this page documents those options.

Script Environment Options

-C URL, –classpath URL

Add URL (which can be a path to a local directory or JAR file) to the classpath for loading the configuration scripts. This URL can contain additional components for the recommenders. This option can be specified multiple times to add multiple locations to the classpath.

-D PROP=VALUE, –define PROP=VALUE

Define the property PROP to equal VALUE. These properties will be available in the properties object in the interpreted script. To set Java system properties, use the JAVA_OPTS environment variable (see lenskit(1)).
