Smile

Shell

Smile comes with interactive shells for Java, Scala and Kotlin. Download pre-packaged Smile from the releases page. In the home directory of Smile, type

    ./bin/smile

to enter the Scala shell. You can run any valid Scala expressions in the shell. In the simplest case, you can use it as a calculator. Besides, all high-level Smile operators are predefined in the shell. By default, the shell uses up to 75% memory. If you need more memory to handle large data, use the option -J-Xmx or -XX:MaxRAMPercentage. For example,

    ./bin/smile -J-Xmx30G

You can also modify the configuration file ./conf/smile.ini for the memory and other JVM settings.

To use Java’s JShell, type

    ./bin/jshell.sh

which has Smile’s jars in the classpath. Similarly, run

    ./bin/kotlin.sh

to enter Kotlin REPL.
