To run Scala from the command-line, simply download the binaries and unpack the archive.
Start the Scala interpreter (aka the “REPL”) by launching scala from where it was unarchived. Start the Scala compiler by launching scalac from where it was unarchived.
Path and Environment
For quick access, add scala and scalac to your path. For example:
| Environment | Variable | Value (example) |
|---|---|---|
| Unix | $SCALA_HOME |
/usr/local/share/scala |
$PATH |
$PATH:$SCALA_HOME/bin |
|
| Windows | %SCALA_HOME% |
c:\Progra~1\Scala |
%PATH% |
%PATH%;%SCALA_HOME%\bin |
