Introduction to Scala

Quick Start

This guide will help you get up and running with GeoScript Scala.

Java Virtual Machine

GeoScript Scala requires the Java Virtual Machine in order to operate. Most systems have Java preinstalled; you can verify this with the command:

$ java -version
java version "1.5.0_20"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_20-b02-315)
Java HotSpot(TM) Client VM (build 1.5.0_20-141, mixed mode, sharing)

If your Java version is 1.5 or greater, you are ready to install GeoScript Scala. Otherwise, we recommend installing Sun’s JVM, available from the Sun website.

Installing GeoScript

You can download an archive of the latest GeoScript Scala release at the `GitHub download page<>`_. Unpack the archive to your filesystem:

$ tar xvzf geoscript-0.1.tar.gz

After unpacking, you can run the GeoScript interpreter by specifying the path:

$ geoscript-0.1/bin/geoscript-scala
Welcome to Scala version (HotSpot(TM) Client VM, Java 1.5.0_20-141)
Type in expressions to have them evaluated.
Type :help for more information.


Adding to the PATH

In order to avoid needing to provide the path every time you want to use GeoScript, you can add GeoScript to your shell’s PATH variable. On Mac OSX, Linux, and other Unixy systems, you can do this:

$ echo 'export PATH=/path/to/geoscript/:$PATH' >> ~/.profile
$ . ~/.profile # apply changes, otherwise they won't apply until next login

On Windows, you can do this by editing your PATH environment variable through the Properties dialog for My Computer.
