The easiest way to start up Kawa is to run the ‘kawa’ program.
This finds your java interpreter, and sets up ‘CLASSPATH’ correctly.
If you have installed Kawa such $PREFIX/bin is in your $PATH,
just do:
kawa
However, ‘kawa’ only works if you have a Unix-like environment.
On some platforms, ‘kawa’ is a program that uses the GNU
‘readline’ library to provide input line editing.
To run Kawa manually, you must start a Java interpreter.
How you do this depends on the Java interpreter.
For Sun's JDK s and some other implementations, you must have the
Java interpret (usually named java) in your PATH.
You must also make sure that the kawa/repl.class file,
the rest of the Kawa packages, and the standard Java
packages can be found by searching CLASSPATH.
See Getting and running Java.
Then you do:
java kawa.repl
In either case, you will then get the ‘#|kawa:1|#’ prompt,
which means you are
in the Kawa read-eval-print-loop. If you type a Scheme
expression, Kawa will evaluate it. Kawa will then print the
result (if there is a non-"void" result).
