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 that $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 Virtual Machine.
How you do this depends on the Java implementation.
For Oracle’s JDK, and some other implementations, you must have the
Java evaluator (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 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).
