FESI (pronounced like fuzzy)  is a full implementation of the first version of the EcmaScript language (defined in the standard ECMA 262 available at http://www.ecma-international.org (edition of june 97).  EcmaScript is largely equivalent to the JavaScript language version 1.1 or to the core part of JScript, but without the navigator specific extensions.

Capabilities:


The documentation of FESI is included here. It is part of the kit too.

FESI consists of a set of java packages , allowing to use EcmaScript as a macro language for Java applications, and of an interactive interpreter (usable from the command line to test EcmaScript programs). The integration with Java is very strong, making FESI a useful tool to test Java libraries.

There is a simple editor included with the Swing version of the interpreter. You can execute scripts interactively or from the editor windows.
