Language::Frink::Eval 0.02

Language::Frink::Eval is a Perl module that acts as a simple wrapper around the Frink interpreter written by Alan Eliasen. As such, it requires a local copy of the Java interpreter and the frink.jar file. For more information on Frink, please see http://futureboy.homeip.net/frinkdocs/.

This module works by starting a JVM as a child process, and sending Frink expressions to it via a pipe, and retrieving the results the same way. Also, this module has the ability to function in a restricted mode it attempts to filter "dangerous" expressions, such as functions that read files from local disk, the network, and also commands that may persistantly change the interpreter state.

The list of "dangerous" functions and expressions was derived by reading the Frink documentation, and probably is not complete. If you find commands that get through the filter that should, please report them.

The following functions are not allowed in restricted mode:

lines[]
read[]
eval[]
input[]
select[]
callJava[]
newJava[]
staticJava[]

The following language constructs are not allowed in restricted mode:

Regexes
Function Declarations
Unit display format
Loops
