NAME

Alien::Jerl - micro perl running on JVM (MIPS Interpreter)

SYNOPSIS

            

              
              
java -jar ./lib/alien/jerl.jar --help 
java -jar ./lib/alien/jerl.jar ./perl/fib.pl
            
          

DESCRIPTION

Introduction

Jerl allows perl to run within the JVM (not having to access any external libs).

Details

Jerl allows perl to run within the JVM (not having to access any external libs). Perl has been virtualized to run within the JVM. The current implementation is a version of microperl.

FAQ

            

              
              
https://code.google.com/p/jerl/wiki/JERL_FAQ
            
          

Why

            

              
              
Jerl's purpose is merely to pull Perl into Java (no JNI/native Perl)
Fun
Not speed (see Inline::Java in Alternatives Below)
Use Perl from a Jar
            
          

Why nestedVM / MIPS

            

              
              
nestedVM provided a straightforward means of recompilation
MIPS running within Java is not fast, but there are alternatives for Perl Java integration if speed is a concern(see below)
Implement project in a maintainable way so updates are not too time consuming
            
          

Isn't there something like this already

            

              
              
For speed / optimization Inline::Java works
Check CPAN.org, search Java (there may be something similar)
Goto Perlmonks.org, search Java (there may be something similar)

What Jars are required

            

              
              
jerl.jar is required for jerl
jerl_perlVM.jar is a wapper for interfacing with jerl via Java
you may find both in the eclipse sample project

jerlVersion()

jerlVersion() returns the current version of jerl from the Jar and of this package (multi line)

jerlOneLiner( String )

jerlOneLiner( String ) Returns the output of a single line program which is passed in as an argument

JVM

A working JVM must be available for this to work properly
