JE, version 0.006

JE is a pure-Perl ECMAScript (JavaScript) engine.

This is still an alpha release. All JavaScript syntax should be parsed
and executed correctly now. The core objects are not yet complete.

If  you have the time and the interest,  please experiment with this
module. If you have any ideas as to how the API could be improved or
reworked, please e-mail me.


CHANGES IN THIS RELEASE

Added the TypeError and RangeError classes

Finished the Function and Array classes (except for
Function.prototype.toString)

Half-finished the String class

Fixed various parser bugs

Added the JE::String::surrogify function


TO DO

- Finish the core object classes
- Add helpful error messages
- Provide a way to bind Perl classes to JS
- Determine some logical way of dealing with locale settings (for
  String.prototype.localeCompare, et al.)
- Write lots and lots and lots of tests, at the same time fixing all
  the bugs they bring to light.
- Make tainted JS code run safely
- Deal with circular references somehow
- Optimise JS functions by turning them into Perl subs (but run benchmarks
  first to see whether this would actually speed things up) (I'm having
  second thoughts about this one)


INSTALLATION

The easiest way to install this module is to use the CPAN module or the
cpan script:

    [sudo] perl -MCPAN -e "install JE"

    [sudo] cpan
    cpan> install JE

Or you can use the following:

    perl Makefile.PL
    make
    make test
    [sudo] make install


DEPENDENCIES

DOCUMENTATION

After installing, you can find documentation for this module with the 
perldoc command.

    perldoc JE

Or try using man (it's faster, in my experience):

    man JE
