NAME

       Data::JavaScript::Anon - Dump big dumb Perl structs to anonymous JavaScript structs

SYNOPSIS

	 # Dump an arbitrary structure to javascript
	 Data::JavaScript::Anon->anon_dump( [ 'a', 'b', { a => 1, b => 2 } ] );

DESCRIPTION

       Data::JavaScript::Anon provides the ability to dump large simple data structures to JavaScript. That is, things that don't need to be a
       class, or have special methods or whatever.

       The method it uses is to write anonymous variables, in the same way you would in Perl. The following shows some examples.

	 # Perl anonymous array
	 [ 1, 'a', 'Foo Bar' ]

	 # JavaScript equivalent ( yes, it's exactly the same )
	 [ 1, 'a', 'Foo Bar' ]

	 # Perl anonymous hash
	 { foo => 1, bar => 'bar' }

	 # JavaScript equivalent
	 { foo: 1, bar: 'bar' }

       One advantage of doing it in this method is that you do not have to co-ordinate variable names between your HTML templates and Perl. You
       could use a simple Template Toolkit phrase like the following to get data into your HTML templates.

	 var javascript_data = [% data %];

       In this way, it doesn't matter WHAT the HTML template calls a particular variables, the data dumps just the same. This could help you keep
       the work of JavaScript and Perl programmers ( assuming you were using different people ) seperate, without creating cross-dependencies
       between their code, such as variable names.

       The variables you dump can also be of arbitrary depth and complexity, with a few limitations.

       ARRAY and HASH only
	   Since arrays and hashs are all that is supported by JavaScript, they are the only things you can use in your structs. Any references or
	   a different underlying type will be detected and an error returned.

	   Note that Data::JavaScript::Anon will use the UNDERLYING type of the data. This means that the blessed classes or objects will be
	   ignored and their data based on the object's underlying implementation type.

	   This can be a positive thing, as you can put objects for which you expect a certain dump structure into the data to dump, and it will
	   convert to unblessed, more stupid, JavaScript objects cleanly.

       No Circular References
	   Since circular references can't be defined in a single anonymous struct, they are not allowed. Try something like Data::JavaScript
	   instead.  Although not supported, they will be detected, and an error returned.

MAIN METHODS

       All methods are called as methods directly, in the form "Data::JavaScript::Anon->anon_dump( [ 'etc' ] )".

   anon_dump STRUCT
       The main method of the class, anon_dump takes a single arbitrary data struct, and converts it into an anonymous JavaScript struct.

       If needed, the argument can even be a normal text string, although it wouldn't do a lot to it. :)

       Returns a string containing the JavaScript struct on success, or "undef" if an error is found.

   var_dump $name, STRUCT
       As above, but the "var_dump" method allows you to specify a variable name, with the resulting JavaScript being "var name = struct;". Note
       that the method WILL put the trailing semi-colon on the string.

   script_wrap $javascript
       The "script_wrap" method is a quick way of wrapping a normal JavaScript html tag around your JavaScript.

   is_a_number $scalar
       When generating the javascript, numbers will be printed directly and not quoted. The "is_a_number" method provides convenient access to the
       test that is used to see if something is a number. The test handles just about everything legal in JavaScript, with the one exception of
       the exotics, such as Infinite, -Infinit and NaN.

       Returns true is a scalar is numeric, or false otherwise.

       You may also access method in using an instantiated object.

   new HASH
       This will create a Data::JavaScript::Anon object that will allow you to change some of the default behaviors of some methods.

	   Options:
	       quote_char  : Set the quote_char for stirng scalars. Default is '"'.

SECONDARY METHODS

       The following are a little less general, but may be of some use.

   var_scalar $name, $scalar
       Creates a named variable from a scalar reference.

   var_array $name, @array
       Creates a named variable from an array reference.

   var_hash $name, \%hash
       Creates a named variable from a hash reference.

   anon_scalar $scalar
       Creates an anonymous JavaScript value from a scalar reference.

   anon_array @array
       Creates an anonymous JavaScript array from an array reference.

   anon_hash \%hash
       Creates an anonymous JavaScript object from a hash reference.

   anon_hash_key $value
       Applys the formatting for a key in a JavaScript object
