 // app_e_p.exec( a,b );

/* important */
/* important */
/* important */
// variable in exel_perl must be a global var
$abc = 'text of $abc var.';	
var perl_stm = 	`
	 $abc= $abc x 2;
	 $abc =~ s/text/TEXT/g; // use your comment
	 (($abc));  # another comment style,define return var
`;

// var ret_obj = app.e_pl ()... // also works 
var ret_obj = exec_perl ( 
	'$abc', 	// caution! it's name of var, not value
	perl_stm
);
console.log( $abc ) ; 
// console: TEXT of $abc var.TEXT of $abc var.
console.log ( ret_obj.ans );
console.log ( ret_obj.perl_stm ); // show the run statement,for debugging

About

Why we need exec_perl

• Node.js is fast, Perl is fast and freedomly, how to choose from? Why don't we have both? I am a perl-er, and also a node.js-er, I am greedy~ .I take both _-:)

Project goals

• Embeded perl script into Node.js,and have them worked perfectly togather
