je::object::regexp
JE::Object::RegExp(3pm) User Contributed Perl Documentation JE::Object::RegExp(3pm)
NAME
JE::Object::RegExp - JavaScript regular expression (RegExp object) class
SYNOPSIS
use JE;
use JE::Object::RegExp;
$j = new JE;
$js_regexp = new JE::Object::RegExp $j, "(.*)", 'ims';
$perl_qr = $js_regexp->value;
$some_string =~ $js_regexp; # You can use it as a qr//
DESCRIPTION
This class implements JavaScript regular expressions for JE.
See JE::Types for a description of most of the interface. Only what is specific to JE::Object::RegExp is explained here.
A RegExp object will stringify the same way as a "qr//", so that you can use "=~" on it. This is different from the return value of the
"to_string" method (the way it stringifies in JS).
Since JE's regular expressions use Perl's engine underneath, the features that Perl provides that are not part of the ECMAScript spec are
supported, except for "(?s)" and "(?m)", which don't do anything, and "(?|...)", which is unpredictable.
In versions prior to 0.042, a hyphen adjacent to "d", "s" or "w" in a character class would be unpredictable (sometimes a syntax error).
Now it is interpreted literally. This matches what most implementations do, which happens to be the same as Perl's behaviour. (It is a
syntax error in ECMAScript.)
METHODS
value
Returns a Perl "qr//" regular expression.
If the regular expression or the string that is being matched against it contains characters outside the Basic Multilingual Plane
(whose character codes exceed 0xffff), the behavior is undefined--for now at least. I still need to solve the problem caused by JS's
unintuitive use of raw surrogates. (In JS, "/../" will match a surrogate pair, which is considered to be one character in Perl. This
means that the same regexp matched against the same string will produce different results in Perl and JS.)
class
Returns the string 'RegExp'.
