BSON::Regex - BSON type wrapper for regular expressions


version v1.4.0


    use BSON::Types ':all';
    $regex = bson_regex( $pattern );
    $regex = bson_regex( $pattern, $flags );


This module provides a BSON type wrapper for a PCRE regular expression and optional flags.



A string containing a PCRE regular expression pattern (not a "qr" object and without slashes). Default is the empty string.


A string with regular expression flags. Flags will be sorted and duplicates will be removed during object construction. Supported flags include "imxlsu". Invalid flags will cause an exception. Default is the empty string.



    my $qr = $regexp->try_compile;
Tries to compile the "pattern" and "flags" into a reference to a regular expression. If the pattern or flags can't be compiled, a exception will be thrown.
SECURITY NOTE: Executing a regular expression can evaluate arbitrary code if the re 'eval' pragma is in force. You are strongly advised to read re and never to use untrusted input with "try_compile".


If the "BSON_EXTJSON" option is true, returns a hashref compatible with MongoDB's extended JSON <> format, which represents it as a document as follows:
    {"$regex" : "<pattern>", "$options" : "<flags>"}
If the "BSON_EXTJSON" option is false, an error is thrown, as this value can't otherwise be represented in JSON.
