Re: Detecting if a string is a regular expression

in reply to Detecting if a string is a regular expression

You could create a regex that checks the string for the characters you want to allow, e.g.:

sub isStrOK {
    return $_[0] =~ /\A[\s\w]+\z/;
}

The above's not intended to be exhaustive for allowable characters, but only an example.
