Ctype - Perl extension for character class testing
use Ctype qw(toupper); # plain style $uppercased = toupper("a"); # OO style $obj = Ctype->new("a"); $uppercased = $obj->uppercased;
Ctype provides character class testing to Perl programs. The
ctype.h functions are part of the C library (in your system!). Ctype also supports the Perl library
ctype functions. To use the Perl library
ctype functions, set the variable $Ctype::useperlfns to a non-false value. For the OO interface, call the method $obj->useperlfns to toggle it.
The OO interface constructor is called (by convention)
new is called with a character as an argument. It creates a Ctype object that will perform tests on the character when called as an object method. These are the relations to the regular C functions:
isalphanumeric isalnum isalphabetic isalpha isnumerical isdigit islowercase islower iswhitespace isspace isuppercase isupper ishexdigit isxdigit tolowercase tolower touppercase toupper
setchar method sets the character stored in the object.
