NAME

Fauxtobox - fake autoboxing (call methods on plain scalars)

SYNOPSIS

 use Fauxtobox;

 my $n = "zomg"->$_length;  # $n = 4
 print $n->$_sqrt;          # "2"

 # ... and many methods more

DESCRIPTION

This module provides fake autoboxing support. Autoboxing means being able to call methods on non-objects like 42 or 'hello' because the language will automatically wrap them in objects. If you want that, see autobox.

What this module does is much simpler: It exports a bunch of variables that can be used like methods. These method variables can be used on any value, not just objects.

Exported methods

By default everything listed below is exported. If you don't want that, you can explicitly list the variables you want:

  use Fauxtobox qw($_defined $_length $_apply);

For convenience you can omit the leading $_ in the import list:

  use Fauxtobox qw(defined length apply);

Several functions in Perl take or return lists. In general, the method equivalents of these take and return array references instead, to make method chaining possible. Exceptions are noted below.

$_apply

$X->$_apply($F) is equivalent to $F->($X), so e.g. "abc"->$_apply(\&display) is equivalent to display("abc").

$_list

$X->$_list returns %{$X} if $X is a hash reference and @{$X} otherwise. This is useful if you have an array reference and want to turn it into a list of its values.

$_qr

$X->$_qr is equivalent to qr/$X/. $X->$_qr($FLAGS) is equivalent to qr/$X/$FLAGS except that's a syntax error, but e.g. '^hello\s+world'->$_qr('i') is equivalent to qr/^hello\s+world/i.

See "qr" in perlfunc.

$X->$_m($REGEX) is equivalent to $X =~ m/$REGEX/.
