NAME
Acme::Tie::Formatted - embed sprintf() formatting in regular print()
VERSION
This document describes Acme::Tie::Formatted version 0.03
SYNOPSIS
use Tie::Formatted;
print "The value is $format{$number, "%3d"} ",
"(or $format{$number, "%04x"} in hex)\n";
print "some numbers: $format{ 12, 492, 1, 8753, "%04d"}\n";DESCRIPTION
This module creates a global read-only hash, %format, for formatting data items with standard sprintf format specifications. Since it's a hash, you can interpolate it into strings as well as use it standalone.
The hash should be "accessed" with two or more "keys". The last key is interpreted as a sprintf format for each data item specified in the preceeding arguments. This allows you to format multiple items at once using the same format for each.
Alternate name
If you prefer, you can specify a different name for the magical formatting hash by supplying it as as argument when useing the module:
use Tie::Formatted qw(z);This makes %z the magic hash instead.
print "This is hex: $z{255, "%04x"}\n";Tie::Formatted currently supports only one format in the final argument; this may change if there is demand for it.
DIAGNOSTICS
You can only use %format by accessing it-
You tried to store something in
%format, check if an element exists in it, delete an element, empty out the hash, or access the key in it.None of these operations do anything; only reading elements of the ahsh works.

"We are like dwarfs sitting on the shoulders of giants. We see more than they do, indeed even farther; but not because our sight is better than theirs or because we are taller than they. Our sight is enhanced because they raise us up and increase our stature by their enormous height." - Bernard de Chartes
