Convert::AnyBase - Convert (encode/decode) numbers to and from an arbitrary base
Version 0.010
use Convert::AnyBase # A hex encoder/decoder my $hex = Convert::AnyBase->new( set => '0123456789abcdef', normalize => sub { lc } ) $hex->encode( 10 ) # a $hex->encode( 100 ) # 64 $hex->decode( 4d2 ) # 1234 # A Crockford encoder/decoder (http://www.crockford.com/wrmg/base32.html) Convert::AnyBase->new( set => ( join '', 0 .. 9, 'a' .. 'h', 'j', 'k', 'm', 'n', 'p' .. 't', 'v', 'w', 'x', 'y', 'z' ), normalize => sub { s/[oO]/0/g; s/[iIlL]/1/g; lc }, # o, O => 0 / i, I, l, L => 1 )
Convert::AnyBase is a tool for converting numbers to and from arbitrary symbol sets.
Create a new converter for the given base. The arguments are:
set A string representing the base 'alphabet'. Each character is a different symbol for the base. The length of the string is the base of the system. The 0-value is the first character, the 1-value is the second character, etc. For example, hexadecimal would be represented by the following: '0123456789abcdef' normalize A code reference for normalizing a string before decoding. The code should operate on $_ and return the sanitized string. The normalizer can be used to consistently lowercase, uppercase, or canocalize input, etc. A normalizer for Crockford (base 32): sub { s/[oO]/0/g; # Translate o/O to 0 s/[iIlL]/1/g; # Translate i/I/l/L to 1 lc; # Lowercase and return the result }
