String::Mask

Homepage | Source Code

DESCRIPTION

Mask provides a string utility to manipulate strings in logicomathematical manner, ie. add, subtract, xor, etc.

SYNOPSIS

Mask objects can be created explicitly via #new.

m1 = String::Mask.new("abc..123", '.')
m2 = String::Mask.new("ab..789.", '.')
m1 - m2                             #=> "....789."

But the String#mask extension is much easier to use.

m1 = "abc..123".mask('.')
m2 = "ab..789.".mask('.')
m1 * m2                             #=> "ab..789."

The second operand can be a normal String. Mask will assume it repesents another mask akin to the first.

"abc..123".mask('.') + "ab..789."   #=> "abc.7893"

INSTALL

To install with RubyGems simply open a console and type:

$ gem install strmask
