scorer

generate the total ordinal score of a string

build status

Idea

The idea is that given an an ASCII or lower-ordinal utf8 string, scorer will give you a "string ordinal", a deterministic number which any set of strings could be sorted by, without direct comparison or having access to the entire set.

The catch is that you must pre-define the max byte length of your index.

One use case could be generating ranks to use with redis sorted sets.

Example

var score = require('scorer')(10);
// we've created a scoring function with a max byte length of 10.
console.log(score('Carlos Rodriguez'));
// the result is actually an instance of justmoon/node-bignum, with a special
// toString() method that zero-pads the value.
// <BigNum 067097114108111115032082111100>
console.log(score('Carlos Rodriguez').toNumber());
// 6.709711410811112e+28
