Summary

file-overlap provides utitlies for getting the overlap and difference of two paths.

Usage

.overlap returns the path that two paths have in common.

.differenceRight returns the path that the second argument has the the first doesn't.

.tail returns the difference at the end of the first argument when compared to b.

var overlap = require('file-overlap');

console.log( overlap.overlap('/foo/bar/baz', 'bar/baz/banana.js') ); // 'bar/baz'
console.log( overlap.difference('/foo/bar/baz', 'bar/baz/banana.js') ); // '/foo'
console.log( overlap.differenceRight('/foo/bar/baz', 'bar/baz/banana.js') ); // 'banana.js'
console.log( overlap.tail('/foo/bar/baz/banana.js', '/foo/bar/baz') ); // 'banana.js'

// N.B. Tail does not work in reverse (right now).
console.log( overlap.tail('/foo/bar/baz', '/foo/bar/baz/banana.js') ); // '/foo/bar/baz' <- obviously not correct
