buffer-index-of-items v0.0.3

buffer-index-of-items.js

For when you need to find a set of tokens in a buffer. You can't use RegExp on Buffers without casting it to a string.

But you can use buffer-index-of-items, which will make you super sexy. See the API documents for MD or HTML in the same directory.

There are 2 ways to use it:

const indexOfItems = require( './buffer-index-of-items.js' )
        .create( {'one': 1, 'two': 2, 'three' : 3, 'four': 4} )
    , buffer = Buffer.from( 'one, two, three and four.  Can I have a little more?' )
    ;
console.log( indexOfItems( buffer ), indexOfItems.index, indexOfItems.lastIndex );  // 1, 0, 3
console.log( indexOfItems( buffer ), indexOfItems.index, indexOfItems.lastIndex );  // 2, 5, 8
console.log( indexOfItems( buffer ), indexOfItems.index, indexOfItems.lastIndex );  // 3, 10, 15
console.log( indexOfItems( buffer ), indexOfItems.index, indexOfItems.lastIndex );  // 4, 20, 24
console.log( indexOfItems( buffer ), indexOfItems.index, indexOfItems.lastIndex );  // undefined, 0, 0

or:

const indexOfItems = require( './buffer-index-of-items.js' )
    , buffer = Buffer.from( 'one, two, three and four.  Can I have a little more?' )
    , map = {'one': 1, 'two': 2, 'three' : 3, 'four': 4}
    ;
console.log( indexOfItems( map, buffer ) );   // 0
console.log( indexOfItems( map, buffer ) );   // 5
console.log( indexOfItems( map, buffer ) );   // 10
console.log( indexOfItems( map, buffer ) );   // 20
console.log( indexOfItems( map, buffer ) );   // -1

Hope it solves all your simplier buffer parsing problems.
