Readme

Pipetteur
NPM version Build Status Coverage Status Dependency Status
A module to find all color syntax substrings in a string with their offsets and their color instance. It's an automated eyedropper tool for your text, css, html, svg etc.
It takes a single string argument and returns an array of objects like this:
{
    match: '#FF0000', // The found color match
    index: 0, // Zero based index of the match in the string
    line: 1, // 1-based line number
    column: 1, // 1-based column number
    color: <one-color>
}

The color object returned is an instance of one-color, giving you instant access to highlevel color manipulation without having to think about color space conversions.

Usage

var pipetteur = require('pipetteur');

pipetteur('Roses are rgb(255,0,0), violet are #00f');

[ { index: 10,
    line: 1,
