.format support

[bevacqua]

It would be nice to have format as part of the API

console.log(chalk.underline.red.format("Detected %s Error(s)", errors.length));

Not sure if @sindresorhus wants to include this functionality or not, but for the time being you can use the sprintf package to achieve this.

npm install chalk sprintf

var vsprintf = require('sprintf').vsprintf,
    chalk = require('chalk');

var errors = ["File not found."];

console.log(vsprintf(chalk.underline.red("Detected %s Error(s)"), [errors.length]));

No need. console.log already supports simple string substitution.

This should work:

console.log(chalk.underline.red('Detected %d Error(s)'), 1);

I've added an example to the readme ;)

The point was using util.format and proving some sugar in the chalk api

I prefer to keep Chalk focused and your example is actually more verbose than the above. Do feel free to create a tool for this using Chalk though, if this doesn't work for you. That's really what it's for; the most low-level way to colorize.
