Convert Unix style permissions to strings like ls (0755 => 'rwxr-xr-x')

I wrote this module to make it easy to print out nice looking permissions in my scripts before calling fs.chmod for the user.

Examples

Given

var perms = require('perms');

Convert a mode to a human-readable string like ls(1) generates

var p = perms.toString('0755');
console.log(p);

yields

rwxr-xr-x

Also handles special permissions

var p = perms.toString('6660');
console.log(p);

yields

rwSrwS---

Go backwards as well!

var mode = perms.toMode('rwxr-xr-t');
console.log(mode);

yields

1755

NOTE: This module makes it super tempting to parse ls(1)... don't do that!
