tilde-expansion

Expand a ~ character to a users home directory like bash

Examples

Given

var tilde = require('tilde-expansion');

You can do basic expansion

tilde('~root', function(s) {
  console.log(s);
});

yields

/root

or even simpler

tilde('~/', function(s) {
  console.log(s);
});

yields

/home/dave/

and get fancy with the PWD

tilde('~+', function(s) {
  console.log(s);
});

yields

/home/dave/dev

Notes

• Any unrecognized expansions will result in the string being unchanged
• The node etc-passwd module is used to determine the home directory of a user
• If the user is not found on the system, the expansion will remain unaltered
• The string must be unquoted for any expansion to take place (see bash(1))

Usage

var tilde = require('tilde-expansion');

Installation

npm install tilde-expansion
