Changes paths that have

  • The current working directory with .
  • node_modules/<module> with <module>@<version>

Adds a footer with

  • The current working directory
  • An ISO date and node version from were error was thrown

api

var herro = require('herro');

The module.exports two functions

  • herro.Herror
  • herro.global

Herror

function Herror(String message)

Error class with paths on its stack trace as <module>@<version> instead of node_modules/<module>. Inherits from the Error class.

arguments

  • message type string message for the error

returns

  • a new error instance

usage

var Herror = require('herro').Herror;

if('something broke'){
 throw new Herror('oh, no, you did not!');
}

global

function global([Boolean flag])

If flag is truthy or undefined, it will make all stack traces have <module>@<version> instead of node_modules/<module>. If flag is falsy it will revert stacktraces to their default format.

usage

var herro = require('herro');

herro.global(); // make it global
herro.global(false); // go back to the normal stack format

install

With npm

npm install herro

  npmize
    ✓ CWD/node_modules/module/file.js into module@version
    ✓ CWD/node_modules/m1/node_modules/m2/file.js into m1@version/m2@version2
