v4.0.0

Breaking changes since v3.0.5

• Removed support for node versions less than v4.0.0

• The method signature changed. If you're passing a custom argv you now do it this way:

  const argv = [ '--log-level', 'info' ]
  commandLineArgs(optionDefinitions, { argv })

  Previously, it was done this way:

  const argv = [ '--log-level', 'info' ]
  commandLineArgs(optionDefinitions, argv)

• String is the new default type function.

If all the following are true then no changes are required to your code

• Your app does not need to run on old nodejs versions
• You don't pass a custom argv
• All your option definitions have a type specified

New feature

• Partial parsing - support for unknown options. See the docs and issue 25 for background.

Other changes

• Fixed #24, #39
• Overhauled the examples
• Refactored internals
• More tests added
