This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of command-line-args.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right?
Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project ✨

You rock!

GitHub Release

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.

New feature

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