Add autoVersion and autoHelp options

[angeloashmore]

Fixes #62

Adds autoVersion and autoHelp options. If either is set to false, meow won't handle printing on --version and --help. This would allow for explicit handling of showing either, possibly in a subcommand context.

Note: I had to add an extra \n to the spawn cli and show help screen test to pass. Not sure if this due to my shell?

You can already do this with the help and version option.

By setting the values to false? I would still like meow to handle help and version messages, but not in every case. Sorry, maybe I'm missing something?

Here's my use case:

$ myapp --help

I would like this to print the help message defined for myapp.

$ myapp subcommand --help

myapp calls myapp-subcommand in a child process and passes the arguments. I would like myapp-subcommand's help message to be printed, but myapp is seeing the --help and printing it's own message.

This PR would allow me to disable help and version handling in meow, but still use the showHelp function when necessary.

Another option is to alias the help and version flags in myapp to something else and handle the flags manually, but I thought this might be another option.

@sindresorhus any thoughts on this? I'll close it out if you feel it's unnecessary. 🙂

Sorry for the late response. Yes, this makes sense. Can you remove the false support in the help and version options, as it's no longer needed with this option (in code, test, and readme).

[angeloashmore]

Sorry, I'm way late on revisiting this. Just pushed some commits to the PR.

• Removes false support for help and version
• Adds showVersion function to complement showHelp
• Updates the documentation
