we might want to extend this further to handle environments like electron, I'm not sure of the best approach. Here's what we do in yargs.

perhaps open a tracking ticket to add a clearer type checking message eventually 😆 (if you'd like to land this with Whoops!).

for this first implementation we're only supporting --foo, --foo bar?

I read the FAQ, and opened #2.

For test coverage, which I think will be helpful for writing a parser, I suggest we try c8 which is what I've got the Node.js using 😄
Also, I think it would be nice to pull in standard or standardx as a linter, I usually do this:
"posttest": "standard",
"fix": "standard --fix"
That way someone can just run npm run fix, to address linting issues.

let's please just use eslint, regardless of how it's configured; that package's name doesn't need any additional artificial inflation of its standard-ness.

I've captured the comments in this PR as issues and will land the PR as is. |
Initial work here for review and consideration.
Please review: @bcoe @darcyclarke @ruyadorno @iansu
Thanks!
