What would the parsed output be prior to your fix? This output seems good, I'm just not 100% understanding the original bug.

I just realized I must have screwed up the test assertion when I cleaned up these commits a while ago. I just amended the assertion so it matches the expected unknown-options-as-args behavior. Let me know if the output still looks good to you.

The full parsed output without the fix is

{ _: [ '-v', '--long', 'arg', './file.js', 'barbar' ], foo: true }

As you can see, yargs ignores halt-at-non-option and parses the --foo and -- options anyway.

Thanks for clarifying, this fix looks right to me 👍

const parse = parser(
['-v', '--long', 'arg', './file.js', '--foo', '--', 'barbar'],
{ configuration: { 'halt-at-non-option': true, 'unknown-options-as-args': true }, boolean: ['foo'] }
)
parse.should.deep.equal({
_: ['-v', '--long', 'arg', './file.js', '--foo', '--', 'barbar']
})
})
})
