Assessment

This issue has not been assessed yet.

Description

it often makes sense to have the same argument repeated multiple times (both named and positional)

e.g. with arg it's possible to do something like this:

const args = arg({
  '--foo': [String]
} as const, { permissive: true })

console.log(args)

which would result in something like this:

$ node test.js --foo=1 --foo=2 1 2 3 4
{
  _: ['1', '2', '3', '4'],
  '--foo': ['1', '2'],
}

this is currently not possible with brocli however :c
the best workaround currently is to use e.g. comma delimiter and manually split them, which is obviously not ideal – you have to account for the comma being a part of one of the items, and it also looks awkward as positional args

my proposed api would look something like this:

const foo = command({
  name: 'foo',
  options: {
    foo: string().repeated(),
    bar: positional().repeated()
  },
  handler: console.log
})

which would print a similar output to the above
