[bonus question]how to handle argv for space seperated values?

[linghuaj]

Hi @codepathreview @codepath I have a question about the prework for the bonus part one.(allow child process for the process) The questions asks you to "bode index --exec grep require"

but the second part of the arguments get pushed to a anonymous property when i took a took at argv.exec.

bode index --exec grep require niuniu -x niuniu2 niuniu3

I'm trying something like this, and i was expecting in my code, i am able to get something like

exec: ['grep', 'require']
x:['niuniu2', 'niuniu3']

but instead, i'm getting

argv { _: [ 'require', 'niuniu', 'niuniu3' ],
  exec: 'grep',
  x: 'niuniu2',
  host: 'localhost',
  '$0': 'index' }

where all the space seperated values are pushed in to one arr. Any suggestion?

thanks

Unfortunately, no. .nargs(key, number) let's you grab a array of values and hardcoded length for a given flag, but it doesn't support variadic flags unfortunately.

You can however use another package! Checkout the variadic argument support in commander (an even more popular and powerful options parsing library).

Hey @CrabDude

Thanks a lot for the answer, I'll give it a try

@CrabDude hey adam, I took a look through commander documentation. looks like commander only support last argument as variadic.

"The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to append ... to the argument name."

Ah, yes. That's unfortunate. At that point would need to implement the functionality yourself if you wanted to support multiple variadic arguments.
