Topics for the "args" chapter

[japaric]

• ~~~os::args~~~: return type, first arg is the program name, number of arguments
• ~~~matching on os::args~~~
• getopts

@vks is working on this

I'd be happy to mentor anyone who wants to work on this!

[vks]

I think getopts was moved out of the standard library. Maybe hint at clap and friends instead?

[steveklabnik]

Or, maybe referring to the Cookbook for "real" argument parsing.

In the initial issue comment, does os::args now refer to the ArgsOs iterator?

[steveklabnik]

Yup! https://doc.rust-lang.org/stable/std/env/fn.args.html and its return type

[steveklabnik]

I'm not sure what the second checkbox is, so I just checked it off.

@steveklabnik awesome, thanks will work on the next PR! 😄

@steveklabnik Having a look at the current args page it looks like the issue has already been addressed... It describes how to get the first argument and the number of arguments. Is there something else we should be adding?

[steveklabnik]

You're totally right, looks great to me. Thanks for closing this out!
