Required arguments

[fretn]

Now everything is optional, is there a possibility to make a flag required ?

for example

./myapp --server myapp.com

and when --server flag is not passed the app throws an error.

or is this already possible and I'm just looking over it ?

I know I can go manually over all the flags and throw an error, but I wonder if there is an automatic way

No, there's not currently a way to mark a field as required.

Maybe we can add an additional item required to the definition, like:

#[options(required, help = "host to connect", meta = "HOST")]
server: String,

If the flag is not present, returns something like:

gumdrop::Error::missing_required_flag("server")

[Murarth]

I've just pushed a commit that implements a required flag for options.

@fretn: If this satisfies your use case, feel free to close this issue. If not, further comments are welcome.

Can’t test until next week but it looks like what I needed. Great work.
