(derive) Ensure #[clap(...)] attribute still works
[4.0.0] - 2022-09-28
Highlights
Arg::num_args(range)
Clap has had several ways for controlling how many values will be captured without always being clear on how they interacted, including
Arg::multiple_values(true)
Arg::number_of_values(4)
Arg::min_values(2)
Arg::max_values(20)
Arg::takes_value(true)
These have now all been collapsed into Arg::num_args which accepts both
single values and ranges of values. num_args controls how many raw arguments
on the command line will be captured as values per occurrence and independent
of value delimiters.
Clap strives to give a polished CLI experience out of the box with little
ceremony. With some feedback that has accumulated over time, we took this
release as an opportunity to re-evaluate our --help output to make sure it is
meeting that goal.
In doing this evaluation, we wanted to keep in mind:
Whether other CLIs had ideas that make sense to apply
Providing an experience that fits within the rest of applications and works across all shells
