Merge pull request #2690 from epage/value_name 
fix!: value_name/value_names should not append
 2021-08-13 22:45:59 +01:00

2eb22e2b36 fix!: value_name/value_names should not append 
Instead they should behave like `default_value`/`default_values`.

In implementingt this, I didn't see any reason to be using a `VecMap`.
In fact, this helped simplify the code / make intent clearer.

With this, we are also able to simplify the derive macro work from #2633.

Fixes #2634

BREAKING CHANGE: `value_name`/`value_names` always overwrite, rather
than append.  We expect the impact to be minimal.

2458d3934a test: Cover external subcommand updates 
We don't know enough to do partial updates, so we are only doing full
updates.

Closes #2212

9a180c1511 feat(derive): Specify defaults by native expressions 
Right now
- `default_value="something"` is a raw method
- `default_value` uses native types

This commit splits the meanings
- `default_value="something"` is a raw method
- `default_value_t` uses `T::default()`
- `default_value_t=expr` uses an expression that evaluates to `T`

This is meant to mirror the `value_of` / `value_of_t` API.

At the moment, this is limited to `T: Display` to work with clap's
default system.  Something we can look at in the future is a way to
loosen that restriction.  One quick win is to specialize when `arg_enum`
is set.  The main downside is complicating the processing of attributes
because it then means we need some processed before others.

Since this builds on `clap`s existing default system, this also means
users do not get any performance gains out of using `default_value_t`,
since we still need to parse it but we also need to convert it to a
string.

Fixes #1694
