In considering potential work for #2683, I realized we might need a type to carry data for
each of the `multiple_values`. `ArgValue` works both for that and for
possible values, so we need to come up with a better name for one or
both. Changing `ArgValue`s name now would be ideal since its new in
clap3 and by renaming it, we can reduce churn for users.
While thinking about this, I realized I regularly get these mixed
up, so renaming `ArgValue` to `PossibleValue` I think will help clear
things up, regardless of #2683.

`App::get_matches` lazily post-processes `App`s and `Arg`s so we don't
do it to subcommands that are never run (downside being people have to
exercise their full app to get debug_asserts).
`clap_generate` was only post-processing the top-level `App` and `Arg`s,
ignoring the sub-commands. In #2858, we noticed that `--version` was
being left in the completions instead of being removed during the
`_build` step. We would also have an incorrect `num_vals` and a host of
other problems.
This change adds a `App::_build_all` function for `clap_generate` to use
to eagerly build everything. By having it there, we make sure
everywhere that needs eager building, gets it (like some tests).
In `clap_generate::utils`, we add a unit test to ensure the subcommand's
`--version` was removed.
For some other tests specifying `.version()`, I added
`AppSettings::PropagateVersion` to make it behave more consistently.
The places I didn't were generally where the version was conditionally
set.
For `clap_generate/tests/generate_completions.rs`, I had to adjust the
`conflicts_with` because the subcommand was inheriting the argument with
it defined *but* the subcommand did not have the argument, tripping up a
debug assert.
Fixes#2860
This is a followup to #2721 where we decided to remove all of the
helpers from the trait. They are now in a `utils` mod. A part of me
wants this module to be private but it'd be a lot to duplicate for the
split out modules.
Note: this doesn't update fig. Fig was never added to the workspace and
is already broken (and not just from #2721). My plan is to get this
merged and then fix Fig, rather than fix it in multiple passes.
In #2270, its brought up to solve this at the `cargo workspace publish`
level. However, copying the files is a 5s fix without any design work,
it doesn't seem like support within an external tool should block us
from getting this fix into users hands. Once `cargo workspace publish`
supports this and if we are still using it, we can re-evaluate.
Fixes#2270
The `display-suffix` option for `edit:complex-candidate` was [deprecated in Elvish v0.14.0][1] and
removed in v0.15.0 (latest version is v0.16.3), so this commit changes the Elvish completions
generation to use the `display` option instead.
Additionally, this commit changes assignments to use the `var` and `set` keywords as using
`name = value` without these keywords ('legacy assignment form') [will be deprecated][2].

* feat(arg_value): ArgValue can be used for possible_values
Through the ArgValue it is possible:
* `hide` possible_values from showing in completion, help and validation
* add `about` to possible_values in completion
* Resolved a few change-requests by epage
* make clippy happy
* add ArgValue::get_visible_value
* remove verbose destructering
* rename ArgValue::get_hidden to ArgValue::is_hidden
* add test for help output of hidden ArgValues
* Documentation for ArgValue
There is an issue that required to implement From<&ArgValue> for
ArgValue. We should probably find a solution without that.
* fix requested changes by epage
* fix formatting
* add deref in possible_values call to remove From<&&str>
* make clippy happy
* use copied() instad of map(|v|*v)
* Finishing up for merge, hopefully
* changes requested by pksunkara
* fix(generate): Better subcommand completion in fish
* Prevent completing subcommands that were already completed
* Make sure all parent subcommands actually existent
Partially fixes#2715
* Added Test
* fix(generate) Improve subcommand testing
This now also disables the completion of sub_subcommands options for
subcommands.
This returns `"{a\t,b\t}"` instead of `"a b"` for possible_values
completion. Therefore fish displays and therefor hides the empty
description after the `\t`.
Fixes#2727
This provides a skeleton README for `clap_generate`, including a
one-line summary and a link to the docs to guide people to the examples
there.
In doing so, I tried to clarify and be consistent in what role
this crate plays. While it is very general, being too general in the
description can lead people to not understand where they could use it.
Fixes#1711
