`-h` (short help) still shows the same.
This gates it behind an `unstable-v4` feature flag to avoid disrupting users who set the help without knowing where all it shows up (particularly derive users where `ArgEnum` is automatically extracting the help).
Fixes#3312
3468325b8d and afd0342a added extra context to the README's example. However, when browsing it at docs.rs, the builder link just links back to the page you are own, offering little value.
Instead we'll now link to the tutorial which works as a next step from the example and resolves the "what do we link for the builder api" question.
`#[clap(about)]` only overrides `about`. If the doc comment also sets
`long_about`, it won't be overridden. This change is to help raise
visibility of reseting `long_about` in these cases.
`clap_generate` originally intended to be "generate anything". With
`fig`, we already broke one part out. With #3174's man support, we are
also looking at keeping it separate:
- More freedom to iterate on the API
- Uniqueness (and potential weight) of its dependencies
- man generation is normally more for distribution while completions are
a mix of being distributed with the app or the app generating the
completions (which will be exacerbated if we move most completion
parsing logic to be in Rust)
So `clap_generate` is having a lot more limited of a role than the
original name conveys. I worry the generic name will be a hindrance to
people discovering and using it (yes, documentation can help but there
are limits).
I hesitated because we are on the verge of releasing 3.0. However, doing
it even later will be even more disruptive because more people will be
using it (crates.io lists ~70 people using `clap_generate`).
To ease things, we are still releasing `clap_generate` as a wrapper
around `clap_complete`.
