fix(help)!: Make `DeriveDisplayOrder` the default, removing it Force sorting with `next_display_order(None)` Fixes #2808 2022-07-22 20:43:49 +00:00			`use clap::Parser;`
docs: Re-work examples This creates distinct tutorial examples from complex feature examples (more how-tos). Both sets are getting builder / derive versions (at least the critical ones). 2021-11-30 18:30:19 +00:00

docs(examples): Steer people to know about about vs long_about `#[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. 2022-01-11 00:47:20 +00:00			`#[clap(author, version, about, long_about = None)]`
feat: Replace core set of AppSettings with functions This is a part of #2717 Some settings didn't get getters because - They are transient parse settings (e.g. ignore errors) - They get propagated to args and should be checked there `is_allow_hyphen_values_set` is a curious case. In some cases, we only check the app and not an arg. This seems suspicious. 2022-02-10 17:51:40 +00:00			`#[clap(allow_negative_numbers = true)]`
