cde1a2d218 regex: Introduce convenience Cow-wrapper RegexRef 
As previously discussed on [GitHub], this commit introduces a Cow-like
wrapper RegexRef to enable both `Regex` as well as `&Regex` as
arguments.

It also introduces a new module in the `build:arg` path to remove
clutter from the main module. For more information see #2073.

8cb9a7d486 Add new "regex" feature 
This commit introduces a new feature called `"regex"`. It adds a new
function `validator_regex` to `Arg` and was inspired by the discussion
in #1968. The name `validator_regex` was chosen instead of
`regex_validator` to make sure that the developer keeps in mind that
there may only be a single `Validator` on an `Arg`.

The feature can be used with YAML files, however there is no proper
pattern in `clap_app!` (yet).

85d3daa8c1 Use a different default template when there are no args.

2b101ad7e5 Properly handle YAML null macros for default_value_if 
The macro `yaml_opt_str` is only used in `yaml_tuple3`, which again is
only used for `default_value_if`. Unfortunately, the current test
doesn't make sense, as a v.is_null() indicates a Yaml::Null, on wich
`as_str()` always returns `None`. Instead, the condition should be
negated, as the documentation of `default_value_if` hints:

> **NOTE:** If using YAML the values should be laid out as
> follows (`None` can be represented as `null` in YAML)

The case `$v.is_null()` should therefore lead to `None`, whereas all
other cases should be interpreted `as_str()`.

Previously there were separate tags for this, {before-help-padded} and
{after-help-padded}. Those have been removed and the default ones
given their behavior.
 2020-08-14 09:14:10 -07:00
Matt Kantor
a87320ae88 Use a template to produce the default help message. 
This makes some changes to the template system:

- Template tags for optional items (like {author}) now expand to
  nothing when the value is unset instead of a default string (like
  "unknown author").
- Many template tags now emit line-wrapped output to match
  write_default_help.
- Items with long variants now expand to the appropriate thing for -h
  vs --help.
- The now-obsolete {long-about} tag has been removed.
- A few new tags have been added.

These are externally-visible changes, but if this makes it into 3.0
that's probably reasonable?

Note that line-wrapping can have some odd edge cases since it does not
account for preceding/trailing characters on the same line as the tag.
This is already the case in master, but will affect some additional
tags with this changeset. See #2065 for details.

Closes #2002.

6ddf940ac3 fix: conflicts between flag scs and args alias 
When debug_assertions flag is active, properly handles conflicts between

aliases prevents self conflicts where the alias and the flag subcomand
were the same.

5db25e6a72 refractor: improved parser ergonomics
