* Clap has dependencies even with all features disabled.
* The "nightly" feature does nothing, so don't mention it.
* Explain the difference between "unstable" and "nightly" better.
* Split features into groups (default, opt-in, clap-development).
* For contributors: update what tests should be run, and remove make command.
* Removes a repeated word and splits up some long markdown lines.
Also groups features by category and dependencies by feature in Cargo.toml.
* feat: adds App::with_defaults to automatically use crate_authors! and crate_version! macros
One can now use
```rust
let a = App::with_defaults("My Program");
// same as
let a2 = App::new("My Program")
.version(crate_version!())
.author(crate_authors!());
```
Closes#600
* imp(YAML Errors): vastly improves error messages when using YAML
When errors are made while developing, the panic error messages have
been improved instead of relying on the default panic message which is
extremely unhelpful.
Closes#574
* imp(Completions): uses standard conventions for bash completion files, namely '{bin}.bash-completion'
Closes#567
* imp(Help): automatically moves help text to the next line and wraps when term width is determined to be too small, or help text is too long
Now `clap` will check if it should automatically place long help
messages on the next line after the flag/option. This is determined by
checking to see if the space taken by flag/option plus spaces and values
doesn't leave enough room for the entirety of the help message, with the
single exception of of if the flag/option/spaces/values is less than 25%
of the width.
Closes#597
* tests: updates help tests to new forced new line rules
* fix(Groups): fixes some usage strings that contain both args in groups and ones that conflict with each other
Args that conflict *and* are in a group will now only display in the
group and not in the usage string itself.
Closes#616
* chore: updates dep graph
Closes#633
* chore: clippy run
* style: changes debug header to match other Rust projects
* chore: increase version
Color are now only used when outputting to a termainal/TTY. There are three new settings as well
which can be used to control color output, they are:
* `AppSettings::ColorAuto`: The default, and will only output color when outputting to a terminal or TTY
* `AppSettings::ColorAlways`: Outputs color no matter where the output is going
* `AppSettings::ColorNever`: Never colors output
This now allows one to use things like command line options, or environmental variables to turn
colored output on/off.
Closes#512
By default `clap` now automatically wraps and aligns help strings to the
term width. i.e.
```
-o, --option <opt> some really long help
text that should be auto aligned but isn't righ
t now
```
Now looks like this:
```
-o, --option <opt> some really long help
text that should be
auto aligned but isn't
right now
```
The wrapping also respects words, and wraps at spaces so as to not cut
words in the middle.
This requires the `libc` dep which is enabled (by default) with the
`wrap_help` cargo feature flag.
Closes#428
