Instead of using Format::Error directly, we need to use a Colorizer to
make sure that the message only gets colorized when it is appropriate
to do so.
Fixes#775
The implementation is basically manually expanded lazy_static! macro
(with some hand-crafted simplifications and inlining), since you can't
use extern crates (and therefore import macros therefrom) in macros.
This ensures that you get this:
p:\Rust\http>target\debug\http -h
http 0.1.0

Closes#779
Since ZSH completions use `[ and ]` for descriptions, but clap args use `[ and ]` for possible
values and other auxillary arg information, this was creating a conflict. clap now escapes any
square brackets before writing the help, i.e. `\\[ and \\]` which removes conflicts.
Alternatives would be to switch `[ and ]` for `( and )` but this would create a slight difference
in help messages and completions.
Closes#771
imp(Completions): adds fallbacks to Bash completions
With these options, in case the completion function cannot provide suggestions, Bash will perform its default completions, based on e.g. files, directories, and variable names.
This is particularly noticeable in tools that operate on paths, like ripgrep: when I type `rg should_panic te<TAB>`, I want the shell to autocomplete `tests/`, but right now the completion script will simply beep without any suggestions.
With these options, in case the completion function cannot provide
suggestions, Bash will perform its default completions, based on e.g.
files, directories, and variable names. This is particularly useful for
argument values.
Prior to this commit setting `number_of_values(1)` and `multiple(true)` would cause the help
message alignment to be off. This commit fixes that.
Closes#760
