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
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.
One can now use `Arg::allow_hyphen_values(true)` which will enable `--opt -val` style values only
for the specific arg and not command wide.
Closes#742
Flags, Opts, and Positionals now store their internals using compartmented Base, Valued, and
Switched structs to keep the code duplication down and make it easier to maintain.
Iniside the src/app/parser.rs there have been several changes to make reasoning about the code
easier. Primarily moving related sections out of the large get_matches_with into their own
functions.
Prior to this commit, conflicting error messages and the suggeseted usage would depend on whether
you defined the conflict on both arguments, or just one, and the order in which you specified the
conflicting arguments at runtime.
Now they are symetrical, meaning the suggestions from the error message are consistent, and it no
longer matters if you specify the conflict in one, or both arguments.
Closes#718
