Use clap's overrides_with and default_value_if
to better organize options. These are the changes:
- color will have default value of "never" if --vimgrep is given,
and only if no --color option is given
- last overrides previous: --line-number and --no-line-number, --heading
and --no-heading, --with-filename and --no-filename, and --vimgrep and
--count
- no heading will be show if --vimgrep is defined. This worked inside
vim actually because heading is also only shown if tty is stdout
(which is not the case when rg is called from vim).
Unfortunately, clap does not behave like a usual GNU/POSIX in some
cases, as reported in https://github.com/kbknapp/clap-rs/issues/970
and https://github.com/kbknapp/clap-rs/issues/976 (having all the bells
and whistles, on the other hand). So we still have issues like rg
failing when same argument is given more than once (unless for the few
ones marked with `multiple(true)`), or having unintuitive precedence
rules (and probably non-intentional, just there because of clap's
limitations) like:
- --no-filename over --vimgrep
- --no-line-number over --column, --pretty or --vimgrep
- --no-heading over --pretty
regardless of the order in which options where given, where the desired
behavior would be that the last option would override the previous ones
given.
