imp(validator): Case-insensitive required_if_eq when arg is case-insensitive
impl<'help> Arg<'help> { /// // We did use --other=special so "cfg" had become required but was missing. /// assert!(res.is_err()); /// assert_eq!(res.unwrap_err().kind, ErrorKind::MissingRequiredArgument);+ ///+ /// let res = App::new("prog")+ /// .arg(Arg::new("cfg")+ /// .takes_value(true)+ /// .required_if_eq("other", "special")+ /// .long("config"))+ /// .arg(Arg::new("other")+ /// .long("other")+ /// .takes_value(true))+ /// .try_get_matches_from(vec![+ /// "prog", "--other", "SPECIAL"+ /// ]);+ ///+ /// // By default, the comparison is case-sensitive, so "cfg" wasn't required+ /// assert!(res.is_ok());+ ///+ /// let res = App::new("prog")+ /// .arg(Arg::new("cfg")+ /// .takes_value(true)+ /// .required_if_eq("other", "special")+ /// .long("config"))+ /// .arg(Arg::new("other")+ /// .long("other")+ /// .case_insensitive(true)+ /// .takes_value(true))+ /// .try_get_matches_from(vec![+ /// "prog", "--other", "SPECIAL"+ /// ]);+ ///+ /// // However, case-insensitive comparisons can be enabled.

Good point, and that was my intention so that they would all the equality comparisons would have consistent behavior. I've added the interaction to the documentation for Arg::case_insensitive, and rebased to master to address the linting error.

issue commentclap-rs/clap
@CreepySkeleton I've been playing around with the code and I think we could get it to work to support dynamic completion of a simple flag value. I haven't looked at the shell completion logic but I am thinking in the direction of only calling your_app --autocomplete 7 ... if we are at a flag position with automatic expansion.
It would be super cool, to reduce all shell autocomplete logic to calling out to your prog with the --autocomplete argument but that would probably require a different parser or a lot more work.
Anyways, if we use the --autocomplete "API", we can step by step expand it to cover more use cases.

Implemented as AppSetting::Ignore errors as suggested by @CreepySkeleton in https://github.com/clap-rs/clap/issues/1880#issuecomment-637779787.
This is not a complete implementation but it works already in surprisingly many situations.

Minimal reproducible code
Hi, I tried to generate on my little project https://github.com/mothsART/pouf autocompletion on zsh.
Cargo build produce this file : https://github.com/mothsART/pouf/blob/8335f28d5ea9c6a3916a3d5098481e3aaab9f45d/_pouf
and I included with :
source _pouf
This produce an error like :
_arguments:comparguments:312: can only be called from completion function
If i manualy delete _pouf "$@", everything seems correct.
Same issue with 2 opposite version of Zsh : Zsh 5.1 and 5.8 (the last one).
Finally, the script suggest me
compdef _pouf pouf
but it doesn't work. I replace it with :
compdef _pouf pouf
Steps to reproduce the bug with the above code
cargo build
