pub struct BoolishValueParser {}

Expand description

Parse bool-like string values, everything else is true

Example

Usage:

let mut cmd = clap::Command::new("raw")
    .arg(
        clap::Arg::new("append")
            .value_parser(clap::builder::BoolishValueParser::new())
            .required(true)
    );

let m = cmd.try_get_matches_from_mut(["cmd", "true"]).unwrap();
let port: bool = *m.get_one("append")
    .expect("required");
assert_eq!(port, true);

Semantics:

let value_parser = clap::builder::BoolishValueParser::new();
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("random")).is_err());
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("")).is_err());
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("100")).is_err());
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("true")).unwrap(), true);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("Yes")).unwrap(), true);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("oN")).unwrap(), true);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("1")).unwrap(), true);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("false")).unwrap(), false);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("No")).unwrap(), false);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("oFF")).unwrap(), false);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("0")).unwrap(), false);
