Enum clap::ColorChoice

pub enum ColorChoice {
    Auto,
    Always,
    Never,
}

Represents the color preferences for program output

Variants

Auto

Enables colored output only when the output is going to a terminal or TTY.

NOTE: This is the default behavior of clap.

Platform Specific

This setting only applies to Unix, Linux, and macOS (i.e. non-Windows platforms).

Examples

Command::new("myprog")
   .color(ColorChoice::Auto)
   .get_matches();

Always

Enables colored output regardless of whether or not the output is going to a terminal/TTY.

Platform Specific

This setting only applies to Unix, Linux, and macOS (i.e. non-Windows platforms).

Examples

Command::new("myprog")
   .color(ColorChoice::Always)
   .get_matches();

Never

Disables colored output no matter if the output is going to a terminal/TTY, or not.

Platform Specific

This setting only applies to Unix, Linux, and macOS (i.e. non-Windows platforms)

Examples

Command::new("myprog")
   .color(ColorChoice::Never)
   .get_matches();
