pub type Command<'help> = App<'help>;
Expand description
Build a command-line interface.
This includes defining arguments, subcommands, parser behavior, and help output.
Once all configuration is complete,
the Command::get_matches
family of methods starts the runtime-parsing
process. These methods then return information about the user supplied
arguments (or lack thereof).
When deriving a Parser
, you can use
CommandFactory::command
to access the
Command
.
- Basic API
- Application-wide Settings
- Command-specific Settings
- Subcommand-specific Settings
- Reflection
Examples
let m = Command::new("My Program")
.author("Me, me@mail.com")
.version("1.0.2")
.about("Explains in brief what the program does")
.arg(
Arg::new("in_file")
)
.after_help("Longer explanation to appear after the options when \
displaying the help information from --help or -h")
.get_matches();
// Your program logic starts here...
