SLoC
Command-line application framework.
Usage
The command line parser will search for the following pattern:
$ myapp <COMMAND> <FLAGS> <PARAMS> -- <TAIL>
A simple command-line application could look something like this:
use rawcmd::{Context, Command, Flag, Intent};
fn main() {
match Command::with_name("foo")
.with_description("Command 1")
.with_flag(
Flag::with_name("flag1")
.with_alias("f1")
.with_description("Flag 1")
)
.with_param(
Param::with_name("param1")
.with_description("Param 1")
)
.with_subcommand(
Command::with_name("bar")
.with_description("Command 1:1")
.with_flag(
Flag::with_name("flag2")
.with_alias("f2")
.with_description("Flag 2")
)
.with_resolver(|_intent, &mut _context| Ok(2))
)
.with_resolver(|_intent, &mut _context| Ok(3))
.with_handler(|_error, _intent, &mut _context| Ok(4))
.run(
&mut Context::default(),
)
{
Ok(code) => {
println!("Success: {:?}", code);
std::process::exit(0);
},
Err(error) => {
println!("Error: {:?}", error);
std::process::exit(1);
},
}
}
You can use your own custom context object as well:
...
.run<MyContext>(
MyContext::default()
)
