Expand description
Import user registered custom command.
fn my_cmd(env: &mut CmdEnv) -> CmdResult {
let msg = format!("msg from foo(), args: {:?}", env.get_args());
writeln!(env.stderr(), "{msg}")?;
writeln!(env.stdout(), "bar")
}
use_custom_cmd!(my_cmd);
run_cmd!(my_cmd)?;
Here we import the previous defined my_cmd
command, so we can run it like a normal command.
