So while we require at least 3 arguments, it makes sense to only ask for 2. --- diff --git a/src/args.rs b/src/args.rs index a9d1729..b6ae379 100644 --- a/src/args.rs +++ b/src/args.rs @@ -10,7 +10,7 @@ use std::str::FromStr; pub(crate) fn parse_startup_args() -> Result { if env::args().len() < 3 { - println!("ldk-tutorial-node requires 3 arguments: `cargo run [:@]: ldk_storage_directory_path [] [bitcoin-network] [announced-node-name announced-listen-addr*]`"); + println!("ldk-tutorial-node requires at least 2 arguments: `cargo run [:@]: ldk_storage_directory_path [] [bitcoin-network] [announced-node-name announced-listen-addr*]`"); return Err(()); } let bitcoind_rpc_info = env::args().skip(1).next().unwrap();
