Compiling Move Scripts

How can I compile Move Scripts?

Move scripts can be compiled with the already existing Endless Move compiler in the Endless CLI. For more on how to install and use the Endless CLI with Move contracts, go to the Working With Move Contracts page.

Once you have the Endless CLI installed, you can compile a script by running the following command from within the script package:

endless move compile

There will then be compiled bytecode files under build/ with the same name as the function in Move.

For example this script in package transfer_half, would compile to build/transfer_half/bytecode_scripts/transfer_half.mv

script {
  use std::signer;
  use endless_framework::coin;
  use endless_framework::endless_account;

  fun transfer_half<Coin>(caller: &signer, receiver_address: address) {
    // Retrieve the balance of the caller
    let caller_address: address = signer::address_of(caller);
    let balance: u64 = coin::balance<Coin>(caller_address);

    // Send half to the receiver
    let half = balance / 2;
    endless_account::transfer_coins<Coin>(caller, receiver_address, half);
  }
}

Additionally, there is a convenience function for a package with exactly one script with the below command:

endless move compile-script

Providing output like below returning the exact location of the script and a hash for convenience
