Describe the bug

I have some libraries with convenience functions that I like to use in my scripts.

For example, a readableNum library that lets me log numbers in decimal format (for easier debugging), or a stdJsonDB library that lets me serialize/write data to a file in a single call. Despite me using these utilities outside the the bounds of vm.startBroadcast(privKey)and vm.stopBroadcast(), forge script still manages to include their deployments among the broadcasted transactions.

For an example:

        // squeeth contract payoff provider
        try stdJsonDB.getAddr("ContractPayoffProvider_Squeeth", deployments) returns (address deployedAddr) {
                 // some code
        } catch {
                 // some code
            vm.startBroadcast(deployerPrivateKey);

            squeeth = new Squeeth();                                      // THIS

            vm.stopBroadcast();
                 // some code
        }

        try stdJsonDB.getAddr(deploymentName, deployments) returns (address productAddress) {
                 // some code
        } catch {
                 // some code
            vm.startBroadcast(deployerPrivateKey);

            (bool success, bytes memory data) = address(controller).call(                                 
                abi.encodeCall(IController.createProduct, (coordinatorID, productInfo))
            );                                                            // AND THIS

            vm.stopBroadcast();
                  // some code
        }

I expect this script to broadcast only the operations I marked but forge script also cues up and deploys the stdJsonDB library.

Here's a simpler example. When i run this script it deploys SomeLibrary - why?

// SPDX-License-Identifier: Unlicense
pragma solidity ^0.8.17;

import "forge-std/Script.sol";

contract ExtraBroadcastTest is Script {
    function run() external {
        SomeLibrary.reflect(5);

        vm.startBroadcast(vm.envUint("PRIVATE_KEY"));
        (bool success,) = address(0).call{value: 0 ether}("");
        vm.stopBroadcast();

        require(success, "Call failed.");

    }
}

library SomeLibrary {
    function reflect(uint number) external pure returns (uint) {
        return number;
    }
}

[Skelectric]

If i change SomeLibrary into an abstract contract and make the script inherit from it, this doesn't happen.

So libraries and forge script don't mix?

This is unfortunate as there are things I can't do with abstract contracts that I can do with libraries. For example, the try-catch pattern.

I am getting the same issue! Thanks for reporting this.

I have also gotten this issue recently. It looks like it only affects external libraries, as internal libraries are inlined.
