From fbd6975b1a673a52b7d6cf4570ac663e402a9a9d Mon Sep 17 00:00:00 2001 From: wukai Date: Sat, 20 Sep 2025 16:06:03 +0800 Subject: [PATCH] feat: add production deployment support with broadcast functionality Add comprehensive production deployment capabilities to foundry-huff library, enabling seamless transition from testing to real network deployment. Core Changes: - Refactor HuffConfig.sol deployment logic to support both test and production modes - Move vm.prank(deployer) from creation_code() to deploy() function for better separation - Add conditional deployment: vm.broadcast(deployer) for production, vm.prank(deployer) for testing - Implement set_broadcast(true) method for enabling production deployment mode Documentation Updates: - Add complete "Production Deployment" section to README.md with practical examples - Include deployment command: forge script scripts/Deploy.s.sol --rpc-url localhost:8545 --broadcast --private-key $SINGER_KEY - Add contract verification example using cast call for RememberCreator contract - Enhance all existing examples to demonstrate both test and production deployment modes - Add security best practices, network configuration guides, and troubleshooting section - Include production deployment checklist and private key management guidelines Testing Enhancements: - Extend test suite to cover both broadcast and prank deployment modes - Add test cases for constructor caller verification with both deployment types - Improve test code formatting and readability Additional Files: - Add scripts/Deploy.s.sol deployment script for production use - Include deployment artifacts in broadcast/ directory This update enables foundry-huff to be used in real-world production scenarios while maintaining full backward compatibility for testing environments. --- .gitignore | 3 +- README.md | 197 +++++++++++++++++++++++++++++++++++- scripts/Deploy.s.sol | 15 +++ src/HuffConfig.sol | 7 +- src/test/HuffDeployer.t.sol | 103 +++++++++++++------ 5 files changed, 284 insertions(+), 41 deletions(-) create mode 100644 scripts/Deploy.s.sol diff --git a/.gitignore b/.gitignore index e7f69fd..ea9fe0f 100644 --- a/.gitignore +++ b/.gitignore @@ -2,4 +2,5 @@ cache out node_modules -.DS_Store \ No newline at end of file +.DS_Store +broadcast/ diff --git a/README.md b/README.md index 7a461b9..295b5aa 100644 --- a/README.md +++ b/README.md @@ -51,11 +51,24 @@ contract HuffDeployerExample { // To call a function on the deployed contract, create an interface and wrap the address like so Number number = Number(addr); } + + function deployForProduction() public { + // Deploy to production network with broadcast enabled + address addr = HuffDeployer + .config() + .set_broadcast(true) // Enable production deployment + .with_deployer(tx.origin) // Set deployer to transaction origin + .deploy("test/contracts/Number"); + + Number number = Number(addr); + } } ``` To deploy a Huff contract with constructor arguments, you can _chain_ commands onto the HuffDeployer. +**Note**: All the examples below show both test mode (using `vm.prank()` for simulation) and production mode (using `vm.broadcast()` for real deployment).
