Major changes

feat(store,world): more granularity for onchain hooks (#1399) (@latticexyz/store, @latticexyz/world)

• The onSetRecord hook is split into onBeforeSetRecord and onAfterSetRecord and the onDeleteRecord hook is split into onBeforeDeleteRecord and onAfterDeleteRecord. The purpose of this change is to allow more fine-grained control over the point in the lifecycle at which hooks are executed.

  The previous hooks were executed before modifying data, so they can be replaced with the respective onBefore hooks.

  - function onSetRecord(
  + function onBeforeSetRecord(
      bytes32 table,
      bytes32[] memory key,
      bytes memory data,
      Schema valueSchema
    ) public;
  
  - function onDeleteRecord(
  + function onBeforeDeleteRecord(
      bytes32 table,
      bytes32[] memory key,
      Schema valueSchema
    ) public;
  

• It is now possible to specify which methods of a hook contract should be called when registering a hook. The purpose of this change is to save gas by avoiding to call no-op hook methods.

  function registerStoreHook(
    bytes32 tableId,
  - IStoreHook hookAddress
  + IStoreHook hookAddress,
  + uint8 enabledHooksBitmap
  ) public;
  
  function registerSystemHook(
    bytes32 systemId,
  - ISystemHook hookAddress
  + ISystemHook hookAddress,
  + uint8 enabledHooksBitmap
  ) public;
  

  There are StoreHookLib and SystemHookLib with helper functions to encode the bitmap of enabled hooks.

  import { StoreHookLib } from "@latticexyz/store/src/StoreHook.sol";
  
  uint8 storeHookBitmap = StoreBookLib.encodeBitmap({
    onBeforeSetRecord: true,
    onAfterSetRecord: true,
    onBeforeSetField: true,
    onAfterSetField: true,
    onBeforeDeleteRecord: true,
    onAfterDeleteRecord: true
  });
  

  import { SystemHookLib } from "@latticexyz/world/src/SystemHook.sol";
  
  uint8 systemHookBitmap = SystemHookLib.encodeBitmap({
    onBeforeCallSystem: true,
    onAfterCallSystem: true
  });
  

• The onSetRecord hook call for emitEphemeralRecord has been removed to save gas and to more clearly distinguish ephemeral tables as offchain tables.

Patch changes

fix(abi-ts): remove cwd join (#1418) (@latticexyz/abi-ts)

Allow callFrom with the own address as delegator without requiring an explicit delegation

Version 2.0.0-next.6

Major changes

style(gas-report): rename mud-gas-report to gas-report (#1410) (@latticexyz/gas-report)

Renames mud-gas-report binary to gas-report, since it's no longer MUD specific.

Minor changes

docs: rework abi-ts changesets (#1413) (@latticexyz/abi-ts, @latticexyz/cli)

Added a new @latticexyz/abi-ts package to generate TS type declaration files (.d.ts) for each ABI JSON file.

This allows you to import your JSON ABI and use it directly with libraries like viem and abitype.

pnpm add @latticexyz/abi-ts
pnpm abi-ts

By default, abi-ts looks for files with the glob **/*.abi.json, but you can customize this glob with the --input argument, e.g.

pnpm abi-ts --input 'abi/IWorld.sol/IWorld.abi.json'

docs: rework abi-ts changesets (#1413) (create-mud)

We now use @latticexyz/abi-ts to generate TS type declaration files (.d.ts) for each ABI JSON file. This replaces our usage TypeChain everywhere.

If you have a MUD project created from an older template, you can replace TypeChain with abi-ts by first updating your contracts' package.json:

-"build": "pnpm run build:mud && pnpm run build:abi && pnpm run build:typechain",
+"build": "pnpm run build:mud && pnpm run build:abi && pnpm run build:abi-ts",
-"build:abi": "forge clean && forge build",
+"build:abi": "rimraf abi && forge build --extra-output-files abi --out abi --skip test script MudTest.sol",
+"build:abi-ts": "mud abi-ts --input 'abi/IWorld.sol/IWorld.abi.json' && prettier --write '**/*.abi.json.d.ts'",
 "build:mud": "mud tablegen && mud worldgen",
-"build:typechain": "rimraf types && typechain --target=ethers-v5 out/IWorld.sol/IWorld.json",

And update your client's setupNetwork.ts with:

-import { IWorld__factory } from "contracts/types/ethers-contracts/factories/IWorld__factory";
+import IWorldAbi from "contracts/abi/IWorld.sol/IWorld.abi.json";

 const worldContract = createContract({
   address: networkConfig.worldAddress as Hex,
-  abi: IWorld__factory.abi,
+  abi: IWorldAbi,

docs: rework abi-ts changesets (#1413) (@latticexyz/store, @latticexyz/world)

We now use @latticexyz/abi-ts to generate TS type declaration files (.d.ts) for each ABI JSON file. This replaces our usage TypeChain everywhere.

If you previously relied on TypeChain types from @latticexyz/store or @latticexyz/world, you will either need to migrate to viem or abitype using ABI JSON imports or generate TypeChain types from our exported ABI JSON files.

import { getContract } from "viem";
import IStoreAbi from "@latticexyz/store/abi/IStore.sol/IStore.abi.json";

const storeContract = getContract({
  abi: IStoreAbi,
  ...
});

await storeContract.write.setRecord(...);
