Gas Report

Measure and report gas usage within forge tests

Add some reports to your forge tests

import { Test } from "forge-std/Test.sol";
import { GasReporter } from "@latticexyz/gas-report/src/GasReporter.sol";

contract ExampleTest is Test, GasReporter {
  function testGas() public {
    startGasReport("description of behavior to measure gas for");
    // do something here
    endGasReport();
  }
}

Then use the cli command to run tests and save the report:

pnpm gas-report --save gas-report.json

Or, if you have your own test command, you can pipe the output to gas-report --stdin:

GAS_REPORTER_ENABLED=true forge test -vvv --isolate | pnpm gas-report --stdin

Run pnpm gas-report --help for more details.

Changelog

Version 2.2.9

Release date: Wed Sep 25 2024

Patch changes

feat(explorer): dozer integration (#3185) (@latticexyz/explorer)

Exploring worlds on Redstone and Garnet chains will now retrieve data from the hosted SQL indexer.

feat(explorer): local indexer inside explorer (#3229) (@latticexyz/explorer, create-mud)

Explorer now automatically starts a local indexer when using Anvil as the target chain.

If you previously had an indexer entry in your mprocs.yaml file, it can now be removed.

-  indexer:
-    cwd: packages/contracts
-    shell: shx rm -rf $SQLITE_FILENAME && pnpm sqlite-indexer
-    env:
-      DEBUG: mud:*
-      RPC_HTTP_URL: "http://127.0.0.1:8545"
-      FOLLOW_BLOCK_TAG: "latest"
-      SQLITE_FILENAME: "indexer.db"

feat(explorer): move filter state to url (#3225) (@latticexyz/explorer)

Table filters are now included as part of the URL. This enables deep links and improves navigating between pages without losing search state.

refactor(cli): adjust deploy order (#3222) (@latticexyz/cli)

Adjusted deploy order so that the world deploy happens before everything else to avoid spending gas on system contract deploys, etc. if a world cannot be created first.
