NIST Misses 2024 Deadline to Clear NVD Backlog
NIST has failed to meet its self-imposed deadline of clearing the NVD's backlog by the end of the fiscal year. Meanwhile, CVE's awaiting analysis have increased by 33% since June.
@appliedblockchain/trufflib
Advanced tools
This module has our shared solidity libraries (such as error handling and signature verification)
It also contains helpers which allow us to easily test for the correct events to be emitted and more (in the future)
npm install --save @appliedblockchain/trufflib
We currently only have test helpers
// require test helpers in your truffle test file
const Helpers = require('@appliedblockchain/trufflib/helpers/Test')
// then, in a truffle test
await Helpers.expectErrorEvent(contract.doSomethingBroken(), 'This doesnt work.')
See truffle-examples for some more usage examples.
Truffle supports importing contracts (or libraries) from node modules. Truffle npm package documentation
import "@appliedblockchain/trufflib/libraries/Err.sol";
// then in a function, you can use the Err library
Err.stopUnless(msg.sender == creator, 'Only the creator can set the message.');
Again, see truffle-examples for some more usage examples.
