v1.1.1

• Update dependencies to the latest version.

v1.1.0

• Support for constants in code tables.
• Use correct code line for error messages in code tables for built-ins.
• Switch to Foundry's print function for trace logs.
• Allow using --target-address to specify the contract address during a test.
• Disable base fee check for tests.
• Allow uneven bytes for code tables e.g. 0x1 is valid and results in 0x01 bytecode.
• Introduce new lexer token type Bytes, as not all hex should be parsed to bytes32.
  • For constants in code tables, the bytes are copied as defined with e.g. leading zeros.
  • For all other cases, leading zeros are removed and the smallest push operation is used.
• New built-in function __LEFTPAD to a pad a hex input or a function result in a code table to the left in 32 bytes.
  • The function can only be used in a code table.
  • Example: __LEFTPAD(0x123) -> 0000000000000000000000000000000000000000000000000000000000000123
• Allow to pass a constant as a parameter to __RIGHTPAD or __LEFTPAD.
  • Example: __RIGHTPAD([CONST])
• Allow to use built-in functions in constant assignment.
  • Example: #define constant FUNC_TEST = __FUNC_SIG("test(uint256)")
  • This solves the issue to define functions with the same name but different arguments.

v1.0.8

• Support built-in function calls in code table (#define table) body.
  • Supported are __BYTES, __FUNC_SIG, and __RIGHTPAD.

v1.0.7

• Add built-in macros for converting a string to bytes and push it to the stack.
  • __BYTES("hello") -> PUSH5 0x68656c6c6f
  • This can also be used here: __RIGHTPAD(__BYTES("hello")).

v1.0.6

• Allow to use --debug for reverting contracts.
• Refactored parsing for ABI and build-in argument.
  • This is the first step to push more steps into the lexing phase.
• Extend parsing to allow __FUNC_SIG inside of __RIGHTPAD.
  • Example: __RIGHTPAD(__FUNC_SIG('transfer(address,uint256)')).

v1.0.5

• Use foundry's debugger for --debug flag.

v1.0.4

• Rewrite the Huff test module to use anvil and forge features from foundry to fork the mainnet.
  • This is experimental, and there will be some breaking changes.
• Allow printing logs with -vvv and call traces for tests with -vvvv.
• Add forge EVM feature flags for testing.
  • Known issues: The CLI reports more features than are actually available.
• Breaking: Remove the Huff cheat code for logging.
  • The foundry console.log should now be used.
• Breaking: Remove logs from the test JSON output for now.
• Fix error reporting for invalid literals during lexing in the test command.
• Add Cancun as an EVM version and make it the default.
• Breaking: The -f flag for formatting the output is now replaced with the fork URL. Please use --format instead.
• Tokio is now used for the test runner to be able to use the db backend from foundry.

v1.0.3

• Remove huff-examples submodule
• Fix invalid error mapping for import with unmatched jump labels
• Print unmatched jump labels

v1.0.2

• Use latest stable Rust version 1.84
• Report error for invalid hex literals 0x0x
• Improve lexer performance by 1-2% by removing unnecessary cloning
• Allow to use same name for test and macro or fn

v1.0.1

• Validate that a constant hex literal is not longer than 32 bytes
• New flatten source algo to determine spans
• Fix all errors related to invalid source code mapping
• Limit label duplicate check to containing macro and file
