MicroHammer v2.0.1

This release hardens public API input validation and removes integer-truncation bugs that could cause silent misbehavior in release builds.

Added

• HAMMER_ASSERT macro in internal.h: unconditional abort for programmer errors that survives -DNDEBUG, unlike assert()

Changed

• h_assert_type macro updated to use HAMMER_ASSERT, aborting on type mismatch in all builds
• test_token_len_assert updated to verify that tokens longer than 255 bytes are now accepted and parse correctly end-to-end
• CI pipeline extended with ruff linting of Python and SCons files, gating the build-deb step

Fixed

• HToken.len and bits_env.length widened from uint8_t to size_t, resolving silent integer truncation for tokens and bit counts above 255. h_bits(264, false) no longer silently behaves as h_bits(8, false) (#3)
• assert()-based programmer-error guards replaced with HAMMER_ASSERT across bitwriter.c, glue.c, glue.h, datastructures.c; runtime boundary conditions retain explicit safe returns (#6)

MicroHammer v2.0.0

This release reintroduces multi-language bindings, bringing Python, Java, and C++ support back to the library alongside testing and build infrastructure improvements.

Added

• Python bindings via SWIG with a setup.py-based build and unittest smoke tests
• Java/JNI bindings via SWIG with a hammer.jar package and standalone smoke tests
• Header-only C++ wrapper (hammer.hpp) with gtest-based tests and assertion helpers (hammer_test.hpp)
• tools/test_reporter.py to label per-binding test output and aggregate pass/fail counts into a final summary table
• scons bindings=<python,java,cpp> option to build and test individual language bindings
• Per-binding installpython, installjava, and installcpp SCons targets

Changed

• scons test now runs core tests followed by any enabled binding tests, with a combined results summary
• CI pipeline extended with dependency installation and a dedicated binding test step
• Updated org/package namespace from upstandinghackers to riversideresearch throughout

Fixed

• ParseResult made move-only to prevent double-free on copy
• Python SWIG typemap for void*[] now frees the allocated parser array after each call
• Python SWIG uint8_t typemap validates single-byte length before dereferencing

MicroHammer v1.1.2

This release is a patch fix a bug with token length truncation.

Changed

• Document change to prevent confusion over magic number.
• Add test to check that truncation bug is not possible.

Fixed

• Fix token length truncation bug from Issue #3

MicroHammer v1.1.1

This release is a patch update addressing a build bug, improving install/uninstall support, and adding a CI pipeline.

Added

• scons uninstall target to remove all files placed by scons install
• variant=microhammer field to libhammer.pc for identifying the installed variant via pkg-config
• GitHub Actions CI pipeline for formatting checks, tests, and .deb builds on pull requests

Changed

• Installed .so files no longer carry a version suffix (libhammer.so instead of libhammer.so.1.1.x)
• Improved h_in and h_not_in documentation to clarify cursor and byte consumption behavior

Fixed

• Crashing scons test caused by misaligned backend names array in benchmark.c after non-packrat backends were pruned

MicroHammer v1.1.0

This release focuses on testing, coverage, and project structure cleanup in order to lay a solid foundation for future development.

Added

• Comprehensive test coverage for parsers, backends, allocators, and the core library
• Code coverage support using lcov / gcov
• New --coverage build flag for generating coverage reports
• Test coverage documentation in DEVELOPMENT.md

Changed

• Major testing infrastructure overhaul
• Reorganized test suite: tests moved from src/ to tests/
• Parser tests split into focused files under tests/parsers/
• Build artifacts are now generated in the build/ directory

Removed

• Removed deprecated params backend

Quality

• Achieved ~100% line coverage for parsers and top-level source files

MicroHammer v1.0.0

This is the first release of MicroHammer, a slimmed-down version of the Hammer parsing library.

This version removes:

• non-packrat backends
• all language bindings
• Windows / macOS support
• Makefile build system
• other extra or non-essential files

The goal is to provide a lightweight, Linux-focused version of Hammer with a minimal, clean codebase.

Added / Improved

• improved documentation (consistent Doxygen comments for public API)
• code style consistency (linting + formatting)
• Debian packaging / build support
