diff2test v0.1.1

diff2test v0.1.1

A polished release of diff2test, a conservative zero-runtime-dependency C++20 test-impact analysis CLI for CMake/CTest projects.

Highlights

• Convention-over-configuration CLI:
  diff2test analyze .
• Changed paths are read from stdin by default.
• Optional Git composition:
  git diff --name-only HEAD~1 | diff2test analyze .
• Git is not a runtime dependency; diff2test only consumes newline-delimited changed paths.
• Conventional metadata defaults under <project-root>/build.
• --build convenience alias for --build-root.
• Fully explicit legacy CLI remains supported.
• Conservative safety behavior is unchanged:
  • 0 — SUBSET_SELECTED
  • 10 — FULL_SUITE_SELECTED
  • 11 — FULL_SUITE_REQUIRED
• Single-file runtime implementation.
• Zero third-party runtime dependencies.
• No runtime subprocess execution.
• Deterministic output and same-runner reproducible Release builds.
• Public CI covers the real CMake/CTest fixture, fallback behavior, sanitizers, subprocess audit, and reproducibility.

Supported boundary

The verified MVP targets Linux, C++20, GCC/Clang Make-style dependency files, CMake File API codemodel v2, and CTest json-v1.

Unsupported or incomplete evidence widens conservatively rather than guessing.
