Changelog

All notable changes to this project are documented in this file.

[2.0.1] - 2026-05-31

Added

  • README — v2 API docs (safe lookup, path API, throwing loads/dumps, typed accessors, lua_val factories); link to CHANGELOG.md; static analysis usage.
  • Static analysis — .clang-tidy, cmake/StaticAnalysis.cmake, cppcheck-suppressions.txt, and Ubuntu CI job (cppcheck + clang-tidy).
  • Tests — expanded smallfolk_tests / smallfolk_schema_tests coverage; fixed gvx/Lua Smallfolk wire interop fixtures in test_lua_smallfolk_interop_wires().

Fixed

  • Non-finite wire on glibc/libstdc++ — NaN/Inf values serialize as gvx tokens (N/Q/I/i) instead of libc nan/inf text that broke round-trip on Linux/macOS; parse nan literals and map N/Q via std::nan.
  • Schema depth-limit test — avoid dangling CompiledSchema reference to a temporary nested schema (validation spuriously passed on GCC).

Changed

  • Restored pre-v2 API and serializer comments in smallfolk.h / smallfolk.cpp.
  • README build instructions: fix SMALLFOLK_BUILD_TESTS cmake typo.

[2.0.0] - 2026-05-31

Added

  • CMake library target (smallfolk_cpp::smallfolk), install/export, CTest, benchmark, and multi-platform CI (Linux, macOS, Windows).
  • ASSUMPTIONS.md — documented copy semantics, comparison, limits, threading, and security expectations.
  • LoadLimits — configurable deserialization bounds (max_input_size, max_string_length, max_nesting_depth, max_value_count, max_table_entries, require_consumed_input, reject_non_finite_numbers).
  • LuaVal::untrusted_load_limits() — tighter defaults for untrusted input.
  • Thread-safe LuaVal::get_load_limits() / set_load_limits() (prefer per-call limits in servers).
  • Safe lookup API — try_get, find, at, has (no auto-vivification).
  • Path API — try_get_path, get_path, at_path, has_path, set_path, erase_path (variadic and initializer_list overloads).
  • Typed accessors — try_as_number, try_as_string, try_as_bool.
  • Throwing API — loads_or_throw, dumps_or_throw.
  • Aliases — merge/mrg, erase/rem.
  • smallfolk_convert.h / namespace lua_val — STL-friendly factories (map, array, etc.).
  • Schema validation (smallfolk_schema.h) — Schema, CompiledSchema, validate, loads_validated, ValidateLimits.
  • namespace schema presets — number_range, string_length, string_enum, array_of, map_of, one_of, value(), and more.
  • Interactive demo restored as examples/demo.cpp (smallfolk_demo CTest target) with Release-safe DEMO_CHECK checks.

Changed

  • Parser/serializer fixes (non-finite numbers, quoted strings, whitespace, trailing input rejection).
  • schema::array_of / map_of / one_of / string_enum return self-contained owned schemas (no global factory deque).
  • Schema factories take Schema by value where appropriate (move-friendly).

Removed

  • schema::one_of(Schema const * const *, size_t) — use std::vector<Schema>, std::initializer_list<Schema>, or braced alternatives instead.

Notes

  • Table @ circular references remain unsupported (deep copy on assign; @ ignored on load).
  • operator== for tables compares internal pointer identity, not structural equality.
  • LuaVal mutation is not thread-safe — treat parsed values as immutable when shared across threads.
  • See ASSUMPTIONS.md for full behavioral contract.

[1.0.0] - 2022-10-13

Initial public release: LuaVal type, Smallfolk wire-format serialize/deserialize, header + single .cpp integration.
