Combine py::enumerate and py::const_enumerate

Full Changelog: 1.5...1.5.1

py2cpp v1.5.1 Release Notes 🎉🚀

Released on November 28, 2025

We're excited to ship py2cpp 1.5.1 – a feature-packed release focused on Python fidelity, modern C++ compatibility, and smoother development experience!

New Features & Enhancements ✨

• Full support for enumerate() on const containers
  You can now safely write for i, v in py::const_enumerate(container) – perfect for range-based for loops without copying!
  Also added py::enumerate() wrapper for non-const cases.

• New const_enumerate() utility (with detailed docs)
  Clean, safe, and zero-overhead enumeration over const iterables and ranges.

• Improved dict and list methods

  • dict::contains(key) now properly noexcept and const-correct
  • Added modern items() → returns view of (key, value) pairs
  • len() now works naturally on py2cpp containers

• Better range support
  Full C++20-compatible range semantics with proper begin()/end() and const iterators.

• Added GEMINI CLI command 🌟
  New py2cpp gemini subcommand for AI-assisted code conversion (experimental but awesome!)

Bug Fixes & Build Improvements 🛠️

• Fixed macOS build by adding -DCMAKE_POLICY_VERSION_MINIMUM=3.5 (Who-dev)
• Fixed sign-conversion warnings on Oct 1 → cleaner builds on modern compilers
• Updated CMake workflows to latest standards
• Bumped project version to 1.5.1 and updated CMakeLists.txt accordingly

Under the Hood 🔧

• Merged enumerate() and const_enumerate() implementations for consistency
• Lots of noexcept additions and const-correctness fixes across containers
• Improved template deduction guides
• Better iterator traits and SFINAE handling

CI/CD

• Added proper doctest and boost.ut test packages
• Modernized xmake.lua config
• Cleaner GitHub Actions workflows

Big thanks to @luk036 for driving this release at warp speed! ⚡

1.5

Full Changelog: 1.4.11...1.5

Release Notes: py2cpp v1.5

Overview

This release introduces several enhancements to the py2cpp library, a header-only C++ library designed to bring Python-like features to modern C++. Key improvements include expanded unit test coverage, code optimizations, and updates to build configurations.

🚀 New Features & Improvements

1. Enhanced Unit Test Coverage

• Added comprehensive unit tests for Boost Graph adaptors (test_nx2bg1.cpp):
  • GrAdaptor for graph operations
  • VertexView and EdgeView for graph traversal
  • AtlasView for neighbor iteration
• Added tests for Python-like data structures:
  • py::dict methods including contains, get, items, copy, and len
  • py::enumerate and py::const_enumerate for iterable indexing
• Extended tests for Fraction class in fractions.hpp:
  • Arithmetic operations (+, -, *, /)
  • Comparison operators (<, <=, >, >=, ==, !=)
  • In-place operations (+=, -=, *=, /=)

2. Code Optimizations

• Performed code optimizations via Gemini CLI
• Applied fix-format to ensure consistent code style

3. Build System Updates

• Upgraded C++ standard from C++14 to C++17
• Added Boost support in XMake configuration:
  • Included boost package dependency
  • Added Boost-specific test files to the build
• Improved compiler flag handling for Linux and Windows platforms

🛠️ Development Workflow Improvements

• Updated CMakeLists.txt to use C++17 standard
• Enhanced XMake configuration for better cross-platform compatibility
• Added [[maybe_unused]] attribute to silence compiler warnings in range-based loops

✅ Testing

• All new tests pass successfully using the doctest framework
• CI pipeline now includes Boost-based tests via XMake

📦 Dependencies

• Added explicit dependency on Boost library for graph-related features
• Maintained compatibility with fmt and doctest

🔧 Known Issues

• None reported in this release

📄 Documentation

• Documentation can still be generated via Doxygen using the provided CMake targets
