[neko-function/1.0.7] New Recipe Submission

Recipe Information

• Recipe name: neko-function
• Version: 1.0.7
• Homepage: https://github.com/moehoshio/NekoFunction
• License: MIT OR Apache-2.0
• Description: A comprehensive modern C++ utility library that provides practical functions for common programming tasks

Key Features

• Utilities Module (header-only): String processing, time handling (ISO 8601), Base64 encoding/decoding, random generation, validation, operators (pipe, fallback, optional chaining), memory and lambda utilities
• Hash Module (requires OpenSSL): Cryptographic hash functions (MD5, SHA1, SHA256, SHA512)
• UUID Module (v4 always available, v3 requires OpenSSL): UUID generation
• Archive Management (requires minizip-ng): ZIP archive creation/extraction with encryption support
• File Type Detection (header-only): Magic number and extension-based file type detection
• C++20 Module Support: Optional module interface

Recipe Options

The recipe provides the following options:

• enable_hash (default: False): Enable hash support (adds OpenSSL dependency)
• enable_archive (default: False): Enable archive support (adds minizip-ng dependency)
• enable_module (default: False): Enable C++20 module support

Package Type

The recipe intelligently sets the package type:

• header-library: When both enable_hash and enable_archive are False (default)
• library: When either enable_hash or enable_archive is True

Dependencies

Required

• NekoSchema: Currently auto-fetched via CMake FetchContent (will be added as Conan dependency once available in ConanCenter)

Conditional (based on options)

• openssl (>=3.0): Required when enable_hash=True
• minizip-ng (>=4.0): Required when enable_archive=True

Testing

This recipe has been extensively tested and verified through automated integration package management testing. The testing methodology includes:

1. Local Installation: Recipe is installed via Conan in local mode (conan create)
2. Minimal Build Unit: A minimal compilation unit (tests/conan/test.cpp) is created and built
3. Functional Testing: The test executable validates core functionality

Test Platforms

• Windows (MSVC)
• Linux (GCC/Clang)
• macOS (AppleClang)

The testing ensures that:

• Recipe builds successfully with Conan
• CMake find_package(NekoFunction) succeeds
• Neko::Function target is properly exported and linkable
• All enabled options function correctly
• Proper header-only vs library packaging based on options

Additional Notes

• The recipe uses CMake FetchContent to automatically fetch NekoSchema until it becomes available in ConanCenter
• Header-only components work with minimal dependencies
• Feature-dependent components are properly gated by options
• The library provides both traditional headers and optional C++20 module support
• Proper target name mapping for minizip-ng is configured
• All tests pass in CI/CD environments
