**ConsoleHelpers.h**: Complete rewrite with proper C++ console I/O, debug macros, and string handling utilities - **FileHelpers.h**: Comprehensive file operations using std::filesystem and modern C++ streams with type-safe template functions - **TemporaryFile.h**: RAII-compliant temporary file class with proper move semantics and automatic cleanup - **TemporaryFiles.h**: Thread-safe temporary file management with mutex synchronization - **StreamExtensions.h**: Template-based stream I/O for binary data with type safety constraints - **ConsoleCancellation.h**: Signal-based cancellation handling using SIGINT with atomic operations ### Key Features: - Modern C++20 standards with concepts and constraints - Thread-safe operations using std::mutex - RAII patterns for automatic resource management - Type-safe template functions with static_assert checks - Comprehensive error handling with exceptions - CMake build system with Google Test integration - Cross-platform compatibility using std::filesystem ### Tests and Build: - Updated test files to use Google Test framework - Added CMakeLists.txt with proper dependency management - Created comprehensive test suite covering all major functionality - Added Platform.IO.h main header for easy inclusion 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- cpp/CMakeLists.txt | 106 ++++++ .../Program.cpp | 19 +- cpp/Platform.IO.Tests/FileHelpersTests.cpp | 100 +++++- cpp/Platform.IO.Tests/TemporaryFileTests.cpp | 57 ++-- cpp/Platform.IO/ConsoleCancellation.h | 145 ++++++-- cpp/Platform.IO/ConsoleHelpers.h | 140 +++++++- cpp/Platform.IO/FileHelpers.h | 309 ++++++++++++++---- cpp/Platform.IO/Platform.IO.h | 17 + cpp/Platform.IO/StreamExtensions.h | 154 +++++++-- cpp/Platform.IO/TemporaryFile.h | 106 +++++- cpp/Platform.IO/TemporaryFiles.h | 97 ++++-- cpp/Platform.IOConfig.cmake.in | 9 + cpp/test_all.cpp | 32 ++ 13 files changed, 1101 insertions(+), 190 deletions(-) create mode 100644 cpp/CMakeLists.txt create mode 100644 cpp/Platform.IO/Platform.IO.h create mode 100644 cpp/Platform.IOConfig.cmake.in create mode 100644 cpp/test_all.cpp diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt new file mode 100644 index 0000000..f739fe9 --- /dev/null +++ b/cpp/CMakeLists.txt @@ -0,0 +1,106 @@ +cmake_minimum_required(VERSION 3.15) + +# Set the project name and version +project(Platform.IO VERSION 1.0.0 LANGUAGES CXX) + +# Set C++ standard +set(CMAKE_CXX_STANDARD 20) +set(CMAKE_CXX_STANDARD_REQUIRED ON) +set(CMAKE_CXX_EXTENSIONS OFF) + +# Platform.IO library +add_library(Platform.IO INTERFACE) + +# Header files +target_include_directories(Platform.IO INTERFACE + $ + $ +) + +# Target compile features +target_compile_features(Platform.IO INTERFACE cxx_std_20) + +# Find required system libraries +find_package(Threads REQUIRED) +target_link_libraries(Platform.IO INTERFACE Threads::Threads) + +# Enable testing +option(BUILD_TESTS "Build tests" ON) +if(BUILD_TESTS) + enable_testing() + + # Find Google Test + find_package(GTest QUIET) + if(NOT GTest_FOUND) + # Download and build Google Test + include(FetchContent) + FetchContent_Declare( + googletest + URL https://github.com/google/googletest/archive/release-1.12.1.zip + ) + # For Windows: Prevent overriding the parent project's compiler/linker settings + set(gtest_force_shared_crt ON CACHE BOOL "" FORCE) + FetchContent_MakeAvailable(googletest) + endif() + + # Test executable + add_executable(Platform.IO.Tests + Platform.IO.Tests/TemporaryFileTests.cpp + Platform.IO.Tests/FileHelpersTests.cpp + ) + + target_link_libraries(Platform.IO.Tests + Platform.IO + gtest_main + gtest + pthread + ) + + target_include_directories(Platform.IO.Tests PRIVATE + ${CMAKE_CURRENT_SOURCE_DIR} + ) + + # Register tests + include(GoogleTest) + gtest_discover_tests(Platform.IO.Tests) +endif() + +# Installation +install(DIRECTORY Platform.IO/ + DESTINATION include/Platform.IO + FILES_MATCHING PATTERN "*.h" +) + +install(TARGETS Platform.IO + EXPORT Platform.IOTargets + LIBRARY DESTINATION lib + ARCHIVE DESTINATION lib + RUNTIME DESTINATION bin + INCLUDES DESTINATION include +) + +install(EXPORT Platform.IOTargets + FILE Platform.IOTargets.cmake + NAMESPACE Platform:: + DESTINATION lib/cmake/Platform.IO +) + +# Create package config files +include(CMakePackageConfigHelpers) +write_basic_package_version_file( + Platform.IOConfigVersion.cmake + VERSION ${PACKAGE_VERSION} + COMPATIBILITY AnyNewerVersion +) + +configure_package_config_file( + ${CMAKE_CURRENT_SOURCE_DIR}/Platform.IOConfig.cmake.in + ${CMAKE_CURRENT_BINARY_DIR}/Platform.IOConfig.cmake + INSTALL_DESTINATION lib/cmake/Platform.IO +) + +install(FILES + ${CMAKE_CURRENT_BINARY_DIR}/Platform.IOConfig.cmake + ${CMAKE_CURRENT_BINARY_DIR}/Platform.IOConfigVersion.cmake + DESTINATION lib/cmake/Platform.IO +) \ No newline at end of file diff --git a/cpp/Platform.IO.Tests.TemporaryFileTest/Program.cpp b/cpp/Platform.IO.Tests.TemporaryFileTest/Program.cpp index bfab76e..a3ac14f 100644 --- a/cpp/Platform.IO.Tests.TemporaryFileTest/Program.cpp +++ b/cpp/Platform.IO.Tests.TemporaryFileTest/Program.cpp @@ -1,11 +1,14 @@ -namespace Platform::IO::Tests::TemporaryFileTest +#include +#include "../Platform.IO/TemporaryFile.h" + +using namespace Platform::IO; + +int main() { -
