From 46f95470f8e7ef4dc58562767e8cd8860f653b6e Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 27 Nov 2025 01:40:23 +0000 Subject: [PATCH 01/18] Modernize CMake configuration with best practices from cpp-best-practices This commit comprehensively refactors Ada's CMake build system to follow modern CMake best practices, inspired by cpp-best-practices/cmake_template. ## New Features ### CMakePresets.json - Added 16+ standardized build presets for common workflows - Presets for: dev, release, test, benchmark, sanitizers, coverage, CI - Ninja generator variants for faster builds - IDE integration (VS Code, CLion, Visual Studio 2019+) ### Developer Mode - New ADA_DEVELOPER_MODE option for comprehensive quality checks - Auto-enables: warnings as errors, development checks, static analyzers - Individual controls can still be overridden - Perfect for development and CI environments ### Modular CMake Files **cmake/ProjectOptions.cmake** - Centralized definition of all build options - Automatic developer mode configuration - Build type validation and defaults - Comprehensive feature summary display **cmake/CompilerWarnings.cmake** - Systematic compiler warning management - Functions: ada_set_project_warnings(), ada_set_sanitizer_flags(), ada_set_standard_settings() - Support for MSVC, GCC, Clang, AppleClang - Platform-specific optimizations (e.g., GCC AVX workaround) **cmake/StaticAnalyzers.cmake** - clang-tidy integration with .clang-tidy config - cppcheck integration with C++20 support - Functions: ada_enable_clang_tidy(), ada_enable_cppcheck(), ada_enable_static_analyzers() - Automatic tool detection and version reporting ## Refactored Files ### CMakeLists.txt - Reorganized with clear section headers - Integrated ProjectOptions.cmake - Better documentation and structure - Maintained backward compatibility ### cmake/ada-flags.cmake - Refactored to use new modular components - Removed duplicate option definitions (now in ProjectOptions.cmake) - Improved comments and organization - Enhanced coverage setup documentation ### src/CMakeLists.txt - Complete rewrite using new CMake functions - Cleaner, more maintainable code - Better documentation - Reduced from ~70 lines to ~80 lines of better-organized code ## Documentation ### docs/CMAKE_BEST_PRACTICES.md - Comprehensive guide to new CMake setup - Quick start with presets - Migration guide from old approach - IDE integration instructions - Troubleshooting section - Performance notes and best practices ## Benefits 1. **Standardization**: CMakePresets.json provides consistent builds 2. **Quality**: Developer mode enables comprehensive checks 3. **Maintainability**: Modular structure is easier to understand and extend 4. **IDE Support**: Modern IDEs auto-detect and use presets 5. **Performance**: Ninja presets for faster builds 6. **Documentation**: Clear structure and comprehensive docs 7. **Backward Compatibility**: Old build commands still work ## Testing All configurations tested and verified: - Basic library build (release preset) - Development build with quality checks (dev preset) - Testing configuration (test preset) - Library compiles successfully with GCC 13.3.0 - Developer mode properly enables all quality features ## Usage Examples ```bash # Development with all quality checks cmake --preset dev && cmake --build build/dev # Optimized release build cmake --preset release && cmake --build build/release # Benchmarks cmake --preset benchmark && cmake --build build/benchmark # With Ninja for faster builds cmake --preset dev-ninja && cmake --build build/dev-ninja ``` Inspired by: https://github.com/cpp-best-practices/cmake_template --- CMakeLists.txt | 41 +++-- CMakePresets.json | 251 ++++++++++++++++++++++++++++ cmake/CompilerWarnings.cmake | 246 +++++++++++++++++++++++++++ cmake/ProjectOptions.cmake | 182 ++++++++++++++++++++ cmake/StaticAnalyzers.cmake | 181 ++++++++++++++++++++ cmake/ada-flags.cmake | 125 ++++++++------ docs/CMAKE_BEST_PRACTICES.md | 311 +++++++++++++++++++++++++++++++++++ src/CMakeLists.txt | 110 +++++++------ 8 files changed, 1335 insertions(+), 112 deletions(-) create mode 100644 CMakePresets.json create mode 100644 cmake/CompilerWarnings.cmake create mode 100644 cmake/ProjectOptions.cmake create mode 100644 cmake/StaticAnalyzers.cmake create mode 100644 docs/CMAKE_BEST_PRACTICES.md diff --git a/CMakeLists.txt b/CMakeLists.txt index 1573f538c..0bbe002fc 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -9,22 +9,30 @@ set(ADA_LIB_VERSION "3.4.1" CACHE STRING "ada library version") set(ADA_LIB_SOVERSION "3" CACHE STRING "ada library soversion") include(GNUInstallDirs) -

Main Ubuntu CI - Now uses `--preset ci` with quality checks - Maintains matrix for shared libs and SIMDUTF variants - Cleaner, more maintainable configuration **ubuntu-sanitized.yml** - Address Sanitizer builds - Now uses `--preset sanitize-address` - Automatically configures all necessary sanitizer flags **ubuntu-undef.yml** - Undefined Behavior Sanitizer builds - Now uses `--preset sanitize-undefined` - Consistent configuration with local development **ubuntu-release.yml** - Release builds - Now uses `--preset release-ninja` - Optimized for production builds ## Documentation Updates **CLAUDE.md** - Complete rewrite for Claude Code users - Added prominent "Quick Reference (Presets - Recommended)" section - New "Available CMake Presets" table with all 16+ presets - Updated all build instructions to show both preset and traditional approaches - Expanded CMake options documentation with new quality/analysis options: - ADA_DEVELOPER_MODE - ADA_WARNINGS_AS_ERRORS - ADA_ENABLE_CLANG_TIDY - ADA_ENABLE_CPPCHECK - Rewrote "Complete Development Workflow" with preset-first approach - Updated summary tables comparing preset vs traditional approaches - Added reference to CMAKE_BEST_PRACTICES.md **docs/CMAKE_BEST_PRACTICES.md** - Added new "CI/CD Integration" section - Documents how workflows use presets - Shows benefits of preset consistency between local dev and CI ## Benefits 1. **CI/CD Consistency**: Workflows now use same presets as local development 2. **Maintainability**: Less duplication of CMake flags across workflows 3. **Clarity**: Preset names (ci, sanitize-address) clearly document intent 4. **User Experience**: CLAUDE.md now guides users to modern approach first 5. **Backward Compatibility**: Traditional CMake commands still documented and supported ## Migration Path Users can continue using traditional CMake commands (fully supported), but are now encouraged to adopt presets for: - Simpler command-line invocations - Standardized configurations - Better IDE integration - Consistency with CI/CD All changes maintain 100% backward compatibility with existing workflows. --- .github/workflows/ubuntu-release.yml | 10 +- .github/workflows/ubuntu-sanitized.yml | 8 +- .github/workflows/ubuntu-undef.yml | 8 +- .github/workflows/ubuntu.yml | 10 +- CLAUDE.md | 217 ++++++++++++++++++++++--- docs/CMAKE_BEST_PRACTICES.md | 37 +++++ 6 files changed, 250 insertions(+), 40 deletions(-) diff --git a/.github/workflows/ubuntu-release.yml b/.github/workflows/ubuntu-release.yml index 92de5a415..63df21c17 100644 --- a/.github/workflows/ubuntu-release.yml +++ b/.github/workflows/ubuntu-release.yml @@ -30,11 +30,11 @@ jobs: -
