+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Atom is a foundational C++23 library for astronomical software providing core utilities, algorithms, and system interfaces. The project is organized into modular components that can be built selectively.
+
+## Build System
+
+This project uses CMake as the primary build system with a unified Makefile interface.
+
+### Common Build Commands
+
+```bash
+# Build entire project (default Release mode)
+make build
+
+# Build with different configurations
+make debug # Debug build
+make release # Release build
+make python # Build with Python bindings
+make all # Build everything (tests, examples, docs, Python)
+
+# Testing
+make test # Run all tests
+make test-coverage # Run tests with coverage analysis
+
+# Development tools
+make format # Format code with clang-format
+make analyze # Run static analysis with clang-tidy
+make clean # Clean build artifacts
+
+# Single test execution (use ctest in build directory)
+cd build && ctest -R --output-on-failure
+```
+
+### CMake Build Options
+
+Key configuration options:
+
+- `ATOM_BUILD_TESTS=ON/OFF` - Build test suite
+- `ATOM_BUILD_EXAMPLES=ON/OFF` - Build example programs
+- `ATOM_BUILD_PYTHON_BINDINGS=ON/OFF` - Build Python bindings
+- `ATOM_BUILD_DOCS=ON/OFF` - Generate documentation
+- `ATOM_BUILD_ALL=ON/OFF` - Build all modules
+- `ATOM_BUILD_TESTS_SELECTIVE=ON/OFF` - Enable selective test building
+- Individual module flags: `ATOM_BUILD_=ON/OFF` for ALGORITHM, ASYNC, etc.
+
+### Selective Building
+
+Use selective build options to build only specific modules:
+
+```bash
+cmake -DATOM_BUILD_ALL=OFF -DATOM_BUILD_ASYNC=ON -DATOM_BUILD_ALGORITHM=ON ..
+```
+
+## Architecture
+
+### Core Modules
+
+The library is organized into these primary modules:
+
+- **algorithm** - Mathematical algorithms, cryptography, compression, pathfinding
+- **async** - Asynchronous programming primitives (futures, promises, thread pools, message queues)
+- **components** - Component system with dependency injection and registry
+- **connection** - Network communication (TCP/UDP, FIFO, SSH clients/servers)
+- **error** - Error handling, exception management, stack traces
+- **image** - FITS file handling, image processing, OCR, SER format support
+- **io** - File operations, compression, glob patterns, async I/O
+- **log** - Logging infrastructure with async capabilities
+- **memory** - Memory management utilities, pools, smart pointers
+- **meta** - Template metaprogramming, reflection, type manipulation
+- **search** - Search engines, caching (LRU, TTL), database interfaces
+- **secret** - Encryption, password management, secure storage
+- **serial** - Serial port communication, USB, Bluetooth interfaces
+- **sysinfo** - System information (CPU, memory, disk, GPU, network)
+- **system** - System utilities (processes, environment, crash handling, registry)
+- **type** - Advanced type utilities (JSON, containers, string manipulation)
+- **utils** - General utilities (time, conversion, validation, random generation)
+- **web** - HTTP utilities, network addressing, time management
+
+### Module Dependencies
+
+The modules have interdependencies - check individual CMakeLists.txt files for specific requirements. Core modules like `error`, `type`, and `utils` are foundational dependencies for higher-level modules.
+
+## Standards and Conventions
+
+- **C++ Standard**: C++23 (CMAKE_CXX_STANDARD=23)
+- **Coding Style**: Use `make format` to apply clang-format rules
+- **Platform Support**: Linux (primary), Windows, macOS with platform-specific implementations
+- **Dependencies**: See CMakeLists.txt for required packages (Asio, OpenSSL, SQLite3, fmt, etc.)
+
+## Testing
+
+- Tests are located in the `tests/` directory mirroring the module structure
+- Use CTest for test execution: `cd build && ctest --parallel`
+- Selective test building available via `ATOM_TEST_BUILD_` options
+- Performance and benchmark tests available in tests/
+
+## Development Environment
+
+Required tools:
+
+- CMake 3.21+
+- C++23 compliant compiler
+- Optional: clang-format, clang-tidy for code quality
+- Platform-specific dependencies (X11 on Linux, etc.)
+
+The build system auto-detects WSL environments and adjusts dependency handling accordingly.
+
+## Continuous Integration
+
+The project uses GitHub Actions for comprehensive multi-platform CI/CD with the following features:
+
+### Supported Platforms
+
+- **Linux**: Ubuntu 22.04 with GCC 12/13 and Clang 15/16
+- **Windows**: MSVC 2022, MSYS2 MinGW64, and UCRT64 environments
+- **macOS**: Latest versions with Clang
+
+### CI Features
+
+- **Multi-compiler Support**: GCC, Clang, MSVC across different versions
+- **MSYS2 Integration**: Full Windows MinGW64 support with native dependency management
+- **Advanced Caching**: vcpkg dependencies, build artifacts, and ccache for faster builds
+- **Test Matrix**: Debug/Release builds with sanitizers and coverage analysis
+- **Python Wheels**: Multi-platform wheel generation for Python 3.9-3.12
+- **Artifacts**: Automatic packaging (DEB, ZIP, MSI) and release deployment
+- **Performance**: Benchmark execution and performance tracking
+
+### Manual Workflow Triggers
+
+Use GitHub's workflow_dispatch to trigger builds with custom parameters:
+
+- Build type (Release/Debug/RelWithDebInfo)
+- Enable/disable tests and examples
+- Available in Actions tab of the repository
+
+### CI Presets
+
+The CI uses predefined CMake presets:
+
+- `release`, `debug`, `relwithdebinfo` for standard builds
+- `debug-full` for comprehensive testing with sanitizers
+- `coverage` for code coverage analysis
+- `release-msys2`, `debug-msys2` for MSYS2 MinGW64 builds
+- `release-vs`, `debug-vs` for Visual Studio builds

-# Atom xmake构建系统
-
-这个文件夹包含了使用xmake构建Atom库的配置文件。xmake是一个轻量级的跨平台构建系统，可以更简单地构建C/C++项目。
-
-## 安装xmake
-
-在使用本构建系统之前，请先安装xmake：
-
-- 官方网站：
-- GitHub：
-
-### Windows安装
-
-```powershell
-# 使用PowerShell安装
-Invoke-Expression (Invoke-Webrequest 'https://xmake.io/psget.ps1' -UseBasicParsing).Content
-```
-
-### Linux/macOS安装
-
-```bash
-# 使用bash安装
-curl -fsSL https://xmake.io/shget.text | bash
-```
-
-## 快速构建
-
-我们提供了简单的构建脚本来简化构建过程：
-
-### Windows
-
-```cmd
-# 默认构建（Release模式，静态库）
-build.bat
-
-# 构建Debug版本
-build.bat --debug
-
-# 构建共享库
-build.bat --shared
-
-# 构建Python绑定
-build.bat --python
-
-# 构建示例
-build.bat --examples
-
-# 构建测试
-build.bat --tests
-
-# 查看所有选项
-build.bat --help
-```
-
-### Linux/macOS
-
-```bash
-# 默认构建（Release模式，静态库）
-./build.sh
-
-# 构建Debug版本
-./build.sh --debug
-
-# 构建共享库
-./build.sh --shared
-
-# 构建Python绑定
-./build.sh --python
-
-# 构建示例
-./build.sh --examples
-
-# 构建测试
-./build.sh --tests
-
-# 查看所有选项
-./build.sh --help
-```
-
-## 手动构建
-
-如果你想手动配置构建选项，可以使用以下命令：
-
-```bash
-# 配置项目
-xmake config [选项]
-
-# 构建项目
-xmake build
-
-# 安装项目
-xmake install
-```
-
-### 可用的配置选项
-
-- `--build_python=y/n`: 启用/禁用Python绑定构建
-- `--shared_libs=y/n`: 构建共享库或静态库
-- `--build_examples=y/n`: 启用/禁用示例构建
-- `--build_tests=y/n`: 启用/禁用测试构建
-- `--enable_ssh=y/n`: 启用/禁用SSH支持
-- `-m debug/release`: 设置构建模式
-
-例如：
-
-```bash
-xmake config -m debug --build_python=y --shared_libs=y
-```
-
-## 项目结构
-
-这个构建系统使用了模块化的设计，每个子目录都有自己的`xmake.lua`文件：
-
-- `xmake.lua`：根配置文件
-- `atom/xmake.lua`：主库配置
-- `atom/*/xmake.lua`：各模块配置
-- `example/xmake.lua`：示例配置
-- `tests/xmake.lua`：测试配置
-
-## 自定义安装位置
-
-你可以通过以下方式指定安装位置：
-
-```bash
-xmake install -o /path/to/install
-```
-
-## 打包
-
-你可以使用xmake的打包功能创建发布包：
-
-```bash
-xmake package
-```
-
-## 清理构建文件
-
-```bash
-xmake clean
-```
-
-## 故障排除
-
-如果遇到构建问题，可以尝试以下命令：
-
-```bash
-# 清理所有构建文件并重新构建
-xmake clean -a
-xmake
-
-# 查看详细构建信息
-xmake -v
-
-# 更新xmake并重试
-xmake update
-xmake
-```
