## Project Structure

Projects created with ccgo follow this structure:

```
my-project/
├── CCGO.toml                   # CCGO project config
├── CMakeLists.txt              # Root CMake configuration
├── src/                        # Source code
├── include/                    # Public headers

```

## SDK Archive Structure

When you run `ccgo build <target>`, the output is placed in `target/{debug|release}/<platform>/` with a unified archive structure.

### Archive Naming Convention

```
{PROJECT}_{PLATFORM}_SDK-{version}[-{suffix}].zip        # Main SDK archive
{PROJECT}_{PLATFORM}_SDK-{version}[-{suffix}]-SYMBOLS.zip  # Debug symbols archive
```

**Examples:**
- `MYLIB_ANDROID_SDK-1.0.0-release.zip`
- `MYLIB_IOS_SDK-1.0.0-beta.5-dirty.zip`
- `MYLIB_LINUX_SDK-2.1.0-SYMBOLS.zip`

### Unified SDK Archive Structure

All platforms follow the same archive structure:

```
{PROJECT}_{PLATFORM}_SDK-{version}.zip
├── lib/{platform}/
│   ├── static/                    # Static libraries (.a, .lib)
│   │   └── [{arch}/]              # Architecture subdirectory (if multi-arch)

### Excluded Files

The following files are automatically excluded from archives:
- `CPPLINT.cfg`
- `.clang-format`
- `.clang-tidy`

## Features System

CCGO supports a features system similar to Cargo's, enabling conditional compilation and optional dependencies. This allows you to:

- Enable/disable parts of your library at build time
- Make dependencies optional and only include them when needed
- Define feature groups that enable multiple sub-features

### Defining Features in CCGO.toml

```toml
[package]
name = "mylib"
version = "1.0.0"

[features]
# Default features enabled when none are specified
default = ["std"]

# Feature definitions
std = []
networking = ["http-client"]        # Enables optional dependency
advanced = ["networking", "async"]  # Enables other features
full = ["networking", "advanced", "logging"]

# Dependency feature syntax
derive = ["serde/derive"]           # Enables feature on dependency

[[dependencies]]
name = "http-client"
version = "^1.0"
optional = true                     # Only included when enabled by a feature

[[dependencies]]
name = "async"
version = "^2.0"
optional = true

[[dependencies]]
name = "serde"
version = "^1.0"
features = ["std"]                  # Features to enable on this dependency
default_features = false            # Disable dependency's default features
```

### Using Features in Builds

```bash
# Build with default features
ccgo build android

# Build with specific features
ccgo build android --features networking,advanced

# Build without default features
ccgo build linux --no-default-features

# Build with specific features, no defaults
ccgo build linux --no-default-features --features minimal

# Build with all available features
ccgo build ios --all-features
```

### CMake Integration

Features are passed to CMake as compile definitions with the `CCGO_FEATURE_` prefix:

```cmake
# In your CMakeLists.txt, check for features:
if(DEFINED CCGO_FEATURE_DEFINITIONS)
    foreach(def ${CCGO_FEATURE_DEFINITIONS})
        target_compile_definitions(${PROJECT_NAME} PRIVATE ${def})
    endforeach()
endif()
```

In your C++ code:

```cpp
#ifdef CCGO_FEATURE_NETWORKING
#include "networking/http_client.h"
#endif

#ifdef CCGO_FEATURE_ADVANCED
void advanced_function() {
    // Advanced implementation
}
#endif
```

### Feature Resolution

Features are resolved transitively:

1. **Default features** are enabled unless `--no-default-features` is specified
2. **Requested features** from `--features` are added
3. **Transitive features** are resolved (e.g., `full` enables `advanced` which enables `networking`)
4. **Optional dependencies** are included only if enabled by an active feature

Example resolution for `--features full`:
```
full → advanced, networking, logging
advanced → networking, async
networking → http-client (optional dep)
```

Result: `full`, `advanced`, `networking`, `logging`, `async`, `http-client` are all enabled.

## Workspaces

CCGO supports workspaces for managing multiple related packages in a single repository. Workspaces provide:

- Unified dependency management across packages
- Shared configuration and settings
- Single-command builds for all packages

### Creating a Workspace

Create a root `CCGO.toml` with a `[workspace]` section:

```toml
# Root CCGO.toml (workspace root)
[workspace]
members = [
    "core",
    "utils",
    "examples/*"      # Glob patterns supported
]
exclude = ["examples/deprecated"]
resolver = "2"        # Dependency resolver version

# Shared dependencies for workspace members
[[workspace.dependencies]]
name = "fmt"
version = "^10.0"
git = "https://github.com/fmtlib/fmt.git"
features = ["std"]

[[workspace.dependencies]]
name = "spdlog"
version = "^1.12"
```

### Workspace Member Configuration

Member packages can inherit dependencies from the workspace:

```toml
# core/CCGO.toml
[package]
name = "my-core"
version = "1.0.0"

[[dependencies]]
name = "fmt"
workspace = true          # Inherit from workspace
features = ["extra"]      # Additional features (merged with workspace)

[[dependencies]]
name = "spdlog"
workspace = true
```

### Workspace Structure

```
my-workspace/
├── CCGO.toml              # Workspace root configuration
├── core/
│   ├── CCGO.toml          # Member package
│   ├── CMakeLists.txt
│   └── src/
├── utils/
│   ├── CCGO.toml          # Member package
│   ├── CMakeLists.txt
│   └── src/
└── examples/
    ├── demo1/
    │   └── CCGO.toml      # Member (matched by glob)
    └── deprecated/
        └── CCGO.toml      # Excluded member
```

### Workspace with Root Package

A workspace root can also be a package itself (virtual workspace):

```toml
[workspace]
members = ["crates/*"]

[package]
name = "my-workspace-root"
version = "1.0.0"
```

### Dependency Inheritance

When a member uses `workspace = true`:

1. **Version** is inherited from workspace if not specified locally
2. **Git/Path** sources are inherited from workspace
3. **Features** are merged (workspace features + local features)
4. **default_features** uses workspace setting if not specified locally

```toml
# Workspace defines:
[[workspace.dependencies]]
name = "fmt"
version = "^10.0"
features = ["std"]

# Member uses:
[[dependencies]]
name = "fmt"
workspace = true
features = ["color"]  # Results in: ["std", "color"]
```

### Resolver Versions

- `resolver = "1"` - Legacy resolver (default)
- `resolver = "2"` - New resolver with better feature unification across packages

## Advanced Usage

### Using Custom Templates

You can create projects from custom templates:

```bash
# From GitHub repository
ccgo new my-project --template-url=https://github.com/user/my-template.git

# From local directory
ccgo new my-project --template-url=/path/to/local/template
```

### CI/CD Integration

The generated `build.py` script supports CI/CD workflows with environment variables:

- `CI_IS_RELEASE` - Build as release vs beta
- `CI_BUILD_<PLATFORM>` - Enable/disable platform builds

Example:

```bash
export CI_IS_RELEASE=1
export CI_BUILD_ANDROID=1
export CI_BUILD_IOS=1
python3 build.py
```

### Multi-Architecture Builds

Build for multiple architectures simultaneously:

```bash
# Android: build for 32-bit ARM, 64-bit ARM, and x86_64
ccgo build android --arch armeabi-v7a,arm64-v8a,x86_64

# OHOS: build for all supported architectures
ccgo build ohos --arch armeabi-v7a,arm64-v8a,x86_64
```

## Troubleshooting

### Common Issues

1. **"Command not found" after installation**

   - Ensure `pip` or `cargo` install directory is in your PATH
   - For pip: typically `~/.local/bin` (Linux/macOS) or `%APPDATA%\Python\Scripts` (Windows)
   - For cargo: typically `~/.cargo/bin`
