# libnextcloud Shared Library Plan
**Created**: 2026-01-27
**Status**: 📋 Planning
**Target**: Cross-platform C++17 shared library for Nextcloud connectivity
**Branch**: `create-libnextcloud`
---
## Overview
Create `libnextcloud` - a cross-platform C++17 shared library that provides Nextcloud connectivity for embedded devices and homebrew platforms. The library will handle all Nextcloud communication, authentication, file operations, and settings management through a clean, platform-agnostic API.
**Design Philosophy**:
- **Platform-agnostic**: Works on 3DS, Switch, Wii U, Vita, PC, etc.
- **Minimal dependencies**: Only libcurl, mbedTLS, and tinyxml2
- **Header-only where possible**: nlohmann/json for configuration
- **Modern C++17**: Using standard library features
- **Testable**: Mock-friendly design with dependency injection
- **Documented**: Doxygen API documentation

// Core HTTP
Response get(const std::string& path);
Response put(const std::string& path, const std::vector<uint8_t>& data);
Response delete_(const std::string& path);
// WebDAV operations
std::vector<FileInfo> propfind(const std::string& path, int depth = 1);

## Build System Design
### CMakeLists.txt Structure
```cmake
cmake_minimum_required(VERSION 3.15)
project(libnextcloud VERSION 0.1.0 LANGUAGES CXX)
# C++17 required
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

)
# Dependencies
find_package(CURL REQUIRED)
find_package(MbedTLS REQUIRED)
find_package(tinyxml2 REQUIRED)

install(TARGETS nextcloud EXPORT nextcloudTargets)
install(DIRECTORY include/ DESTINATION include)
install(EXPORT nextcloudTargets
FILE nextcloudTargets.cmake
NAMESPACE nextcloud::
DESTINATION lib/cmake/nextcloud
)
```
### Platform-Specific Considerations
**Nintendo 3DS**:
- Static library only (no shared objects)
- mbedTLS available via dkp-pacman
- libcurl with 3DS patches
- Filesystem: `/nextcloud-share/config.json`
**Nintendo Switch**:
- Static library
- Standard libcurl and mbedTLS
- Filesystem: `/switch/nextcloud-share/config.json`
**Linux/PC**:
- Shared library (.so) or static
- System libcurl and mbedTLS
- Filesystem: `~/.config/nextcloud-share/config.json`
---
## Testing Strategy
### Unit Tests
- Mock all external dependencies (HTTP, filesystem)
- Test each class in isolation
- Cover edge cases and error conditions
- Fast execution (<1 second total)
### Integration Tests
- Real HTTP requests to test Nextcloud servers
- Require valid credentials from config.json
- Test full workflows end-to-end
- Can be skipped if credentials not available
### Performance Tests
- Upload 1GB file and measure time
- Upload 1000 small files
- Concurrent uploads
- Memory usage profiling
### Test Configuration
```json
{
"test": {
"servers": [
{
"name": "tomusan",
"url": "https://cloud.tomusan.com",
"username": "test",
"password": "xxx"
},
{
"name": "disobedient",
"url": "https://disobedient.cloud/nextcloud",
"username": "test",
"password": "xxx"
}
]
}
}
```

## Timeline Estimate
**Total Estimated Time**: 56-74 hours
| Phase | Tasks | Estimated Time |
|-------|-------|----------------|
| 1. Scaffolding | Project setup | 4-6 hours |
| 2. WebDAV Client | HTTP/WebDAV implementation | 12-16 hours |
| 3. Authentication | Auth system | 6-8 hours |
| 4. Upload Manager | File uploads | 10-12 hours |
| 5. Folder Management | Folder operations | 8-10 hours |
| 6. Favorites/Recent | Config persistence | 6-8 hours |
| 7. Testing/Docs | Tests and docs | 10-12 hours |
**Realistic Timeline**: 2-3 weeks working part-time (15-20 hrs/week)
---
## Success Criteria
The library is complete when:
- ✅ All phases implemented and tested
- ✅ Code coverage >80%
- ✅ Integration tests pass with real Nextcloud
- ✅ API documentation complete
- ✅ Examples compile and run
- ✅ Can be integrated into 3DS app
- ✅ Ready for additional platforms (Switch, Wii U, etc.)
---
## Next Steps
1. **Review this plan** - Adjust scope, estimates, priorities
2. **Create Gitea issues** - One for scaffolding, update existing issues
3. **Start Phase 1** - Set up project structure
4. **Implement phases sequentially** - Each phase depends on previous
5. **Test continuously** - Don't defer testing to the end
---
**Ready to proceed?** Let's create the issues and start building!

#include <nextcloud/types.hpp>
#include <iostream>
int main() {
// Get library version
std::cout << "libnextcloud v" << nextcloud::getVersionString() << std::endl;
// Check version compatibility
if (nextcloud::isVersionAtLeast(0, 1, 0)) {
std::cout << "Version is compatible!" << std::endl;
}

### Error Handling
```cpp
#include <nextcloud/types.hpp>
// Error codes
enum class NextcloudError {
Success,
NetworkError,
AuthenticationFailed,
ServerError,
FileNotFound,
// ... more error codes
};
// Convert to string
const char* errorToString(NextcloudError error);
// Result type
nextcloud::Result<int> result;
if (result.isSuccess()) {
// Use result.value
} else {
std::cerr << result.errorMessage() << std::endl;
}
```
### Data Structures
```cpp
// Upload progress
struct UploadProgress {
std::string filename;
uint64_t bytesUploaded;
uint64_t totalBytes;
float percentComplete;
float bytesPerSecond;
int secondsRemaining;
};
// File information
struct FileInfo {
std::string name;
std::string path;
bool isDirectory;
uint64_t size;
std::time_t modifiedTime;
std::string contentType;
};
// Folder information
struct FolderInfo {
std::string path;
std::string displayName;
std::time_t lastUsed;
bool isFavorite;
};
```
## Testing
```bash
# Run all tests
cd build
ctest --output-on-failure
# Or use the custom target
make run_tests
# Run specific test
./tests/smoke_test
```
