feat: implement Go-based mail2couch with working IMAP and CouchDB integration
- Add configuration system with automatic file discovery (current dir, config subdir, user home, XDG config) - Implement IMAP client with TLS connection, authentication, and mailbox listing - Add CouchDB integration with database creation and document storage - Support folder filtering (include/exclude) and date filtering (since parameter) - Include duplicate detection to prevent re-storing existing messages - Add comprehensive error handling and logging throughout - Structure code in clean packages: config, mail, couch - Application currently uses placeholder messages to test the storage pipeline - Ready for real IMAP message parsing implementation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
mail2couch is a utility for backing up mail from various sources (primarily IMAP) to CouchDB. The project supports two implementations:
|
||||
- **Go implementation**: Located in `/go/` directory (currently the active implementation)
|
||||
- **Rust implementation**: Planned but not yet implemented
|
||||
|
||||
## Development Commands
|
||||
|
||||
### Go Implementation (Primary)
|
||||
|
||||
```bash
|
||||
# Build the application
|
||||
cd go && go build -o mail2couch .
|
||||
|
||||
# Run the application with automatic config discovery
|
||||
cd go && ./mail2couch
|
||||
|
||||
# Run with specific config file
|
||||
cd go && ./mail2couch -config /path/to/config.json
|
||||
|
||||
# Run linting/static analysis
|
||||
cd go && go vet ./...
|
||||
|
||||
# Run tests (currently no tests exist)
|
||||
cd go && go test ./...
|
||||
|
||||
# Check dependencies
|
||||
cd go && go mod tidy
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Core Components
|
||||
|
||||
1. **Configuration (`config/`)**: JSON-based configuration system
|
||||
- Supports multiple mail sources with filtering options
|
||||
- CouchDB connection settings
|
||||
- Each source can have folder and message filters
|
||||
|
||||
2. **Mail Handling (`mail/`)**: IMAP client implementation
|
||||
- Uses `github.com/emersion/go-imap/v2` for IMAP operations
|
||||
- Supports TLS connections
|
||||
- Currently only lists mailboxes (backup functionality not yet implemented)
|
||||
|
||||
3. **CouchDB Integration (`couch/`)**: Database operations
|
||||
- Uses `github.com/go-kivik/kivik/v4` as CouchDB driver
|
||||
- Handles database creation and document management
|
||||
- Defines `MailDocument` structure for email storage
|
||||
|
||||
### Configuration Structure
|
||||
|
||||
The application uses `config.json` for configuration with the following structure:
|
||||
- `couchDb`: Database connection settings (URL, credentials, database name)
|
||||
- `mailSources`: Array of mail sources with individual settings:
|
||||
- Protocol support (currently only IMAP)
|
||||
- Connection details (host, port, credentials)
|
||||
- Filtering options for folders and messages
|
||||
- Enable/disable per source
|
||||
|
||||
### Configuration File Discovery
|
||||
|
||||
The application automatically searches for configuration files in the following order:
|
||||
1. Path specified by `-config` command line flag
|
||||
2. `./config.json` (current working directory)
|
||||
3. `./config/config.json` (config subdirectory)
|
||||
4. `~/.config/mail2couch/config.json` (user XDG config directory)
|
||||
5. `~/.mail2couch.json` (user home directory)
|
||||
|
||||
This design ensures the same `config.json` format will work for both Go and Rust implementations.
|
||||
|
||||
### Current Implementation Status
|
||||
|
||||
- ✅ Configuration loading with automatic file discovery
|
||||
- ✅ Command line flag support for config file path
|
||||
- ✅ CouchDB client initialization and database creation
|
||||
- ✅ IMAP connection and mailbox listing
|
||||
- ✅ Build error fixes
|
||||
- ✅ Email message retrieval framework (with placeholder data)
|
||||
- ✅ Email storage to CouchDB framework
|
||||
- ✅ Folder filtering logic
|
||||
- ✅ Date filtering support
|
||||
- ✅ Duplicate detection and prevention
|
||||
- ❌ Real IMAP message parsing (currently uses placeholder data)
|
||||
- ❌ Full message body and attachment handling
|
||||
- ❌ Incremental sync functionality
|
||||
- ❌ Rust implementation
|
||||
|
||||
### Key Dependencies
|
||||
|
||||
- `github.com/emersion/go-imap/v2`: IMAP client library
|
||||
- `github.com/go-kivik/kivik/v4`: CouchDB client library
|
||||
|
||||
### Development Notes
|
||||
|
||||
- The main entry point is `main.go` which orchestrates the configuration loading, CouchDB setup, and mail source processing
|
||||
- Each mail source is processed sequentially with proper error handling
|
||||
- The application currently uses placeholder message data for testing the storage pipeline
|
||||
- Message filtering by folder (include/exclude) and date (since) is implemented
|
||||
- Duplicate detection prevents re-storing existing messages
|
||||
- No tests are currently implemented
|
||||
- The application uses automatic config file discovery as documented above
|
||||
|
||||
### Next Steps
|
||||
|
||||
To complete the implementation, the following items need to be addressed:
|
||||
|
||||
1. **Real IMAP Message Parsing**: Replace placeholder message generation with actual IMAP message fetching and parsing using the correct go-imap/v2 API
|
||||
2. **Message Body Extraction**: Implement proper text/plain and text/html body extraction from multipart messages
|
||||
3. **Attachment Handling**: Add support for email attachments (optional)
|
||||
4. **Error Recovery**: Add retry logic for network failures and partial sync recovery
|
||||
5. **Performance**: Add batch operations for better CouchDB insertion performance
|
||||
6. **Testing**: Add unit tests for all major components
|
||||
|
||||
## Development Guidelines
|
||||
|
||||
### Code Quality and Standards
|
||||
- All code requires perfect linting and tool-formatting, exceptions are allowed only if documented properly
