From c2ad55eaafb3392b3c52040e927981d18c67af9f Mon Sep 17 00:00:00 2001 From: Ole-Morten Duesund Date: Fri, 1 Aug 2025 21:26:53 +0200 Subject: [PATCH] feat: add comprehensive README documentation and clean up configuration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Documentation Enhancements - Create comprehensive README with installation, configuration, and usage examples - Add simple, advanced, and provider-specific configuration examples - Document all features: incremental sync, wildcard patterns, keyword filtering, attachment support - Include production deployment guidance and troubleshooting section - Add architecture documentation with database structure and document format examples ## Configuration Cleanup - Remove unnecessary `database` field from CouchDB configuration - Add `m2c_` prefix to all CouchDB database names for better namespace isolation - Update GenerateAccountDBName() to consistently prefix databases with `m2c_` - Clean up all configuration examples to remove deprecated database field ## Test Environment Simplification - Simplify test script structure to eliminate confusion and redundancy - Remove redundant populate-test-messages.sh wrapper script - Update run-tests.sh to be comprehensive automated test with cleanup - Maintain clear separation: automated tests vs manual testing environment - Update all test scripts to expect m2c-prefixed database names ## Configuration Examples Added - config-simple.json: Basic single Gmail account setup - config-advanced.json: Multi-account with complex filtering and different providers - config-providers.json: Real-world configurations for Gmail, Outlook, Yahoo, iCloud ## Benefits - Clear documentation for users from beginner to advanced - Namespace isolation prevents database conflicts in shared CouchDB instances - Simplified test workflow eliminates user confusion about which scripts to use - Comprehensive examples cover common email provider configurations ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 55 ++-- README.md | 388 ++++++++++++++++++++++++++++- config-advanced.json | 78 ++++++ config-providers.json | 90 +++++++ config-simple.json | 26 ++ config.json | 3 +- go/config/config.go | 1 -
