remindctl is a macOS command-line interface for Apple Reminders, built with Swift and Apple's EventKit framework. It provides a comprehensive set of commands to create, edit, complete, delete, and search reminders, manage lists, set due dates, alarms, recurrence, location triggers, and URLs. The application is structured as a modular library (RemindCore) containing the core EventKit interaction and business logic, and a CLI executable (remindctl) that uses the Commander library for command routing and argument parsing. The CLI supports multiple output formats (JSON, plain, table, quiet) and includes advanced features like fuzzy list name resolution, stable numeric indexing across reordered fetches, and a custom async timeout pattern for system operations. The codebase demonstrates strong Swift concurrency practices (async/await, actors), comprehensive unit tests, and a well-documented release pipeline with signed notarized binaries and Homebrew distribution.
Remindian is a macOS menu bar application that synchronizes tasks between Obsidian (as the source of truth) and various task management systems including Apple Reminders, Things 3, Todoist, TickTick, Asana, Linear, and Calendar Feed. The app allows users to configure multiple sync profiles, each connecting a source (Obsidian Vault, TaskNotes, or Generic Markdown) to a destination task service. It runs in the background with manual or scheduled synchronization, provides UI for configuration and monitoring, and includes safety features like automatic backups before file modifications, audit logging, and conflict resolution where Obsidian always wins as the source of truth. The architecture follows a layered pattern with SwiftUI for the presentation layer, a service layer for platform-specific integrations, a model layer for data structures, and protocol-based abstractions (TaskSource/TaskDestination) that enable pluggable implementations. The SyncManager acts as the central coordinator, while the SyncEngine orchestrates the synchronization process. Key features include bidirectional sync with configurable directions, duplicate detection, natural language task entry, and extensive customization options for field mapping and filtering. The application demonstrates strong engineering practices with a comprehensive test suite, careful attention to data integrity through surgical file edits and backup systems, and thoughtful handling of platform-specific integrations. While deeply integrated with macOS and specific task services, it maintains clean separation of concerns through its protocol-oriented design, making core components potentially reusable in other synchronization contexts.
Memo is a Python CLI tool for managing Apple Notes and Apple Reminders directly from the terminal. It uses Click for command-line interface and AppleScript (via osascript) to interact with macOS's Notes and Reminders applications. The application provides commands to list, view, add, edit, delete, move, search, and export notes, as well as manage reminders (list, complete, add, delete, edit). Notes are fetched as HTML from Apple Notes, converted to Markdown for display and editing, and images are handled via a placeholder mechanism to preserve inline images through edit cycles. The architecture is a standard CLI application with helper modules for each operation, caching for notes, and validation for flag combinations. It is well-tested with pytest, uses modern Python 3.13, and has a professional CI/CD pipeline and documentation site.
