Obsidian Task Export Plugin - Implementation Summary

Overview

Successfully implemented a complete Obsidian plugin that ports the logic from the C# console application markdown-task-export. The plugin provides native Obsidian integration with command palette, settings UI, ribbon icon, status bar, and automatic file watching.

Implementation Status: ✅ COMPLETE

Core Features Implemented

1. Task Parser (src/parser.ts)

   • Direct port of C# MarkdownParser.cs
   • Detects unchecked tasks: - [ ]
   • Ignores completed tasks: - [x] and checkmark indicators
   • Extracts hierarchical headers (##, ###, ####, etc.) - unlimited depth
   • Handles nested tasks with parent task promotion to header levels
   • Preserves empty hierarchy slots for structure

2. CSV Writer (src/csv-writer.ts)

   • Direct port of C# CsvExporter.cs
   • RFC 4180 compliant CSV escaping
   • UTF-8 with BOM encoding for Excel compatibility
   • Dynamic column generation based on max hierarchy depth
   • Compress levels mode (removes empty columns)
   • Header row control (include/exclude)

3. Task Exporter (src/exporter.ts)

   • Direct port of C# TaskExtractor.cs
   • Scans vault folders recursively
   • Extracts customer name from folder structure
   • Extracts project name from filename
   • Uses Obsidian Vault API (cross-platform compatible)
   • Proper error handling for missing files/folders

4. File Watcher (src/file-watcher.ts)

   • Debounced file change detection (configurable 1-30 seconds)
   • Filters to only markdown files in configured folder
   • Enable/disable auto-export on demand
   • Prevents excessive exports during bulk edits

5. Settings UI (src/settings.ts)

   • Full Obsidian settings tab integration
   • All 9 settings configurable via UI
   • Real-time updates
   • Input validation

6. Main Plugin (src/main.ts)

   • Ribbon icon (file-text) for quick export
   • Status bar with relative time display
   • Three commands:
     • Export Outstanding Tasks
     • Toggle Auto-Export
     • Open Export Settings
   • Notification system for success/error feedback
   • Concurrent export prevention
