omfg - Org Mode File Gossip

Minimal iOS app for editing daily org-mode notes with syncthing sync.

Features

• Opens today's daily note (daily/MM-DD.org)
• Regex-based org-mode syntax highlighting (headers, TODO/DONE, links, bold, italic, timestamps)
• Auto-save with 500ms debounce
• External file change detection
• Syncthing sync in foreground only

Build

Prerequisites

• Xcode 15+ with iOS SDK
• Go 1.21+

Setup Xcode

# Ensure full Xcode is selected (not Command Line Tools)
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

Build Go Framework (optional - app works without sync)

go install golang.org/x/mobile/cmd/gomobile@latest
go install golang.org/x/mobile/cmd/gobind@latest
make framework

Build App

1. Open OMFG.xcodeproj in Xcode
2. If using syncthing: Add Syncthing.xcframework (Embed & Sign)
3. Build and run (Cmd+R)

Architecture

• UIKit + TextKit: NSTextStorage subclass for syntax highlighting
• No storyboards: Programmatic UI
• Foreground sync: Syncthing stops 3s after backgrounding
• Last write wins: Simple conflict resolution
