og

A smart file opener acting as a routing gateway.

og (Open Gateway) is a rule-based file opener. It works like a network gateway, but for your local files: it intercepts "open" requests and routes them to different applications based on rules you define.

Most operating systems enforce a simple "1-to-1" mapping between file extensions and applications, but og allows for "1-to-many" logic based on context.

For example, you can tell og to:

• Open .md files in your ~/work directory with Obsidian.
• Open .md files in ~/dev with VS Code.
• Open .ts files that are actually MPEG-TS video with QuickTime Player, while keeping your TypeScript files in your code editor.

Features

• Context-aware Routing: Match files using glob patterns, file extensions, MIME types, or magic bytes.
• TUI Config Manager(WIP): Includes a terminal user interface for managing rules and testing matches without editing TOML files manually.
• Performance: Written in Rust for minimal latency.
• System Fallback: Seamlessly falls back to system defaults when no rules match.
