A native macOS terminal emulator with advanced tab group management, built with Swift and SwiftUI.

"Tabula" - from "tabula rasa" (clean slate) - fresh terminal sessions organized by tabs.

• Organize terminals by project - Create multiple groups for different tasks or projects
• Collapsible sidebar - Only the active group is expanded, keeping your workspace clean
• Visual thumbnails - See a preview of each terminal session in the sidebar
• Auto-save/restore - Your workspace is automatically saved and restored between sessions

• ⌘N - Create new tab group
• ⌘T - Create new tab in current group
• ⌃Tab / ⌃⇧Tab - Cycle through tabs in current group
• ⌃⌥Tab / ⌃⌥⇧Tab - Cycle through groups

• Font selection and sizing
• Color scheme (Light, Dark, System)
• Full VT100/xterm terminal emulation via SwiftTerm

• AppState - Global application state managing all groups
• TabGroup - Collection of terminal tabs with shared context
• TerminalTab - Individual terminal session

• SidebarView - Collapsible group list with thumbnails
• TerminalView - SwiftTerm integration for terminal emulation
• PreferencesView - Application settings

• PTYController - PTY management and shell process lifecycle
• PersistenceManager - Save/restore app state to disk
• ThumbnailGenerator - Generate visual previews of terminal sessions

Perfect for developers who work on multiple projects simultaneously:

• Web Development: Group 1 might have tabs for server logs, dev tools, editor, and database console
• Backend Services: Group 2 for microservices with a tab per service
• DevOps: Group 3 for monitoring, deployment scripts, and SSH sessions
• Personal Projects: Group 4 for side projects

No more juggling multiple terminal windows or losing track of which tab belongs to which project!

Session data is automatically saved to:

~/Library/Application Support/Tabula/state.json

• macOS 14.0+ (Sonoma)
• Xcode 15.0+ (for development)
• Swift 5.9+

• SwiftTerm - Terminal emulation engine
