Features

For complete VT feature details, see TerminalCtrl's features list and technical specs document.

Core Features

• Cross-Platform Compatibility: Runs seamlessly on Linux, Windows, MacOS, and BSD, supporting multiple terminal backends with high VT (DEC/ANSI) and xterm compatibility.
• Inline Image Support: Displays images directly in the terminal with both Sixel and modern formats (PNG, JPG, BMP, TIFF), supporting multiple protocols such as iTerm2 and Jexer.
• Advanced Clipboard & Hyperlinks: Clickable links, OSC-based clipboard integration, and extended (rich-)text annotations for a modern workflow.
• Smart Shell Integration: Tracks working directories and allows opening them in the system's default file manager via shortcuts or menus.
• Versatile Text Selection: Selector mode with keyboard-driven selection, customizable regex-based patterns, and support for rectangular, word, and line selections.
• Full Mouse & Keyboard Support: Works across all major protocols, with customizable key bindings for a tailored experience.

Powerful Tools

• Finder Search Engine: A robust text search tool with case-sensitive/insensitive modes, regex search, and CSV extraction via Harvester Mode, preserving structured data integrity.
• Linkifier: Instantly turns text into clickable hyperlinks using custom regex patterns, adaptable per terminal profile.
• QuickText: Maintain a list of frequently used commands and snippets for fast insertion with a keyboard shortcut.

Customization & Interface

• Multiple Profiles: Configure different terminal settings and color schemes for various tasks.
• Split screen: You can spit the screen to 2 terminal panes side by side (vertical or horizontal).
• Minimal vs. Full UI: Choose between a lightweight or fully-featured interface with a stacked terminal manager for easy navigation.
• Simple Configuration: JSON-based configuration with real-time updates, or use a GUI settings panel—no manual file editing required.

Windows-Specific Features

• Multiple Pty Backends: Supports both ConPty and WinPty, with runtime switching for maximum flexibility.
• Standalone Compatibility: Works without external dependencies like msys2 or cygwin, but remains compatible with them.

Experimental Features

• Web Terminal Access: Run the terminal in a modern web browser via HTML5 Canvas, enabling remote access.
• Headless Mode: Operates on minimal setups via an SDL2-GL backend, eliminating GUI dependencies.

And yes—it can run Doom! 🎮

Requirements

2. Using Make (Linux)

• Uses pre-compiled umk (U++ make) for faster builds:

  1. make download
  2. make build or make build-web or make build-headless
  3. make run

3. Manual Setup
