hex1b

What problem does it solve?

Hex1b removes flaky, manual testing and demo recording of terminal-based apps by letting you programmatically control interactive programs, inspect what they render, and wait for specific output reliably.

Core Features & Use Cases

• Virtual terminal automation: Start TUI apps, shells, REPLs, and interactive CLIs inside a headless virtual terminal for repeatable runs.
• Screen capture for verification: Capture terminal output as text, ANSI, SVG, PNG, or HTML to create assertions and visual evidence.
• Deterministic interaction: Inject keyboard and mouse input and use wait/assert operations to avoid timing issues.
• Workflow examples: End-to-end scripted tests for interactive UIs; capturing recordings for demos; validating that expected menus, errors, or prompts appear.

Quick Start

Start a process in a virtual terminal and then assert that the expected text appears before sending any input: run dotnet hex1b terminal start with a command, then use dotnet hex1b assert on the returned terminal id with the target text and a timeout.
