pipedream-fiction 0.2.5

Real-time generative visualization for interactive fiction.

PipeDream

PipeDream is a utility that adds a visual dimension to text-based interactive fiction. It operates by capturing the standard output of terminal games and generating real-time illustrations of the current scene using generative AI.

Quick Start (30 Seconds)

Experience the visualization immediately with the built-in demo cartridge.

1. Install

pip install pipedream-fiction

2. Get an API Key You need a Gemini API key for the image generation (Free tier available).

• Get one here: Google AI Studio
• Set it in your terminal:

# Linux / macOS
export GEMINI_API_KEY="AIzaSy..."

# Windows (PowerShell)
$env:GEMINI_API_KEY="AIzaSy..."

3. Run the Demo Launch the GUI without arguments to play the internal mock game.

Running Real Games

PipeDream wraps any console command. If you can run a game in your terminal, PipeDream can visualize it.

Example: Colossal Cave Adventure

The perfect test bed for PipeDream.

1. Install the game globally:

uv tool install adventure
# Windows users: uv tool install adventure --with pyreadline3 --force

2. Launch with PipeDream:

pipedream-gui adventure

Example: Interactive Fiction (Frotz)

Play classic Z-Machine games like Zork.

Features

• Universal Compatibility: Works with Python scripts, binaries, and interpreters (Frotz, Glulxe).
• State-Aware Navigator: A graph-based system tracks movement. If you leave a room and come back, PipeDream restores the previous image.
• Cost Tracking: The GUI displays your session cost in real-time (via litellm), so you can monitor your API usage.
• Visual Consistency: The "Director" AI compares new text against previous context to prevent unnecessary regenerations when you mistype a command. (Attempts to at least!)

Customizing Styles

You can override the default art style ("Oil painting, dark fantasy") with the --art-style flag.

# Pixel Art Style
pipedream-gui --art-style "Retro 8-bit pixel art, green monochrome" adventure

# Pencil Sketch
pipedream-gui --art-style "Rough pencil sketch on parchment" adventure

Cache Management

PipeDream caches aggressively to save money. If you change styles, you can wipe the world map:

pipedream-gui --clear-cache adventure

Development

If you want to play around with the source code:

1. Clone the repo:

git clone [https://github.com/yourusername/pipedream.git](https://github.com/yourusername/pipedream.git)
cd pipedream

2. Install in editable mode:

pip install -e .

3. Configure Environment: Create a .env file in the root:

GEMINI_API_KEY=AIzaSy...
LLM_MODEL=gemini/gemini-2.5-flash
IMAGE_MODEL=gemini/gemini-2.5-flash-image

Troubleshooting

• Windows "Shim" Errors: If a Python game crashes immediately on Windows, try wrapping the command to force path resolution:

pipedream-gui cmd /c adventure
