TouchDesigner Framework CLI scaffold tool for opinionated State Driven Command and Control/Code Driven project architecture

tdfw

TouchDesigner Framework CLI scaffold tool with an opinionated slant towards State Driven/Code Driven project architecture.

About

Hi, I'm Michael. I play guitar and write code. I was introduced to TouchDesigner by my friend Andrew Zolty, who's also known as BREAKFAST. He's an incredible kinetic artist.

Getting started with TouchDesigner as a GUI never really happened for me. I started a few YouTube courses on it but didn't have the time to follow through and learn how to use the interface.

But the concept of a network of nodes and subnodes made sense to my programmer/software engineer brain. I thought "there must be a purely code driven way to architect these TouchDesinger apps". So I looked on YouTube and found this video (read more about that in BACKGROUND.md). I was thrilled and what has resulted is essentially this tool which abstracts out all the boilerplate he gives.

How To Use

# 1. Install prerequisites

# Make sure Python is installed and matches the TouchDesigner
# distributions version and a package manager like uv is 
# available globally.

# one level back from where you want your TD project 

# run: `uv venv` then activate the virtual environment
# you just created


# 2. Install tdfw in the venv
uv pip install --upgrade tdfw

# 3. Confirm installation and explore options
tdfw help

# 4. Doctor check (optional but recommended)
# Ensures uv/pip/conda and TouchDesigner paths are set up correctly.
tdfw doctor

# 5. Scaffold a new TouchDesigner App
tdfw start-app <MyFirstApp>

### Now hook in your TD project with this scaffolding
- **DAT/STARTUP/StartupExecute.py** is scaffolded automatically 
with the `onStart()` hook.  
- **Echo message** nudges the user only to open TD and save the `.toe`.  

This way, the scaffold is truly turnkey: once you save the `.toe`, the
 startup hook is already wired to your `StartupExt`.

Open TouchDesigner > 

File > Create Project Folder 

In dialog: 
  - Path: 
    > Use the file system nav to select ONE LEVEL BACK FROM THE ROOT 
        of Project you just created 
  - Project Folder:
    > name it EXACTLY this: {os.path.basename(app_name)}
   
  - Rename File: 
    > ENSURE CHECKED

  - Media Folders: 
    > Select/Unselect whatever Media Folders you want to create

Once this step is complete and the `.toe` file exists then you can open your project and code editor in one double-click on BAT/<app>.bat or BAT/<app>.bash files via your File Explorer
---

# 6. Open your app in your editor
cd <MyFirstApp>
code .   # or cursor ., vim ., etc.

# 7. Create Python Extension stubs
# Run from your TouchDesigner Project Root (the dir with <MyFirstApp>.toe)
tdfw create-ext <MyFirstExt>

# 8. Manage environments
# Initialize a uv environment (falls back to pip if uv is missing)
tdfw init-env <MyAppEnv>

# Export reproducible requirements for TouchDesigner
tdfw export-env --manager uv --output requirements.txt

# Import environment from requirements.txt or environment.yml
tdfw import-env requirements.txt

Philosophy

Legibility first: Every scaffolded app reads like a table of contents. Extensions are explicit, declarative, and easy to debug.

Environment reproducibility: uv.lock for developers, requirements.txt or environment.yml for TouchDesigner. Both humans and TD can bootstrap consistently.

Cross‑platform ready: .bat for Windows, .bash for macOS/Linux, with override support for TouchDesigner executable paths.

Doctor mindset: Always check your system before scaffolding — tdfw doctor ensures you’re ready.

Iterative growth: Start simple (one app, one extension), then evolve into complex state‑machine architectures without spaghetti networks.
