This repository provides two lightweight execution helpers for ComfyUI graphs:

• Shell Code – run arbitrary /bin/bash scripts with STRING input and capture the stdout as both text and (optionally) a LIST of lines.
• Python Code – run inline Python snippets that operate on a provided string and expose structured results, captured stdout, and error information.

    __init__.py          # exports both node classes
    shell_code_node.py   # Shell Code node implementation
    python_code_node.py  # Python Code node implementation
requirements.txt         # empty placeholder (no deps)

Clone this repository directly into ComfyUI/custom_nodes or install it via ComfyUI Manager once published.

Outputs (stdout, stdout_lines, stderr, ok) where stdout_lines is marked as a LIST output to allow wiring into other nodes.

Outputs (result, result_lines, stdout, stderr, ok) where:

• result comes from the result (or result_text) variable inside the script.
• result_lines can be directly assigned inside the script, otherwise it will be auto-populated from result when splitting is enabled.
• stdout captures anything printed by the script.
• stderr contains the formatted traceback if an exception occurs.
• ok is True when the script executes without raising.

Both nodes are intentionally minimal wrappers over standard interpreters and do not provide sandboxing. Only run them on systems you control and never expose them to untrusted input.
