📄 README

comfydv

A collection of workflow efficiency and quality of life nodes that I’ve created for personal use out of necessity.

String Formatting: Use either plain python f-strings or more advanced Jinja2 templating to format outputs.

Random Choice: Add an abitrary number of inputs and then, with seed control, randomly select one for an output.

Documentation

Full documentation can be found: darth-veitcher.github.io/comfydv

String Formatting

The FormatString node provides flexible string formatting with dynamic input/output configuration.

Python F-String

A simple python f-string dynamically creates the necessary inputs/outputs for the detected keys.

Jinja 2

Switching to Jinja2 allows you to use more advanced control blocks and other filters/features of that templating language. See Jinja documentation for further details.

Output Structure

The node’s outputs are organized for maximum reliability and flexibility:

formatted_string (Output 0): The formatted result string – always in position 0

saved_file_path (Output 1): Path to saved state file (if save_path provided) – always in position 1

Variable outputs (Output 2+): Pass-through values for any variables detected in the template, enabling easy chaining

For example, with template "Hello {name}, you are {age}":

Output 0: The formatted string (e.g., “Hello Alice, you are 30”)

Output 1: The save file path (or empty string)

Output 2: The value of name (e.g., “Alice”)

Output 3: The value of age (e.g., “30”)

This structure ensures the primary outputs (formatted_string and saved_file_path) are always in predictable, fixed positions for reliable workflow connections.

Random Choice

Ability to take arbitrary length and type of inputs to then output a choice with a controllable seed.
