ComfyUI Extension: simple wildcard for ComfyUI

simple wildcard for ComfyUI Introduction

ComfyUI_node_Lilly is an extension designed to enhance the capabilities of AI artists by providing advanced wildcard functionalities. This extension allows you to create more dynamic and varied text prompts, which can be particularly useful in generating diverse and creative AI art. By using wildcards, you can introduce randomness and variability into your prompts, making your AI-generated art more unique and interesting.

How simple wildcard for ComfyUI Works

At its core, ComfyUI_node_Lilly uses wildcards to replace parts of your text prompts with random or predefined values. Think of wildcards as placeholders that can be filled with different options each time you run your prompt. This can help you generate a wide range of outputs from a single prompt template.

For example, if you have a prompt like a{__b__|{c|}|{__d__|e|}|f|}g____ __my__, the extension will replace the placeholders (__b__, __d__, __my__, etc.) with different values based on the rules you define. This can result in various combinations, making your AI art more diverse.

Wildcards

Wildcards are the main feature of this extension. They allow you to define parts of your prompt that can be replaced with different values. Here are some examples:

• {1|2|3}: This will randomly choose between 1, 2, or 3.
• {2$$a|b|c}: This will choose two of the options (a, b, c) in any combination.
• {1-2$$a|b|c}: This will choose between one and two of the options.
• {*}: This matches any value.

Wildcard Text File Use

You can also use text files to define your wildcards. For example, if you have a file ~/a/b.txt with the content 1, and another file ~/b.txt with the content 2, you can use these files in your wildcards:

• __b__ will be replaced with 1 or 2.
• __/b will be replaced with 2.
• __/a/b will be replaced with 1.

Filename Pattern Matching

The extension supports filename pattern matching using special characters:

• * matches everything.
• ? matches any single character.
• [seq] matches any character in the sequence.
• [!seq] matches any character not in the sequence. For more details, you can refer to the Python fnmatch documentation.

CLIPTextEncodeWildcards

This feature allows you to encode text prompts with wildcards, either with or without a seed. This can help you generate consistent results if you use the same seed, or more varied results if you don't.

SimpleSampler+modelVAE

This feature includes wildcards and allows you to sample from a model with a variational autoencoder (VAE). This can help you generate more diverse and high-quality images.

VAELoaderText, LoraLoaderText, CheckpointLoaderSimpleText

These loaders support filename wildcards, allowing you to dynamically load different models or checkpoints based on your wildcard patterns.
