Zerna Pack is a collection of custom nodes for ComfyUI designed to facilitate batch processing of text and images. It includes tools for dynamic prompt generation and other utilities to enhance your workflow.

Features

Dynamic Prompt Injector: Generate prompts dynamically by replacing placeholders with content from text files.
Batch Processing: Process multiple prompts or images efficiently.

Installation

Clone or download the repository into the custom_nodes directory of your ComfyUI installation:
```
git clone https://github.com/RaymondProduction/comfyui-zerna-pack.git
```
Ensure that ComfyUI is installed and properly configured. No additional dependencies are required as this pack uses only the standard library and ComfyUI core.

Usage

Dynamic Prompt Injector

Place your .txt files containing prompt data in the prompts directory:
```
comfyui-zerna-pack/prompts/
```
Example files:
- test.txt:
```
hello
```
- example01.txt:
```
cat
dog
pig
```
Use the Dynamic Prompt Injector node in ComfyUI:
- Set the prompt_text field with a template containing [X] as a placeholder.
- Select a .txt file from the prompt_file dropdown.
- Configure optional parameters like reload, load_cap, and start_index as needed.
The node will replace [X] in the prompt_text with each line from the selected file and output the processed prompts.

Example

Input:
- prompt_text: "A photo of [X] in the forest."
- prompt_file: example01.txt

Output:

A photo of cat in the forest.
A photo of dog in the forest.
A photo of pig in the forest.
