SDXL Prompt Styler, a custom node for ComfyUI

SDXL Prompt Styler

SDXL Prompt Styler Advanced

SDXL Prompt Styler is a node that enables you to style prompts based on predefined templates stored in multiple JSON files. The node specifically replaces a {prompt} placeholder in the ‘prompt’ field of each template with provided positive text.

The node also effectively manages negative prompts. If negative text is provided, the node combines this with the ‘negative_prompt’ field from the template. If no negative text is supplied, the system defaults to using the ‘negative_prompt’ from the JSON template. This flexibility enables the creation of a diverse and specific range of negative prompts.

Important Update

With the latest changes, the file structure and naming convention for style JSONs have been modified. If you’ve added or made changes to the sdxl_styles.json file in the past, follow these steps to ensure your styles remain intact:

Backup: Before pulling the latest changes, back up your sdxl_styles.json to a safe location.

Migration: After updating the repository, create a new JSON file in the styles directory. Move your custom styles from the backup of sdxl_styles.json into this new file.

Unique Style Names: While the system now detects duplicates and appends a suffix to ensure uniqueness, it’s a best practice to ensure your style names are originally unique to prevent any potential confusion.

Managing Included JSON Files: If you prefer not to load specific included JSON files, consider renaming or moving them to a different location outside of the styles directory. The system will load all JSON files present in the specified directory.

New Features

Loading from Multiple JSON Files: The system can now load styles from multiple JSON files present in the specified directory, ensuring the uniqueness of style names by appending a suffix to duplicates.

Enhanced Error Handling: Improved error handling for file reading, data validity, and template replacement functions.

Usage Example with SDXL Prompt Styler

Template example from a JSON file:

[
    {
        "name": "base",
        "prompt": "{prompt}",
        "negative_prompt": ""
    },
    {
        "name": "sai-enhance",
        "prompt": "breathtaking {prompt} . award-winning, professional, highly detailed",
        "negative_prompt": "ugly, deformed, noisy, blurry, distorted, grainy"
    }
]

style = "sai-enhance"
text_positive = "a futuristic pop up tent in a forest"
text_negative = "dark"

The above will generate the following styled prompts:

text_positive_styled = "breathtaking a futuristic pop up tent in a forest . award-winning, professional, highly detailed"
text_negative_styled = "ugly, deformed, noisy, blurry, distorted, grainy, dark"
