SDXL Prompt Styler:

The SDXLPromptStyler is a versatile node designed to enhance and stylize text prompts for AI art generation. Its primary function is to process and combine user-provided positive and negative text prompts with predefined style templates, allowing for the creation of more nuanced and contextually rich inputs for AI models. By leveraging a library of styles, this node enables you to apply consistent thematic or stylistic elements to your prompts, which can significantly influence the output of AI-generated art.

SDXL Prompt Styler Input Parameters:

text_positive

This parameter accepts a positive text prompt that you wish to stylize. It serves as the primary input for generating styled prompts, and its content will be modified according to the selected style template. The parameter is a multiline string, allowing for detailed and complex prompts. There is no explicit minimum or maximum length, but the default is an empty string.

text_negative

This parameter is used to input a negative text prompt, which can be combined with the style template's negative elements. Like the positive prompt, it is a multiline string, providing flexibility in crafting detailed negative prompts. The default value is an empty string, with no specified length constraints.

style

The style parameter allows you to select a predefined style template from a list of available options. This selection determines how the positive and negative prompts are modified and combined. The styles are loaded from a directory and offer various thematic or artistic influences. There are no minimum or maximum values, as this is a categorical selection.

log_prompt

This parameter controls whether the styled prompts and related information are printed to the console for review. It is a categorical option with two choices: "No" (default) and "Yes". Enabling logging can be useful for debugging or refining your prompt styling process.
