ComfyUI Node: Load Single Prompt From File (Inspire)

Load Single Prompt From File (Inspire):

The LoadSinglePromptFromFile (Inspire) node is designed to streamline the process of loading a single prompt from a specified file. This node is particularly useful for AI artists who work with predefined prompts stored in text files. By automating the extraction of prompts, it saves time and reduces the potential for manual errors. The node reads the content of the specified file, splits it into individual prompts, and extracts the positive and negative text components from the selected prompt. This functionality is essential for artists who need to quickly access and utilize specific prompts in their creative workflows.

Load Single Prompt From File (Inspire) Input Parameters:

prompt_file

The prompt_file parameter specifies the name of the file from which the prompt will be loaded. This file should be located in the predefined prompts directory. The parameter is crucial as it directs the node to the correct file containing the desired prompt. There are no specific minimum or maximum values for this parameter, but it must be a valid file name within the prompts directory.

index

The index parameter determines which prompt to load from the file. Prompts within the file are typically separated by a specific delimiter, and this index allows you to select the exact prompt you need. If the specified index is out of range, the node will default to the last prompt in the file. This parameter is essential for pinpointing the exact prompt to be used, especially in files containing multiple prompts. The index should be a non-negative integer.

Load Single Prompt From File (Inspire) Output Parameters:

prompts

The prompts output parameter is a list containing tuples of the form (positive_text, negative_text, prompt_file). Each tuple represents a single prompt extracted from the file, with positive_text and negative_text being the respective components of the prompt, and prompt_file indicating the source file. This output is crucial for downstream nodes or processes that utilize these text components for further operations, such as generating images or other creative outputs.

Load Single Prompt From File (Inspire) Usage Tips:

• Ensure that the prompt file is correctly formatted with clear delimiters between individual prompts to avoid extraction errors.
• Use the index parameter to select specific prompts from files containing multiple entries, which can help in testing and refining different prompt variations.
• Regularly update and organize your prompt files to maintain a smooth workflow and easy access to the latest prompts.

Load Single Prompt From File (Inspire) Common Errors and Solutions:

[WARN] LoadPromptsFromFile: invalid prompt format in '<prompt_file>'

• Explanation: This warning indicates that the format of the prompt in the specified file does not match the expected pattern.
• Solution: Check the prompt file to ensure that each prompt follows the correct format, with positive: and negative: sections clearly defined.

[ERROR] LoadPromptsFromFile: an error occurred while processing '<prompt_file>': <error_message>

• Explanation: This error occurs when there is an issue reading or processing the specified prompt file.
• Solution: Verify that the file exists in the correct directory, is accessible, and is not corrupted. Ensure that the file name is correctly specified in the prompt_file parameter.
