ComfyUI Node: 🎲 Random line from input

🎲 Random line from input:

The Bjornulf_RandomLineFromInput node is designed to randomly select a line from a given block of text. This node is particularly useful when you have a large text input and need to extract a single line at random, which can be beneficial for tasks that require sampling or randomization of text data. By leveraging a seed value, this node ensures that the random selection process can be consistent and reproducible, allowing for controlled randomness in your workflows. This feature is especially valuable in creative AI applications where unpredictability is desired, yet repeatability is necessary for testing and refinement.

🎲 Random line from input Input Parameters:

text

The text parameter is a string input that contains the block of text from which a random line will be selected. This input is crucial as it provides the source material for the node's operation. The text should be formatted with lines separated by newline characters. The node will process this input by splitting it into individual lines, removing any empty lines or leading and trailing whitespace, and then selecting one line at random. There are no specific minimum or maximum values for this parameter, but it should be a valid string with at least one non-empty line to function correctly.

seed

The seed parameter is an integer that determines the randomness of the line selection process. By setting a specific seed value, you can ensure that the random line selection is consistent across multiple runs, which is useful for debugging or when you need to reproduce results. The default value for this parameter is 1, but it can be set to any integer value. The choice of seed affects the sequence of random numbers generated, and thus the line that is selected from the input text.

🎲 Random line from input Output Parameters:

STRING

The output of the Bjornulf_RandomLineFromInput node is a single string, which is the randomly selected line from the input text. This output is significant as it provides a specific line from the text block, chosen based on the randomization process influenced by the seed. The output will be an empty string if the input text does not contain any valid lines. This output can be used in subsequent nodes or processes where a single line of text is required.

🎲 Random line from input Usage Tips:

• Ensure that your input text is well-formatted with lines separated by newline characters to maximize the effectiveness of the random selection.
• Use different seed values to explore various random selections from the same text input, which can be useful for generating diverse outputs in creative projects.

🎲 Random line from input Common Errors and Solutions:

No valid lines found in input text

• Explanation: This error occurs when the input text does not contain any non-empty lines after processing.
• Solution: Check the input text to ensure it contains valid lines separated by newline characters and that there are no formatting issues.

Counter has reached the last line (total lines: X). Reset Counter to continue.

• Explanation: This error is not directly related to this node but may occur in similar contexts where line processing is involved. It indicates that a counter used for line selection has exceeded the available lines.
• Solution: Reset the counter or adjust the input text to include more lines if applicable.
