ComfyUI Node: textCycleLine

textCycleLine:

The ttN textCycleLine node is designed to help you cycle through lines of text efficiently. This node is particularly useful when you have a block of text and need to extract specific lines based on an index. It allows you to control the index dynamically, offering options to increment, decrement, randomize, or fix the index. This functionality is beneficial for tasks that require sequential or random access to lines of text, such as generating prompts or iterating through a list of instructions. By using this node, you can streamline your text processing workflow and ensure that you can easily access and manipulate specific lines of text as needed.

textCycleLine Input Parameters:

text

This parameter accepts a block of text as a string. The text can be multiline, and each line will be treated as a separate entry. This is the primary input from which lines will be cycled through based on the index. The default value is an empty string, and it supports dynamic prompts to allow for flexible text input.

index

The index parameter specifies the line number to be accessed from the provided text. It is an integer value that determines which line will be selected. The default value is 0, and it can range from 0 to a very large number (up to 0xffffffffffffffff). This parameter is crucial for pinpointing the exact line you want to retrieve.

index_control

This parameter controls how the index is managed. It offers four options: increment, decrement, randomize, and fixed. Increment will increase the index by one, decrement will decrease it by one, randomize will select a random index, and fixed will keep the index constant. This flexibility allows you to dynamically adjust the index based on your specific needs.

textCycleLine Output Parameters:

STRING

The output is a single line of text from the input block, corresponding to the specified index. This output is crucial for tasks that require specific lines of text to be extracted and used in subsequent operations. The output will be the line at the given index, making it easy to access and utilize specific parts of your text input.

textCycleLine Usage Tips:

• Use the randomize option in index_control to add variability to your text processing, which can be particularly useful for generating diverse prompts or instructions.
• If you need to process text sequentially, set index_control to increment and start with an index of 0 to cycle through each line one by one.
• For tasks that require specific lines to be accessed repeatedly, use the fixed option in index_control to maintain a constant index.

textCycleLine Common Errors and Solutions:

Index out of range

• Explanation: This error occurs when the specified index is greater than the number of lines in the text.
• Solution: Ensure that the index value is within the range of the number of lines in your text. You can also add a check to reset the index if it exceeds the number of lines.

Empty text input

• Explanation: This error occurs when the text input is empty or undefined.
• Solution: Provide a valid block of text as input. Ensure that the text parameter is not left empty and contains the lines you want to cycle through.

Invalid index_control value

• Explanation: This error occurs when an invalid value is provided for the index_control parameter.
• Solution: Use one of the valid options: increment, decrement, randomize, or fixed. Double-check the spelling and case of the value provided.
