ComfyUI Node: 🔢 Add line numbers

🔢 Add line numbers:

The Bjornulf_AddLineNumbers node is designed to enhance text readability by adding line numbers to each line of a given text input. This functionality is particularly useful for artists and developers who need to reference specific lines in a block of text, such as when reviewing scripts, code, or any structured text document. By automatically numbering each line, this node helps in organizing and navigating through the text more efficiently, making it easier to identify and discuss specific sections. The node processes the input text by splitting it into individual lines, appending a line number to each, and then reassembling the text into a single string with numbered lines. This feature is beneficial in collaborative environments where precise line referencing is crucial.

🔢 Add line numbers Input Parameters:

text

The text parameter is a required input that accepts a string of text, which can be multiline. This parameter is the core input for the node, as it is the text that will be processed to add line numbers. The function of this parameter is to provide the content that needs to be organized with line numbers. The impact of this parameter on the node's execution is direct, as the node will split this text into lines, number them, and then return the modified text. There are no specific minimum or maximum values for this parameter, but it must be a valid string input. The default setting requires the user to input the text manually, as it is a mandatory field for the node to function.

🔢 Add line numbers Output Parameters:

STRING

The output parameter is a STRING, which represents the processed text with line numbers added to each line. This output is crucial as it provides the user with a neatly organized version of the input text, where each line is prefixed with its corresponding line number. The interpretation of this output is straightforward: it is the original text, but with each line clearly numbered, making it easier to reference and discuss specific parts of the text. This output is particularly useful in scenarios where line-specific feedback or analysis is required.

🔢 Add line numbers Usage Tips:

• To ensure optimal performance, input text should be well-structured and free of unnecessary blank lines, as these will also be numbered.
• Use this node when preparing text for collaborative review sessions, as it allows for precise line referencing, which can facilitate clearer communication among team members.

🔢 Add line numbers Common Errors and Solutions:

No valid lines found in input text

• Explanation: This error occurs when the input text is empty or consists solely of whitespace, resulting in no valid lines to number.
• Solution: Ensure that the input text contains valid, non-empty lines. Remove any unnecessary whitespace or blank lines before processing.

Counter has reached the last line (total lines: <number>). Reset Counter to continue.

• Explanation: This error is related to the line counter reaching the end of the text, which is not directly applicable to the AddLineNumbers node but may occur in related processes.
• Solution: If encountered, check related nodes or processes that might be using a line counter and reset it as needed to continue processing.
