ComfyUI Node: 🪠️ WWAA Advanced Text File Reader

🪠️ WWAA Advanced Text File Reader:

The WWAA_AdvancedTextFileReader is a versatile node designed to read text files and output their contents in a structured manner, making it particularly useful for processing text data generated by other nodes, such as the LLM Prompt To Text File. This node is capable of handling text files by reading them line by line, allowing you to traverse through the file in various modes such as forward, reverse, or random. It provides a convenient way to access specific lines of text, which can be particularly beneficial when dealing with large datasets or when you need to extract specific information from a text file. The node also offers features like skipping lines, resetting the reading counter, and holding the current text, which enhances its flexibility and usability in different scenarios. By using this node, you can efficiently manage and manipulate text data, making it an essential tool for AI artists who work with text-based inputs and outputs.

🪠️ WWAA Advanced Text File Reader Input Parameters:

file_path

The file_path parameter specifies the location of the text file you wish to read. It is a required parameter and should be provided as a string. This parameter is crucial as it directs the node to the correct file from which to read the text data. Ensure that the file path is accurate and accessible to avoid errors during execution.

traversal_mode

The traversal_mode parameter determines the order in which the lines of the text file are read. It offers three options: "forward", "reverse", and "random", with "forward" being the default. This parameter allows you to control the sequence of line reading, which can be useful for different processing needs, such as reading the file from start to finish, from end to start, or in a non-sequential order.

skip_lines

The skip_lines parameter allows you to specify the number of lines to skip after each read operation. It is an integer value with a default of 0, and it can range from 0 to 10. This parameter is useful when you want to process only specific lines of a file, effectively ignoring a set number of lines between reads.

reset_counter

The reset_counter parameter is a boolean that, when set to true, resets the reading counter to the starting index. This is useful if you need to reprocess the file from a specific point without reloading the entire file. The default value is false.

reload_file

The reload_file parameter is a boolean that, when enabled, forces the node to reload the text file. This is particularly useful if the file content has changed and you need to ensure that the latest data is being read. The default value is false.

hold_current_text

The hold_current_text parameter is a boolean that, when set to true, holds the current line of text, preventing the node from moving to the next line on subsequent executions. This can be useful when you need to repeatedly process the same line of text. The default value is false.

starting_index

The starting_index parameter is an optional integer that specifies the line number from which to start reading the file. It has a default value of 0 and can be adjusted to begin reading from any line within the file. This parameter provides flexibility in accessing specific parts of the text file directly.

🪠️ WWAA Advanced Text File Reader Output Parameters:

current_line_text

The current_line_text output provides the text content of the current line being read from the file. This output is essential for accessing and utilizing the specific line of text that the node is currently processing.

current_line_number

The current_line_number output indicates the line number of the current line being read, starting from 1. This output is useful for tracking the position within the file and for reference purposes when processing text data.

total_lines

The total_lines output provides the total number of lines present in the text file. This information is valuable for understanding the size of the file and for planning the traversal or processing strategy.

remaining_lines

The remaining_lines output indicates the number of lines left to be read in the file from the current position. This output helps in determining how much of the file is yet to be processed, which can be useful for progress tracking and decision-making during file processing.

🪠️ WWAA Advanced Text File Reader Usage Tips:

• Use the traversal_mode parameter to customize the reading order of your text file, which can be particularly useful for different processing needs or when analyzing data in a non-linear fashion.
• Utilize the hold_current_text feature when you need to repeatedly process the same line of text, such as when performing iterative operations or when the same data needs to be referenced multiple times.
• Consider setting the reload_file parameter to true if you expect the text file content to change during processing, ensuring that the node always reads the most up-to-date data.

🪠️ WWAA Advanced Text File Reader Common Errors and Solutions:

File not found

• Explanation: This error occurs when the specified file path does not point to an existing file.
• Solution: Verify that the file_path parameter is correct and that the file exists at the specified location.

Index out of range

• Explanation: This error happens when the node attempts to access a line number that exceeds the total number of lines in the file.
• Solution: Ensure that the starting_index and any line-skipping logic do not exceed the total number of lines in the file.

File access denied

• Explanation: This error occurs when the node does not have the necessary permissions to read the specified file.
• Solution: Check the file permissions and ensure that the node has read access to the file.

Invalid traversal mode

• Explanation: This error arises when an unsupported value is provided for the traversal_mode parameter.
• Solution: Ensure that the traversal_mode is set to one of the supported options: "forward", "reverse", or "random".
