ComfyUI Node: 🔠 String ⁄ List Operations

🔠 String ⁄ List Operations:

The StringOperation node is a versatile tool designed to perform a wide range of operations on strings or lists of strings. This node is particularly useful for AI artists who need to manipulate text data within their workflows. Whether you need to compare, concatenate, count, or transform strings, this node provides a comprehensive set of operations to meet your needs. It simplifies complex string manipulations, making it easier to handle text data without requiring extensive programming knowledge. By leveraging this node, you can streamline your text processing tasks, ensuring efficient and accurate results.

🔠 String ⁄ List Operations Input Parameters:

input

This parameter accepts the string or list of strings that you want to process. It is the primary data on which the selected operation will be performed. The input can be a single string or a list of strings, depending on the operation you choose.

operation

This parameter specifies the operation to perform on the input. Available options include COMPARE, CONCATENATE, COUNT, ENDS_WITH, EXTRACT_BETWEEN, FIND, GENERATE, GET_LINE, IS_ALPHA, IS_NUMERIC, JOIN, LENGTH, LOWERCASE, PROPERCASE, REPLACE, RANDOM_INPUT, RANDOM_ELEMENT, REVERSE, SLICE, SPLIT, SPLIT_LINES, STARTS_WITH, STRIP, TO_LIST, TO_STRING, TRIM_SPACES, and UPPERCASE. Each operation performs a specific function on the input, such as comparing strings, concatenating them, or converting their case.

start_from_end

This boolean parameter determines whether to evaluate the input from the start or the end of the expression. It is useful for operations that can be performed in reverse order, such as REVERSE or SLICE. The default value is False.

case_insensitive

This boolean parameter specifies whether to ignore case sensitivity for operations that support it. When set to True, the operation will treat uppercase and lowercase characters as equivalent. The default value is False.

aux1

This optional parameter can be of any type and is used as an auxiliary input for certain operations. For example, it can specify the characters to strip in the STRIP operation or the substring to find in the FIND operation. The exact usage depends on the selected operation.

aux2

This optional parameter can be of any type and is used as an additional auxiliary input for certain operations. For example, it can specify the replacement string in the REPLACE operation. The exact usage depends on the selected operation.

aux3

This optional parameter can be of any type and is used as a third auxiliary input for certain operations. For example, it can specify the maximum number of replacements in the REPLACE operation. The exact usage depends on the selected operation.

🔠 String ⁄ List Operations Output Parameters:

output

This parameter provides the processed input value after the chosen operation has been applied. The output can be a modified string or list of strings, depending on the operation performed. For example, if the UPPERCASE operation is selected, the output will be the input string converted to uppercase.

result

This parameter indicates the result of the chosen operation. It can be a boolean value, a count, or another relevant result based on the operation. For example, in the COMPARE operation, the result will be True or False depending on whether the comparison was successful.

🔠 String ⁄ List Operations Usage Tips:

• Use the case_insensitive parameter to handle text data without worrying about case differences, especially for operations like FIND or COMPARE.
• Leverage the start_from_end parameter for operations that can benefit from reverse evaluation, such as REVERSE or SLICE.
• Utilize the aux1, aux2, and aux3 parameters to provide additional context or data required for specific operations, ensuring more precise and tailored text manipulations.

🔠 String ⁄ List Operations Common Errors and Solutions:

"Aux1 must be a positive number for the GET_LINE operation!"

• Explanation: This error occurs when the GET_LINE operation is selected, but the aux1 parameter is not a positive number.
• Solution: Ensure that the aux1 parameter is set to a positive number when using the GET_LINE operation.

"File already exists and 'new only' is selected."

• Explanation: This error occurs when attempting to write to a file with the mode set to new only, but the file already exists.
• Solution: Change the mode to append or overwrite, or ensure that the file does not already exist when using the new only mode.

"Variable 'x' is not defined"

• Explanation: This error occurs when a variable used in the operation is not defined in the local or global scope.
• Solution: Ensure that all variables used in the operation are properly defined and accessible within the scope of the node.
