ComfyUI Node: LogicUtil_Merge String

LogicUtil_Merge String:

The LogicUtil_MergeString node is designed to concatenate two input values into a single string. This node is particularly useful when you need to combine different pieces of text or data into one continuous string, making it easier to manage and manipulate text-based information. Whether you are merging user inputs, combining dynamic data, or simply formatting strings for display, this node provides a straightforward and efficient way to achieve your goal. By converting the inputs to strings before concatenation, it ensures compatibility with various data types, enhancing its versatility and ease of use.

LogicUtil_Merge String Input Parameters:

input1

This parameter represents the first input value to be concatenated. It can be of any type, including strings, numbers, or boolean values. The node will convert this input to a string before merging it with the second input. The default value for this parameter is an empty string ("").

input2

This parameter represents the second input value to be concatenated. Similar to input1, it can be of any type, and the node will convert it to a string before performing the concatenation. The default value for this parameter is also an empty string ("").

LogicUtil_Merge String Output Parameters:

STRING

The output of this node is a single concatenated string that combines input1 and input2. This output is useful for creating formatted text, combining dynamic data, or preparing strings for further processing or display.

LogicUtil_Merge String Usage Tips:

• Use this node to combine user inputs or dynamic data into a single string for easier management and display.
• Ensure that the inputs are meaningful when converted to strings to avoid unexpected results.
• This node can be particularly useful in scenarios where you need to format text by combining static and dynamic content.

LogicUtil_Merge String Common Errors and Solutions:

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

• Explanation: This error occurs when one of the inputs is None, which cannot be concatenated with a string.
• Solution: Ensure that both input1 and input2 are not None before passing them to the node. You can use default values or pre-check the inputs to avoid this error.

Unexpected output format

• Explanation: The concatenated result may not be as expected if the inputs are not properly formatted or contain unexpected characters.
• Solution: Verify the inputs before concatenation to ensure they are in the desired format. You can use additional nodes to clean or format the inputs if necessary.
