ComfyUI Node: LogicUtil_String List to Combo

LogicUtil_String List to Combo:

The LogicUtil_StringListToCombo node is designed to take a raw string, split it into a list of substrings based on a specified separator, and then return a specific element from this list. This node is particularly useful when you need to parse a string containing multiple values separated by a common delimiter and extract a specific value from the resulting list. It simplifies the process of handling and manipulating strings, making it easier to work with structured data embedded in text form. By allowing you to specify an index, it provides flexibility in selecting which part of the split string you want to use, enhancing your ability to manage and utilize string data effectively.

LogicUtil_String List to Combo Input Parameters:

string

This parameter represents the raw string that you want to split and process. It is the main input for the node and should contain the text data you wish to manipulate. The default value is an empty string (""), and it can be any string value. If the string is a numeric or boolean value, it will be returned as is without any splitting.

separator

The separator parameter defines the character or string used to split the main input string into a list of substrings. The default value is "$". If the separator is not found in the string, the entire string is returned as a single element. This parameter allows you to control how the string is divided, which is crucial for correctly parsing the input data.

index

This optional parameter specifies the position of the element to be returned from the list of substrings created by splitting the input string. The default value is 0, meaning the first element will be returned. If the specified index is out of range (i.e., greater than the number of elements in the list), the last element of the list will be returned. This parameter provides flexibility in selecting which part of the split string you need.

LogicUtil_String List to Combo Output Parameters:

anytype

The output of this node is a single element from the list of substrings created by splitting the input string. The type of this output can vary depending on the input string and the specified index. If the input string is numeric or boolean, the output will be of the same type. Otherwise, it will be a string representing the selected substring. This output is essential for further processing or analysis in your workflow.

LogicUtil_String List to Combo Usage Tips:

• Ensure that the separator parameter matches the delimiter used in your input string to correctly split the string into the desired substrings.
• Use the index parameter to select specific elements from the split string, which can be useful for extracting particular values from structured text data.
• If you are unsure about the structure of your input string, consider using a default separator and index to test the node's behavior before fine-tuning the parameters.

LogicUtil_String List to Combo Common Errors and Solutions:

Separator not found in string

• Explanation: The specified separator is not present in the input string, so the entire string is returned as a single element.
• Solution: Verify that the separator parameter matches the delimiter used in your input string. Adjust the separator value if necessary.

Index out of range

• Explanation: The specified index is greater than the number of elements in the list created by splitting the input string.
• Solution: Ensure that the index parameter is within the valid range of the list. If you need the last element, you can set the index to a value greater than or equal to the length of the list.

Input string is numeric or boolean

• Explanation: The input string is a numeric or boolean value, so it is returned as is without any splitting.
• Solution: If you intend to split a string, ensure that the input is a text string and not a numeric or boolean value. Adjust the input accordingly.
