ComfyUI Node: LogicUtil_Manual Choice String

LogicUtil_Manual Choice String:

The LogicUtil_ManualChoiceString node is designed to parse an input string based on a specified separator and return a specific choice from the parsed elements. This node is particularly useful when you need to extract a specific part of a string that is delimited by a character, such as $. By providing the index of the desired element, you can easily retrieve and use that part of the string in your workflow. This functionality is beneficial for scenarios where you need to dynamically select and use different parts of a string based on varying conditions or inputs.

LogicUtil_Manual Choice String Input Parameters:

input_string

The input_string parameter is the string that you want to parse and extract a specific element from. This string should contain elements separated by a specified separator. The default value is "a$b$c", which means the string is divided into parts by the $ character. This parameter is crucial as it provides the raw data from which a specific choice will be extracted.

separator

The separator parameter defines the character used to split the input_string into separate elements. The default value is $, but you can change it to any character that suits your needs. This parameter allows flexibility in how the input string is parsed, enabling you to work with different formats of delimited strings.

index

The index parameter specifies the position of the element you want to extract from the parsed input_string. It is an integer value with a default of 0, meaning it will select the first element by default. The minimum value is 0, and the maximum value is 9999999999. This parameter is essential for pinpointing the exact element you need from the split string.

LogicUtil_Manual Choice String Output Parameters:

STRING

The output of the LogicUtil_ManualChoiceString node is a single string element extracted from the input_string based on the specified separator and index. This output is crucial as it provides the specific part of the string that you need for further processing or use in your workflow.

LogicUtil_Manual Choice String Usage Tips:

• Ensure that the input_string contains the separator character; otherwise, the entire string will be treated as a single element.
• Use the index parameter carefully to avoid out-of-range errors. Always check the length of the parsed elements if the index is dynamically set.
• Customize the separator to match the delimiter used in your specific string format for accurate parsing.

LogicUtil_Manual Choice String Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the specified index is greater than the number of elements in the parsed input_string.
• Solution: Ensure that the index value is within the range of the number of elements in the input_string. You can add validation to check the length of the parsed elements before setting the index.

ValueError: invalid literal for int() with base 10

• Explanation: This error occurs if the input_string contains non-integer elements and you attempt to convert them to an integer.
• Solution: Ensure that the elements in the input_string are valid integers if you are using a node that expects integer outputs. Validate the input string format before processing.
