ComfyUI Node: LogicUtil_Yieldable Iterator String

LogicUtil_Yieldable Iterator String:

The LogicUtil_YieldableIteratorString node is designed to sequentially yield elements from a given input string, which is split based on a specified separator. This node is particularly useful when you need to process or iterate through a list of items in a controlled manner. If the reset parameter is set to True, the iteration starts from the beginning of the list; otherwise, it continues from where it left off. This functionality is beneficial for tasks that require repeated access to elements in a list without manually managing the iteration state.

LogicUtil_Yieldable Iterator String Input Parameters:

input_string

This parameter represents the string that will be split into individual elements based on the specified separator. The node will yield these elements one by one. The default value is "a$b$c", which means the string will be split into ["a", "b", "c"] if the separator is $.

separator

The separator is a string that defines how the input_string will be split into individual elements. For example, if the separator is $, the string "a$b$c" will be split into ["a", "b", "c"]. The default value is $.

reset

The reset parameter is an integer that determines whether the iteration should start from the beginning of the list. If set to 1 (True), the iteration resets to the first element. If set to 0 (False), the iteration continues from the last yielded element. The default value is 0, with a minimum value of 0 and a maximum value of 1.

LogicUtil_Yieldable Iterator String Output Parameters:

STRING

The output is a single string element from the list generated by splitting the input_string using the specified separator. This element is yielded sequentially based on the current state of the iterator.

LogicUtil_Yieldable Iterator String Usage Tips:

• To iterate through a list of items repeatedly, set the reset parameter to 1 after reaching the end of the list to start over from the beginning.
• Use a unique separator that does not appear in the elements of your input_string to ensure accurate splitting.
• If you need to process elements in a specific order, ensure that the input_string is formatted correctly and the separator is chosen appropriately.

LogicUtil_Yieldable Iterator String Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs if the node tries to access an element beyond the end of the list.
• Solution: Ensure that the input_string is correctly formatted and the separator is properly set. If the list is empty or the separator does not match, adjust the input_string and separator accordingly.

ValueError: empty separator

• Explanation: This error occurs if the separator is an empty string, which is not allowed.
• Solution: Set a valid non-empty string as the separator to split the input_string correctly.

TypeError: 'NoneType' object is not iterable

• Explanation: This error occurs if the input_string is None or not properly initialized.
• Solution: Ensure that the input_string is a valid string and not None. Initialize the input_string with a proper value before using the node.
