    This extension provides the following utility nodes:

    🔤 MQ Text Splitter

    Splits text into a list based on a delimiter with advanced control options.

    • Inputs:
      • text: The input text to split
      • delimiter: The character(s) to split by (supports escape sequences like \n)
      • start_index: Starting position in the result list
      • skip_every: Skip N items between selections
      • max_count: Maximum number of items to return
    • Outputs:
      • STRING LIST: Array of split text items
      • LENGTH: Number of items in the result

    🔀 MQ Int Switch

    Conditional integer value selector based on a boolean condition.

    • Inputs:
      • if_true: Value to return when condition is true
      • if_false: Value to return when condition is false
      • condition: Boolean condition to evaluate
    • Output: Selected integer value

    🔢 MQ Int To String

    Converts integer values to string format.

    • Input: Integer value (supports large numbers from -1e9 to 1e9)
    • Output: String representation of the integer

    🖥️ MQ Check FP4 Support

    Checks if your GPU supports FP4 (4-bit floating point) operations.

    • Output: Boolean indicating FP4 support (requires GPU compute capability > 9.0)
