llm_break: Create an 'llm_break' object

In tidyprompt: Prompt Large Language Models and Enhance Their Functionality

Create an llm_break object

Description

This object is used to break a extraction and validation loop defined in a prompt_wrap() as evaluated by send_prompt(). When an extraction or validation function returns this object, the loop will be broken and no further extraction or validation functions are applied; instead, send_prompt() will be able to return the result at that point. This may be useful in scenarios where it is determined the LLM is unable to provide a response to a prompt.

Usage

llm_break(object_to_return = NULL, success = FALSE)

Arguments

object_to_return

The object to return as the response result from send_prompt() when this object is returned from an extraction or validation function

success

A logical indicating whether the send_prompt() loop break should nonetheless be considered as a successful completion of the extraction and validation process. If FALSE, the object_to_return must be NULL (as the response result of send_prompt() will always be 'NULL' when the evaluation was unsuccessful); if FALSE, send_prompt() will also print a warning about the unsuccessful evaluation. If TRUE, the object_to_return will be returned as the response result of send_prompt() (and send_prompt()) will print no warning about unsuccessful evaluation)

Value

An list of class "llm_break" containing the object to return and a logical indicating whether the evaluation was successful

Examples

# Example usage within an extraction function similar to the one in 'quit_if()':
extraction_fn <- function(x) {
  quit_detect_regex <- "NO ANSWER"

  if (grepl(quit_detect_regex, x)) {
      return(llm_break(
        object_to_return = NULL,
        success = TRUE
      ))
  }

  return(x)
}

## Not run: 
  result <- "How many months old is the cat of my uncle?" |>
    answer_as_integer() |>
    prompt_wrap(
      modify_fn = function(prompt) {
        paste0(
          prompt, "\n\n",
          "Type only 'NO ANSWER' if you do not know."
        )
      },
      extraction_fn = extraction_fn,
      type = "break"
    ) |>
    send_prompt()
  result
  # NULL

## End(Not run)
