Set callback for non-interactive user input — set_ask_user

Sets a legacy process-wide callback for non-interactive sessions. This fallback cannot isolate concurrent Agents or Shiny sessions. New code should bind a handler to a tool instance with tools_interactive().

Usage

set_ask_user_callback(callback)

Arguments

callback: A function that takes questions in Deputy's structured question format. Each question has question, header, options (list with label and description), and multiSelect. Should return a named list mapping question text to selected label(s). For multi-select, join labels with ", ". Set to NULL to clear the callback.

Value

Invisibly returns the previous callback (or NULL).

Examples

if (FALSE) { # \dontrun{
# Legacy fallback for a single-Agent script:
set_ask_user_callback(function(questions) {
  # Display questions in modal and collect answers
  answers <- list()
  for (q in questions) {
    # Collect one answer for each question.
    answers[[q$question]] <- selected_label
  }
  answers
})
} # }
