Set callback for non-interactive user input — set_ask_user

In non-interactive sessions (scripts, Shiny apps, etc.), set a callback function that will be called when the agent needs user input via AskUserQuestion.

Usage

set_ask_user_callback(callback)

Arguments

callback: A function that takes questions (list matching the AskUserQuestion 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{
# For a Shiny app:
set_ask_user_callback(function(questions) {
  # Display questions in modal and collect answers
  answers <- list()
  for (q in questions) {
    # Show q$question with q$options
    # Collect user selection
    answers[[q$question]] <- selected_label
  }
  answers
})
} # }
