You can use the ask_* functions from the ida_kernwin module.

For example:

  • ask_long: Display a dialog box and wait for the user to input an number
  • ask_str: Display a dialog box and wait for the user to input a text string
  • ask_file: Display a dialog box and wait for the user to input a file name
  • ask_form: Display a dialog box and wait for the user

There are also the choose_* functions if you want the user to choose something from the database (function, segment, structure). And fully customisable forms (see this example).

  • The ida_kernwin module is part of IDAPython. Try pasting the following code into the interpreter in the Output window: ida_kernwin.ask_str("Default value", 0, "Please enter string")
