(It is meant to cover 90% of the prompt use cases, where no extreme
customization is required. For more complex input, it is required to create
a custom :class:`~Application` instance.)
message : Text to be shown before the prompt.
mulitiline : Allow multiline input. Pressing enter will insert a
newline. (This requires Meta+Enter to accept the input.)
wrap_lines : `bool` or :class:`~prompt_toolkit.filters.CLIFilter`.
When True (the default), automatically wrap long lines instead of
scrolling horizontally.
is_password : Show asterisks instead of the actual typed characters.
vi_mode : `bool` or :class:`~prompt_toolkit.filters.CLIFilter`. If
True, use Vi key bindings.
complete_while_typing : `bool` or
:class:`~prompt_toolkit.filters.CLIFilter`. Enable autocompletion while
typing.
enable_history_search : `bool` or
:class:`~prompt_toolkit.filters.CLIFilter`. Enable up-arrow parting
string matching.
lexer : :class:`~prompt_toolkit.layout.lexers.Lexer` to be used for
the syntax highlighting.
validator : :class:`~prompt_toolkit.validation.Validator` instance
for input validation.
completer : :class:`~prompt_toolkit.completion.Completer` instance
for input completion.
reserve_space_for_menu : Space to be reserved for displaying the menu.
(0 means that no space needs to be reserved.)
auto_suggest : :class:`~prompt_toolkit.auto_suggest.AutoSuggest`
instance for input suggestions.
style : Pygments style class for the color scheme.
enable_system_bindings : `bool` or
:class:`~prompt_toolkit.filters.CLIFilter`. Pressing Meta+'!' will show
a system prompt.
enable_open_in_editor : `bool` or
:class:`~prompt_toolkit.filters.CLIFilter`. Pressing 'v' in Vi mode or
C-X C-E in emacs mode will open an external editor.
history : :class:`~prompt_toolkit.history.History` instance.
clipboard : :class:`~prompt_toolkit.clipboard.base.Clipboard` instance.
(e.g. :class:`~prompt_toolkit.clipboard.in_memory.InMemoryClipboard`)
get_bottom_toolbar_tokens : Optional callable which takes a
:class:`~prompt_toolkit.interface.CommandLineInterface` and returns a
list of tokens for the bottom toolbar.
display_completions_in_columns : `bool` or
:class:`~prompt_toolkit.filters.CLIFilter`. Display the completions in
multiple columns.
get_title : Callable that returns the title to be displayed in the
terminal.
mouse_support : `bool` or :class:`~prompt_toolkit.filters.CLIFilter`
to enable mouse support.
default : The default text to be shown in the input buffer. (This can
be edited by the user.)
