If you are using this library for retrieving some input from the user (as a pure Python replacement for GNU readline), probably for 90% of the use cases, the :func:`.prompt` function is all you need. It's the easiest shortcut which does a lot of the underlying work like creating a :class:`~prompt_toolkit.interface.CommandLineInterface` instance for you. When is this not sufficient: - When you want to have more complicated layouts (maybe with sidebars or multiple toolbars. Or visibility of certain user interface controls according to some conditions.) - When you wish to have multiple input buffers. (If you would create an editor like a Vi clone.) - Something else that requires more customization than what is possible with the parameters of `prompt`. In that case, study the code in this file and build your own `CommandLineInterface` instance. It's not too complicated. )unicode_literals)Buffer AcceptAction)Document)DEFAULT_BUFFER SEARCH_BUFFER EditingMode)IsDoneHasFocusRendererHeightIsKnownto_simple_filter to_cli_filter Condition)InMemoryHistory)CommandLineInterface Application AbortAction)load_key_bindings_for_prompt)Registry)Keys)WindowHSplitFloatContainerFloat)ConditionalContainer) BufferControlTokenListControl)LayoutDimension) PygmentsLexer) PromptMarginConditionalMargin)CompletionsMenuMultiColumnCompletionsMenu)PasswordProcessorConditionalProcessorAppendAutoSuggestionHighlightSearchProcessorHighlightSelectionProcessorDisplayMultipleCursors) DefaultPrompt)Char)ValidationToolbar SystemToolbar ArgToolbar SearchToolbar)explode_tokens) print_tokens) DEFAULT_STYLEStylestyle_from_dict)Token)is_conemu_ansi is_windows DummyContext) text_typeexec_PY2N)Lexer)r4) Win32Output) ConEmuOutput) Vt100_Output) create_eventloop create_outputcreate_prompt_layoutcreate_prompt_applicationprompt prompt_asynccreate_confirm_applicationrun_applicationconfirmr2clearTcTtrddlm}|||Sddlm}||S)z Create and return an :class:`~prompt_toolkit.eventloop.base.EventLoop` instance for a :class:`~prompt_toolkit.interface.CommandLineInterface`. r)Win32EventLoop) inputhookrecognize_paste)PosixEventLoop)rM)r8prompt_toolkit.eventloop.win32rLprompt_toolkit.eventloop.posixrO)rMrecognize_win32_pasteLoops +lib/third_party/prompt_toolkit/shortcuts.pyrArAWs( |Ii9NOOIi((Fc4|xstj}t|}tr t r t |St |Stjjdd}tr|jd}tj||||S)aw Return an :class:`~prompt_toolkit.output.Output` instance for the command line. :param true_color: When True, use 24bit colors instead of 256 colors.
