Requests with the same filename will get the same module, with its namespace cleared. ``modname`` should be the module name - normally either '__main__' or the basename of the file without the extension. When scripts are executed via %run, we must keep a reference to their __main__ module around so that Python doesn't clear it, rendering references to module globals useless. This method keeps said reference in a private dict, keyed by the absolute path of the script. This way, for multiple executions of the same script we only keep one copy of the namespace (the last one), thus preventing memory leaks from old references while allowing the objects from the last execution to be accessible. z(Module created for script run in IPython��docc S s dS �NTr r r r r r$ M r� z/InteractiveShell.new_main_mod.<locals>.<lambda>) r� r �abspath�_main_mod_cache�KeyErrorr{ � ModuleTyper2 �clearr �__file__� __nonzero__)r �filename�modnameZmain_modr r r � new_main_mod+ s � z InteractiveShell.new_main_modc C s | j �� dS )a� Clear the cache of main modules.

When IPython is started normally, both parameters are None: a new module is created automatically, and its __dict__ used as the namespace. If only user_module is provided, its __dict__ is used as the namespace. If only user_ns is provided, a dummy module is created, and user_ns becomes the global namespace. If both are provided (as they may be when embedding), user_ns is the local namespace, and user_module provides the global namespace. Parameters ---------- user_module : module, optional The current user module in which IPython is being run. If None, a clean module will be created. user_ns : dict, optional A namespace in which to run interactive commands. Returns ------- A tuple of user_module and user_ns, each properly initialised.

Parameters ---------- exc_tuple : tuple of exception classes A *tuple* of exception classes, for which to call the defined handler. It is very important that you use a tuple, and NOT A LIST here, because of the way Python's except statement works. If you only want to trap a single exception, use a singleton tuple:: exc_tuple == (MyCustomException,) handler : callable handler must have the following signature:: def my_handler(self, etype, value, tb, tb_offset=None): ... return structured_traceback Your handler must return a structured traceback (a list of strings), or None. This will be made into an instance method (via types.MethodType) of IPython itself, and it will be called if any of the exceptions listed in the exc_tuple are caught. If the handler is None, an internal basic one is used, which just prints basic info. To protect IPython from crashes, if your handler ever raises an exception or returns an invalid result, it will be immediately disabled. Notes ----- WARNING: by putting in your own exception handler into IPython's main execution loop, you run a very good chance of nasty crashes. This facility should only be used if you really know what you are doing. z/The custom exceptions must be given as a tuple.Nc S s* t d� t d|� t d|� t d|� d S )Nz'*** Simple custom exception handler ***zException type :zException value:zTraceback :)r} )r �etyper �tbr r r r � dummy_handler� s z6InteractiveShell.set_custom_exc.<locals>.dummy_handlerc S sV d| }| du rg S t | t�r$| gS t | t�s6t|��| D ]}t |t�s:t|��q:| S )a? validate structured traceback return type return type of CustomTB *should* be a list of strings, but allow single strings or None, which are harmless.

GUI frameworks like wxPython trap exceptions and call sys.excepthook themselves. I guess this is a feature that enables them to keep running after exceptions that would otherwise kill their mainloop. This is a bother for IPython which expects to catch all of the program exceptions with a try: except: statement. Normally, IPython sets sys.excepthook to a CrashHandler instance, so if any app directly invokes sys.excepthook, it will look to the user like IPython crashed. In order to work around this, we can disable the CrashHandler and replace it with this excepthook instead, which prints a regular traceback using our InteractiveTB. In this fashion, apps which call sys.excepthook will generate a regular-looking exception from IPython, and the CrashHandler will only be triggered by real IPython crashes. This hook should be used sparingly, only in places which are not likely to be true IPython errors. r r# N)� showtraceback)r r r r r r r r` � s zInteractiveShell.excepthookc C sv |du rt �� \}}}n |\}}}|du rJtt d�rJt jt jt j }}}|du rZtd��|t _|t _|t _|||fS )z�get exc_info from a given tuple, sys.exc_info() or sys.last_type etc. Ensures sys.last_type,value,traceback hold the exc_info we found, from whichever source. raises ValueError if none of these contain any information N� last_typezNo exception to find)r r& r� r. � last_valuer� rz )r r, r r r r r r � _get_exc_info� s � z InteractiveShell._get_exc_infoc C s t d| tjd� dS )ztShow a short message for UsageErrors These are special exceptions that shouldn't show a traceback. zUsageError: %sr$ N)r} r r_ )r �excr r r �show_usage_error s z!InteractiveShell.show_usage_errorc C s& | � |�\}}}t�||�}d�|�S )z} Return as a string (ending with a newline) the exception that just occurred, without any traceback. r� )r0 � traceback�format_exception_onlyr� )r r, r r r r! r r r �get_exception_only" s z#InteractiveShell.get_exception_onlyc sf �z4z| � |�\}}}W n$ ty< tdtjd� Y W dS 0 t|t�rV| �||� n�|tu rj| � |� n�|r�dg} | � | j � ||�� n�� fdd�� � |�r�t �� ndz,t|d�r�|�� } n| j j||||d�} W n( t� y� td � t �� Y W dS 0 | �||| � | j�r | jd d � W dS | �||| � W n* t�y` td | � � tjd� Y n0 dS ) a Display the exception that just occurred.

Parameters ---------- text : string A string of text to be completed on. It can be given as empty and instead a line/position pair are given. In this case, the completer itself will split the line like readline does. line : string, optional The complete line that text is part of. cursor_pos : int, optional The position of the cursor on the input line. Returns ------- text : string The actual text that was completed. matches : list A sorted list with all possible completions. Notes ----- The optional arguments allow the completion to take more context into account, and are part of the low-level completion API. This is a wrapper around the completion mechanism, similar to what readline does at the command line when the TAB key is hit. By exposing it as a method, it can be used by other non-readline environments (such as GUIs) for text completion.

Static transformations, implemented in IPython.core.inputtransformer2, deal with things like ``%magic`` and ``!system`` commands. These run on all input. Dynamic transformations, for things like unescaped magics and the exit autocall, depend on the state of the interpreter. These only apply to single line inputs.

The execution mode depends on the interactivity parameter. Parameters ---------- nodelist : list A sequence of AST nodes to run. cell_name : str Will be passed to the compiler as the filename of the cell. Typically the value returned by ip.compile.cache(cell). interactivity : str 'all', 'last', 'last_expr' , 'last_expr_or_assign' or 'none', specifying which nodes should be run interactively (displaying output from expressions). 'last_expr' will run the last node interactively only if it is an expression (i.e. expressions in loops or other blocks are not displayed) 'last_expr_or_assign' will run the last expression or the last assignment. Other values for this parameter will raise a ValueError. compiler : callable A function with the same interface as the built-in compile(), to turn the AST nodes into code objects.

This turns on support for matplotlib, preloads into the interactive namespace all of numpy and pylab, and configures IPython to correctly interact with the GUI event loop. The GUI backend to be used can be optionally selected with the optional ``gui`` argument. This method only adds preloading the namespace to InteractiveShell.enable_matplotlib. Parameters ---------- gui : optional, string If given, dictates the choice of matplotlib GUI backend to use (should be one of IPython's supported backends, 'qt', 'osx', 'tk', 'gtk', 'wx' or 'inline'), otherwise we use the default chosen by matplotlib (as dictated by the matplotlib build-time options plus the user's matplotlibrc configuration file). Note that not all backends make sense in all contexts, for example a terminal ipython can't display figures inline. import_all : optional, bool, default: True Whether to do `from numpy import *` and `from pylab import *` in addition to module imports. welcome_message : deprecated This argument is ignored, no welcome message will be displayed. r )� import_pylabr� c s" g | ]}�j | � | ur|�qS r )r )rJ r� �r� r r r r� o r� z1InteractiveShell.enable_pylab.<locals>.<listcomp>) ZIPython.core.pylabtoolsr r r� � intersectionr � differencer� r� ) r r Z import_allZwelcome_messager r ZignoredZbothZ clobberedr r r � enable_pylabH s z InteractiveShell.enable_pylabc C sh | j �� }zt�|d �}W n ty.

Parameters ---------- range_str : str The set of slices is given as a string, like "~5/6-~4/2 4:8 9", since this function is for use by magic functions which get their arguments as strings. The number before the / is the session number: ~n goes n back from the current session. If empty string is given, returns history of current session without the last input. raw : bool, optional By default, the processed input is used. If this is true, the raw input history is used instead. Notes ----- Slices can be described with two notations: * ``N:M`` -> standard python form, means including items N...(M-1). * ``N-M`` -> include items N..M (closed endpoint). ��rawr� c s s | ]\}}}|V qd S r r )rJ r� �xr r r rL � r� z7InteractiveShell.extract_input_lines.<locals>.<genexpr>r� N)r� Zget_range_by_strr� �rfind)r Z range_strr0 r� rY r r r �extract_input_lines� s z$InteractiveShell.extract_input_linesc C sD | j ||d�}|r|S z |�d�r2tj||d�W S W nd ty� } zL|svddlm} ||�} | �� �d�W Y d}~S t d| �|�W Y d}~n d}~0 0 |g} z| � dt |�� W n t y� Y n0 | D ]�} t j�| ��rxztj| |d�W S t�yt } zh|�sRt| d dd ��(} | �� W d � W Y d}~ S 1 �sH0 Y t d| �|�W Y d}~n d}~0 0 q�t j�t j�| ��r�t d | ��q�|�r�| j|d d �} | d �r�| d �r�| d S zt|| j�}W n4 t�y } zt d| �|�W Y d}~n d}~0 0 t|t��r |S t|t��r2|jS t d| |��dS )aV Get a code string from history, file, url, or a string or macro. This is mainly used by magic functions. Parameters ---------- target : str A string specifying code to retrieve. This will be tried respectively as: ranges of input history (see %history for syntax), url, corresponding .py file, filename, or an expression evaluating to a string or Macro in the user namespace. If empty string is given, returns complete history of current session, without the last line. raw : bool If true (default), retrieve raw history. Has no effect on the other retrieval mechanisms. py_only : bool (default False) Only try to fetch python code, do not try alternative methods to decode file if unicode fails. Returns ------- A string of code. ValueError is raised if nothing is found, and TypeError if it evaluates to an object of another type.
