Provides classes for handling Python source input and arbitrary output interactively from a Twisted application. Also included is syntax coloring code with support for VT102 terminals, control code handling (^C, ^D, ^Q), and reasonable handling of Deferreds. @author: Jp Calderone � N)�BytesIO)�recvline)�defer)�_get_async_param)� TokenPrinterc @ s8 e Zd ZdZdZdZdd� Zdd� Zdd � Zd d � Z d S ) � FileWrapperz� Minimal write-file-like object.

Aside from the features provided by L{code.InteractiveInterpreter}, this class captures sys.stdout output and redirects it to the appropriate location (the Manhole protocol instance). It also treats Deferreds which reach the top-level specially: each is formatted to the user with a unique identifier and a new callback and errback added to it, each of which will format the unique identifier and the result with which the Deferred fires and then pass it on to the next participant in the callback chain. r N� <console>c C s, t j�| |� i | _|| _|| _| �� d S r )�code�InteractiveInterpreterr �_pendingDeferreds�handler�filename� resetBuffer)r r$ �localsr% r r r r C s zManholeInterpreter.__init__c C s g | _ dS )z) Reset the input buffer.

The line should not have a trailing newline; it may have internal newlines. The line is appended to a buffer and the interpreter's runsource() method is called with the concatenated contents of the buffer as source. If this indicates that the command was executed or invalid, the buffer is reset; otherwise, the command is incomplete, and the buffer is left as it was after the line was appended. The return value is 1 if more input is required, 0 if the line was dealt with in some way (this is the same as runsource()). @param line: line of text @type line: L{bytes} @return: L{bool} from L{code.InteractiveInterpreter.runsource} � �utf-8)r( �appendr �decodeZ runsourcer% r& )r �line�source�morer r r �pushP s zManholeInterpreter.pushc O sj t j| j }t _zLt jt| j� }t _z$tjj| g|�R i |�� W |t _n|t _0 W |t _n|t _0 d S r )�sys� displayhook�stdoutr r$ r! r" �runcode)r �a�kwZorighookZorigoutr r r r4 j s zManholeInterpreter.runcodec C s� || j d< t|tj�r�t|d�r0| �t|�� q�t|�| jv r^| �d| jt|� d f � q�| j}| j }||f|t|�< | j d7 _ |j | j | j ||f||fd� | �d|f � n|d ur�| �t|�� d S )N�_�resultz<Deferred #%d>r � )Z callbackArgsZ errbackArgs) r' � isinstancer ZDeferred�hasattrr �repr�idr# � numDeferredsZ addCallbacks�_cbDisplayDeferred�_ebDisplayDeferred)r �obj�d�kr r r r2 u s& �z ManholeInterpreter.displayhookc C s$ | � d||f d� | jt|�= |S )Nz Deferred #%d called back: %rT)r r# r= )r r8 rC rA r r r r? � s z%ManholeInterpreter._cbDisplayDeferredc C s( | � d||�� f d� | jt|�= |S )NzDeferred #%d failed: %rT)r ZgetErrorMessager# r= )r ZfailurerC rA r r r r@ � s z%ManholeInterpreter._ebDisplayDeferredc K s" t |fi |��}| j�||� d S r )r r$ r )r r �isAsync�kwargsr r r r � s zManholeInterpreter.write)Nr )N) r r r r r> r r& r0 r4 r2 r? r@ r r r r r r 3 s r � � � � � � c @ s` e Zd ZdZdZddd�Zdd� Zdd� Zd d � Zd d � Z d d� Z dd� Z ddd�Z dd� Z dS )�Manholea� Mediator between a fancy line source and an interactive interpreter. This accepts lines from its transport and passes them on to a L{ManholeInterpreter}. Control commands (^C, ^D, ^\) are also handled with something approximating their normal terminal-mode behavior. It can optionally be constructed with a dict which will be used as the local namespace for any code executed.
