Defining the mechanism by which text containing character attributes is constructed begins by subclassing L{CharacterAttributesMixin}. Defining how a single formatting state is to be serialized begins by subclassing L{_FormattingStateMixin}. Serializing a formatting structure is done with L{flatten}. @see: L{twisted.conch.insults.helper._FormattingState} @see: L{twisted.conch.insults.text._CharacterAttributes} @see: L{twisted.words.protocols.irc._FormattingState} @see: L{twisted.words.protocols.irc._CharacterAttributes} � )�print_function)� FancyEqMixinc @ s6 e Zd ZdZdZdd� Zdd� Zdd� Zd d d �Zd S )� _Attributea1 A text attribute. Indexing a text attribute with a C{str} or another text attribute adds that object as a child, indexing with a C{list} or C{tuple} adds the elements as children; in either case C{self} is returned. @type children: C{list} @ivar children: Child attributes. ��childrenc C s g | _ d S �Nr ��self� r �@/usr/lib/python3/dist-packages/twisted/python/_textattributes.py�__init__+ s z_Attribute.__init__c C s dt | �jt| �f S )Nz<%s %r>)�type�__name__�varsr r r r �__repr__/ s z_Attribute.__repr__c C sB t |ttttf�st�t |ttf�r2| j�|� n | j�|� | S r ) � isinstance�list�tupler �str�AssertionErrorr �extend�append)r �itemr r r � __getitem__3 s z_Attribute.__getitem__N�toVT102c C sX |dkrt � }| jD ]>}t|t�r6|�||�� |� qt||�}||� � ||� qdS )a Serialize the text attribute and its children. @param write: C{callable}, taking one C{str} argument, called to output a single text attribute at a time. @param attrs: A formatting state instance used to determine how to serialize the attribute children. @type attributeRenderer: C{str} @param attributeRenderer: Name of the method on I{attrs} that should be called to render the attributes during serialization.

The exact result of the serialization depends on the behavior of the method specified by I{attributeRenderer}. For example, if your terminal is VT102 compatible, you might run this for a colorful variation on the "hello world" theme:: from twisted.conch.insults.text import flatten, attributes as A from twisted.conch.insults.helper import CharacterAttribute print(flatten( A.normal[A.bold[A.fg.red['He'], A.fg.green['ll'], A.fg.magenta['o'], ' ', A.fg.yellow['Wo'], A.fg.blue['rl'], A.fg.cyan['d!']]], CharacterAttribute())) @param output: Object returned by accessing attributes of the module-level attributes object. @param attrs: A formatting state instance used to determine how to serialize C{output}. @type attributeRenderer: C{str} @param attributeRenderer: Name of the method on I{attrs} that should be called to render the attributes during serialization. Defaults to C{'toVT102'}. @return: A string expressing the text and display attributes specified by L{output}. r? )r r �join)�outputr r!
