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} � )�ClassVar�List�Sequence)� FancyEqMixinc @ sN e Zd ZU dZdZeee ed< dd� Z ed�dd�Z d d � Z dd d�Z d 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. ��children�compareAttributesc C s g | _ d S �Nr ��self� r ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/twisted/python/_textattributes.py�__init__+ s z_Attribute.__init__)�returnc C s dt | �j� dt| ��d�S )N�<� �>)�type�__name__�varsr r r r �__repr__. s z_Attribute.__repr__c C sB t |ttttf�sJ �t |ttf�r2| j�|� n | j�|� | S r )� isinstance�list�tupler �strr �extend�append)r �itemr r r � __getitem__1 s z_Attribute.__getitem__N�toVT102c C sX |du rt � }| 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}. rI )r" r �join)�outputr& r' Z flattenedr r r �flatten s "rR )rR r! rE N)r )r+ �typingr r r Ztwisted.python.utilr r r- r/ r5 r8 r= r? rE r! rJ rR �__all__r r r r �<module> s 6 ) '
