Stan tags allow you to build XML documents using Python. Stan is a DOM, or Document Object Model, implemented using basic Python types and functions called "flatteners". A flattener is a function that knows how to turn an object of a specific type into something that is closer to an HTML string. Stan differs from the W3C DOM by not being as cumbersome and heavy weight. Since the object model is built using simple python types such as lists, strings, and dictionaries, the API is simpler and constructing a DOM less cumbersome. @var voidElements: the names of HTML 'U{void elements<http://www.whatwg.org/specs/web-apps/current-work/multipage/syntax.html#void-elements>}'; those which can't have contents and can therefore be self-closing in the output. � )� iscoroutine� isgenerator)� TYPE_CHECKING�Dict�List�Optional�Union)�warnN)� FlattenableFT)�hash�eq� auto_attribsc @ s~ e Zd ZU dZeed< ejded�Z e d ed< dZ e d ed < dZ e e ed < dZe e ed < dZe e ed < dS ) �slotz4 Marker for markup insertion in a template. �nameF)�init�factory�Tag�childrenNr �default�filename� lineNumber� columnNumber)�__name__� __module__� __qualname__�__doc__�str�__annotations__�attr�ib�listr r r r r r �intr � r" r" �3/usr/lib/python3/dist-packages/twisted/web/_stan.pyr # s r )r r �reprr c @ s& e Zd ZU dZeeef ed< ej e d�Z e eeef df ed< ej e d�Zed ed< dZee ed< dZee ed < dZee ed < dZee ed < ej d dd �Zee edf ed< d!dd�Zd"dd�Zdddeddfdd�Zd#dedd fdd �Zd$d d �Z defd d �Z dS )%r a^ A L{Tag} represents an XML tags with a tag name, attributes, and children. A L{Tag} can be constructed using the special L{twisted.web.template.tags} object, or it may be constructed directly with a tag name. L{Tag}s have a special method, C{__call__}, which makes representing trees of XML natural using pure python syntax. �tagName)r r � attributesr N�renderr r r F)r r �slotData�slots�returnc K s | j du ri | _ | j �|� | S )a@ Remember the slots provided at this position in the DOM. During the rendering of children of this node, slots with names in C{slots} will be rendered as their corresponding values. @return: C{self}.

This is implemented using __call__ because it then allows the natural syntax:: table(tr1, tr2, width="100%", height="50%", border="1") Children may be other tag instances, strings, functions, or any other object which has a registered flatten. Attributes may be 'transparent' tag instances (so that C{a(href=transparent(data="foo", render=myhrefrenderer))} works), strings, functions, or any other object which has a registered flattener. If the attribute is a python keyword, such as 'class', you can add an underscore to the name, like 'class_'. There is one special keyword argument, 'render', which will be used as the name of the renderer and saved as the 'render' attribute of this instance, rather than the DOM 'render' attribute in the attributes dictionary. ����_Nr' z.Value for "render" attribute must be str, got )r �extend�items� isinstancer � TypeErrorr' r& )r, r r. �k�vr" r" r# �__call__� s � z Tag.__call__�obj�deepc sf t |d�r |�� �S t|ttf�r� �fdd�|D �S t|�r&tdt� |S t|�r1tdt� |S |S )a� Clone a C{Flattenable} object; used by L{Tag.clone}.
