Include or exclude elements which depend on a specific Docutils component.
|

|
|
|
||
|
|
For use with `nodes.pending` elements. A "pending" element's dictionary
|
||
|
|
attribute ``details`` must contain the keys "component" and "format". The
|
||
|
|
value of ``details['component']`` must match the type name of the
|
||
|
|
component the elements depend on (e.g. "writer"). The value of
|
||
|
|
``details['format']`` is the name of a specific format or context of that
|
||
|
|
component (e.g. "html"). If the matching Docutils component supports that
|
||
|
|
format or context, the "pending" element is replaced by the contents of
|
||
|
|
``details['nodes']`` (a list of nodes); otherwise, the "pending" element
|
||
|
|
is removed.
|
||
|
|
|
||
|
|
For example, the reStructuredText "meta" directive creates a "pending"
|
||
|
|
element containing a "meta" element (in ``pending.details['nodes']``).
|
||
|
|
Only writers (``pending.details['component'] == 'writer'``) supporting the
|
||
|
|
"html" format (``pending.details['format'] == 'html'``) will include the
|
||
|
|
"meta" element; it will be deleted from the output of all other writers.
