Hi.
I'm trying to improve the aafig_ Sphinx extension to use an image node
to output the aafigure_ generated image, so it can take advantage of the
extra image options (like height, width, etc.) and any bug-fixes.
Consistency is a nice advantage too.
The problem is I'm getting an error when doing that. I'm sorry about the
cross-posting, but I don't know if the error is docutils or Sphinx
related.
What I'm doing is something like::
def aafig_node_html_visit(self, node):
# generate the aafigure image
node.img = nodes.image()
# copy aafig attributes to the image node
self.visit_image(node.img)
raise nodes.SkipNode
def aafig_node_html_depart(self, node):
self.depart_image(node.img)
raise nodes.SkipNode
I don't really know if it's ok to skip the node (I just had another error
without the raise nodes.SkipNode).
The error I'm getting is::
Traceback (most recent call last):

line 712, in depart_document

AssertionError: len(context) = 15
I'm doing something wrong? Any ideas how to do that? I can't "emit" an
image node at "parse-time" because I don't know yet what builder will be
used to pick the right output format for aafig.
TIA.
