Walk all blocks except inside footnotes

Walk all blocks except inside footnotes

Hi,

I am using Text.Pandoc.Walk to transform all blocks of a certain type. This
works great, except that it recurses into blocks contained inside footnotes
and also applies the transformation there, which is not what I want.

What I would like is a way to stop the recursion at footnotes to prevent
them from being transformed, as I have (to the best of my knowledge) no way
to tell that a block is inside a footnote when I'm looking at it. However,
I am struggling to do this within the structure of Text.Pandoc.Walk because
the function provides no mechanisms to direct or abort recursion, and even
if it did, the footnotes themselves are inlines, not blocks.

I know I could write the traversal by hand in Haskell, but is time
consuming and would require much more code. Is there a better alternative?

Thanks in advance.

Have you looked at regular syb generics?
Data.Generic.Schemes has some functions that look
like good candidates, such as everywhereBut.
