QUESTION
For a Markdown document I want to filter out all sections whose header titles are not in the list to_keep
. A section consists of a header and the body until the next section or the end of the document. For simplicity lets assume that the document only has level 1 headers.
When I make a simple case distinction on whether the current element has been preceeded by a header in to_keep
and do either return None
or return []
I get an error. That is, for pandoc --filter filter.py -o output.pdf input.md
I get TypeError: panflute.dump needs input of type "panflute.Doc" but received one of type "list"
(code, example file and complete error message at the end).
I use Python 3.7.4 and panflute 1.12.5 and pandoc 2.2.3.2.
QuestionIf make a more fine grained distinction on when to do return []
, it works (function action_working
). My question is, why is this more fine grained distinction neccesary? My solution seems to work, but it might well be accidental... How can I get this to work properly?
ANSWER
Answered 2020-Jul-17 at 07:04I think what happens is that panflute call the action on all elements, including the Doc
root element. If keep_current
is False
when walking the Doc
element, it will be replaced by a list. This leads to the error message you are seeing, as panflute expectes the root node to always be there.
The updated filter only acts on Header
, Para
, and BulletList
elements, so the Doc
root node will be left untouched. You'll probably want to use something more generic like isinstance(elem, Block)
instead.
An alternative approach could be to use panflute's load
and dump
elements directly: load the document into a Doc
element, manually iterate over all blocks in args
and remove all that are unwanted, then dump the resulting doc back into the output stream.
QUESTION
According to the API documentation,
one is supposed to be able to access global variables through the doc
variable somehow.
How though, is not explained.
global variables can be defined in YAML headers:

Answered 2019-Aug-17 at 16:26The first approach (putting the variable in the document) failed because the YAML block isn't closed, so the block is not read as metadata but as normal Markdown. Adding a closing ---
line after the metadata should fix that.
QUESTION
I'm using panflute to write a python filter for pandoc to convert Markdown into a Word document. Normally, pandoc converts Markdown headers into Word's built-in styles called Heading 1, Heading 2, etc. But due to the particulars of the Word template I have to use, I instead need to change all Markdown headers into corresponding custom styles in Word such that Header level 1 => Header1, level 2 => Header2, etc.
Here's a quick sample Markdown file I made to test my filter:
