What it says in the title.

Hi - thanks for this project.

However, one thing that this lacks right now is support for promises being returned from the action method. Given the async nature in node, this is almost mandatory. I've looked at the tests and they don't have an example either.

Would also be awesome to have an example/test showing async callback code in action - say for example the abc.py sample from the python pandoc filters repo.

I don't know enough about JavaScript to know whether this is the same issue as #1 (though I suspect it is), but let me describe it anyway :-)

All the examples end with pandoc.stdio(action) where action is a function like:

function action(type, value, format, meta) {
    // ...
    return something;
}

In my case, inside action I need to call a function that takes a callback (as is typical for Node):

function action(type, value, format, meta) {
    // ...
   doAsync(value, function () { ... });
}

So I won't have something to return from inside action.

I am right now trying to hack it out by copying and editing much of the internals of pandoc-filter.
(Specifically, stdio which is an alias for toJSONFilter calls filter which calls walk and it appears I need to hack a copy of that function: https://github.com/mvhenderson/pandoc-filter-node/blob/be9d69ac/index.js#L47,L79 .)

But I imagine this is a common use case, and it would be better if pandoc-filter supported this.

Pandoc 3 introduces Figure type, but this library doesn't seem to support it.

• https://github.com/jgm/pandoc-types/blob/1.23/src/Text/Pandoc/Definition.hs#L304-L305

I'm using this package and while trawling through the pandoc repository I noticed that the next version of pandoc will alter the JSON output.

It looks like the python pandocfilters project already supports the change, so I just thought I'd raise it here too.
