[hakyll] Could someone provide me an example how to use Pandoc Filter within Hakyll?

[Yun]

I am sorry to ask such question. But I am really new to Haskell. I searched
the Internet for a whole day but didn't find any example.

I have a pandoc filter written in python (`tikzcd.py`). I want to use that
filter to process my blog posts.

I guess I need to use `unixFilter` or `pandocCompileWithTransform` but my
knowledge to Haskell is really not enough to find a solution myself.

So, could someone provide me an example?

Not sure exactly, but I import some stuff from Text.Pandoc.Options in my
site.hs to change how Pandoc writes its output:

https://github.com/zeckalpha/kyle.marek-spartz.org/blob/master/site.hs#L15
https://github.com/zeckalpha/kyle.marek-spartz.org/blob/master/site.hs#L238

It may be possible to chain a filter in there somehow. Pandoc's
scripting documentation isn't too clear about how to chain filters into
readers and/or writers:

http://pandoc.org/scripting.html

Hopefully that can get you started.

Thanks for your reply!

But I have looked up Pandoc's API and didn't find out how to do this using
Options. In fact, I have already used some options as you did.

As far as I understand,

pandoc --filter foobar.py

is equivalent to

pandoc -t json | ./foobar.py | pandoc -f json

So I think I should use some `unixFilter` to do this.

I don't think it will be too hard, but I do need to learn some Haskell so
to make it easy.
