Use as preprocessor error

[shenghxie]

I was trying to use pancritic as a preprocessor for pandoc using
pancritic docum1.md -t markdown -m a | pandoc -s -o docum1.pdf
but got the following error.
I was planning to apply --filters in pandoc.
I am wondering the correct way of using it as a preprocessor.

Traceback (most recent call last):

Can you upload your docum1.md?

docum1.md is quite simple:

# Heading
{++add++}
{--remove--}
{>>comment<<}
content

~$ pancritic docum1.md -t markdown -m a | pandoc -s -o docum1.pdf

This might be related to #5. I don't get this particular error, but your error seems to have to do with processing the output_format, so it might just be related.

I just tested this case and it runs fine. But I noticed that you're using Python 2.7. Have you try using Python 3 to run that?

(In case it is really just Python 2, since Python 2 is deprecating in less than a year, I don't think it is worth spending time to fix that... Sorry, Python 2.)
