Inline filters

[cmahnke]

Currently passing filters works by passing a list, this feels a bit clunky / sub optimal integrated...
Considering there is a package as pandocfilters, it should be possible to so something like this:

import pypandoc
from pathlib import Path
from pandocfilters import toJSONFilter, Str

def caps(key, value, format, meta):
  if key == 'Str':
    return Str(value.upper())

input = Path('somefile.md')
output = input.with_suffix('.docx')
pypandoc.convert_file(input, 'docx', outputfile=output, filters=[toJSONFilter(caps)])

(Pseudo code to illustrate how it might work. Copy and pasted from provided examples)

Or in short: It should be possible to pass a function or maybe a object as filter, while passing a string would work as it currently is

I do like that suggestion, as long as we stay backwards compatible. I'll look at it soon, unless you or someone else wants to make a pr for it.

Hi again.
So after looking into it, it seems that this doesn't seem to be quite possible, considering that "toJSONFilter" doesn't actually return, but just reads from stdin and writes to stdout right away.
