from pandocfilters import toJSONFilter

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

if __name__ == "__main__":
  toJSONFilter(caps)

In the above sample,

key == 'Str' is never true as

key are values like:

  • unMeta
  • tag
  • contents

Yes, the json output produced for generics changed between aeson
0.6.1 and 0.6.2, breaking this module.

The problem is fixed if you install pandoc with the latest pandoc-types.

cabal update && cabal install --reinstall pandoc pandoc-types pandoc-citeproc

Or, if you're on Windows, grab the latest package installer.

Thanks for the quick response. I'm actually on a Mac using pandoc 1.12.0.1 which I install as a binary. Is this fixed in 1.12.0.2?

Oh, bother. You're right - the osx package is also affected.
I'll try to upload a new one today or tomorrow.

A new OSX package has been uploaded (1.12.0.2). Let me know if that fixes things.
