When running

I get this:

pandoc: Error running filter hyphfilter.py
hyphfilter.py: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)

What am I doing wrong?

I have no clue about Python.

One method would be to rely on the CSS `hyphens` property. Unforunately,
that property is not supported by Chrome/Webkit, so an additional
polyfill library like [Hyphenator](https://github.com/mnater/Hyphenator)
would be required.

Alternatively, a pandoc filters can insert soft hyphens directly.
You'll need to install the python libraries `panflute` and `pyphen`.
Put the following code into a file and call it as a pandoc filter.


    #!/usr/bin/env python3
    from panflute import *
    import pyphen

    dic = pyphen.Pyphen(lang='en_US')

    def hyphenate(inline, doc):
        if type(inline) == Str:
            hyphenated = dic.inserted(inline.text, hyphen='­')
            return Str(hyphenated)

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


The above code uses the unicode soft hyphen instead of the HTML entity,
which helps keeping the filesize low.  Just change the `hyphen`
parameter if that's not what you want.
