How to use stdin?

Hey guys,

I tried to use Asciidoctor as converter for my static site generator which I am implementing in python3. Since there is no wrapper module for it, I tried to call Asciidoctor via subprocess. Popen which works quite fine when I give it the filename of my sourcefile.

However I need Asciidoctor to accept a string from my program and tried to use stdin as it was shown in the documentation. Since I never got any results I played a little with the cli and discovered that even the example from the documentation does not work when I run it from bash. Am I doing something wrong since copy&paste from the docs should work (at least that is what I think ;) ).

My python function running Asciidoctor:

def generate_html(filecontent):
    command = ["asciidoctor", "-s", "-o", "-"]
    filecontent = filecontent.encode()
    with Popen(command, stdin=PIPE, stdout=PIPE) as p:
        return p.communicate(input=filecontent)[0]

I am running:

• Kubuntu 16.04.2
• Asciidoctor 1.5.5 (installed via apt)

Does anybody know of this and can me help out? If you need any further information I am happy to help.

Cheers,
Tristan
