How do I use onepy?

onepy exposes two main classes - OneNote and ONProcess.

OneNote

OneNote is an object model class that lets you read content and hierarchy from the OneNote application. It exposes them as native python types so you can read OneNote data without having to muck around with the underlying COM interfaces.

Updating content via the object model is possible, but not implemented today.

Use OneNote to read content from notebooks:

import onepy

on = onepy.OneNote()

# print a list of notebooks open in the OneNote 2013 client
for notebook in on.hierarchy:
  print (notebook)

ONProcess

ONProcess is a thin python wrapper around the COM interfaces for the OneNote API. It simplifies starting up the process, choosing the right process when multiple versions are available and provides more pythonic interfaces for the OneNote process.

You'll need to use ONProcess to do anything outside of reading content. Read the source for onmanager.py for a list of available API calls.

For example, you can export onenote sections to PDF:

import onepy

on = onepy.OneNote()
proc = on.process

def first_section_id():
  for notebook in on.hierarchy:
    for section in notebook:
      return section.id

proc.publish(first_section_id(), "C:\\Users\<account name>\Desktop\onepy-test.pdf", 3)

Common Errors

(Office 2013) This COM object can not automate the makepy process - please run makepy manually for this object

To work around this, run regedit.exe, and navigate to

HKEY_CLASSES_ROOT\TypeLib\{0EA692EE-BB50-4E3C-AEF0-356D91732725}

There should only be one subfolder in this class called 1.1. If you see 1.0 or any other folders, you'll need to delete them. The final hierarchy should look like this:

|- {0EA692EE-BB50-4E3C-AEF0-356D91732725}
|     |- 1.1
|         |-0
|         | |- win32
|         |- FLAGDS
|         |- HELPDIR
