[novoid]

Hi,

At least in #1 you mentioned positive effects in sharing code with https://github.com/novoid/Memacs

In the recent days, I've been busy migrating https://github.com/novoid/orgformat to a repository on its own. I've added good documentation, valuable unit tests to all functions and even added type annotations to the library itself (playing around with mypy which I recommend).

You may find some of the functions interesting for your project and I'm happy to receive pull requests of functions that you'll move out from your project to this general purpose Org mode library as well - if this is something you are thinking about.
