Orb-publish development branch

[myshevchuk]

This branch will be dedicated to publishing org-roam notes with an emphasis on creating annotated bibliographies. See #19.

Backend:

• org-publish and ox

Planned features:

1. A mechanism to aggregate notes into one temporary file/buffer which will be published as a single PDF file. It doesn't make much sense to publish every note as a single PDF file. Therefore 2:
2. A LaTeX template and/or an option to use a template for publishing, fine tuned for a nice one-note-per-page layout.
3. A mechanism to filter notes for publishing using subdirectories, org-roam tags, specific BibTeX fields.

Html publishing seems to be more or less useable with out-of-the-box ox, see the amazing Org Roam Server. But we would perhaps like to add some filtering and other org-roam-bibtex-specific features.
