Hoi,
What's the best way to process (ideally using the org-element API) a collection of .org files as one larger file?
I'm using Org + ox-reveal to write the course material for a three month course. This is a lot of material, so keeping it in one Org file is not practical (exporting it to the slides takes longer, it's easier to have multiple buffers open and switch between them, etc).
To help ensure that I'm covering the content in a sensible order I've given each heading optional TOPIC and REQUIREMENTS properties. When a new topic is introduced I add an identifier to the TOPIC property to the heading that introduces it, and if a heading requires that a topic or topics have been introduced I add the topic identifiers as a space-separated string to the REQUIREMENTS property.
I have a small function that uses the org-element API to iterate over all the headings in a file and tell if if I have any headings that list a requirement without that requirement appearing in a TOPIC property earlier in the file.
This works when the file is self contained.
When I have topics that might be introduced in one file, and later referenced in a second file, it obviously doesn't.
I thought one approach would be to have a master Org file that references all the others, so
course.org that looks like:
...
However, org-element-parse-buffer doesn't recurse in to the included files, so this doesn't work.
I could write my own function to create the recursive expansion of all the content, but before I do that I thought I'd check to see if there's a better way of doing what I'm trying to achieve.
Any ideas?
