Automatic tangling/detangling

Automatic tangling/detangling

[Matthew Bauer]

Is there any good way to automatically tangle Org files and detangle tangled files? I frequently use this workflow but they often get out of sync. I have tried adding an after-save-hook but it’s too slow to be useful. Something like auto revert mode might work better...

Anyone have solutions for this?

Hi Matthew,

How do you do the untangling? I have been using an after-hook call to org-babel-tangle, which works quite well. It is a bit slow for large files with many code segments (like my Emacs init file at https://github.com/zzamboni/dot-emacs/blob/master/init.org <https://github.com/zzamboni/dot-emacs/blob/master/init.org>), and it requires a bit of discipline for editing only the org file and not the output file, but works well otherwise. I have never tried to de-tangle, that would require some markers in the output file I guess?

Here’s the code I use at the moment I am super happy with it, as it prevents my output files to get out of sync from the org file:

(add-hook 'org-mode-hook
          (lambda () (add-hook 'after-save-hook 'org-babel-tangle
                               'run-at-end 'only-in-org-mode)))

Best,
—Diego

Yes, detangling works okay for me. I just setup properties like this:

* Emacs Init file
:PROPERTIES:
:header-args: :tangle yes :comments link
:END:

...etc.

And you can open the generated file and run "org-babel-detangle" when
you are done editing it.

I guess I'm interesting in finding some "smarter" ways to do this.
Using 'append' might work better than what I have. I'm also looking in
to doing some sort of "async" usage (using some checks so multiple
tangles don't run at once).

I wonder if there's an easy way to setup "locks" in Emacs so you can
only edit one file at a time (kind of like how auto revert works).
Still researching all of this.

Interesting! I didn’t know about org-babel-detangle. I’d be very interested in what you come up with. I’ll try to do some exploration on my own as well.
