How to create non-inheritable properties?

How to create non-inheritable properties?

[Grant Rettke]

Hi,

My org file has a lot of text in it. It really needs to be in the same
file though, so it is a big file.

When I org-babel-tangle, I would like to speed it up as it takes 8 minutes.

One thought; if I mark the headings that should neither export nor
tangle, at all, with this:

  :PROPERTIES:
  :exports: none
  :tangle: no
  :END:

Then would it be possible to make those non-overridable so that when
tangling is occurring that those huge
chunks of text would simply be ignored and possible speed up the tangle?

Kind regards,

8 minutes? wow ...

when I convert my former big init.el with 7272 lines to org-mode with

,-----------------------
| M-x outorg-edit-as-org
`-----------------------

like this

,------------------------------------------
| (benchmark-run (outorg-edit-as-org '(4)))
`------------------------------------------

the result is

,-----------------------------------
| (3.551239904 8 0.7361492030000001)
`-----------------------------------

i.e. 4 seconds.

Converting it back to emacs-lisp-mode with

,---------------------------------------------
| (benchmark-run (outorg-copy-edits-and-exit))
`---------------------------------------------

takes 

,------------------------------------
| (0.107002176 1 0.09775636400000032)
`------------------------------------

i.e. 0.1 sec.

I don't know *how* big your file is, but instead of waiting 8 min for
tangling you could as well install outshine.el and outorg.el and then
use

,-----------------------------------
| M-: outorg-convert-org-to-outshine
`-----------------------------------

to convert your org-file to an (org-style) structured emacs-lisp
file. Then you don't need any tangling anymore since you are in
emacs-lisp-mode anyway, and whenever you want to edit (comment-)text you
use outorg to temporarily convert the subtree or the whole buffer to
org-mode for editing.

Just guessing at this, but ...

I suspect Grant's file has noweb chunks and that 
`org-babel-use-quick-and-dirty-noweb-expansion' is set to nil.

If the :noweb-ref feature is not used, setting that variable to t will
make a time difference of a couple of orders of magnitude.

HTH,

Chuck

Exactly. Have been using it quite extensively.

Good to be reminded.

I've relied quite heavily upon the noweb-ref property inheritance.

Glad to know at least that this is expected.

Interesting, thanks!
