Hi Folks,
Is there a function to extract the body of an item minus all the
auxiliary information?
* Item
This is the text I want.
And here is the second line.
SCHEDULED: <2012-05-12>
DEADLINE: <2012-05-13>
:PROPERTIES:
:foo: bar
:END:
And it's conceivable there is more below drawers...
** Sub-Item 1
** Sub-Item 2
Basically I want a function that does the following:
(org-entry-get-text)
"This is the text I want
And here is the second line.
And it's conceivable there is more below drawers..."
Point is at "* Item" when this is called.
For one project (org-toodledo), I coded a version (see below) that pulls
out the drawers, drops properties SCHEDULED/DEADLINE/CLOSED, and pulls
off any indentation, and it works pretty well, although it is probably
not complete for all cases. However, I'm now working on extensions for
another project (org-taskjuggler) and want to again pull out the note.
I tried again to find such a function in the org source files, but I
just can't seem to find it.
Does it exist? If not, does it make sense to make my version below
workable for org-mode developers in general?
(Related, what is the right term for this block of text? Note?
Content? Text?)
Thanks
