Hi Sullivan,

I'd like to process agenda headlines and apply face (color) to ones

It seems like I should add a function to org-finalize-agenda-hook.
When that hook is invoked, how do I iterate over agenda headlines?
I thought I could use org-map-entries, on the current buffer, as
follows:
(add-hook 'org-finalize-agenda-hook
(lambda ()
(message "starting agenda-hook")
(org-map-entries
'(message "hi")
"+highlight" nil)))
But I never get "hi" despite there being agenda items with the
"highlight" tag.
mapping entries only works in org-mode buffers, not in the agenda.
You need to do a regexp search, like this (untested):
(add-hook 'org-finalize-agenda-hook
(lambda ()
(goto-char (point-min))
(while (re-search-forward ":MYSPECIALTAG:" nil t)
(add-text-properties (point-at-bol) (point-at-eol)
'(face my-special-face)))))
or you can use forward-line to iterate over lines and then look at the
text properties
to find the tags you are looking for.
Also, I'd recommend to put a named function into the hook - makes it
easier to change it during testing without putting a large
number of bad lambdas into that hook.
Hope this helps
- Carsten
