Subject: Relative performance of text-properties search functions
Date: Thu, 23 May 2013 14:16:47 +0200	[thread overview]
Message-ID: <87fvxdsxg0.fsf@gmail.com> (raw)


Hi List, 

I'm just discovering Emacs text-properties, and I wonder what would be
the right thing to do (from a performance point of view) in a case where
at the end of each outline (or org-mode) headline in a buffer a
replacing display spec should be inserted, and then updated many times
afterwards (either on user demand or via a visibility-change hook):

1. use 'outline-next-visible-heading' and 'move-end-of-line' to find the
specs and then insert/modifify them?
2. use Emacs text-properties search functions to find the specs?

I would guess its (1), but would like to reassure myself by asking this
question. 

-- 
cheers,
Thorsten
