Subject: patch to outline.el concerning isearch
Date: Wed, 13 Dec 2006 22:53:11 -0500 [thread overview]
Message-ID: <87bqm7yvyw.fsf@earthlink.net> (raw)

Hello,
I want to implement a particular feature in org-mode that depends upon some
functionality being added to outline-mode. (org-mode is derived from
outline-mode.) The feature concerns display of ancestor and sibling headings
when an isearch has come to successful completion in a hidden part of the
file. The function whose job it is to decide what to display when an isearch
has completed is called `outline-isearch-open-invisible'. Currently, it
simply calls `(show-entry)'. The following patch changes that function, and
adds a new variable, to allow derived modes or motivated users to implement
alternate behavior. The default behavior remains the same, but can more
easily be reprogrammed by a derived mode.
Please comment, criticize, or enlighten. Thank you,
John Foerch
