** Changes to hideshow.el
Hideshow is now at version 5.x. It uses a new algorithms for block
selection and traversal and includes more isearch support.
*** Generalized block selection and traversal
A block is now recognized by three things: its start and end regexps
(both strings), and a match-data selector (an integer) specifying
which sub-expression in the start regexp serves as the place where a
`forward-sexp'-like function can operate. Hideshow always adjusts
point to this sub-expression before calling `hs-forward-sexp-func'
(which for most modes evaluates to `forward-sexp').
If the match-data selector is not specified, it defaults to zero,
i.e., the entire start regexp is valid, w/ no prefix. This is
backwards compatible with previous versions of hideshow. Please see
the docstring for variable `hs-special-modes-alist' for details.
*** Isearch support for updating mode line
During incremental search, if Hideshow minor mode is active, hidden
blocks are temporarily shown. The variable `hs-headline' records the
line at the beginning of the opened block (preceding the hidden
portion of the buffer), and the mode line is refreshed. When a block
is re-hidden, the variable is set to nil.
To show `hs-headline' in the mode line, you may wish to include
something like this in your .emacs.
(add-hook 'hs-minor-mode-hook
(lambda ()
(add-to-list 'mode-line-format 'hs-headline)))
