it happened again - François Pinard already had a fully fledged
implementation of my "new" org-mode feature: 'org-weights.el'
,--------------------------------------
| https://github.com/pinard/org-weights
`--------------------------------------
But this time I was saved from implementing a completely independent
version of the same idea (see 'outorg.el' vs 'poporg.el') but rather
forked his library on github and merged my ideas/code with his:
,------------------------------------
| https://github.com/tj64/org-weights
`------------------------------------
Although the details are still a bit buggy, the general mechanism
already works.
1. 'org-weights' works with Org-mode as well as with outshine buffers
now (including Emacs Lisp files with conventional headers (^;;;+ ). It
might even work with plain outline buffers.
2. 'org-weights' now offers to display the headline-weights (number of
subtrees and number of paragraphs) or hidden-lines-cookies (the number
of (hidden) lines till the next visible headline.
Here are a few examples (don't bother about the numbers, they are made
up, since I cannot copy overlays):
1. Org-mode/subtree-weights:
,-----------------------------------------------
| * Header 1 * 2 + 1...
| ** Header 2a ** 1
|
| text text text text text
| text text text text text
|
| ** Header 2b ** 1
`-----------------------------------------------
2. Outshine Emacs Lisp/subtree-weights:
,--------------------------------------------------
| ;; * Header 1 * 2 + 1...
| ;; ** Header 2a ** 1
|
| text text text text text
| text text text text text
|
| ;; ** Header 2b ** 1
|
`--------------------------------------------------
3. Conventional Emacs-Lisp/hidden-lines-cookies
,--------------------------------
| ;;; Header 1 [#1]
| ;;;; Header 2a [#4]
|
| text text text text text
| text text text text text
|
| ;;;; Header 2b [#2]
|
`--------------------------------
4. Outshine PicoLisp/hidden-lines-cookies
,--------------------------------
| ## * Header 1 [#1]
| ## ** Header 2a [#4]
|
| text text text text text
| text text text text text
|
| ## ** Header 2b [#2]
|
`--------------------------------
'org-weights' is implemented with overlays, so the files are not
touched. Command 'org-weights-mode' toggles activation, and
'org-weights-or-cookies' switches between subtree-weights and
hidden-lines-cookies.
Actually the hidden-lines-cookies are not really about hidden-lines
anymore in this implementation, because I adapted to the semantics of
'org-weights' that shows the overlay-info for *all* headlines except the
one where point is on.
Besides the still buggy details for outshine buffers (the calculated
numbers are not always quite right), one problem I hit is that a
visibility change does not uptdate all cookies/weights at once, they are
only updated headline per headline when point is moved up and down.
Is that for performance reasons?
