* Don't quote 't' in doc stringsEli Zaretskii2024-02-101-2/+2
| | | | | * lisp/outline.el (outline-minor-mode-use-buttons): Doc fix. Patch by Arash Esbati <arash@gnu.org>. (Bug#69012)
* ; Add 2024 to copyright yearsPo Lu2024-01-021-1/+1

* * doc/emacs/text.texi (Outline Minor Mode): Add a note about value 'insert'.Juri Linkov2023-09-131-0/+3
| | | | | * lisp/outline.el (outline-minor-mode-use-buttons): Add a note and a comment about the value 'insert' (bug#65874).
* Improve outline-default-state docstringRobert Pluim2023-04-261-2/+4
| | | | | * lisp/outline.el (outline-default-state): Explain which functions are available to affect heading visibility.
* * lisp/outline.el (outline--fix-buttons-after-change): Add save-match-data.Juri Linkov2023-03-221-1/+1
| | | | | | It's important for a hook in after-change-functions not to change match-data. Otherwise it breaks functions that make changes in the buffer, such as for example, successive calls to delete-region in smerge-keep-n, etc.
* Use named keymaps for outline buttonsRobert Pluim2023-01-241-15/+18
| | | | | | | | | | | https://lists.gnu.org/archive/html/emacs-devel/2023-01/msg00334.html * lisp/outline.el (outline-button-icon-map) (outline-overlay-button-map, outline-inserted-button-map): Keymaps refactored from outline--create-button-icons and outline--insert-button. (outline--create-button-icons, outline--insert-button): Move keymaps to separate variables.
* * etc/NEWS: Mention incompatible changes in 'outline-minor-mode-cycle-map'.Juri Linkov2023-01-111-6/+16

* Fix the width of margins for icons in outline-minor-mode (bug#59719)Juri Linkov2022-12-021-10/+31
| | | | | | | | | | | | | | * doc/lispref/display.texi (Icons): Add :width spec. * lisp/emacs-lisp/icons.el (icons--create): Handle :width as well. * lisp/outline.el (outline--margin-width, outline-margin-width): New variables. (outline-open-in-margins, outline-close-in-margins) (outline-close-rtl-in-margins): Don't inherit from parents. Use `:width font' instead of `:height 10'. (outline-minor-mode): Calculate the number of columns for margins to fit the icons.
* * lisp/outline.el: 'S-<down-mouse-1>' on buffer buttons cycles all outlines.Juri Linkov2022-11-231-5/+11
| | | | | | | (outline--create-button-icons, outline--insert-button): Bind 'S-<mouse-1>' to 'outline-cycle-buffer' as it's already done for buttons on the margins. Ignore 'S-<down-mouse-1>'. Don't hard-code 'help-echo' since it should be customizable by the ':help-echo' keyword in 'define-icon'.

* * lisp/outline.el (outline-search-function): New variable (bug#53981).Juri Linkov2022-11-211-30/+128
| | | | | | | | | | | | | | | | | | | | | | (outline-font-lock-keywords, outline-font-lock-face) (outline-minor-mode-highlight-buffer, outline-next-preface) (outline-next-heading, outline-previous-heading) (outline-back-to-heading, outline-on-heading-p, outline-demote) (outline-map-region, outline-next-visible-heading) (outline-hide-sublevels, outline-up-heading): Use outline-search-function when it's non-nil as an alternative to searching outline-regexp.

* * lisp/outline.el: Use 'outline-cycle' on buttons for 'RET' like 'TAB' uses.Juri Linkov2022-10-221-10/+10
| | | | | | | | (outline--make-button-overlay, outline--make-margin-overlay): Use overlay keymap where RET and mouse-2 are bound to outline-cycle. (outline--insert-open-button, outline--insert-close-button): Move overlay keymap to outline--make-button-overlay and replace bindings outline-hide-subtree/outline-show-subtree with outline-cycle.
* Unify outline-minor-mode-use-buttons with in-margins/insert values (bug#57813)Juri Linkov2022-10-221-71/+51

(outline--insert-open-button, outline--insert-close-button) (outline--fix-up-all-buttons, outline--fix-buttons-after-change): Handle values of outline-minor-mode-use-buttons instead of using many variables.
* * lisp/outline.el (outline-minor-mode-insert-buttons): New defvar-local.Juri Linkov2022-10-181-11/+20
| | | | | | | | | | | | | | | (outline--make-button-overlay, outline--insert-open-button) (outline--insert-close-button): Insert button when outline-minor-mode-insert-buttons is non-nil, otherwise put an overlay with before-string. (bug#57813) * lisp/help.el (describe-bindings): Set buffer-local outline-minor-mode-insert-buttons to t. * lisp/textmodes/emacs-news-mode.el (emacs-news--mode-common): Set buffer-local outline-minor-mode-use-margins to t.

* Revert "keymap.el: Ease up support for non-`kbd` formats."Lars Ingebrigtsen2022-10-031-2/+1
| | | | | | | | | This reverts commit 570a11052be6178954956a1c59c8ebcbdb77d38e. We do not want to support several keymap formats in `keymap-set' and friends -- the point is to have an interface with easy-to-understand semantics that give good feedback on valid/invalid key sequences.
* keymap.el: Ease up support for non-`kbd` formats.Stefan Monnier2022-10-021-1/+2
| | | | | | | | | | | | | | While we want to standardize on the `kbd` syntax for user-facing code, the internal vector representation of key sequences is not going away, so let's not impose silly `key-description + key-parse` roundtrips. Also, provide some support for packages stuck with user configs defined to hold old-style key formats. * lisp/keymap.el (keymap-set): Allow vectors as `key`. (key-parse-old-format): New function, which stands out better than `key-description` when searching for uses of the old syntax. * list/outline.el (outline-minor-mode): Use it.
* * lisp/outline.el: More improvements for buttons/margins (bug#57813)Juri Linkov2022-09-211-12/+17
| | | | | | | | | | (outline-minor-mode-use-margins): Don't use for modes derived from help-mode that are handled by 'outline-minor-mode-use-buttons'. (outline-open, outline-close, outline-close-rtl): Use image height proportional to font height of 0.8em. (outline-minor-mode): Remove overlays 'outline-button' and 'outline-margin', and move such overlay removal after the call of 'outline-show-all' that might trigger overlay addition.
* * lisp/outline.el: Bind margin mouse event to cycle outlines (bug#57813)Juri Linkov2022-09-201-40/+42
| | | | | | | | | | | | | | | (outline-minor-mode): In mode keymap bind 'right/left-margin mouse-1' to outline-cycle, and 'right/left-margin S-mouse-1' to outline-cycle-buffer. (outline-hide-subtree, outline-show-subtree): Add save-excursion to keep point unmoved after mouse click. (outline-cycle): Add optional arg 'event' like in outline-hide-subtree and outline-show-subtree, and add save-excursion to keep point unmoved after mouse click. (outline--make-button-overlay, outline--make-margin-overlay): Put overlay property 'evaporate' to t. (outline--insert-open-button, outline--insert-close-button): Remove temporary attempts to bind margin-local mouse events.
* * lisp/outline.el (outline-open): Revert 'text' back to " open ".Juri Linkov2022-09-191-4/+3
| | | | | | (outline-close): Revert 'text' back to " close ". (outline-close-rtl): Remove 'text' since it's inherited from the parent 'outline-close'.

(outline-open, outline-close): Move :ascent center to default of define-icon. Use ASCII-art for text. Fix docstring and help-echo. (outline-close-rtl, outline-open-in-margins) (outline-close-in-margins, outline-close-rtl-in-margins): New icon definitions. (outline-minor-mode-highlight-buffer): Remove outline--insert-open-button since initial outline--fix-up-all-buttons is added now to outline-minor-mode. (outline-minor-mode): Set buffer-local outline--use-buttons, outline--use-margins and outline--use-rtl. Show/hide margins for outline--use-margins. Add hook after-change-functions for editable buffers. Move outline--fix-up-all-buttons for both cases: font-lock and non-font-lock. (outline--use-buttons-p): Remove function. (outline--make-button-overlay): Use outline--use-rtl icon outline-close-rtl. (outline--make-margin-overlay): New function. (outline--insert-open-button, outline--insert-close-button): Add optional arg 'use-margins'. (outline--fix-up-all-buttons): Call outline--insert-close-button and outline--insert-open-button with arg outline--use-margins. (outline-cycle-buffer): Remove outline--fix-up-all-buttons that is already called from outline-flag-region. * lisp/emacs-lisp/icons.el (icons--create): Handle keywords :rotation and :ascent with the default value 'center (bug#57813). * doc/emacs/text.texi (Outline Mode): Mention outline-minor-mode-use-margins.
* Support imenu in emacs-news-modeStefan Kangas2022-09-191-2/+5

* * lisp/outline.el: Optimize performance of S-TAB (bug#57813)Juri Linkov2022-09-161-10/+6
| | | | | | | | (outline-hide-subtree): Don't call outline--insert-close-button, because it's handled by outline--fix-up-all-buttons called from outline-flag-region. (outline-show-subtree): Don't call outline--insert-open-button, same reason. (outline--fix-up-all-buttons): Check invisible outlines explicitly instead of using slow outline--cycle-state.

* Fix outline-minor-mode-mapLars Ingebrigtsen2022-09-011-4/+4
| | | | | | * lisp/outline.el (outline-minor-mode): Avoid using easy-mmode-define-keymap, since it doesn't handle :inherit correctly (bug#57512).
* Fix 744ed0ceeed7472a160fea7154939cf641205577 from bug#57082 (bug#57176)Juri Linkov2022-08-301-10/+11
| | | | | | | * lisp/outline.el (outline-minor-mode-highlight-buffer): Handle 'append'. (outline-minor-mode): Call outline--fix-up-all-buttons when font-lock is used. * lisp/textmodes/emacs-news-mode.el (emacs-news--mode-common): Fix regexp.

| | | | | | | | * lisp/outline.el (outline-minor-mode-use-buttons): Change the default to only use buttons in the *Help* buffer (for now), because it's too disruptive in other modes. This will probably be changed again to have some other mechanism to opt in in certain modes, but it's not clear what that mechanism should look like.
