Version 1.0.1 of package Pulsar has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Pulsar describes itself as: =================================================== Pulse highlight on demand or after select functions =================================================== More at https://elpa.gnu.org/packages/pulsar.html ## Summary: ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PULSAR.EL: PULSE HIGHLIGHT LINE ON DEMAND OR AFTER RUNNING SELECT FUNCTIONS Protesilaos Stavrou i...@protesilaos.com ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This manual, written by Protesilaos Stavrou, describes the customization options for `pulsar' (or `pulsar.el'), and provides every other piece of information pertinent to it. The documentation furnished herein corresponds to stable version 1.0.0, released on 2023-08-12. Any reference to a newer feature which does not yet form part of the latest tagged commit, is explicitly marked as such. Current development target is 1.1.0-dev. ## Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━━━━ CHANGE LOG OF PULSAR.EL ━━━━━━━━━━━━━━━━━━━━━━━━━ The newest release is at the top. For further details, please consult the manual: <https://protesilaos.com/emacs/pulsar>. Version 1.0.0 on 2023-08-12 ═══════════════════════════ • The `next-buffer' and `previous-buffer' commands are added to the default value of the user option `pulsar-pulse-functions'. They will now trigger a pulse effect after they are called (if `pulsar-mode' is enabled in the current buffer or `pulsar-global-mode' is in use). • The command `pulsar-recenter-middle' is now an alias for `pulsar-recenter-center', instead of being the original name. Users do not need to change anything on their end: this is just an internal arrangement to use a name that corresponds to the one of the underlying "recenter" mechanism. • The Lisp macro that was used to derive the Pulsar "recenter" commands has been removed. The commands are `pulsar-recenter-top' and `pulsar-recenter-center'. I originally thought the macro would be useful in more places, but I ended up relying on it only twice. Thanks to Ryan Kaskel for pointing out an intermediate typo/error I made while redefining the macro and before I decided to remove it altogether. This was done as a comment on the GitHub mirror: <https://github.com/protesilaos/pulsar/commit/c5086de779a0226d72eca4d5cba8c7689bc278b2#r123397272>. • The Lisp macro `pulsar-pulse-with-face' is renamed to `pulsar-define-pulse-with-face'. Its definition is updated to simplify how a Pulsar function is defined with a given face. Examples of such functions are `pulsar-pulse-line-red', `pulsar-pulse-line-blue'. • Pulsar now retrieves the absolute beginning of the minibuffer prompt. This means that a pulse in the minibuffer will cover the text of the prompt, as opposed to only affecting the input area. As such, the pulse is visible even if the minibuffer is empty (e.g. what happens with the default completion setup when calling `M-x'). • The manual provides instructions on how to set up Pulsar to produce a pulse when the minibuffer is activated. It cannot be done with the `pulsar-pulse-functions', though the setup is not too involved. In short: ┌──── │ (add-hook 'minibuffer-setup-hook #'pulsar-pulse-line) │ │ ;; OR something like this, replacing "blue" with one among red, │ ;; green, yellow, magenta, cyan: │ (add-hook 'minibuffer-setup-hook #'pulsar-pulse-line-blue) └──── Version 0.5.0 on 2022-08-19 ═══════════════════════════ ⁃ Added convenience functions/commands to pulse a line using one of the provided faces. These can be used interactively or via Lisp (e.g. be assigned to a hook). They are: • `pulsar-pulse-line-red' • `pulsar-pulse-line-green' • `pulsar-pulse-line-yellow' • `pulsar-pulse-line-blue' • `pulsar-pulse-line-magenta' • `pulsar-pulse-line-cyan' ⁃ Deprecated `pulsar-pulse-on-window-change' due to complications it created in some edge cases. Part of this effort was to fix a bug that pertained to a duplicate pulse when the pulsar commands were invoked via `M-x'. The duplication had the effect of potentially overriding the color of the pulse such as if, say, `pulsar-pulse-line-red' was invoked while the `pulsar-face' was blue. ⁃ Restored several command symbols to the default value of `pulsar-pulse-functions'. Those were disabled to support the use option `pulsar-pulse-on-window-change', but as that is now removed we revert to the old and more predictable way of handling things. ⁃ Introduced conditionality that checks for `real-this-command'. This is necessary for commands that have to fudge `this-command' to provide their functionality. Such is the case with the `evil-scroll-up' and `evil-scroll-down' commands which are internally reported as … …
