Version 0.2.4 of package Pulsar has just been released in GNU ELPA. You can now find it in M-x package-list RET.
Pulsar describes itself as: Pulse highlight on demand or after select functions More at https://elpa.gnu.org/packages/pulsar.html Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━━━━ CHANGE LOG OF PULSAR.EL ━━━━━━━━━━━━━━━━━━━━━━━━━ This document contains the release notes for each tagged commit on the project's main git repository: <https://gitlab.com/protesilaos/pulsar>. The newest release is at the top. For further details, please consult the manual: <https://protesilaos.com/emacs/pulsar>. Version 0.2.0 on 2022-03-16 ═══════════════════════════ ⁃ Fixed an inconsistency that was present when Emacs was running in a server-client model where the highlight would never pulse but instead remain fixed in place until another command was invoked. By default, the pulse effect should now work for that use-case. Thanks to Mark Barton, Petter Storvik, and user kb for their feedback in issue 1: <https://gitlab.com/protesilaos/pulsar/-/issues/1>. ⁃ Implemented the `pulsar-highlight-line' command and abstracted the relevant code. Unlike `pulsar-pulse-line', it never pulses the current line. Instead it keeps the highlight in place until another command is invoked. Thanks to Mark Barton for proposing this in issue 1. ⁃ Introduced the user option `pulsar-pulse' which determines whether pulsar should use a pulse effect (notwithstanding the aforementioned new command). When its value is non-nil (the default) pulsing takes place. Thanks to Petter Storvik for suggesting this approach in issue 1. ⁃ Added the user option `pulsar-iterations' which controls how smooth or abrupt the pulse effect is. This complements the existing variable `pulsar-delay'. Both apply only when `pulsar-pulse' is non-nil. ⁃ Wrote the `pulsar-generic' face and made it the default value of the `pulsar-face' user option. This is consistent with the original design of a theme-agnostic presentation, though now it ensures that the `:extend' attribute is used to stretch the highlight to the edge of the window (without it and depending on the theme, the highlight would only reach the last character on the line). ⁃ Updated the manual to reflect those changes. Version 0.1.0 on 2022-03-14 ═══════════════════════════ Initial release of the package. Please read the manual. The core idea for this package was implemented in the `prot-pulse.el' file that is part of [my dotfiles] (now deprecated). I was using it at least since December 2020.
