The documentation furnished herein corresponds to stable version 1.3.0, released on 2025-11-30. 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 1.4.0-dev. ## Recent NEWS: ━━━━━━━━━━━━━━━━━━━━━━━━━ CHANGE LOG OF PULSAR.EL ━━━━━━━━━━━━━━━━━━━━━━━━━ The newest release is at the top.

Table of Contents ───────────────── Version 1.3.0 on 2025-11-30 Version 1.2.0 on 2024-12-12 Version 1.3.0 on 2025-11-30 ═══════════════════════════ This version introduces a new feature and makes small refinements to an already reliable base. Permanent static highlight for a line or region ─────────────────────────────────────────────── In the most common use-case, Pulsar produces a highlight that fades in and out of view after a certain amount of time. The idea with such a "pulse effect" is to quickly get a sense of where the cursor is when some change occurs (e.g. switching to another window). The permanent static highlights differ from pulse effects in two ways: (i) they do not have a fade-in and fade-out phase and (ii) are not removed automatically. These highlights stick around either until the user removes them or their underlying text is deleted. They are meant to be used as intentional highlights, such as to draw attention to a certain statement while doing a presentation. The command `pulsar-highlight-permanently' adds a permanent static highlight to the current line. When the region is active, the highlight is applied from the beginning to the end of the region. The command `pulsar-highlight-permanently-remove' removes permanent static highlights from the active region or current line. This command operates on the entire buffer when it is called with a universal prefix argument (`C-u' by default). The command `pulsar-highlight-permanently-dwim' adds a permanent static highlight if there is none or removes it if there is one. It operates on the currently active region or line at point. Permanent static highlights are rendered with the face specified in the user option `pulsar-highlight-face'. New name for temporary static highlights ──────────────────────────────────────── The commands `pulsar-highlight-dwim' and `pulsar-highlight-line' are obsolete aliases for `pulsar-highlight-temporarily'. Temporary static highlights do not have a fade-in and fade-out phase. They are automatically removed as soon as an action occurs. They are an alternative to the aforementioned permanent static highlights. The command `pulsar-highlight-temporarily' will operate on the active region or the current line. Miscellaneous ───────────── • Thanks to Koloszár Gergely for reporting an intermediate bug where the pulse effect actually did not pulse under certain conditions. This was done in issue 31: <https://github.com/protesilaos/pulsar/issues/31>. • Parts of the code are rewritten in the interest of clarity. • The entire manual is redone to better organise the documentation. Version 1.2.0 on 2024-12-12 ═══════════════════════════ This version refines an already stable base. Users do not need to make any changes to their setup, unless they wish to try the new features. Automatically pulse the affected region ─────────────────────────────────────── With the out-of-the-box settings, Pulsar temporarily highlights the current line after any of the `pulsar-pulse-functions' is invoked and `pulsar-mode' (or `pulsar-global-mode') is enabled. The new user option `pulsar-pulse-region-functions' makes Pulsar temporarily highlight the affected region as well. For example, when pasting some text into the buffer, it will highlight the portion of text that was added. The default value of `pulsar-pulse-region-functions' is nil, meaning that no region pulsing is in effect (what we had before). Otherwise, it is a list of functions. A typical use-case is the following: … …
