Below are the release notes.
previous-buffercommands 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-modeis enabled in the current buffer or
pulsar-global-modeis in use).
pulsar-recenter-middleis 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-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-faceis 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 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
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)
