Version 0.3.0 on 2022-09-04

• Implemented a mechanism to read fallback values for the presets specified in the user option cursory-presets. In practical terms, there can now be a t preset which holds the default values. Any other named preset overrides the t, so it only needs to specify the properties that differ from the defaults. Sample using the original value:

    (setq cursory-presets
          '((box
             :blink-cursor-interval 0.8)
            (box-no-blink
             :blink-cursor-mode -1)
            (bar
             :cursor-type (bar . 2)
             :blink-cursor-interval 0.5)
            (underscore
             :cursor-type (hbar . 3)
             :blink-cursor-blinks 50)
            (t ; the default values
             :cursor-type box
             :cursor-in-non-selected-windows hollow
             :blink-cursor-mode 1
             :blink-cursor-blinks 10
             :blink-cursor-interval 0.2
             :blink-cursor-delay 0.2)))
  

• Expanded the available properties of the user option cursory-presets to accept a value for the :blink-cursor-mode key (as seen in the above code block). It is either 1 or -1 and is passed to the function blink-cursor-mode. The former value enables the mode, the latter disables it. This lets cursory-presets set the blink-cursor-mode per stylistic variant.
• Refined the default value of the minibuffer prompt that is used by the command cursory-set-preset. The default value now is the previous element in the history, if it exists. This makes it easier to toggle between the last two choices (select the default value simply by pressing RET without any further input).
• Specified a :package-version for all user options. The user is informed in relevant Help buffers about the last version that introduced or iterated on the variable.
• The cursory group now references the Info manual that ships with the GNU ELPA package. A link is shown in Custom UI buffers.

Version 0.2.0 on 2022-07-01

This is a stability release that introduces minor tweaks while formalising point releases which were already available to users.

• When there is only one preset defined in the user option cursory-presets the command cursory-set-preset will not prompt for completion. It will apply the sole preset outright.

• Simplified the sample code in the manual for restoring the last preset after starting Emacs. The code is now written as follows:

    ;; Set last preset or fall back to desired style from `cursory-presets'.
    (cursory-set-preset (or (cursory-restore-latest-preset) 'bar))
  

  Thanks to Christopher League for the original idea over at the fontaine mailing list (Fontaine is another package of mine): https://lists.sr.ht/~protesilaos/fontaine/%3C87sfpop0dm.fsf@contrapunctus.net%3E#%3C87pmksoyv6.fsf@contrapunctus.net%3E

• Simplified the value of the cursory-presets user option. It now looks like this:

    '((bar
       :cursor-type (bar . 2)
       :cursor-in-non-selected-windows hollow
       :blink-cursor-blinks 10
       :blink-cursor-interval 0.5
       :blink-cursor-delay 0.2)
      (box
       :cursor-type box
       :cursor-in-non-selected-windows hollow
       :blink-cursor-blinks 10
       :blink-cursor-interval 0.5
       :blink-cursor-delay 0.2)
      (underscore
       :cursor-type (hbar . 3)
       :cursor-in-non-selected-windows hollow
       :blink-cursor-blinks 50
       :blink-cursor-interval 0.2
       :blink-cursor-delay 0.2))
  

  Thanks to Philip Kaludercic for the patch.

• Fixed the :type of the cursory-presets declaration. The Custom UI should now be able to read all values properly. Courtesy of Philip Kaludercic.
• Named the mailing list address as the Maintainer: of Cursory. Together with the other package headers, it helps the user find our primary sources. This is to conform with work being done in package.el by Philip Kaludercic. I was informed about it here: https://lists.sr.ht/~protesilaos/general-issues/%3C875ykl84yi.fsf%40posteo.net%3E.
• Included a reference to the "devel" version of GNU ELPA. My blog post covers the technicalities: https://protesilaos.com/codelog/2022-05-13-emacs-elpa-devel/.

• Mentioned in the manual the electric-cursor package. The text reads thus:

  The electric-cursor package by Case Duckworth lets the user automatically change the cursor style when a certain mode is activated. For example, the box is the default and switches to a bar when overwrite-mode is on: https://github.com/duckwork/electric-cursor.

Version 0.1.0 on 2022-04-15

Initial release of the package. Please read the manual.

The core idea for this package was implemented in the prot-cursor.el file that is part of my dotfiles (now deprecated). I was using it at least since the end of 2020 or beginning of 2021.
