## Summary:

  # Ef (εὖ) themes for GNU Emacs

  IMAGES HERE: <https://protesilaos.com/emacs/ef-themes-pictures>.

  The `ef-themes` are a collection of light and dark themes for GNU Emacs
  whose goal is to provide colorful ("pretty") yet legible options for
  users who want something with a bit more flair than the `modus-themes`
  (also designed by me).

Version 1.3.0 on 2023-08-09
═══════════════════════════

Try the aquatic "Maris" variants
────────────────────────────────

  The `ef-maris-dark' and `ef-maris-light' are a pair of themes with a
  grey-blue background, combined with blue, cyan, and green accents.
  Much like the "Elea" variants that were published in version 1.2.0 of
  the `ef-themes', the "Maris" variants are optimal for those times
  where environmental lighting is neither too bright nor too dim.

  There now are 26 themes in the `ef-themes' package, covering a broad
  range of preferences and needs.  They all are highly legible and
  customisable (consult their manual).


Shortdoc has consistent typography
──────────────────────────────────

  The default built-in `shortdoc' face inherit the `variable-pitch'
  face, which renders the text in the buffer proportionately spaced.  To
  me, this feels out of place.  If the user wants Help and related
  ancillary material to be typeset thus, they can enable
  `variable-pitch-mode' (e.g. via a hook).

  Thanks to Bruno Boal for pointing out that the Ef themes did not cover
  Shortdoc.  The message was conveyed via a private channel and the
  information is shared with permission.


Key bindings in minibuffer prompts stand out
────────────────────────────────────────────

  Steve Molinor informed me about a case where a key binding was shown
  as part of the minibuffer prompt.  For some Ef themes, the result was
  suboptimal due to the proximity of the colours involved.  I made all
  the requisite tweaks, such that key bindings in prompts will stand out
  (always in accordance with the principle of avoiding exaggerations).
  Affected themes are:

  • `ef-bio-theme'
  • `ef-deuteranopia-dark-theme'
  • `ef-duo-light-theme'
  • `ef-elea-dark-theme'
  • `ef-elea-light-theme'
  • `ef-frost-theme'
  • `ef-night-theme'

  This was done in issue 24 on the GitHub mirror:
  <https://github.com/protesilaos/ef-themes/issues/24>.


The `ace-window' package is supported
─────────────────────────────────────

  The `ace-window' package now uses colours that are aligned with the
  active Ef theme.  This is mostly a stylistic consideration, except for
  the deuteranopia- and tritanopia- optimised themes, where the hue
  matters greatly.


The Ef commands with completion use a "completion table"
────────────────────────────────────────────────────────

  [ This is for advanced users or developers. ]

  Commands such as `ef-themes-select' and `ef-themes-preview-colors' use
  the minibuffer to pick a theme among the collection.  In the past, the
  set of candidates did not have any metadata associated with it, so
  Emacs could not tell what it was completing against.

  The collection is now annotated with the completion category `theme'.
  Packages that can use this data include `consult', `embark', and
  `marginalia', while the built-in `completion-category-overrides' may
  be involved.  For example, one may define a custom annotation function
  for Marginalia, such that the alignment of the doc strings is at
  column 40 instead of the generic default (I do not add any alignment
  at the theme level to keep it agnostic of the completion front-end).
