Change Log of the Ef Themes

This document contains the release notes for each tagged commit on the project's main git repository: https://git.sr.ht/~protesilaos/ef-themes.

The newest release is at the top. For further details, please consult the manual: https://protesilaos.com/emacs/ef-themes.

Version 0.6.0 on 2022-09-23

New tri-chrome themes

The collection now includes two themes which apply shades of magenta, blue, and teal in most contexts. They are named ef-trio-dark and ef-trio-light. I think some of you will like their aesthetics.

The announcement includes screenshots (and it also links to the page with all the pictures of the themes): https://protesilaos.com/codelog/2022-09-16-ef-themes-trio/.

As part of the development, I initially forgot to register the "trio" themes as part of the collection. Thanks to Sven Seebeck for informing me about it. (This is shared with permission, as it was done via a private channel.)

Changes to faces or face groups

• Removed the override for the org-modern-label face. We used to affect its properties, which had the unintended effect of breaking the functionality of the user option org-modern-label-border. Users of the org-modern package may thus notice a difference in the effective typography that org-modern-mode produces.

  For the alignment of tables with timestamps (e.g. clocktables), it is recommended to set the user option org-modern-timestamp to nil. The manual covers this information in the section titled "Tweak org-modern timestamps".

  Users who still need help with this are welcome to contact me in private or via the development channels of the Ef themes (mailing list or GitHub/GitLab mirrors).

  Thanks to Daniel Mendler (the org-modern developer) for explaining the technicalities and correcting errors I made in the previous version of that entry in the manual: https://github.com/protesilaos/ef-themes/commit/79bb1436f2fd8ab07e850c247c5616490f619f52.

• Refined the backgrounds of regexp groupings. Commands such as re-builder and isearch-forward-regexp apply distinct colours to matching regexp groups. Those are now optimised to stand out more when seen side-by-side.

  Part of this work involved a thorough review of the applicable hues used by the ef-deuteranopia-dark and ef-deuteranopia-light (the two themes which are designed for users with red-green colour deficiency). The announcement on my website shows screenshots, including those which simulate deuteranopia: https://protesilaos.com/codelog/2022-09-18-ef-themes-deuteranopia-regexp/.

• Added support for display-fill-column-indicator-mode. Thanks to Daniel Mendler for informing me about it (this is shared with permission, as it was done via a private channel).
• Covered two faces that are available on Emacs 29 (current development target) for Version Control: vc-git-log-edit-summary-max-warning, and vc-git-log-edit-summary-target-warning.

Making use of ef-themes-select in init files

The manual includes improved language on how to use the function ef-themes-select in user init files. This is for users who need to leverage the ef-themes-post-load-hook at startup (using that hook is also explained in the manual). Basically, one loads a theme in their init file with something like:

;; like `load-theme' but also call `ef-themes-post-load-hook'
(ef-themes-select 'ef-summer)

Miscellaneous refinements

• Simplified how the variable ef-themes-collection gets its value. Thanks to Philip Kaludercic for suggesting the use of seq-union over at the emacs-devel mailing list: https://lists.gnu.org/archive/html/emacs-devel/2022-09/msg01053.html.

  I could not use seq-union because it introduces a dependency on Emacs 28, whereas we support Emacs 27. I went with append instead.

• Ensured that the background colour of matching delimiters in show-paren-mode is no longer red-tinted. We thus avoid the potential problem of mistaking those highlights for errors of some sort. This affects the themes ef-autumn, ~ef-light, and ef-night.
• Recorded the colour distance and colour contrast between the base background values across all themes. The data is incorporated in the file contrast-ratios.org, which is part of the Git repository and is basically intended for my own use as part of this project's development (though you are welcome to consult it).

What you do not see but still need to know about

I worked on two major changes but refrained from implementing them in this version. Whether I will do so in the future remains to be determined. The first is an option to apply "intense" colouration to the region face. The second pertains to a review of the base backgrounds across all dark themes in order to improve their contrast relative to the main background.

The following sections delve into the specifics. To cut the long story short: changing colours is not trivial work.

Considerations for the "intense" region

The following patch is deceptively simple. It defines some new colour values, adds a tiny function, and a user option. Why not add this to the themes, then? The reason is that colours are never that simple. Any new value for the region must (i) work with hl-line-mode, (ii) respect the highlights of show-paren-mode, (iii) complement or otherwise not interfere with isearch and its lazy highlights or any other search utility that can extend the active region highlight, (iv) keep the cursor visible, and (v) remain thematically consistent with the rest of the theme. Running those checks for 14 themes is no mean feat and there is always the chance that the new colours will still have a negative effect in places that are not expected. Furthermore, there is no guarantee that the number of Ef themes will stay at 14 (I have some more ideas, yes).

It is for such reasons that one of the principles of this project is to NOT offer customisation options that influence colours. They do not scale and will make things unmaintainable.

Revising the dark backgrounds

As with the "intense" region, any change to the base backgrounds has far-reaching implications. The following patch is, again, a matter of making small tweaks to colours values whose effect is far greater than what meets the eye. I mean, what can possibly go wrong by changing the colour #1a1a1a to #232323, right? This marginal adjustment requires, among others, that we also adjust (i) the foregrounds in header lines, (ii) the background colours of added and removed lines in Magit focused diff hunks as well as the backgrounds of word-wise, aka "refined", diff highlights, (iii) the foregrounds of inactive mode lines, (iv) the legibility of inactive tabs in tab-bar-mode, tab-line-mode, (v) the legibility of elements such as the #+begin_src line in Org buffers, and probably many others. A change to one background necessarily needs a change to all others.

This topic is discussed with Alan Schmitt who has one monitor that does not reproduce black properly: https://lists.sr.ht/~protesilaos/ef-themes/%3C87leqe2tji.fsf%40m4x.org%3E.

My suggestion is to calibrate hardware, if possible, such as by relying on those resources:

1. http://www.lagom.nl/lcd-test/black.php
2. http://www.lagom.nl/lcd-test/white.php

[ Yes, I once did spend 8 hours calibrating my monitor. It was crazy. ]

2.37.3

Version 0.5.0 on 2022-09-11

New duo-chrome themes

The collection now includes two items which apply shades of blue and yellow in most interfaces. The themes are named ef-duo-dark and ef-duo-light.

Read the announcement: https://protesilaos.com/codelog/2022-09-06-ef-themes-duo/.

View all image samples: https://protesilaos.com/emacs/ef-themes-pictures.

The choice of blue and yellow is largely stylistic: it is not done to accommodate users with red-green colour deficiency. For that case, the Ef themes provide ef-deuteranopia-dark and ef-deuteranopia-light.

Bespoke accent colours for the mode line

Each theme now includes a subset of foreground values optimised for use against the active mode line's background. The active mode line's background is accented, meaning that we cannot use colours that are otherwise decent against the main background.

These new entries are meant to style warnings, errors, and other notifications that appear on the mode line. They empower us to extend support for packages that make use of such colour-coding (more further below).

"Subtle" accented backgrounds

Each theme's palette now contains six accented backgrounds that are not very intense. These are used by packages that need to (i) highlight a line or region, (ii) preserve a modicum of legibility without overriding existing foreground values (more below about new packages).

Refined the colour of prompts, where necessary

Each theme's palette now includes a dedicated prompt mapping. This gives us full control over what colour we use for prompts. In some themes the prompt will look the same as before, though I made a few changes to have stylistic consistency in each theme. Specifically:

Theme	Old prompt	New prompt
ef-deuteranopia-dark	cyan-warmer	yellow
ef-deuteranopia-light	cyan	blue
ef-duo-dark	green-cooler	yellow
ef-duo-light	green-cooler	blue
ef-spring	blue	green
ef-summer	cyan-cooler	magenta-warmer
ef-winter	green-cooler	magenta-warmer

In short: we don't want prompts to look blue/green all the time. Some themes have a different character.

Newly supported packages

In general, if a package does not look right, it is not supported by the Ef themes. What we have for this release:

auctex

Thanks to Philip Kaludercic for providing the sample file that let me view the relevant faces, as well as for helping me correct some mistakes of mine: https://lists.sr.ht/~protesilaos/ef-themes/%3C87h71t97hl.fsf%40posteo.net%3E.

company

Thanks to Alan Schmitt for reminding me about it: https://lists.sr.ht/~protesilaos/ef-themes/%3C87pmgjw3j9.fsf%40m4x.org%3E.

dirvish

Thanks to Alex Lu (dirvish developer) for the contribution. This was done in pull request 14 at the GitHub mirror: https://github.com/protesilaos/ef-themes/pull/14. The change is below the ~15 line threshold and thus does not require copyright assignment to the Free Software Foundation.

doom-modeline

Expanded support for almost all the faces it provides. The only exception is some debugging-related indicators that I do not know how to trigger (contact me, if you encounter them). This support is made possible by the new accented foregrounds that are designed specifically for the mode line.

gnus

Expanded support for all the faces it defines. I had used Gnus for several months before and am familiar with its interfaces. Though I never made use of its scoring system. I think the relevant faces look okay, though please let me know if we can refine them further.

image-dired

This is made possible by the new "subtle" coloured backgrounds that I added to each theme.

lin (my package)

Made possible by the new subtle backgrounds.

pulsar (my package)

Same as above.

pulse

Same.

recursion-indicator

Same

selectrum

Made it look like the already supported vertico.

tempel

Same as lin and friends.

Refinements to existing faces

• Lots of small tweaks affect mode line indicators, per the new foreground colours I introduced. Expect to see a bit more colour in the mode line when using magit, compilation buffers, appointment reminders, keyboard macros, Org agenda filters, and more.

• All the rcirc faces have been revised in the interest of thematic consistency.

  • Rcirc uses the new foregrounds for the mode line, where relevant.
  • Indicators that track/highlight the user's nick use the same paradigm.
  • IRC server messages look like comments in code buffers.

  Thanks to Philip Kaludercic for telling me about the downsides of using the italic in the rcirc-nick-in-message-full-line face: https://lists.sr.ht/~protesilaos/ef-themes/%3C87edwphahl.fsf%40posteo.net%3E.

  Please note that I am not a regular/experienced IRC user. If there are improvements to be made, I am happy to implement them but will likely need your help (I will ask the relevant questions).

New fallback behaviour for ef-themes-toggle

The command ef-themes-toggle will switch between two themes specified in the user option ef-themes-to-toggle. For example:

;; Toggle between `ef-summer' and `ef-winter' using `ef-themes-toggle'.
(setq ef-themes-to-toggle '(ef-summer ef-winter))

By default, ef-themes-to-toggle is nil. In the past, this meant that ef-themes-toggle would do nothing out-of-the-box. To improve the initial user experience, the command will now fall back to minibuffer completion to load a theme if ef-themes-to-toggle does not have the expected value. The completion candidates are the items of the Ef themes collection. This fallback behaviour is essentially the same as what the user gets by invoking the ef-themes-select command.

When ef-themes-to-toggle is set properly, the corresponding command will perform the switch, as intended.

This is based on the discussion with Philip Kaludercic about revising the ef-themes-toggle command to have a more Do-What-I-Mean behaviour: https://lists.sr.ht/~protesilaos/ef-themes/%3C878rmwfs0e.fsf%40posteo.net%3E.

Improved how ef-themes-load-random picks subsets

The ef-themes-load-random command accepts a prefix argument (C-u, by default): it prompts the user for a dark or light subset out of the collection. Once that is selected, the command loads a theme at random.

Before, the prompt was using minibuffer completion, but this has now changed to a read-multiple-choice function, meaning that d selects dark and l selects light. Basically, we skip possible extra key presses.

Thanks to Philip Kaludercic for the patch: https://lists.sr.ht/~protesilaos/ef-themes/patches/35089.

Internal changes

• Fixed the initial colors' list in the ef-themes-with-colors macro. Thanks to Steve Molitor for telling me that the previous design would not work if ef-light was not loaded. This was done in issue 11 at the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/11.
• Simplified the helper function ef-themes--current-theme. Thanks to Jonas Collberg for the feedback in issue 12 over at the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/12. Also thanks to Jonas for the subsequent patch in pull request 13: https://github.com/protesilaos/ef-themes/pull/13. The change is below the ~15 line threshold and thus does not require copyright assignment to the Free Software Foundation.

• Refined the colour mapping of some themes to improve overall aesthetics and/or usability, without deviating from the theme's established character. For example, in the ef-dark I adjusted the mappings for dates, links, and names. This helps distinguish all elements, while retaining the overall looks of the design. Some contexts where that is relevant:

  • Notmuch search buffers
  • Magit commit log
  • Org clocktables
  • Org documents with links, to-do, etc.

  I will not cover all such technicalities. Please consult the Git commit log. If, however, some new combination of colours feels awkward, you are welcome to tell me about it.

• Made improvements to the manual and implemented other internal changes.

Version 0.4.0 on 2022-08-29

New deuteranopia-friendly themes

Designed two bespoke themes for users with red-green colour deficiency or blindness (deuteranopia). They rely on blue and yellow hues. Their names are:

• ef-deuteranopia-dark
• ef-deuteranopia-light

Announcement with sample pictures: https://protesilaos.com/codelog/2022-08-19-ef-themes-deuteranopia/.

User options

• Introduced the variable ef-themes-mixed-fonts. When it is set to a non-nil (t) value, it makes spacing-sensitive elements use a monospaced font. For example, Org tables and code blocks will always look properly aligned. This is useful for those who either use a proportionately spaced font as their default or enable the built-in variable-pitch-mode.
• Implemented the variable ef-themes-variable-pitch-ui. When it is set to a non-nil (t) value, it renders the mode-line, tab-bar-mode, and tab-line-mode in a proportionately spaced font.

User options must be set before the theme is loaded. If an option changes, its value will be read upon a theme re-load.

For font configurations, refer to my fontaine package.

Newly supported packages

Built into Emacs:

• eww
• shell-script-mode (sh-mode)
• shr

External packages:

• consult
• embark

Refinements to faces

• Fixed the scaling of current line of display-line-numbers-mode when text-scale-adjust was invoked. Basically I forgot to include the line-number face, while all others were covered. Thanks to Anthony Chavez for the feedback in issue 7 over at the GitHub mirror: https://github.com/protesilaos/denote/issues/7.
• Covered all faces that define group titles in completion contexts. These are headings which are used by various commands, such as consult-buffer, consult-imenu, and consult-grep. As they denote a group name, we apply the name colour mapping (the hue differs for each theme). And since they are titles, we inherit from bold to make them look like headings. Thanks to Summer Emacs for the feedback which amounted to:
  1. Treating group titles as headings.
  2. Using a more consistent colour theme-wide.
• Revised the compilation-info face from a colour-coded "success" face to a value that is consistent with the semantics of its application in file names or related (as seen in the emacs.git repository). For example, file names in Grep or Xref buffers will now look like they belong to the theme, whereas before they were predominantly green, even when that did not make sense. This point is connected to the above, such as in workflows that go from the minibuffer to a Grep buffer (e.g. with the use of the embark package).
• Toned down the vertical border between windows by explicitly supporting the vertical-border face. The previous design would use the main foreground which generally led to a disproportionately intense result.

• Adjusted all spacing-sensitive faces to accommodate the user option ef-themes-mixed-fonts, as noted above. Also thanks to Christopher League for spotting that I had missed the line-number face and for providing the relevant patch (I do the same in the modus-themes): https://lists.sr.ht/~protesilaos/ef-themes/%3C871qt2x4wi.fsf%40nita.mail-host-address-is-not-set%3E

  The patch is well below the ~15 line threshold and thus does not require copyright assignment to the Free Software Foundation.

• Enforced mono spacing for the org-indent face. This is essential for org-indent-mode to align entries correctly. Thanks to Steve Molitor for reporting this in the issue 9 over at the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/9. Steve tested a sample file with modus-vivendi and got the desired results. It reminded me how I handle this face in the modus-themes.
• Added explicit support for the bold and italic faces. The default definition of italic has conditionality which we do not want, such as drawing an underline if the font does not have italics (e.g. Fira Code). Styling it at the theme level prevents that from happening: the font without italics will simply use the upright/roman glyphs. Adding bold is just for clarity. Its default definition is fine.
• Made the tabs of the built-in tab-bar-mode and tab-line-mode stand out more. The difference between the current tab and the rest was too subtle. Depending on the lighting conditions, their respective backgrounds were indistinguishable. Thanks to Summer Emacs for reporting this issue and for helping me decide on the final design.
• Applied tinted backgrounds to values and arguments in transient.el buffers (e.g. Magit). They now stand out better.

Documentation

• Created a page with screenshots of all the Ef themes: https://protesilaos.com/emacs/ef-themes-pictures.

• Answered the Frequently Asked Question of letting Org tags inherit the foreground colour of the heading they belong to. The gist (though note that the entry also mentions the option for the non-alignment of tags):

  Upstream Org defines tags in headings to have the same color as the rest of the heading's text. However, tags are a distinct component of the heading as noted in the doc string of the org-get-heading function. Tags also are functionally different than the ordinary text of the heading: they are a clickable link/button. It thus is a matter of usability to render this distinction clear at the visual level: I do not agree with upstream Org's design decision.

• Addressed another Frequently Asked Question on whether we can have Ef-style themes inspired by the Nord or Zenburn themes. The short version is that this is technically difficult and undesirable. Each palette in the Ef themes collection is original and is designed around the normative and aesthetic principles of this project.
• Wrote an entire section on Do-It-Yourself customisations. These generally are for advanced users, though the manual provides concrete examples of using the ef-themes-with-colors macro in tandem with the ef-themes-post-load-hook.

• Elaborated on the list of packages that I will most likely NOT support in the Ef themes. The reasons vary though. Quote:

  These are difficult to support due to their (i) incompatibility with the design of the ef-themes, (ii) complexity or multiple points of entry, (iii) external dependencies, (iv) existence of better alternatives in my opinion, or (v) inconsiderate use of color out-of-the-box and implicit unwillingness to be good Emacs citizens

  If a certain package does not look right, then it is not supported (yet).

The manual can be read from Emacs, if the ef-themes package is installed. Evaluate:

Internal refinements

• Recalibrated diff colours or the context of diff buffers, especially in Magit, to improve usability.
• Adjusted or otherwise tweaked the hues that apply to key bindings and links in order to reinforce the stylistic consistency of each theme.
• Introduced a yellow-tinted background which is used in various contexts that (i) should be styled with a coloured background but (ii) should not be colour-coded as either red or green/blue.
• Made the ef-themes-with-colors macro always reify the current Ef theme's palette. This macro is for advanced users. Its utility is documented in the themes' manual.
• Fixed how themes become "known" at startup. Before, they were not registered correctly for immediate use with the ef-themes-select command. Thanks to Jean-Philippe Gagné Guay for the feedback in issue 6 over at the GitHub mirror: https://github.com/protesilaos/denote/issues/6.
• Tweaked some face attributes to work with Emacs 27.
• Tinkered with the colour mapping or precise values of practically all the themes. Better consult the Git log for the minutiae. I think the identity of each theme is largely defined, though there may still be tweaks to be done here and there until we eventually reach version 1.0.0.

Version 0.3.0 on 2022-08-20

User-facing changes

• Revised the minimum Emacs version of the ef-themes package. It now depends on Emacs 27.1 instead of Emacs 28.1. Relevant internal adjustments were made, some of which are courtesy of Philip Kaludercic: https://lists.sr.ht/~protesilaos/ef-themes/patches/34787.

  [ Philip has assigned copyright to the Free Software Foundation. This is necessary for all non-trivial patches. ]

• Added two new themes to the collection which are designed for users with red-green colour deficiency/blindness (deuteranopia). In simple terms, their effective palette consists of blue, yellow, and the base tones. The themes are named descriptively: ef-deuteranopia-dark and ef-deuteranopia-light. Announcement with screenshots: https://protesilaos.com/codelog/2022-08-19-ef-themes-deuteranopia/.
• Reconsidered the principle of what kind of user options are acceptable. Those which affect colours directly will never be a part of the project. Others are subject to consideration with a preference for simplicity. Detailed documentation to do-it-yourself will still be preferred over user options.

• Implemented the ef-themes-headings user option which provides the mechanism to change the weight and height of each heading level, as well as set it to variable-pitch (i.e. a proportionately spaced font). The doc string of that variable or the relevant entry in the manual explain the particularities and provided code samples.

  To accommodate this variable, the default style of all headings has been revised to remove the added height they once had. Users who preferred the previous style must add the following to their configuration BEFORE the code that actually loads the theme (e.g. a load-theme call):

    ;; Restore height of each heading level to its previous value.
    (setq ef-themes-headings
          '((0 . (1.9))
            (1 . (1.8))
            (2 . (1.7))
            (3 . (1.6))
            (4 . (1.5))
            (5 . (1.4))
            (6 . (1.3))
            (7 . (1.2))
            (t . (1.1))))
  
    ;; First set the above configuration, then load the theme (changes to
    ;; user options require a theme re-load).
    (load-theme 'ef-summer :no-confirm)
  

• Introduced the command ef-themes-toggle and the companion user option ef-themes-to-toggle. To use the command, one must first set their two preferred Ef themes, such as with this:

    (setq ef-themes-to-toggle '(ef-summer ef-winter))
  

  The names of all the themes are included in the ef-themes-collection variable. Though recall that the commands ef-themes-select and ef-themes-load-random still use the entire collection (read their doc strings or consult the manual).

• Fixed how themes are made available at startup. Before, there was a mistake to how items were registered as "known" and were thus not recognised by our commands, even though the standard load-theme worked as expected. Thanks to Iris Garcia for reporting the problem in issue 2 on the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/2. It was propagated to users as version 0.2.1 of the ef-themes.

• Added support for these packages:

  • chart
  • doom-modeline (tentative)
  • info
  • org-habit
  • rcirc
  • smerge

  Thanks to Spike-Leung for reminding me about org-habit in issue 5 over at the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/5.

  [ Remember that if a package looks awfully out of place, it is not support (yet). ]

• Expanded and/or clarified the manual, including an answer to the question of what "Ef" means:

  "Ef" is a Greek word (ευ), commonly used as a prefix to denote that something is good, nice, and/or easy. For example, eftopia (ευτοπία) is the opposite of dystopia (δυστοπία): a good place as opposed to a bad place.

• Helped Adam Sherwood figure out why zsh-autosuggestions did not look right. In short: this has nothing to do with Emacs. Try to avoid termcolor{0,7,8,15} as a default. Prefer the remaining nominal accent colours, as every theme is more likely to work with those, whereas, say, termcolor0 ("black") will not be legible with dark themes. This was done in issue 3 on the GitHub mirror: https://github.com/protesilaos/ef-themes/issues/3.

Internal refinements

• Recalibrated lots of colour values and mappings across several themes. The changes are small and help with the internal consistency of each theme. Consult the Git commit log for the minutiae.
• The internal faces for headings are now done with a dotimes call on custom-declare-face instead of a bespoke macro. Thanks to Philip Kaludercic for the patch: https://lists.sr.ht/~protesilaos/ef-themes/patches/34791.
• Applied file-equal-p for the registration of the themes in the relevant path. Doing so is generally more resilient than equal and might avoid an unexpected edge case in the future. Thanks to Philip Kaludercic for the patch: https://lists.sr.ht/~protesilaos/ef-themes/patches/34789.
• Opted for {if,when}-let* over {if,when}-let. The former do not support the obsolete single-binding syntax, and make clear that both macros operate more like let* than let by evaluating and binding variables sequentially. Thanks to Philip Kaludercic for the patch: https://lists.sr.ht/~protesilaos/ef-themes/patches/34787.

Acknowledgement for the first version of the project

Thanks to user Summer Emacs whose feedback helped define the identity of the ef-summer theme. Summer's comments pertained to the need to increase the occurence of yellow as the theme used to be predominantly magenta and purple. I thus implemented the revised colour mapping and made the relevant adjustments. Without Summer's comments, ef-summer wouldn't have been as pretty.

No release notes were produced at the time. This version included various stylistic refinements and added commands for (i) loading a theme and (ii) previewing a theme's colour palette.

The commands which load a theme call the ef-themes-post-load-hook. Advanced and/or do-it-yourself users may have a use for it. The manual will eventually provide specific code samples.

There were no release notes for it. It established the foundations of the project: the main macros, the character of each theme, etc. Check the Git commit log for more.
