Emacs: modus-themes version 3.0.0
I will now prepare the patch for emacs.git (currently Emacs 29) which
will then trickle down to GNU ELPA (the
modus-themes is a
package). Thank you for your patience!

The version that will ship with Emacs 29
modus-vivendi themes (package name is
modus-themes) have been a part of Emacs since August 2020. Emacs 28
ships with version 1.6.0 of the themes. Emacs 29 will include version
There is no clean upgrade path from the old version of the themes to the current one. Users are advised to review their configurations and consult with the detailed manual of the themes.
I am available to answer any questions, either via my personal email or on the official sources of the themes. Find the full list here: https://protesilaos.com/emacs.
Minor breaking changes
I have changed the default value of the following user options:
In the case of the first two, the background of the highlighted line is made to look a bit more intense.
For the fringes, this tweak makes them visible, using a subtle grey colour. By default, “fringe” is an 8-pixel-wide area to the left and right side of an Emacs window.
The intent of these changes is to make the out-of-the-box experience consistent with the accessibility considerations of the Modus themes. Specifically because some users may not realise that the themes are highly customisable.
To revert to the old defaults, users must include this (or equivalent) in their init file:
(setq modus-themes-completions nil modus-themes-hl-line nil modus-themes-fringes nil)
As always, changes to theme user options take effect upon a reload of the theme.
This was announced on my website: https://protesilaos.com/codelog/2022-10-23-breaking-modus-themes-3-0-0-notice/.
Support for new faces or changes to existing ones
telegafaces for inline code and preformatted elements. The faces are
telega-entity-type-pre, respectively. This change makes them subject to the style specified in the user option
Thanks to Pablo Stafforini for showing me screenshots of how they look, as I am not a telega/telegram user and cannot do this myself. Done as part of issue 170 on the GitLab mirror: https://gitlab.com/protesilaos/modus-themes/-/issues/170#note_1143975582.
Removed all attributes from the
textsec-suspiciousface. By default, it applies a background, but does not affect the foreground. The result is thus inaccessible in many cases (e.g. blue links against a red background). There is no need for such a background though, as the warnings are accompanied by the relevant emoji: ⚠️.
To support this face, we need it to affect the foreground as well.
consult“preview” faces in the interest of consistency. This is to match the current style of the project: https://github.com/minad/consult/commit/1343e39fefcf8a28a7a415aa4b0a8ff7094370bf.
Expanded support of the built-in
diff-modefaces to include the
diff-changed-unspecified. It is made to look the same as
diff-changed, i.e. yellow-tinted. There is a good chance that a user will never see this face in action (I only encountered it once).
Reworked all the
hi-yellow) to use bespoke colour values.
These faces need to have a background that is consistent with their semantics. Furthermore, they need to use the
inverse-videoattribute which, in turn, affects the combinations of colour we can apply. Our accented backgrounds are designed to contrast well with our nominal main foreground values, whereas this case demands coloured backgrounds that contrast nicely with what would normally be the main background colour. As such, we cannot apply our ordinary entries from each theme’s palette. It would be inefficient to expand the palette of each theme just for this edge case.
Thanks to Kevin Kainan Li for the feedback on the mailing list, where they informed me that the previous design was too dark/mute (and I agreed with that assessment) and provided feedback on my samples: https://lists.sr.ht/~protesilaos/modus-themes/%3CCAMTq2Vp3Nnzv-i9wJdq4-OJ4X_QfWXySpUtAieBy0dgKLEOSBg%40mail.gmail.com%3E.
modus-themes-completion-match-1to use a shade of blue instead of cyan. This contributes to the distinctiveness of those matches relative to
modus-themes-completion-match-0and the other groups. These faces are used in completion User Interfaces, such as
orderless. They are subject to the user option
Added support for the
olivetti-fringeface. Its background is the same as the main background, meaning that the fringes are invisible when
olivetti-modeis enabled. Thanks to Matthias Fuchs for producing a report that helped me track this problem. It was done in issue 46 on the GitHub mirror: https://github.com/protesilaos/modus-themes/issues/46.
Added the new Emacs 29 theme properties to
modus-vivendi. These make the themes work with the new built-in command
toggle-theme. Thanks to Philip Kaludercic for the patch and for the work on this in emacs.git: https://lists.gnu.org/archive/html/bug-gnu-emacs/2022-10/msg00886.html.
Refrained from deprecating the
modus-themes-togglecommand in favour of the new generic
toggle-themeis not functionally equivalent to the command
modus-themes-toggledue to the optional arguments it accepts. With
toggle-themewe are prompted to confirm loading the theme, due to how unsafe themes can be… Further, we are asked to add the loaded theme to the list of “safe” themes. This only applies to the packaged version of the
modus-themes, not the items that are built into Emacs.
These prompts are consistent with how
load-themeworks, but not with what the user of
modus-themes-togglehas come to expect.
Users who do not like to maintain a
custom-file(like me) are thus penalised each time they invoke the command.
modus-themes-togglewill only be deprecated if there is, say, a user option in Emacs that disables those prompts each time a theme is loaded. Basically, we need an arrangement that just toggles themes without questions.
Thanks to Rudolf Adamkovič for suggesting the idea and to Philip Kaludercic for the
toggle-theme(and related functionality): https://lists.sr.ht/~protesilaos/modus-themes/%3C877d116lh4.fsf%40posteo.net%3E#%3Cm2lepgrd8l.email@example.com%3E.
Corrected the one-line description of the
modus-vivenditheme, which was describing itself as a “light” theme.
Ensured that the manual and all doc strings in the code uses American English, per the convention of emacs.git (my CHANGELOG still uses what I prefer). Thanks to Stefan Kangas for contributing to this effort with a patch that properly renders
non-nilin the texinfo output as
Made other minor tweaks and refinements.
