circadian.el's Introduction

Hey 👋

I'm a programmer & creative technologist from Germany.

In 2016 I got my masters degree at the University of Koblenz in Computational Visualistics, a computer science program with a special focus on computer graphics and image processing mixed with courses from interdisciplinary fields such as art history, drawing and media art.

Currently pushing bits and pixels @ FIELD

My interest lies in connecting technology with creative disciplines. I love to build generative visuals and interactive visual systems. I am a member of a hobbyists light artist collective Pendeloque, which mainly performs in the area of Mannheim and Heidelberg.

hibernate system on weekend use wrong theme after system up

My sunrise time is 6:11, sunset time is 18:25, the system is hibernated at
2018-09-15 21:44:23, and up at 2018-09-17 10:10:23.

In *Messages* we can see it switch themes one by one, and finally use the
wrong theme tao-yin. When i reevaluate my circadian configurations the right
theme tao-yang is used.

My circadian emacs configuration:

;; circadian
(use-package circadian
  :custom
  (circadian-themes (if t
                        ;;; colorless
                        '((:sunrise . tao-yang)
                          ("14:00" . base16-grayscale-dark)

saving desktop: theme wouldn't switch

I use circadian happily and also desktop-save-mode.
When I shut down emacs in the evening and open it up in the morning, the dark theme is saved (and vice versa with the light theme). Is there a way to reload the correct theme with desktop-save-mode?
Thanks.

config:

(desktop-save-mode` 1)
(setq desktop-restore-frame nil)

;; ALSO: saving the window configuration; maybe that's the issue here

  "window configuration to use")
(defvar new-ediff-frame-to-use nil
  "new frame for ediff to use")
(defun save-my-window-configuration ()

  (setq pre-ediff-window-configuration (current-window-configuration))

how it overrides previous theme?

Hi,

Before, when I switch off the last theme I get emacs default theme selected. It is not longer true with this package - instead of showing up emacs default theme it shows previous one. As result, next theme colors get inherited from previous one (and not from default), making themes look different and unusable. So, basically the effect is the same as if you check "select more then one theme at a time" checkbox - instead of switching theme fully, it will combine previous and next one.

Expected behavior: when theme deselected, emacs default theme appears.

WBR,
Alex

Provide list of themes for sunset/sunrise/timeslot

Allow setting a list of themes, that should get loaded on a timeslot (or sunset/sunrise). When loading a theme, it should randomly get selected from that list

Improve code

Three minor things:

Use -*- lexical-binding: t; -*-.
The functions first, fourth, third, second, and remove-if all belong to the deprecated cl package. You should add a cl- prefix to each and require cl-lib. Currently your package will only work if the user had already loaded cl for some reason.
Change mapcar to mapc in circadian-setup.

The last two issues are caught trivially with the byte compiler. You can do a spot check like so:

emacs -Q -batch -f batch-byte-compile circadian.el

Thanks to skeeto via reddit for these proposals.

keep current theme if there is no time slot defintion

I would like to suggest to keep current selected theme if the current time don't match time intervals.
E.g. I've tried this:

(use-package circadian
  :load-path "~/.emacs.d/config/circadian/"
  :ensure t
  :config
  (setq circadian-themes '(("11:00" . avk-daylight)
                           ("18:30" . avk-darkblue-yellow)
                           ("22:00" . warm-night)))
  (circadian-setup))

but it fails with this error:

Error (use-package): circadian :config: Invalid theme name ‘nil’

... because it is 07.43 on clock so first time slot is not started

For this case there should be some workaround. I suggest to not switch theme, another idea is to get previous one.

sunrise-sunset returns string not parseble by Circadian in Germany

When running this very snipped (with calendar-latitude/longitude set)

(setq circadian-themes '((:sunrise . whiteboard)
                         (:sunset . tsdh-dark)))
(circadian-setup)

I recieve the following error:

  eval-last-sexp-1(nil)
  eval-last-sexp(nil)
  call-interactively(eval-last-sexp nil nil)
  command-execute(eval-last-sexp)

The problem appears to be that Circadian is expecting some string format from (sunrise-sunset) but the function returns the following for me:
#("Wed, Apr 18, 2018: Sunrise 6:41am (Mitteleuropäische Sommerzeit), sunset 8:38pm (Mitteleuropäische Sommerzeit) at Aachen, DE (13:57 hours daylight)" 35 63 (charset windows-1252) 81 109 (charset windows-1252)).

Sadly, this breaks the whole package for me

Add Emacs sunset/sunrise

Emacs provides functions to determine sunset and sunrise. Should be added as feature

Infinite loop when running `(circadian-activate-current)`

Hello. I am on the latest version of Emacs 30 and running the following code from emacs -Q:

(defvar bootstrap-version)

(let ((bootstrap-file
       (expand-file-name "straight/repos/straight.el/bootstrap.el" user-emacs-directory))
      (bootstrap-version 5))
  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously "https://raw.githubusercontent.com/raxod502/straight.el/develop/install.el"
                                    'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(straight-use-package 'circadian)

(require 'calendar)
(setq calendar-latitude 28
      calendar-longitude -96)

(require 'circadian)

(setq circadian-themes
      '((:sunrise . modus-operandi-tinted)
        (:sunset  . modus-vivendi-tinted)))

(circadian-activate-current)

causes the package to reload the current theme in an infinite loop and consequently this makes the screen flicker a lot.

circadian-themes switch interval problem

(use-package circadian
  :config
  (setq circadian-themes '(

			   ))
  (circadian-setup))

At current time 2020-08-25 13:10:00 . I eval last config then the theme doom-oceanic-next enabled, but when I checked timer-list variable

( [nil 24388 40706 309167 nil undo-auto--boundary-timer nil nil 0]
  [nil 24388 40737 26724 60 ac-clear-variables-every-minute nil nil 0]

;;  '(24389 6496 0)
;; )
;; => "2020-08-25 22:00:00 +0800"  run circadian-activate-latest-theme function

I saw the circadian-activate-latest-theme function next run at 2020-08-25 22:00:00

but it should not be running at 14:00 (for wombat theme) as circadian-themes variable defined

How to override or stop circadian?

I set up and initialized Circadian as suggested, but then decided I wanted for the moment to use a different theme. However, circadian doesn't allow the theme to be reset -- it's not that attempting to set the theme fails exactly, but after load-theme completes, circadian changes it back.

I don't even seem to be able to figure out how to turn off circadian so I can set a different theme, temporarily or permanently. Even uninstalling the package doesn't seem to kill it--or allow me to change themes....

So,

How does one override or pause circadian so you can change to a different theme temporarily?
How does one stop or disable circadian? Once started, does it just run without end until emacs itself is terminated or restarted?

Circadian crashes above arctic circle

Hi! Thanks for the nice package, I'm happily using it.

I have an annoying edge case for you... I current live somewhere north of the arctic circle, and this means that there are currently no sunsets or sunrises. This means that (solar-sunrise-sunset (calendar-current-date)) evaluates to (nil nil "0:00") instead of the usual ((6.8833333337679505 "CET") (16.283333332277834 "CET") "9:24") (for example). This means that circadian--frac-to-time receives a value of nil when circadian is set up, and raises and error.

Could you possibly add a test for this somewhere? Ideally, of course, circadian should just use the "sunset" theme when the sun is currently down (which should be checked for somehow, since solar-sunrise-sunset will return nil regardless) and the "sunrise" theme when the sun is currently up.

Let me know if you would like me to have a stab at fixing this!

Problems with switching themes

I tried leuven and distinguished as themes switched by circadian. Switching from leuven (MELPA version) to distinguished left some settings from leuven in the new theme, i.E. in gnus groups buffer the topic header were not readable because leuven sets bold to bold/black and distinguished leaves it this way

Use `enable-theme` in favor of `load-theme`

It would be a good idea to check, if the designated theme in circadian-enable-theme was loaded before in the current Emacs session and if that's the case, rather use enable-theme than load-theme

[Request] Running a theme-change-hook and persisting theme as variable?

Hi,

Wanted to request getting a theme-change-hook as well as persisting the theme variable on change.

I believe custom-enabled-themes contains a list of enabled themes but it might be more explicit to manage one in this package.

Thanks!

UTC Time Only?

This is mostly just a question. I was playing around with circadian and I love the idea of it! However, right now it is reading only UTC time. I have the time displayed in my emacs and that is the correct local time. But when setting circadian it was always my dark theme when it should have been the light theme. After playing around I realized it is UTC (which I am in UTC -6). So I would have to set the times to +6 hours from my actual time. It shouldn't be an issue, but wondered if there was a way to set the time circadian uses or where it derives its's time from?

circadian-setup is very heavy

When I execute (circadian-setup), Emacs is suspended a few minutes, lot of I/O. (why circadian-setup has heavy I/O?)

So I take a profiling with Emacs profiler:

Timezone/time on Windows seems to be off by one hour

Describe the bug
Using circardian--encode-time on Windows seems to offset the time by 1 hour.

To Reproduce
Steps to reproduce the behavior:

Execute eval-expression and enter (decode-time (circadian--encode-time 11 54))
Result is one hour off, eg (0 54 12 22 4 2024 1 t 7200)

Expected behavior
Using (decode-time (circadian--encode-time 11 54)) should not offset time by one hour.

Environment (please complete the following information):

OS: Windows 11
Emacs: Emacs 29.3

Integration with macOS system theme preference?

I'm looking for a way to synchronise the Emacs theme with light/dark/auto mode on macOS. I understand the current method is completely cross-platform, but it would be great to integrate with specific platforms' capabilities.

Theme not fully loaded on switch

Thanks for this great package! And for the theme suggestions, I love them!

I'm using a very similar setup as the one from the README:

  (setq calendar-latitude 26.084534)
  (setq calendar-longitude -80.238454)
  (setq circadian-themes '((:sunrise . apropospriate-light)
                           (:sunset  . nord)))
  (circadian-setup)

The switch as sunrise/sunset does occur, but leaves me with a theme not fully loaded. Here is a screenshot of a session using Polymode on a RMarkdown file (so essentially mixing Markdown and ESS mode), after a sunset switch to Nord theme:

Simply closing and restarting Emacs shows what I should have:

What's missing is the correct background in the ESS chunk. Not too sure where to starts from here…

Theme change scheduled to wrong day.

I have two entries in circadian themes:

(setq circadian-themes '(("09:00" . 'theme-one) ("18:00". 'theme-two)))

When I launched my Emacs in 08:30, theme-two was applied, but switch to theme-one was planned on 09:00 of the next day.
Just in case I'll put here workaround (until proper bugfix) - just add entry ("00:01" . 'theme-two) to circadian themes.
