Modus themes

The Modus themes from Emacs: Modus Vivendi, white on black, and Modus Operandi, black on white. They're made for the highest color contrast (WCAG AAA), so text is easy to read in either.

Turning them on

The Modus themes are an opt-in package. Load it in init.scm, then load a theme:

(use-package! 'modus-themes)
(load-theme! 'modus-vivendi)

Once the package is loaded, modus-vivendi and modus-operandi work like imp's other themes: switch with :theme modus-operandi, or press SPC t T and pick one. See Look.

The colors are Modus's own, for code, the status line, popups, diagnostics, diffs and git, Org, dired and terminals. Docstrings and builtins, such as built-in functions and types, get their own colors.

Switching between them

M-x modus-themes-toggle switches between Modus Operandi and Modus Vivendi. From any other theme, it loads Modus Operandi.

It has no key of its own. To put it on one:

(define-leader! "tm" 'modus-themes-toggle "modus toggle")

Bold and italic

Both are off, as in Emacs. Turn them on in init.scm:

(set-option! 'modus-themes-bold-constructs #t)   ; keywords, builtins, types, labels, modules
(set-option! 'modus-themes-italic-constructs #t) ; comments and docstrings

Changing the colors

Modus names every color it uses, and names what each color is for, such as keyword or bg-main. Give a name a new value and everything using it follows. The value is a color, or another name:

(set-option! 'modus-themes-common-palette-overrides
             '((keyword red) (bg-main "#111111")))

That makes keywords red and the background near-black, in both themes. To change only one theme, use modus-vivendi-palette-overrides or modus-operandi-palette-overrides; those win over the common list. A name Modus doesn't have is an error that names it.

Changing any of these options redraws a Modus theme that's loaded.
