This package by Adam Porter, aka “alphapapa” or “github-alphapapa”, implements an alternative to the typical coloration of code. Instead of highlighting the syntactic constructs, it applies color to different levels of depth in the code structure.
As prism.el offers a broad range of customizations, we cannot style it directly at the theme level: that would run contrary to the spirit of the package. Instead, we may offer preset color schemes. Those should offer a starting point for users to adapt to their needs.
In the following code snippets, we employ the modus-themes-with-colors
macro: Face specs at scale using the themes’ palette.
These are the minimum recommended settings with 16 colors:
(setq prism-num-faces 16)
(prism-set-colors
:desaturations '(0) ; do not change---may lower the contrast ratio
:lightens '(0) ; same
:colors (modus-themes-with-colors
(list fg-main
magenta
cyan-alt-other
magenta-alt-other
blue
magenta-alt
cyan-alt
red-alt-other
green
fg-main
cyan
yellow
blue-alt
red-alt
green-alt-other
fg-special-warm)))
With 8 colors:
(setq prism-num-faces 8)
(prism-set-colors
:desaturations '(0) ; do not change---may lower the contrast ratio
:lightens '(0) ; same
:colors (modus-themes-with-colors
(list blue
magenta
magenta-alt-other
cyan-alt-other
fg-main
blue-alt
red-alt-other
cyan)))
And this is with 4 colors, which produces results that are the closest to the themes’ default aesthetic:
(setq prism-num-faces 4)
(prism-set-colors
:desaturations '(0) ; do not change---may lower the contrast ratio
:lightens '(0) ; same
:colors (modus-themes-with-colors
(list blue
magenta
magenta-alt-other
green-alt)))
If you need to apply desaturation and lightening, you can use what the prism.el documentation recommends, like this (adapting to the examples with the 4, 8, 16 colors):
(prism-set-colors
:desaturations (cl-loop for i from 0 below 16 collect (* i 2.5))
:lightens (cl-loop for i from 0 below 16 collect (* i 2.5))
:colors (modus-themes-with-colors
(list fg-main
cyan-alt-other
magenta-alt-other
magenta)))
