Configuration

Changing theme

Although this module uses the doom-one theme by default, doom-themes offers a number of alternatives:

doom-one: doom-themes' flagship theme, inspired by Atom's One Dark themes
doom-vibrant: a more vibrant version of doom-one
doom-molokai: based on Textmate's monokai
doom-nova: adapted from Nova
doom-one-light: light version of doom-one
doom-peacock: based on Peacock from daylerees' themes
doom-tomorrow-night: by Chris Kempson

This can be changed by changing the doom-theme variable, e.g.

(setq doom-theme 'doom-molokai)

Changing fonts

core/core-ui.el has four relevant variables:

doom-font: the default font to use in Doom Emacs.
doom-big-font: the font to use when doom-big-font-mode is enabled.
doom-variable-font: the font to use when variable-pitch-mode is active (or where the variable-pitch face is used).
doom-unicode-font: the font used to display unicode symbols. This is ignored if the :ui unicode module is enabled.

(setq doom-font (font-spec :family "Fira Mono" :size 12)
      doom-variable-pitch-font (font-spec :family "Fira Sans")
      doom-unicode-font (font-spec :family "DejaVu Sans Mono")
      doom-big-font (font-spec :family "Fira Mono" :size 19))

Troubleshooting

Strange font symbols

If you're seeing strange unicode symbols, this is likely because you don't have all-the-icons's font icon installed. You can install them with M-x all-the-icons-install-fonts.
