;; Doom exposes five (optional) variables for controlling fonts in Doom. Here
;; are the three important ones:
;;
;; + `doom-font'
;; + `doom-variable-pitch-font'
;; + `doom-big-font' -- used for `doom-big-font-mode'; use this for
;;   presentations or streaming.
;;
;; They all accept either a font-spec, font string ("Input Mono-12"), or xlfd
;; font string. You generally only need these two:
(setq doom-font (font-spec :family "monospace" :size 14))

;; There are two ways to load a theme. Both assume the theme is installed and
;; available. You can either set `doom-theme' or manually load a theme with the
;; `load-theme' function. This is the default:
(setq doom-theme 'doom-one)

;; If you use `org' and don't want your org files in the default location below,
;; change `org-directory'. It must be set before org loads!
(setq org-directory "~/org/")

;; they are implemented.

@Raagh yeah that's how I have it now. But you need to make sure you have purs on your $PATH from memory it struggles when it's only install locally to the project (so try installing purescript globally)! also with doom-emacs I make sure to run doom sync to make sure all my paths are up to date.

Thanks for answering. yeah after installing it globally it works fine. I couldn't make it work locally.

cool, glad you got it working 😄
