;; This file add conda support to doom-emacs. To get started, try `M-x'
;; `+python/set-conda-home' and then `M-x' `conda-env-activate'.
;; Adds conda support to Doom Emacs. `conda-anaconda-home' should be the path to
;; your anaconda installation, and will be guessed from the following:
;;
;; + ~/.anaconda3
;; + ~/.anaconda
;; + ~/usr/bin/anaconda3
;;
;; If none of these work, you'll need to set `conda-anaconda-home' yourself.
;;
;; Once set, run M-x `conda-env-activate' to switch between environments OR turn
;; on `conda-env-autoactivate-mode' if you want it done automatically.
