How would I go about using my own fork of some core packages in spacemacs? So for example I'd like to use my own fork of spaceline, but I would like to keep the modifications that spacemacs does for it.
I tried doing this in
(setq spacemacs-modeline-packages '( anzu fancy-battery ;; dependency of spaceline-all-the-icons which came from ;; the emacs wiki, we fetch it from Emacs Mirror for now. ;; TODO eventually remove this if font-lock+ is available ;; in an ELPA repository. (font-lock+ :step pre :location (recipe :fetcher github :repo emacsmirror/font-lock-plus)) neotree (spaceline :location local) (spaceline-all-the-icons :location local) symon (vim-powerline :location local) ))
and symlinked the local copy of my forks to spaceline and spaceline-all-the-icons to the local folder, but it just uninstalled all the packages related to those and gave me errors about undefined functions
