I have installed leuven with melpa a while ago and updated it as of 31st of August 2019. I found out there is a dark version. How do I activate it at loading of Emacs? I have tried:
(add-to-list 'custom-theme-load-path " ~/.emacs.d/elpa/leuven-theme-20190831.1008/")
(load-theme 'leuven-dark t)
Note that (load-theme 'leuven t) works for the light version. I have tried comparing leuven-theme.el and leuven-dark-theme.el but could not find a clue about what I am doing wrong.
