Use a different theme when publishing Org files

I've been using material-theme lately, and I sometimes switch around, but I've found that solarized produces the best exported code block results. To avoid having to remember to switch themes when exporting, I wrote a quick wrapper for org-export to do it for me:

  (defun my/with-theme (theme fn &rest args)
    (let ((current-themes custom-enabled-themes))
      (mapcar #'disable-theme custom-enabled-themes)
      (load-theme theme t)
      (let ((result (apply fn args)))
        (mapcar #'disable-theme custom-enabled-themes)
        (mapcar (lambda (theme) (load-theme theme t)) current-themes)
        result)))

  (advice-add #'org-export-to-file :around (apply-partially #'my/with-theme 'solarized-dark))
  (advice-add #'org-export-to-buffer :around (apply-partially #'my/with-theme 'solarized-dark))

Voilà, no more bizarrely formatted code block exports from whatever theme I might have loaded at the time :)
