Night Owl for Emacs

Based entirely on Sarah Drasner's amazing Night Owl VSCode Theme. Built by modifying Kelvin Smith's monokai-emacs. Many thanks to both Sarah Drasner and Kelvin Smith.

Installation

If you're all set up to use MELPA, simply

M-x package-install RET night-owl-theme RET

Otherwise, ensure sure a directory containing these files is on your load-path.

Use M-x customize-themes to activate it, or put the following in your Emacs configuration file:

(load-theme 'night-owl t)

Status

Initial development, but covers most of my use cases. PRs gladly accepted.

Tips

Ivy

To style the non-selected ivy items, try this:

(defun night-owl/ivy-format-function-line (cands)
  "Transform CANDS into a string for minibuffer."
  (let ((str (ivy-format-function-line cands)))
    (font-lock-append-text-property 0 (length str) 'face 'ivy-not-current str)
    str))

(setq ivy-format-function #'night-owl/ivy-format-function-line)

Spacemacs/evil

To style spacemacs cursors, try this:

(setq night-owl-evil-cursors
      '(("normal" night-owl-orange box)
        ("insert" night-owl-cursor (bar . 2))
        ("emacs" night-owl-cursor (bar . 2))
        ("hybrid" night-owl-cursor (bar . 2))
        ("replace" night-owl-gray (hbar . 2))
        ("evilified" night-owl-yellow box)
        ("visual" night-owl-gray (hbar . 2))
        ("motion" night-owl-violet box)
        ("lisp" night-owl-red box)
        ("iedit" night-owl-magenta box)
        ("iedit-insert" night-owl-magenta (bar . 2))))

(defun night-owl-set-evil-cursor (state color shape)
  (set (intern (format "evil-%s-state-cursor" state))
       (list color shape)))

(defun night-owl-update-evil-cursors ()
  (let ((current-theme (symbol-name (car custom-enabled-themes))))
    (if (string-prefix-p "night-owl" current-theme)
        (cl-loop for (state color style) in night-owl-evil-cursors
                 do
                 (night-owl-set-evil-cursor state (symbol-value color) style))
      ;; not night-owl theme, restore default spacemacs cursors
      (if (functionp 'spacemacs/add-evil-cursor)
          (cl-loop for (state color shape) in spacemacs-evil-cursors
                   do (spacemacs/add-evil-cursor state color shape))))))
