It is a fork from the brilliant rainbow-delimiters, base it, I develop the feature of emphasising delimiters of current cursor mode. Since I change too much of it, So I make a new repo to develop it.

You can install it manually, steps:

• download pair-colorizer.el
• put it into your load directory, ie: (add-to-list 'load-path "~/.emacs.d/xx/xx")
• (require 'pair-colorizer)

You can also use package-install-from-buffer to install it.

To toggle the pair-colorizer-mode in the current buffer:

M-x pair-colorizer-mode

At default, the pair-colorizer-emphasise is enable, if you don’t like it, you can turn it off by follows:

(custom-set-variables '(pair-colorizer-emphasise nil))

To start the mode automatically in most programming modes (Emacs 24 and above):

(add-hook 'prog-mode-hook #'pair-colorizer-mode)

You can set your own rainbow colors use:

;; for light background
(setq pair-colorizer-light-colors ["#xx" "#xx"])
;; for dark background
(setq pair-colorizer-dark-colors ["#xx" "#xx"])

You can also use customize-group to customize various options, including the color theme:

M-x customize-group <RET> pair-colorizer

You can specify faces by customizing following faces:

• The unmatched delimiter face: pair-colorizer-unmatched-face.
• The mismatched delimiter face: pair-colorizer-mismatched-face.

You can change the strategy of picking colorized face or emphasised face for a certain depth.

• To pick a face used to highlight a delimiter: pair-colorizer-pick-face-function
• To pick a face used to emphasise a delimiter of current cursor: pair-colorizer-emphasise-pick-face-function.

Below is my configuration.

(custom-set-variables '(pair-colorizer-emphasise t))
(custom-set-faces
 '(pair-colorizer-unmatched-face ((t (:foreground "#ff5370" :inverse-video t :weight bold))))
 '(pair-colorizer-mismatched-face ((t (:inherit pair-colorizer-unmatched-face))))

(setq pair-colorizer-dark-colors
      ["#c792ea" "#f78c6c" "#c3e88d" "#89DDFF" "#bb80b3"
       "#ffcb6b" "#82aaff" "#44b9b1" "#80cbc4"])

Hope it will help you!

And I’ll appreciate it if you can star this repo.

If you have any bugs, please issue it, help me make it better!
