See the -;; GNU General Public License for more details. - -;; You should have received a copy of the GNU General Public License -;; along with this program. If not, see . - - -;;; Commentary: - -;; This is a "rainbow parentheses" mode which includes support for -;; parens "()", brackets "[]", and braces "{}". It conveys nesting depth -;; by using a different color for each successive nested set of -;; delimiters. It highlights all statements at a given level using the -;; same color - if several statements are all at the same depth, they -;; will all be the same color. -;; -;; Great care has been taken to make this mode FAST. You should see no -;; discernible change in scrolling or editing speed while using it, -;; even with delimiter-rich languages like Clojure, Lisp, and Scheme. -;; -;; The ultimate goal for the mode is to be useful with a wide variety -;; of programming languages with optional semantics catered to each. -;; -;; Default colors are subtle, with the philosophy that it's better to -;; avoid being visually intrusive. Color schemes are always a matter of -;; taste. If you take the time to design a new color scheme, please -;; share it (a plain-text list of colors is fine) on the EmacsWiki page! -;; URL: http://www.emacswiki.org/emacs/RainbowDelimiters - - -;;; Installation: - -;; 1. Place rainbow-delimiters.el on your emacs load-path. -;; -;; 2. Compile the file (necessary for speed): -;; M-x byte-compile-file -;; -;; 3. Add the following to your dot-emacs/init file: -;; (require 'rainbow-delimiters) -;; -;; 4. Add hooks for modes where you want it enabled, for example: -;; (add-hook 'clojure-mode-hook 'rainbow-delimiters-mode) -;; -;; - To activate rainbow-delimiters mode temporarily in a buffer: -;; M-x rainbow-delimiters-mode -;; -;; 5. When using a dark background, if delimiter colors seem washed out -;; you may need to add the following to your dot-emacs and restart: -;; (setq-default 'frame-background-mode 'dark) -;; -;; This is because Emacs can guess frame-background-mode incorrectly, -;; causing rainbow-delimiters to use its light color scheme on dark -;; backgrounds. -;; -;; The light/dark color schemes differ only in their brightness level. - -;;; Customization: - -;; To customize various options, including the color scheme: -;; M-x customize-group rainbow-delimiters -;; -;; color-theme.el users: -;; If you use the color-theme package, you can specify custom colors -;; by adding the appropriate faces to your theme. -;; - Faces take the form of: -;; 'rainbow-delimiters-depth-#-face' with # being the depth. -;; Depth begins at 1, the outermost color. -;; Faces exist for depths 1-9. -;; - The unmatched delimiter face (normally colored red) is: -;; 'rainbow-delimiters-unmatched-face' - - -;;; Change Log: - -;; 1.0 - Initial release. -;; 1.1 - Stop tracking each delimiter's depth independently. -;; This had lead to confusing results when viewing clojure -;; code. Instead, just color based on current nesting inside -;; all delimiters combined. -;; - Added 'all-delimiters' faces to apply a color scheme to -;; all delimiters at once. Other faces inherit from this group. -;; 1.1.1 - Change color scheme to a lighter, more subtle style. -;; 1.1.2: (2011-03-25) -;; - Add an unmatched-delimiter face and correct problem with -;; coloring of text following unmatched closing delims. -;; 1.2: (2011-03-28) -;; - Unify delimiter faces: all delimiter types now use the same depth -;; faces, of form 'rainbow-delimiters-depth-#-face'. -;; 1.2.1: (2011-03-29) -;; - Conform to ELPA conventions. -;; 1.3: (2011-05-24) -;; - Add separate light and dark color schemes. -;; - Checkboxes to enable/disable highlighting for each delimiter type. -;; - Improvements to Customize interface. -;; - Infinite depth support by cycling through defined faces repeatedly. -;; - Documentation changes. - -;;; TODO: - -;; - Add support for independent depth tracking for each delimiter type, -;; for users of C-like languages. -;; - Add Python support - highlighting parens according to indentation level. -;; - Add support for nested tags (XML, HTML) -;; - Set up proper example color-theme.el themes for rainbow-delimiters mode. -;; - Intelligent support for other languages: Ruby, et al. - -;;; Issues: - -;; - Rainbow-delimiters mode does not appear to change the color of -;; delimiters when Org-mode is also enabled. -;; - Some Emacs versions don't set frame-background-mode to dark automatically, -;; causing users of dark backgrounds to receive the wrong set of colors. -;;
