Rainbow-delimiters is a "rainbow parentheses"-like mode for Emacs which highlights parentheses, brackets, and braces according to their depth. Each successive level is highlighted in a different color, making it easy to spot matching delimiters, orient yourself in the code, and tell which statements are at a given level.

This package provides the auto-dark-mode minor mode, which enables automatic switching between two user-defined (customizable) themes. This transition occurs seamlessly in response to dark mode being enabled or disabled in the desktop preferences (such as in GNOME). It uses DBus to query the system configured value. To enable it, put the following snippet to your Emacs configuration file:

(require auto-dark)
(auto-dark-mode t)

To customize the themes used, visit M-x customize-group auto-dark.

This simple Emacs minor mode allows you to toggle a window's "dedicated" flag. When a window is "dedicated", Emacs will not select files into that window. This can be quite handy since many commands will use another window to show results (compilation mode, starting info, and so on). A dedicated window won't be used for such a purpose. For details, please read the source file.
