gnus: Smileys

 
 9.14.3 Smileys
 --------------
 
 “Smiley” is a package separate from Gnus, but since Gnus is currently
 the only package that uses Smiley, it is documented here.
 
    In short—to use Smiley in Gnus, put the following in your
 ‘~/.gnus.el’ file:
 
      (setq gnus-treat-display-smileys t)
 
    Smiley maps text smiley faces—‘:-)’, ‘8-)’, ‘:-(’ and the like—to
 pictures and displays those instead of the text smiley faces.  The
 conversion is controlled by a list of regexps that matches text and maps
 that to file names.
 
    The alist used is specified by the ‘smiley-regexp-alist’ variable.
 The first item in each element is the regexp to be matched; the second
 element is the regexp match group that is to be replaced by the picture;
 and the third element is the name of the file to be displayed.
 
    The following variables customize the appearance of the smileys:
 
 ‘smiley-style’
      Specifies the smiley style.  Predefined smiley styles include
      ‘low-color’ (small 13x14 pixel, three-color images), ‘medium’ (more
      colorful images, 16x16 pixel), and ‘grayscale’ (grayscale images,
      14x14 pixel).  The default depends on the height of the default
      face.
 
 ‘smiley-data-directory’
      Where Smiley will look for smiley faces files.  You shouldn’t set
      this variable anymore.  Customize ‘smiley-style’ instead.
 
 ‘gnus-smiley-file-types’
      List of suffixes on smiley file names to try.
