gettext: The --style option

 
 9.11.3 The ‘--style’ option
 ---------------------------
 
    The ‘--style=STYLE_FILE’ option specifies the style file to use when
 colorizing.  It has an effect only when the ‘--color’ option is
 effective.
 
    If the ‘--style’ option is not specified, the environment variable
 ‘PO_STYLE’ is considered.  It is meant to point to the user’s preferred
 style for PO files.
 
    The default style file is
 ‘$prefix/share/gettext/styles/po-default.css’, where ‘$prefix’ is the
 installation location.
 
    A few style files are predefined:
 ‘po-vim.css’
      This style imitates the look used by vim 7.
 
 ‘po-emacs-x.css’
      This style imitates the look used by GNU Emacs 21 and 22 in an X11
      window.
 
 ‘po-emacs-xterm.css’
 ‘po-emacs-xterm16.css’
 ‘po-emacs-xterm256.css’
      This style imitates the look used by GNU Emacs 22 in a terminal of
      type ‘xterm’ (8 colors) or ‘xterm-16color’ (16 colors) or
      ‘xterm-256color’ (256 colors), respectively.
 
 You can use these styles without specifying a directory.  They are
 actually located in ‘$prefix/share/gettext/styles/’, where ‘$prefix’ is
 the installation location.
 
    You can also design your own styles.  This is described in the next
 section.
