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.
