Customization can be done in 2 ways.
- Elisp code in a .viper file in your home directory. Viper
loads .viper just before it does the binding for mode
hooks. This is recommended for experts only.
- Elisp code in your .emacs file before and after the
'viper) line. This method is not recommended, unless you know what
you are doing. Only two variables,
viper-custom-file-name, are supposed to be customized in .emacs,
prior to loading Viper (i.e., prior to
(require 'viper) command.
- By executing the :customize Ex command. This takes you to the Emacs
customization widget, which lets you change the values of Viper
customizable variables easily. This method is good for novice and
experts alike. The customization code in the form of Lisp commands will be
placed in ~/.emacs or some other customization file depending on the
version of Emacs that you use. Still, it is recommended to separate
Viper-related customization produced by the Emacs customization widget
and keep it in the .viper file.
Some advanced customization cannot be accomplished this way, however, and
has to be done in Emacs Lisp in the .viper file. For the common
cases, examples are provided that you can use directly.
