3 Customization
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
(require 'viper) line. This method is
not recommended, unless you know what you are doing.
Only two variables, viper-mode and
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.
