viper: Customization
3 Customization
***************
Customization can be done in 2 ways.
• Elisp code in a ‘~/.emacs.d/viper’ (or ‘~/.viper’) file. Viper
loads this file 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 your
Viper customization file.
Some advanced customization cannot be accomplished this way,
however, and has to be done in Emacs Lisp in your Viper
customization file. For the common cases, examples are provided
that you can use directly.
