+
+The @uref{https://tiswww.cwru.edu/php/chet/readline/rltop.html, GNU
+Readline package} includes Emacs and vi editing modes, with the ability
+to customize the configuration with settings in the @file{~/.inputrc}
+file. With the @code{gnu home services shells} module, you can setup
+your readline configuration in a predictable manner, as shown below.
+For more information about configuring an @file{~/.inputrc} file,
+@pxref{Readline Init File,,, readline, GNU Readline}.
+
+@defvar home-inputrc-service-type
+
+This is the service to setup various @file{.inputrc} configurations. The
+settings in @file{.inputrc} are read by all programs which are linked
+with GNU Readline.
+
+Here is an example of a service and its configuration that you could add
+to the @code{services} field of your @code{home-environment}:
+
+@lisp
+(service home-inputrc-service-type
+ (home-inputrc-configuration
+ (key-bindings
+ `(("Control-l" . "clear-screen")))
+ (variables
+ `(("bell-style" . "visible")
+ ("colored-completion-prefix" . #t)
+ ("editing-mode" . "vi")
+ ("show-mode-in-prompt" . #t)))
+ (conditional-constructs
+ `(("$if mode=vi" .
+ ,(home-inputrc-configuration
+ (variables
+ `(("colored-stats" . #t)
+ ("enable-bracketed-paste" . #t)))))
+ ("$else" .
+ ,(home-inputrc-configuration
+ (variables
+ `(("show-all-if-ambiguous" . #t)))))
+ ("endif" . #t)
+ ("$include" . "/etc/inputrc")
+ ("$include" . ,(file-append
+ (specification->package "readline")
+ "/etc/inputrc"))))))
+@end lisp
+
+The example above starts with a combination of @code{key-bindings} and
+@code{variables}. The @code{conditional-constructs} show how it is
+possible to add conditionals and includes. In the example above
+@code{colored-stats} is only enabled if the editing mode is @code{vi}
+style, and it also reads any additional configuration located in
+@file{/etc/inputrc} or in @file{/gnu/store/@dots{}-readline/etc/inputrc}.
+
+The value associated with a @code{home-inputrc-service-type} instance
+must be a @code{home-inputrc-configuration} record, as described below.
+
+@end defvar
+
+@anchor{home-inputrc-configuration}
