@subsubheading Dictionary Service
@cindex dictionary service, for Home
The @code{(gnu home services dict)} module provides the following service:
@defvar home-dicod-service-type
This is the type of the service that runs the @command{dicod} daemon, an
implementation of DICT server (@pxref{Dicod,,, dico, GNU Dico Manual}).
You can add @command{open localhost} to your @file{~/.dico} file to make
@code{localhost} the default server for @command{dico} client
(@pxref{Initialization File,,, dico, GNU Dico Manual}).
@end defvar
This service is a direct mapping of the @code{dicod-service-type} system
service (@pxref{Miscellaneous Services, Dictionary Service}). You can
use it like this:
@lisp
(service home-dicod-service-type)
@end lisp
You may specify a custom configuration by providing a
@code{dicod-configuration} record, exactly like for
@code{dicod-service-type}, but wrapping it in @code{for-home}:
@lisp
(service home-dicod-service-type
(for-home
(dicod-configuration @dots{})))
