@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{})))
