13.3 Home Services

A home service is not necessarily something that has a daemon and is managed by Shepherd (veja Jump Start em The GNU Shepherd Manual), in most cases it doesn’t. It’s a simple building block of the home environment, often declaring a set of packages to be installed in the home environment profile, a set of config files to be symlinked into XDG_CONFIG_HOME (~/.config by default), and environment variables to be set by a login shell.

There is a service extension mechanism (veja Composição de serviço) which allows home services to extend other home services and utilize capabilities they provide; for example: declare mcron jobs (veja GNU Mcron) by extending Scheduled User’s Job Execution; declare daemons by extending Managing User Daemons; add commands, which will be invoked on by the Bash by extending home-bash-service-type.

A good way to discover available home services is using the guix home search command (veja Invoking guix home). After the required home services are found, include its module with the use-modules form (veja Using Guile Modules em The GNU Guile Reference Manual), or the #:use-modules directive (veja Creating Guile Modules em The GNU Guile Reference Manual) and declare a home service using the service function, or extend a service type by declaring a new service with the simple-service procedure from (gnu services).
