+@subsection Sway window manager
+@cindex Sway, Home service
+
+The @code{(gnu home services sway)} module provides
+@code{home-sway-service-type}, a home service to configure sway in a
+declarative way.
+
+@quotation Note
+This home service only sets up configuration file and profile packages
+for sway. It does @i{not} start sway in any way. If you want to do so,
+you might be interested in using @code{greetd-wlgreet-sway-session}
+instead.
+
+The function @code{sway-configuration->file} defined below can be used
+to provide the value for the @code{sway-configuration} field of
+@code{greetd-wlgreet-sway-session}.
+@end quotation
+
+@defvar sway-configuration->file
+This function takes a @code{sway-configuration} record (defined below),
+and returns a file-like object represented the serialized configuration.
+@end defvar
+
+@defvar home-sway-service-type
+This is a home service type to set up Sway. It takes care of:
+@itemize
+@item
+providing a @file{~/.config/sway/config} file,
+@item
+adding sway-related packages to your profile.
+@end itemize
+
+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
+(define bg-file
+ (computed-file
+ "background.png"
+ #~(let* ((insvg (string-append
+ #$guix-backgrounds
+ "/share/backgrounds/guix/guix-checkered-16-9.svg"))
+ (out #$output)
+ (cmd (string-append
+ #$librsvg "/bin/rsvg-convert " insvg " -o " out)))
+ (system cmd))))
+
+(service home-sway-service-type
+ (sway-configuration
+ (gestures
+ '((swipe:3:down . "move to scratchpad")
+ (swipe:3:up . "scratchpad show")))
+ (outputs
+ (list (sway-output
+ (identifier '*)
+ (bg bg-file))))))
+@end lisp
+
+The above example describes a sway configuration in which
+@itemize
+@item
+all monitors use a particular wallpaper whose @file{.svg} is provided by
+the @code{guix-background} package;
+@item
+swiping down (resp.@ up) with three fingers moves the active window to
+the scratchpad (resp.@ shows/hides the scratchpad).
+@end itemize
+@end defvar
+
+
+@deftp {Data Type} sway-configuration
+This configuration record describes the sway configuration
+(see@ @cite{sway(5)}). Available fields are:
+
+@table @asis
+@item @code{variables} (default: @code{%sway-default-variables})
+The value of this field is an association list in which keys are symbols
+and values are strings.
+
+Example: @code{'(mod . "Mod4")}.
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+The value of this field is an association list in which keys are symbols
+and values are strings or G-expressions (@pxref{G-Expressions}).
+
+Examples using:
+@itemize
+@item
+a string: @code{'($mod+Return . "exec $term")}
+@item
+a G-exp: @code{`($mod+t . ,#~(string-append #$st "/bin/st"))}
+@end itemize
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+This value of this field is an association list, as for keybindings.
+
+@item @code{packages} (default: @code{%sway-default-packages})
+This field describes a list of packages to add to the user profile.
+
+@item @code{inputs} (default: @code{(list (sway-input))})
+List of @code{sway-input} configuration records.
+
+@item @code{outputs} (default: @code{'()})
+List of @code{sway-output} configuration records.
+
+@item @code{bar} (default: @code{(sway-bar)})
+Bar configuration.
+
+@item @code{always-execs} (default: @code{'()})
+Programs to execute at startup time @i{and} after every configuration
+reload. The value of this field is a list of strings or G-expressions.
+
+@item @code{execs} (default: @code{'()})
+Programs to execute at startup time. The value of this field is a list
+of strings or G-expressions.
+
+@item @code{extra-content} (default: @code{'()})
+Lines to add to the configuration file. The value of this field is a
+list of strings or G-expressions.
+
+@end table
+@end deftp
+
+@deftp {Data Type} sway-input
+@code{sway-input} records describe input blocks
+(see@ @cite{sway-input(5)}). Available fields are:
+
+@table @asis
+@item @code{identifier} (default: @code{'*})
+Identifier of the input. The field accepts symbols and strings. If a
+string is used, it will be quoted in the generated configuration file.
+
+@item @code{xkb-layout} (optional)
+Keyboard specific option. Comma-separated keyboard layout(s) to use.
+
+@item @code{xkb-model} (optional)
+Keyboard specific option. String providing the keyboard model.

+Keyboard specific option. Additional xkb options for the keyboard.
+
+@item @code{xkb-variant} (optional)
+Keyboard specific option. String specifying the variant of the layout.
+
+@item @code{extra-content} (default: @code{'()})
+Lines to add to the input block. The value of this field is a list of
+strings or G-expressions.
+
+@end table
+
+For example, the following snippet makes all keyboards use a french
+layout, in which @kbd{capslock} has been remaped to @kbd{ctrl}:
+@lisp
+(sway-input (identifier "type:keyboard")
+ (xkb-layout "fr")
+ (xkb-options '("ctrl:nocaps")))
+@end lisp
+@end deftp
+

+it will be quoted in the configuration file.

+@item @code{resolution} (optional)
+This string defines the resolution of the monitor.
+
+@item @code{position} (optional)
