+@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{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
+

+@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

+ '((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))})

+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:

+@subsection Sway window manager
+
+@cindex sway, configuration
+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
+ #$librsvg "/bin/rsvg-convert " insvg " -o " out)))
+ (system cmd))))
+
+(service home-sway-service-type
+ (sway-configuration
+ (gestures
+ '((swipe:3:down . "move to scratchpad")
+ (swipe:3:up . "scratchpad show")))
+ (outputs
+ (list (sway-output
+ (identifier '*)
+ (bg bg-file))))))
+@end lisp
+
+The above example describes a sway configuration in which
+@itemize
+@item
+all monitors use a particular wallpaper whose @file{.svg} is provided by
+the @code{guix-background} package;
+@item
+swiping down (resp.@ up) with three fingers moves the active window to
+the scratchpad (resp.@ shows/hides the scratchpad).
+@end itemize
+@end defvar
+
+
+@deftp {Data Type} sway-configuration
+This configuration record describes the sway configuration
+(see@ @cite{sway(5)}). Available fields are:
+
+@table @asis
+@item @code{variables} (default: @code{%sway-default-variables})
+The value of this field is an association list in which keys are symbols
+and values are strings or G-expressions (@pxref{G-Expressions}).
+
+Example: @code{'(mod . "Mod4")}.
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+This field describes keybindings for the @emph{default} mode. As above,
+the value is an association list: keys are symbols and values are either
+strings or G-expressions.
+
+@c @example
+Examples using:
+@itemize
+@item
+a string: @code{'($mod+Return . "exec $term")}
+@item
+a G-exp: @code{`($mod+t . ,#~(string-append #$st "/bin/st"))}
+@end itemize
+@c @end example
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+Similar to the previous field, but for finger-gestures.
+
+@c @example
+The following snippet allows to navigate through workspaces by swiping
+right and left with three fingers:
+@lisp
+`((swipe:3:right . "workspace next_on_output")
+ (swipe:3:left . "workspace prev_on_output"))
+@end lisp
+@c @end example
+
+@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{%sway-default-execs})
+Programs to execute at startup time. The value of this field is a list

+@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.

+@item @code{xkb-options} (optional)
+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.

+@table @asis
+@item @code{identifier} (default: @code{'*})
+Identifier of the monitor. If the
+@code{identifier} is a symbol, it is inserted as is; if it is a string,
+it will be quoted in the configuration file.
+
+@item @code{resolution} (optional)
+This string defines the resolution of the monitor.
+
+@item @code{position} (optional)
+The (optional) value of this field must be a @code{point}.
+Example:
+@lisp

+ (point (x 1920)
+ (y 0)))
+@end lisp
+
+@item @code{bg} (optional)
+This field accepts a file-like value representing the wallpaper to use
+on this monitor. It will be used with the @code{fill} option.
+
+@item @code{extra-content} (default: @code{'()})
+Any additional lines to be added to the output configuration block.
+Elements of the list must be either strings or G-expressions.

Thank you Arnaud for this well-written home-sway-service!
Some comments for you or the one who pushes your patch. I would
rather not take any responsibility for sway myself.

Good. Even though it is a little strange that one would add a home
module (gnu home services sway) to the operating-system configuration,
I know no better place for this `sway-configuration->file' procedure,
since the record is for Guix Home and being able to use it for greetd
is just an extra feature.

Why not (bg #~(file-append #$guix-backgrounds
"\
/share/backgrounds/guix/guix-checkered-16-9.svg"))
? This does not work right now, but could you change bg and
perhaps status-command to accept gexps?

Should be with a colon: resp.@: up
You should run untabify on all of gnu/home/services/sway.scm
to get rid of nasty tabs.
Otherwise looks really good to me (although I have not cross-checked
the man pages).

Florian

this does not put a comma between each element of xkb-options.

Hi Florian,
Thank you for your review. I will submit a v5 soon to take your remarks
into account and add an additional configuration field (to easily add
modes, e.g. the resize mode).

Yes, I agree; I could not find a better place for this function either.
Do you think that this note is helpful, or should I remove it?

Hello Arnaud. I’m still looking at the details of sway, so I could
myself push your patch with confidence to guix.git, but would also be
happy if others pushed it. I am already using it on my family’s media
PC now [1]. Thank you for it!

That one can use your `sway-configuration' enables one to configure the
inputs field declaratively to use another keyboard layout in the
greeter. It is a good feature. But perhaps add the word “optionally”
to make clear users do not have to provide a sway-configuration to the
greeter.

Now that I tested this code, I notice that SVG backgrounds work only
if and only if librsvg is found. Still, I think it is better this way
with file-append. Perhaps add a note to doc/guix.texi here that this
librsvg must be installed or propagated in the packages field.

These fields are missing a colon “default: ”. In other places you
correctly write “default: ”.

Hello Florian and Hilton,
Thank you for your words and reviews! It is nice to know that a few
people are interested :).
> I’m still looking at the details of sway, so I could myself push your
> patch with confidence to guix.git, but would also be happy if others
> pushed it
Nice, NB: it is also fine
Upon reading the code again, one point is still unclear: the list of
packages that I include in user profiles seems a bit random :/.
- sway, swaylock and swaybg: useful to launch some commands manually
(including swaymsg).
- waybar, dmenu and bemenu: do not seem necessary. I will probably
remove them.
- dbus, xdg-desktop-portal and xdg-desktop-portal-wlr: may be
interesting to have. On my laptop, screen sharing¹ only works when
xdg-desktop-portal and xdg-desktop-portal-wlr are in the same profile²
(associated executable files end up in ~/.guix-home/profile/libexec/).
¹: I do not have a fully functional setup
for screen sharing yet (it does not work
in all web browsers). I (or someone else)
should probably add elements in the
default `execs' / `always-execs' fields
if/when they have a working setup later.
NB: this should not be a road blocker for
the current patch IMHO.
²: I do not know if that is a hard
requirement or if my issues are related to
something else.
- slurp and grim: screenshots (+ screen selection when screen sharing).
I will probably define a new variable `%sway-default-packages'
containing the above packages (minus waybar, ...). WDYT?

Yes indeed. In the v6, I will try to make a few fields optional, and
also avoid empty groups in produced configuration file.

Indeed; I will try to phrase this properly.

I will add a note in the next version of the doc, to hint towards the
two solutions to use a svg file: adding librsvg to the profile, or
computing the png and put it in the store using a "computed-file" in the
configuration (as in the second version of the patch).

Yes, good idea.
Though some of these commands like dbus and xdg portals are unnecessary
because noone will run them manually from within sway.
Also note that the menu should default to wmenu instead of dmenu
according to swaywm.org release notes for current sway 1.9. Both are in
$(guix build sway)/etc/sway/config, but dmenu got used, but probably for
compatibility only.
wmenu should be the only menu.
Do we have an API stability guarantee that `%sway-default-packages' will
remain the same? I guess we better try not to remove packages from it
in the future but get it right from the start.

Do we need a computed-file example? Sway’s default background
$(guix build sway)/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png
is a .png file already. We need not use guix-backgrounds. Rationale:
In the computed-file version, note that librsvg needs rust and rust does
not build on i686-linux nor armhf. I tested in an i686-linux VM and the
rest of your home-sway-service-type works great there (using elogind and
manually running sway, because greetd would need rust). Using
imagemagick’s convert just gives a bogus pure black .png file.
I still have not found the time to look at `sway-bar' and `point' and
`sway-color' and such details.
Regards,
Florian

I meant: it is also fine if you prefer to wait a few weeks for someone
else with commit access to comment/push this patch (as I do not want to
put pressure on you, and you said that you preferred not to take
responsibility for sway in a previous email).

As I have changed these configuration records and the serialisation
function (hopefully making it easier to read and modify) in the v6, I
will send it today. I will not address your comments from today, but
should contain improvements over the previous code.

Yes, indeed. This week, I will test sway with only (list sway) and
(list sway swaybg) to see what works and what fails in each case. Then,
I will try to minimise the list of v5 (as users can always provide their
own lists if they want more packages to be available).

Noted. I used an outdated default sway configuration when defining
default variables, my bad.
This will not be modified in the v6 (as I send it right away), but
should be done later; I have added a comment in the code to remind me of
that.

Indeed, this would be better. As mentioned above, I will try to
minimise this list and only keep packages that are necessary for using
sway. I will try to report on that within the week.

Thank you for this thorough testing and associated explanation.
I agree with you and have removed this example from the documentation
(only leaving the note that librsvg is needed in the profile in order to
use svg files).

Thank you. There’s no pressure on me, but I will be slow in my
investigation and responses.

Sorry, I had not tested this yet. Even though web searches point to
some obscure program called wmenu_path that must exist somewhere, it
seems your use of dmenu_path is what upstream uses. I do not really
understand this.

+@cindex sway, Home Service
+@cindex sway, configuration
+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 the 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
+(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 (file-append guix-backgrounds
+ "\
+/share/backgrounds/guix/guix-checkered-16-9.svg")))))))
+@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 or G-expressions (@pxref{G-Expressions}).
+
+Example: @code{'(mod . "Mod4")}.
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+This field describes keybindings for the @emph{default} mode. As above,
+the value is an association list: keys are symbols and values are either
+strings, G-expressions or file-append objects.
+
+Examples using:
+@itemize
+@item
+a string: @code{'($mod+Return . "exec $term")}
+@item
+a G-exp: @code{`($mod+t . ,#~(string-append #$st "/bin/st"))}
+@item
+a file-append: @code{`($mod+t . ,(file-append st "/bin/st"))}
+@end itemize
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+Similar to the previous field, but for finger-gestures.
+
+The following snippet allows to navigate through workspaces by swiping
+right and left with three fingers:
+@lisp
+'((swipe:3:right . "workspace next_on_output")
+ (swipe:3:left . "workspace prev_on_output"))
+@end lisp
+
+@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{modes} (default: @code{'()})
+Optional list of @code{sway-mode} records (described below).
+
+@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{%sway-default-execs})
+Programs to execute at startup time. The value of this field is a list
+of strings or G-expressions.
+
+The default value, @code{%sway-default-execs}, executes @code{swayidle}
+in order to lock the screen after 5@ minutes of inactivity (displaying a
+background distributed with Sway) and turn of the screen after
+10@ minutes of inactivity.
+
+@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.
+@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
+
+@deftp {Data Type} sway-output
+@code{sway-output} records describe sway outputs
+(see@ @cite{sway-output(5)}). Available fields are:
+
+@table @asis
+@item @code{identifier} (default: @code{'*})
+Identifier of the monitor. If the
+@code{identifier} is a symbol, it is inserted as is; if it is a string,
+it will be quoted in the configuration file.
+
+@item @code{resolution} (optional)
+This string defines the resolution of the monitor.
+
+@item @code{position} (optional)
+The (optional) value of this field must be a @code{point}.
+Example:

+ (y 0)))
+@end lisp
+
+@item @code{bg} (optional)
+This field accepts a file-like value representing the wallpaper to use
+on this monitor. It will be used with the @code{fill} option.
+
+@item @code{extra-content} (default: @code{'()})
+Any additional lines to be added to the output configuration block.
+Elements of the list must be either strings or G-expressions.

I only send this version of the patch to provide the latest version of
my code.
I have checked that a few produced configuration files were valid sway
files (with "sway -c"), but have not yet performed further testing on
this version.
Note: I have not proof-read the documentation; it might be a little
behind on the code or contain misspellings.

+
+@cindex sway, Home Service
+@cindex sway, configuration
+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 the 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 @emph{optional} @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
+(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 (file-append sway
+ "\
+/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png")))))))
+@end lisp
+
+The above example describes a sway configuration in which
+@itemize
+@item
+all monitors use a particular wallpaper whose @file{.png} is provided by
+the @code{sway} 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 or G-expressions (@pxref{G-Expressions}).
+
+Example: @code{'(mod . "Mod4")}.
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+This field describes keybindings for the @emph{default} mode. As above,
+the value is an association list: keys are symbols and values are either
+strings, G-expressions or file-append objects.
+
+Examples using:
+@itemize
+@item
+a string: @code{'($mod+Return . "exec $term")}
+@item
+a G-exp: @code{`($mod+t . ,#~(string-append #$st "/bin/st"))}
+@item
+a file-append: @code{`($mod+t . ,(file-append st "/bin/st"))}
+@end itemize
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+Similar to the previous field, but for finger-gestures.
+
+The following snippet allows to navigate through workspaces by swiping
+right and left with three fingers:
+@lisp
+'((swipe:3:right . "workspace next_on_output")
+ (swipe:3:left . "workspace prev_on_output"))
+@end lisp
+
+@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 of @code{sway-input} configuration records.
+
+@item @code{outputs} (default: @code{'()})
+List of @code{sway-output} configuration records.
+
+@item @code{bar} (optional)
+Optional @code{sway-bar} configuration record to declare the sway-bar
+configuration.
+
+@item @code{modes} (default: @code{'()})
+Optional list of @code{sway-mode} records (described below).
+
+@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{%sway-default-execs})
+Programs to execute at startup time. The value of this field is a list
+of strings or G-expressions.
+
+The default value, @code{%sway-default-execs}, executes @code{swayidle}
+in order to lock the screen after 5@ minutes of inactivity (displaying a
+background distributed with Sway) and turn of the screen after
+10@ minutes of inactivity.
+
+@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)}). 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
+
+Available fields for @code{sway-input} configuration records 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. String providing a comma-separated keyboard
+layout(s) to use.
+
+@item @code{xkb-model} (optional)
+Keyboard specific option. String providing the keyboard model.
+
+@item @code{xkb-options} (optional)
+Keyboard specific option. List of strings specifying 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.
+@end table
+@end deftp
+
+@deftp {Data Type} sway-output
+@code{sway-output} records describe sway outputs
+(see@ @cite{sway-output(5)}). Available fields are:
+
+@table @asis
+@item @code{identifier} (default: @code{'*})
+Identifier of the monitor. If the
+@code{identifier} is a symbol, it is inserted as is; if it is a string,
+it will be quoted in the configuration file.
+
+@item @code{resolution} (optional)
+This string defines the resolution of the monitor.
+
+@item @code{position} (optional)
+The (optional) value of this field must be a @code{point}.
+Example:
+@lisp
+(position
+ (point (x 1920)
+ (y 0)))
+@end lisp
+
+@item @code{bg} (optional)
+This field accepts a file-like value representing the wallpaper to use
+on this monitor. It will be used with the @code{fill} option.
+
+@quotation Note
+If you have @code{librsvg} in your profile, it is possible to specify
+the path to an SVG file.
+@end quotation
+
+@item @code{extra-content} (default: @code{'()})
+List defining additional lines to add to the output configuration block.
+Elements of the list must be either strings or G-expressions.

+@end deftp
+
+@deftp {Data Type} sway-bar
+Describes the Sway bar (see@ @cite{sway-bar(5)}).
+
+@table @asis
+@item @code{identifier} (default: @code{'bar0})
+Identifier of the bar. The value must be a symbol.
+
+@item @code{position} (optional)
+Specify the position of the bar. Accepted values are @code{'top} or
+@code{'bottom}.
+
+@item @code{hidden-state} (optional)
+Specify the apparence of the bar when it is hidden. Accepted values are
+@code{'hide} or @code{show}.
+
+@item @code{binding-mode-indicator} (optional)
+Boolean enabling or disabling the binding mode indicator.
+
+@item @code{colors} (optional)
+An optional @code{sway-color} configuration record.
+
+@item @code{status-command} (default: @code{%sway-status-command})
+This field accept strings, G-expressions and executable file-like
+values. The default value is a command (string) that prints the date
+and time every second.
+
+Each line printed on @code{stdout} by this command (or script) will be
+displayed on the status area of the bar.
+
+Below are a few examples using:
+@itemize
+@item
+a string: @code{"while date +'%Y-%m-%d %X'; do sleep 1; done"},
+@item
+a G-exp:
+@lisp
+#~(string-append "while "
+ #$coreutils "/bin/date"
+ " +'%Y-%m-%d %X'; do sleep 1; done")
+@end lisp
+@item
+an executable file:
+@lisp
+(program-file
+ "sway-bar-status"
+ (with-imported-modules
+ (source-module-closure
+ '((ice-9 format) (srfi srfi-19)))
+ #~(begin
+ (use-modules (ice-9 format)
+ (srfi srfi-19))
+ (let loop ()
+ (let* ((date (date->string
+ (current-date)
+ "~d/~m/~Y (~a) ~H:~M:~S")))
+ (format #t "~a~%~!" date)
+ (sleep 1)
+ (loop))))))
+@end lisp
+@end itemize
+
+@item @code{mouse-bindings} (default: @code{'()})
+This field accepts an associative list. Keys are integers describing
+mouse events. Values can be either strings, G-expressions or
+file-append objects.
+
+The module @code{(gnu home services sway)} exports constants
+@code{%ev-code-mouse-left}, @code{%ev-code-mouse-right} and
+@code{%ev-code-mouse-scroll-click} whose values are integers
+corresponding to left, right and scroll click respectively. For
+example, with the @code{`((,%ev-code-mouse-left . ,(file-append st
+"/bin/st")))}, left clicks in the status bar open the @code{st}
+terminal.
+@end table
+@end deftp
+
+@deftp {Data Type} sway-mode
+Describes a Sway mode. For example, the following snippet defines a
+mockup of the resize mode of the default Sway configuration:
+@example
+(sway-mode
+ (mode-name "resize")
+ (keybindings
+ '(($left . "resize shrink width 10px")
+ ($right . "resize grow width 10px")
+ ($down . "resize grow height 10px")
+ ($up . "resize shrink height 10px")
+ (Return . "mode \"default\"")
+ (Escape . "mode \"default\""))))
+@end example
+
+@table @asis
+@item @code{mode-name} (default: @code{"default"})
+Name of the mode. This field accepts strings.
+
+@item @code{keybindings} (default: @code{'()})
+This field describes keybindings. The value is an association list:
+keys are symbols and values are either strings or G-expressions, as
+above.
+
+@item @code{mouse-bindings} (default: @code{'()})
+Ditto, but keys are mouse events (integers). Constants
+@code{%ev-code-mouse-*} described above can be used as helpers to define
+mouse bindings.

I don’t use Sway myself but it looks like a welcome addition.
I trust Hilton’s comment here so here are some more superficial
comments.

To add more context:
“… to configure the @uref{https://github.com/swaywm/sway,Sway window
manager for Wayland} in a declarative way.”

Should be “@deffn {Procedure} sway-configuration->file config”.

Please avoid abbreviations. Maybe these fields could be called
‘startup+reload-programs’ and ‘startup-programs’?
> +The default value, @code{%sway-default-execs}, executes @code{swayidle}
Likewise, @code{%sway-default-startup-programs}?

Would it be possible here to reuse the <keyboard-layout> record
documented in
<https://guix.gnu.org/manual/devel/en/html_node/Keyboard-Layout.html>?
If it’s possible, that would provide a nicely consistent interface. If
there’s the need for an extra identifier, maybe you’ll still need
<sway-input>:
(sway-input (identifier "type:keyboard")
(layout (keyboard-layout "tr")))
WDYT?
> +@lisp
> +(program-file
> + "sway-bar-status"

‘with-imported-modules’ can be removed here because (ice-9 format) and
(srfi srfi-19) are provided by Guile itself.
That’s it for me!
Could you send updated patches?
Thank you!
Ludo’.

Hi all,
This version takes into account previous reviews (hoping that I did not
forget/break something). The modifications are mainly:
• fix a typo in the code: in the v6, execs was serialised in place of
always-execs,
• following your advice, I renamed abbreviations:
- bg → background
- execs → startup-programs
- always-execs → startup+reload-programs
• keyboard layouts are now specified with <keyboard-layout> records in
sway-input, as suggested. I have added a cross-reference to the
relevant section in the manual.
Note: (gnu home services sway) does not re-export keyboard-layout.
• the background field of sway-output now accepts pairs too, in order to
describe how the background should be displayed (fill the screen, at
the center of the screen, etc.)
• the list of default packages is simply (list sway)
• (flatten (map _ _)) with a homemade flatten is replaced by (flatmap _
_) with a homemade flatmap.
• the default terminal is now set to foot (as in the default config on
the sway 1.9)
• extra-content no longer allows file-append objects (which did not make
sense)
• new fields in sway-input

+
+@cindex sway, Home Service
+@cindex sway, configuration
+The @code{(gnu home services sway)} module provides
+@code{home-sway-service-type}, a home service to configure the
+@uref{https://github.com/swaywm/sway,Sway window manager for Wayland} in
+a declarative way.
+
+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-sway-service-type
+ (sway-configuration
+ (gestures
+ '((swipe:3:down . "move to scratchpad")
+ (swipe:3:up . "scratchpad show")))
+ (outputs
+ (list (sway-output
+ (identifier '*)
+ (bg (file-append sway
+ "\
+/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png")))))))
+@end lisp
+
+The above example describes a Sway configuration in which
+@itemize
+@item
+all monitors use a particular wallpaper whose @file{.png} is provided by
+the @code{sway} package;
+@item
+swiping down (resp.@: up) with three fingers moves the active window to
+the scratchpad (resp.@: shows/hides the scratchpad).
+@end itemize
+
+@quotation Note
+This home service only sets up the configuration file and profile
+packages for Sway. It does @emph{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 @emph{optional} @code{sway-configuration}
+field of @code{greetd-wlgreet-sway-session}.
+@end quotation
+
+@deffn {Procedure} sway-configuration->file config
+This function takes a @code{sway-configuration} record (defined below),
+and returns a file-like object representing the serialized
+configuration.
+@end deffn
+
+@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
+@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 either strings, G-expressions or file-append objects
+(@pxref{G-Expressions}).
+
+Example:
+@lisp
+(variables `((mod . "Mod4") ; string
+ (term ; file-append
+ . ,(file-append foot "/bin/foot"))
+ (term ; G-expression
+ . ,#~(string-append #$foot "/bin/foot"))))
+@end lisp
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+This field describes keybindings for the @emph{default} mode. The value
+is an association list: keys are symbols and values are either strings
+or G-expressions.
+
+The following snippet launches the terminal when pressing @kbd{$mod+t}
+and @kbd{$mod+Shift+t} (assuming that a variable @code{$term} is
+defined):
+@lisp
+`(($mod+t . ,#~(string-append "exec " #$foot "/bin/foot"))
+ ($mod+Shift+t . "exec $term"))
+@end lisp
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+Similar to the previous field, but for finger-gestures.
+
+The following snippet allows to navigate through workspaces by swiping
+right and left with three fingers:
+@lisp
+'((swipe:3:right . "workspace next_on_output")
+ (swipe:3:left . "workspace prev_on_output"))
+@end lisp
+
+@item @code{packages} (default: @code{%sway-default-packages})
+This field describes a list of packages to add to the user profile. At
+the moment, the default value only adds @code{sway} to the profile.
+
+@item @code{inputs} (default: @code{'()})
+List of @code{sway-input} configuration records (described below).
+
+@item @code{outputs} (default: @code{'()})

+to the Sway configuration (@i{e.g.}@: the ``resize'' mode of the default
+Sway configuration).
+
+@item @code{startup+reload-programs} (default: @code{'()})
+Programs to execute at startup time @emph{and} after every configuration
+reload. The value of this field is a list of strings, G-expressions or
+file-append objects (@pxref{G-Expressions}).
+
+@item @code{startup-programs} (default: @code{%sway-default-execs})
+Programs to execute at startup time. As above, values of this field are
+a list of strings, G-expressions or file-append objects.
+
+The default value, @code{%sway-default-execs}, executes @code{swayidle}
+in order to lock the screen after 5@ minutes of inactivity (displaying a
+background distributed with Sway) and turn the screen off after 10@
+minutes of inactivity.
+
+@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)}). For example, the following snippet makes all

+@deftp {Data Type} sway-mode
+Describes a Sway mode (see@ @cite{sway(5)}). For example, the following
+snippet defines a mockup of the resize mode of the default Sway
+configuration:
+@example
+(sway-mode
+ (mode-name "resize")
+ (keybindings
+ '(($left . "resize shrink width 10px")
+ ($right . "resize grow width 10px")
+ ($down . "resize grow height 10px")
+ ($up . "resize shrink height 10px")
+ (Return . "mode \"default\"")
+ (Escape . "mode \"default\""))))
+@end example
+
+@table @asis
+@item @code{mode-name} (default: @code{"default"})
+Name of the mode. This field accepts strings.
+
+@item @code{keybindings} (default: @code{'()})
+This field describes keybindings. The value is an association list:
+keys are symbols and values are either strings or G-expressions, as
+above.
+
+@item @code{mouse-bindings} (default: @code{'()})
+Ditto, but keys are mouse events (integers). Constants
+@code{%ev-code-mouse-*} described above can be used as helpers to define
+mouse bindings.

Hi Arnaud. I still have not tested nor reviewed all features, but
some comments:

After I added new packages to home-environment’s packages field,
dmenu_path does not list newly installed packages for me, because it
is a shell script which needs a program called stest in PATH.
Now the wmenu_path I talked about earlier appears to be an invention
by the OpenBSD people that does not need stest [1].
Perhaps for more hackability, we could deviate from upstream and put in
a call to guile with a Scheme script in a computed-file that opens a
pipe to/from wmenu and does the same as dmenu_path without cache only on
~/.guix-home/profile/bin.
Or change the dmenu_path program with `substitute' to use the absolute
file-name of stest.

Yes indeed. Do you think that the Guile script should replace all of
"$menu", or just the dmenu_path part?
On this topic, do you know if there is a built-in way to write
`find -maxdepth 1 ...' in Guile (without calling `readdir' manually)?

What is the rationale for restricting the menu to this directory (and
not all directories in
(filter directory-exists? (string-split (getenv "PATH") #\:))
?

I think that the Guile script might be simpler.
By `substitute', do you mean in the package definition? This does not
seem necessary, as people installing dmenu have stest in their profile.

The point-issue was introduced in the v6. I apologise for those issues
that I bring in new patches... Thank you for catching them!
In my local files, I have also switched from using `open-output-file' to
`call-with-output-file'¹ and reduced the number of redundant calls to
`make-string'.
¹: in previous patches, I never called
`close-port'.

All of "$menu", because it looks nicer? But I should not imply that
such deviation from upstream were necessary for getting your patch in.
Basically my issue was that dmenu_path did not work.
Indeed stest is part of the dmenu package, so when dmenu is installed to
the profile, dmenu_path would work. So a more upstream conformant
solution would be to just add the dmenu package to sway’s packages.
However, dmenu_path’s cache means that if we used dmenu_path like
upstream, it would never recognize changes to the installed packages.
OpenBSD opted for wmenu_path which is like dmenu_path without cache
and a guile script seems more appropriate for Guix’ defaults.

scandir from the (ice-9 ftw) module, I think.

All my graphical applications are in the home profile and non-graphical
programs will not be used and clutter wmenu. Do others put graphical
apps in the system profile? Perhaps so. But then non-graphical
coreutils would be in the wmenu as well. Hmm I am not sure and would be
fine with either.

If dmenu were installed in the sway-packages, substitute would not be needed.

It can wait.

No worries. I think that finding a better solution now would be better
(and should not delay this issue for too long). It would avoid opening
a second issue and delaying/forgetting the cache problem.

Yes, adding dmenu would work (minus your second point). However, to
rely on both wmenu and dmenu feels a little weird, especially since the
latter is only used for a bash script.
It seems that Sway recently switched[1] to a utility called wmenu-run
(C program shipped with the last version of wmenu) to get rid of their
dependency on dmenu.

Yes, this is a good point. I also agree that using a single script for
all of the menu would make it clearer and more maintainable.
For both these reasons, here is a draft proposal for a script that could
replace the current content of "$menu". As suggested, it uses `scandir'
and only focuses on packages of the "home profile".
--8<---------------cut here---------------start------------->8---
(define sway-menu
(computed-file
"sway-menu.scm"
#~(begin
(use-modules (ice-9 receive)
(ice-9 rdelim)
(ice-9 ftw)
(guix build utils))
(define (directory->files dir)
(define (executable-file? f)

;; explanation of `(zero? ...)'.

(with-directory-excursion dir
(scandir "." executable-file?)))
(let ((path (string-append (getenv "HOME")
"/.guix-home/profile/bin"))
(wmenu #$(file-append wmenu "/bin/wmenu"))
(swaymsg #$(file-append sway "/bin/swaymsg")))

(execl swaymsg swaymsg "exec"
(string-append path "/" choice))))))))

WDYT?

Hello Arnaud. I like a lot your sway-menu.scm. For testing, I’ve
changed
(define sway-menu
(computed-file
"sway-menu.scm"
to
(define sway-menu
(scheme-file
"sway-menu.scm"
to use it like this:
(sway-configuration
(variables
`((menu . ,#~(string-append
"guile " #$sway-menu))
Sorry for having proposed compiled-file previously. At first I had
thought a compiled sway-menu.go would be appropriate, created in a
computed-file, which invokes `guild compile` on the .scm code, but
apparently this is not useful. I do not know enough here and
gnu/services/shepherd.scm does it in the scm->go procedure.
Anyway, some feedback:
> (define (directory->files dir)
> (define (executable-file? f)
> ;; Cf. `(@@ (guix build utils) executable-file?)' for an
> ;; explanation of `(zero? ...)'.
This is a comment anyway, but one @ in (@ (guix build utils)
executable-file?) would be enough, since the executable-file?
predicate is exported.
> (and=> (stat f)
> (lambda (s)
To reduce clutter in the wmenu suggestions more, I’d prefer
(and=> (and (not (eq? (string-ref f 0) #\.))
(stat f))
(lambda (s)
> (not (or (zero? (logand (stat:mode s) #o100))

Better use @ instead of @@.

Even though I like to get suggestions only for
~/.guix-home/profile/bin, if you do not prepend path,
(execl swaymsg swaymsg "exec"
choice)))))))
then it will remain possible to write shell commands in wmenu such as
guix shell weston -- weston-flower
to run apps without installing them.
Thank you greatly, this will definitely become my menu and in my
opinion it is the best default.
Since you told me about wmenu-run, I also locally updated wmenu [1]
and tested the menu config
(menu . ,#~(string-append
#$wmenu "/bin/wmenu-run"))
which would also work, but in my opinion the suggestions are better
when tied to .guix-home/profile. The wmenu-run does not use exec but
a protocol called XDG_ACTIVATION_TOKEN. But I do not see an advantage
to it. It behaves like always.
I’d welcome if you, Arnaud, sent a patch calling your sway-menu script.
Also I’d be happy if more careful commiters would push it; I prefer to
restrict my commits to translation updates.
Also one more thing, in the commit message, you meant to write
flatmap instead of flatten.
Regards,
Florian

I will proof-read and re-test the whole patch soon, hoping to avoid
additional careless bugs on my end.
Also: given that you assisted me quite a lot, do you want me to add a
line in the commit message to express that you helped me write the patch
(such as "This patch was co-authored with Florian Pelz.", as in Guix
commit 9371cf2138711ea7305951d82c5cf0b36ac4d6f1)?
I will send a v8 as soon as I have both seen your answer and proof-read
the patch.
NB: I think that the v8 can be the last version of the patch. Thank you
for your help and for your patience :)!
> Sorry for having proposed compiled-file previously.
No problem. I actually meant `program-file' instead of `computed-file'
(which was incorrectly used in my previous email). This way, the
lowered object in the store will be executable, allowing to define the
menu directly like this¹:
--8<---------------cut here---------------start------------->8---
(define %sway-default-variables
`([...]
(menu . ,sway-menu)))
--8<---------------cut here---------------end--------------->8---
¹: In the next version of the patch, I allow any file-like object in
`string-ish' instead of file-append objects only, so that Sway
variables can be bound to anything that can be lowered into a file
(in additions to strings and G-expressions).

Thank you for the pointer, `scm->go' is an interesting function.
I experimented and bit and was able to compile the menu to byte-code
using a similar function. However, I do not know a way to compile to
native code in Guile. Hence, I will stick to `program-file'.

Yes; I removed the string-append here. (As ~/.guix-home/profile/bin is
supposed to be in the path, this should work properly).

It is nice that this works too.
NB: if you want, you can use `(file-append pkg "stuff")' instead of
`#~(string-append #$pkg "stuff")'.
I do not know much about the XDG_ACTIVATION stuff; only that it has to
do with focused clients on Wayland IIRC. In my menu, I use `swaymsg
exec -- [command]', which takes care of a few things as well, as
explained below.
--8<---------------cut here---------------start------------->8---
Note: pass the final command to swaymsg so that the resulting window can
be opened on the original workspace that the command was run on.
--8<---------------cut here---------------end--------------->8---
Source: commit c3353bb27317d294a91a8accec9a554ea392de04 of Sway. It
explains why the menu is piped to 'swaymg exec --'. (I have added the
"--" argument in the v8).

Not for my review; this would be unusual.
Normally scm->go is probably unneeded here, because guile will find the compiled
.go file. However program-file seems to add --no-auto-compile. Not
sure now.
> NB: I think that the v8 can be the last version of the patch.
Otherwise yes, though I would prefer if another committer read it
again and pushed it.
Another more thing. I try (bar (sway-bar)), but it prints an empty bar
configuration to .config/sway/config. In patch 6, you added
no-serialization. Did this break it?

Florian

I do not know why the flag --no-auto-compile is passed either.

Hmmm, I am not sure.
It is normal that `(sway-bar)' is an empty bar configuration (as all bar
fields are now optional or empty by default). However, no configuration
block should appear in the serialised configuration in this case.
Maybe you need to pass --fresh-auto-compile to Guile when executing your
test scripts (so that it does not trust its cache). I realised once
that when updating the module `(gnu home services sway)', my test files
would not be recompiled and old serialisation functions were used.
In v6, `serialize-bar' looks like
--8<---------------cut here---------------start------------->8---
(add-block* "bar [bar name]"
[possibly empty list L1]
[...]
[possibly empty list Ln])
--8<---------------cut here---------------end--------------->8---
Thus, if all lists `Li' are empty, this should not add any line to the
configuration file. (Except for the header "# Bar configuration.[...]",
as it is added in the main serialisation function).
In my current version of the patch, the header is also removed if
nothing follows. Currently (on my local files), `(sway-configuration
(bar (sway-bar)))' is serialised into the following:
--8<---------------cut here---------------start------------->8---
####################################
### Auto-generated configuration ###
####################################
# DO NOT EDIT MANUALLY.
# Variables.
############
[ ... default variables ... ]
# Keybindings.
##############
[ ... default keybindings ...]
# Gestures.
###########
[ ... default gestures ...]
# Programs to execute (at startup).
###################################
[ ... default startup programs ...]
--8<---------------cut here---------------end--------------->8---
and `(sway-configuration (bar (sway-bar (hidden-state 'show))))' is
serialised into:
--8<---------------cut here---------------start------------->8---
####################################
### Auto-generated configuration ###
####################################
# DO NOT EDIT MANUALLY.
# Variables.
############
[ ... ]
# Bar configuration.
####################
bar bar0 {
hidden_state show
}
# Keybindings.
##############
[ ... ]
# Gestures.
###########
[ ... ]
# Programs to execute (at startup).
###################################
[ ... ]
--8<---------------cut here---------------end--------------->8---
So at least, the v8 should behave as expected.

Ooops, the identifier is not written, of course.
(bar (sway-bar
(position 'top)))
is fine. Not sure what defaults are best.

Not sure if exported open-pipe* would be better. open-process is
checked in guile tests, but not exported, that is right. But maybe a

I think that in our use case, program-file is better, because it does
not require to call Guile explicitly in the Sway configuration (all we
care about is that the serialised script "behaves like a menu program").

Yes, this is arbitrary in my code. Rationale behind my choice:
At first, I wanted to make the default value match that of the default
Sway configuration file. However, this would force some fields to be
mandatory (namely status-command, colors and position). As users may
not want to specify these fields in their Sway configuration,
I preferred to make everything optional.

I first tried to use (open-pipe wmenu OPEN_BOTH). However, I needed
to close the port to wmenu before reading its output. I do not know how
to do that with `open-pipe'.

Not sure, because program-file calls guile with --no-auto-compile.
Maybe someone else has an opinion. Also it does not really matter.

I agree to better keep the sway-bar record simple. Maybe a more
complete sway-bar should be the default value for bar rather than
optional, because it is what upstream does, although then I would
disagree with Hilton (?) and actually I prefer no bar.

In vain I tried rewriting code to use open-pipe* until I looked at the
source <https://codeberg.org/adnano/wmenu/src/tag/0.1.9/wmenu.c>:
> static void read_items(struct menu *menu) {

Well, I guess the port must be closed or wmenu does not leave the while
loop. No other way. But perhaps use pipeline from (ice-9 popen), which
is public, unlike open-process.

Hello Florian,
Please find below the v8 of the patch.
Main changes since the v7 and our last emails :
• I no longer call make-string once per line,
• I serialize the tap field of input (I forgot it before),
• I have added the resize mode of Sway in the default modes,
• I have swapped the sections "default values" and "definition of
configuration records" in sway.scm so that I could define
%sway-default-modes,
• I have proof-read the code and documentation,
• I have re-tested the code on example configurations (and have
hopefully caught all remaining small bugs/oversight).
> Please excuse the long delay.
No worries; it has only been two days :).

As suggested, I now use `pipeline'. The menu script also makes sure that
the output of wmenu is not null before trying to execute it.

+displayed on the status area of the bar.
+
+Below are a few examples using:
+@itemize
+@item
+a string: @code{"while date +'%Y-%m-%d %X'; do sleep 1; done"},
+@item
+a G-exp:
+@lisp
+#~(string-append "while "
+ #$coreutils "/bin/date"

+corresponding to left, right and scroll click respectively. For
+example, with @code{(mouse-bindings `((,%ev-code-mouse-left . "exec
+$term")))}, left clicks in the status bar open the terminal (assuming
+that the variable @code{$term} is bound to a terminal).
+@end table
+@end deftp
+
+@deftp {Data Type} sway-mode
+Describes a Sway mode (see@ @cite{sway(5)}). For example, the following

+@subsection Sway window manager
+
+@cindex sway, Home Service
+@cindex sway, configuration
+The @code{(gnu home services sway)} module provides
+@code{home-sway-service-type}, a home service to configure the
+@uref{https://github.com/swaywm/sway,Sway window manager for Wayland} in
+a declarative way.
+
+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-sway-service-type
+ (sway-configuration
+ (gestures
+ '((swipe:3:down . "move to scratchpad")
+ (swipe:3:up . "scratchpad show")))
+ (outputs
+ (list (sway-output
+ (identifier '*)
+ (bg (file-append sway
+ "\
+/share/backgrounds/sway/Sway_Wallpaper_Blue_1920x1080.png")))))))
+@end lisp
+
+The above example describes a Sway configuration in which
+@itemize
+@item
+all monitors use a particular wallpaper whose @file{.png} is provided by
+the @code{sway} package;
+@item
+swiping down (resp.@: up) with three fingers moves the active window to
+the scratchpad (resp.@: shows/hides the scratchpad).
+@end itemize
+
+@quotation Note
+This home service only sets up the configuration file and profile
+packages for Sway. It does @emph{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 @emph{optional} @code{sway-configuration}
+field of @code{greetd-wlgreet-sway-session}.
+@end quotation
+
+@deffn {Procedure} sway-configuration->file config
+This function takes a @code{sway-configuration} record (defined below),
+and returns a file-like object representing the serialized
+configuration.
+@end deffn
+
+@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
+@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 either strings, G-expressions or file-append objects
+(@pxref{G-Expressions}).
+
+Example:
+@lisp
+(variables `((mod . "Mod4") ; string
+ (term ; file-append
+ . ,(file-append foot "/bin/foot"))
+ (term ; G-expression
+ . ,#~(string-append #$foot "/bin/foot"))))
+@end lisp
+
+@item @code{keybindings} (default: @code{%sway-default-keybindings})
+This field describes keybindings for the @emph{default} mode. The value
+is an association list: keys are symbols and values are either strings
+or G-expressions.
+
+The following snippet launches the terminal when pressing @kbd{$mod+t}
+and @kbd{$mod+Shift+t} (assuming that a variable @code{$term} is
+defined):
+@lisp
+`(($mod+t . ,#~(string-append "exec " #$foot "/bin/foot"))
+ ($mod+Shift+t . "exec $term"))
+@end lisp
+
+@item @code{gestures} (default: @code{%sway-default-gestures})
+Similar to the previous field, but for finger-gestures.
+
+The following snippet allows to navigate through workspaces by swiping
+right and left with three fingers:
+@lisp
+'((swipe:3:right . "workspace next_on_output")
+ (swipe:3:left . "workspace prev_on_output"))
+@end lisp
+
+@item @code{packages} (default: @code{%sway-default-packages})
+This field describes a list of packages to add to the user profile. At
+the moment, the default value only adds @code{sway} to the profile.
+
+@item @code{inputs} (default: @code{'()})
+List of @code{sway-input} configuration records (described below).
+
+@item @code{outputs} (default: @code{'()})

+bar.
+
+@item @code{modes} (default: @code{'()})
+Optional list of @code{sway-mode} records (described below) to add modes
+to the Sway configuration (@i{e.g.}@: the ``resize'' mode of the default
+Sway configuration).
+
+@item @code{startup+reload-programs} (default: @code{'()})
+Programs to execute at startup time @emph{and} after every configuration
+reload. The value of this field is a list of strings, G-expressions or
+file-append objects (@pxref{G-Expressions}).
+
+@item @code{startup-programs} (default: @code{%sway-default-execs})
+Programs to execute at startup time. As above, values of this field are
+a list of strings, G-expressions or file-append objects.
+
+The default value, @code{%sway-default-execs}, executes @code{swayidle}
+in order to lock the screen after 5@ minutes of inactivity (displaying a
+background distributed with Sway) and turn the screen off after 10@
+minutes of inactivity.
+
+@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)}). 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")
+ (layout
+ (keyboard-layout "fr" #:options '("ctrl:nocaps"))))
+@end lisp
+
+Available fields for @code{sway-input} configuration records are:
+
+@table @asis
+@item @code{identifier} (default: @code{'*})
+Identifier of the input. The field accepts symbols and strings. If the
+@code{identifier} is a symbol, it is inserted as is; if it is a string,
+it will be quoted in the configuration file.
+
+
+@item @code{layout} (optional @code{<keyboard-layout>} record)
+Keyboard specific option. Field specifying the layout (possibly with
+options) to use for the input. The value must be a
+@code{<keyboard-layout>} record (@pxref{Keyboard Layout}).
+

+@code{keyboard-layout} procedure.
+@end quotation
+
+
+@item @code{disable-while-typing} (optional boolean)
+If @code{#t} (resp.@: @code{#f}) enables (resp.@: disables) the
+``disable while typing'' option for this input.
+
+@item @code{disable-while-trackpointing} (optional boolean)

+whose elements can be either strings or G-expressions.
+@end table
+@end deftp
+
+@deftp {Data Type} sway-output

+
+Below are a few examples using:
+@itemize
+@item
+a string: @code{"while date +'%Y-%m-%d %X'; do sleep 1; done"},
+@item
+a G-exp:
+@lisp
+#~(string-append "while "
