Date: Wed, 2 Oct 2024 00:12:58 +0200
* gnu/home/services/sway.scm: New file. (home-sway-service-type): New variable. (sway-configuration->file): New procedure. (sway-configuration): New configuration record. (sway-bar): New configuration record. (sway-output): New configuration record. (sway-input): New configuration record. (point): New configuration record. (sway-color): New configuration record. (sway-border-color): New configuration record. (sway-mode): New configuration record. (flatten): New procedure. * gnu/local.mk: Add gnu/home/services/sway.scm. * doc/guix.texi (Sway window manager): New node to document the above changes. --- 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 Best regards, doc/guix.texi | 394 ++++++++++++++++++ gnu/home/services/sway.scm | 794 +++++++++++++++++++++++++++++++++++++ gnu/local.mk | 1 + 3 files changed, 1189 insertions(+) create mode 100644 gnu/home/services/sway.scm diff --git a/doc/guix.texi b/doc/guix.texi index 52e36e4354..f5911a19c6 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -130,6 +130,7 @@ Copyright @copyright{} 2024 Richard Sent@* Copyright @copyright{} 2024 Dariqq@* Copyright @copyright{} 2024 Denis 'GNUtoo' Carikli@* Copyright @copyright{} 2024 Fabio Natali@* +Copyright @copyright{} 2024 Arnaud Daby-Seesaram@* Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or @@ -460,6 +461,7 @@ Home Services * Mail: Mail Home Services.
