Fish shell + WSL2 + gnome-keyring / secret-tool

config.fish

#
# This fish config sets up a working `gnome-keyring` on WSL2.
# I imagine it will work with WSL1 as well, perhaps after adjusting the `DISPLAY` value.
#
# Based off this bash script: https://askubuntu.com/questions/815327/running-gnome-keyring-on-wsl-windows-subsystem-for-linux
# Tested and working with `aws-vault` and `jetbrains-toolbox`.
#

# Be sure your x server is running!!!
set -x DISPLAY (cat /etc/resolv.conf | grep nameserver | awk '{print $2}'):0

pgrep dbus-daemon > /dev/null

if test $status -eq 1
  dbus-launch --sh-syntax | read --line bus_address ignored bus_pid bus_windowid

  set -Ux DBUS_SESSION_BUS_ADDRESS (string match -r "'(.*)'" $bus_address)[2]
  set -Ux DBUS_SESSION_BUS_ID (string match -r "=(.*);" $bus_pid)[2]
  set -Ux DBUS_SESSION_BUS_WINDOWID (string match -r "=(.*);" $bus_windowid)[2]
end

# pgrep limited to 15 chars, so truncate `daemon`
pgrep gnome-keyring-d > /dev/null

if test $status -eq 1
  gnome-keyring-daemon | read --line gnome_keyring_control ssh_auth_sock

  set -Ux GNOME_KEYRING_CONTROL (string split -m 1 = $gnome_keyring_control)[2]
  set -Ux SSH_AUTH_SOCK (string split -m 1 = $ssh_auth_sock)[2]
end

I start Sway directly from the console with no display manager. I start Gnome Keyring Daemon with a systemd user unit that ships with the Arch Linux gnome-keyring package.

To set the environment variables, I have this in ~/.config/fish/config.d/999-sway.fish:

# If running from tty1 and a graphical session has not already been started, start Sway
set TTY1 (tty)
if status --is-login && test "$TTY1" = "/dev/tty1"  && test -z $WAYLAND_DISPLAY

  # gnome-keyring prints bash-style env vars when starting, namely SSH_AUTH_SOCK
  # fenv will use bash to eval that output and then convert the "foreign environment"
  # a native Fish environment
  fenv "eval $(gnome-keyring-daemon --start)"
  set --global --export DESKTOP_SESSION "sway"
  set --global --export TERMINAL "foot"
  set --global --export _JAVA_AWT_WM_NONREPARENTING 1
  set --global --export QT_AUTO_SCREEN_SCALE_FACTOR 1
  set --global --export QT_QPA_PLATFORM wayland
  set --global --export QT_WAYLAND_DISABLE_WINDOWDECORATION 1
  set --global --export MOZ_ENABLE_WAYLAND 1
  set --global --export MOZ_WEBRENDER 1
  set --global --export MOZ_ACCELERATED 1
  set --global --export BEMENU_BACKEND wayland
  set --global --export GTK_THEME "Adwaita:dark"

  # DON'T use exec so that environment variable inheritance works correctly.
  # We name this script with the 999 prefix because the sway execution blocks and no other scripts
  # will run until after it exits.
  /sbin/sway
end
