# Recommended VMware development session entry point.

# Sets compositor-side development environment (cursor theme, software
# cursors if needed) and starts Sway with the Nebula development config.
# Sway then autostarts nebula-shell via scripts/run-nebula-vm.sh.
#
# Usage:
#   ./compositor/sway/dev/run-sway-vm.sh
#
# Equivalent:
#   export XCURSOR_THEME=Adwaita XCURSOR_SIZE=24
#   sway -c compositor/sway/nebula-sway.conf
#
# Skip shell autostart:
#   NEBULA_SHELL_AUTOSTART=0 ./compositor/sway/dev/run-sway-vm.sh
