# Deploy peek-mobile to a postmarketOS / Phosh device.
#
# Usage: ./install.sh user@host
#
# Prerequisite: build the binary first with apps/mobile/build-linux.sh.
# Prerequisite: target device has webkit2gtk-4.1 installed (`sudo apk add
# webkit2gtk-4.1`) and SSH key auth set up.
#
# What it deploys:
#   ~/peek-save                                     binary
#   ~/peek-launch.sh                                env wrapper
#   ~/.local/share/applications/peek-save.desktop   drawer entry
#   ~/.config/autostart/peek-save.desktop           autostart (login)
#   ~/.local/share/icons/hicolor/{128,256}x*/apps/peek.png   round icons
#
# The .desktop filename matches the running window's Wayland app_id
# ("peek-save"), which is what Phosh needs to associate the running
# window with the launcher entry (icon, name).
