The store package will own meshterm.desktop and meshterm.png. The entry that launcher-entry.sh makes is now meshterm-dev.desktop with a negative of the logo, so that the two look different and can be installed together. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

# launcher-entry -- put MeshTerm on the app launcher of the Cardputer Zero, from a checkout.
|
|
#
|
|
# Usage: scripts/cardputer-zero/launcher-entry.sh [install|remove]
|
|
#
|
|
# The stock launcher (APPLaunch) lists the entries that it finds in
|
|
# /usr/share/APPLaunch/applications. An entry with Terminal=false gets the display and the
|
|
# keyboard for itself. The launcher names them in APPLAUNCH_LINUX_FBDEV_DEVICE and
|
|
# APPLAUNCH_LINUX_KEYBOARD_DEVICE. This is how `python -m meshterm.emulator` knows that it
|
|
# must draw on the display and not open a window. If the user holds Esc for three seconds,
|
|
# the app still ends. The launcher sends SIGTERM, and MeshTerm treats it as a quit.
|
|
#
|
|
# This is the entry for developers. Run it from a source checkout that has its venv at
|
|
# .venv (refer to docs/devices/cardputer-zero.md). It writes into /usr/share, so it asks
|
|
# sudo for the two files and for nothing else. Then it restarts the launcher, so that the
|
|
# icon appears. `remove` takes it out again.
|
|
#
|
|
# The entry has its own file names and a negative icon (meshterm-dev.png). Thus it is not
|
|
# the same as the entry of the package from the store (build-deb.sh), and the two can be
|
|
# installed together. The package owns meshterm.desktop and meshterm.png, and this script
|
|
# never touches them.
