# SolidCraft AppImage entry point (packaging/linux/AppRun; installed by package.sh).
|
|
# Adapted from PhotoCraft's AppRun (storytold/photocraft, Apache-2.0; see ATTRIBUTION.md).
|
|
#
|
|
# On Wayland the compositor resolves a window's dock icon by taking the window's
|
|
# app_id (ai.storyteller.solidcraft) and looking up an installed .desktop file.
|
|
# An AppImage installs nothing, so every AppImage run would otherwise show the
|
|
# generic "Wayland" icon. Best-effort desktop integration: on first run
|
|
# (and whenever the AppImage's path changes) install the .desktop entry and the
|
|
# hicolor icons into $XDG_DATA_HOME, then launch. Every failure here must leave
|
|
# the launch untouched. Opt out with SOLIDCRAFT_NO_DESKTOP_INTEGRATION=1 (the pre-rename
|
|
# SOLVECRAFT_NO_DESKTOP_INTEGRATION still works: compatibility shim, docs/compatibility.md),
|
|
# or for good with an empty file $XDG_DATA_HOME/solidcraft/no-desktop-integration. Nothing is
|
|
# installed either when appimaged (go-appimage) already made an entry for this AppImage, or when
|
|
# a launcher that manages AppImages (Gear Lever, AppImageLauncher) started it: it sets
|
|
# DESKTOPINTEGRATION and owns the menu entry.
