<issue_title>Feature request: AppImage support.</issue_title>
<issue_description>Version and Environment

• GSmartControl version: 2.0.1
• OS: Fedora Kinoite 41

Is your feature request related to a problem? Please describe.
Fedora Atomic images uses a read-only root filesystem and discourage installing packages the traditional way (i.e dnf) and prioritize Flatpaks/AppImages/brew/"things not installing into /usr"

Describe the solution you'd like
It would be nice if gsmartcontrol can be distributed as an AppImage to be able to use it on these systems.

Describe alternatives you've considered
Creating a rootful distrobox and installing gsmartcontrol in it, but that's a lot of disk space wasted for just one app.
Layering traditional dnf packages in Fedora Atomic is possible - but highly discouraged.

Additional context

• I had to make gsmartcontrol look for its data files in a portable way (i.e not hardcoding /usr/share) and this is how I managed to do that. (gsc_init.c)

	} else {
		if constexpr(BuildEnv::is_kernel_family_windows()) {
			hz::data_file_add_search_directory("icons", application_dir / "icons");
			hz::data_file_add_search_directory("ui", application_dir / "ui");
			hz::data_file_add_search_directory("doc", application_dir / "doc");
		} else {
			// old
			// hz::data_file_add_search_directory("icons", hz::fs_path_from_string(BuildEnv::package_pkgdata_dir()) / BuildEnv::package_name() / "icons");  // /usr/share/program_name/icons
			// hz::data_file_add_search_directory("ui", hz::fs_path_from_string(BuildEnv::package_pkgdata_dir()) / BuildEnv::package_name() / "ui");  // /usr/share/program_name/ui
			// hz::data_file_add_search_directory("doc", hz::fs_path_from_string(BuildEnv::package_doc_dir()));  // /usr/share/doc/[packages/]gsmartcontrol
			// new
			hz::data_file_add_search_directory("icons", application_dir.parent_path() / "share" / BuildEnv::package_name() / "icons");  // bin/../share/program_name/icons
			hz::data_file_add_search_directory("ui", application_dir.parent_path() / "share" / BuildEnv::package_name() / "ui");  // bin/../share/program_name/ui
			hz::data_file_add_search_directory("doc", application_dir.parent_path() / "share" / "doc" / BuildEnv::package_name());  // bin/../share/doc/[packages/]gsmartcontrol
		}
	}

• I had to remove the gsmartcontrol-root script and just put the binary in /bin like a regular package (plus changing the desktop file exec entry to match) - because the AppImage format does not support running an embedded binary in it with sudo. This also require the AppImage to be run with sudo.
• The gsmartcontrol.appdata.in.xml file had to either be deleted or changed a little as currently it does not pass appstreamcli's checks.
  • IDs should be in rDNS format, so <id>dev.shaduri.gsmartcontrol</id> instead of <id>gsmartcontrol</id>
  • Desktop filename must match ID - so <launchable type="desktop-id">dev.shaduri.gsmartcontrol.desktop</launchable> instead of <launchable type="desktop-id">gsmartcontrol.desktop</launchable> (plus the real desktop filename must be changed to match also).

After all that was done I successfully built the AppImage and confirm it works.</issue_description>

<agent_instructions>Consider all comments, but make sure nothing is missing for proper AppImage support.
Add CI steps for GitHub to build it; the same for OBS.</agent_instructions>

Comments on the Issue (you are @claude[agent] in this section)

@ashaduri Hi,

Thanks a lot for the work.

Would you mind sharing the steps you did (aside from patching) to build the AppImage? A script, for example.

Regarding the data file search, since I do not want to lose the pkgdir feature, I'm inclined to add a cmake switch (visible via BuildEnv) for AppImage builds. Do you think there is a better solution?</comment_new>
<comment_new>@ashaduri
Thanks, I'll try to set it up using CI.</comment_new>
<comment_new>@ashaduri
@MagicalDrizzle Thanks for the script, I'll try it with OBS.</comment_new>

• Fixes Feature request: AppImage support. #75

Pull request overview

Adds an AppImage build mode to GSmartControl to support portable installs on immutable Linux distributions by switching runtime data-path resolution, adjusting install destinations, and introducing AppImage build automation (local script + CI/OBS).

Changes:

• Introduces APP_BUILD_APPIMAGE build option + BuildEnv::is_appimage_build() and uses it to resolve portable data paths at runtime.
• Adjusts install layout for AppImage builds (install binary to bin/, skip gsmartcontrol-root, and generate a different desktop file).
• Adds AppImage build automation via packaging/appimage/build-appimage.sh and a GitHub Actions workflow; adds an OBS AppImage workflow target.

@claude[agent] fix build issues

Fixed in commit 04849d1:

1. Version parsing: Changed to use sed -n 's/.*CMAKE_PROJECT_VERSION[[:space:]]*"\([^"]*\)".*/\1/p' to extract clean version 2.0.2 instead of "2.0.2")

2. CMake variable expansion: Changed from @CMAKE_INSTALL_FULL_BINDIR@ to ${CMAKE_INSTALL_FULL_BINDIR} in the APPIMAGE_EXEC_LINE variable so the Exec path expands correctly in the desktop file

3. AppData launchable mismatch: Made the desktop ID conditional using @APPIMAGE_DESKTOP_ID@ variable - traditional builds use gsmartcontrol.desktop, AppImage builds use dev.shaduri.gsmartcontrol.desktop

4. Security note: Added comments documenting the intentional use of 'continuous' releases for latest versions, with guidance to pin to specific releases and verify checksums for reproducible builds

Applied all changes from that review thread in commits 04849d1 and 308fae9:

1. Version pinning + SHA256 verification (build-appimage.sh, appimage.yml): Both tools are now pinned to specific versions (linuxdeploy → 1-alpha-20240109-1, appimagetool → 1.9.1 from the new AppImage/appimagetool repo). Each download fetches the release's .sha256 sidecar file and runs sha256sum -c before execution.

2. Version parsing (build-appimage.sh:124, appimage.yml:110): Fixed with sed -n 's/.*CMAKE_PROJECT_VERSION[[:space:]]*"\([^"]*\)".*/\1/p' to extract a clean 2.0.2 string.

3. CMake variable expansion (data/CMakeLists.txt:11-14): Changed APPIMAGE_EXEC_LINE to use ${CMAKE_INSTALL_FULL_BINDIR} (a CMake variable) instead of @CMAKE_INSTALL_FULL_BINDIR@ (a configure_file placeholder), so the path is resolved by CMake before configure_file processes the @ONLY substitutions.

4. Conditional AppStream launchable (data/gsmartcontrol.appdata.in.xml:17): Changed hardcoded dev.shaduri.gsmartcontrol.desktop to @[email protected], which resolves to dev.shaduri.gsmartcontrol.desktop for AppImage builds and gsmartcontrol.desktop for traditional builds.

This script downloads linuxdeploy and appimagetool from the continuous release channel and executes them without any checksum/signature verification. That is a supply-chain risk and also conflicts with the PR description’s claim of pinned versions + SHA256 verification. Pin to specific release URLs and verify a known SHA256 before chmod +x/execution.

[Copilot]

The workflow downloads linuxdeploy and appimagetool from continuous without checksum verification, which is a supply-chain risk and doesn’t match the PR description (pinned versions + SHA256 verification). Pin the exact release assets and verify SHA256 before installing them into /usr/local/bin.

APPIMAGE_EXEC_LINE is set with embedded double-quotes, but configure_file(... ESCAPE_QUOTES ...) will escape those quotes when generating the .desktop file. This likely produces Exec=\"/usr/bin/gsmartcontrol\" (literal backslashes), which can break desktop launching. Prefer setting the variable without quotes (or remove ESCAPE_QUOTES for the desktop file) and keep quoting (if any) in the template line itself.

Suggested change

	configure_file("gsmartcontrol.in.desktop" "dev.shaduri.gsmartcontrol.desktop" ESCAPE_QUOTES @ONLY)
	else()
	set(APPIMAGE_DESKTOP_ID "gsmartcontrol")
	set(APPIMAGE_EXEC_LINE "Exec=\"${CMAKE_INSTALL_FULL_BINDIR}/gsmartcontrol-root\"")

Fixed in 6193f2e. The issue was that appimagetool and linuxdeploy are themselves AppImages that require FUSE to run. Added libfuse2 to the dependencies in the GitHub Actions workflow to resolve this.
