Creates AppImages from AppDirs. For use with linuxdeploy.

As this software is concepted as a plugin for linuxdeploy, it is recommended to use it as such.

When calling linuxdeploy, just add --output appimage to enable the plugin. After completing the bundling process and running e.g., input plugins, linuxdeploy will then call the AppImage plugin to create an AppImage from the AppDir.

For more information, see the official AppImage packaging guide.

Like all linuxdeploy plugins, linuxdeploy-plugin-appimage is a standalone tool and can be used without linuxdeploy.

Please see the --help test for more information.

The official linuxdeploy AppImage ships with a fairly recent version of the plugin. You can at any time still download the AppImage from the release page, and put it into the same directory as linuxdeploy. Then, linuxdeploy will use the AppImage instead of the bundled version.

For more information on how linuxdeploy's plugin system works, please refer to the documentation.

linuxdeploy-plugin-appimage can be configured using environment variables.

• UPDATE_INFORMATION="...": embed update information in the AppImage, and generate corresponding .zsync file
• SIGN=1: set this variable to any value to enable signing of the AppImage
• SIGN_KEY=key_id: GPG Key ID to use for signing. This environment variable is only used if SIGN is set.
• VERBOSE=1: set this variable to any value to enable verbose output
• OUTPUT=filename: change filename of resulting AppImage
• NO_APPSTREAM=1: skip checking AppStream metadata for issues
