NAME

       appstream-generator - Generate AppStream metadata from distribution repositories

SYNOPSIS

       appstream-generator [COMMAND]

DESCRIPTION

       This manual page documents briefly the appstream-generator command.

       appstream-generator generates AppStream metadata from the repositories of a software
       distribution. It currently supports the following repository formats / distributions:
       Debian, Ubuntu, Arch Linux, RPM-MD (Fedora, Mageia).

       The generator will produce AppStream collection metadata files in the AppStream YAML or
       XML format to be shipped to users, as well as a detailed HTML report about found
       components and HTML and JSON reports on issues detected with the scanned metadata. It
       reads .desktop files as well as metainfo files, renders fonts, scales images, caches
       screenshots etc. to produce high-quality metadata for AppStream based software centers to
       consume. Usually, appstream-generator is integrated with the existing software build &
       delivery workflow of a distribution.

       The appstream-generator tool is based on the libappstream library for metadata conversion
       and analysis. If you just want to embed AppStream metadata processing into another tool,
       using libappstream is likely a better choice. The generator tool does some heavy lifting
       like rendering fonts and scaling images, which might not be necessary for simple cases.

       To use appstream-generator, a asgen-config.json file is required. Its format is described
       in detail in the asgen-config.json documentation[1].

       For more information about the AppStream project and the other components which are part
       of it, take a look at the AppStream pages at Freedesktop.org[2].

OPTIONS

       process SUITE
           Process new metadata for the given distribution suite.

       cleanup
           Cleanup old/expired metadata and media files from the cache and directories.

       remove-found SUITE
           Drop all valid processed metadata and hints from the selected suite.

       forget PKID
           Drop all information we have about this (partial) package-id.

           A package-id consists of a name/version/arch triplet. For this command, the version
           and architecture can be omitted.

       info PKID
           Show information associated with this (full) package-id.

           A package-id consists of a name/version/arch triplet.

       -w|--workspace
           Define the workspace location.

           If this flag is omitted, the current directory is assumed as the workspace location.

       --force
           Enforce the command.

       --verbose
           Show extra debugging information.

       --version
           Display the version number of appstream-generator.
