NAME

       modulemd-validator - validate modulemd documents

SYNOPSIS

       modulemd-validator [--quiet|--verbose|--debug] FILE...
       modulemd-validator [--quiet|--verbose|--debug] --type=TYPE FILE
       modulemd-validator {--version|--help}

DESCRIPTION

       This  tool  validates  modulemd  documents specified with the positional arguments using a
       libmodulemd parser.

       Without a --type option, all document types which can be found in a YUM repository will be
       recognized. In this case each FILE can contain multiple modulemd documents.

       Otherwise,  exactly one FILE containing exactly one modulemd document must be provided and
       the document will be validated against the given TYPE.

OPTIONS

       --type=TYPE
              Constrain a document type. The recognized types are:

              modulemd-v1
                     An obsolete format used for building and installing modules.

              modulemd-v2
                     A deprecated format for building modules and a contemporary format for built
                     modules which can be placed into a YUM repository and installed by a package
                     manager.

              modulemd-defaults-v1
                     A format for defining default streams and  default  profiles  of  a  module.
                     Found in YUM repositories.

              modulemd-obsoletes-v1
                     A  format for defining streams which reach or will reach its end of life. It
                     can also recommend a new stream which obsoleted the old one.  Found  in  YUM
                     repositories.

              modulemd-packager-v2
                     An obsolete format for building modules.

              modulemd-packager-v3
                     A contemporary format for building modules.

              modulemd-translations-v1
                     A  contemporary format for delivering localized human-oriented texts (e.g. a
                     description  or  a  summary)  associated  with  a  module.  Found   in   YUM
                     repositories.

              Only  single-document  files  are supported.  For compatibility, if this options is
              not provided, any document type loadable into a modulemd index (i.e. those intended
              for YUM repositories) is acceptable.

       --debug
              Output debugging messages.

       -q, --quiet
              Print no output.

       -v, --verbose
              Be verbose.

       -h, --help
              Print a usage text and then exit.

       -V, --version
              Print a version number and then exit.

EXIT CODE

       If  the  supplied  documents  are valid (and satisfy the --type constrain), zero exit code
       will be returned.  Otherwise a non-zero code will be emitted.
