# Map forge information to rpm metadata. This macro will compute default spec
# variable values.
#
# The following spec variables SHOULD be set before calling the macro:
#
#   forgeurl  the project url on the forge, strongly recommended;
#   Version   if applicable, set it with Version: <version>
#   tag       if applicable
#   commit    if applicable
#   date      if applicable (to override the mtime of the Source archive)
#
#  Use -z for multiple calls to the macro
#
# The macro will attempt to compute and set the following variables if they are
# not already set by the packager:
#
#   forgesource    an URL that can be used as SourceX: value
#   forgesetupargs the correct arguments to pass to %setup for this source
#                  used by %forgesetup and %forgeautosetup
#   archivename    the source archive filename, without extentions
#   archiveext     the source archive filename extensions, without leading dot
#   archiveurl     the url that can be used to download the source archive,
#                  without renaming
#   topdir         the source archive top directory (can be empty)
#   extractdir     the source directory created inside %{_builddir} after using
#                  %%forgesetup, %forgeautosetup or %{forgesetupargs}
#   repo           the repository name
#   owner          the repository owner (if used by another computed variable)
#   shortcommit    the commit hash clamping used by the forge, if any
#   scm            the scm type, when packaging code snapshots: commits or tags
#   distprefix     the prefix that needs adding to dist to trace non-release packaging
#
# Most of the computed variables are both overridable and optional.
#
# Optional parameters:
#   -a          process all sources in one go, instead of using separate -z calls
#   -z <number> suffix all the read and written variable names with <number>
#               for example read     forgeurl<number>, version<number>…
#                       and generate forgesetupargs<number>, archiveurl<number>…
#               The macro assumes that null or nil suffix is used for the primary
#               package source.
#   -s  Silently ignore problems in forgeurl, use it if it can be parsed,
#       ignore it otherwise.
#   -v  Be verbose and print every spec variable the macro sets.
#   -i  Print some info about the state of spec variables the macro may use or
#       set at the end of the processing.
