# A directory for rpm macros
%rpmmacrodir /usr/lib/rpm/macros.d

# A directory for appdata metainfo.  This has changed between releases so a
# macro is useful.

# A directory for SWID tag files describing the installation
%_swidtagdir %{_prefix}/lib/swidtag/fedoraproject.org

# A helper to apply the fedora.wordwrap filter to the content of an rpm
# variable, and print the result. Optional parameter:
#  – -v <variable_name> (default value: _description)
# Putting multiple lines of UTF-8 text inside a variable is usually
# accomplished with a %%{expand: some_text}.
%wordwrap(v:) %{lua:
local   fedora = require "fedora.common"
local variable = "%{" .. rpm.expand("%{-v*}%{!-v:_description}") .. "}"
print(fedora.wordwrap(variable))

# A wrapper around Name: and %package that abstracts their quirks from
# packagers and macros. Its behavior is controled by the %{source_name}
# global variable:
# – when %{source_name} is not set, the first call to %new_package will
#   create a Name: block and set %{source_name} to the %{name} of this
#   block.
# – when %{source_name} is set:
#   – a call to %new_package with no arguments creates:
#     Name: %{source_name}
#   – otherwise, a call to %new_package creates the corresponding:
#     %package…
#     line, unless the resulting %{name} matches %{source_name}. In that
#     case it creates
#     Name: %{source_name}
#     as before.
# Arguments:
# – -n and %1 like %package
# – -v to print the variables %new_package sets directly.
# The intended use-case it to simplify coordination between macros that
# create subpackages, make it easy for packagers to declare which of the
# macro-created packages owns the SRPM, and make %{source_name} available
# within spec files and not just as a dnf synthetic variable.
# Unlike %{name} %{source_name} matches the SRPM name regardless of its
# location within the spec file.
