# Unfortunately, the circular dependency is intentional; the clib extension
# packaged here imports from ruamel.yaml, which in turn uses the extension for
# performance.
BuildRequires:  python3-ruamel-yaml
Requires:       python3-ruamel-yaml

# Bundled sources from libyaml are:
#   - config.h yaml.h yaml_private.h
#   - api.c dumper.c emitter.c loader.c parser.c reader.c scanner.c writer.c
#
# Support building with an external/system copy of libyaml?
# https://sourceforge.net/p/ruamel-yaml-clib/tickets/15/
#
# Upstream replied:
#
#   The copy is because there have been improvements where libyaml had not been
#   maintained for several years. But that is minor reason to do that, as I am
#   working on an alternative for clib.
#
# Version number from VERSION in config.h:
Provides:       bundled(libyaml) = 0.1.7
