File generate_buildrequires.sh of Package ruby-common
#!/bin/sh # # In the current package's specfile, updates a block delimited # by "# BEGIN" / "# END" lines to contain BuildRequires: lines # for each rubygem rpm (or rpm matching a given pattern) which # has been built by the project. # # This gives us project-build-time dependency checking without the # performance impact that specifying BuildRequires lines within # each gem would cause. For more information, see: # # http://en.opensuse.org/openSUSE:Packaging_Ruby#Compensating_for_lack_of_BuildRequires # # Usage: # ------ # # 1. Ensure you have an "all-rubygems-good" package or similar # in your project. If in doubt, copy the one from # devel:languages:ruby:extensions. # # 2. cd to a working copy # # If you're feeling lazy, you are probably fine skipping the next two # steps. # # 3. Run this script with the -l option and make sure you understand # any differences between each repository/arch combination in the # numbers of matching gems found. # # 4. If you don't, run with -l REPO ARCH to compare individual lists # of matching gems. # # 5. If you want a BuildRequires: list of matching gems from *all* # repo/arch combinations, run again with no arguments. # # OR # # If you want a BuildRequires: list of matching gems from a specific # repo/arch combinations, run again with REPO ARCH as arguments. # # 6. osc diff to review the changes to the spec file, then osc commit. me=`basename $0` DEFAULT_PATTERN="rubygem-" main () { parse_opts "$@" if [ -z "$project" ]; then project=$( osc info | sed -ne '/^Project name: / { s///; p }' ) if [ -z "$project" ]; then echo "Couldn't establish build service project name." >&2 echo "Are you inside a package working directory?" >&2 exit 1 fi fi echo "Project: $project" case "$project" in home:*:branches:*) cat <<EOF >&2 WARNING: you are running this in a branch.
