trying out go wrapper + cpanm
Raw
gistfile1.txt
# DockerでCPANインストール祭りを繰り返してたらいい加減cpanmとかに並列処理が欲しくなってきた。
# で、とりあえずgoでラッパーを作って、
# 1) 先にMETA.yamlを読み込み、依存関係を解析
# 2) キューに突っ込んで goroutineでそれぞれcpanmを起動してインストール
# という簡単な処理をしてみてどういう差が出るかやってみた
#
# 試すには go install github.com/lestrrat/go-cpan-maybe-faster/cli/go-cpan
# https://github.com/lestrrat/go-cpan-maybe-faster
