- ○○がしたい！！！！
- どんなライブラリがあるか調べよう！
- gem search ○○ --remote する
- 名前だけたくさん出てくる…
- 調べるのめんどくさい…………
というわけで適当にやっつけで書いてみました。
require "yaml" require "rubygems/specification" search_word = ARGV[0] output = ` gem search #{search_word} --remote ` gem_names = output.split("\n").map{|line| /^(.+) \(.+\)$/ =~ line $1 } gem_names.each{|gem_name| yaml = ` gem specification #{gem_name} --remote` info = YAML.load(yaml) puts "** [%s:title=%s (%s)]\n\n" % [info.homepage, info.name, info.version] puts "- date: %s" % info.date puts "- licenses: %s" % [ info.licenses.empty? ? "(no data)" : info.licenses.join(", ") ] puts "- dependencies: %s" % info.dependencies.map{|dep| dep.name }.join(", ") # puts "requirements: %s" % info.requirements.join(", ") puts "- summary: %s" % info.summary puts "description: " puts ">>" puts info.description puts "<<\n\n" sleep 1 }
gem search に与えるキーワードを与えて実行
ruby list_gem_info.rb {キーワード}
すると、次のように出力されます。以下は「diff」で検索してみた場合。
はてな記法です。
** [http://github.com/agrussellknives/activerecord-diff:title=activerecord-diff (0.0.2)] - date: 2011-10-13 14:00:00 +0900 - licenses: (no data) - dependencies: activerecord, activesupport, bundler, rake, sqlite3-ruby - summary: Gemify Simple diff for ActiveRecord objects. description: >> Simple diff for ActiveRecord << ** [http://moonwolf.com/:title=algorithm-diff (0.1)] - date: 2004-10-25 13:00:00 +09:00 - licenses: (no data) - dependencies: - summary: Computes the differences between two arrays of elements description: >> << ** [http://github.com/radamant/analdiffist:title=analdiffist (0.4.0)] - date: 2011-07-06 16:00:00 +0900 - licenses: (no data) - dependencies: reek, flog, rspec, bundler, jeweler, autotest - summary: A professional twice over: an analyst and a diffist. description: >> A tool for comparing the complexity and code smells between two git revisions << （以下略）
※ちなみに gem search のオプションで --details というのもあります（でも動いてくれませんでした…）。
※summary だけでいいなら http://rubygems.org/ で検索するのも良いかも。
