Gemfileに記載してあるgemの説明を一覧で表示する #fjordbootcamp
追記: bundle info でgemの情報を表示できるので、一覧じゃなければコレで十分かも。

これを読んでいて、ふと「gemspecから説明を抜き出して、一覧で表示できると便利そう」と思いついたので、試しに実装してみた。
コード
#!/usr/bin/env ruby # frozen_string_literal: true require 'bundler' lockfile = Bundler.default_lockfile.read parser = Bundler::LockfileParser.new(lockfile) spec_per_name = parser.specs.group_by(&:name).transform_values(&:first) parser.dependencies.keys.each do |name| spec = spec_per_name[name] if spec path = "#{Bundler.specs_path}/#{name}-#{spec.version}.gemspec" gemspec = Gem::Specification.load(path) end puts "#{name}: #{gemspec&.summary}" end
