Railsのログファイルを検索する
やっつけ感がそこはかとないのだけど: select_rails_log.rb
使い方はこんな感じ。
コントローラとアクションを指定して抽出する。(アクションは省略可、カンマ区切りで複数指定可)
$ ruby ~/src/select_rails_log.rb log/production.log -a 'ItemsController#new'
time: 2018-02-08 15:55:48 +0900 .. 2018-02-08 15:55:48 +0900
id: 7592812d-b11f-46d0-9567-b4f287f37079

Rendered items/new.html.erb within layouts/application (11.2ms)
Completed 200 OK in 19ms (Views: 11.7ms | ActiveRecord: 0.2ms)
日時を指定して抽出する。(..で期間を指定するか,で前後n秒を指定する)
$ ruby ~/src/select_rails_log.rb log/production.log -t '2/8 15:55:48,3'

params(inspectされた文字列; eval注意)に対する正規表現マッチで抽出する。
$ ruby ~/src/select_rails_log.rb log/production.log -p '"id"=>"\d"'
time: 2018-02-08 15:55:58 +0900 .. 2018-02-08 15:55:58 +0900

抽出した中のParametersをevalしてppして表示する。(手抜き)
