Rails dev tools

This is a collection of utilities used for Rails internal development. They aren’t used by Rails apps directly.

  • console drops you in irb and loads local Rails repos

  • profile profiles Kernel#require to help reduce startup time

  • railspect provides commands to run internal linters

  • line_statistics provides CodeTools module and LineStatistics class to count lines

  • test is loaded by every major component of Rails to simplify testing, for example: cd ./actioncable; bin/test ./path/to/actioncable_test_with_line_number.rb:5
