Quickly open the source file of a Class, Module, or Method in your favourite editor, from Ruby.
First make sure your EDITOR environment variable is set (How do I find and set my $EDITOR environment variable?).
Then use as you wish
# probably in a console, though doesn't have to be require 'open_source' # not needed if it's in your Gemfile, and this environment is loaded by bundler open_source "User" # opens file where User class is defined oso User # same as above; use the aliases for ease of use! oso Authenticable # opens file where Authenticable module is defined oso :log # opens file where "log" method is defined oso "log" # same oso method :log # you get the idea oso Rails.method(:application) oso User.instance_method(:name)
Line numbers are supported too, currently for Vi and VsCode.
Add this line to your application's Gemfile:
gem 'open_source_location', require: "open_source"
And then execute:
$ bundle install
Or install it yourself as:
$ gem install open_source_location
Just make sure you then
require 'open_source' where you need it.
