Calleree helps to analyze Ruby's caller-callee relationships. Note that this tool consumes memory and introduces additional overhead because of dynamic analysis.

Add this line to your application's Gemfile:

gem 'calleree'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install calleree

     1
     2  require 'calleree'
     3
     4  def foo
     5    :foo
     6  end
     7
     8  def bar
     9    foo
    10  end
    11
    12  Calleree.start
    13
    14  foo
    15
    16  pp Calleree.result

And this program shows:

[[["test.rb", 14], ["test.rb", 5], 1],
 [["test.rb", 16], ["/mnt/c/ko1/src/rb/calleree/lib/calleree.rb", 24], 1]]

The Calleree.result method returns an array of arrays which contains [[caller_path, caller_line], [callee_path, callee_line], called_caount].

In this case, foo at ["test.rb", 5] is called at ["test.rb", 14] only once.

• You can stop the analisys with Calleree.stop. Calleree.start will continue the analysis.
• You can use block with Calleree.start do ... end.
• You can clear the result if Calleree.result(clear: true) is passed.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
