SourceRoute

Wrapper of TracePoint

Dependency

ruby 2

Installation

Add this line to your application's Gemfile:

gem 'source_route'

And then execute:

$ bundle

Or install it yourself as:

$ gem install source_route

Usage

In irb or pry

SourceRoute.trace output_format: :console, event: :c_call do
  'abc'.upcase
end

In rails console

SourceRoute.trace defined_class: :ActiveRecord, output_format: :html do
  User.new
end

It will generate a html file, open it and you can get the trace of User.new

The intereting part is when you run the above command again(in same console), you will get a different trace file.

In your ruby application

SourceRoute.enable :wanted_method_name
.... # here is your code
....
# may be code this in another file
SourceRoute.build_html_output

Same as the previous example, you will get a html file showing the code trace.

In a small application, you may try this

SourceRoute.enable do
  defined_class :wanted_class_name
  output_format :console
end
.... # here is your code

It will output the trace when you run the application.

Why

I always wanna upgrade my ruby(rails) skills. But everytime when I look for workaround from stack overflow I feel frustration.

To get solution or workaround from google or stack overflow is suitable when I'm a ruby starter or deadline is urgent. But it's not really helpful for my skills.

The way how I solve problem define my skills border and depth. So if I slove problems by search google and stack overflow with workarounds, I mostly just increase my experiences on ruby(rails). But if I solve problems directly, in most case, I can say my skill border extends.

That's why I create this gem. To solve problems directly, I need to know what happened in call or return traces. Fortunately ruby 2.0 introduce a new feature TracePoint to easily trace inner event. But it's not easily to be used as daily tool. This gem tries to make tracing more readable and easily in our daily work.

Finally, I expect my working style can change from searching workaround from internet to reading code trace(then more easily check source) directly. I hope it can help you too.

Test

$ bundle install
$ rake
