Peek::Rblineprof

Peek into how much time each line of your Rails application takes throughout a request.

Things this peek view provides:

  • Total time it takes to render individual lines within your codebase
  • Total network time spent waiting per line

You can also drill down to only certain parts of your codebase like:

  • app, everything within Rails.root/(app|lib)
  • views, everything within Rails.root/app/view
  • gems, everything within Rails.root/vendor/gems
  • all, everything within Rails.root
  • stdlib

Installation

Add this line to your application's Gemfile:

gem 'peek-rblineprof'

And then execute:

$ bundle

Or install it yourself as:

$ gem install peek-rblineprof

Usage

Add the following to your config/initializers/peek.rb:

Peek.into Peek::Views::Rblineprof

You'll then need to add the following CSS and CoffeeScript:

CSS:

//= require peek
//= require peek/views/rblineprof

CoffeeScript:

#= require peek
#= require peek/views/rblineprof

Integration with pygments.rb

By default peek-rblineprof renders the code of each file in plain text with no syntax highlighting for performance reasons. If you'd like to have your code highlighted as it does on GitHub.com, just include the pygments.rb gem:

gem 'pygments.rb', :require => false

peek-rblineprof will now highlight each file for you, but there's one more thing...

To use the default theme that peek-rblineprof provides just add the following to your peek specific or application stylesheet:

//= require peek/views/rblineprof/pygments

That's it! Now your code will look
