intent

Do only what you intend.

Usage

You can use Intent to create a cross section of a large codebase.

For example, run the following code.

Intent.slice do
  fire_the_missiles
end

You will see Intent spring into action:

[slice] Running...
[slice] Analyzing trace...
[slice] Slicing files...
  -> app/models/core/country.rb
  -> app/models/core/city.rb  
  -> lib/missile_guidance.rb
  -> lib/launch_codes.rb
[slice] Done. :)

It will trace the execution of fire_the_missiles and create a new directory within the project called .slice. This folder will contain only the methods that were executed during the block, possibly reducing the breadth of a large codebase down to just a few methods that need to be considered for inspection.
