dp

Tired of writing long debug prints like this?

puts "name=#{name}, @age=#{@age}, team=#{team.inspect}"

or perhaps you're writing terse debug prints like this

p name, @age, team

but have a hard time reading the, since you don't see which is what in the output? In that case, d.p can help.

This example:

require 'dp'

def some_method
  name = 'Niclas'
  @age = 38
  team = ['Niclas', 'Johan', 'Hans']

  # Call d.p with a comma-separated string of expressions you'd like to see printed.
  d.p "name, @age, team"
end

will give this output:

name="Niclas", @age=38, team=["Niclas", "Johan", "Hans"]

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

  • Send me a pull request. Bonus points for topic branches.
