Puts by name

Ruby

I very often do something like:
puts “some_variable.something = #{some_variable.something}”

That repetition is getting annoying.

Is there an idiomatic Ruby way to do something like
puts_v some_variable.something

Yes.

If you’re repeating it that much, you’re not writing enough tests. :slight_smile:
Using p can save you a bit of annoyance, but not much:

p :something => some_variable.something

~ j.

Given this:

some_variable = Object.new
def some_variable.something; “hello”; end

Option 1

def puts_v(str, b)
puts “#{str} = #{eval(str, b).inspect}”
end

puts_v “some_variable.something”, binding

Option 2, using a block to get the Binding

def puts_v(&blk)
str = yield
puts “#{str} = #{eval(str, blk).inspect}”
end

puts_v { “some_variable.something” }

Option 2a, looks a bit odd

puts_v {%{some_variable.something}}
