Feature #4095: C1 Coverage

• Status: Closed

=begin
The built-in coverage in Ruby 1.9 is great, but it only offers line-by-line coverage.

It would be better if we could determine which parts of each line have been run e.g:

File 'coverage_example.rb'

true ? 'always run' : 'never run'

Coverage would return:
{'coverage_example.rb' =>
[
{
0..28 => 1
},
{
0..21 => 1,
22..33 => 0
}
]
}
=end

Hello, sorry for very late response...

I agree that C1 coverage is very helpful. But I have no plan to
implement the feature. It will be a tough task.

Your contribution is wanted. If anyone writes a patch, please
send us.

Branch coverage has been already implemented at #13901 and released in Ruby 2.5.0.
Closing this ticket. Sorry for leaving it untouched.

Of course, your contribution is welcome. You may want to read:

I'm unsure if these docs are good enough, though.
