Multi-line statements not being counted accurately

[adampope]

I'm using 0.10 on a Rails 4.2 project with ruby 2.0.0-p643. I'm seeing lots of occurrences of statements that span multiple lines not being counted as covered, or only 1 or the multiple lines being counted. For example, I have a concern which is completely tested but reports as 77%.

If I simply reformat the code onto single lines I get 100% coverage.

so that we can reproduce this, can you provide a small snippet of the code and tests that create this bug? It would be of great help.

@bf4 I've created a repo with the code to reproduce this in (https://github.com/adampope/simplecov-multi-line-repro). In doing so I've found the cause. We are using the following snippet in test_helper.rb (from #16) to make sure that all files are loaded:

  all_files = Dir['**/*.rb']
  base_result = {}
  all_files.each do |file|
    absolute = File::expand_path(file)
    lines = File.readlines(absolute, :encoding => 'UTF-8')
    base_result[absolute] = lines.map do |l|
      l.strip!
      l.empty? || l =~ /^else$/ || l =~ /^end$/ || l[0] == '#' ? nil : 0
    end
  end

  SimpleCov.at_exit do
    merged = SimpleCov::Result.new(Coverage.result).original_result.merge_resultset(base_result)
    result = SimpleCov::Result.new(merged)
    result.format!
  end

With that code multi-line statements do not get counted correctly.

Any ideas on ways to modify this to correctly handle the multi-line statements?

We found a better way of solving the problem of tracking all files, I've added a comment to #16 so I'll close this ticket.

@bf4 @adampope Hey. What is the final fix for multi line statements. Please help.
