Any guesses what this code prints?
SCRIPT_LINES__ = {}
require "rubygems"
puts SCRIPT_LINES__.size
If you thought 0 like me, you are wrong. Its prints 31 with MRI. I was trying
to get IronRuby to work with rcov in the pure Ruby mode, and was completely
baffled why it was not working for IronRuby. Turns out SCRIPT_LINES__ is a
magic constant that contains the mapping from the names of all the loaded files
to their content. There is a comment about it in the IronRuby sources, but it
is an unimplemented feature. The pure-Ruby RCov mode depends on this, and so it
does not work with IronRuby.

Interesting to know though. Thanks for sharing!

Just noticed that RCov can work in pure Ruby mode without the C-based core
known as “rcovrt”. The pure Ruby mode is two orders of magnitude slower. Just
FYI. There is still the issue that it will not profile .NET code…

The core is C-based. Most of it is in Ruby. This is just similar to ruby-debug
which also has a small C-based core. Both would need a small hook from
IronRuby. So its certainly feasible to support it, but at this point, it will
be post-1.0
However, you would only get coverage for Ruby code. For profiling .NET code,
you have to use .NET profilers like the one in VS.

I think rcov is c-based ☹

I know everyone is using IronRuby for their testing, but what about code
coverage? Has anyone tried RCov with a .NET app?
