Module: Rcov::REXMLExtensions::PrettyFormatterWrapFix

Defined in:
lib/rcov/rexml_extensions.rb

Overview

Fix for this bug: clint-hill.com/2008/10/02/a-bug-in-ruby-did-i-just-find-that/ Also known from this fun exception:

/usr/local/ruby/lib/ruby/1.8/rexml/formatters/pretty.rb:131:in
`[]': no implicit conversion from nil to integer (TypeError)

This bug was fixed in Ruby with this changeset svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=19487 …which should mean that this bug only affects Ruby 1.8.6. The latest stable version of 1.8.7 (and up) should be fine.
