Hi
Unfortunately I don't remember it. I just remember that I applied a
patch in one of the file of gem.
Apply below patch in var/lib/gems/1.8/gems/htmldoc-0.2.0/lib/htmldoc.rb
file.
@result[:output] = result
result.split("\n").each do |line|
+ line.strip! (patch)
case line
when /^BYTES: (\d+)/
@result[:bytes] = $1.to_i
Patch file is attached.
Let me know if this is worked or not.
Thanks
