In the version of haml I'm using, it looks like the relevant code is
in vendor/plugins/haml/lib/haml/filters.rb. There is no filters
directory there.
In that file is:
unless defined?(Markdown)
# Uses RedCloth to provide only Markdown (not Textile) parsing
class Markdown < RedCloth
def render
self.to_html(:markdown)
end
end
puts 'Defined Markdown class' # my debugging addition
end
I also put a debugging line at the top of that file and confirmed it
prints when starting the server under both stock Ruby and REE.
However, that debugging line after the Markdown definition only prints
when I start the server using stock Ruby (and not REE).
I then added the line to the section above:
unless NOT_LOADED.include? 'bluecloth'
Markdown = BlueCloth unless defined?(Markdown)
puts 'Testing' # my debugging addition
end
And the line prints on REE but not stock Ruby. So it looks like one is
using RedCloth and one is using BlueCloth?
Then I tried listing gems with both:
# gem list|egrep "(RedCloth|BlueCloth|haml)"
haml (3.0.18)
merb-haml (1.1.3)
RedCloth (4.2.3)
# /opt/ruby-enterprise-1.8.7-2010.02/bin/gem list|egrep "(RedCloth|
BlueCloth|haml)"
BlueCloth (1.0.1)
haml (3.0.18)
merb-haml (1.1.3)
RedCloth (4.2.3)
That's strange, so BlueCloth isn't on standard Ruby, even though I
thought it was. So, I did "gem install bluecloth" on standard Ruby,
only to find that bluecloth and BlueCloth are different gems (wow...).
Doing "gem install BlueCloth" now made both standard and REE show the
same gems.
So now, as predicted, both standard and enterprise Ruby fail with the
same error. So maybe I can just remove BlueCloth entirely and let it
use RedCloth to fix the problem (I'm not sure how those two libraries
are used)? But something still seems wrong. Why am I getting that
uninitialized constant error when BlueCloth is installed?
Thanks again for your help.
