When I run this command :

What is the most recent RedCloth gem for jruby?

Redcooth isn't a core dependency and could be removed as gem dep I
think.

I think it's RedCloth 4.0.3 because I see it in my directory
jruby-1.1.3\lib\ruby\gems\1.8\gems\RedCloth-4.0.3 but when I do

C:\>gem search redcloth -b

*** LOCAL GEMS ***

*** REMOTE GEMS ***

RedCloth (4.0.3)


It's not in my Local Gems !?
And when I want to install it I've the same error than newjs

Redcloth doesn't work with this script:

require 'rubygems'
require 'redcloth'

p RedCloth.new("abc foo abc").to_html

Here the error message :
C:\>jruby "C:\redcloth_test.rb"

Maybe a JRuby's bug ? Or a problem with my config...

[Nic Williams]

jruby requires jruby specific gems, if the gem requires installing native extensions (e.g. C code); I guess there is no jruby version of RedCloth.

I've download and install manually the Windows version of Redcloth
gem
gem install c:\RedCloth-4.0.3-x86-mswin32-60.gem

Redcloth didn't seem to work...
But I can successfully install newjs !
Now I'm going to test if newjs is working correctly.

I've found the solution :
The last version of RedCloth isn't compatible with JRuby but the
RedCloth 3.0.x versions are OK.

So, to install correctly newjs on JRuby you have to do :
gem uninstall RedCloth -v 4.0.3
gem install RedCloth -v 3.0.4
gem install newjs

I think you can close this topic.

And like we say in French, Merci Docteur !

Ok, so I shouldn't upgrade the required version of RedCloth in the dependencies. I think I did in newgem, not sure.

You might like to ping the new RedCloth maintainer and ask if they want to release a jruby version. They might not know how.
