How do I run nokogiri tests in JRuby?

[Dmitry Ratnikov]

I ran into a minor issue with nokogori (https://github.com/tenderlove/
nokogiri/blob/master/lib/nokogiri/html/document.rb#L183
throwing :encoding_found.to_s but catching a symbol) and wanted to run
the tests to see if they passed. However, I ran into:

bash-3.2$ rake test

I dug a little bit further and it seems like the issue is within racc.
But the latest repo I found has been updated 6 months ago and it also
seems like although it does mention java in the Makefile, it still
installs C bindings when doing gem install. Perhaps I am doing
something very wrong?

PS Another fellow #jruby-er ran into the same problem when trying to
run nokogiri tests, so it seems like the issue is not limited to my
setup.

Hello,

racc and rexical should be built under an MRI version of ruby. Try something like this (assuming presence of RVM):

rvm_use jruby-1.6.5

bundle exec rake clean clobber

rvm_use 1.8.7

bundle exec rake generate # uses racc and rexical to build lexer/parser code

rvm_use jruby-1.6.5

bundle exec rake

setup.

Thanks, I'll try that!

So is racc is not jruby compatible? I've poked into its source a
little bit (github.com/tenderlove/racc version) and seems like the
extensions Makefile does mention java...

Try that and make sure you are using JRuby when you run rake.

You need to run rake on MRI just once. After you get racc generated
files, you don't need MRI anymore.

As far as I know, racc doesn't work on JRuby. Is it changed?
