Ultraviolet is a syntax highlighting library and engine. It
uses TextMate[http://macromates.com/] syntax files and parses
them using the Textpow[http://textpow.rubyforge.org] library. It
supports more than 60 programming languages out of the box.
It wasn’t clear from the web site, but I needed to install oniguruma
first
from here: サービス終了のお知らせ
sudo gem install ultraviolet
should work.
I say “should” because the textpow gem 404’ed at URL RubyGems.org | your community gem host.
I see this version was just released and it apparently hasn’t been
propagated to all the mirrors yet.
However, did you use “rake publish_packages”? I’ve had that fail to
actually
copy the files successfully in the past, even though rubyforge shows
them
there. (I think it turned out to be a rubygems bug in at the time…)
