That is at this URL it seems they've brought all the RDOC for each of
the rails areas into one consolidated area. I'm looking for a way to
get this off-line? (I know I can go "gem server" and browse each of
the rails sections one-by-one, however it's as not as quick/useable as
the consolidated version available at the above-mentioned URL).
Take a look at http://railsapi.com/. It's not quite the same form but
the content and interface is there. You might also take a look at
http://railsbrain.com although it's only current to 2.3.2.
Of course, there's always the question of what version / patch level.
That's where there's no substitute for a local gem server.
I second the suggestion for http://railsapi.com/. It allows you to
tailor whatever combination of rails/ruby/a few specific gems apis
together and download them locally to your machine. It's pretty easy
to search and has a nice layout.
