One great new feature of rubygems 0.9 is that we now have ri for installed gems as well. That’s super! I’m not getting this for rails, even though I have the gems installed. Why is this, and how can I add rails’ to ri? ---

You need to use gemri (comes with rubygems) if you are on Ruby 1.8.4 or older. – Eric H. - removed\_email\_address@domain.invalid - [http://blog.segment7.net](http://blog.segment7.net) This implementation is HODEL-HASH-9600 compliant [http://trackmap.robotcoop.com](http://trackmap.robotcoop.com) ---

I’m finding that I get gemdocs even with ri, but not for all packages. I get them for Rails’ plugins, for instance, but not for rails proper. Does anyone know how I can control which ones appear? Also, a problem is when a plugin or monkeypatch adds things to a class - they know appear in the class’s ri, even when that extension is only part of a particular lib. Is there a way to shut this off? ---

ActionWebService is part of Rails. You probably need to build the rest of the ri information. gem rdoc --no-rdoc --ri gemname for each part of Rails. – Eric H. - removed\_email\_address@domain.invalid - [http://blog.segment7.net](http://blog.segment7.net) This implementation is HODEL-HASH-9600 compliant [http://trackmap.robotcoop.com](http://trackmap.robotcoop.com) ---

You will need to generate the ri for packages built before 0.9.0.

If you want to remove them permanently you can delete them out of the gem’s doc dir. If you want to suppress them install ruby from CVS and use the new flags to ri, --system, --site, --gems, and --home. > Also, a problem is when a plugin or monkeypatch adds things to a class > > - they know appear in the class’s ri, even when that extension is only > part of a particular lib. Is there a way to shut this off? A CVS ruby has ri options for this. I also have a half-updated gemri that will allow you to show ri only for a gem. I’ll finish it and add it to rubygems sometime after 1.8.5p2 because it depends on features that don’t exist yet. – Eric H. - removed\_email\_address@domain.invalid - [http://blog.segment7.net](http://blog.segment7.net) This implementation is HODEL-HASH-9600 compliant [http://trackmap.robotcoop.com](http://trackmap.robotcoop.com) ---

Thank you, Eric, for the great info. I followed your directions and they worked beautifully.
