How to remove installed ri and rdoc?

Question

How can I remove the ri and rdoc of installed gems? Thanks

Answer 1

I just had this problem to, after thinking it would be a good idea to have some local rdoc for the train etc, I completely filled up my disc!

So, I bit the bullet, and did it (the hard way).

First, this is how I got in this stupid predicament :-

$ gem install rdoc-data
$ rdoc-data --install
$ gem rdoc --all --overwrite

To undo this, I thought I'd uninstall the gems, and then install them as needed (but without rdoc!)

1. Get list :-

   $ gem list
   
   *** LOCAL GEMS ***
   
   aasm (2.1.1)
   actionmailer (3.2.3, 3.2.2, 3.1.4, 3.1.3, 3.1.1, 3.1.0, 2.3.8, 2.3.5)
   actionpack (3.2.3, 3.2.2, 3.1.4, 3.1.3, 3.1.1, 3.1.0, 2.3.8, 2.3.5)
   active_support (3.0.0)
   ... +100 ...
   

2. Copy and search/replace \(.*\) with '\'

3. Bulk uninstall :-

   $ gem uninstall actionmailer \
   actionpack \
   active_support \
   ... 100 more ...
   ZenTest \
   -a -x -I
   

4. Watch as the disc gains GB's of free space! (~11GB!)

Twas a stupid idea in the first place, and my solution may be just as much so, but it worked.
