How to prevent installing documentation for gems automatically using gem v. 2.0

Question

Previously set up my system to suppress installing gem documentation with --no-ri and --no-rdoc.

Ruby 2.0.0 and gem 2.0.0 seems to have removed the --no-ri flag (and functionality?).

Even when specifying --no-rdoc, I still get installing documentation:

~/dev/ruby> gem install bundler --no-rdoc
Fetching: bundler-1.3.1.gem (100%)
Successfully installed bundler-1.3.1
Done installing documentation for bundler (0 sec).

How to see whether or not documentation is installed? If it is installed, how to suppress for all gem installs?

Answer 1

As gem help install states:

Usage: gem install GEMNAME [GEMNAME ...] [options] -- --build-flags [options]
...
  Install/Update Options:
    ...
        --[no-]document [TYPES]      Generate documentation for installed gems
                                     List the documentation types you wish to
                                     generate.  For example: rdoc,ri
    -N, --no-document                Disable documentation generation

In short:

• --no-rdoc is now --no-document rdoc

• --no-ri is now --no-document ri.

• You can prevent both from installing with either --no-document or -N.

(Unfortunately as of this writing the documentation on Rubygems.org is currently out-of-date, so ignore that for now.)

The option has changed to --no-document (see http://rubygems.rubyforge.org/rubygems-update/History_txt.html)
