ri fails in 1.9 mode
--------------------
Key: JRUBY-4411
URL: http://jira.codehaus.org/browse/JRUBY-4411
Project: JRuby
Issue Type: Bug
Components: Ruby 1.9
Affects Versions: JRuby 1.5
Environment: JVM 1.5 on Leopard PPC
Reporter: Ian Dees
Assignee: Thomas E Enebo
Fix For: JRuby 1.5
Attachments: 0001-Fixed-ri-for-1.9-mode.patch
Running the following command:
{noformat}
jruby --1.9 -S ri --help
{noformat}
... yields the following error:
{noformat}
/path/to/jruby/bin/ri:44:in `require': no such file to load --
rdoc/ri/ri_driver (LoadError)
from /path/to/jruby/bin/ri:44
{noformat}
It looks like the {{ri}} files have been reorganized a bit in 1.9. The
following code in {{ri}}:
{noformat}
require 'rdoc/ri/ri_driver'
ri = RiDriver.new
ri.process_args
{noformat}
... needs to do something like this instead for 1.9:
{noformat}
require 'rdoc/ri/driver'
RDoc::RI::Driver.run
{noformat}
The attached patch rescues the {{LoadError}} and falls back to the 1.9 method;
the included test case tries {{ri}} in both 1.8 and 1.9 modes.
