After upgrading to 1.8.4 using one-click, ri isn’t working for some items: C:\Documents and Settings\gavin.kistner\>ri Array C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_descriptions.rb:99:in `concat': can't convert nil into Array (TypeError) from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in`merge\_in’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_reader.rb:56:in `get_class' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_reader.rb:52:in`get\_class’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_driver.rb:70:in `report_class_stuff' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:106:in`get\_info\_for’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_driver.rb:135:in `process_args' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:134:in`process\_args’ from C:/ruby/bin/ri.bat:55 ## C:\Documents and Settings\gavin.kistner\>ri Array#concat ## Array#concat array.concat(other\_array) -\> array ``` Appends the elements in other_array to _self_. ["a", "b"].concat( ["c", "d"] ) #=> ["a", "b", "c", "d"] ``` C:\Documents and Settings\gavin.kistner\>ri --version ri v1.0.1 - 20041108 C:\Documents and Settings\gavin.kistner\>ruby --version ruby 1.8.4 (2006-04-14) [i386-mswin32] I found two other references to this in the nntp archive, but no followup responses. Using fxri for Array or String causes fxri to crash (unsurprisingly). I tried regenerating my system-wide ri data, to no avail: C:\ruby\src\ruby-1.8.4\>rdoc -R array.c: c… bignum.c: c… [snip] Generating RI… Files: 83 Classes: 198 Modules: 66 Methods: 2187 Elapsed: 126.922s C:\ruby\src\ruby-1.8.4\>ri Array C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_descriptions.rb:99:in `concat': can't convert nil into Array (TypeError) from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_descriptions.rb:99:in`merge\_in’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_reader.rb:56:in `get_class' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_reader.rb:52:in`get\_class’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_driver.rb:70:in `report_class_stuff' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:106:in`get\_info\_for’ from C:/ruby/lib/ruby/1.8/rdoc/ri/ri\_driver.rb:135:in `process_args' from C:/ruby/lib/ruby/1.8/rdoc/ri/ri_driver.rb:134:in`process\_args’ from C:/ruby/bin/ri.bat:55 Anyone got any groovier suggestions? ---

Can someone please get this patch into the one-click installer so that Ruby doesn’t look broken out of the box when I convince all my friends to install it? 🙂 I mean, our state of documentation is one common sore point (though getting better); to have the documentation totally broken for a couple really core classes is especially bad.
