Description
ri
in Ruby trunk fails to find documentation for some methods.
Array#append and Array#prepend are new in trunk. ri knows that these methods exist, but has no document for them.
$ ri Array#append
= Array#append
(from ruby core)
------------------------------------------------------------------------------
append(*args)
------------------------------------------------------------------------------
The same problem happens with all methods from rb_define_alias()
in Ruby's source code. For example, Array#size, IO#to_i, Hash#to_s, and Thread#inspect have no document. These are all aliases of other methods that have document.
There is another problem with Queue, an alias for Thread::Queue. ri doesn't know that Queue has methods.
$ ri Queue#push
Nothing known about Queue#push
The command ri Queue
shows the document for the class, but it has no methods. The command ri Thread::Queue
shows methods, but no class document. The same problem happens with other classes in rthread_sync.c, like Mutex.
