Decent Readline support for irb/pry on Leopard and above for decent UTF8 input, with RVM

Ensure that your ~/.inputrc contains this

set convert-meta off
set input-meta on
set output-meta on

Install the REAL GNU readline from source

   $ curl ftp://ftp.cwru.edu/pub/bash/readline-6.2.tar.gz | tar xfz - && cd readline-6.2 && ./configure --enable-multibyte && make && sudo make install

or of using homebrew

   $ brew install readline

You can also try the readline RVM package but I never tested whether it has it's multibyte flag on.

Then change the Ruby configure options in RVM

   $ mate ~/.rvmrc

and add

    export ruby_configure_flags="--with-readline-dir=/usr/local"

or, if using homebrew, to 

    export ruby_configure_flags="--with-readline-dir=/usr/local/Cellar/readline/x.x.x"

Rebuild your RVM rubies

    $ rvm uninstall ruby-1.8.7-p330
    $ rvm install ruby-1.8.7-p330

and so on for each ruby (meh). You could also try recompiling the readline extension for each of the installed rubies which will save you some compile time (again, repeat for each Ruby)

    $ cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline
    $ ruby extconf.rb
    $ make install

Hey, I'm looking for a way to get vim editing mode working with pry/irb having set editing-mode vi in ~/.inputrc but in contrast to for example psql or R where this functions, it doesnt by pry/irb. I tried recompiling the ruby using the --with-readline-dir but it didnt work. Can u think of a way to get this working with PRY
