There's a good command interpreter for ruby instead of irb? Like
ipython for python?

2

How is ipython better than irb?

I've been using wirble which improves irb a bit (although I hate that
it doesn't allow duplicate entries in the history --anyone know how to
fix?).

What functionality are you missing in IRB?

Kind regards

i always hated that it would store history entries in oldest-first
order. so i just copied the code for save_history from wirble.rb
into my .irbrc and adjusted it accordingly:

  require 'wirble'

  # save history newest-first, instead of default oldest-first
  class Wirble::History
    def save_history
      return unless Object.const_defined? :IRB

      path, max_size, perms = %w{path size perms}.map { |v| cfg(v) }

      # read lines from history, and truncate the list (if necessary)
      #lines = Readline::HISTORY.to_a.uniq
      lines = Readline::HISTORY.to_a.reverse.uniq.reverse
      lines = lines[-max_size..-1] if lines.size > max_size

      # write the history file
      real_path = File.expand_path(path)
      File.open(real_path, perms) { |fh| fh.puts lines }
      say 'Saved %d lines to history file %s.' % [lines.size, path]
    end
  end

you could simply change the line that fills the 'lines' array to
something like this:

      lines = Readline::HISTORY.to_a

I believe what he's looking for is a *nix command shell (like sh) that
implements ruby scripting language features.

awesome. thanks jens.

maybe i'll do a little work on wirble to make it more flexible for
variant preferences like ours and post a patch.

  \#lines = Readline::HISTORY\.to\_a\.uniq
  lines = Readline::HISTORY\.to\_a\.reverse\.uniq\.reverse
  lines = lines\[\-max\_size\.\.\-1\] if lines\.size &gt; max\_size

  \# write the history file
  real\_path = File\.expand\_path\(path\)
  File\.open\(real\_path, perms\) \{ |fh| fh\.puts lines \}
  say &#39;Saved %d lines to history file %s\.&#39; % \[lines\.size, path\]
end

end

something like this:

  lines = Readline::HISTORY\.to\_a
