ruby - How to use interactive_editor when REPL console is run in context of a particular object -

i trying programmatically launch console such that:

• its context bound particular object (link stack overflow).
• it allows me use tools (i.e. vim command) provided interactive_editor gem (link github).

it appear 2 conditions trying meet mutually exclusive. below write script fires repl bound context of [1,2,3] list.

# test.rb require 'ripl' require 'interactive_editor'  ripl.start :binding => [1,2,3].instance_eval { binding } 

if run ruby test.rb, can see in context of [1,2,3]:

>> self => [1, 2, 3] >> map { |a| * 2 } => [2, 4, 6] 

but if try using interactive_editor's features:

>> vim "something" => [1, 2, 3] 

this last line fires vim , writes file "something" (without explicit saving):

# --- - 1 - 2 - 3 

is there way me resolve problem? should file issue on interactive_editor gem? same kinds of error occur when use irb along interactive_editor or irbtools.

my guess changing context makes rather difficult interactive_editor resolve object definitions not sure how works.

thanks in advance , please let me know if omitted important information.

1. ruby 2.1.5p273 (2014-11-13 revision 48405) [x86_64-darwin14.0]
2. iteractive_editor (0.0.10)
3. irbtools (2.0.1, 1.7.1)
4. ripl (0.7.1)
5. ripltools (0.7.0)

i running os x yosemite 10.10.3 have managed replicate issue on several other linux boxes.

i found way around this:

def edit(*args)   system("$editor #{args.join(' ')") end 

this still doesn't explain why can't example work interactive_prompt.
