Custom CLI

ruby-talk
1

I have to create an interface to allow several users to perform various
tasks over ssh. The users will have different permissions.

I want to create a custom shell/CLI to be set as the users shell when they
log in. The interface should have scroll back, command line editing and
history like a normal shell. The commands would be custom commands, i.e.
no relation to system commands.
Is there any library, framework or something to make this easy with ruby?

`readline` is part of the stdlib. It's not documented in rdoc, but
more or less trivial to use once you've looked at the examples in the
distribution.

i would customize irb. for example

   harp:~ > cat a.rb
   def ls g = '*'
     Dir.glob(g){|entry| puts entry}
   end

   def cd d = File.expand_path('~')
     Dir.chdir d
   end

   irb:~ > irb -r ./a.rb
   irb(main):001:0> ls 'skype*'
   skype-1.2.0.18
   skype-1.3.0.53
   skype_staticQT-1.3.0.53-generic.tar.bz2
   => nil

   irb(main):002:0> cd '/tmp'
   => 0

others have done this extensively - check out the raa

cheers
