+ ❯ ptrepl git
{ptrepl} ~/Development/Python/ptrepl [master] |19:20:15 07-Feb-18|
+ git ❯

Completion

$ ptrepl git
$ git > sta (press TAB)
# result
$ git > sta
        status
        stage
        stash

Readline like completion(requires READLINE_COMPLETION set to true)

$ ptrepl git
$ git > sta (press TAB)
# result
$ git > sta
stage  stash  status

$ ptrepl git
$ git > (press Escape + !)

# repeat last command
$ git > !!
# repeat 10th command
$ git > !10
# repeat 10th command from bottom of history stack
$ git > !-10
