Subject: Readline and conditional tab results based on input

Hi there,

is there a way to "find out" what a user already typed in readline?

Reason is, i am fetching user input like so:


  user_input = Readline.readline(' Input name of a dir, then press
<TAB>'+"\n",true)

And with Readline.completion_proc i have code that will return only dirs
in this directory. But I would like to invoke this specific code part
only
when a user typed in i.e. "cd "

So if i have a directory called "foobar" it should work here:


"cd foo<TAB>"  # completed to foobar

but if the user would type

"blabalblabla foo<TAB>" # there should be no result
