Why does Light Table not allow the user to raw-input a string when running a module with the raw_input() function?

[Eliot Cloud]

Whenever I try to run the following program in Light Table:

str1 = raw_input("Enter anything:")

print "raw_input =", str1

The working indicator in the console appears but never disappears and the user, i.e. myself, is not prompted to "Enter anything" as I expect it to. Why?

Details:

Mac OSX 10.9.3.

Python 2.7.5 (default, Mar  9 2014, 22:15:05)

stdio hasn't been implemented, so there's no where for you to put the input.

Cheers,
Chris.

Please explain "stdio hasn't been implemented", i.e. what is "stdio" and how do I implement it?

When you run in a terminal, you automatically have an input stream, "stdin", and an output, "stdout", collectively "stdio". Anything you type goes into the input stream; when you call "raw_input" it waits for something be turn up in that input stream, reads it and returns the result.

In Light Table there's simply no way (yet) to feed input to your program, so Python will wait in vain for some to turn up. A simple text box which feeds text into Python's input stream would do the trick, but noone's felt the need to implement that yet. You could do it yourself but that might be tricky – I'd suggest storing your "input" into variables or passing it directly into functions instead.

It would be good to make the console either contenteditable or a rich input box (or perhaps even its own CM editor instance). Unfortunately, nobody has gotten around to it yet.

Any plans of implementing this feature in the near term?.
