I'd love to have something like this http://stackoverflow.com/questions/32863807/visual-studio-code-redirect-input-on-debug without a workaround. That is, ability to redirect input from a given file, when debugging.

I have tried to add arg option in launch.json,

    "configurations": [
        {
            "name": "Python: Debug",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "args": ["<",
                "input.txt"
            ]
        }
    ]

but the launch command doesn't work as usual. The terminal hangs and after I type enter, I got a exception.

Exception has occurred: ValueError
invalid literal for int() with base 10: '

The python script:

n = int(input())
print(n)

The input.txt content:
5

Is there any suggestion?

    This didn't work, because stuff like < or | aren't command line arguments in a proper sense - they're shell operators. When you use them in "args", it will just quote and/or escape them to make sure that they are, in fact, interpreted as arguments rather than operators.

    For it to work properly, we'd need to support it specifically. But for us to support redirection, the "runInTerminal" request in VSCode would need to support it first, since we rely on that to spawn the debuggee.

    I'm going to leave this open as an enhancement, so that we can gauge interest in this feature from the votes.
