redirecting input from file

[peppedilillo]

Hello. I have an application (call it myapp) which takes a variadic argument. For example, I can call the application with: myapp input1 input2. I would like to accept inputs from the stdin stream so that they could be redirected from a file. In this situation, given a file input.txt, like this:

input1 input2

Running the application via myapp < input.txt would run with the same result of myapp input1 input2. I realize this is a stretch but .. Is this possible somehow with click?

EDIT: realized this can be easily achieved with xargs or cat, e.g. xargs input.txt myapp. Thank you!
