Is it possible to pipe input?

[diehard2]

I suppose this is a question/feature request. It would be super useful to be able to pipe commands or redirect to a file. Not sure how one would even go about that. Maybe overloading on ostream. Anyway, super useful library, thanks for the hard work!

The library already supports pipe commands and/or redirects to a file.

For piping commands you can do, for example:

echo "answer 42" | ./complete

Instead, for an example of taking input from a file input.txt and having the output on a file output.txt have a look at: examples/filesession.cpp

Thanks for the reply. What I'm trying to do is

subMenu->Insert(
            "moretest", {"address:port"},
            [](std::ostream& out, const string& arg)
            {
              for(int i = 0; i < 1000; i++ ){
               out << arg << std::endl;
              }
            },
            "Print the reverse string" );

if I do

cli> moretest test | more

it would have the standard more behavior to the screen. Or

cli> moretest test | grep foo

would return lines with "foo" in it to the screen.

Well, that's a feature very hard to implement. Keep in mind that this library is not a replacement for a Linux shell, but a command prompt for your own application.

However, for the first one, you should put the pagination code inside your handler.
