Open Pipe Kit collects data using interchangeable drivers for sensors and databases. You can write your own driver in any language you want because every driver is a command line inerface (CLI). How do you turn your program into a CLI? Two things. You add #!/bin/env yourLanguage to the top of the file and then on the command line you run chmod +x your-file. Now you can execute it from the command line by type ./you-file. We've come up with a couple of conventions along the way as we've been creating our own CLI. First you'll notice is that if you are writing a sensor CLI, we name our file pull. If we are writing a database CLI, we name our file push. To send the output of a pull to a push, you just have to place the Unix pipe character between the two commands. For example, ./pull | ./push. Push drivers often require to know where to push data to, like the URL of a database. For that we use parameters like ./pull | ./push --url=http://mydatabase.net. If you haven't written a program before that takes the input of CLI parameters, don't fret. There are plenty of good libraries for making that easy in every language.
