Add metadata files for atty. am: 14484ce0b3 am: 1d10dcacc5 am: 9fdc6a6b9f Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/atty/+/1620968 Change-Id: I17f4343b06c05dcc5aef5973273476f4c4b65fe1
are you or are you not a tty?
Add the following to your Cargo.toml
[dependencies] atty = "0.2"
use atty::Stream; fn main() { if atty::is(Stream::Stdout) { println!("I'm a terminal"); } else { println!("I'm not"); } }
This library has been unit tested on both unix and windows platforms (via appveyor).
A simple example program is provided in this repo to test various tty's. By default.
It prints
$ cargo run --example atty stdout? true stderr? true stdin? true
To test std in, pipe some text to the program
$ echo "test" | cargo run --example atty stdout? true stderr? true stdin? false
To test std out, pipe the program to something
$ cargo run --example atty | grep std stdout? false stderr? true stdin? true
To test std err, pipe the program to something redirecting std err
$ cargo run --example atty 2>&1 | grep std stdout? false stderr? false stdin? true
