Snap for 9719949 from 34db71c9236860747d30e9de80b654db0f2948f4 to udc-release am: a5cb6beca8 Original change: https://googleplex-android-review.googlesource.com/c/platform/external/rust/crates/atty/+/21946432 Change-Id: I5660105ccbbb9ad7b8ae48920f9f84b6dd14aa1b Signed-off-by: Automerger Merge Worker <[email protected]>
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
