are you or are you not a tty?
Add the following to your Cargo.toml
toml
[dependencies]
atty = "0.2"
```rust 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
bash
$ cargo run --example atty
stdout? true
stderr? true
stdin? true
To test std in, pipe some text to the program
bash
$ echo "test" | cargo run --example atty
stdout? true
stderr? true
stdin? false
To test std out, pipe the program to something
bash
$ cargo run --example atty | grep std
stdout? false
stderr? true
stdin? true
To test std err, pipe the program to something redirecting std err
bash
$ cargo run --example atty 2>&1 | grep std
stdout? false
stderr? false
stdin? true
