We use cargo vendor to generate a .cargo/config file and the vendor directory. Vendoring allows us to lock our dependencies and to modify them easily from the top level Cargo.toml. We vendor all dependencies, including the crates.io ones, which allows for network isolated builds. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

> are you or are you not a tty?
|
|
|
|
|
|
## install
|
|
|
|
Add the following to your `Cargo.toml`
|
|
|
|
```toml
|
|
[dependencies]
|
|
atty = "0.2"
|
|
```
|
|
|
|
## usage
|
|
|
|
```rust
|
|
extern crate atty;
|
|
|
|
use atty::Stream;
|
|
|
|
fn main() {
|
|
if atty::is(Stream::Stdout) {
|
|
println!("I'm a terminal");
|
|
} else {
|
|
println!("I'm not");
|
|
}
|
|
}
|
|
```
|
|
|
|
## testing
|
|
|
|
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
|
|
```
