windows1x-virtualterminal-rs

============================

This package provides these features.

- Enable ANSI Escape sequence on Windows1x

- Read one key from the terminal without waiting for the Enter key pressed

Enable ANSI Escape sequence on Windows1x

----------------------------------------

`enable_stdout` and `enable_stderr` set the bit for `ENABLE_VIRTUAL_TERMINAL_PROCESSING` of the console mode.

[examples/color.rs](examples/color.rs)

```rust examples/color.rs

fn main() {

    if let Ok(_) = virtualterminal::enable_stdout() {

        println!("\x1B[36m(enabled)\x1B[0m");

    }

    // When the return value of enable_stdout is dropped,

    // virtual terminal processing is disabled.

    println!("\x1B[36m(disabled)\x1B[0m");

}

```

Read one key from the terminal without waiting for the Enter key pressed

------------------------------------------------

[examples/getkey.rs](examples/getkey.rs)

```rust examples/getkey.rs

fn main() {

    if let Ok(_) = virtualterminal::enable_stdin() {

        if let Ok(_) = virtualterminal::make_raw() {

            if let Ok(key) = virtualterminal::getkey() {

                println!("{}", key.replace("\x1B", "ESC"));

            }

        }

        // When the return value of make_raw() is droppped,

        // the mode is changed to cooked mode.

    }

    // When the return value of enable_stdin() is droppped,

    // virtual_terminal_input is disabled.

}

```

- `virtualterminal::enable_stdin()` enables the virtual terminal input mode of Windows1x.

- `virtualterminal::make_raw()` makes the terminal raw-mode.

This code does NOT work as expected

-----------------------------------

[examples/ng.rs](examples/ng.rs)

```rust examples/ng.rs

fn main() {

    let _ = virtualterminal::enable_stdout().unwrap();

    println!("\x1B[36m(enabled)\x1B[0m");

}

```

The printed text is not colored because the old state is restored by drop before println! is executed.
