setup-console

A library that provides a function to fix ANSI escaping problem in Command Prompt on Windows.

Usage

Simply run setup_console::init() (or setup_console::try_init()) in the main function before printing anything.

fn main() {
    println!("\x1b[31mRed \x1b[32mGreen \x1b[34mBlue\x1b[39m");
    // ･[31mRed ･[32mGreen ･[34mBlue･[39m
    setup_console::init();
    println!("\x1b[31mRed \x1b[32mGreen \x1b[34mBlue\x1b[39m");
    // Red Green Blue
}

Panics

This only applies to Windows.

setup_console::init() doesn't panic, but shows message and terminates program with error code obtained from GetLastError() instead.

The situations that would lead program to terminate would be

• when stdout is invalid (e.g. program 1>nul)
• when program fails to run GetConsoleMode()
• when program fails to run SetConsoleMode()

If this is not your desired behavior, you can use setup_console::try_init() which returns Result.
