Colour

Macros for creating coloured console output.

General

The following macros are provided:

| Colour | Dark Variant | With LF | Dark With LF | |:-----------|:----------------|:--------------|:-------------------| | black! | N/A | black_ln! | N/A | | red! | dark_red! | red_ln! | dark_red_ln! | | green! | dark_green! | green_ln! | dark_green_ln! | | yellow! | dark_yellow! | yellow_ln! | dark_yellow_ln! | | blue! | dark_blue! | blue_ln! | dark_blue_ln! | | magenta! | dark_magenta! | magenta_ln! | dark_magenta_ln! | | cyan! | dark_cyan! | cyan_ln! | dark_cyan_ln! | | grey! | dark_grey! | grey_ln! | dark_grey_ln! | | white! | N/A | white_ln! | N/A |

The versions with suffix _ln append a newline (similar to print! versus println!).

There are also prnt! and prnt_ln! available which print using the current default foreground colour.

Every variant also has a version with prefix e_. Variants with this prefix output to stderr, while those without the e_ prefix output to stdout.

Example

```rust use colour::*;

fn foo() { let err: Result<(), u8> = Err(1); prntln!("Failed on {}", 9); yellow!("Error details: "); redln!("{:?}", err); }

fn main() { black!("black "); red!("red "); green!("green "); yellow!("yellow "); blue!("blue "); magenta!("magenta "); cyan!("cyan "); grey!("grey "); white!("white "); darkred!("darkred "); darkgreen!("darkgreen "); darkyellow!("darkyellow "); darkblue!("darkblue "); darkmagenta!("darkmagenta "); darkcyan!("darkcyan "); darkgrey!("darkgrey "); prnt!("default colour\n\n"); } ```

Minimum Rust Version
