Yansi

A dead simple ANSI terminal color painting library.

Usage

In your Cargo.toml:

[dependencies]
yansi = "1.0"

In your source code:

use yansi::Paint;

println!("Testing, {}, {}, {}!",
    "Ready".bold(),
    "Set".black().on_yellow().invert().italic(),
    "STOP".white().on_red().bright().underline().bold());

See the rustdocs for complete usage details.

Features

Why yet another ANSI terminal coloring library? Here are some reasons:

• This library makes simple things simple: use Paint and go!
• Zero dependencies by default. It really is simple.
• Zero allocations except as needed by opt-in wrapping.
• Automatic Windows support for the vast majority (95%+) of Windows users.
• Featureful no_std, no-alloc, support with default-features = false.
• Style constructors are const: store styles statically, even with dynamic conditions!
• Any type implementing a formatting trait can be styled, not just strings.
• Styling can be enabled and disabled globally and dynamically, on the fly.
• A Style can be predicated on arbitrary conditions.
• Formatting specifiers like {:x} and {:08b} are supported and preserved!
• Built-in (optional) conditions for TTY detection and common environment variables.
• Arbitrary items can be masked for selective disabling.
• Styling can wrap to preserve styling across resets.
• Styling can linger beyond a single value.
• Experimental support for hyperlinking is included.
• The name yansi is pretty cool 😎.
