Colors

A zero-allocation no_std-compatible zero-cost way to add color to your Rust terminal to make people go owo.

Supports:

• [x] All std/core formatters
  • [x] [Display](https://doc.rust-lang.org/std/fmt/trait.Display.html)
  • [x] [Debug](https://doc.rust-lang.org/std/fmt/trait.Debug.html)
  • [x] [Octal](https://doc.rust-lang.org/std/fmt/trait.Octal.html)
  • [x] [LowerHex](https://doc.rust-lang.org/std/fmt/trait.LowerHex.html)
  • [x] [UpperHex](https://doc.rust-lang.org/std/fmt/trait.UpperHex.html)
  • [x] [Pointer](https://doc.rust-lang.org/std/fmt/trait.Pointer.html)
  • [x] [Binary](https://doc.rust-lang.org/std/fmt/trait.Binary.html)
  • [x] [LowerExp](https://doc.rust-lang.org/std/fmt/trait.LowerExp.html)
  • [x] [UpperExp](https://doc.rust-lang.org/std/fmt/trait.UpperExp.html)
• [x] Optional checking for if a terminal supports colors
  • [x] Enabled for CI
  • [x] Disabled by default for non-terminal outputs
  • [x] Overridable by NO_COLOR/FORCE_COLOR environment variables
  • [x] Overridable programatically via set_override
• [x] Dependency-less by default
• [x] Hand picked names for all ANSI (4-bit) and Xterm (8-bit) colors
• [x] Support for RGB colors
• [x] Set colors at compile time by generics or at runtime by value
• [x] All ANSI colors
  • [x] Basic support (normal and bright variants)
  • [x] Xterm support (high compatibility and 256 colors)
  • [x] Truecolor support (modern, 48-bit color)
• [x] Styling (underline, strikethrough, etc)

owo-colors is also more-or-less a drop-in replacement for colored, allowing colored to work in a no_std environment. No allocations, unsafe, or dependencies required because embedded systems deserve to be pretty too uwu.

To add to your Cargo.toml: toml owo-colors = "3"

Example

```rust use owo_colors::OwoColorize;

fn main() { // Foreground colors println!("My number is {:#x}!", 10.green()); // Background colors println!("My number is not {}!", 4.on_red()); } ```

Generic colors

```rust use owocolors::OwoColorize; use owocolors::colors::*;

fn main() { // Generically color println!("My number might be {}!", 4.fg::().bg::()); } ```

Stylize

```rust use owo_colors::OwoColorize;

println!("{}", "strikethrough".strikethrough()); ```

Only Style on Supported Terminals

```rust use owo_colors::{OwoColorize, Stream::Stdout};

println!( "{}", "colored blue if a supported terminal" .ifsupportscolor(Stdout, |text| text.bright_blue()) ); ```

Supports NO_COLOR/FORCE_COLOR environment variables, checks if it's a tty, checks if it's running in CI (and thus likely supports color), and checks which terminal is being used. (Note: requires supports-colors feature)
