# Colors [![Current Crates.io Version](https://img.shields.io/crates/v/owo-colors.svg)](https://crates.io/crates/owo-colors) [![docs-rs](https://docs.rs/owo-colors/badge.svg)](https://docs.rs/owo-colors) ![MSRV 1.51+](https://img.shields.io/badge/rustc-1.51+-blue.svg) ![Downloads](https://img.shields.io/crates/d/owo-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`](https://docs.rs/owo-colors/latest/owo_colors/fn.set_override.html) * [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](https://crates.io/crates/colored), allowing colored to work in a no_std environment. No allocations 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 owo_colors::OwoColorize; use owo_colors::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" .if_supports_color(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)
