# Colored
[](https://travis-ci.org/mackwic/colored) [](https://crates.io/crates/colored) [](https://github.com/mackwic/colored/blob/master/LICENSE)
Coloring terminal so simple, you already know how to do it!
```rust
"this is blue".blue();
"this is red".red();
"this is red on blue".red().on_blue();
"this is also red on blue".on_blue().red();
"bright colors are welcome as well".on_bright_blue().bright_red();
"you can also make bold comments".bold();
println!("{} {} {}", "or use".cyan(), "any".italic().yellow(), "string type".cyan());
"or change advice. This is red".yellow().blue().red();
"or clear things up. This is default color and style".red().bold().clear();
"purple and magenta are the same".purple().magenta();
"and so are normal and clear".normal().clear();
"you can specify color by string".color("blue").on_color("red");
String::from("this also works!").green().bold();
format!("{:30}", "format works as expected. This will be padded".blue());
format!("{:.3}", "and this will be green but truncated to 3 chars".green());
```
## How to use
Add this in your `Cargo.toml`:
```toml
[dependencies]
colored = "1.8"
```
and add this to your `lib.rs` or `main.rs`:
```rust
extern crate colored; // not needed in Rust 2018
use colored::*;
// test the example with `cargo run --example most_simple`
fn main() {
// TADAA!
println!("{} {} !", "it".green(), "works".blue().bold());
}
```
## Features
- Safe rust, easy to use, minimal dependencies, complete test suite
- Respect the `CLICOLOR`/`CLICOLOR_FORCE` behavior (see [the specs](http://bixense.com/clicolors/))
- Respect the `NO_COLOR` behavior (see [the specs](https://no-color.org/))
- Works on Linux, MacOS, and Windows (Powershell)
#### Colors:
- black
- red
- green
- yellow
- blue
- magenta (or purple)
- cyan
- white
Bright colors: prepend the color by `bright_`. So easy.
Background colors: prepend the color by `on_`. Simple as that.
Bright Background colors: prepend the color by `on_bright_`. Not hard at all.
#### Styles:
- bold
- underline
- italic
- dimmed
- reversed
- blink
- hidden
- strikethrough
You can clear color _and_ style anytime by using `normal()` or `clear()`
#### Advanced Control:
##### Dynamic color from str
As `Color` implements `FromStr`, `From<&str>`, and `From<String>`, you can easily cast a string into a color like that:
```rust
// the easy way
"blue string yo".color("blue");
// this will default to white
"white string".color("zorglub");
// the safer way via a Result
let color_res : Result<Color, ()> = "zorglub".parse();
"red string".color(color_res.unwrap_or(Color::Red));
```
##### Colorization control
If you want to disable any coloring at compile time, you can simply do so by
using the `no-color` feature.
For example, you can do this in your `Cargo.toml` to disable color in tests:
```toml
[features]
# this effectively enable the feature `no-color` of colored when testing with
# `cargo test --feature dumb_terminal`
dumb_terminal = ["colored/no-color"]
```
You can use have even finer control by using the
`colored::control::set_override` method.
## Todo
- **More tests ?**: We always welcome more tests! Please contribute!
## Credits
This library wouldn't have been the same without the marvelous ruby gem [colored](https://github.com/defunkt/colored).
Thanks for the [ansi\_term crate](https://github.com/ogham/rust-ansi-term) for
providing a reference implementation, which greatly helped making this crate
output correct strings.
