Expand description

A style is a collection of properties that can format a string using ANSI escape codes.

Examples

use nu_ansi_term::{Style, Color};

let style = Style::new().bold().on(Color::Black);
println!("{}", style.paint("Bold on black"));

Fields

foreground: Option<Color>

The style’s foreground color, if it has one.

background: Option<Color>

The style’s background color, if it has one.

is_bold: bool

Whether this style is bold.

is_dimmed: bool

Whether this style is dimmed.

is_italic: bool

Whether this style is italic.

is_underline: bool

Whether this style is underlined.

is_blink: bool

Whether this style is blinking.

is_reverse: bool

Whether this style has reverse colors.

is_hidden: bool

Whether this style is hidden.

is_strikethrough: bool

Whether this style is struckthrough.

Implementations

The prefix bytes for this style. These are the bytes that tell the terminal to use a different color or font style.

Examples

use nu_ansi_term::{Style, Color::Blue};

let style = Style::default().bold();
assert_eq!("\x1b[1m",
           style.prefix().to_string());

let style = Blue.bold();
assert_eq!("\x1b[1;34m",
           style.prefix().to_string());

let style = Style::default();
assert_eq!("",
           style.prefix().to_string());

The infix bytes between this style and next style. These are the bytes that tell the terminal to change the style to next. These may include a reset followed by the next color and style, depending on the two styles.

Examples

use nu_ansi_term::{Style, Color::Green};

let style = Style::default().bold();
assert_eq!("\x1b[32m",
           style.infix(Green.bold()).to_string());

let style = Green.normal();
assert_eq!("\x1b[1m",
           style.infix(Green.bold()).to_string());

let style = Style::default();
assert_eq!("",
           style.infix(style).to_string());

The suffix for this style. These are the bytes that tell the terminal to reset back to its normal color and font style.

Examples

use nu_ansi_term::{Style, Color::Green};

let style = Style::default().bold();
assert_eq!("\x1b[0m",
           style.suffix().to_string());

let style = Green.normal().bold();
assert_eq!("\x1b[0m",
           style.suffix().to_string());

let style = Style::default();
assert_eq!("",
           style.suffix().to_string());

Creates a new Style with no properties set.

Examples

use nu_ansi_term::Style;

let style = Style::new();
println!("{}", style.paint("hi"));

Returns a Style with the bold property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().bold();
println!("{}", style.paint("hey"));

Returns a Style with the dimmed property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().dimmed();
println!("{}", style.paint("sup"));

Returns a Style with the italic property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().italic();
println!("{}", style.paint("greetings"));

Returns a Style with the underline property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().underline();
println!("{}", style.paint("salutations"));

Returns a Style with the blink property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().blink();
println!("{}", style.paint("wazzup"));

Returns a Style with the reverse property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().reverse();
println!("{}", style.paint("aloha"));

Returns a Style with the hidden property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().hidden();
println!("{}", style.paint("ahoy"));

Returns a Style with the strikethrough property set.

Examples

use nu_ansi_term::Style;

let style = Style::new().strikethrough();
println!("{}", style.paint("yo"));

Returns a Style with the foreground color property set.

Examples

use nu_ansi_term::{Style, Color};

let style = Style::new().fg(Color::Yellow);
println!("{}", style.paint("hi"));

Returns a Style with the background color property set.

Examples

use nu_ansi_term::{Style, Color};

let style = Style::new().on(Color::Blue);
println!("{}", style.paint("eyyyy"));

Return true if this Style has no actual styles, and can be written without any control characters.

Examples

use nu_ansi_term::Style;

assert_eq!(true,  Style::default().is_plain());
assert_eq!(false, Style::default().bold().is_plain());

Paints the given text with this color, returning an ANSI string.

Trait Implementations

Returns a copy of the value. Read more

Performs copy-assignment from source. Read more

Styles have a special Debug implementation that only shows the fields that are set. Fields that haven’t been touched aren’t included in the output.

This behaviour gets bypassed when using the alternate formatting mode format!("{:#?}").

use nu_ansi_term::Color::{Red, Blue};
assert_eq!("Style { fg(Red), on(Blue), bold, italic }",
           format!("{:?}", Red.on(Blue).bold().italic()));

Formats the value using the given formatter. Read more

Returns a style with no properties set. Formatting text using this style returns the exact same text.

use nu_ansi_term::Style;
assert_eq!(None,  Style::default().foreground);
assert_eq!(None,  Style::default().background);
assert_eq!(false, Style::default().is_bold);
assert_eq!("txt", Style::default().paint("txt").to_string());

You can turn a Color into a Style with the foreground color set with the From trait.

use nu_ansi_term::{Style, Color};
let green_foreground = Style::default().fg(Color::Green);
assert_eq!(green_foreground, Color::Green.normal());
assert_eq!(green_foreground, Color::Green.into());
assert_eq!(green_foreground, Style::from(Color::Green));
