Implementations§
source§impl ColorMode
impl ColorMode
With ColorMode
you can implement command line options like --color=auto|on|off
easily.
§Example:
let option = "--color=auto";
let color_mode = match option {
"--color=on" => ColorMode::Off,
"--color=off" => ColorMode::On,
_ => ColorMode::default().eval(),
};
assert!(match color_mode {
ColorMode::On | ColorMode::Off => true,
_ => false
});
sourcepub fn should_colorize(output: Output) -> bool
pub fn should_colorize(output: Output) -> bool
indicates, if the output
is capable of displaying colors and if NO_COLOR
is not active.
sourcepub fn eval(self) -> Self
pub fn eval(self) -> Self
Returns ColorMode::On or ColorMode::Off
§Example:
let on_off = ColorMode::default().eval();
assert!(match on_off {
ColorMode::On | ColorMode::Off => true,
_ => false
});
sourcepub fn use_color(self) -> bool
pub fn use_color(self) -> bool
Indicates if color should be used
§Example:
if ColorMode::default().use_color() {
println!("We can use color! :-)");
} else {
println!("No color for you! :-(");
}
if ColorMode::Auto(Output::StdErr).use_color() {
println!("We can use color on stderr! :-)");
} else {
println!("No color for you on stderr! :-(");
}
assert_eq!(ColorMode::On.use_color(), true);
assert_eq!(ColorMode::Off.use_color(), false);

source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the foreground set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red()
and
green()
, which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg()
:
use yansi::{Paint, Color};
painted.fg(Color::White);
Set foreground color to white using white()
.
use yansi::Paint;
painted.white();
source§fn bright_black(&self) -> Painted<&T>
fn bright_black(&self) -> Painted<&T>
Returns self
with the

fn bright_red(&self) -> Painted<&T>
source§fn bright_green(&self) -> Painted<&T>
fn bright_green(&self) -> Painted<&T>

§Example
println!("{}", value.bright_green());
source§fn bright_yellow(&self) -> Painted<&T>
fn bright_yellow(&self) -> Painted<&T>
Returns self

source§fn bright_magenta(&self) -> Painted<&T>

source§fn bright_cyan(&self) -> Painted<&T>
fn bright_cyan(&self) -> Painted<&T>
source§fn bright_white(&self) -> Painted<&T>
fn bright_white(&self) -> Painted<&T>
Returns self

fg()
set to
Color::BrightWhite
.
§Example
println!("{}", value.bright_white());
source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the background set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red()
and
on_green()
, which have the same functionality but
are pithier.
§Example
Set background color to red using fg()
:
use yansi::{Paint, Color};
painted.bg(Color::Red);
Set background color to red using on_red()
.
use yansi::Paint;
painted.on_red();

source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute
value
.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold()
and
underline()
, which have the same functionality
but are pithier.
§Example
Make text bold using attr()
:
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);
Make text bold using using bold()
.
use yansi::Paint;
painted.bold();
source§fn underline(&self) -> Painted<&T>

set to

source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi
Quirk
value
.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask()
and
wrap()
, which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk()
:
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);
Enable wrapping using wrap()
.
use yansi::Paint;
painted.wrap();
source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting()
due to conflicts with Vec::clear()
.
The clear()
method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting()
due to conflicts with Vec::clear()
.
The clear()
method will be removed in a future release.source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition
value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted
only when both stdout
and stderr
are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
