+#![doc(html_root_url = "https://docs.rs/yansi/0.6.0-dev")]
+
+//! A dead simple ANSI terminal color painting library.
+//!
+//! # Usage
+//!
+//! Usage is best illustrated via a quick example:
+//!
+//! ```rust
+//! use yansi::{Paint, Color};
+//!
+//! println!("Testing, {}, {}, {}!",
+//! Paint::red(1),
+//! Paint::green(2).bold().underline(),
+//! Paint::blue("3").bg(Color::White).italic());
+//! ```
+//!
+//! ## Paint
+//!
+//! The main entry point into this library is the [`Paint`] type. `Paint`
+//! encapsulates a value of any type that implements the [`Display`] or
+//! [`Debug`] trait. When a `Paint` is `Display`ed or `Debug`ed, the appropriate
+//! ANSI escape characters are emitted before and after the wrapped type's `fmt`
+//! implementation.
+//!
+//! `Paint` can be constructed via [a myriad of methods]. In addition to these
+//! constructors, you can also use the [`color.paint()`](Color::paint()) method
+//! on a given [`Color`] value to construct a `Paint` type. Both of these
+//! approaches are shown below:
+//!
+//! ```rust
+//! use yansi::Paint;
+//! use yansi::Color::Red;
+//!
+//! println!("I'm {}!", Paint::red("red").bold());
+//! println!("I'm also {}!", Red.paint("red").bold());
+//! ```
+//! [`Display`]: ::std::fmt::Display
+//! [`Debug`]: ::std::fmt::Debug
+//! [a myriad of methods]: struct.Paint.html#unstyled-constructors
+//!
+//! ## Styling
+//!
+//! Modifications to the styling of an item can be made via [a number of
+//! chainable methods] on `Paint`.
+//!
+//! ```rust
+//! use yansi::Paint;
+//!
+//! Paint::new("hi").underline().invert().italic().dimmed().bold();
+//! ```
+//!
+//! Styling can also be created independently from a `Paint` structure via the
+//! [`Style`] structure. This allows common styling to be stored and reused. A
+//! `Style` can be applied via the [`style.paint()`] method or the
+//! [`paint.with_style()`] method:
+//!
+//! ```rust
+//! use yansi::{Paint, Color, Style};
+//!
+//! // A bold, itatlic style with red foreground.
+//! let alert = Style::new(Color::Red).bold().italic();
+//!
+//! // Using `style.paint()`; this is preferred.
+//! println!("Alert! {}", alert.paint("This is serious business!"));
+//! println!("Hi! {}", alert.underline().paint("Super serious!"));
+//!
+//! // Using `paint.with_style()`.
+//! println!("Alert! {}", Paint::new("Yet another.").with_style(alert));
+//! ```
+//!
+//! [a number of chainable methods]: struct.Paint.html#setters
+//! [`style.paint()`]: Style::paint()
+//! [`paint.with_style()`]: Paint::with_style()
+//!
+//! # Disabling
+//!
+//! Painting can be disabled globally via the [`Paint::disable()`] method. When
+//! painting is disabled, the `Display` and `Debug` implementations for `Paint`
+//! will emit the `Display` or `Debug` of the contained object and nothing else.
+//! Painting can be reenabled via the [`Paint::enable()`] method.
+//!
+//! One potential use of this feature is to allow users to control color ouput
+//! via an environment variable. For instance, to disable coloring if the
+//! `CLICOLOR` variable is set to `0`, you might write:
+//!
+//! ```rust
+//! # { if false { // we don't actually want to disable coloring
+//! use yansi::Paint;
+//!
+//! if let Ok(true) = std::env::var("CLICOLOR").map(|v| v == "0") {
+//! Paint::disable();
+//! }
+//! # } }
+//! ```
+//!
+//! ## Masking
+//!
+//! Items can be arbitrarily _masked_. When an item is masked and painting is
+//! disabled, the `Display` and `Debug` implementations of `Paint` write
+//! nothing. This allows you to selectively omit output when painting is
+//! disabled. Values can be masked using the [`Paint::masked()`] constructor
+//! or [`paint.mask()`] and [`style.mask()`] style setters.
+//!
+//! [`paint.mask()`]: Paint::mask()
+//! [`style.mask()`]: Style::mask()
+//!
+//! One use for this feature is to print certain characters only when painting
+//! is enabled. For instance, you might wish to emit the 🎨 emoji when
+//! coloring is enabled but not otherwise. This can be accomplished by masking
+//! the emoji:
+//!
+//! ```rust
+//! use yansi::Paint;
+//!
+//! println!("I like colors!{}", Paint::masked(" 🎨"));
+//! ```
+//!
+//! This will print "I like colors! 🎨" when painting is enabled and "I like
+//! colors!" when painting is disabled.
+//!
+//! ## Wrapping
+//!
+//! Styling can be set to _wrap_ existing styles using either the
+//! [`Paint::wrapping()`] constructor or the [`paint.wrap()`] and
+//! [`style.wrap()`] style setters. When a style is _wrapping_, all color
+//! resets written out by the internal item's `Display` or `Debug`
+//! implementation are set to the styling of the wrapping style itself. In other
+//! words, the "default" style of the wrapped item is modified to be the
+//! wrapping style. This allows for easy wrapping of other colored text. Without
+//! this feature, the console would reset styling to the terminal's default
+//! style instead of the wrapping style.
+//!
+//! [`paint.wrap()`]: Paint::wrap()
+//! [`style.wrap()`]: Style::wrap()
+//!
+//! One use for this feature is to ensure that styling is consistently set
+//! across items that may already be styled, such as when logging.
+//!
+//! ```rust
+//! use yansi::{Paint, Color};
+//!
+//! let inner = format!("{} and {}", Paint::red("Stop"), Paint::green("Go"));
+//! println!("Hey! {}", Paint::wrapping(inner).fg(Color::Blue));
+//! ```
+//!
+//! This will print 'Hey!' unstyled, "Stop" in red, "and" in blue, and "Go" in
+//! green. Without wrapping, "and" would be unstyled as `Paint::red()` resets
+//! the style after printing the internal item.
+//!
+//! # Windows
+//!
+//! Coloring is supported on Windows beginning with the Windows 10 anniversary
+//! update. Since this update, Windows consoles support ANSI escape sequences.
+//! This support, however, must be explicitly enabled. `yansi` provides the
+//! [`Paint::enable_windows_ascii()`] method to enable ASCII support on Windows
+//! consoles when available.
+//!
+//! ```rust
+//! use yansi::Paint;
+//!
+//! // Enable ASCII escape sequence support on Windows consoles.
+//! Paint::enable_windows_ascii();
+//! ```
+//!
+//! You may wish to disable coloring on unsupported Windows consoles to avoid
+//! emitting unrecognized ASCII escape sequences:
+//!
+//! ```rust
+//! use yansi::Paint;
+//!
+//! if cfg!(windows) && !Paint::enable_windows_ascii() {
+//! Paint::disable();
+//! }
+//! ```
+//!
+//! [`Paint::enable_windows_ascii()`]: Paint::enable_windows_ascii()
+//!
+//! # Why?
+//!
+//! Several terminal coloring libraries exist ([`ansi_term`], [`colored`],
+//! [`term_painter`], to name a few), begging the question: why yet another?
+//! Here are a few reasons:
+//!
+//! * This library is _much_ simpler: there are three types!
+//! * Unlike [`ansi_term`] or [`colored`], _any_ type implementing `Display`
+//! or `Debug` can be stylized, not only strings.
+//! * Styling can be enabled and disabled globally, on the fly.
+//! * Arbitrary items can be [_masked_] for selective disabling.
+//! * Styling can [_wrap_] any arbitrarily styled item.
+//! * Typically only one type needs to be imported: [`Paint`].
+//! * Zero dependencies. It really is simple.
+//! * The name `yansi` is pretty short.
+//!
+//! All that being said, this library borrows API ideas from the three libraries
+//! as well as implementation details from [`ansi_term`].

+/// # Method Glossary
+///
+/// The `Style` structure exposes many methods for convenience. The majority of
+/// these methods are shared with [`Paint`](Paint).
+///
+/// ### Foreground Color Constructors
+///
+/// Return a new `Style` structure with a foreground `color` applied.
+///
+/// * [`Style::new(color: Color)`](Style::new())
+///
+/// ### Setters
+///
+/// Set a style property on a given `Style` structure.
+///
+/// * [`style.fg(color: Color)`](Style::fg())
+/// * [`style.bg(color: Color)`](Style::bg())
+/// * [`style.mask()`](Style::mask())
+/// * [`style.wrap()`](Style::wrap())
+/// * [`style.bold()`](Style::bold())
+/// * [`style.dimmed()`](Style::dimmed())
+/// * [`style.italic()`](Style::italic())
+/// * [`style.underline()`](Style::underline())
+/// * [`style.blink()`](Style::blink())
+/// * [`style.invert()`](Style::invert())
+/// * [`style.hidden()`](Style::hidden())
+/// * [`style.strikethrough()`](Style::strikethrough())
+///
+/// These methods can be chained:
+///
+/// ```rust
+/// use yansi::{Style, Color::{Red, Magenta}};
+///
+/// Style::new(Red).bg(Magenta).underline().invert().italic().dimmed().bold();
+/// ```
+///
+/// ### Converters
+///
+/// Convert a `Style` into another structure.
+///
+/// * [`style.paint<T>(item: T) -> Paint<T>`](Style::paint())
+///
+/// ### Getters
+///
+/// Return information about a `Style` structure.
+///
+/// * [`style.fg_color()`](Style::fg_color())
+/// * [`style.bg_color()`](Style::bg_color())
+/// * [`style.is_masked()`](Style::is_masked())
+/// * [`style.is_wrapping()`](Style::is_wrapping())
+/// * [`style.is_bold()`](Style::is_bold())
+/// * [`style.is_dimmed()`](Style::is_dimmed())
+/// * [`style.is_italic()`](Style::is_italic())
+/// * [`style.is_underline()`](Style::is_underline())
+/// * [`style.is_blink()`](Style::is_blink())
+/// * [`style.is_invert()`](Style::is_invert())
+/// * [`style.is_hidden()`](Style::is_hidden())
+/// * [`style.is_strikethrough()`](Style::is_strikethrough())
+///
+/// ### Raw Formatters
+///
+/// Write the raw ANSI codes for a given `Style` to any `fmt::Write`.
+///
+/// * [`style.fmt_prefix(f: &mut fmt::Write)`](Style::fmt_prefix())
+/// * [`style.fmt_suffix(f: &mut fmt::Write)`](Style::fmt_suffix())
