# 🖍 Kokuban
Kokuban simplifies styling strings in the terminal for .NET applications. (Kokuban is "blackboard" in Japanese.)
Kokuban is based on JavaScript library [Chalk](https://github.com/chalk/chalk) for many of its concepts and some of its code.
## Features
- Expressive API
- Auto detects color support
- Auto enables escape sequence support on Windows 10 20H1 or later
- 256 (8-bit) / TrueColor (24-bit) colors support
## Requirements
- .NET Standard 2.0 or higher
- Linux, macOS, Windows ...
- Windows 10 Anniversary Update or later
## Install
```
dotnet package add Kokuban
```
## Usage
```csharp
using Kokuban;
// Use `+` operator.
Console.WriteLine(Chalk.Red + "Hello");
Console.WriteLine(Chalk.Red + ("Hello " + (Chalk.Underline.BgBlue + "World")) + "!");
// Use indexer.
Console.WriteLine(Chalk.Red.Underline["Hello"]);
Console.WriteLine(Chalk.Red.Underline["Hello " + Chalk.Underline.BgBlue["World"]]);
// Use `ToStyledString` extension method.
Console.WriteLine("Foo Bar Baz".ToStyledString(Chalk.White.Blue));
// Use `Render` method.
Console.WriteLine(Chalk.Rgb(255, 128, 128).Render("Hello Konnichiwa!"));
```
### Nested styles
If you nest styled strings, the styles will be automatically stacked.
```csharp
Console.WriteLine(
Chalk.Bold.Gray.BgYellow[
"＼" +
Chalk.White.BgRed["Hello"] +
" " +
Chalk.White.BgBlue["コンニチハ"] +
"!!／"
]
);
// or
Console.WriteLine(
Chalk.Bold.Gray.BgYellow + (
"＼" + (Chalk.White.BgRed + "Hello") + " " + (Chalk.White.BgBlue + "コンニチハ") + "!!／"
)
);
```
## API
### `Chalk.{.<style>...}[string]` (indexer)
```csharp
Chalk.Red.Underline["Hello"] // => "Hello" (Red + Underlined)
```
### `Chalk.<style>{.<style>...} + string` (`+` operator)
```csharp
(Chalk.Red.Underline + "Hello") // => "Hello" (Red + Underlined)
```
### `ToStyledString` extension method
```csharp
Console.WriteLine("Foo Bar Baz".ToStyledString(Chalk.White.Blue));
```
### `Chalk.Create` method
You can customize the behavior by explicitly instancing the AnsiStyle and use it.
```csharp
var chalk = Chalk.Create(new KokubanOptions
{
// The output will be forced to plain text, whether the terminal supports colors or not.
Mode = KokubanColorMode.None,
});
Console.WriteLine(chalk.Red.Underline["Hello"]); // => "Hello" without escape sequences.
```
### `KokubanColorValue` struct
`KokubanColorValue` struct represents a color of AnsiStyle.
```csharp
var byColor = KokubanColorValue.FromColor(KokubanColor.Blue);
var byCode = KokubanColorValue.FromBasic(31); // 4-bit
var byIndex = KokubanColorValue.FromIndex(196); // 8-bit (Index)
var byRgb = KokubanColorValue.FromRgb(128, 0, 0); // 24-bit
Console.WriteLine(Chalk.Foreground(byColor) + "Foo Bar");
```

## 256 colors (8-bit) and TrueColor (24-bit) support
Kokuban also supports 256 colors (8-bit) and TrueColors (24-bit) on supported terminals, same as [Chalk](https://github.com/chalk/chalk#256-and-truecolor-color-support).
The automatic detection of support states and color downsampling are derived from Chalk.
Kokuban supports ANSI 256-palette index (`Ansi256` method) and RGB format (`Rgb` method). However, Hex format (e.g. `#AABBCC`) is not yet supported.
