Devlooped.Spectre.Yaml

Overview

Devlooped.Spectre.Yaml adds a YamlText renderable to Spectre.Console that displays YAML with syntax-highlighted tokens (keys, strings, numbers, booleans, nulls, and comments). It also accepts JSON and arbitrary .NET objects, automatically converting them to YAML before rendering.

Usage

From a YAML string

using Spectre.Console;

AnsiConsole.Write(new YamlText("""
    server:
      host: localhost
      port: 8080
      tls: true
    """));

From a .NET object

using Spectre.Console;

var config = new
{
    Server = new { Host = "localhost", Port = 8080, Tls = true },
    Retries = 3,
    Tags = new[] { "web", "api" },
};

AnsiConsole.Write(new YamlText(config));

System.Text.Json.JsonSerializer serializes the object; the resulting JSON is then converted to YAML. JsonNode and JsonElement overloads are also available.

Inside a Panel

using Spectre.Console;

AnsiConsole.Write(
    new Panel(new YamlText(myObject))
        .Header("Configuration")
        .BorderColor(Color.Yellow)
        .Padding(1, 1));

Customizing colors

Each token type has a configurable Style. Use the fluent extension methods for the most concise syntax:

var text = new YamlText(yaml)
    .KeyColor(Color.Yellow)
    .StringColor(Color.Cyan1)
    .NumberColor(Color.Blue)
    .BooleanColor(Color.Green)
    .NullColor(Color.Grey)
    .CommentColor(Color.DarkSlateGray1);

AnsiConsole.Write(text);

Or assign Style objects directly when you need full control (foreground, background, decorations):

var text = new YamlText(yaml)
{
    KeyStyle    = new Style(Color.Yellow, decoration: Decoration.Bold),
    StringStyle = new Style(Color.Cyan1),
};
