• Super light memory footprint. Based on fast forward Utf8JsonReader. Does not load whole file into memory. Can PrettyPrint gigabyte Json files!
• Configuration is per printer, and not global.
• Useful .Dump() extensions for objects and strings that will dump the object or json to console.
• Configurable styling based on property name.
• Automatic clipping of strings longer than 200 characters. (Configurable in Config.)

Automatically detect dark and light background

Automatically uses a suitable theme for Light or Dark backgrounds. Totally customisable.

Easy Configuration

using Goblinfactory.PrettyJson;
using static System.ConsoleColor;

var config = PrettyConfig.CreateDefault();

config.LightStyle.Nulls = Red;
config.DarkStyle.Nulls = Red;
config.NumberOfDecimals = 3;
config.IndentWidth = 4;

new PrettyPrinter(config).PrintJson(myData);

Style a value based on it's property name

printer.Config.DarkStyle.ColorsForProps["url"] = Yellow;
printer.Print(new
{
            q1 = new
            {
                question = "What is the best JazzClub in London?",
                options = new[] { "Vortex", "Ronnie Scott", "Pizza Express Jazz Club", "Kansas Smitty�s", "Buster Mantis", "Dalston Jazz Bar" }
            },
            answer = new
            {
                name = "Ronnie Scott",
                description = "As one of the world�s oldest jazz bars, Ronnie Scott�s in Soho has hosted Sarah Vaughan, Count Basie and Miles Davis...",
                attribution = new
                {
                    url = "https://www.standard.co.uk/culture/music/best-jazz-bars-and-clubs-in-london-a3843231.htmlhttps://www.standard.co.uk/culture/music/best-jazz-bars-and-clubs-in-london-a3843231.html",
                    name = "Evening Standard"
                }
            }
});

gives you ...

Super useful .Dump() extentions

	printer.Config.DarkStyle.Dump();
	new { Hat = "Large", Cat = "Zeus"}.Dump();

EasyRead mode (availabe in version 0.2 onwards)

Easyread removes all the quotes and formats the property names with a default 10 character width. (configurable)

 printer.Config.EasyRead = true;
printer.PrintJson(data);

Limitations and final thoughts

• Does not do any encoding other than replace \ with \\, and " with \"
• See StringExtensions.cs for the string encoding.
• If you need additional encodings, please submit a PR for me to review and if it makes sense, or extend the configuration to configure diffrerent types of encoding if needed.
• This is a very small project, feel free to fork it and make your own variant. It could easily be entirely encapsulated in a single file.
• todo: provide an easyread format, which excludes commas and quotes with field padding to align property values. Similar to Yaml formatting.
