Robertluo.Edn.Net

My attempt of implementing Edn format for .Net.

Usage

Parse

open Robertluo

Edn.parse "{:hello \"Edn\"}"

var v = Robertluo.Edn.Parse("{:foo/bar 3}");

//to use the value
var m = v.IsEMap ? ((Edn.EMap) v).Item : null;

// to create EDN value {:foo 3} in program
var a = Edn.MapOf(new Tuple<Edn, Edn>[] {new Tuple<Edn, Edn>(Edn.Kw(null, "foo"), Edn.NewEInteger(3L))});
// or simpler and clearer
var a = Edn.Parse("{:foo 3}");

// create a vector edn
var b = Edn.VecOf(new Edn[] { Edn.Kw("foo", "bar"), Edn.NewEBool(false), Edn.NewEString("hello")});
// or simpler
var b = Edn.Parse("[:foo/bar, false, \"Hello\"]");

GetIn

GetIn can quickly pull value from a EDN value.

/// Get in can 
var c = Edn.Parse("[{:a 3 :b \"ok\"} {:a 15, :b nil}]");
WriteLine($"Get in: {c.GetIn(new Edn[] {Edn.NewEInteger(1L), Edn.Kw(null, "a")})}");

Releases

• 0.2.0 with all standard features implemented
• 0.3.0 with some constructor for c# programmer convinience
• 0.4.0 introduce GetIn

Design

The Edn type in Robertluo.Edn is the basic abstraction, it can be:

• Null value nil
• Boolean
• String
• a number
  • as integer (int64)
  • as bigint
  • as float
  • as decimal
• Keyword
• Symbol.
• Set.
• Vector.
• Map.

It also can contains tagged element. (TODO Customizable tag parsing)

Develop

• DotNote Core
• Fake build tool
• Paket packaging manager

So you should install all above tools, then:

1. paket install to install all dependencies
2. dotnet watch -p Test/Edn.Net.Test/Edn.Net.Test.fsproj run to automatically build and run tests.
