zLisp (Zealand LISP) is a turing complete lisp interpreted programming languged developed for Zealand as part of a final project assignment.
As the project does not have any portable executable the user is required to compile the source code to run it.
It can be done by:
- Visual Studio
- Open the solution file and run
- netcore cli
- by running `dotnet run` inside the ConsoleRun folder
There are two ways one can use zLisp
The easiest is to use it as a standalone REPL, a Read-Eval-Print-Loop, that launches a environment where you can execute your code and normal fashion.
$ dotnet run

Welcome to Zealand LISP, a crude lisp implementation done in C#
By Samuel Asvanyi for a school project @ Zealand 2021
zLisp > (def x 123)
zLisp > (println x)
123
zLisp > (def x "hello World!")
zLisp > (println x)
hello World!
zLisp >
Second way is to use the library inside your C# code where you would like to expose a part of your program with out having to create a seperate API for your application. You can use the zLisp library and let the user provide you with the code where you can chose to expose certain functions to them.
using ZLisp.Runtime;
Runtime.Eval("(def not (fn (a) (if a false true)))"); // will define a not
function
var results = Runtime.Eval("(not true)");
Console.WriteLine(results); // false
Runtime.Env.Set(new Symbol("is2"), new Func(a => ((Types.Integer)a[0]).Value == 2););
Console.WriteLine(Runtime.Eval("(is2 2)")); // true
Console.WriteLine(Runtime.Eval("(is2 4)")); // false
