Gotochan for C#

A scripting language to power the universe.

Designed in 2023 and perfected in 2025.

Getting Started

Let's create a basic 'hello world' program:

what = ~hello~world!
goto say

Gotochan does not use type annotations, curly braces, capital letters, or anything else that just gets in the way.

Gotochan is simple and elegant, so everything is accomplished with goto, label and if.

Now let's make a rocket launch.

counter = 10
what = ~countdown:~
what += counter
what += ~\n
goto say
counteriszero = counter == 0
seconds = 0.5
goto wait
counter -= 1
goto +2 if counteriszero
goto -9
what = ~blast~off!
goto say

It's aesthetic. It's easy. You use goto for everything.

But can you goto a goto?

Yes.

goto dosomething

label dosomething
goto goto dosomething

Goto goto goes to the last goto label for a label you've gone to. So you can goto the line after the line of the goto for the label you wanted to go to.

What if you have a lot of goto?

That's okay. Become best friends with goto.

Thingies

There are only four types of thing in Gotochan:

• nothing: the absence of all things
• flag: something that's either there or not there
• number: a numeric value
• string: a list of graphemes

These are the four thingies that make up Gotochan.

Comments

Since Gotochan is a stylistic, elegant language, there's no difficulty in understanding a Gotochan program, so you don't need comments to describe the code. However, comments can be useful for translating to another language.

goto heaven # 天国に行く

Interpreting

Gotochan code can be interpreted with 3 simple steps:

// Read source code
string Source = File.ReadAllText("gotogotchi.gotochan");

// Parse as instructions
ParseResult ParseResult = Parser.Parse(Source).Value;

// Interpret instructions
Actor.Shared.Interpret(ParseResult);

All code runs in an actor which has a lock, variables and gotos.

Compiling

Gotochan code can be compiled to C# code for better performance.

Parse it as normal and then compile it:

// Compile as C# code
CompileResult CompileResult = Compiler.Compile(ParseResult).Value;

Then create a file in your C# project and paste the resulting code.
