Welcome dear reader to the GitHub page of my programming language: Pandah Pandah aspires to be a keyword based language that is easily explainable You can read up on how it works below!

--Documentation for the Pandah language--

Chapter 1. Hello World

A pandah program always starts itself in the "Main" function of the "Program" class. to create a running program one should first create this Program class. this is done by typing "class Program" in the first line. like some other languages the class and its name is followed by an "end" An example:

class Program

end

This example uses the brackets on a new line.

As said before the next thing a default pandah program has is a main function. A main function looks like this:

function Main <- void

end

The first thing that should stand out is the use of the "function" keyword. After the function comes the identifier. This identifier is used to locate the function. Next comes the assignment operator. When used on a function this operator tells the function what parameters its getting. The "Main" function doesn’t get any arguments by default so we give it void (nothing). When put together the program should now look like this:

class Program
	function Main <- void;

	end
end

Now that we've got the basic setup of a Pandah program we can start the actual programming part! The easiest way to print a string in Pandah is by using the "print" statement This is how the print statement works:

print message

as you can see we can print out "Hello World" by doing

print "Hello World"

like other languages text is written between double apostrophe's We can now create our final Hello World program:

class Program
	function Main <- void;
		print "Hello World"
	end
end

when interpreted you should get the output: Hello World!

Chapter 2: Fundamentals

Statements Everything you do in pandah is started with a statement keyword. These statement keywords are:

let
exec
init
print
input
(more to come)

Let keyword The let keyword is used to change the value of a variable and is used like this:

let VARIABLE <- VALUE;

VARIABLE is the identifier of the variable you want to change the value of VALUE is the new value that should be stored in the variable The value can consist of more than just one value (e.g. let var <- 5 + 5; which will result in 10)

Exec keyword The exec keyword is used when one wants to execute a function and is used like this:

exec FUNCTION();

FUNCTION is the identifier of the function you want to call Function parameters are to be put in between the braces

Alternatively, you could call a function on an instance you just created (See: Init keyword) Doing this will execute the function in that instance and looks like this:

exec INSTANCE.FUNCTION()

INSTANCE is the instance you created

Init keyword The init keyword is used to create another instance of a class and is used like this:

init INSTANCE <- CLASS;

INSTANCE is the identifier of the instance you want to make. CLASS is the class of which you want to make an instance. Instances cannot be made from static class and it will throw an error if you attempt to do so.

Print keyword The print keyword is used to print something to the screen and is used like this:

print TOPRINT

TOPRINT is the thing you want to print.

Input keyword The input keyword is the basic way of getting input from the use in Pandah. Just like C#'s Console.Readline it reads the input until it receives a newline. The input keyword is used like this:

input IDENTIFIER

the identifier is the variable you want to store the input in

TODO: think of more keywords
