“Corescript is a bare-bones minimalist high-level
programming language designed to be extremely simple
and easy to hack.”
Corescript is not a flexible production language. It is a learning and
prototyping tool. It is not meant for advanced projects. Instead, it is
designed for simplicity, minimalism, and hackability.
Now that we have that out of the way, welcome to the official
Corescript programming guide.
To start off, let’s look at something very simple.
This is the classic “Hello, World” program.
print Hello, World!
Pretty straightforward, right? Good, let’s move on to the next example.
Variables can simply be declared by using:
var name = John
You must use a space between the equal sign, or the code will
not parse. And besides, it is easier to read that way.
To set a variable, use the set command.
set name = John Doe
Now that we have our cool variable, what do we do with it?
Well, you can’t eat it, nor can you use it to visit Mars, so
let’s try to print it to the screen.
print Hello, [name]!
Using parenthesis around variables isn’t only used in print, but
it can also be used in other commands that require strings.
var name = John
input question = How are you, [name]?
print Cool, goodbye [name].
In Corescript, anything between parenthesis will try to be parsed.
If the parsing does not succeed, then no nothing will be changed.
print [This is not a variable.]
Output: (This is not a variable)
Now that we have a few basic commands down, let’s use them to make another
example.
input name = What's your name?
print Hello, [name]!
This will ask for input, and greet the user once they have done so.
Sometimes you want to do something over and over again, like
annoying somebody until they give in. We do this in programming too.
:top
print This is repeated forever
goto top
In that example, we declare a label by using a : and putting
our label text after it. Then we put in our code, and when finished, tell it
to goto to the place where :top was called, and thus the cycle continues.
In the web editor, type “slow” into the terminal to turn on slowmode. This
will allow loop to work without crashing your page.
In programming, you will at one point need to use math.
Whether it is adding +1, or calculating the chances you will win
the lottery, programming would be useless without it.
var a = 12
set a = [add a 48]
print [a]
This should print 60. Pretty basic. There is more than just adding in Corescript
of course. These are the math functions available:
print [rand 1 10]Their purpose should all be pretty self-explainable.
len stringchar 1 variableThere are some other commands in Corescript I didn’t dedicate
a section to. The first one being return.
It is used with labels.
return goes back to the last time the label was used.
This excludes when the label was defined. An example explains this best.
goto hello
stop
:hello
print Hello!
return hello
When goto hello is called, it runs print hello, and since return was
last used on goto hello, it moves back to that line.
This is not an essential command, but it can be used to avoid this:
goto hello
:helloBack
stop
:hello
print Hello!
return helloBack
If statements are essential in programming.
If you want to check if variable name is “Jimmy”,
then you can do this:
var name = Jimmy
if name = Jimmy:enter
print You are not Jimmy...
stop
:enter
print Welcome, Jimmy.
In this example, if name is “Jimmy”, then goto “enter”.
If it is not “Jimmy”, then nothing will happen, and it will
resume to the next line as if nothing happened.
Lets say we want to try and be lucky, and see if our luck
can get 1 in a million. We will use the rand math function for this.
var luckyNumber = 32392
var guess = [rand 1 1000000]
if guess = [luckyNumber]:correct
print We did not get the lucky number :(
stop
:correct
print We did it! We got [guess]!
