oktolang - A silly little programming language

What is Okto?

Okto is an interpreted programming language written in C++. It's a strongly typed language which tells you exactly where you messed up if there's an error. Both a REPL and file input are supported.

Why is Okto?

No reason.

Maybe one day the NodeJS community will find it and obsess over it in it's unoptimisedness. But that remains to be seen.

How do I Okto?

First, download the source code and your favourite C++ compiler. Next, clone the repo (git clone https://git.maxwellj.xyz/max/okto) and CD into it. Compile the code (if the GCC is your poison, g++ src/okto -o okto) and run the binary.

Now we can start writing our code!

The Basics of Okto

Syntax

Okto's syntax is still developing, and may change at any time. So if you update and your code breaks, check back here.

Functions usually work like this:

functionName arg1 arg2 arg3

A bit like Python 2 or shell.

Some built in functions include:

log: Log something to the console. Usage: log (variable, string, decimal, integer) Example: log "Hello, World!" type: Check the type of something. If it doesn't have a type, it's unknown. Usage: type (function, variable, string, decimal, integer, incrementor, modifier, operator, comparitor, equals) Example: type 432

Okto is strongly typed, which means we need to learn about all the different types in the language! At present there are three types in Okto: strings, integers and decimals. Defining variables uses a C/C++ like syntax.

Strings

Strings are a bunch of letters enclosed in double quotes, like "this".

Define a string in Okto with str myString = "Hello World!"

Integers

Integers are whole numbers, like 7.

Define an integer in Okto with int myInteger = 7

Decimals

Decimals are non-whole numbers, like 3.14159.

Define a decimal in Okto with dec myDecimal = 3.14159

Updating Variables

Right now only integers and decimals can be changed. I'll refer to these as numbers.

Increment numbers with myVariable ++ and decrement with myVariable --.

Add stuff together in number variables with myVariable = myOtherVariable + 7. You can also subtract, multiply and divide with -, * and / respectively. For now you can't math outside of variables as it's still a prototype feature.
