The Swas programming language

This is a language that was made for fun.

Installation

Step 0: Make sure you have python installed
Step 1. Clone this repo or download it as a zip
Step 2. Run pip install -r requirements.txt

This is all that you need to do to start writing in swas lang.

Running

python -m swas [filename]

The filename is optional, if no filename is provided it will run the shell.

Getting Started

Hello World

output "Hello, World!"

Variables

Variables are containers for storing data.

Creating Variables

Swas has no command for declaring a variable.

A variable is created the moment you first assign a value to it.

x => 5
y => "Mark"

Using Variables

To use the variables, simply reference them

output x
output y

Case Sensitive

Note: Variables names are case sensitive i.e. a => 5 is not the same as A => 5

Operators

Operators are used to perform operations on variables and values.

Arithmetic Operators

Logical Operators

Join Operator ( & )

The Join Operator ( & ) lets you join 2 statements into 1.

Example

output "Hi" & output "Bye"

The Assignment Operator ( => )

The Assignment Operator ( => ) is used to assign a variable to a value.

If Else

An "if else statement" is written by using the if and else keywords.

Syntax

if condition => {
  statement 
}
else => {
  statement 
}

Note: The indentation isn't needed, it has been used here for readability

Example

name => input "Enter your name: " &
if name == "John" => {
  output "hi," + name 
}
else => {
  output "bye," + name 
}

While Do

With the while loop you can execute a set of statements as long as a condition is true.

Syntax

while condition 
do {
  statement
}

Note: The indentation isn't needed, it has been used here for readability

Example

start => 1 &
end => 10 &

while start != end
do {
  output start & inc start 
}
