GFY

GFY (can't say what the acronym means) is a simple interpreted language designed for basic scripting tasks. It provides basic functionality for variable manipulation, conditional statements, and control flow.

Installation

To use GFY, you need to have Node.js installed on your system. You can install GFY by cloning this repository:

git clone https://github.com/EtanoloYT/gfy.git
cd gfy

Then, install the required npm packages:

npm install

Usage

Once installed, you can use GFY to interpret and execute scripts written in its syntax. To execute a GFY script, use the following command:

node . <filename>

Replace <filename> with the path to your GFY script.

Syntax

GFY supports the following syntax:

Variables

• set <variable> <value>: Assigns a value to a variable.
• print <variable>: Prints the value of a variable.

Arithmetic Operations

• add <variable> <value>: Adds a value to a variable.
• sub <variable> <value>: Subtracts a value from a variable.
• mul <variable> <value>: Multiplies a variable by a value.
• div <variable> <value>: Divides a variable by a value.
• mod <variable> <value>: Computes the modulus of a variable with a value.

Control Flow

• equals <variable> <variable>:: Checks if two variables are equal.
• greater <variable> <variable>: Checks if the first variable is greater than the second.
• less <variable> <variable>: Checks if the first variable is less than the second.
• Example:

  set x 10
  set y 5
  equals x y:
  print "x=y"
  end

Function Definitions

• define <name>(<parameters>):: Defines a function with the given name and parameters.
• end: Ends the function definition.
• <name> <arguments>: Calls a function with the given name and arguments.
• Callables: special functions that can be called as if they were variables. They can be defined using square brackets.

• Example:

  define square(x):
  mul x x
  end
  
  set y 5
  square y
  print y

Modules

• £import <folder>/<module>: Imports a module.

• Example:

  £import Modules/std
  
  define forBody():
  print i
  end
  
  set i 0
  set stop 10
  
  for i stop forBody

Example

Here's an example of a simple GFY script:

set x 10
set y 5
add x y
print x

// x is now 15

This script sets variables x and y to 10 and 5 respectively, adds them together and prints the new value of x.

Supported Extensions

GFY supports the following file extensions:

• .gfy: GFY script files
