elys

scripting language

Why Elys? 🤔

Elys is a lightweight scripting language written in Nim, designed to seamlessly integrate into various applications.

Thanks to its compact implementation, Elys can be embedded into Minecraft mods, web applications, native apps, mobile applications, and even devices like smart refrigerators.

With its simple syntax, Elys is an excellent choice for rapid prototyping and building extensible systems.

It provides easy interaction with the host application and straightforward handling of tasks such as data management, interface control, and process automation.

API

If you want to use elys in your project, then you just need to install it using nimble and use it as follows:

nimble install https://github.com/HapticX/elys

import elys

discard elys.exec("print(1)")

Hello, world! 👋

Here's hello world program written in Elys:

print('Hello, world!')

Variables 🧩

Elys supports two types of variables - var and const.

var is mutable variable. const is immutable variable

Example

var x = 10
const y = 20

x = 20  # success
y = 10  # error

If Statements ❓

if (2 + 2 * 2 == 8) {  # Order of operations as in math
  print('nope, 2 + 2 * 2 is 6 :(')
} elif (2 + 2 * 2 == 6) {
  print('yeap, 2 + 2 * 2 is 6!')
} else {
  print('???')
}

You can also use if statements as an expression to obtain a result for a variable:

var x = if (false) {
  0
} elif (false) {
  1
} else {
  2
}
print x  # will be 2

Cycles 🔄

Elys provides for and while cycles:

for i in 0..<10 {
  print i  # will shows numbers from 0 to 9
}

var x = 0
while x < 10 {
  x++
}
print x  # will be 10
