Ankara Programming Language

Overview

Ankara is a programming language designed to offer unique features such as watch, block-level-return, and a unified syntax for both arrays and objects. Simplify your code and enhance readability with Ankara's straightforward syntax and features.

⚠️ This project is experimental and was created to try out new syntax possibilities. It may contain several bugs, so use it at your own risk.

Run Code

We have a sample code in ./sample/*.ank. You can run it with the following commands.

git clone https://github.com/islandryu/Ankara.git
cargo build --release
# run ./sample/watch.ank
./run_code.sh watch

or

Download from release

example windows

1. Download and unzip from https://github.com/islandryu/Ankara/releases/download/v0.0.1/Ankara_v0.0.1_x86_64-pc-windows-gnu.zip
2. Unzip Ankara_v0.0.1_x86_64-pc-windows-gnu.zip
3. Run command like Ankara.exe sample.ank

// sample.ank
let add = fn (a, b) {
  a + b
};

print(add(5,5));

let multiple = fn (a) {
　　// This expression has no semi-colon, so the block level return is applied after evaluation.
　　// In other words, this "for expression" returns the value of the first array of a multiplied by two.
    for(val in a) {
        val * 2
    }
};

print(multiple([1, 2, 3]));

let precedence = 1 + 2 * 3 + (4 + 5) / 3 - 10;

print(precedence)

Features

Watch

Automatically update a variable's value when its dependencies change.

Block-Level Return

Return values directly from a block, making the code more readable and expressive.

Unified Array and Object Syntax

Manipulate both arrays and objects using a consistent and unified syntax.

Sample Code

Basic Array Iteration

let array = [1, 2, 3];

for(i in array) {
　　// 1 2 3
    print(i);
};

Working with Objects

let obj = [bar: 1, baz: 2];

// 1
print(obj["bar"]);
// 2
print(obj["baz"]);

Unified Object and Array

let objAndArray = [1, bar: 1, baz: 2];

for(i in objAndArray) {
    // 1 1 2
    print(i);
};

// 1
print(obj["bar"]);
// 2
print(obj["baz"]);

Block-Level Return

If there is no semicolon at the end of the line, the value is returned at block level as block level return

let func1 = fn () {
    let val = {
        1 + 1
    };
    return val;
};

// 2
print(func1());

Watch Variables

let x = 1;
let y = 2;

watch added = {
    x + y
};

// 3
print(added);

x = 100;

// 102
print(added);
