Tank

It's Dynamic type Object oriented and scripting language written in Java

Features

• import native modules
• Classes
• Array data structure with dynamic types
• Single Inheritance like Java
• this keyword
• Methods
• Functions
• Function Extenson
• Local functions
• Native Functions
• Ternary (X ? Y : Z) and Elvis (X ? Y) Operators
• If condition
• While loop
• Do While Loop
• Repeat block like Kotlin
• Scope and Block
• super, this keywords for oop
• Break and Continue keyword for loops
• Logical operators AND, OR, XOR
• Bitwise operators <<, >>, >>>
• Function can take other Function as Parameter
• Runtime error
• Semantic analysis
• Arity Similar to Python that throw error if developer pass less or more than function arguments
• Create custom prefix operators
• Create custom infix Operators

Arrays

Function Extension.

Parse Json.

Make Network Request.

Get system information.

module tank.system;

print("Current os name is : " + osName() + "\n");

print("JDK Path : " + osEnvVar("JAVA_HOME") + "\n");

print("OS Arch : " + osArch() + "\n");

Test statement to show request result in the runtime.

func sum(x, y) {
   return x + y;
}

test ("test sum function") {
   return sum(1, 1) == 2;
}

Custom infix Operator function

infix func sum(x, y) {
   return x + y;
}

var sumResult = 10 sum 20;     // will be 30
var sumResult2 = sum(10, 20);  // will be 30

Custom prefix Operator function

prefix func multiByTen(x) {
   return x * 10;
}

var result = multiByTen 10;    // will be 100
var result2 = multiByTen(10);  // will be 100

Example of Infix and prefix functions

prefix func say(message) {
   print(message + "\n");
}

infix func to(left, right) {
   return left + " " + right;
}

// Option 1
say "Hello" to "Amr";

// Option 2
say(to("Hello", "Amr"));

Tools:

Code Style Check for Tank code to check if your code style is match your check configuration

• Check class name and super class name.
• Check method name and parameters.
• Check function name and parameters.
• Check function extension name and parameters.
• Check variables name.
• Check test block tag.
• Check if constants folding is possible.

For Example.
