About The Project

SrcLang or Source Programming Language is an easy to learn, dynamically typed bytecode Programming Language for platform Independent Application Development.

Here's why:

• Write once run everywhere
• Faster, efficient and lightweight
• Easy to learn, you can get use to it within a weekend.

Getting Started

SrcLang uses only system provided libraries and hence no special setup is required other than CMake and C++ Compiler to build and run SrcLang.

Usage

You can either compile the code from source or use the continuous release build from GitHub Release

Basics

# Supported DataType

# Boolean
true false

# Number
10 10.02 10_00_000.0_10

# String
"Supported Multiline
String by Default"

# List
[10, true, "Hey", fun () { return 0; }, {a: 10, b: 20}];

# Map
{
  a: 10,
  b: "20",
  c: [20, 40]
}

# Closures
let adder = fun (p) {
  return fun (a, b) {
    return a + b + p;
  };
};
let p_adder = adder(2);

println (p_adder(20, 30));


# Error
error("This is a error");

# Type
let str_type = type("string");

# Nil
nil


# Variable declaration

let x = 10;

x := 10; # Declare variable of not already defined else reassign new value

# Condition

# Condition support multiple statements
if result := false; not result {
  println ("Not Result");
} else {
  println ("Result");
}

# Loops

for true {
  println ("infinite");
}

for a in [10, 20, 30, 40] {
  println (a);
}

for a in range(0, 10, 2) {
  println (a);
}

# Function

# Functions in SrcLang are First class Citizens
# and can be assigned as normal values

let adder = fun (pre) {
  return fun (a, b) {
    return a + b + pre;
  };
};

let th_adder = adder(10);
println (th_adder(20, 30));

# Error handling
if ok := someFun(10); not ok {
  println ("Error");
};

# Object Oriented

let Complex = fun (real, img) {
  self := { real: real, img: img};
  
  self.__type__ = fun () {
    return "<complex>;
  };
  
  self.__str__ = fun () {
    return str(self.real) + " i" + str(self.img);
  };
  
  self.Add = fun (other) {
    return Complex(self.real + other.real, self.img + other.img);
  };
};

let complex = Complex(10, 20);

println (complex);

# Resource Management via defer

if let file = open("hello.txt"); not file {
  ...
}
defer { file.Close(); };


# Builtins

# To get length of elements
len("Hello World");

# Append and Pop value in list
let arr = [10, 20];
arr = append(arr, 30);

arr = pop(arr);

# Range to generate a list of values
# range(end);
# range(start, end);
# range(start, end, inc);

let arr = range(10);
arr = range(2, 10);
arr = range(5, 10, 2);

# Lazy evaluate SrcLang code
let result = eval("range(10);");


# Safely call SrcLang function in sandbox
let result = call(adder, 10, 20);

# Open() to create and edit file

let file = open("hello.txt");
defer { file.Close() };
file.Write("Hello World");

# Exec() to execute system calls
let status = exec("dir", fun (out) {
  print(out);
});

# Socket to create socket

let sock = socket("tcp4");

sock.Bind("0.0.0.0:8000");

sock.File.Write("Hello World");
