Domain-Specific Languages: Design and Implementation

General-Purpose and Domain-Specific Programming Languages

Explore the characteristics and uses of general-purpose languages like Java and Python compared to domain-specific languages tailored for specific tasks. Learn how DSLs improve productivity, code quality, and accessibility for non-programmers, while noting the complementary relationship between GPLs and DSLs. This lesson establishes the foundational concepts needed for designing and implementing DSLs.

We'll cover the following...

General-purpose programming languages (GPLs)

General-purpose programming languages are designed for a wide variety of tasks and applications. Examples include C, C++, Java, Python, and JavaScript. These languages are often used for building desktop and mobile applications, web development, game development, and scientific computing.

GPLs

They provide a wide range of features and libraries that make it easy to perform various tasks, and constitute large communities of developers who have created and contributed to various libraries and frameworks.

Following are the Hello World programs in some of the famous GPLs:

#include <iostream>
using namespace std;
int main() {
  // your code goes here
  cout << "Hello World";
  return 0;
}
