Racket-lang: A Programmable Programming Language
You must have read our coverage on programming language and its development. If not, I would recommend you to go through it once. There are very interesting articles on Top Programming Languages on GitHub, Highest Paying Programming Languages and many more. This article is about a new programming language called Racket-lang which is gaining a lot of attention of programmers these day.
What is Racket-lang:
Racket is a descendant of Lisp, a programming language renowned for its elegance, power, and challenging learning curve. But while Racket retains the functional goodness of Lisp, it was designed with beginning programmers in mind. It goes beyond Lisp and Scheme with dialects that support objects, types, laziness, and more. Racket enables programmers to link components written in different dialects, and it empowers programmers to create new,project-specific dialects. Racket’s libraries support applications from web servers and databases to GUIs and charts.
A glimpse of Racket-lang:
Getting started with Racket-lang is pretty easy unlike lisp which requires a substantial amount of knowledge before even you write your first hello world program. Below is a small example to get you started with Racket-lang –
;;;hello world in Racket #lang racket "Hello, World!"
;;;This program, taken from the Racket website, draws a Sierpinski triangle, nested to depth 8.
#lang racket
(require 2htdp/image)
(let sierpinski ([n 8])
(if (zero? n)
(triangle 2 'solid 'red)
(let ([t (sierpinski (- n 1))])
(freeze (above t (beside t t)))))) 
IDE for Racket-lang:
Racket-lang has a plethora of tools and among those DrRacket is a Racket’s graphical environment for developing programs. You can get it from here. Other useful tools are –
- Futures Visualizer
- Optimization Coach
- PLaneT: Automatic Package Distribution
- Racklog: Prolog-Style Logic Programming
- RackUnit: Unit Testing
- Redex: Practical Semantics Engineering
- Scribble as Preprocessor
- Slideshow: Figure and Presentation Tools
Learning Racket is easy and the community is very active so you get your doubts clear easily. Also, the documentation of Racket is vast and complete and help you understand every bit of language.
