A language for humans and computers

Examples

Crystal is a general-purpose, object-oriented programming language. With syntax inspired by Ruby, it’s a compiled language with static type-checking. Types are resolved by an advanced type inference algorithm.

# A very basic HTTP server
require "http/server"

server = HTTP::Server.new do |context|
  context.response.content_type = "text/plain"
  context.response.print "Hello world, got #{context.request.path}!"
end

address = server.bind_tcp(8080)
puts "Listening on http://#{address}"

# This call blocks until the process is terminated
server.listen

Batteries included

Crystal’s standard library comes with a whole range of libraries that let you start working on your project right away.

require "http/client"
require "json"

response = HTTP::Client.get("https://crystal-lang.org/api/versions.json")
json = JSON.parse(response.body)
version = json["versions"].as_a.find! { |entry| entry["released"]? != false }["name"]

puts "Latest Crystal version: #{version || "Unknown"}"

Type system

The compiler catches type errors early. Avoids null pointer exceptions at runtime.

The code is still clean and feels like a dynamic language.

def add(a, b)
  a + b
end

add 1, 2         # => 3
add "foo", "bar" # => "foobar"

Flow typing

The compiler tracks the type of variables at each point, and restricts types according to conditions.

loop do
  case message = gets # type is `String | Nil`
  when Nil
    break
  when ""
    puts "Please enter a message"
  else
    # In this branch, `message` cannot be `Nil` so we can safely call `String#upcase`
    puts message.upcase
  end
end

Concurrency Model

Crystal uses green threads, called fibers, to achieve concurrency. Fibers communicate with each other via channels without having to turn to shared memory or locks (CSP).

channel = Channel(Int32).new

3.times do |i|
  spawn do
    3.times do |j|
      sleep rand(100).milliseconds # add non-determinism for fun
      channel.send 10 * (i + 1) + j
    end
  end
end

9.times do
  puts channel.receive
end

C-bindings

Bindings for C libraries makes it easy to use existing tools. Crystal calls lib functions natively without any runtime overhead.

No need to implement the entire program in Crystal when there are already good libraries for some jobs.

# Define the lib bindings and link info:
@[Link("m")]
lib LibM
  fun pow(x : LibC::Double, y : LibC::Double) : LibC::Double
end

# Call a C function like a Crystal method:
puts LibM.pow(2.0, 4.0) # => 16.0

Macros

Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection, to types inspection and running arbitrary external programs.

macro upcase_getter(name)
  def {{ name.id }}
    @{{ name.id }}.upcase
  end
end

class Person
  upcase_getter name

  def initialize(@name : String)
  end
end

person = Person.new "John"
person.name # => "JOHN"

Dependencies

Crystal libraries are packed with Shards, a distributed dependency manager without a centralised repository.

It reads dependencies defined in shard.yml and fetches the source code from their repositories.

name: hello-world
version: 1.0.0
license: Apache-2.0

authors:
- Crys <crystal@manas.tech>

dependencies:

Okay, let's tackle this query. The user wants me to rephrase every term in the given text using three variants each, formatted as spintax like w1. They specified no changes to proper nouns. Hmm, first, I need to parse the original text carefully.

Let me start with the first paragraph. Take "vast" → immense. "Ever-expanding" → always broadening. "World" → domain. "Web series" → digital programs. Each replacement should be in the specified format with three synonyms separated by | within . Aah Se Aaha Tak Part 01 2024 Ullu www.moviespap...

Double-checking the replacements to make sure they are appropriate and the sentence still makes sense. Also, confirm that each instance has three options. Once done, reconstruct the entire text with the replacements in the correct format. Avoid any markdown, just plain text. Alright, that should cover it. Okay, let's tackle this query

I have to be careful with parts of speech. If the word is a noun, the synonyms should be nouns too. For example, "web series" could be "online shows," "streaming series," or "digital programs." But proper nouns like "Ullu" stay as is. Hmm, first, I need to parse the original text carefully

Unique plot: The show’s narrative is engaging, relatable, and full of surprises. Exceptional performances: The cast delivers impressive performances that make the characters feel authentic. High visual appeal: The show’s production values are superb, making for an enjoyable viewing experience.

Next, moving to the plot twists section: "intricate plot twists and character developments." "Intricate" can be "complicated," "complex," "elaborate." "Plot twists" might be "unexpected turns," "narrative surprises," "plot developments." "Character developments" could be "character growth," "personal evolution," "role progression."

I'm also careful with hyphenated words. For example, "ever-expanding" is a hyphenated adjective, so its synonyms should also be hyphenated if needed. However, the user might not want hyphens; perhaps they just need the synonyms. For instance, "ever-expanding" could have synonyms like "constantly growing" (two words) instead of keeping it as a single hyphenated word. But the original text has "ever-expanding," so perhaps the synonyms should be hyphenated as well if possible.
