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:

dependencies:
  mysql:

    version: ~>0.16.0

Investors overreact to dramatic news stories (creating value opportunities in beaten-down stocks) and underreact to boring, consistent fundamental earnings data.

Before we dissect the PDF, we must understand the author. Robert Haugen was a Professor of Finance at the University of California, Irvine, and previously taught at Carnegie Mellon, University of Wisconsin–Madison, and Indiana University.

: Websites like Textbooks.com and eCampus.com , which sell the physical textbook, sometimes offer sample chapter PDFs to help customers make a purchase decision. These can be a valuable resource for reading key sections like the introduction or the chapter on the CAPM for free. robert haugen modern investment theorypdf

In an era dominated by algorithmic trading, high-frequency execution, and artificial intelligence, Haugen’s insights are more relevant than ever.

Robert Haugen’s work, particularly his influential text Modern Investment Theory , remains a cornerstone of financial literature. While many investors are familiar with traditional Modern Portfolio Theory (MPT) established by Harry Markowitz, Haugen expanded upon these concepts, providing a more comprehensive framework for understanding risk, return, and market efficiency. For those seeking the , it is crucial to first understand the core, groundbreaking concepts discussed within its pages.

Elara sat back, her heart thumping in the silent vault. She wasn't looking at a textbook. She was looking at a treasure map. And the "They" in Haugen's note weren't a conspiracy of bankers. They were the architects of the new financial order—the ones who had made volatility illegal, risk a sin, and true insight a relic. For those interested in exploring Robert Haugen's work
