Aug 10, 2018 The language also facilitates declaration of user-defined classes and much more. I personally recommend this language to you as if you really wanted to get into hacking. The reason behind my statement is that these languages will teach you about the basic concept of coding and also provide an insight knowledge of how loops and conditional.

Facebook Engineer?

Unless you are specifically working on open source Hack code, you want Facebook's internal documentation instead for dev environment setup. If you're just looking to learn the Hack language itself, skip this Getting Started section.

Hack is built specifically for HHVM, a high performance runtime for your Hack applications, and reconciles the fast development cycle of a dynamically typed language with the discipline provided by static typing, while adding many features commonly found in other modern programming languages.

Overview

The prerequisites you need to write and execute Hack code are pretty straightforward:

  • The HHVM runtime
  • The Hack typechecker (included with HHVM packages/builds)
  • Optionally, a Hack-aware editor. We recommend Visual Studio Code withvscode-hack, and Vim with ALE also offers an excellent experience.

Your First Hack Program

Let's dive right in and create your first Hack program using the following, simple steps.

1. Install HHVM and the Typechecker

Check out the HHVM getting started guide on howto install HHVM.

After you install HHVM, the Hack typechecker will be available to you, so you can statically checkyour code before you run it. It is not a compiler; but rather, a super-fast code analyzer that triesto catch dynamic programming errors before code is run instead of during or after.

The typechecker is called hh_client and is available by default alongside HHVM in all officialpackages supported by the HHVM team. If you are using a community-contributed package, hh_clientis very likely available there too, but you should check with your package maintainer.

2. Setup for the Typechecker

Choose a directory where you want to store your Hack code. In this directory, run touch .hhconfig. Thiscreates an empty file that hh_client looks for as the root of your code to be typechecked. Inorder to properly analyze your code, the typechecker needs to do global analysis and be able to seeall of your code. This means that it assumes a global autoloader for any code under this root, andchecks all code recursively under this root together as one project.

3. Write your first Hack program

Using the editor of your choice (e.g., VSCode or vim), let's create a file called first.hack with the following code:

This guide assumes some knowledge of programming. Hack has a very similar look and feel to PHP, which inturn, supports a lot of syntax shared by C, C++, C#, Java, and JavaScript. Here are the key points to note about this example:

  • This code belongs to the unique, but arbitrary, namespace called HackGettingStartedMyFirstProgram.
  • The <<__EntryPoint>> annotation marks this function as the point where execution starts - there is nothing special about the function name main.
  • main is a function that has no parameters and, being void, returns no value. Furthermore, this functionis where the program will begin execution; that is, because of the <<__EntryPoint>> annotation, main is the entry-point function.
  • echo writes some text and a blank line to standard output.
  • printf also writes to standard output, but it provides format control, in this case, to right-justify the integer columns.
  • The for loop has variable $i go from -5 to +5, in steps of 1, and for each iteration, the valueof $i and that value squared are written out together on a separate line.

4. Run the Typechecker

If you are using Visual Studio Code with vscode-hack or Vim with ALE, you will be seeing typechecking information as you write the program. If you run the typechecker from the command line, the command is just:

You should see:

5. Run the code in HHVM

After you get your Hack program to typecheck clean with no errors, you can then run theprogram in HHVM, as follows:

Now, go forth and Hack away!
