Let's start with writing a sample program of printing cubes of numbers. eg:
Using the editor of your choice (e.g., VSCode or vim), let's create a file called
first.hack with the following code:
<<__entrypoint>>
function main(): void {
echo "Welcome to Hack! \n\nTutorial by Anwar Faiz\n\n";
\printf("Table of Cubes\n" .
"----------------\n");
for ($i = -5; $i <= 5; ++$i) {
\printf(" %2d %2d \n", $i, $i * $i * $i);
}
\printf("----------------\n");
exit(0);
}
To see the result of Typechecking:
$ hh_client first.hack
You should see:
No errors!
* Note that however, you might get following error - Error: /Users/mfaiz/ECPCP/hhvm-hack/first.hack is not a directory
But that is other issue. i will explain in next post.
To run the program on client side:
$hhvm first.hack
You will get following as result.
By the way by now I am already feeling like using Node like application for PHP. This is looking cool. Hurray!
Take care readers. And pour in your thoughts :)
