PHP-Parser PSR-2 pretty printer

Unsurprisingly, a PSR-2 pretty printer for PHP-Parser.

Installation

Composer

Add the package to your composer.json requirements e.g.

"require": {
    "tcopestake/php-parser-psr-2-pretty-printer": "dev-release"
}

Usage

To use this pretty printer, instantiate PHPParserPSR2_Printer instead of (for example) PHPParser_PrettyPrinter_Default and use it as you would normally. e.g:

$printer = new PHPParserPSR2_Printer;

...

echo $printer->prettyPrint($stmts);

Features

Intentional changes that differ from the default pretty printer are:

• If more than one interface is implemented, each definition will go on a new line.
• Space between "use" and parameters in closure definitions.
• If more than two parameters are defined for a method, each definition goes on a new line.
• If more than two arguments are passed to a method, each argument goes on a new line.
• Optional method renaming. (see below)

Method renaming

By default, method names are considered volatile and are therefore not renamed. However, if you're feeling brave you can call setMethodsVolatile(false) to have the printer convert snake-cased method names to camel case. For example:

protected function do_something() {
    return 1 + 1;
}

function get_class_to_do_something() {
    return $this->do_something();
}

becomes:

protected function doSomething()
{
    return 1 + 1;
}

public function getClassToDoSomething()
{
    return $this->doSomething();
}

Example

Input:

class ABC extends \A implements \B, \C {
    public function a_method_name($awefwefwef, $ywefwefwefwefwef, $wwefwefwefwefwe) {
        $x = function() use($awefwefwef, $wwefwefwefwefwe)
        {
            if(1==1)
                return $ywefwefwefwefwef;
        };

   // do something

        echo $x;
    }

    function bxy(array $g)
    {
                // do something

        return $this->a_method_name($g, $f, $x);
    }

    function z(array $g)
    {
        foreach($y as $n)
        {

        }
    }
}

Output:

class ABC extends \A implements
    \B,
    \C
{
    public function aMethodName(
        $awefwefwef,
        $ywefwefwefwefwef,
        $wwefwefwefwefwe
    ) {
        $x = function () use ($awefwefwef, $wwefwefwefwefwe) {
            if (1 == 1) {
                return $ywefwefwefwefwef;
            }
        };
        // do something
        echo $x;
    }

    public function bxy(array $g)
    {
        // do something
        return $this->aMethodName(
            $g,
            $f,
            $x
        );
    }

    public function z(array $g)
    {
        foreach ($y as $n) {

        }
    }

}
