php-to-zephir's Introduction

Php to Zephir

Convert PHP to Zephir.

This project is builded on top of nikic/PHP-Parser

Install

composer require fezfez/php-to-zephir

How to use

vendor/bin/php-to-zephir phpToZephir:convert myDirToConvert

It converts all files recursivly to Zephir language.

Issue

If you find a bug, please report it by new issue (with tested php code to see error).

Fatal error :'(

If you find a fatal error during converting, add --debug and identify where the fatal error happen. Then open issue !

php-to-zephir's Issues

String Escape Character is not converted

I found this issue, It breaks compilation of zephir.
php code: protected $token_b = "/(\r\n)+|(\n|\r)+/";
Converted code:- protected token_b = "/( )+|( | )+/";
It converts \r\n as a new line non printable character and this breaks compilation.

Support for closures

Zephir implemented support for closures.
So now they can be used like in php instead of using separate pseudo-classes.

Clean up code

Support for Php7.1 and Php7.2

This library supports up to Php 7.0, thank you for this great job.
Do you think of adding support for Php 7.1 and 7.2 to this library soon?

Fix zephir version in composer.json

Implement PHPUnit_Extensions_PhptTestCase

Implement PHPUnit_Extensions_PhptTestCase in Phpunit test (phpt)

String indexing not converted

php

$name = "John";
if ($name[0] !== "J") {
    echo 'The name does not start with a capital J';
}

generated zep

if name[0] !== "J" {

fix

if substr(name, 0, 1) !== "J" {

Issues with the for loop and the unset statement

Hi there,
it seems that the library doesn't manage with the "for" loop and the "unset" statement.

This is my PHP code:

<?php
namespace Brainusers;
class ZephirTest {
    static public function hello() {
        $obj = array();
        for ($i=0; $i<1000; $i++) {
            $obj[] = new ZephirTest();
        }
        unset($obj);
    }
}

Output is:

namespace Brainusers;

class ZephirTest
{
    public static function hello() -> void
    {
        var obj, i;


        let obj =  [];
        for let i = 0; i < 1000; let i++ {
            let obj[] = new ZephirTest();
        }
        unset(obj);

    }

}

Trying to build:

$ zephir build
Zephir\ParseException: Syntax error in /php2zephir/brainusers/brainusers/zephirtest.zep on line 11

            for let i = 0; i < 1000; let i++ {
    --------------^

After changed to for i in range(0,1000) there is a problem with unset:

$ zephir build
Zephir\CompilerException: Cannot use expression type: variable in "unset" in /php2zephir/brainusers/brainusers/zephirtest.zep on line 14

            unset(obj);
    -----------------^

Printer "pExpr_List" does not exist

You guys did a really cool tool!

But I got some errors when I try to convert Doctrine 1.2.5 on PHP 7
https://github.com/doctrine/doctrine1

Please help!

first error:

I'm getting the above error when trying to convert a simple helper class. I guess this line causes the error:

return $stdout ?? NULL;

The Null coalescing operator is new since php 7

Add class for interacte with zephir compile

docblock hint applied without warning

  /**
   * @return bool
   */
  public function __construct() {

  }

zephir code:

public function __construct() -> bool

A constructor is not allowed to return any value in zephir. And this will crash. Maybe error or warning instead of just converting

Support PHP7

Add unit test

"and" not converted

in php

if !(is_scalar(v)) and !(is_array(v)) {

error

Zephir\ParseException: Syntax error in /home/flip101/zep/properties.zep on line 16

                    if !(is_scalar(v)) and !(is_array(v)) {
    -------------------------------------^

documentation: http://docs.zephir-lang.com/en/latest/operators.html#logical-operators

be aware that in php and and && do not have the same precedence, so be careful when converting them to zephir. https://secure.php.net/manual/en/language.operators.precedence.php

Ingore class that implements unknow interface

See zephir-lang/zephir#1062

Does not declare variable when used in preg_match function call

php

if (! preg_match('some regex here', $subject, $regs)) {

zephir

if !(preg_match("some regex here", subject, regs)) {

this will crash zephir because regs was not declared and initialized before.

fix

var regs;
let regs = null;
if !(preg_match("some regex here", subject, regs)) {

Add render interface

StringRender
FileRender

there alots of issues while compiling zephir from converted code

below log, when php to zephir

I have uploaded all code here [](https://github.com/surjit/zephir_ext)

please help me to sort the issues

Parsing Issues

This project is a wonderful find. Am working through my PHP source and keep hitting errors, as you are probably aware.

// error: matches not declared
preg_match($regex, $src, $matches);

// error: self not declared
method_exists(self, $foo);

// error: array immutable
return ["foo" => "bar"];

// error: parse exception
$return = ["foo" => "bar"];

Some of these may not be significant but reporting here in any case.

Abandoned project?

Hi, is this project abandoned?

I'm writing a framework and wanted to use this to convert core components to Zephir. But the code here is not compatible with PHP 5.4.16 (RHEL/CentOS default). If it's abandoned, can I fork and make it compatible?

Yeah, I know, 5.4 is old crap, but unfortunatelly, in Brazil, stupidit.. I meant, some idio... errr... Sysadmins only use RHEL official crap.

May I fork it for the Phalcony Rest Framework? I must convert some PHP to Zephir.

Fatal error:: Cannot use 'PhpParser\Node\Expr\Cast\Bool' as class name as it is reserved

When compiling I am getting this error when converting:

Fatal error: Cannot use 'PhpParser\Node\Expr\Cast\Bool' as class name as it is reserved in C:\Users\ganes\Downloads\php\php-to-c\php-to-c-extension\vendor\fezfez\php-to-zephir\src\PhpToZephir\Converter\Printer\Expr\Cast\BoolPrinter.php on line 16

I am working with arrays and using unset function. Its a simple iterator

Add CodeCollector interface

Closure numbering is not working correctly

php

<?php
namespace MySpace;

class TestClass {
    public function __construct() {
        $foo = function() {};
    }
}

output files:

testclass.zep

namespace MySpace;

class TestClass
{
    public function __construct() -> void
    {
        var foo;

        let foo =  new TestClass__constructClosureOne();
    }

}

testclass__constructclosurezero.zep

namespace MySpace;

class TestClass__constructClosureZero
{

    public function __construct()
    {

    }

    public function __invoke()
    {
    }
}

notice trying to instantiate class TestClass__constructClosureOne but class is TestClass__constructClosureZero --> One or Zero ??

Two bugs with static properties.

Hi.

I tested lastly php-to-zephir.
Cool tool, but I found two bugs with static properties.

static properties are declared as local variables.
name of property is not translated to zephir.

Example in php:

namespace Yii;

class Test {

    public static $x;

    public static function test1(){
    Test::$x = 1;
    }
}

result after conversion;

namespace Yii;

class Test
{
    public static x;
    public static function test1() -> void
    {
        var x;   // x already defined

        let Test::$x = 1;   // should be Test::x
    }

}

Assign dynamic expression to Array as second argument - doesn't work

Sample code with error:

$aggregation = [1,2,3];
$output[$position] = array_sum($aggregation) / count($aggregation);

Code without error

$aggregation = [1,2,3];
$variable = array_sum($aggregation) / count($aggregation);
$output[$position] = $variable;
