# Tusk
[](https://travis-ci.org/bonndan/tusk)
[](https://gemnasium.com/github.com/bonndan/tusk)
[](https://php.net/)
Tusk is an experimental transpiler to convert PHP sources into http://groovy-lang.org/.
In order to accomplish this it creates an AST using https://github.com/nikic/PHP-Parser and then attempts to write
the nodes in Groovy syntax.
## Goal
Tusk is meant as support tool to port PHP projects to Groovy/Java with low efforts. It does not
aim at full-auto magic conversion, but aims to create mostly error-free Groovy sources
enriched with hints. Then with a decent IDE missing things can be quickly resolved.
## Features
PHP source:
Groovy outuput
* converts php expressions into valid Groovy
* handles incompatibilites as far as possible (e.g. "break 2")
* evaluates type information gathered by PHP-Parser and tries to find equivalents
* uses DocBlock type information where available
* convert some builtin php functions with Groovy equivalents (e.g. isset)
* add automatic custom imports
* add on demand imports of non-resolvable classes via mapping
## Configuration
```php
require './vendor/autoload.php';
ini_set('xdebug.max_nesting_level', 3000);
$t = new \Tusk\Tusk(Tusk\Configuration::create(
[
'source' => dirname(__DIR__) . '/mylegacyproject',
'target' => dirname(__DIR__) . '/myshinynewgroovyproject',
'namespaces' => [
'src' => '__AUTO__',
//folder actions go into package Shiny.Actions
'actions' => 'Shiny.Actions',
//include files go into package Shiny.Common
'include' => 'Shiny.Common',
],
//these folders are copied into the resources dir
'resources' => [
'templates' => 'templates',
'languages' => 'languages',
],
//the docs folder is copied into a new dir documentation
'other' => [
'docs' => 'documentation'
],
//if these class names appear, import statements are added
'onDemandImport' => [
'Controller' => 'Shiny.Controller',
'DatabaseInterface' => 'Shiny.DatabaseInterface',
'Event' => 'Shiny.Event',
'Base' => 'Shiny.Base',
'Pagination' => 'Shiny.Pagination',
],
//
'replaceNames' => [
//use function > import static
'between' => 'Shiny.functions.between',
'valNum' => 'Shiny.functions.valNum',
//simple name replacement, here a constant
'DIR_SEPERATOR' => "'/'",
]
]
));
$t->run();
```
## Challenges
* arrays. It's hard to find out whether a PHP array can be translated into a Collection, Array or Map or won't work.
* PHP built-in functions need to be rewritten in Java or Groovy or replaced with equivalents.
* garbage like "goto"
* fancy stuff like yield, destructors, magic methods and constants
* casting precedence of objects (non-scalar) not regarded yet
* use eachwithindex if loop does not contain: break, continue, return
* prevent useless casting: if ((int) id > 0) where id is already int
* simplify boolean comparison: "false==" or "true=="
