Code formatter

[ichiriac]

Integrate https://github.com/glayzzle/php-unparser as external library in order to format back PHP code.

This library consume php-parser AST tree and builds back the PHP formatting with proper indentation. Can try here an old online version : https://chris-l.github.io/php-unparser/.

Actually supported options :

• indent : indentation char (2 or 4 spaces, one tab ...)
• dontUseWhitespaces : use optional white space between if, for... and the paranthesis
• shortArray : enable the short array syntax (supported only in PHP7)
• forceNamespaceBrackets : force every namespace to be with brackets (even if it's only one namespace by file - usefull to concatenate file)

As the formatting is based on AST, the simplest is to re-format all the file.

Note : Could be possible to format only a portion of code by scanning all the file, using offsets to identify the root node, and then pass it on the formatter - this way is hard to implement and with edge cases

---

ToDo :

• create a branch : as the maintainer of the original library does not merge or work on the library, fork it and publish a new npm library

• refactor options : put into options any kind of parameter (brackets on same line on function/class/other) ... etc ...

• create rulesets : using option pressets configure PSR1...,N/Zend/PEAR...

• declare a shortcut command like CTRL+MAJ+F

Could also include this topic : (Format Line on Type Provider https://github.com/HvyIndustries/crane/issues/214) - the formating would be based on the same configuration for space indentation.

Couldn't it be provided as a VS Code Document Formatter instead of a custom shortcut ?
