Use a visitor to wrap non-namespaced code in an empty namespace.

[rjkip]

I found that some of the classes were outputted without a namespace, causing a PHP Fatal error: No code may exist outside of namespace {}. A quick fix was implemented in #7, but this ignores files with the character sequence namespace, regardless of its position. It may appear in a comment, for example.

I've implemented a node visitor that ensures all code is wrapped in an empty/root namespace. I didn't feel it was necessary to make this configurable, so I did not implement an additional command line option.

The bug still exist, @mtdowling do you have any comments about it? I mean bug in the previous version without this pull request applied. I have not checked the pull request yet. So it would be good to fix it.

[hinikato]

For tests you can use the https://github.com/doctrine/doctrine1/blob/master/lib/Doctrine/Configurable.php class - it has the '$namespace ' string.

The pull request works partially, try run it for Zend Framework 1, it creates separated blocks for each require_once, it is not a big problem but it becomes a problem when there are use statements in the file (to find a use case use other than ZF 1 files).

[rjkip]

Hmm, I'll look into those separate blocks.

[hinikato]

I would like to clarify a situation. It seems like the error occurs for the following case: a file defines one or more classes without namespace (Iike in ZF 1) but uses 'use' statements, for example:

<?php
use My\Other\Class;

class Foo {}

Is this still an issue?

Ping @rjkip and @hinikato.

[rjkip]

Woo, that's a long time ago. Will see if I have time in a couple of hours. I'll get back to you.

[GrahamCampbell]

Ping @rjkip.

Fixed by #49.
