Create prototype about php-scoper HOT 7 CLOSED

Alternatively, nikic/php-ast (or sgolemon/astkit) could be used as the backend instead of nikic/PHP-Parser. That would require PHP 7 to work but would be future-proof.

Accessing the file position is possible, see https://github.com/nikic/PHP-Parser/blob/master/doc/component/Lexer.markdown#lexer-options. Assuming version 2 of the library, you need to create the parser using

$parser = (new ParserFactory)->create(ParserFactory::PREFER_PHP7, new Lexer([
    'usedAttributes' => [
         'docComment', 'startLine', 'endLine', 'startFilePos', 'endFilePos'
    ],
]));

and then access the position using $node->getAttribute('startFilePos') etc.

I combine this with a class that queues up modifications based on original offsets and then applies them all at once. (Doing it on the fly is a PITA because you need to track offset changes through the file).

@sebastianbergmann Can those tools be used for PHP 5 source code?

Hi,

@webmozart I'd love to give it a try, currently working on a first implementation. Can we agree to use the version 2 of nikic/PHP-Parser, even if it's still in alpha ?

Thanks

@matthieuauger sure, whatever you think is best :)
