What do all those files mean?
|
|
=============================
|
|
|
|
* `zend_language_parser.y`: Original PHP grammer this parser is based on
|
|
* `zend_language_parser.phpy`: PHP grammer written in a pseudo language
|
|
* `analyze.php`: Analyzes the `.phpy`-grammer and outputs some info about it
|
|
* `rebuildParser.php`: Preprocesses the `.phpy`-grammar and builds the parser using `kmyacc`
|
|
* `kmyacc.php.parser`: A `kmyacc` parser prototype file for PHP
|
|
|
|
.phpy pseudo language
|
|
=====================
|
|
|
|
The `.phpy` file is a normal grammer in `kmyacc` (`yacc`) style, with some transformations
|
|
applied to it:
|
|
|
|
* Nodes are created using the syntax `Name[subNode1: ..., subNode2: ...]`. This is transformed into
|
|
`new PHPParser_Node_Name(array('subNode1' => ..., 'subNode2' => ...), $line, $docComment)`
|
|
* `Name::abc` is transformed to `PHPParser_Node_Name::abc`
|
|
* Some function-like constructs are resolved (see `rebuildParser.php` for a list)
|
|
|
|
Building the parser
|
|
===================
|
|
|
|
In order to rebuild the parser, you need [moriyoshi's fork of kmyacc](https://github.com/moriyoshi/kmyacc-forked).
|
|
After you compiled/installed it, run the `rebuildParser.php` file. |
