phply is a parser for the PHP programming language written using PLY, a Lex/YACC-style parser generator toolkit for Python.
Good question. Because I'm crazy. Because it seemed possible.
Things I'm interested in doing with it:
- Converting PHP code to Python
- Running PHP templates in a Python environment
- Learning more about parsing "industrial" languages, warts and all
- phply -> PHP PLY
- phply -> PHP Hypertext Preprocessor Python Lex YACC
- phply -> PHP Hypertext Preprocessor Hypertext Preprocessor Python Lex Yet Another Compiler Compiler
- (... to be completed ...)
If you're conservative, it's pronounced "pee aich ply". If you're liberal, it's "fiply". And if you're anarchist, pronounce it however you want. Who am I to tell you what to do?
- Lexer matching the standard PHP lexer token-for-token
- Parser and abstract syntax tree for most of the PHP grammar
- Script to convert PHP source to JSON-based ASTs
- Script to convert PHP source to Jinja2 source (experimental)
Some things can't be parsed yet. They are getting fewer by the day, but there is still a fair amount of work to do:
- Binary string literals and casts
- Labels and goto
- Some other stuff, probably
See the AUTHORS file.
- Lexer test: python phply/phplex.py
- Parser test: python phply/phpparse.py
- JSON dump: cd tools; python php2json.py < input.php > output.json
- Jinja2 conversion: cd tools; python php2jinja.py < input.php > output.html
- Fork me on GitHub and start hacking :)
