Any documentation?

Hi, where i can find any documentation for parser generator?

For now you can find generated documentation here http://peg-org.github.io/api/

I already can use this generator? Any examples?

Rigth now a doxygen xml parser/extractor is implemented to obtain symbols. On the generation side I started writing a Zend Engine Extension generator which generates wrappers for functions, variables, constants and some other minor stuff.

I use a CLI interface which isn't the official one at this repo https://github.com/peg-org/peg-custom for development purpose, it is mostly self documented, you can try peg-custom help The official CLI interface https://github.com/peg-org/peg-cli is going to be developed by some PHP-GTK developers, but for now they haven't found the time to keep working on it.

On my side, mostly what is missing is the generation of code that wraps C++ classes/structs which shouldn't be that hard to implement using the code that generates functions as a base example. Our idea is to easily generate wrappers for existing libraries like GTK, wxWidgets, QT, etc...

For now you can try the project by using peg-custom cli interface. The idea iis to first create the directory which will hold your extension

mkdir myextension
cd myextension

Then initialize that directory

peg-custom init

Afterwards extract symbols from a source like doxygen xml files (only supported source for now)

peg-custom parse --source "/my-C-library/doxygen/xml/files" --headers "/path/to/my-C-library/header/files"

Finally generate source code for the extension from previously extracted symbols.

peg generate

When Im back to my development computer I will try to comment here on my testing with wxWidgets
