# FFI binding tools

The goal of this tools is to make FFI binding creation easier means it

read C headers and generate binding definitions automaticall. I think

writing those file is not something human should do.

# How to use

The `genbind` is the script to generate a binding files. Following is the

example command.

    $ genbind -o "(foo)" -t intptr_t=int -t uintptr_t -s shared.txt \

      test_files/includes/defs.h

This creates 4 files with following structure

- generated

   - foo.scm

      - apis.scm

      - constants.scm

      - types.scm

Command line options are followings;

    -o,--output   Top most output library name.

    -s,--shared   Shared object location definition file. 

    -t,--typedef  Predefined typedef.

      This can have following forms;

        _name_

        _name_=_value_

      _name_ is the defined name. If _value_ is given then following form

      will be emit in the `type.scm` file.

      (define-c-typedef _value_ _name_)

    -D,--define   Preprocessor definition.

    -c,--convert  C function name conversion type.

      scheme: convert camel to snake and '_' to '-'.

      snake:  convert camel to snake.

      under:  convert '_' to '-'

      none:   no conversion.

# TODO

- resolving preprocessor should be done in C parser.

- creating better AST representation.

- better error reporting.

- better source tracking.

Your contribution is always welcome :)
