Usage

Overview

Valabind is a program written in Vala that aims to generate nodejs, c++ or SWIG interfaces (.i) from a vala-generated or hand-made vapi files.

SWIG opens the door to create bindings for Python, Perl, ruby, lua, and many other scripting languages.

-h

show help message

-o OUTPUT

specify output file name

-m NAME

specify module name

-N NS

include given namespace for processing

-D SYMBOL

define a preprocessor symbol inside Vala code

-p PROFILE

select Vala profile (posix, gobject, dova)

-x

generate c++ code for SWIG bindings

-v

show version information

-V PATH

specify an alternative vapidir path

Notes

Valabind processes a single module at a time: the module named with -m is the only one whose classes, structs, enums and methods are emitted in the output. Any additional vapifile arguments passed on the command line are not processed as independent modules — only the first class of the first file ends up being walked.

To resolve types that come from other modules (e.g. a r_core.vapi that references symbols declared in r_asm.vapi), drop the extra vapis and their sibling .deps files under the directory passed to -V VAPIDIR and invoke valabind with just the single positional vapi you want emitted. Reproducing the pipeline by hand with every .vapi on the command line is a common mistake and will silently produce a nearly empty binding.

Environment

XDG_DATA_DIRS

Standard freedesktop environment variable to point to the share prefix directory where vala looks for vapi files.
