Use Vala from Ruby, Python, Lua, JavaScript (Node.js, gjs, seed) and many other languages

Use Vala for your next library, %username%

Write your next library in Vala and get bindings for free!

Here is example how to use functions and objects from vala in your favorite language.

Why Vala?

• Vala is very fast
• Vala manages memory for you
• Write in Vala, (re)use from any %lang%

Setup Vala

Debian/Ubuntu

sudo apt-get install valac gobject-introspection libgirepository1.0-dev

Fedora

sudo yum install vala gobject-introspection-devel

OSX

brew install vala gobject-introspection

Make shared library

Source file for shared library is object.vala.

Run in shell:

make

You should get vala-object.so and ValaObject-0.1.typelib and some other files. .so and .typelib are required for next examples.

If you want more details - read about GObject Introspection and it's architecture. Otherwise just skip to next step :)

Bindings HOWTO (really easy and automagical)

• Ruby (Ruby 1.9.1, JRuby and Rubinius)
• Python
• Perl
• Lua (Lua 5.1 and LuaJIT 5.1)
• JavaScript (Node.js, seed and gjs)
• PHP
• Other languages

• Mailing list: vala
• IRC: #introspection and #vala at irc.gnome.org

vala-object's Issues

node.js example works now

I've tested your node.js example with the new node-gir version 0.1.0 and it works full now.
I've fixed the example in my fork.
Please update your Repository, thanks.

Generates broken gir bindings.

If one adds a constructor to the class, at least in python w/ gir, the constructor is never called when the object is instanced in python (yes, after regenerating the bindings) if you're using c#/java style constructors. The deconstructor is bound correctly, and so are gobject style constructors.

Probably not a bug with this project, but noting it as a warning to others who might use this as a basis for other projects.

Perl example

test.pl / make run-perl (same as python's)

!/usr/bin/perl

use Glib::Object::Introspection;

Glib::Object::Introspection->setup(
basename => 'ValaObject',
version => '0.1',
package => 'ValaObject',
search_path => 'build');

ValaObject->say_hello_to("Perl");

Cant build Java

make bind

...
ibobject_wrap.cxx:178:10: fatal error: jni.h: No such file or directory
  178 | #include <jni.h>
      |          ^~~~~~~
compilation terminated.
make: *** [Makefile:11: bind] Error 1

is this project active

I want write my python module with vala and search google then get this..................

is this project active?????

LuaJIT 5.2 Support

Hello,

I'd love to see LuaJIT 5.2 support added.

Thanks for the cool library, really fulfills the reason why Vala was created (I feel)!

Cant run Ruby

sh-5.0$ ./run.sh test.rb 
Traceback (most recent call last):
	2: from test.rb:1:in `<main>'

Dead?
