[ANN] lgi 0.2 - Lua to GObject (GNOME) libraries binding

[Pavel Holejsovsky <pavel.holejsovsky@...>]

Hello lua-l readers,

I'm happy to announce that after more than year of development, lgi 
project finally made it to the first public alpha release.

Lgi is binding of GObject-based libraries to Lua using dynamic form of 
GObject Introspection.  This means that you can use GI-enabled GObject 
library from Lua without the need to compile any C code, just having 
appropriate .typelib installed for target library is enough.

* License:
MIT-X11

* Features:
- Allows querying and instantiating GObject-based classes, invoke 
methods, functions, read and write properties and connect signals
- Fully dynamic binding, no additional C code is needed to compile to 
access any GI-enabled library
- Has syntactic sugar for easy work with GObject primitives - mainly 
GType, GValue and GClosure
- Contains wrappers for Lua-friendly work with GVariant

* Requirements:
- Installed and working gobject-introspection library >= 0.10.8 
(distributed with GNOME3.0, e.g. Fedora15), but some features are 
available only with gobject-introspection >= 1.30 (available with 
GNOME3.2, e.g. Fedora16).
- Target library must be compiled with GI support, i.e. has installed 
.typelib file (all Linux distributions I know fulfill this).
- Tested only with Lua 5.1.4, should work with current LuaJIT (but does 
not use ljffi yet).  Most probably does not work yet with Lua 5.2

* Known problems:
- 0.2 release triggers bug in gobject-introspection 0.10.8 causing 
crashes when running on 32b architectures.  x86_64 works fine, and fix 
for gi-0.10.8 on x86 is already in lgi git master.
- GVariant support works only when using gobject-introspection>=1.30

* Availability:
Preferably by luarocks, "luarocks install lgi".

* Documentation:
- There is documentation in markdown format, written in my terribly 
broken english.  Use your favorite markdown processor to turn it into 
something more fancy :-)
