LGI is gobject-introspection based dynamic Lua binding to GObject based libraries. It allows using GObject-based libraries directly from Lua.
Licensed under MIT-style license, see LICENSE file for full text.
Home of the project is on GitHub.
LGI is tested and compatible with standard Lua 5.1 and Lua 5.2 and recent LuaJIT 2 betas. Compatibility with other Lua implementations is not tested yet.
If you need to support pre-gobject-introspection GTK (ancient GTK+ 2.x releases), use Lua-Gnome.
In order to be able to compile native part of lgi,
gobject-introspection >= 0.10.8 development package must be installed,
although preferred version is >= 1.30. The development package is
libgirepository1.0-dev on debian-based systems (like Ubuntu)
gobject-introspection-devel on RedHat-based systems (like Fedora).
luarocks install lgi
Alternatively, use make-based installation:
make [sudo] make install [PREFIX=<prefix>] [DESTDIR=<destdir>]
Please note that on BSD-systems you may need to use 'gmake'.

- Avoid unexpected dependency on cairo-devel, cairo-runtime is now enough
- Make set_resident() more robust and fix stack leak for lua5.2 case, avoid useless warning when set_resident() fails (to accomodate for static linking case).
- Fix small memory leak (mutex) which occured once per opened lua_State using lgi.
- objects and structs: actually implement '_type' property as documented
- tests: Fix regression tests for less common platforms
- Pango: Add a few missing overrides
- cairo: Fix Context:user_to_device() family of methods.
- GStreamer: Add support for transfer!=none for input objects. This is needed to avoid leaks caused by strange usage of transfer annotations of gstreamer-0.10
- GStreamer: Add more missing overrides
- GStreamer: Fix and improve samples
- Various fixes for usecase when lua context with loaded lgi is closed and opened again
- Gtk: Add missing Gtk.Builder:connect_signals() override
- Add cairo bindings, cairo sample and finish some gtk-demo parts which were requiring cairo
0.5.1 (not officially released)
- Fix a few problems on more exotic architectures (s390x, mips, ia64).
- Allow passing
byte.bufferwhen UTF8 string is requested.
- Port gtk3-demo to Lua code. Try running 'lua samples/gtk-demo/main.lua'
- Finish override set for Gtk
- Extend and document features for interfacing LGI with external libraries (exporting and importing objects and structures via lightuserdata pointers).
- Fix: a few bugs with resolving bitflags values
- Fix: a few bugs in coroutines-as-callbacks feature
- Fix: workaround for crashing bug in gobject-introspection 1.32.0
- Fix: don't try to squeeze GType into lua_Number any more; this could cause crashes on some 64bit arches.
- Changed handling of enums and bitflags, switched from marshaling them as numbers to prefering strings for enums and tables (sets or lists) for bitflags. Numeric values still work for Lua->C marshalling, but backward compatibility is broken in C->Lua enum and bitflags marshalling.
- Compatible with Lua 5.2 and LuaJIT
- Added standardized way for overrides to handle constructor argument table array part.
- Existing Gtk overrides reworked and improved, there is now a way to
describe and create widget hierarchies in Lua-friendly way. See
docs/gtk.lua, chapter about
Gtk.Containerfor overview and samples.
- Various bugfixes and portability fixes.
- Project hosting moved to GitHub.
- Build system switched from
wafto simple Makefile-based one
- Added automatic locking of thread-sensitive libraries (Gdk and
Clutter). There is no need to add
Clutter.threads_leave()pairs into application, lgi handles this automatically.
- Added new sample
samples/console.lua, which implements already quite usable Lua console using Gtk widgets.
- Fixes for compatibility with older gobject-introspection 0.10.8 package
- Testsuite is not built automatically, because building it can be apparently problematic on some systems, causing installation failure even when testsuite is not needed at all.
setlocale()initialization, which could break Lua when used with some regional locales. The downside of this change is that marshaling file names containing non-ASCII characters on systems which define
G_BROKEN_FILENAMESenvironment variable (probably only Fedora 15) does not work now.
