Lua Development Tools (LDT) is about providing Lua developers with an IDE providing the user experience developers expect from any other tool dedicated to a static programming language.

Like many other dynamic languages, Lua is so flexible that it is hard to analyze enough to provide relevant and powerful tooling.
LDT is using Metalua, to analyze Lua source code and provide nice user assistance.

LDT is an Open Source tool, licensed under the EPL.

Standalone product

If you are not a regular Eclipse user, or simply don't want to clutter your regular development environment with the LDT plug-ins, you might want to download a ready-to-use Eclipse product.
All you have to do is download the distribution corresponding to your platform of choice, unpack the archive (~60 MB), and launch the LuaDevelopmentTools executable.
We advise you to get the stable version, but if you want to test the latest features you should get the milestone version.

Version Windows Mac OS X Linux
Stable release (1.2) 32-bit - 32-bit
64-bit 64-bit 64-bit

Please be aware that the milestone version can be unstable, and may contain bugs (please report them if this is the case!).

Inside an existing Eclipse installation

Add the following repository: from the "Help > Install New Software..." menu of your Eclipse 4.3+ workbench, and then check the "Lua Development Tools" feature.
Should you want to install a different version than the latest stable one, check on the wiki the other update repositories available.
