LuaJIT
======

Description
-----------

LuaJIT is a Just-In-Time Compiler (JIT) for the :ref:`lua` programming language.  It may be embedded or used as a general-purpose, stand-alone language.  LuaJIT can dramatically speedup Lua programs and provides a simple interface for calling C functions and using C data structures from pure Lua code.

User instructions
-----------------

LuaJIT is available via the modules system.  To add it to your environment run:

.. code-block:: bash

    $ module load luajit/2.0.5

LuaJIT can then be run by executing

.. code-block:: bash

    $ luajit

Documentation is available via the man page and the `LuaJIT website <http://luajit.org>`_.

Admin notes
-----------

The installation path needs to be set by changing the PREFIX variable in the top-level Makefile.  Compilation and installation is then straightforward: using the builder account on a workstation I did (inside the extracted LuaJit source tree):

.. code-block:: bash

    $ make
    $ make install
