Luna is a bytecode register interpreter for Lua. At the moment it uses Luajit to compile Lua files to bytecode and interprets it.
You'll need to have a few dependencies installed. You can get them with pip install -r requirements.txt. Then make sure you have a recent checkout of
PyPy and have it on your PYTHONPATH. Finally you need a
recent version of luajit (luajit -b is used to generate
the bytecode).
To run the tests::
$ py.test
To translate run::
$ python translate.py
This will compile Luna, it'll take about 30 seconds.
To run Luna directly on top of Python you can do::
$ python -m luna /path/to/file.lua
- Compiler in Rpython
- Interators
- JIT
- more standard library functions
At the moment, Luna supports most of the Lua standard constructs, except iterators.
Following parts of the standard library (the code can be found in luna/modules) have been implemented:
- Builtins
- assert
- loadfile
- loadstring
- tonumber
- type
- math
- floor
- sin
- mod
- table
- concat
- insert
- remove
- string
- find
