Re: pseudo self modifying code?

[Gaspard Bucher <gaspard@...>]

Have you thought about LuaSQLite ? With some simple wrappers in Lua (metatables), you can use table syntax to read and update your data:

device = db:device('device name')

-- read db

print(device.name)

-- update db

device.name = xxx

If you really need to be able to hand edit the result, YAML is a very good choice. JSON (or Lua tables) tend to become unreadable.

You can overcome that limitation by splitting data into several
functions that will be run by the loading "dofile" call.

The other limitations are harder to circumvent easily. I personnally
used such a scheme for a project of mine, and switched to CouchDB when
my data grew too big. Document-based databases like CouchDB can let
you implement very easy to use and almost transparent backends for big
Lua structures.
