Re: Non SQL databases

["Luciano de Souza" <luchyanus@...>]

Lua syntax is wonderful, but can I use a Lua script as a very small 
database?

Suppose I have this example:

-- module A

configuration =

{

param1 = 10,

param2 = 11,

param3 = 13

}

Suppose the parameters are colors. In a set of options, the user can change 
the the colors of interface and the new values should be stored. How to save 
the values in a source code? Is it possible? Or you are mentioned it only 
for readable parameters?

The first time I call "require('module1')" configuration.param1 = 10. But 
the user said it will be 25. How to save it and recharge Module1 with the 
new value: configuration.param1 = 25?

If this is possible, Lua is much powerful and extraordinary than I could 
imagine!

What you said is really intersting.
