Re: Saving a table in file

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

Wonderful! It's really wonderful. When I mentioned I would like something 
really simple, I could not imagine how simple it would be! With Data e Json, 
I could do everything I wanted.

I always admire Python for the simpliicity. For the same reason, I admire 
Lua. I have started in Lua because of IUP. Now I can't imagine to adopt 
another language.

A gift... What you sent me was a gift.

There is choices more complicated, adopted by people I respect. But I am 
sure that for my simple needs, Data and Json are perfect. Both are excelent.

Thank you!

As mentioned, you need to serialize (i.e. create a string representation) 
your table.

For example:

local Data = require( 'Data' )

-- save the content of table 't' to file 't.txt'
Data[ 't.txt' ] = t

-- load the content of file 't.txt' into variable 't'

t = Data[ 't.txt' ]

-- print the content of table 't' as a string
print( Data( t ) )

_[1]={}
_[1]["city"]="São Paulo"
_[1]["country"]="Brazil"
_[2]={}
_[2]["city"]="Napoli"
_[2]["country"]="Italy"
_[3]={}
_[3]["city"]="Nantes"
_[3]["country"]="France"
_[4]={}
_[4]["city"]="Chicago"
_[4]["country"]="United States"
