method for serializing lua tables


I may have missed this, but is there a built-in method for serializing/deserializing lua tables to text files and vice versa?

I had a pair of methods in place to do this on a lua table with fixed format (e.g. 3 columns of data with 5 rows).

Is there a way to do this on lua tables with any arbitrary format?

For an example, given this lua table:

local scenes={
    {name="scnSplash",
        obj={
            {
                name="bg",
                type="background",
                path="scnSplash_bg.png",
            },
            {
                name="bird",
                type="image",
                path="scnSplash_bird.png",
                x=0, 
                y=682,
            },
        }
    },
}

It would be converted into text like this:

{name="scnSplash",obj={{name="bg",type="background",path="scnSplash_bg.png",},{name="bird",  type="image",path="scnSplash_bird.png",x=0,y=682,}},}

The format of the serialized text can be defined in any way, as long as the text string can be deserialized into an empty lua table.


Solution

  • require "json"
    local t = json.decode( jsonFile( "sample.json" ) )
