var.list is a function that is part of the Var Library.
The function returns a table with all the names of variables currently defined in the document.
Syntax
var.list()
returns a table with variable with variable names.
Example
function on.paint(gc)
variables = var.list()
for i=1, table.getn(variables) do
gc:drawString(variables[i], 10, 10*i-10, "top")
end
end
This code retrieves the variable names and then prints them on the screen.
