Add a variable to a class instance at runtime: Difference between revisions

'''Array:'''

In this example we add a function (which prints out the content of the array) and a new value. While we are not technically adding a "variable", this example is presented to show similar type of functionality.

vect.dump = function ()

for n in [0: self.len()]

end

vect += 'delta'

'''Dictionary:'''

In this example we will add a variable through the use of an object from a bless'ed dictionary. We create a new variable called 'newVar' at runtime and assign a string to it. Additionally we assign an external, to the object, function (sub_func) to the variable 'sub'.

self['prop'] -= value

return self.prop

])
