I am sorry for the lack of attention. The answer was clearly explained
in the documentation. The .constructor is called as: "self:super"
This code works:
class = require('pl.class')
class.control()
function control:_init(title)
self.title = title
end
class.window(control)
function window:_init(title)
self:super(title)
end
function window:show()
print(self.title)
end
window = window('Hello World')
window:show()

Hello listers,
I have tried some inheritance with Penlight class support. However, I
don't know how to call the parent constructor. This code fails, so I
ask: what is wrong:
class = require('pl.class')
class.control()
function control:_init(title)
self.title = title
end
class.window(control)
function window:_init(title)
control:_init(title)
end
function window:show()
print(self.title)
end
window = window('Hello World')
window:show()
