Single-File Object-Oriented Script?

Asked by Silas Henderson on 14 Jun 2019
Latest activity Commented on by Silas Henderson on 14 Jun 2019
How can I define a class and instantiate it within the same script? Something like ...
object = some_class()
while 1
object.method
end
classdef(some_class)
properties: ...
methods: ...
end
I understand that class definitions, in Matlab, are supposed to be implemented in separate files. I'm asking about some kind of work-around...
with the sole purpose of keeping the script self-contained, even if the actual program stretches out. A guess is shown below.
string = "classdef(.....)"
classdef_file = export-to-file(string)
load(classdef_file)
object = some_class()
while 1
object.method
end
... or maybe something with C code, or handle objects? Like... some way to make a 'pseudo-class' that acts like a class but has different implementation?
I'm putting this out there because someone must have found a similar solution for defining functions in the script prior to 2016.
Here are the half-solutions that I'm aware of:
  • Jupyter Notebooks with %%file method.
  • Define a structure and just use anonymous functions, a.b = @ (x) ...
If anyone finds or knows a solution, this would be awesome!

You could just create a static class method that runs what you would normally run in the workspace of the script,
classdef some_class
methods(Static)
function script_code
object = some_class();
while 1
object.some_method();
end
end
end
%% Non-Static class definitions
properties
...
end
methods
function some_method(obj)
end
....
end
end
