MDScript Object Oriented Programming

[Rophs]

Does MDScript offer features of OOP?

[Kaya]

Sadly the closest you can get to it is arrays, as far as I know. You can't even define your own functions.

 

Edit: You can define your own functions.

You can find a compilation of the MDScript available functions in the Wikia:

I tried playing around with MDScript a little more and apparently you can use functions. That being said I haven't found a way to use variables from outside a function (other than passing them as parameters and returning them) inside the function. In that sense it is more like functional programming than OOP. Also it doesn't appear to be possible to use MDScript specific methods inside a user defined function.
 
e.g: 

function bar()
{
    echo @vv; //Always echoes nothing
    @vv = 'bar';
}
 
@vv = 'foo';
bar();
echo @vv; //echoes foo
 
function baz(@vv)
{
    @vv = 'baz';
    return @vv;
}
baz(@vv);
echo @vv; //still foo
 
@vx = baz(@vv);
echo @vv; //still foo
echo @vx; //vx is now baz
 
function err()
{
    echo uv('id');
}

err(); //Gives an error because uv is undefined

Tried using global keyword?

Tried passing them in?

Global is a restricted keyword (thrice even) so that doesn't work.

As for passing in the methods, you can pass in the return values, but other than that not sure how it would work. (It is, for fairly obvious reasons, not possible to call a method stored in a variable, if that is what you mean.)

I shall add that to my list to review. we can probably expose the functions by default or via namespacing.

Not possible in MDscript, or PHP? http://php.net/manual/en/functions.variable-functions.php

Not possible in MDScript, which makes sense because there is no control over what code is saved inside the variable, allowing it to bypass all restrictions.

You can use MDScript specific functions from within your own functions, but you have to add:

(prepare function)

on the first line inside the body of the function.
