Function Import

[Inverness]

I had requested this feature along time ago and the new function objects have made it possible now.

This will create function pointers in an object. Variable list:
fromobj - Object, The object you want to import functions from.
toobj - Object, The object you want to import functions to.
fromprefix - String, Only import functions starting with this text. If null, all functions imported.
toprefix - String, Imported functions will be prefixed with this.
events - Boolean, Should functions starting with "on" be included in the operations?

PHP Code:

public function import(fromobj, toobj, fromprefix, toprefix, events) {
  temp.vars = 0;
  temp.i = 0;
  
  if (fromobj.type() != 2 || toobj.type() != 2) {
    echo("System: Import Error");
    return;
  }
  vars = fromobj.getFunctions();
  if (fromprefix != null) {
    for (i: vars) {
      if (i.starts("on") && events == false)
        continue;
      if (fromobj.(@ i).starts(fromprefix)) {
        if (toprefix == null) {
          toobj.(@ i) = fromobj.(@ i);
          toobj.importedfunctions.add(i);
        }
        else {
          toobj.(@ toprefix @ i) = fromobj.(@ i);
          toobj.importedfunctions.add(toprefix @ i);
        }
      }
    }
  }
  else {
    for (i: vars) {
      if (i.starts("on") && events == false)
        continue;
      if (toprefix == null) {
        toobj.(@ i) = fromobj.(@ i);
        toobj.importedfunctions.add(i);
      }
      else {
        toobj.(@ toprefix @ i) = fromobj.(@ i);
        toobj.importedfunctions.add(toprefix @ i);
      }
    }
  }
}
public function deport(obj) {
  temp.vars = 0;
  temp.i = 0;
  
  vars = obj.importedfunctions;
  for (i: vars) {
    obj.(@ i) = null;
  }
} 


Example:

PHP Code:

// WEAPON: InverTest
function testf(text) {
  echo("TESTF: " @ text);
}
function test2(text) {
  echo("Test2: " @ text);
} 


PHP Code:

// WEAPON: InverTest2
function onCreated() {
  System.import(InverTest, this, "test", null, false); // importing functions that start with 'test'
  testf("ZOMG");
  test2("RAWR");
  System.deport(this); // removes imported functions
} 


PHP Code:

// Example script
function onCreated() {
  System.import(MudControl, this, null, "mud_", false);
  // Importing all functions from MudControl and prefixing with mud_ to remove conflict.
} 


I've also noted that using this method can be used even if the imported functions are not public.
