Possibillity of Oriented Object Programming in SARL about sarl HOT 6 CLOSED

Do you suggest to add a syntax for object oriented language in SARL file?

from sarl.

Yes, as we need to mix oriented object and agent programming in SARL it could be interesting to offer the possibility to create an object in sarl.

I think a good approach will be to import the Xtend grammar and adapt it to your specific syntax (variable definition...). Currently, it is mostly in this way by extending the Xbase, which is providing the support for expressions.

The question is: do we want to depend on Xtend?

from sarl.

I am not sure that we should have a mixed OOP and AOP in SARL files. I rather have Xtend files for OOP and SARL for AOP. I use Xtend since its syntax is closer to SARL.
This enables programmers to use any OO programming language they want for OOP as long as it is compatible with java (Xtend, Scala, groovy, etc)

What do you think?

from sarl.

I think we could provide the ability to the SARL developers to define OO data structures inside the context of the SARL agent. It is similar to the definition of inner classes in this context.

A typical example is the definition of the states of an agent in an enumeration type. It is not friendly to define the enumeration outside the agent in Java (or any other language). Since the states of the agents are only related to the agent, they should be accessible by other classes or agents. The inner definition in the agent may provide a solution to this small problem.

Additionally,supporting some OO statements (I'm not sure we should support all the OO syntax; we should decide) has a couple of advantages:

• Make easier and faster to code in SARL (all in one file).
• The developer could only know SARL; no need for mastering another language.
• By including some OO features, we could benefits from the tools provided by Xtend (validator, etc.) that may provide partial answers to the SARL issues related to inheritance.

A recent example of integration of OOP and AOP is Scala and its actor extension.
