Object oriented batch

Objectbatch is an object-oriented extension of the Windows batchfile language, including classes and instances, methods and attributes, inheritance, encapsulation, polymorphism and object composition.

Simple use of a class instance:

::instantiate new object obj of type MyClass
call new MyClass obj construct

::calling method myMethod of instance obj
call # obj myMethod

::reading obj attribute myAttr
echo !%obj%.myAttr!

::writing obj attribute myAttr
set %obj%.myAttr=1

Simple class definition:

::boilerplate
call class %*
%class%

::this is the constructor, adding one custom attribute attr
:public-construct
    call super %*
    set %self%.attr=0
exit /b

More information

For more information on the various object-oriented features available, please have a look at the examples and the wiki.

An example object-oriented batchfile repository can be found here.

Limitations

• Changed object state within a local scope (setlocal) can only persist by using save.bat.
• Batchfile bug: it seems that instantiating many objects at once causes older objects to vanish. Circumvent this issue by serialising with save.bat.
