        task_gen

Most methods are of the form 'def meth(self):' without any parameters there are many of them, and they do many different things: * task creation * task results installation * environment modification * attribute addition/removal

The inheritance approach is complicated * mixing several languages at once * subclassing is needed even for small changes * inserting new methods is complicated

This new class uses a configuration table: * adding new methods easily * obtaining the order in which to call the methods * postponing the method calls (post() -> apply)

Additionally, a 'traits' static attribute is provided: * this list contains methods * the methods can remove or add methods from self.meths Example1: the attribute 'staticlib' is set on an instance a method set in the list of traits is executed when the instance is posted, it finds that flag and adds another method for execution Example2: a method set in the list of traits finds the msvc compiler (from self.env['MSVC']==1); more methods are added to self.meths

Nested Classes

__metaclass__
no decorators for classes, so we use a metaclass we store into task_gen.classes the classes that inherit task_gen and whose names end in '_taskgen'

Instance Methods

__init__(self, *kw, **kwargs)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

__setattr__(self, name, attr)
x.__setattr__('name', value) <==> x.name = value

source code

to_list(self, value)
helper: returns a list

apply_core(self)

source code

apply(self)
order the methods to execute using self.prec or task_gen.prec

source code

post(self)
runs the code to create the tasks, do not subclass

subclass if necessary
