[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [57478] trunk/blender/scons: Long overdue update for our bundled SCons version, from 1.2.0 (20090223) to current stable 2.3.0.

Sat Jun 15 23:26:10 CEST 2013

Cool!
Thanks for that, this could help with vs2012 support issues on scons builds.

> +
> +A second-level base class is _ActionAction.  This extends ActionBase

> +
> +    CommandAction
> +    CommandGeneratorAction
> +    FunctionAction
> +    ListAction
> +
> +The subclasses supply the following public interface methods used by
> +other modules:
> +
> +    __call__()
> +        THE public interface, "calling" an Action object executes the

> +
> +    get_contents()

> +
> +    genstring()
> +        Returns a string representation of the Action *without*
> +        command substitution, but allows a CommandGeneratorAction to
> +        generate the right action based on the specified target,
> +        source and env.  This is used by the Signature subsystem
> +        (through the Executor) to obtain an (imprecise) representation
> +        of the Action operation for informative purposes.
> +
> +
> +Subclasses also supply the following methods for internal use within

> +
> +    __str__()
> +        Returns a string approximation of the Action; no variable
> +        substitution is performed.
> +
> +    execute()
> +        The internal method that really, truly, actually handles the
> +        execution of a command or Python function.  This is used so
> +        that the __call__() methods can take care of displaying any
> +        pre-substitution representations, and *then* execute an action
> +        without worrying about the specific Actions involved.
> +
> +    get_presig()
> +        Fetches the "contents" of a subclass for signature calculation.
> +        The varlist is added to this to produce the Action's contents.
> +
> +    strfunction()
> +        Returns a substituted string representation of the Action.
> +        This is used by the _ActionAction.show() command to display the
> +        command/function that will be executed to generate the target(s).
> +
> +There is a related independent ActionCaller class that looks like a
> +regular Action, and which serves as a wrapper for arbitrary functions
> +that we want to let the user specify the arguments to now, but actually
> +execute later (when an out-of-date check determines that it's needed to
> +be executed, for example).  Objects of this class are returned by an
> +ActionFactory class that provides a __call__() method as a convenient
