Recent revs add the following new position methods:
- p.is_at_all(): True if p is an @<file> node containing an @all directive.
- p.in_at_all(): True if p is in an @<file> tree whose root contains @all.
- p.is_at_ignore(): True if p is an @ignore node
- p.in_at_ignore_tree(): True if p is in an @ignore tree.
These predicates make it easy to create other predicates that skip @ignore
trees or @<file> trees containing @all. cffm and cfam do *not *skip such
trees, on the theory that one would typically unmark nodes first before
marking nodes to be cloned.
So here is how to gather only those marked nodes that lie outside any
@ignore tree:
def isMarked(p):
return p.isMarked() and not p.in_at_ignore_tree()
self.cloneFindByPredicate(
generator = self.all_unique_positions,
predicate = isMarked,
flatten = flatten,
undoType = 'gather-marked',
)
