Method Details

[hide private]

check_name(self, name)

Return scope of name.

The scope of a name could be LOCAL, GLOBAL, FREE, or CELL.

force_global(self, name)

Force name to be global in scope.

Some child of the current node had a free reference to name. When the child was processed, it was labelled a free variable. Now that all its enclosing scope have been processed, the name is known to be a global or builtin. So walk back down the child chain and set the name to be global rather than free.

Be careful to stop if a child does not think the name is free.

add_frees(self, names)

Process list of free vars from nested scope.

Returns a list of names that are either 1) declared global in the parent or 2) undefined in a top-level parent. In either case, the nested scope should treat them as globals.
