Expand description

A portion of a name-binding path.

Partial paths can be computed incrementally, in which case all of the edges in the partial path belong to a single file. At query time, we can efficiently concatenate partial paths to yield a name-binding path.

Paths describe the contents of the symbol stack and scope stack at the end of the path. Partial paths, on the other hand, have preconditions and postconditions for each stack. The precondition describes what the stack must look like for us to be able to concatenate this partial path onto the end of a path. The postcondition describes what the resulting stack looks like after doing so.

The preconditions can contain scope stack variables, which describe parts of the scope stack (or parts of a scope symbol’s attached scope list) whose contents we don’t care about. The postconditions can also refer to those variables, and describe how those variable parts of the input scope stacks are carried through unmodified into the resulting scope stack.
