link

link is one arc of the worked example: a small directed delivery network where the obvious route is the wrong one twice over.

network

source

The source of the worked example, and a node nothing reaches, to show that unreachable is an answer rather than an error.

isolated

The source of the worked example, and a node nothing reaches, to show that unreachable is an answer rather than an error.

fanout

fanout is the determinism example: one hub, three spokes, all at the same cost. Which one settles first is decided by the order they were declared in, never by a map.

Render

Render renders the demo for gnoweb. Render("") / Render("/") -> the full demo

route

route joins a path with an arrow. Each node name is escaped on its own and the separator never is: running the whole joined string through the escaper would turn the arrows into a literal backslash soup, which is the bug this spelling exists to avoid.

names

names renders a declaration order as a comma-separated list, escaped the same way.

settleFanout

settleFanout builds the hub-and-spoke graph with the spokes declared in the given order and returns the order the search settles them in.

reverse

reverse copies a slice back to front. Written out rather than imported because there is no sensible shared home for three lines of it.
