:: clay (4c), revision control !: :: The way to understand Clay is to take it section-by-section: :: :: - Data structures. You *must* start here; make sure you understand :: the entire contents of +raft. :: :: - Individual reads. +aver is the entry point, follow it through :: +read-at-aeon to understand each kind of read. :: :: - Subscriptions. +wake is the center of this mechanism; nothing :: else responds to subscriptions. +wake has no arguments, which means :: every subscription response happens when something in Clay's *state* :: has changed. No edge-triggered responses. :: :: - Receiving foreign data. For individual requests, this is :: +take-foreign-answer. For sync requests (%many, which is %sing %v :: for a foreign desk), this is +foreign-update. :: :: - Ford. +ford builds hoon files and gives files their types. :: Read +build-file for the first, and +read-file is the second. :: :: - Writing to a desk. Every write to a desk goes through +park, read :: it thoroughly. :: :: - Merges. Control flow starts at +start-merge, then +merge, but :: everything is scaffolding for +merge-by-germ, which is the ideal of :: a merge function: it takes two commits and a merge strategy and :: produces a new commit. :: :: - Tombstoning. This is in +tomb. :: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: :: Here are the structures. `++raft` is the formal arvo state.
