Package Ki provides the base element of GoKi Trees: Ki = Tree in Japanese, and "Key" in English -- powerful tree structures supporting scenegraphs, programs, parsing, etc. The Node struct that implements the Ki interface, which can be used as an embedded type (or a struct field) in other structs to provide core tree functionality, including: Parent / Child Tree structure -- each Node can ONLY have one parent. Node struct's can also have Node fields -- these are functionally like fixed auto-named children. Paths for locating Nodes within the hierarchy -- key for many use-cases, including ability to convert pointers to/from strings for IO and robust deep copy and move functions. The path separator is / for children and . for fields. Apply a function across nodes up or down a tree (natural "me first", breadth-first, depth-first) -- very flexible for tree walking. Generalized I/O -- can Save and Load the Tree as JSON, XML, etc -- including pointers which are saved using paths and automatically cached-out after loading -- enums also bidirectionally convertable to strings using enum type registry in kit package. Robust deep copy, clone, move of nodes, with automatic pointer updating. Signal sending and receiving between Nodes (simlar to Qt Signals / Slots) -- setup connections once and then emit signals to all receivers when relevant event happens. Robust state updating -- wrap updates in UpdateStart / End, and signals are blocked until the final end, at the highest affected level in the tree, at which point a single update signal is sent -- automatically gives the minimal update. Properties (as a string-keyed map) with property inheritance, including type-level properties via kit type registry.
