Rulealize.Plugin.Record

Records in the state, for Rulealize rule sets.
Plugin id Rulealize.Plugin.Record
Namespace rec
Reserved prefix none
Depends on Rulealize.Abstraction
Specification doc/specification.md

rec.of and rec.map are schema nodes; rec.at, rec.has, rec.with and rec.keys are expressions; rec.set and rec.update are effects.

Why

state.schema is a flat map of field names to schemas, so anything shaped like a map has to be spread across one field per key. A shogi hand — seven kinds of piece for each of two players — costs fourteen fields, fourteen reads chosen by a two-level branch.match, and twenty-eight effects, because a state.set path is a literal and there is no way to say "the counter for this kind".

"hand": {
  "op": "rec.map", "keys": ["black", "white"],
  "value": { "op": "rec.map", "keys": ["P", "L", "N", "S", "G", "B", "R"],
             "value": { "op": "type.int", "min": 0 } }
}

That the path stays a literal is not what is being worked around. Literal paths are what make every path checkable before anything runs, what lets a document say which fields an input writes, and what keeps schema validation out of evaluation. This plugin adds the other half of a seam a grid already uses: the field is named literally and the inside is reached by the vocabulary of whoever owns it. There is no "hand.black.P", exactly as there is no "board.d3".

Lists did not need a plugin for the same reason a record did. A list field holds a Sequence, a kind in the value model with seq.count, seq.any and seq.where already pointed at it, so type.list in Rulealize.Plugin.TypeSchema is one schema node and no operations. A record had nothing, which is the whole of why this exists.

The one decision to know before reading the specification: the key set is closed, and reading a key that is not there is an error — deliberately unlike grid.at, which answers null for a square off the board. A board has squares that legitimately do not exist and Reversi's capture rule depends on reading one; a record's keys are all declared, so asking for another is a mistake and rec.has is how to ask first.

Building

dotnet build. Rulealize.Abstraction restores from nuget.org like any other package, so this repository builds on its own.
