Overview

Interpreter internals ===

A native (Ruby-implemented) function. Apply treats it like a Func.

Constant Summary collapse

Atom = A scalar literal value: the JSON atoms plus NULL (everything the lexer emits as a token value, see Lexer#lex_number and #lex_word).

->(v) {
  v == NULL ||  v == true || v == false ||
    v.is_a?(Integer) || v.is_a?(Float) || v.is_a?(String)
}

NULL =

:null

Token = type: one of the lexer’s token-type symbols (:number, :ident, :lparen, …). value: the token’s payload — a scalar for literals/keywords, the matched text for punctuation/identifiers, or nil for :eof. pos: the token’s source offset.

TypedData.define(
  type: Symbol,
  value: ->(v) { Atom === v || v.nil? },
  pos: Integer,
)

VERSION =

"0.0.1.alpha2"

WirePair =

TypedData.define(status: ->(v) { Integer === v && [0, 1].include?(v) }, data: String)
