Type Alias: OperatorMatch ​

OperatorMatch = { matched: false; } | { matched: true; token: OperatorToken; kind: OperatorKind; targetPath: SemanticPath; rewrittenExpression?: any; memoryOperator?: string; returnsValueAtRoot?: boolean; }

Defined in: types.ts:178

Operator recognition can either match (and then execute) or pass.

Type Declaration ​

{ matched: false; }

matched ​

matched: false

{ matched: true; token: OperatorToken; kind: OperatorKind; targetPath: SemanticPath; rewrittenExpression?: any; memoryOperator?: string; returnsValueAtRoot?: boolean; }

matched ​

matched: true

token ​

token: OperatorToken

The operator token that matched (e.g. "_", "=")

kind ​

kind: OperatorKind

The operator kind from the registry

targetPath ​

targetPath: SemanticPath

The destination path that should receive the semantic write (operator leaf removed or otherwise transformed). In me.ts this is typically scope.

rewrittenExpression? ​

optional rewrittenExpression: any

The expression to write after the operator transforms it. e.g. pointer operator turns expression:string into

memoryOperator? ​

optional memoryOperator: string

If operator is producing a semantic memory, what should be recorded as operator. (me.ts uses "" for both "" and "->" pointer calls).

returnsValueAtRoot? ​

optional returnsValueAtRoot: boolean

Some operators return a value instead of writing when invoked at root.

  • root "=" thunk returns computed value
  • root "?" returns collected/transformed output
