Overview

Package all provides additional primitives for records, promises, and extended string/character operations.

Records (R7RS 5.5)

  • make-record-type, record-type?
  • make-record, record?, record-type-of
  • record-ref, record-set!

Promises (R7RS 4.2.5)

  • make-promise, promise?
  • force

Extended String Operations

  • string-copy, string-copy!, string-fill!
  • substring, list->string, string->list

Extended Character Operations

  • char-alphabetic?, char-numeric?, char-whitespace?
  • char-upper-case?, char-lower-case?
  • char-upcase, char-downcase, char-foldcase

Use Extension or AddToRegistry to register all primitives.

Package all provides a convenience extension that includes all standard extensions.

func PrimForce 

func PrimForce(_ context.Context, mc *machine.MachineContext) error

PrimForce implements the (force) primitive. Forces evaluation of a promise with proper memoization.

R7RS §4.2.5: The first time a promise is forced, its body is evaluated and the result is memoized; on subsequent forces, the memoized result is returned.

func PrimIsRecord
