BiwaScheme JavaScript API

Moved to reference.md

Type conversion

• Scheme number == JavaScript number

• Scheme string == JavaScript string

• Scheme vector == JavaScript array

• Scheme nil = BiwaScheme.nil

• Scheme pair = BiwaScheme.Pair

  • make a pair in js : new BiwaScheme.Pair(1, 2)
  • check x is a pair : BiwaScheme.isPair(x) (returns false for nil)
  • check x is a proper list : BiwaScheme.isList(x) (returns true for nil)
  • pair -> js array : list.to_array()
  • js array -> list (shallow): BiwaScheme.array_to_list(1, 2, [3]) => (list 1 2 (vector 3 4))
  • js array -> list (deep): BiwaScheme.deep_array_to_list(1, 2, [3]) => (list 1 2 (list 3 4))
  • alist -> js obj : BiwaScheme.alist_to_js_obj(alist)
    • eg. '((a 1) (b 2)) is converted to {a: 1, b: 2}
  • js obj -> alist : BiwaScheme.js_obj_to_alist({a: 1, b: 2})

• Scheme symbol = BiwaScheme.Symbol

  • js string -> symbol : Sym("asdf")
  • symbol -> js string : sym.name

• Scheme function = an array, with ary.closure_p is set to true

  • BiwaScheme.isClosure(x) returns true when x is a Scheme function
