Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

Functions, Macros, and Special Forms

• apply-template

  Function v1.0

  (apply-template argv expr values)
  

  For use in macros. argv is an argument list, as in defn. expr is
  a quoted expression using the symbols in argv. values is a sequence
  of values to be used for the arguments.
  
  apply-template will recursively replace argument symbols in expr
  with their corresponding values, returning a modified expr.
  
  Example: (apply-template '[x] '(+ x x) '[2])
  ;=> (+ 2 2)

• do-template

  Macro v1.0

  (do-template argv expr & values)
  

  Repeatedly copies expr (in a do block) for each group of arguments
  in values. values are automatically partitioned by the number of
  arguments in argv, an argument vector as in defn.
  
  Example: (macroexpand '(do-template [x y] (+ y x) 2 4 3 5))
  ;=> (do (+ 4 2) (+ 5 3))
