Calc DSL

some math DSL for calculation in Cirru.

Demo http://r.tiye.me/mvc-works/calc-dsl .

Usage

Eval tree expression with variables:

calc-dsl.core/calc-x-code "|+ x 1" 2
; => 3

Code is in Cirru syntax:

calc-dsl.core/calc-code "|+ x 1"
  &{} |x 2
; => 3

calc-dsl.core/calc-code "|+ x $ * x x"
  &{} |x 2
; => 6

Also skip parsing and eval tree:

calc-dsl.core/calc-expr ([] |+ |x |1)
  {} (|x 2)
; => 3
