Important

Cacco is still in the design stage. It’s not working yet.

Introduction

Comment

;; This is inline comment (to the end of the line).

(; (1)
  This is block comment.
  block comment is keeping until the terminator -> ;) ;; (2)

(;
  (; These block comments can be nested. ;)
;)

1. (; is the start of block comment

2. ;) is the end of block comment

Literals

0     ;; Fuzzy Numeric.  (default: Natural)
-1 +1 ;; Fuzzy Integer.  (default: Integer)
0.0   ;; Fuzzy Decimal.  (default: Decimal)
1/2   ;; Rational.
'a'   ;; Character.      (same as Uint32)
""    ;; Fuzzy Text.     (default: String_UTF8)
:key  ;; Keyword.
[]    ;; Fuzzy Sequence. (default: List)
{}    ;; Key-Value Map.

Fuzzy Types	Include Types
Fuzzy-Numeric	Uint8, Uint16, Uint32, Uint64, Natural, and Fuzzy-Integer
Fuzzy-Integer	Int8, Int16, Int32, Int64, Integer, and Fuzzy-Decimal
Fuzzy-Decimal	Float16, Float32, Float64, Flonum
Fuzzy-Text	Bytes, String-UTF8, String-UTF16, String-UTF32
Fuzzy-Sequence	List, Vector, Array, Sequence

Declaration and Reassign

;; Declare procedure or constant value or variable value.
(: x Integer)

;; Declare a constant value once.
(= x 1000)

;; Declare a mutable variable value.
(:= y 0)

;; Strictly typing with literal.
(= z (: 0 Uint8))
(:= w (: "something" Bytes))

;; Reassign
(=! y 1000)    ;; OK
(=! y "hello") ;; Can't. `y` has been declared as Number type.
(=! x 10)      ;; Can't. `x` has been declared as immutable.

Calling procedure

;; Simply calling a procedure.
(foo a b c)

;; Calling closure.
((|a| (* a a)) 10) ;; returns 100

Define procedure

;; Declare a procedure
(: cubic (-> Number Number)) ;;(1)

;; Define the procedure
(= (cubic x) (* x x x))

1. (→ T1 T2 …​ Tn) is Function type receive T1, T2 …​ then return value as Tn type.

Development

Prerequisites

• Haskell Stack

Build and Testing

Simply building libraries and application

stack build

Clean

stack clean

Run Tests

# simply run test-suites
stack test

# run test-suites and generate coverage-report
stack test --coverage

# open coverage-report in your browser
open $(stack path --local-hpc-root)/index.html

Check Haddock

stack haddock
