Goldfish Scheme v17.11.2

> bin/goldfish --version
Goldfish Scheme 17.11.2 by LiiiLabs
based on S7 Scheme 11.2 (30-Dec-2024)

Goldfish Scheme v17.11.2 will be built-in in Mogan STEM Suite v1.2.9.9.

New Modules (liii lang)

The module improves the usability of Goldfish Scheme significantly

• Functional Data Pipeline like Scala collection or Java Stream API
• Unicode support by case-string and case-char

Demo Code for Unicode support

((box "你好，世界") 0) ; => 你
((box "你好，世界") 4) ; => 界
((box "你好，世界") :length) ; => 5

Demo code for functional data pipelines

((box (list 1 2 3 4 5))
 :map (lambda (x) (* x x))
 :filter even?
 :collect) ; => (list 4 16)

((box (vector 1 2 3 4 5))
 :map (lambda (x) (* x x))
 :filter even?
 :collect) ; => (vector 4 16)

Improved define-case-class

define-case-class is the Scala case class alternative in Goldfish Scheme. For Goldfish Scheme v17.11.2, the only missing feature for define-case-class is that generating hash-code method automatically.

(define-case-class person
  ((name string?)
   (age integer?))
  
  (define (%to-string)
    (string-append "I am " name " " (number->string age) " years old!"))
  (define (%greet x)
    (string-append "Hi " x ", " (%to-string))))

(define bob (person "Bob" 21))

(bob :to-string) ; => "I am Bob 21 years old!"
(bob :greet "Alice") ; => "Hi Alice, I am Bob 21 years old!"

git clone https://github.com/LiiiLabs/goldfish.git
xmake config --http=y --yes -vD
xmake b http
bin/http -l http/tests/chat_demo.scm

Important New Functions

• typed-define in (liii base) as an enhanced define* with type check
• define-case-class in (liii case) provides a way to define the case class (Scala) in Goldfish Scheme

(define-case-class person
  ((name string?)
   (age integer?))
  
  (define (to-string)
    (string-append "I am " name " " (number->string age) " years old!"))
  (define (greet x)
    (string-append "Hi " x ", " (to-string))))

(define bob (person "Bob" 21))

(bob 'to-string) => "I am Bob 21 years old!"
(bob 'greet "Alice") => "Hi Alice, I am Bob 21 years old!"
