Irispl

Yet another lisp-language. Typed-scheme in C++ VM

✅ List
✅ String
✅ Number
✅ Quote
✅ Function (Of course)
✅ Class & Instance - Inheritance

❎ C++ Interface
❎ Garbage Collection
❎ Package Manager

Usage

Compile

Prequisities

• only tested under MacOS and Ubuntu
• g++ or clang++
• CMake
• boost (check https://www.boost.org/)

command

clone it.....
cd irispl
mkdir -p build
cd build
cmake .. & make
./iris

Run

./iris is the REPL program.
./iris path/to/your/iris.scm/file will compile your iris code and execute it via the VM.

User Manual

Class

(class class-name (init-variable0 init-variable1 ...)
  (super (father-class-name value)
    ((method-name0 (self variable0) method-body0)
     (method-name1 (self variable0) method-body1))))

Let

lexical binding: variable will be defined and has init as default value. the scope of these varibles is inside the let application

(let ((variable init)
      (variable init)
      (expression)))

Function Arbitrary Arguments Supported

general form:

(lambda (arg0 arg1 . agrs)
  (use-agrs-as-list)))

example:

(define sum-list 
  (lambda (args)
    (if (pair? args)
        (+ (car args) (sum-list (cdr args)))
        (car args))))

(define sum
  (lambda (arg0 agr1 . args)
    (+ (+ arg0 agr1) (sum-list args))))

(sum 1 2 3 4 5) -> 15

Apply

(apply function argument-list)

equivalent to:

(function arg0 arg1 ... argX)
