Elxlisp
Lisp 1.5 M-expression. Also S-expression is available with invoke option.
Installation
make clone from GitHub
invoke
- mix elxlisp (sequential and M-expression)
- mix elxlisp seq (sequential and M-expression)
- mix elxlisp para (parallel and M-expression)
- mix elxlisp sexp (sequential and S-expression)
- mix elxlisp mexp (sequential and M-expression)
example
mix elxlisp
Lisp 1.5 in Elixir M-expression in sequential

? intersection[(A B C);(D C A)]

? quit[]
goodbyeenvironment is association list
Lisp 1.5 in Elixir M-expression in sequential
? eval[(cons x y);((x . 1)(y . 2))]
(1 . 2)
?parallel
When invoke in parallel, evlis function runs in parallel. Fibonacci runs faster in parallel. See test.meta
