ivm

ivm is a simple vm built for a prototype-based language ink

Prerequisites

cmake >= 2.8
gcc >= 4.8.4 or clang >= 3.0

Build

Build using cmake

cmake -DVERSION=release
make

After Building

run tests or anything you write

make test
build/bin/ink hello.ink

Examples(of ink)

ink is a dynamically-typed language with...

Weird grammar

// js-like prototype mechanism
list.proto.map = fn f:
	[ f(i) for loc i in base ]

// partial applied function
[ 1, 2, 3 ].
	map(1 .+(_)).
	map {
		i -> i * 2
	}.
	map(print)

Natively supported coroutine

loc c = fork fn [ (yield i * 2) for loc i in range(10) ]

while c.alive():
	print(resume c)

All sorts of overloading(which is bad)...

// context overload
loc = loc.clone()

list.proto.reduce = fn f: {
	assert base.size() > 1

	loc init = base[0]
	
	for loc e in base.slice(1):
		init = f(init, e)

	init
}

list.proto.map = fn f: [ f(i) for loc i in base ]

// is capital or non-capital letter
// custom operators
string.proto.+? =
	fn c = base.ord(): c >= "A".ord() && c <= "Z".ord()
string.proto.-? =
	fn c = base.ord(): c >= "a".ord() && c <= "z".ord()

string.proto.~ = fn:
	base.
		chars().
		map(fn c:
				if +? c:
					c.ord() - "A".ord() + "a".ord()
				elif -? c:
					c.ord() - "a".ord() + "A".ord()
				else:
					c.ord()
			).
		map(fn c: c.char()).
		reduce(fn i, a: i + a)

print(~"hELLO, WORLD!")

... And tolerable performance

loc fib = fn n:
	n < 2 ?
		1 : fib(n - 1) + fib(n - 2)

print(fib(30))
