checking out the latest in the JS flavor of the month and came really impressed with bun.sh
they even shoutout nimlang in the docs, hwoever, unfortunately only provide examples for Rust and Zig (bun is developed in zig)
Thats good news - i suppose they want the nim-stdlib, cos Zig cannot provide such, yet :)
As i'm working on improving the QuickJS4Nim-project i'd say - lets have a nice competition here.
class SomeClass:
static:
const someConst = 42
var counter: int
# class-member-fn
method getCounter(): int = SomeClass.counter
var x: int # defines a instance var
# constructor
method init(): SomeClass = returns a instance
method add( this: SomeClass, y: int ) = this.x += y
The code above is a blueprint for a JS-Class. The code will never be used on the Nim-side. It's scanned by a macro and then produces a JS-Class including : de-/allocation on the JS-side, registration of the class, etc by calling the QuickJS-APIs. A opaque Nim-Type works almost the same. It registers a opaque-type with the VM including allocation/deallocation, ctor, etc. If somebody would know a way to scan the surface of a nim-module with a macro. Then one could save most of the following declarations for e.g. a PackedSet/IntSet :
NimType IntSet :
static:
method init*() :IntSet =
result = initIntSet()
method from*( val: JSValue ) :IntSet =
echo "static::fromIter"
method IntSet*( ctx: JSContext, args: varargs[int] ) :IntSet =
var iset = IntSet_init()
for v in args :
iset.incl v
let t = JSIntSet()
result = iset
# QuickJS implements operator-overloading
method `-`*( this: var IntSet, other: IntSet ) =
echo "operator minus"
intsets.excl this, other
method `+`*( this: var IntSet, other: IntSet ) =
echo "operator plus"
intsets.incl this,other
method `()`*( this, other: IntSet ) :IntSet =
echo "call-operator"
method incl*( this: var IntSet, other :IntSet ) =
intsets.incl this, other
method excl*( this: var IntSet, other :IntSet ) =
intsets.excl this, other
method union*( this, other: IntSet ) :IntSet =
intsets.union this, other
method disjoint*( this, other: IntSet ) :bool =
intsets.disjoint this, other
