Setting finalizer on object hierarchy won't compile with --gc:arc

The problem original problem is with finalizers and arc. Not destructors and refc. Usually refc seems to work fine with both destructors/finalizers

Setting finalizer on object hierarchy won't compile with --gc:arc

This works with `--gc:arc`: type Parent* = object of RootObj Child* = object of Parent proc `=destroy`*(self: var Parent) = echo "Parent delete" proc `=destroy`*(self: var Child) = echo "Child delete"

profiler for mac?

Since I'm on a mac and I wanted to try & write a simple profiler myself to just spit out times. eg if I have this example code (just a quick example that does nothing): import std/[sequtils] proc A(x: seq[int]) = for _ in 0 .. x.high var y = x proc B(

Setting finalizer on object hierarchy won't compile with --gc:arc

To make runtime branching for `delete` work you need to make it a `method`. [See manual](https://nim-lang.org/docs/manual.html#methods)

Setting finalizer on object hierarchy won't compile with --gc:arc

@filcuc if what @guibar says this is real, this is a showstopper for current NimQml design + arc. Better to stick with --gc:refc and consider it a requirement, or branch code ad compile time: * when arc use =destroy * when refc use finalizers Maybe there's a third option to use =destroy

I edited my post to properly answer your question.

Bug of newSeqWith with Slice

`typeof` has default TypeOfMode `typeOfIter` which evaluates as `int` for `0 .. 10` since `0 .. 10` is also an integer iterator as well as a slice constructor. Use `typeOfProc`. [typeof docs](https://nim-lang.org/docs/system.html#typeof%2Cuntyped) template newSeqWith*(len: int, ini

Working with tables and strict funcs

Use `var` and `var Foo`. {.experimental: "strictFuncs".} import tables type Foo = ref object data: Table[string, int] func readData(f: var Foo, k: string): int = f.data[k] if isMainModule: var f = Foo(data: initTable[string

Privacy offensive - remove Google Analytics from the Nim website

Note that there is a repo issue about this: I think plausible is an excellent alternative, one of the things I like particularly is the fact that dashboards can be made public (as shown by Hugo) I actually reached out to @dom96 some time ago and

Working with tables and strict funcs

Yes, that clears the compiler error, but it's actually the opposite of what I want. I want the compiler to see that `f` is immutable, so in a more complicated scenario it can catch any errors where I do mutate it by accident.

Plausible is really nice, here's an example of the analytics for SciNim's getting-started page (which @pietroppeter is kindly providing us with) of what kind of stats you get: [Plausible Analytics](https://plausible.io/scinim.github.io%2Fgetting-started)

Working with tables and strict funcs

I like the strict funcs experimental feature, and I like using it in my side projects. But I'm having a small issue and wanted to see what others think about it. Here's the setup: I have a reference type with a private member that is a table. I want a pure function to be able to read from that

Atomics: attempting to call undeclared routine: 'testAndSet'

Seems like you've been hit by a generic symbol resolution bug: Here: `while location.guard.testAndSet(moAcquire): discard` It should probably be rewritten `while testAndSet(location.guard, moAcquire)` due to a limitation with method call syntax in templates. That or you've been hit with the i

I started playing with the [atomics](https://nim-lang.org/docs/atomics.html) module this morning, but I hit a roadblock pretty quick. I've got two files in my project... a src file and a test file: # src/OpenAddrTable.nim import std/atomics type OpenAddrTab

nimscript - import configuration file

With a bit of `include` trickery you can actually use Nimscript as the config language (without the overhead of booting up the Nim compiler more than once). This is nice because you get proper typechecking and error messages, and you can use procs/templates to introduce additional rules and cons

Bug of newSeqWith with Slice

I found that the newSeqWith may fail when init is constant Slice like 0..10 . I also found that if init is typed, it can be compiled. Should it be untyped? template newSeqWith*(len: int, init: untyped): untyped = var result = newSeq[typeof(init)](len) for i in 0 ..< len:

Setting finalizer on object hierarchy won't compile with --gc:arc

Honestly i don't get why it should not work conceptually. Child and Parent are two diffrent types each one with its own finalizer/destructor.

Setting finalizer on object hierarchy won't compile with --gc:arc

I think it is a bug but possibly unfixable, --gc:arc tries to turn finalizers into destructors but the design of these two features is different. A workaround is to use explicit destructors: type Parent* = ref object of RootObj Child* = ref object of Parent proc
