09:45:51Zevvboth
09:46:38Zevvmetaprogramming goes all the way, you can even rewrite your AST at compile time
09:46:55ZevvConcurrency primitives are threads, thread pools, async networking
09:48:34*lritter joined #nim
09:55:01FromGitter<mratsim> tbh, I don't think there is any typed language with metaprogramming as first class as in Nim
09:55:28FromGitter<mratsim> threads is not concurrency ;). Async is.
09:56:01FromGitter<mratsim> Actually async is implemented completely via macros as a library. It's a compiler provided construct.

13:12:07FromGitter<Vindaar> @yglukhov, @Araq: regarding `when nimvm` in that json@CT PR. `nimvm` cannot be used within a type definition, correct? But I can neither declare a `BaseLexer `type both for `nimvm` and else because that gives me a redeclaration error. So how do I avoid adding another type?
13:14:14Araqadd the fields you need to the existing type?
13:42:30*Vladar quit (Remote host closed the connection)
13:43:02FromGitter<theretromaniac> Hello. I was wondering why nim doesn't have more options for web development?
13:45:10FromDiscord_<juan_carlos> options?.
13:45:43FromGitter<theretromaniac> Except jester.
13:46:04FromDiscord_<juan_carlos> You have a basic server on std lib.
13:46:27FromDiscord_<juan_carlos> You have a more complete solution on NimWC.
13:48:14FromDiscord_<juan_carlos> Theres another I never remember the name too.
13:52:11FromGitter<Vindaar> @Araq: sorry, was afk. The thing is I'm just using different types for the same fields for the VM. So adding other fields seems a bad idea?
13:56:32Araqvindaar: It's certainly better than a new type
13:56:40FromGitter<theretromaniac> Juan carlos : you mean rosecantz or something like this?
13:57:37FromGitter<Vindaar> Hm, ok. My thinking was to rather have an additional type only used at CT instead of fields in every object used at RT, which only have CT meaning
13:58:00PMunchtheretromaniac: well libs and frameworks tend to be created like this: xkcd.com/927/ guess no one has been sufficiently irked to create an alternative to jester yet :P
13:58:45FromDiscord_<juan_carlos> Dont need a ton, need good libs, maintained.

14:36:36FromGitter<bung87> ah it was my experience while using nimlsp with vscode extension
14:38:31narimiran PMunch, while you're here, can you run your binaryparse on nim devel, or is it just something on my end?
14:38:45narimiran*run=compile
14:39:38PMunchbung87, that it randomly crashed and such. If so then that's not good
14:39:43PMunchnarimiran, just a sec

14:46:56narimiransame here
14:47:11PMunchNot sure why though? Is genSym broken on devel?
14:47:40Araqkinda
14:47:50Araqthere is a bad regression that is hard to fix
14:48:00Araqcaused by a bugfix, as usual
14:50:11PMunchSo.. All libs using genSym are now unfixable?

20:11:25ZevvI'm not sure if what I'm trying to do makes sense; I'd like to have the compiler parse a snippet of Nim code into a tree if NimNodes
20:11:32Zevvwhich I want to go through at run time
20:12:03FromGitter<alehander42> but what would you do with them on runtime
20:12:10ZevvConvert them to Z3 ast

20:13:50FromGitter<alehander42> ah if it's an actual name, i am sorry

20:15:12FromGitter<alehander42> well you can just parse the nim code on runtime
20:15:14FromGitter<alehander42> i guess?
20:15:46ZevvIs the Nim lexer/parser available at runtime?
20:16:01FromGitter<alehander42> yes, you can use the compiler as a package or something
20:16:17Zevvoh, that might be an option.
20:17:22Zevvtests/tcompilerapi.nim seems a good start
