05:57:57FromDiscord<k0ts> You want nimble to install dependencies inside the project directory? Use `-l` option

09:30:07FromDiscord<Clonkk> What's the best way of transforming a NimNode into a sttic[string] ?
09:30:31FromDiscord<Clonkk> The goal is to transform a potentially camelCase identifier into a snake case identifier i na macros
09:47:06FromDiscord<Elegantbeef> `repr` though if it's an identifier you can just do `.strVal` or `$`↵(@Clonkk)
09:47:39FromDiscord<Clonkk> hmm the compiler complained about it being a string and not a static[string] I must have gotten it wrong
09:47:47FromDiscord<Clonkk> (that was my idea too)
09:48:03FromDiscord<Elegantbeef> You only need a `string` cause it's in a macro in the VM
09:48:30FromDiscord<Clonkk> Even for a macro that's used as a pragma with argument ?
09:48:47FromDiscord<Elegantbeef> Got an example of what you're doing?
09:48:51FromDiscord<Elegantbeef> My money is on `string` is fine
09:49:13FromDiscord<Clonkk> sent a code paste, see https://play.nim-lang.org/#pasty=bHgpeeOy
09:49:54FromDiscord<Elegantbeef> Right so `importMe(name: static string, def: untyped)`
09:49:59FromDiscord<Clonkk> sent a code paste, see https://play.nim-lang.org/#pasty=KZzDyvgQ
09:50:06FromDiscord<Clonkk> Yep
09:50:59FromDiscord<Elegantbeef> And you want to transform `$n[0]` to `label_modifiers`?
09:51:53FromDiscord<Clonkk> Exactly, I want to be able to do `importMe` in a proc (without argument) and then it converts the proc name to snake case and calls the one with argument
09:52:00FromDiscord<Clonkk> I could also copy / pste the macro and change one line but it's ugly
09:53:27FromDiscord<Clonkk> sent a code paste, see https://play.nim-lang.org/#pasty=AxldVnSA
09:53:42FromDiscord<Clonkk> Note that the macro itself works
09:54:00FromDiscord<Clonkk> So it's really about transforming `call[0]` into a static string
09:54:54FromDiscord<Elegantbeef> Well no
09:55:09FromDiscord<Elegantbeef> You can make a proc that does the internals of the macro
09:55:12FromDiscord<Elegantbeef> Or you can do some indirection magic
09:57:30FromDiscord<Elegantbeef> Though overloading macros with typed and untyped is never really great
10:00:07FromDiscord<Elegantbeef> https://play.nim-lang.org/#pasty=bWRpwqgr but this will do
10:00:25FromDiscord<Elegantbeef> Not ideal, but it does work
10:00:50FromDiscord<Clonkk> Ah using, template, smart
10:01:00FromDiscord<Elegantbeef> You can always put a `when name isnot static[string]: {.error: "Bleh wanted a name".}`
10:02:11FromDiscord<Elegantbeef> https://play.nim-lang.org/#pasty=NXBWRDPi works better than the alternative error (comment the error out to see)
10:05:01FromDiscord<Clonkk> Eh this is for showing off Nim in a company hackathon so code doesn't have to be error proofed
10:05:12FromDiscord<Clonkk> But that's a good idea, I'll keep it in mind, thanks !
10:08:10FromDiscord<Elegantbeef> Showing off Nim and having to work around the typed vs. untyped oddities is fun
10:09:05*ntat quit (Quit: Leaving)
10:10:04FromDiscord<Clonkk> Yeah, the goal is to show just enough macros that it's useful to reduce boiler plate code but not enough that it scares people away
10:12:11FromDiscord<Elegantbeef> Reminds me of https://play.nim-lang.org/#pasty=OdQfFPUs though this sadly does not work in nested constructors so it's a useless invention
10:12:57FromDiscord<Clonkk> Was that for your constructor library ?
10:13:06FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=lnKzKvdw
10:13:11FromDiscord<Elegantbeef> Nah this was for my GUI stuff
10:13:17FromDiscord<Elegantbeef> I wanted to make anonymous procedures nicer
10:13:32FromDiscord<Elegantbeef> But sadly you can only do a single statement inside this
10:13:52FromDiscord<Clonkk> Ah yeah makes sense. I never really had a need for anonymous procedure besides the `+.` and `->` macros
10:14:03FromDiscord<Clonkk> (edit) "`+.`" => "`=>`"
10:14:07FromDiscord<Elegantbeef> Yea but `=>` and `->` are ass
10:14:22FromDiscord<Clonkk> When you do simple stuff it works
10:14:25FromDiscord<Elegantbeef> I want to define a typedef then instantiate off of it `=>` does not resolve that
10:14:26FromDiscord<nnsee> no, `))` and `((` are ass
10:14:50FromDiscord<Elegantbeef> `=>` also lets people rename the parameters which encourages bad names 😛

12:39:07capocasaWhy doesn't the static block get executed when b is imported during compile? Can I even run a block of static code when a module is compiled?
12:40:29Amun-Raworks for me
12:40:34capocasaCorrection: The above behaves as expected, the program prints foo. But this has no output:

12:42:19Amun-Rano worries :)
12:44:32capocasaAh, I see- I was walking an empty directory in a loop, so that's why my program didn't work, and then I just fumbled compiling my minimal example right.

14:50:30FromDiscord<4zv4l> is there a way to get tagged union in Nim ? (with the union pragma?)
14:51:25FromDiscord<4zv4l> other than making a variant with a `kind` field with the right enum (if possible)
14:57:11FromDiscord<bostonboston> The union pragma does effectively make tagged unions from what I understand

15:16:19Amun-Rathat's the proper way

15:19:47Amun-Rabut… object variant does not work like union, you can't access other fields
15:21:10Amun-Rayou may still use {.union.} with ordinal types (except prolly an enum), unless you want to target JS
15:21:27FromDiscord<nervecenter> In reply to @4zv4l "is there a way": Yeah object variants exist, and currently the core team has been debating how to actually implement variant syntax for a while

19:46:49FromDiscord<.bobbbob> why does nim have subrange types but not refinement types?
19:54:04FromDiscord<bostonboston> Ranges are a low bar, refinement types seem like a lot of work for not a lot of gain in the majority of cases
19:56:36FromDiscord<.bobbbob> well the subrange is a run time check, so wouldnt it just be give the type definition a predicate check and check it at run time?
19:58:36FromDiscord<.bobbbob> and then subrange would just be a refinement type
