00:04:02FromDiscord<retkid> my brain went ded
00:04:31FromDiscord<ElegantBeef> Well it's more like vim than nano, but yea
00:04:57FromDiscord<retkid> its vim but emacs
00:05:15FromDiscord<retkid> In reply to @ElegantBeef "Advertising Nim programs in": gotta keep it in the family
00:05:49FromDiscord<retkid> Advertising Nim written programs in a Nim discord to Nim programmers
00:05:51FromDiscord<retkid> #not-a-cult
00:06:30FromDiscord<ElegantBeef> Hey we dont have a rewrite it in Nim initiative so clearly arent culty
00:07:32PrestigeWe could start one
00:07:54*Prestige rewrites coreutils in Nim
00:08:11FromDiscord<retkid> rewrite python
00:08:12FromDiscord<retkid> in nim
00:08:41FromDiscord<ElegantBeef> So instead of cpython it'd be nimpython
00:09:12FromDiscord<retkid> better threading and garbage collecting!
00:09:46Prestigewhy not just use nim at that point
00:09:59FromDiscord<ElegantBeef> Cause you want python for pythony things like making me cry
00:10:53FromDiscord<retkid> why does python make you sad
00:11:40FromDiscord<ElegantBeef> Cause it's got the language design of a person that likes to test a circuit by licking an outlet
00:11:57FromDiscord<ElegantBeef> "Yea jim it's still on, my tongue is frying!"
00:12:36Prestigehahaha
00:13:30FromDiscord<retkid> lemme find some disgusting python i wrote yesterday
00:13:39FromDiscord<retkid> i didn't comment any my code because i was kinda in the zone
00:13:42FromDiscord<retkid> and reallly regret it
00:14:15FromDiscord<retkid> https://media.discordapp.net/attachments/371759389889003532/834582837150875658/unknown.png
00:14:16FromDiscord<ElegantBeef> it also relies a lot on programmer contracts like dont touch `_name` and `name`
00:14:42FromDiscord<retkid> i had to convert it back to a list because dicts aren't ordered....
00:14:46FromDiscord<retkid> for really no reason
00:14:58FromDiscord<ElegantBeef> Now rewrite it in Nim
00:15:12FromDiscord<retkid> its already been written
00:15:21FromDiscord<retkid> i wish i went back and wrote some stuff in nim
00:15:29FromDiscord<retkid> but im not rewriting a lot of this lol
00:15:44FromDiscord<retkid> though i might rewrite my write functions in nim
00:16:03FromDiscord<retkid> https://media.discordapp.net/attachments/371759389889003532/834583287582294056/unknown.png
00:16:10FromDiscord<retkid> i need to replace os.system(0 with pathlib
00:16:13FromDiscord<retkid> (edit) "pathlib" => "pathlib, ignore that"
00:16:20FromDiscord<retkid> (edit) "os.system(0" => "os.system()"
00:16:29FromDiscord<ElegantBeef> I mean i'm ignoring most of it
00:16:36FromDiscord<retkid> its disgusting
00:16:42FromDiscord<retkid> and i hope its better in nim
00:17:17FromDiscord<ElegantBeef> It can be if you believe in yourself
00:18:05FromDiscord<retkid> but i dont :(
00:18:13FromDiscord<ElegantBeef> Not with that attitude
00:18:31FromDiscord<zetashift> In reply to @uuuu "Is <@!77574388035100672> here? I": sup
00:19:40FromDiscord<retkid> @ElegantBeef do you know how to turn on syntax highlighting in moe
00:19:52FromDiscord<ElegantBeef> Should be on by default if the language is supported
00:20:00FromDiscord<retkid> using it on python and nope
00:20:13FromDiscord<ElegantBeef> Should be `:syntaxhighlighting on`

02:12:24FromDiscord<ElegantBeef> Odd, but might make sense to someone
02:18:17FromDiscord<exelotl> it also invokes it if you do `a = Foo()`
02:29:21FromDiscord<exelotl> man I've really been missing a trick with this move semantics stuff :P
02:33:03FromDiscord<demotomohiro> Maybe, `b` is assumed to be not initialized and compiler think it does not need to be destoried?
02:34:31FromDiscord<demotomohiro> Or b is not modified and doesn't need to be destroyed.
02:35:19FromDiscord<exelotl> yeah, makes sense I guess

07:23:54FromDiscord<no name fits> How do I go through an array by pointer? Something like: https://play.nim-lang.org/#ix=2WW3
07:27:40FromDiscord<ElegantBeef> @no name fits https://play.nim-lang.org/#ix=2WW4 should work for you
07:28:03FromDiscord<no name fits> Thanks
07:39:10FromDiscord<Ricky Spanish> whats the use-case? im kind of curious to know the benefits of doing it that way
07:41:16FromDiscord<ElegantBeef> There really isnt much of a usecase since it makes more sense to use a proc that takes the array, we'll just hope they're working on their own collection type and wanted to learn for that
07:42:13FromDiscord<Ricky Spanish> ah, i assumed it was for wrapping a raw array or something from c since still learning nim so seemed unusual to use a c like way to iterate an array
07:42:22FromDiscord<no name fits> Oh I was just looking for different ways to iterate collections
07:43:18FromDiscord<no name fits> When I figure out how to do performance testing reliably I wanted to set up some different test cases
07:43:42FromDiscord<ElegantBeef> I'm scared what you're testing
07:44:02FromDiscord<ElegantBeef> Nims iterators are templates so they're 0 cost
07:44:02FromDiscord<Ricky Spanish> ahaha, regardless if you do it tag me please im curious
07:44:13FromDiscord<no name fits> I'm just drawing a hex grid currently so nothing fancy
07:45:24FromDiscord<no name fits> I'm most likely just going to use a seq doe
07:45:25FromDiscord<no name fits> so
07:46:09FromDiscord<ElegantBeef> I'm slightly scared your alternative iteration methods
07:47:32FromDiscord<Rika> Do whatever in the name of performance?
07:51:25FromDiscord<sealmove> hi folks!
07:51:37FromDiscord<sealmove> noob question but how to make a 2d array?
07:51:42FromDiscord<sealmove> (not seq)
07:51:50FromDiscord<ElegantBeef> `array[w h, T]`
07:52:00FromDiscord<no name fits> I was more just curious if there actually was a difference 😛
07:52:10FromDiscord<ElegantBeef> There isn it's just a indexing difference
07:52:14*vicfred quit (Quit: Leaving)
07:52:15FromDiscord<no name fits> yeah
07:52:18FromDiscord<ElegantBeef> I can write a small example
07:52:41FromDiscord<no name fits> I'm just weird and like to test it for myself
07:52:42FromDiscord<sealmove> In reply to @ElegantBeef "`array[w * h, T]`": no thanks, I'll use seqs then :P
07:55:45FromDiscord<haxscramper> you can also use `array[w, array[h, T]]`
07:56:04FromDiscord<sealmove> In reply to @haxscramper "you can also use": oh that's what I want
07:56:29FromDiscord<sealmove> right, my brain stuck and I couldn't figure out the syntax lol
07:56:58FromDiscord<Rika> And in this case there is no down side over the w h one
07:57:08FromDiscord<ElegantBeef> Cmon this is wonderful! https://play.nim-lang.org/#ix=2WW7
07:57:35FromDiscord<sealmove> true, it's nice
07:58:25FromDiscord<sealmove> I am trying to reconstruct 2d image from dissected data channel of an 128x64 oled :D
08:00:55FromDiscord<no name fits> why is it there's no collisions even though multiplication is commutative?
08:01:32*liblq-devel joined #nim
08:01:33FromDiscord<ElegantBeef> What do you mean?
08:01:42FromDiscord<no name fits> 2 1 = 1 2
08:02:00FromDiscord<ElegantBeef> w
08:02:09FromDiscord<Rika> In reply to @no name fits "why is it there's": What do you mean
08:02:20FromDiscord<ElegantBeef> Assume they mean with the array indexing
08:02:27FromDiscord<no name fits> Isn't it a flat array? Am I missing something?
08:02:40FromDiscord<ElegantBeef> 2 5 + 0 = 10
08:02:48FromDiscord<ElegantBeef> You cannot get 10 with any other combination
08:03:37FromDiscord<no name fits> oooooh
08:03:42FromDiscord<ElegantBeef> in a 5x5 array 0-4 are the first 5 elements and 5 is the 6th
08:03:48FromDiscord<no name fits> That took me longer to get than I'd like
08:04:19FromDiscord<no name fits> I'm not very smart
08:04:25FromDiscord<ElegantBeef> i know it took me a while to solve it myself forever ago
08:04:36FromDiscord<ElegantBeef> I refused to use any documentation to figure out the 3D mapping for a 1D array
08:05:10FromDiscord<ElegantBeef> and now it makes a ton of sense and is simple expressed as "For each dimension you first calculate the area of a slice of a lower dimension"
08:05:55FromDiscord<ElegantBeef> So in a 2D array you calculate the area of a single dimension which is just either the width or height depending on your array layout
08:06:23FromDiscord<ElegantBeef> in 3D you use width and height, the very odd thing is the last dimension actually isnt a concern for indexing
08:07:08FromDiscord<sealmove> guys do you think a monochrome 128x64 oled will be use 1-bit per pixel?
08:07:21FromDiscord<ElegantBeef> I'd hope so
08:07:33FromDiscord<ElegantBeef> Might even do less
08:07:34FromDiscord<sealmove> ok, I'll make this assumption
08:07:54FromDiscord<ElegantBeef> could do the more efficient "how many of this state"
08:08:21FromDiscord<ElegantBeef> Though that's only more efficient if there is a lot of contiguous blocks
08:09:29FromDiscord<ElegantBeef> first bit being "this state" remaining being "how many"
08:09:29FromDiscord<no name fits> Also last time I asked, the answer were a little all over the place, but what do I do for automated performance testing in Nim?
08:10:17FromDiscord<ElegantBeef> As i dont know what that really classifies as, i say use benchy 😄
08:10:31FromDiscord<ElegantBeef> I'm a terrible developer
08:11:07FromDiscord<haxscramper> Benchy is good & simple to use, so I would also recommend it
08:11:26FromDiscord<ElegantBeef> Hey you only agreed with 1 of my sentences!
08:12:04FromDiscord<haxscramper> Give me a break, I can only process that much text at one time
08:12:09FromDiscord<ElegantBeef> lol
08:12:10FromDiscord<no name fits> this one? https://github.com/treeform/benchy
08:12:13FromDiscord<haxscramper> yes
08:12:15FromDiscord<ElegantBeef> Yes
08:12:17FromDiscord<no name fits> tyty
08:13:33FromDiscord<no name fits> does it give me a warning if I forget to run in something not debug?
08:13:43FromDiscord<no name fits> because I know I'll forget that
08:14:10FromDiscord<ElegantBeef> Just make a nimble task
08:14:18FromDiscord<no name fits> oh yeah that's thing

08:17:32FromDiscord<ElegantBeef> Dont say that it'll go right to my head and no one wants that
08:19:55FromDiscord<Nisha's alt> How would i use this C++ library in Nim? https://github.com/adepierre/Botcraft
08:19:56FromDiscord<Nisha's alt> :p
08:20:05FromDiscord<ElegantBeef> By wrapping it
08:20:42FromDiscord<ElegantBeef> Go to https://github.com/adepierre/Botcraft/blob/master/Examples/0_HelloWorld/src/main.cpp and replicate it in Nim, wrapping all the types you need
08:21:19FromDiscord<Nisha's alt> Ah okay!
08:21:55FromDiscord<ElegantBeef> Atleast that's what i've done for the Rpi Pico, remade the examples and wrote bindings for the code as i needed it so it could be idiomatic

12:21:54FromDiscord<zetashift> In reply to @uuuu "<@!77574388035100672> Sorry for the": because it uses ARC/ORC and gdnim itself isn't stable

16:34:42FromDiscord<carpal> if nim's compiler uses c as main IR, then why is it considered a compiler and not a transpiler?
16:36:23PrestigeProbably because it does more than just translated to c
16:36:41PrestigeTranslate*
16:38:28PrestigeBut I don't think the terminology really matters in this case
16:39:37*casaca joined #nim
16:41:23PrestigeIf it were called a transpiler, I would assume that I would end up with C code and not a binary in the end
16:42:55FromDiscord<haxscramper> In reply to @carpal "if nim's compiler uses": it does not use `C` as "main IR"
16:43:05FromDiscord<haxscramper> It uses C as backed language
16:44:16FromDiscord<haxscramper> Just as Js/C++. For IR nim uses it's AST
16:49:32FromDiscord<carpal> In reply to @Prestige "Probably because it does": but the definition of transpiler is literaly a high level to another one
16:50:12PrestigeAt a high level, the nim compiler compiles nim code to a binary
16:50:19Prestige(when using c or c++ backends)
16:50:43FromDiscord<carpal> In reply to @haxscramper "It uses C as": this means that generates c
16:50:48FromDiscord<carpal> (edit) "this" => "that"
16:51:26Prestigethe compiler's function/use is not to generate c code
16:53:36Prestigejust how the purpose of walking isn't to put my feet on the ground
16:55:45FromDiscord<carpal> good point
17:02:25FromDiscord<WSECU> How can I have nim show what gcc commands its doing when I compile?
17:03:08FromDiscord<Solitude> look at json file in nimcache
17:04:00giaco__how would you go from "let foo={"a":1,"b":2}" to string "a=1,b=2" (I need to urlencode a table-like thingy)
17:05:01FromDiscord<haxscramper> https://nim-lang.org/docs/sugar.html#collect.m%2Cuntyped%2Cuntyped collect for pairs
17:05:15FromDiscord<haxscramper> Or just iterate and add to result
17:05:25FromDiscord<WSECU> What if I want nim to just compile to C and then stop?
17:05:30FromDiscord<haxscramper> The best solution. IIRC there is no `mapIt` for pairs
17:06:01FromDiscord<haxscramper> In reply to @WSECU "What if I want": See `--fullhelp` for options, I we have something like `--noLink`

17:12:59FromDiscord<haxscramper> And I forgot that `collect` uses it's body to infer the generic parameters for result type, so it does not work for strings

19:53:22FromDiscord<Recruit_main707> pretty sure not with c and c++
19:53:45FromDiscord<haxscramper> If you write pure nim it automatically supports all targets. For the most part
19:53:57FromDiscord<WSECU> If I made a project and normally compile with C, if another user decided to compile with C++ instead, would it break it?
19:54:06FromDiscord<haxscramper> no, most likely not
19:54:16FromDiscord<ElegantBeef> The otherway around might if you rely on compiling C++ code
19:54:31FromDiscord<Recruit_main707> why

19:55:16FromDiscord<haxscramper> `src/` part is not needed of course,
19:55:18FromDiscord<Recruit_main707> afaik the only limitation of a backend is the js one about something, it was either manual allocations or something low level related

20:01:30FromDiscord<jtiai> In reply to @ElegantBeef "Why are you being": Because I'm one of those people that care about the docs (I'm documentarian partly)
20:01:46FromDiscord<ElegantBeef> Ah so you mean you're a developer
20:01:57FromDiscord<ElegantBeef> I dont see what you're bitching at
20:01:58FromDiscord<jtiai> No, i write the docs.
20:02:50FromDiscord<ElegantBeef> Lol zidsal it's fine i didnt do much
20:02:53FromDiscord<haxscramper> In reply to @jtiai "Because I'm one of": nim documentation story is not as stellar as it could've been, that is true
20:03:08FromDiscord<haxscramper> to put it lightly
20:03:22FromDiscord<haxscramper> Well, the core part is documented well enough
20:03:29FromDiscord<jtiai> And I know it's one of the hard parts. Speciall put all common 4 parts together.
20:04:02FromDiscord<ElegantBeef> The wonderful part is it's all OSS, so whenever you find docs that are subpar or wrong you can update them
20:04:17FromDiscord<haxscramper> when you know what to write in docs
20:04:28FromDiscord<haxscramper> that is - when you already got the info
20:04:34FromDiscord<ElegantBeef> Well yea
20:04:43FromDiscord<jtiai> I probably will since I got somewhat fond of Nim.
20:05:28FromDiscord<jtiai> what this "nim doc" is really supposed to do? I couldn't get any output from it even trying to type some libs I use...
20:05:30FromDiscord<haxscramper> I think it also has a lot to do with `nim doc` tool being somewhat limited
20:05:45FromDiscord<haxscramper> In reply to @jtiai "what this "nim doc"": `nim doc file.nim` generates documentation for `file.nim`
20:05:47FromDiscord<ElegantBeef> nim doc will generate html documents from doc comments and the rst in contained
20:06:06FromDiscord<ElegantBeef> It's what drives the entire stdlib docs
20:06:30FromDiscord<jtiai> Ah, since I write more comprehensive docs I've been using sphinx mainly. and asciidoc a bit.
20:06:34FromDiscord<ElegantBeef> Also runs the tests which are contained inside the `runableExample:`
20:07:02FromDiscord<ElegantBeef> Dont get what you mean by that, you can write entire tutorials in the RST as many modules have

20:07:24FromDiscord<haxscramper> https://nim-lang.org/docs/docstyle.html
20:07:34FromDiscord<jtiai> Well sphinx is rst too. + ability to parse some reference docs from python if wanted to.
20:08:20FromDiscord<haxscramper> Though to be completely honest something on the doxygen level is needed to properly support all nim features
20:08:29FromDiscord<haxscramper> There is just so much things
20:08:43FromDiscord<haxscramper> That demand careful separate handling
20:08:46FromDiscord<ElegantBeef> Well nim doc does a fair bit. Tests, code highlighting, index, and so on
20:08:53FromDiscord<ElegantBeef> But yea
20:09:07FromDiscord<haxscramper> And I'm only talking about machinery of code generation, not people writing text
20:09:20FromDiscord<haxscramper> (edit) "code" => "documentation"
20:09:25FromDiscord<haxscramper> For example documenting macros
20:09:32FromDiscord<haxscramper> OR specifically macro transforms
20:09:35FromDiscord<haxscramper> Injected variables
20:09:45FromDiscord<haxscramper> expected AST patterns
20:09:55FromDiscord<zidsal> what is this documentation you guys speak of!, understanding code I have written should be a right of passage... an honor if you will
20:09:56FromDiscord<haxscramper> surrounding scope expectations
20:10:12FromDiscord<haxscramper> like what you need to import in order for macro to work
20:10:15FromDiscord<ElegantBeef> lol zid
20:10:24FromDiscord<jtiai> tutorials, how-tos and discussions. + reference.
20:10:38FromDiscord<jtiai> that's the commmon 4 blocks of documentation.
20:11:21FromDiscord<haxscramper> tooling is also important, it is possible to have stellar documentation using only text files, but still
20:11:34FromDiscord<ElegantBeef> Discussions?
20:11:46FromDiscord<haxscramper> as a part of the documentation?
20:11:49FromDiscord<ElegantBeef> Yea
20:11:52FromDiscord<jtiai> tutorials do take user by hand and walks through an example. how-tos are like recipes to get things done and discussion is more like explanations about design decisions etc.
20:11:54FromDiscord<ElegantBeef> That's what i dont get
20:12:06FromDiscord<haxscramper> I though about running text miner on IRC logs
20:12:09FromDiscord<haxscramper> and forum posts
20:12:12FromDiscord<ElegantBeef> That's not discussion, that's "explanation" 😄
20:12:15FromDiscord<haxscramper> But the information is very fuzzy
20:12:29FromDiscord<jtiai> In documentarian vocabulary it's discussion.
20:12:32FromDiscord<ElegantBeef> Plus you'd have to filter all my messages and there is a lot of them
20:12:41FromDiscord<haxscramper> So you need somewhat good NLP skills to have something useful out of it, which I don't have yet
20:13:06FromDiscord<haxscramper> but we have 10+ years of discussions here, so it has to worth somehting
20:13:21FromDiscord<haxscramper> (edit) "somehting" => "something in terms of documentation source"
20:13:36FromDiscord<dk> I like how most of the manual and most of the system.nim doc is on one page
20:13:42FromDiscord<haxscramper> actually no, IRC logs date back to 2013 so it ls less than ten years. Still a lot
20:13:56FromDiscord<dk> much easier to keep track of what you've already read than when it's on multiple pages
20:14:14FromDiscord<haxscramper> one-page-per-proc documentation sounds
20:14:14FromDiscord<ElegantBeef> Ah you heard dk make all the stdlib on a single page with header seperating it 😛
20:15:38FromDiscord<ElegantBeef> And jtiai can you do me a favour and change that dot operators issue title to "Dot operators with type mismatch, shows assertion instead of compiler error"?
20:16:05FromDiscord<jtiai> Definitely. Just a sec.

20:54:13FromDiscord<haxscramper> In reply to @Phytolizer "i can't think of": the way to write AST in nim https://nim-lang.org/docs/macros.html#the-ast-in-nim
20:54:47FromDiscord<haxscramper> I've done 20+ different AST-like data structures at this point for various projects - never seen this approach fail
20:54:54FromDiscord<haxscramper> Works with pattern matching
20:55:18FromDiscord<haxscramper> Node type matching is checked for completeness when using `case`
20:55:41FromDiscord<haxscramper> Can put all implementation logic in a single procedure instead of spreading it over 20+ method overloads
20:55:58FromDiscord<haxscramper> Zero `ref` up/down-casting
20:56:11FromDiscord<Phytolizer> so just a tagged union
20:56:17FromDiscord<haxscramper> yep
20:56:19FromDiscord<Phytolizer> ok
20:56:25FromDiscord<Phytolizer> ill try both and see where im at
20:56:35FromDiscord<Phytolizer> i do like Rust enums

23:47:20FromDiscord<uuuu> Can I force a nim program to be compiled only as C or C++, throw an error if compiled any other way?
23:50:09FromDiscord<ElegantBeef> !eval when defined(c): {.error: "Only supports C backend".}
23:50:10NimBotCompile failed: /usercode/in.nim(1, 25) Error: Only supports C backend
23:50:33FromDiscord<ElegantBeef> Well probably `C++ backend` but there you go
23:51:06FromDiscord<uuuu> What was the code to force compile as C?
23:51:34FromDiscord<ElegantBeef> `nim cc`
23:51:45FromDiscord<ElegantBeef> or `compileToC`
23:52:09FromDiscord<uuuu> No I meant the code to give an error if a program expected to be compiled as C and got C++
23:52:20FromDiscord<ElegantBeef> I showed you in the !eval message
23:52:30FromDiscord<ElegantBeef> `when defined(cpp)`
23:53:02FromDiscord<uuuu> What about `when not defined(c)`?
23:53:12FromDiscord<ElegantBeef> works aswell
23:53:38FromDiscord<ElegantBeef> But i cannot think of a reason C cannot be compiled with C++
23:56:23krux02@ElegantBeef, C++ has more keywords than C.
23:56:48krux02therefore, some C++ keywords are valid variable names in C, but invalid in C++
23:57:14krux02and C has implicit forward declaration.
