00:25:59nrds<Prestige99> What's the best way to conditionally append to a const string?
00:26:27FromDiscord<Elegantbeef> What do you mean?
00:26:58nrds<Prestige99> like I want my const string to be "foo" but if an env var exists I want to append " - {myvar}"
00:29:41FromDiscord<Elegantbeef> Also conditionally at runtime or CT?
00:29:45FromDiscord<Elegantbeef> could have a `getVar` which does it internally
00:30:44nrds<Prestige99> ct
00:30:58nrds<Prestige99> getVar?
00:31:58FromDiscord<Elegantbeef> so in your example instead of doing `fooConst` you do `getFoo`
00:34:22FromDiscord<Elegantbeef> https://play.nim-lang.org/#ix=3wHA
00:34:36FromDiscord<Elegantbeef> Oh at CT then you can just do that in a block
00:37:23FromDiscord<Elegantbeef> Something like this https://play.nim-lang.org/#ix=3wHC

01:52:22FromDiscord<JSONBash> is there a way I can filter a seq of objects by whether a field exists?
01:52:36FromDiscord<impbox [ftsf]> a seq will be of all the same kind of object
01:52:40FromDiscord<impbox [ftsf]> so the fields would be the same
01:52:43FromDiscord<Elegantbeef> "exists"?
01:52:56FromDiscord<impbox [ftsf]> a seq of ref objects to different child types?
01:53:59FromDiscord<JSONBash> ^ exactly sorry
01:54:08FromDiscord<JSONBash> ref object of _
01:54:22FromDiscord<impbox [ftsf]> that would be a runtime type info thing, not sure if that's possible
01:54:32FromDiscord<impbox [ftsf]> you could filter on if it's a subtype of X
01:54:55FromDiscord<Elegantbeef> Well you'd need to store the information of what types have X field
01:55:15FromDiscord<Elegantbeef> Then you could check if the object is of one of those
01:56:22FromDiscord<JSONBash> In reply to @impbox "you could filter on": how would I do that?
01:56:44FromDiscord<Elegantbeef> Well you'd have to make a macro that does it or manually do it
01:58:02FromDiscord<impbox [ftsf]> https://play.nim-lang.org/#ix=3wHS
01:58:53FromDiscord<impbox [ftsf]> but I don't think you could do `filterIt(it.hasField("fieldA"))` for example
01:59:16FromDiscord<impbox [ftsf]> unless you made your own proc that returned whether that was true or not
01:59:18FromDiscord<Elegantbeef> Without making that RTTI nope
01:59:56FromDiscord<Elegantbeef> I dont think there is a mechanism in nim to get all objects that inherit from one
02:01:03FromDiscord<impbox [ftsf]> https://play.nim-lang.org/#ix=3wHW not a nice solution, but you can do this
02:01:26FromDiscord<impbox [ftsf]> i'd suggest rethink what you're trying to do =)
02:01:33FromDiscord<impbox [ftsf]> what are you trying to do?
02:01:37FromDiscord<Elegantbeef> I concur
02:03:01FromDiscord<JSONBash> I tried the examples you provided but tried to access the fieldX of the found items and got an error
02:03:30FromDiscord<Elegantbeef> Well the list is still a liist of `Base`
02:03:36FromDiscord<impbox [ftsf]> what is the error you got?
02:03:38FromDiscord<Elegantbeef> So you'd need to then mapit
02:04:15FromDiscord<Elegantbeef> Filterit removes all that dont fulfil the example, you now need to convert to the type you want
02:04:19FromDiscord<JSONBash> I am using the logging library and trying to filter getHandlers() by type of RollingFileLogger so i can access the file field
02:05:46FromDiscord<JSONBash> https://play.nim-lang.org/#ix=3wHX
02:06:25FromDiscord<Elegantbeef> Is how you'd do it https://play.nim-lang.org/#ix=3wHY
02:06:48FromDiscord<Elegantbeef> filterit doesnt convert the type, it just removes any object that doesnt match the filter
02:07:10FromDiscord<JSONBash> ooooh shit yeah i get that
02:07:34FromDiscord<impbox [ftsf]> baseName isn't exported though
02:07:59FromDiscord<impbox [ftsf]> so you can't access it from outside the logging module
02:08:09FromDiscord<JSONBash> meaning tog e tfile
02:08:13FromDiscord<JSONBash> meaning to get file
02:08:39FromDiscord<JSONBash> but it is still seq[Logger]
02:08:43FromDiscord<JSONBash> which doesn't have file
02:09:00FromDiscord<JSONBash> i need the extra step to convert to seq of FileLogger
02:09:09FromDiscord<impbox [ftsf]> yep, but even then you won't be able to read baseName
02:09:13FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/dn3
02:09:38FromDiscord<Elegantbeef> Oh there is no accessor for the logger file name
02:10:53FromDiscord<JSONBash> In reply to @impbox "yep, but even then": yeah it was a bad example by me, i want to be reading file which is external. Don't want baseName at all
02:11:09FromDiscord<JSONBash> i want the File
02:11:20FromDiscord<Elegantbeef> Anywho same example for inheritance

02:12:23FromDiscord<Elegantbeef> There you go even with RSI have a better answer \:P
02:13:16FromDiscord<impbox [ftsf]> would be nice to have a template that does the conversion if it is of the type

02:40:04FromDiscord<Elegantbeef> What do you mean stream it?
02:41:41FromDiscord<impbox [ftsf]> read it as the data comes in before it's fully transferred i'm guessing
02:42:10FromDiscord<impbox [ftsf]> i'm not sure if httpclient supports that
02:42:34FromDiscord<hamidb80> i wanna implement something like `EventSource` in nim
02:43:16FromDiscord<impbox [ftsf]> via client.bodyStream perhaps
02:44:07FromDiscord<impbox [ftsf]> https://github.com/nim-lang/Nim/issues/13856
02:44:41FromDiscord<Elegantbeef> So it's possible just you'd have to do it \:D
02:44:43FromDiscord<impbox [ftsf]> ahh that issue is for sending via streaming not receiving
02:46:36FromDiscord<Elegantbeef> Well event source is server -\> client so if you just want that logic https://forum.nim-lang.org/t/6103#39804 might help

02:51:55FromDiscord<hamidb80> thanks
02:54:33madpropsis it possible to have an enum that can't be nil, that it defaults to one value?
02:55:01madpropsto avoid parameters like: nm: NumMode = NumMode.number
02:58:14FromDiscord<impbox [ftsf]> enums cannot be nil
02:58:23FromDiscord<impbox [ftsf]> and they default to the value at 0
03:05:03madpropsoh
03:09:12FromDiscord<Elegantbeef> The only things that are nilable are `ref T` and pointers
03:09:45madpropsso was {.pure.} removed or not?
03:10:02FromDiscord<Elegantbeef> No it's still here
03:10:39madpropshttps://forum.nim-lang.org/t/4190
03:10:45madpropsi guess that's not relevant then
03:10:52FromDiscord<hamidb80> i dont see `offtopic` channel
03:11:55FromDiscord<Elegantbeef> Pure now is needed for overlap but a pure enum doesnt force it into a namespace
03:12:13FromDiscord<Elegantbeef> If there is no overlap you can use the enum field as is
03:12:20FromDiscord<Elegantbeef> I say overlap but mean ambiguity
03:18:11madpropsI see
03:25:24madpropsif enums default to 0, how can I use them as optional parameters?
03:25:30madpropswith a default value
03:25:41madpropsI think it's failing after I removed the = optional
03:25:47madprops= default *
03:26:08madpropsi think it treats the signature of the proc differently
03:26:54FromDiscord<Elegantbeef> Just like anything else https://play.nim-lang.org/#ix=3wI9
03:27:44madpropsoh huh didn't have to specify it's a Color
03:28:21FromDiscord<Elegantbeef> Well optionals have type inference

06:29:43FromDiscord<treeform> In reply to @Elegantbeef "Let's look at treeforms": I am very surprised that array of two floats is slower then object with x, y members which is slower then object of array of two floats. I mainly keep the other representations around to see if other compilers like them better.
06:30:12FromDiscord<treeform> I make sure that all 3 representations keep working and pass the tests

06:31:59FromDiscord<treeform> like 10-20% based on operations
06:32:10FromDiscord<impbox [ftsf]> interesting
06:35:07FromDiscord<treeform> To see for yourself clone vmath repo and bench_raytracer with the different compile flags.
06:35:30FromDiscord<treeform> See timings here: https://github.com/treeform/vmath#vector-and-matrix-representation-and-benchmarks
06:35:32nrds<R2D299> itHub: 7"Math vector library for graphical things."
06:35:52FromDiscord<treeform> vmathObjArrayBased beats vmathObjBased
06:35:58FromDiscord<treeform> which really beats vmathArrayBased
06:38:04FromDiscord<treeform> I was benching glm vs vmath and glm was faster and I traced it to using object arrays: https://github.com/stavenko/nim-glm/blob/master/glm/vec.nim#L22
06:38:11FromDiscord<treeform> Now we are about the same speed
06:40:03FromDiscord<Elegantbeef> Have you checked with C to see if it also has speed differences on struct vs. array?
06:42:02FromDiscord<treeform> No. I am just lazy. Its very hard to check this kind of stuff small benchmarks.
06:42:15FromDiscord<impbox [ftsf]> yeah wow
06:42:18FromDiscord<treeform> Adding a million floats together just does not cut it.
06:42:33FromDiscord<treeform> You got to run it through a real program like a ray tracer

06:42:50FromDiscord<treeform> yep
06:42:51FromDiscord<impbox [ftsf]> what is your problem arrays
06:43:15FromDiscord<treeform> they can't be copied by the compiler and require memcpy
06:43:44FromDiscord<treeform> sent a code paste, see https://play.nim-lang.org/#ix=3wIs

06:45:36FromDiscord<treeform> In theory vmathObjBased should be same as vmathObjArrayBased, but they are not
06:45:52FromDiscord<treeform> Strange ah?
06:46:40FromDiscord<impbox [ftsf]> very odd indeed
06:47:21FromDiscord<impbox [ftsf]> with a 2 element array you think the compiler would just do what it does with a struct
06:47:41FromDiscord<treeform> well C does not allow =
06:47:45FromDiscord<treeform> struct = struct
06:47:52FromDiscord<treeform> but array = array does not work
06:47:59FromDiscord<treeform> and needs memcpy(array, array)
06:48:05FromDiscord<treeform> so that is why its slower
06:48:13FromDiscord<impbox [ftsf]> yeah but array[0] = array[0]; array[1] = array[1]
06:48:17FromDiscord<treeform> even if array is 8 bytes
06:48:49FromDiscord<treeform> I don't fully understand it though
06:48:56FromDiscord<impbox [ftsf]> i guess you could override the copy operator to just do it elementwise
06:49:20FromDiscord<treeform> see if that makes it faster?
06:49:32FromDiscord<treeform> modify the array branch in vmath
06:50:25FromDiscord<treeform> if obj of array is faster
06:50:42FromDiscord<treeform> that means all nim's objects that have members of one type would be faster when "arrayed"
06:51:21FromDiscord<treeform> can nim compiler just do that then?

07:15:17madpropsany way around it?
07:16:19madpropsmaybe I'll try making the tuples an object
07:16:44FromDiscord<Elegantbeef> Well the table constructor needs better inference

16:45:47FromDiscord<trenta3> Hi! I just got started with Nim. What is the nim/nimble command to create a C source file of my binary?
16:47:11FromDiscord<undersquire> you just compile it normall and check your nim cache folder for the C files
16:49:58FromDiscord<Rika> please note that the c file emitted is not meant to be human readable
16:50:13FromDiscord<trenta3> In reply to @undersquire "you just compile it": I want to generate C source files for another OS and later compile those under the other OS where header files are there
16:50:46FromDiscord<trenta3> So obviously I cannot compile it normally since it wouldn't build under my OS
16:50:46FromDiscord<undersquire> In reply to @Rika "please note that the": will they ever improve its readability?
16:50:54FromDiscord<undersquire> or is that not a concern
16:51:08FromDiscord<undersquire> In reply to @trenta3 "I want to generate": you should be able to just compile those C sources anywhere
16:51:55FromDiscord<konsumlamm> In reply to @undersquire "or is that not": it's not really a concern, since they're not supposed to be readable in the first place
16:52:46FromDiscord<undersquire> yeah makes sense, as long as you were just working with the nim portion and didnt care about modifying the generated C sources
16:53:48FromDiscord<Rika> which is a majority of the users
16:54:22FromDiscord<undersquire> yeah
16:54:27FromDiscord<trenta3> In reply to @undersquire "you should be able": Thanks. I will try
16:54:47FromDiscord<undersquire> u will need nim installed on those systems since the C sources are using the nim headers

17:07:55FromDiscord<dankrad> Looks like this test isn't newly added. But I don't get why it's failing.
17:08:15FromDiscord<leorize> it's a Nim VM test that's very sensitive to performance changes
17:08:46FromDiscord<leorize> this includes the CI instance that runs the test, if it's a VM and the CPU is borrowed by an another VM for awhile, then that test can fail
17:08:50FromDiscord<leorize> it's pretty annoying tbh
17:09:24FromDiscord<Rika> is there any way to fix that issue
17:09:34FromDiscord<dankrad> means in my case that it just failed again? that it doesn't have anything to do with my pr?
17:10:18FromDiscord<leorize> yea, usually it has little to do with your PR, unless you modified the compiler vm
17:11:55FromDiscord<dankrad> well, i didn't. I just modified in `macros` the `customPragmaNode` function.

18:57:25arkanoidhaxscramper, are you sure that limiting code in working example is a good thing for an issue? I've been told more than once that giving context is better as it points to the intended direction of the programmer and helps devs to focus on what users are trying to do
18:57:52FromDiscord<Yardanico> well, it's good to minimize the code as long as you get the same crash/c compiler error
18:58:06FromDiscord<Yardanico> because in virtually every case it's some small part of the code triggering the issue
18:58:30arkanoidYardanico: when I do that, I generally get "but what was you trying to achieve?"
18:58:31FromDiscord<haxscramper> if you have large piece of code it makes harder to pinpoint what causes it exactly
18:58:48FromDiscord<Yardanico> In reply to @arkanoid "<@177365113899057152>: when I do": weird, haven't seen that response in Nim issues
18:59:10FromDiscord<haxscramper> Smaller piece of code is also easier to understand
18:59:14FromDiscord<Yardanico> when asking in real time chats - yes, you might get that response, but the smaller the code to reproduce the issue is, the better for issues
18:59:16arkanoidyeah but I've already minimized. It's an extrapolation from a 700loc file
18:59:35FromDiscord<haxscramper> I cut it down twice by randomly deleting code so ...
18:59:48FromDiscord<Yardanico> yeah, that's what I was doing last year when testing random libs with ARC :P

19:29:08FromDiscord<haxscramper> [enthus1ast](https://matrix.to/#/@sn0re:matrix.code0.xyz)\: I finally managed to test nimja - everything works just as I expected, and it looks it would be the thing I use for haxdoc and all my projects that require any sort of file templating.
19:35:35FromDiscord<enthus1ast> Nice! I was also working on the runtime evaluation (dynamicAgain branch), which kinda works, but it cannot yet put values into the vm. And I'm unsure if both models can work the same, I don't know if I can (and should) feed all visible variables and procs into the vm.
19:37:03FromDiscord<haxscramper> I think it would be better to allow explicitly listing "captured" variables, for basic interop support
19:37:12FromDiscord<enthus1ast> Yes
19:37:14FromDiscord<haxscramper> But not necessarily all.
19:37:31FromDiscord<haxscramper> Although I don't know what would be the best approach for that either
19:38:02FromDiscord<haxscramper> Need more use cases& requirements and then expected behavior can be formulated
19:38:21FromDiscord<enthus1ast> Then maybe, I should look for alternatives to make the development workflow more pleasant, maybe automatic shared object compilation/loading/binding
19:39:28FromDiscord<RattleyCooper> Anybody know what compile times are like on a raspberry pi 4? My computer totally died Saturday night 😢 I can't afford to fix it atm so I might fallback to using the rpi 4 and am curious as to what I can expect
19:39:43FromDiscord<enthus1ast> At least the "I design my site, an play with values" usecase would be more pleasant
